Case Reports

Primary cardiac tumors, either benign or malignant, are very rare. The combined incidence is 0.002% on pooled autopsy series.¹ The benign tumors account for 63% of primary cardiac tumors and include myxoma, the most common, and followed by papillary fibroelastoma, fibroma, and hemangioma. The remaining 37% are malignant tumors, essentially predominated by sarcomas.¹

Although myxoma is the most common tumor arising in the left atrium, we present a case that shows that sarcoma can also arise from the same chamber. In fact, sarcomas could mimic cardiac myxoma.² The cardiac sarcomas can have similar clinical presentation and more importantly can share similar histopathological features. Sarcomas may have myxoid features.² Cases diagnosed as cardiac myxomas should be diligently worked up to rule out the presence of sarcomas with myxoid features. In addition, foreign bodies have been found to induce sarcomas in experimental animals.^3,4 In particular, 2 case reports have described sarcomas arising in association with Dacron vascular prostheses in humans.^5,6 We present here the case of a patient who was diagnosed with cardiac pleomorphic sarcoma 8 years after the placement of a Dacron graft.
 

Case presentation and summary

A 56-year-old woman with history of left atrial myxoma status after resection in 2005 and placement of a Dacron graft, morbid obesity, hypertension, and asthma presented to the emergency department with progressively worsening shortness of breath and blurry vision over period of 2 months. Acute coronary syndrome was ruled out by electrocardiogram and serial biomarkers. A computed-tomography angiogram was pursued because of her history of left atrial myxoma, and the results suggested the presence of a left atrial tumor. She underwent a transesophageal echocardiogram, which confirmed the presence of a large left atrial mass that likely was attached to the interatrial septum prolapsing across the mitral valve and was suggestive for recurrent left atrial myxoma (Figure 1). The results of a cardiac catheterization showed normal coronaries.

The patient subsequently underwent an excision of the left atrial tumor with profound internal and external myocardial cooling using antegrade blood cardioplegia under mildly hypothermic cardiopulmonary bypass. Frozen sections showed high-grade malignancy in favor of sarcoma. The hematoxylin and eosin stained permanent sections showed sheets of malignant pleomorphic spindle cells focally arranged in a storiform pattern. There were areas of necrosis and abundant mitotic activity. By immunohistochemical (IHC) stains, the tumor cells were diffusely positive for vimentin, and negative for pan-cytokeratin antibody (AE1/AE3), S-100 protein, Melan-A antibody, HMB45, CD34, CD31, myogenin, and MYOD1. IHC stains for CK-OSCAR, desmin, and smooth muscle actin were focally positive, and a ki-67 stain showed a proliferation index of about 80%. The histologic and IHC findings were consistent with a final diagnosis of high-grade undifferentiated pleomorphic sarcoma (Figure 2).

Discussion

This case demonstrates development of a cardiac pleomorphic sarcoma, a rare tumor, after placement of a Dacron graft. Given that foreign bodies have been found to induce sarcomas in experimental animals,^3,4 and a few case reports have described sarcomas arising in association with Dacron vascular prostheses, ^5-10 it seems that an exuberant host response around the foreign body might represent an important intermediate step in the development of the sarcoma.

There is no clearly defined pathogenesis that explains the link between a Dacron graft and sarcomas. In 1950s, Oppenheimer and colleagues described the formation of malignant tumors by various types of plastics, including Dacron, that were embedded in rats. ^3,4 Most of the tumors were some form of sarcomas. It was inferred that physical properties of the plastics may have some role in tumor development. Plastics in sheet form or film that remained in situ for more than 6 months induced significant number of tumors compared with other forms such as sponges, films with holes, or powders.^3,4 The 3-dimensional polymeric structure of the Dacron graft seems to play a role in induction of sarcoma as well. A pore diameter of less than 0.4 mm may increase tumorigenicity.¹¹ The removal of the material before the 6-months mark does not lead to malignant tumors, which further supports the link between Dacron graft and formation of tumor. A pocket is formed around the foreign material after a certain period, as has been shown in histologic studies as the site of tumor origin.^9,10

At the molecular level, the MDM-2/p53 pathway has been cited as possible mechanism for pathogenesis of intimal sarcoma.^12,13 It has been suggested that endothelial dysplasia occurs as a precursor lesion in these sarcomas.¹⁴ The Dacron graft may cause a dysplastic effect on the endothelium leading to this precursor lesion and in certain cases transforming into sarcoma. Further definitive studies are required.

The primary treatment for cardiac sarcoma is surgical removal, although it is not always feasible. Findings in a Mayo clinic study showed that the median survival was 17 months for patients who underwent complete surgical excision, compared with 6 months for those who complete resection was not possible.¹⁵ In addition, a 10% survival rate at 1 year has been reported in primary cardiac sarcomas that are treated without any type of surgery.¹⁶

There is no clear-cut evidence supporting or refuting adjuvant chemotherapy for cardiac sarcoma. Some have inferred a potential benefit of adjuvant chemotherapy although definitive conclusions cannot be drawn. The median survival was 16.5 months in a case series of patients who received adjuvant chemotherapy, compared with 9 months and 11 months in 2 other case series.^17,18,19 Multiple chemotherapy regimens have been used in the past for treatment. A retrospective study by Llombart-Cussac colleagues, analyzed 15 patients who had received doxorubicin-containing chemotherapy, in most cases combined with ifosfamide or dacarbazine. ²⁰ Resection was complete in 6 patients and incomplete in 9. The patients were given chemotherapy within 6 weeks of surgery. Five patients developed metastatic disease during therapy. The median interval to first relapse was 10 months and overall median survival was 12 months in these patients.²⁰ Other regimens that have been used for treatment are mitomycin, doxorubicin, and cisplatin (MAP); doxorubicine, cyclophosphamide, and vincristine (DCV); ifosfamide and etoposide (IE); ifostamide, doxorubicin, and decarbazine; doxorubicin and paclitaxel, and paclitaxel alone.⁴ Of those, a patient with on the IE survived the longest, 32 months.

Radiation showed some benefit in progression-free survival in a French retrospective study.²¹ Radiation therapies have been tried in other cases, as well in addition to chemotherapy. However, there is not enough data to support or refute it at this time.^15,17,20 Several sporadic cases reported show benefit of cardiac transplantation.^21,22
 

Conclusion

In consideration of the placement of the Dacron graft 8 years before the tumor occurrence, the anatomic proximity of the tumor to the Dacron graft, and the association between sarcoma with Dacron in medical literature, it seems logical to infer that this unusual malignancy in our patient is associated with the Dacron prosthesis.

Sjogren syndrome (SS) is a chronic inflammatory autoimmune disorder characterized by lymphocytic infiltration of lacrimal and salivary glands causing sicca syndrome.¹ The disease can extend beyond the exocrine glands, and systemic manifestations, including vasculitis, lung, renal or neurologic involvement, can occur.² Lung disease associated with SS is more commonly seen in women aged ≥ 60 years. The most common symptoms include dry cough, chest pain, and dyspnea on exertion. Sjogren syndrome also may produce several respiratory complications, including bronchial hyperresponsiveness, bronchiolitis, bronchiectasis, pulmonary infections, pulmonary amyloidosis, pulmonary embolism, pulmonary hypertension, lymphomas, and interstitial lung diseases (ILD).² Although ILD typically occurs 5 to 10 years after the onset of SS, lung disease can precede SS.

Pulmonary involvement is associated with systemic manifestations, hypergammaglobulinemia, and anti-SSA and anti-SSB antibodies.² Laboratory tests that confirm a diagnosis of SS include antinuclear antibody (ANA), anti-Ro/SSA, and anti-La/SSB antibodies.² Pulmonary function test (PFT) results appear to reflect impairment of either the lung (restrictive syndrome) or airways (obstructive syndrome).² Imaging abnormalities may include ground-glass attenuation, subpleural small nodules, nonseptal linear opacities, interlobular septal thickening, bronchiectasis, and cysts.³ Therefore, many ILD cases show similar imaging and pathologic findings; nevertheless, they have identifiable etiology that are not idiopathic.

Case Presentation

A 67-year-old man with a medical history of hypertension, peripheral vascular disease, and keratoconjunctivitis sicca (treated with eye drops) developed progressive shortness of breath, dyspnea on exertion, and weight loss (40 pounds) over the course of 6 months. A pulmonary function test showed a restrictive abnormality with decreased diffusing capacity of the lungs for carbon monoxide (eFigure available online at www.fedprac.com). A chest computed tomography (CT) scan showed the presence of significant thickening of the interlobular septi that was more pronounced in the subpleural regions of the lungs and lower lobes, which was consistent with usual interstitial pneumonia. A chest X-ray conducted 4 months prior showed no significant acute cardiopulmonary abnormalities (Figure 1). An open lung wedge biopsy revealed chronic organizing pneumonia with mild interstitial chronic inflammation, smooth muscle hypertrophy, and honeycomb changes consistent with usual interstitial pneumonia.

The patient had been diagnosed with idiopathic pulmonary fibrosis (IPF) by a private physician and started pirfenidone and oxygen therapy. Three months later the patient presented to the VA Caribbean Healthcare System in San Juan Puerto Rico when he developed an exacerbation of IPF. The patient reported having fever, chills, dry cough, night sweats, and marked shortness of breath. He was found hypoxemic (partial pressure of O₂ was 50 mm Hg) and required a venturi mask set to 50% fractioned of inspired O₂ to maintain a peripheral oxygen saturation around 90%. A chest X-ray showed decreased lung volume with bilateral interstitial and alveolar disease (Figure 2). Leukocytosis was present at 17×10^-3/µl. The chest CT scan showed interval worsening of diffuse ground-glass airspace opacities and worsening of interstitial opacities; there

After careful clinical assessment (+ dry eyes) and radiographic pattern evaluation (diffuse bilateral interstitial and ground-glass opacities), the clinical diagnosis of IPF was queried after the patient’s rheumatologic workup came back positive for ANA and anti-Ro/SSA tests. Since the etiology of ILD was secondary to SS, pirfenidone was discontinued, and the patient was started on steroid therapy with subsequent marked clinical improvement. Parotid biopsy revealed the presence of inflammatory cells supporting the diagnosis of ILD associated to SS. The patient was discharged home on a tapering dose of steroids. Four months after therapy with steroids, a follow-up chest CT scan without contrast showed a chronic ILD with improved ground-glass opacities (Figure 4). The patient currently is in good health without oxygen supplementation.

Discussion

Diagnosis of SS is challenging, since it may mimic other conditions such as IPF. The most common type of SS-associated ILD is nonspecific interstitial pneumonia (NSIP), although usual interstitial pneumonia (UIP) can be visualized, as in this case study. Usual interstitial pneumonia

Diagnosing IPF cannot be solely based on a lung biopsy consistent with UIP. Appropriate diagnosis should consider the clinical presentation; PFT, laboratory findings (including rheumatologic workup), imaging (especially radiographic patterns), and biopsies. Moreover, the pathologic characteristic of IPF, which is UIP, can be found with other diseases, such as SS. Thus, it is important to make an accurate diagnosis to provide the appropriate treatment available. Patients with ILD associated with SS who have worsening symptoms, PFT, and radiographic abnormalities may be treated with oral prednisone (daily dose: 1 mg/kg).

Conclusion

This case highlights the importance of making an adequate diagnosis of ILD considering that available treatments differ for all possible etiologies other than IPF. This is a true clinical concern taking into account that many patients might be receiving inappropriate therapy for IPF diagnosis, as illustrated in the case study.

Parotid biopsy revealed the presence of inflammatory cells supporting the diagnosis of ILD associated to SS. The patient was discharged home on a tapering dose of steroids. Four months after therapy with steroids, a follow-up chest CT scan without contrast showed a chronic ILD with improved ground-glass opacities (Figure 4). The patient currently is in good health without oxygen supplementation.

Discussion

Diagnosis of SS is challenging, since it may mimic other conditions such as IPF. The most common type of SS-associated ILD is nonspecific interstitial pneumonia (NSIP), although usual interstitial pneumonia (UIP) can be visualized, as in this case study. Usual interstitial pneumonia

Diagnosing IPF cannot be solely based on a lung biopsy consistent with UIP. Appropriate diagnosis should consider the clinical presentation; PFT, laboratory findings (including rheumatologic workup), imaging (especially radiographic patterns), and biopsies. Moreover, the pathologic characteristic of IPF, which is UIP, can be found with other diseases, such as SS. Thus, it is important to make an accurate diagnosis to provide the appropriate treatment available. Patients with ILD associated with SS who have worsening symptoms, PFT, and radiographic abnormalities may be treated with oral prednisone (daily dose: 1 mg/kg).

Conclusion

This case highlights the importance of making an adequate diagnosis of ILD considering that available treatments differ for all possible etiologies other than IPF. This is a true clinical concern taking into account that many patients might be receiving inappropriate therapy for IPF diagnosis, as illustrated in the case study.

Pancreatic panniculitis is a rare disease contributing to widespread fat necrosis in patients with underlying pancreatic disorders. This entity was first described in 1883,¹ but it was not until 1947 that it was reported in the English-language literature.² Patients with pancreatitis infrequently develop extrapancreatic manifestations. It has been estimated that only 2% to 3% of patients worldwide with an underlying pancreatic disease develop cutaneous lesions.³ Patients who develop pancreatic panniculitis typically present with tender, edematous, erythematous to brown, subcutaneous nodules on the lower legs with the tendency for spontaneous ulceration. Lesions tend to exude a viscous, yellow-brown, oily substance that represents liquefactive necrosis of enzymatic fat in subcutaneous tissue. Cutaneous lesions may precede, occur simultaneously, or follow the development of an underlying pancreatic disorder. Rarely, patients may develop inflammatory arthritis secondary to intraosseous fat necrosis, completing the triad of findings diagnostic for panniculitis, pancreatitis, and polyarthritis (PPP) syndrome. Although the underlying pancreatic pathology may vary, roughly 80% of cases worldwide have acute/chronic pancreatitis or pancreatic carcinoma, most commonly acinar cell carcinoma.^4-6 Less common pancreatic disorders include pancreatic pseudocyst, pancreatic divisum, and vascular pancreatic fistulas.⁷ Narváez et al⁸ found that of the 25 cases of PPP syndrome reported in the literature, 68% (17/25) were men, 32% (8/25) were women, 56% (14/25) were younger than 50 years, and 64% (16/25) had a history of prior or current alcohol abuse.

Case Report

A 68-year-old man with a history of hypertension, gastroesophageal reflux disease, chronic pancreatitis of unknown etiology, and arthritis presented to our clinic for evaluation of painful skin nodules on the lower legs of 8 months’ duration, in addition to joint pain and swelling of the metacarpophalangeal (MCP), metatarsophalangeal, and ankle joints. He had a history of numerous hospital admissions over the last 2 years for pancreatitis and was being managed by the rheumatology department for arthritic symptoms.

Physical examination revealed multiple 1- to 4-cm, ill-defined, erythematous to brown, subcutaneous nodules on the bilateral lower legs (Figure 1) and right inferomedial thigh that were tender to palpation. Marked erythema and edema of the MCP and metatarsophalangeal joints (Figure 2) and bilateral ankles were observed. Diffuse 2+ pitting edema was present in the bilateral lower extremities, along with areas of hyperpigmentation overlying resolving lesions.

Laboratory data revealed an elevated lipase level (>16,000 U/L [reference range, 31–186 U/L]), amylase level (>4700 U/L [reference range, 27–131 U/L]), erythrocyte sedimentation rate (94 mm/h [reference range, 0–20 mm/h]), and C-reactive protein level (93.5 mg/L [0.08–3.1 mg/L]). The patient had more than 6 episodes of recurrent idiopathic pancreatitis over the last 2 years, though symptoms of abdominal pain were minimal to nonexistent. Liver function tests and alcohol, calcium, and triglyceride levels all were within reference range. Rheumatoid factor and antinuclear antibodies were negative.

Ultrasonography showed no evidence of cholelithiasis. Computed tomography of the abdomen and pelvis demonstrated a 1.8×1.4-cm hypodense lesion within the pancreatic head with calcifications and mild proximal pancreatic ductal dilatation (Figure 3). However, multiple magnetic resonance cholangiopancreatography examinations and endoscopic ultrasounds with fine-needle aspiration specimens were performed, all negative for malignancy. Computed tomography of the left ankle demonstrated evidence of bony cortical destruction in the lateral aspect of the posterior calcaneus. Bone biopsy specimens demonstrated mild chronic inflammation with no evidence of osteomyelitis. A serum uric acid level was found to be 4.4 mg/dL (reference range, 4.0–8.0 mg/dL) and a joint aspirate demonstrated turbid fluid with lipoid material and no evidence of crystals or organisms on culture. Furthermore, a 4-mm punch biopsy of a nodule on the right leg revealed extensive lobular and septal liquefactive adipocyte necrosis with scattered neutrophils and lymphocytes (Figure 4). Aggregates of fine granular basophilic material were observed with prominent adipocyte degeneration and calcification.

Symptomatic treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) along with intralesional, topical, and oral corticosteroids had proven ineffective in the management of this patient. He was subsequently referred to the surgery department for a pancreaticoduodenectomy (Whipple procedure) with notable improvement in pancreatic enzyme levels, lower leg subcutaneous nodules, and arthritis weeks after surgery.

Comment

A triad of pancreatic panniculitis, pancreatitis, and polyarthritis characterizes a rare entity known as PPP syndrome. Pancreatic panniculitis is a rare form of subcutaneous lobular fat necrosis associated with various underlying pancreatic disorders. Approximately 0.3% to 3.0% of patients with an underlying pancreatic disorder are affected with pancreatic panniculitis.⁹ Pancreatic panniculitis has been found in roughly 2% to 3% of patients with acute or chronic pancreatitis and pancreatic carcinoma, most commonly the acinar cell type.¹⁰ Narváez et al⁸ reported that nearly two-thirds of patients diagnosed with PPP syndrome have minimal to absent abdominal symptoms that often lead to misdiagnosis and affect the overall prognosis of patients with pancreatic disease. Any delay in the diagnosis of PPP syndrome leads to a worse prognosis, with a mortality rate reported to be approximately 24%.⁸ Potts et al⁵ provided a review of 27 patients with pancreatic panniculitis in which all 8 patients with pancreatic carcinoma and 42% (8/19) of patients with pancreatitis died.

Pancreatic panniculitis in the setting of PPP syndrome commonly presents with erythematous to brown, exquisitely tender, edematous, subcutaneous nodules on the lower legs. Lesions can range in size from several millimeters to 5 cm. The subcutaneous nodules may spontaneously ulcerate and exude oily viscous material from the liquefactive necrosis of adipocytes. In approximately 40% of patients, skin lesions are the presenting feature.¹¹ Lesions typically resolve only after the pancreatic inflammation regresses, leaving behind atrophic hyperpigmented scars.³ Other presenting symptoms may include joint pain, pitting edema, and subcutaneous nodules, which can precede the diagnosis by up to 9 months.

The exact pathogenesis of PPP syndrome remains unclear. The most widely recognized hypothesis suggests that pancreatic enzymes (eg, trypsin, amylase, lipase, phospholipase A) released from the damaged pancreas are transported through the bloodstream to distant visceral and soft tissue sites, leading to lipolysis and inflammation to the surrounding subcutis and bone marrow.³ Ferrari et al¹² reported this effect as a product of the accumulation of high levels of free fatty acids within the joint space by the action of lipolytic pancreatic enzymes on adipose cell membranes, resulting in acute arthritis.

Histopathologic findings of pancreatic panniculitis vary based on the acuity of the disease. Acute lesions typically demonstrate lobular and septal panniculitis. Szymanski and Bluefarb¹³ described the pathognomonic histologic findings of focal liquefactive necrosis and anucleate necrotic adipocytes surrounded by a shadowy and thickened cell membrane signifying the characteristic ghost cells. Fine basophilic material also may be seen intermixed with the necrotic adipocytes, representing saponified calcium. A brisk inflammatory infiltrate involving lymphocytes, macrophages, and neutrophils tends to surround the areas of necrotic adipocytes. Chronic lesions often demonstrate a paucity of fat necrosis and ghost cells and more granulomatous infiltrate. Langerhans giant cells, macrophages, and lymphocytes predominate in the subcutaneous fat.

Laboratory findings associated with pancreatic panniculitis may include elevated serum amylase, lipase, and/or trypsin levels. Not all the enzymes have to be elevated simultaneously. On occasion, one enzyme may be within reference range while the others are elevated. Rarely, patients may have an elevated lipase level with no signs of underlying pancreatic disease, which demonstrates that panniculitis does not correlate with the enzyme levels. In all cases of suspected pancreatic panniculitis, a complete laboratory workup is recommended including lipase, amylase, and trypsin serum levels. Eosinophilia may be a prominent finding in patients with pancreatic panniculitis and tends to occur in association with an underlying pancreatic carcinoma. Patients with pancreatic panniculitis associated with pancreatic carcinoma tend to have more severe, diffuse, and persistent subcutaneous nodules that often are refractory to treatment with frequent recurrence. A rare constellation of findings known as Schmid triad is comprised of panniculitis, polyarthritis, and eosinophilia and typically portends a poor prognosis secondary to an underlying pancreatic tumor.¹⁴ Cutaneous nodules may predate the diagnosis of pancreatic carcinoma by several months, thus signifying the need for a high index of suspicion in patients with lower leg subcutaneous nodules.

Joint disease most commonly involves the ankles, knees, wrists, and MCP joints.^5,6,11 It has been suggested that arthritic symptoms are from periarticular fat necrosis or a direct extension from the necrotic subcutaneous tissue to the adjacent joint space.¹⁵ Dahl et al³ reported the composition of joint effusion fluid in 3 patients with PPP syndrome. The aspirate in all 3 patients contained viscous yellow material similar to the necrotic adipose tissue seen draining from subcutaneous nodules. Joint aspirate analysis demonstrated increased concentration of free fatty acids in the joint fluid consistent with severe lipolysis.³

The PPP syndrome acronym may be misleading to physicians, as arthritis is not always polyarticular. Dahl et al³ reported that monoarticular or oligoarticular arthritic symptoms were present in 56% of patients studied. In rare cases, the arthritic symptoms antedated the diagnosis of clinically asymptomatic pancreatic disease. Arthritis can be either symmetric or asymmetric and infrequently follows a chronic course, leading to radiographic lytic lesions and symptoms that often are unresponsive to conventional therapy.¹⁶

Treatment of PPP syndrome is largely supportive, with a focus on correcting the underlying pancreatic disease. It is imperative to identify any complicating factors contributing to high levels of circulating pancreatic enzymes. Pseudocysts must be addressed if discovered in these patients, as they often perpetuate the substantial release of pancreatic enzymes into the serum, leading to characteristic subcutaneous fat necrosis and arthritis. Sepsis also is a concern, likely secondary to bacterial colonization of the ulcerated subcutaneous nodules and compromised skin barrier. Nonsteroidal anti-inflammatory drugs and corticosteroids have been used for symptomatic relief but usually are ineffective and have not been shown to reduce the duration of the disease.^12,16 Octreotide has been utilized and may potentially reduce pancreatic enzyme secretion leading to improvement in cutaneous and musculoskeletal lesions.¹⁷ Plasmapheresis has been used as an adjuvant treatment in patients with persistent hyperamylasemia and hyperlipasemia, but reports are anecdotal. Often reserved for severe disease, cholecystectomy, pancreatic duct removal, and pancreaticoduodenectomy have demonstrated success in the management of chronic pancreatitis and panniculitis. Dahl et al³ reported 2 cases in which cholecystectomy was performed with complete resolution of the skin and pancreatic disease. Our patient was initially treated symptomatically with NSAIDs and corticosteroids but there was no clinical response. The patient eventually underwent a pancreaticoduodenectomy 9 months after the onset of symptoms with complete resolution of joint pain and swelling, greater than 50% resolution of his lower leg subcutaneous nodules, and remarkable reduction in amylase and lipase levels on 1-month follow-up.

Conclusion

Panniculitis, pancreatitis, and polyarthritis syndrome is a rare diagnosis characterized by a triad of pancreatic panniculitis, pancreatitis, and polyarthritis. Adjuvant therapies for PPP syndrome, such as NSAIDs, corticosteroids, plasmapheresis, and octreotide, have been used with equivocal results, but definitive treatment requires correction of the primary pancreatic disorder. More importantly, many pancreatic diseases can cause pancreatic panniculitis, but extensive, refractory, or ulcerated cases could be an early indicator of an occult pancreatic malignancy and should prompt early evaluation with a multidisciplinary approach. This approach should incorporate management from dermatology, internal medicine, rheumatology, gastroenterology, surgery, and primary care.

Sepsis also is a concern, likely secondary to bacterial colonization of the ulcerated subcutaneous nodules and compromised skin barrier. Nonsteroidal anti-inflammatory drugs and corticosteroids have been used for symptomatic relief but usually are ineffective and have not been shown to reduce the duration of the disease.^12,16 Octreotide has been utilized and may potentially reduce pancreatic enzyme secretion leading to improvement in cutaneous and musculoskeletal lesions.¹⁷ Plasmapheresis has been used as an adjuvant treatment in patients with persistent hyperamylasemia and hyperlipasemia, but reports are anecdotal. Often reserved for severe disease, cholecystectomy, pancreatic duct removal, and pancreaticoduodenectomy have demonstrated success in the management of chronic pancreatitis and panniculitis. Dahl et al³ reported 2 cases in which cholecystectomy was performed with complete resolution of the skin and pancreatic disease. Our patient was initially treated symptomatically with NSAIDs and corticosteroids but there was no clinical response. The patient eventually underwent a pancreaticoduodenectomy 9 months after the onset of symptoms with complete resolution of joint pain and swelling, greater than 50% resolution of his lower leg subcutaneous nodules, and remarkable reduction in amylase and lipase levels on 1-month follow-up.

Conclusion

Panniculitis, pancreatitis, and polyarthritis syndrome is a rare diagnosis characterized by a triad of pancreatic panniculitis, pancreatitis, and polyarthritis. Adjuvant therapies for PPP syndrome, such as NSAIDs, corticosteroids, plasmapheresis, and octreotide, have been used with equivocal results, but definitive treatment requires correction of the primary pancreatic disorder. More importantly, many pancreatic diseases can cause pancreatic panniculitis, but extensive, refractory, or ulcerated cases could be an early indicator of an occult pancreatic malignancy and should prompt early evaluation with a multidisciplinary approach. This approach should incorporate management from dermatology, internal medicine, rheumatology, gastroenterology, surgery, and primary care.

Case Presentation. A 23-year-old male U.S. Army veteran with a history of alcohol use disorder and posttraumatic stress disorder (PTSD) presented to the VA Boston Healthcare System (VABHS) West Roxbury campus emergency department (ED) with epigastric abdominal pain in the setting of consuming alcohol. The patient had served in the infantry in Afghanistan during Operation Enduring Freedom. He consumed up to 12 alcoholic drinks per day (both beer and hard liquor) for the past 3 years and had been hospitalized 3 times previously; twice for alcohol detoxification and once for PTSD. He is a former tobacco smoker with fewer than 5 pack-years, he uses marijuana often and does not use IV drugs. In the ED, his physical examination was notable for a heart rate of 130 beats per minute and blood pressure of 161/111 mm Hg. He was alert and oriented and had a mild tremor. The patient was diaphoretic with dry mucous membranes, tenderness to palpation in the epigastrium, and abdominal guarding. A computed tomography (CT) scan of the abdomen revealed acute pancreatitis without necrosis. The patient received 1 L of normal saline and was admitted to the medical ward for presumed alcoholic pancreatitis.

► Rahul Ganatra, MD, MPH, Chief Medical Resident, VABHS and Beth Israel Deaconess Medical Center. Dr. Weber, we care for many young people who drink more than they should and almost none of them end up with alcoholic pancreatitis. What are the relevant risk factors that make individuals like this patient more susceptible to alcoholic pancreatitis?

►Horst Christian Weber, MD, Gastroenterology Service, VABHS, and Assistant Professor of Medicine, Boston University School of Medicine. While we don’t have a good understanding of the precise mechanism of alcoholic pancreatitis, we do know that in the U.S., alcohol consumption is responsible for about one-third of all cases.¹ Acute pancreatitis in general may present with a wide range of disease severity. It is the most common cause of gastrointestinal-related hospitalization,² and the mortality of hospital inpatients with pancreatitis is about 5%.^3,4 Therefore, acute pancreatitis represents a prevalent condition with a critical impact on morbidity and mortality. Alcoholic pancreatitis typically occurs after many years of heavy alcohol use, not after a single drinking

► Dr. Ganatra. At this point, the chemistry laboratory paged the admitting resident with the notification that the patient’s blood was grossly lipemic. Ultracentrifugation was performed to separate the lipid layer and his laboratory values result (Table). Notable abnormalities included polycythemia with a hemoglobin of 17.4 g/dL, hyponatremia with a sodium of 129 mmol/L, normal renal function, elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (AST 258 IU/L and ALT 153 IU/L, respectively), hyperbilirubinemia with a total bilirubin of 2.7 mg/dL, and a serum alcohol level of 147 mg/dL. Due to anticipated requirement for a higher level of care, the patient was transferred to the Medical Intensive Care Unit (MICU).

Dr. Breu, can you help us interpret this patient’s numerous laboratory abnormalities? Without yet having the triglyceride level available, how does the fact that the patient’s blood was lipemic affect our interpretation of his labs? What further workup is warranted?

► Anthony Breu, MD, Medical Service, VABHS, Assistant Professor of Medicine, Harvard Medical School. First, the positive alcohol level confirms a recent ingestion. Second, he has elevated transaminases with the AST greater than the ALT, which is consistent with alcoholic liver disease. While the initial assumption is that this patient has alcohol-induced pancreatitis, the elevations in bilirubin and alkaline phosphatase may suggest gallstone pancreatitis, and the lipemic appearing serum could suggest triglyceride-mediated pancreatitis. If the patient does have elevated triglyceride levels, the sodium level may indicate pseudohyponatremia, a laboratory artifact seen if a dilution step is used. To further evaluate the patient, I would obtain a triglyceride level and a right upper quadrant ultrasound. Direct ion-selective electrode analysis of the sodium level can be done with a device used to measure blood gases to exclude pseudohyponatremia.

► Dr. Ganatra. A right upper quadrant ultrasound was obtained in the MICU, which showed hepatic steatosis and hepatomegaly to 19 cm, but no evidence of biliary obstruction by stones or sludge. The common bile duct measured 3.2 mm in diameter. A triglyceride level returned above assay at > 3,392 mg/dL. A review of the medical record revealed a triglyceride level of 105 mg/dL 16 months prior. The Gastroenterology Department was consulted.

Dr. Weber, we now have 2 etiologies for pancreatitis in this patient: alcohol and hypertriglyceridemia. How do each cause pancreatitis? Is it possible to determine in this case which one is the more likely driver?

► Dr. Weber. The mechanism for alcohol-induced pancreatitis is not fully known, but there are several hypotheses. One is that alcohol may increase the synthesis or activation of pancreatic digestive enzymes.⁶ Another is that metabolites of alcohol are directly toxic to the pancreas.⁶ Based on the epidemiologic observation that alcoholic pancreatitis usually happens in long-standing users, all we can say is that it is not very likely to be the effect of an acute insult. For hypertriglyceridemic pancreatitis, we believe the injury is due to the toxic effect of free fatty acids in the pancreas liberated by lipolysis of triglycerides by pancreatic lipases. Higher triglycerides are associated with higher risk, suggesting a dose-response relationship: This risk is not greatly increased until triglycerides exceed 500 mg/dL; above 1,000 mg/dL, the risk is about 5%, and above 2,000 mg/dL, the risk is between 10% and 20%.⁷ In summary, we cannot really determine whether the alcohol or the triglycerides are the main cause of his pancreatitis, but given his markedly elevated triglycerides, he should be treated for hypertriglyceridemic pancreatitis.

►Dr. Ganatra. Dr. Breu, regardless of the underlying etiology, this patient requires treatment. What does the literature suggest as the best course of action regarding crystalloid administration in patients with acute pancreatitis?

►Dr. Breu. There are 2 issues to discuss regarding IV fluids in acute pancreatitis: choice of crystalloid and rate of administration. For the choice of IV fluid, lactated Ringer solution (LR) may be preferred over normal saline (NS). There are both pathophysiologic and evidence-based rationales for this choice. As Dr. Weber alluded to, trypsinogen activation is an important step in the pathogenesis of acute pancreatitis and requires a low pH compartment. As most clinicians have experienced, NS may cause a metabolic acidosis; however, the use of LR may mitigate this. A 2011 randomized clinical trial showed that patients who received LR had less systemic inflammatory response syndrome (SIRS) and lower C-reactive protein (CRP) levels at 24 hours compared with patients who received NS.⁸ While these are surrogate outcomes, they, along with the theoretical basis, suggest LR is preferred.

Regarding rate, the key is fast and early.⁹ In my experience, internists often underdose IV rehydration within the first 12 to 24 hours, fail to change the rate based on clinical response, and leave patients on high rates too long. In a patient like this, a rate of 350 cc/h is a reasonable place to start. But, one must reassess response (ie, ensure there is a decrease in hematocrit and/or blood urea nitrogen) every 6 hours and increase the rate as needed. After the first 24 to 48 hours have passed, the rate should be lowered.

►Dr. Ganatra. The patient received 2 mg of IV hydromorphone and a 2 L bolus of LR. This was followed by a continuous infusion of LR at 200 cc/h. Dr. Weber, apart from the standard therapies for pancreatitis, what are our treatment options in hypertriglyceridemic pancreatitis?

►Dr. Weber. In the acute setting, IV insulin with or without dextrose is the most extensively studied therapy. Insulin rapidly decreases triglyceride levels by activating lipoprotein lipase and inhibiting hormone- sensitive lipase. The net effect is reduction in serum triglycerides available to be hydrolyzed to free fatty acids in the pancreas.⁷ For severe cases (ie, where acute pancreatitis is accompanied by hypocalcemia, lactic acidosis or a markedly elevated lipase), apheresis with therapeutic plasma exchange to more rapidly reduce triglyceride concentration is the preferred therapy. The goal is to reduce triglycerides to levels

►Dr. Ganatra. Due to the possibility that the patient would require apheresis, which was not available at the VABHS West Roxbury campus, the patient was transferred to an affiliate hospital. The patient was started on 10% dextrose at 300 cc/h and an IV insulin infusion. His triglycerides fell to < 500 mg/dL over the subsequent 48 hours, and ultimately, apheresis was not required. Enteral nutrition by nasogastric (NG) tube was initiated on hospital day 6. The patient’s hospital course was notable for acute respiratory distress syndrome that required intubation for 7 days, hyperbilirubinemia (with a peak bilirubin of 10.5 mg/dL), acute kidney injury (with a peak creatinine 4.7 mg/dL), fever without an identified infectious source, alcohol withdrawal syndrome that required phenobarbital, and delirium. Nine days later, he was transferred back to the VABHS West Roxbury campus. His condition stabilized, and he was transferred to the medical floor. On hospital day 14, the patient’s mental status improved, and he began tolerating oral nutrition.

Dr. Breu, over the years, the standard of care regarding when to start enteral nutrition in pancreatitis has changed considerably. This patient received enteral nutrition via NG tube but also had periods of being NPO (nothing by mouth) for up to 6 days. What is the current best practice for timing of initiating enteral nutrition in acute pancreatitis?

►Dr. Breu. It is true that the standard of care has changed and continues to evolve. Many decades ago, patients with acute pancreatitis would routinely undergo NG tube suction to reduce delivery of gastric contents to the duodenum, thereby decreasing pancreas activation, allowing it to rest.¹¹ The NG tube also allowed for decompression of any ileus that had formed. Beginning in the 1970s, several clinical trials were performed, showing that NG tube suction was no better than simply making the patient NPO.^12,13 More recently, we have begun to move toward earlier feeding. Again, there is a pathophysiologic rationale (bowel rest is associated with intestinal atrophy, predisposing to bacterial translocation and resulting infectious complications) and increasing evidence supporting this practice.⁹ Even in severe pancreatitis, hunger may be used to initiate oral intake.¹⁴

►Dr. Weber. Organ failure in the acute setting can occur due to activation of cytokine cascades and the systemic inflammatory response syndrome and is described by clinical and radiologic criteria called the Atlanta Classification.¹⁵ Apart from organ failure, the most serious complications of acute pancreatitis are necrosis of pancreatic tissue leading to walled-off pancreatic necrosis and the formation of peripancreatic fluid collections and pseudocysts, which occur in about 15% of patients with acute pancreatitis. These complications are serious because they can become infected, which portends a higher mortality and in some cases require surgical resection.

Other complications of acute pancreatitis include pseudoaneurysm formation, which is when a vessel bleeds into a pancreatic pseudocyst, and thromboses of the splenic, portal, or mesenteric veins. Thrombotic complications may occur in up to half of patients with pancreatic necrosis but are uncommon without some degree of necrosis.¹⁶ No necrosis was noted on this patient’s initial CT scan, so the probability of thrombosis is low. Also, as it takes several weeks for pseudocyst formation to occur, a bleeding pseudoaneurysm is unlikely at this early stage. Therefore, a complication of pancreatitis is unlikely in this patient, and evaluation for other causes of abdominal pain should be considered.

►Dr. Ganatra. A noncontrast CT of the abdomen and pelvis was obtained and revealed no evidence of complications or other acute pathology. His pain was managed conservatively, and hemoglobin remained stable. Over the next 5 days, the patient’s symptoms gradually resolved, his oral intake improved, and he was discharged home on gemfibrozil 600 mg twice daily 19 days after admission. He declined psychiatry follow-up for his PTSD, and after discharge he did not keep his scheduled gastroenterology (GI) follow-up appointment. Four months later, the patient presented again with epigastric abdominal pain similar to his initial presentation. The patient had resumed drinking, stating that “alcohol is the only thing that helps [with the PTSD].” He had not been taking the gemfibrozil. He was admitted with a recurrent episode of pancreatitis; however, his triglycerides on admission were 119 mg/dL.

Dr. Weber, this patient’s triglycerides declined rapidly over a period of just 4 months with questionable adherence to gemfibrozil. However, he was admitted again with another episode of pancreatitis, this time in the setting of alcohol use alone without markedly elevated triglycerides. What do we know about recurrence risk for pancreatitis? Are some etiologies of pancreatitis more likely to present with recurrent attacks than are others?

►Dr. Weber. The rate of recurrence following an episode of acute pancreatitis varies according to the cause, but in general, about 20% to 30% of patients will experience a recurrence, and 5% to 10% will go on to develop chronic pancreatitis.¹⁷ Alcoholic pancreatitis does carry a higher risk of recurrence than pancreatitis due to other causes; the risk is as high as 50%. Not surprisingly, recurrence of acute pancreatitis increases risk for development of chronic pancreatitis. As this patient is a smoker, it is worth noting that smoking potentiates pancreatic damage from alcohol and increases the risk for both recurrent and chronic pancreatitis.⁵

►Dr. Ganatra. The patient was treated with IV hydromorphone and IV LR at 350 cc/h. Oral nutrition was begun immediately. He manifested no organ dysfunction, and his symptoms improved over the course of 48 hours. He was discharged home with psychiatry and GI follow-up scheduled. Dr. Breu and Dr. Weber, how should we counsel this patient to reduce his risk of recurrent attacks of pancreatitis in the future, and what options do we have for pharmacotherapy to decrease his risk?

►Dr. Breu. I’ll let Dr. Weber comment on mitigating the risk of hypertriglyceride-induced pancreatitis and reserve my comments to pharmacotherapy in alcohol use disorder. This patient may be a candidate for naltrexone therapy, either in oral or intramuscular formulations. Both have been showed to reduce the risk of returning to heavy drinking and may be particularly beneficial in those with a family history.^18,19 Acamprosate is also an option.

►Dr. Weber. Data on recurrence risk in hypertriglyceridemic pancreatitis are limited, but there are case reports suggesting that a fatty diet and alcohol use are implicated in recurrence.²⁰ I would counsel the patient on lifestyle modifications that are known to reduce this risk. I agree with Dr. Breu that devoting our efforts to helping him reduce or eliminate his alcohol consumption is the single most important thing we can do to reduce his risk for recurrent attacks. Since the patient reports that he drinks alcohol in order to cope with his PTSD, establishing care with a mental health provider to address this is of the utmost importance. In addition, smoking cessation and promoting medication adherence with gemfibrozil will also reduce risk for future episodes, but continued alcohol use is his strongest risk factor.

►Dr. Ganatra. After discharge, the patient engaged with outpatient psychiatry and GI. He still reports feeling that alcohol is the only thing that alleviates his PTSD and anxiety symptoms. He is not currently interested in pharmacotherapy for cessation of alcohol use.

While we don’t have a good understanding of the precise mechanism of alcoholic pancreatitis, we do know that in the U.S., alcohol consumption is responsible for about one-third of all cases.¹ Acute pancreatitis in general may present with a wide range of disease severity. It is the most common cause of gastrointestinal-related hospitalization,² and the mortality of hospital inpatients with pancreatitis is about 5%.^3,4 Therefore, acute pancreatitis represents a prevalent condition with a critical impact on morbidity and mortality. Alcoholic pancreatitis typically occurs after many years of heavy alcohol use, not after a single drinking

► Dr. Ganatra. At this point, the chemistry laboratory paged the admitting resident with the notification that the patient’s blood was grossly lipemic. Ultracentrifugation was performed to separate the lipid layer and his laboratory values result (Table). Notable abnormalities included polycythemia with a hemoglobin of 17.4 g/dL, hyponatremia with a sodium of 129 mmol/L, normal renal function, elevated aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (AST 258 IU/L and ALT 153 IU/L, respectively), hyperbilirubinemia with a total bilirubin of 2.7 mg/dL, and a serum alcohol level of 147 mg/dL. Due to anticipated requirement for a higher level of care, the patient was transferred to the Medical Intensive Care Unit (MICU).

Dr. Breu, can you help us interpret this patient’s numerous laboratory abnormalities? Without yet having the triglyceride level available, how does the fact that the patient’s blood was lipemic affect our interpretation of his labs? What further workup is warranted?

► Anthony Breu, MD, Medical Service, VABHS, Assistant Professor of Medicine, Harvard Medical School. First, the positive alcohol level confirms a recent ingestion. Second, he has elevated transaminases with the AST greater than the ALT, which is consistent with alcoholic liver disease. While the initial assumption is that this patient has alcohol-induced pancreatitis, the elevations in bilirubin and alkaline phosphatase may suggest gallstone pancreatitis, and the lipemic appearing serum could suggest triglyceride-mediated pancreatitis. If the patient does have elevated triglyceride levels, the sodium level may indicate pseudohyponatremia, a laboratory artifact seen if a dilution step is used. To further evaluate the patient, I would obtain a triglyceride level and a right upper quadrant ultrasound. Direct ion-selective electrode analysis of the sodium level can be done with a device used to measure blood gases to exclude pseudohyponatremia.

► Dr. Ganatra. A right upper quadrant ultrasound was obtained in the MICU, which showed hepatic steatosis and hepatomegaly to 19 cm, but no evidence of biliary obstruction by stones or sludge. The common bile duct measured 3.2 mm in diameter. A triglyceride level returned above assay at > 3,392 mg/dL. A review of the medical record revealed a triglyceride level of 105 mg/dL 16 months prior. The Gastroenterology Department was consulted.

Dr. Weber, we now have 2 etiologies for pancreatitis in this patient: alcohol and hypertriglyceridemia. How do each cause pancreatitis? Is it possible to determine in this case which one is the more likely driver?

► Dr. Weber. The mechanism for alcohol-induced pancreatitis is not fully known, but there are several hypotheses. One is that alcohol may increase the synthesis or activation of pancreatic digestive enzymes.⁶ Another is that metabolites of alcohol are directly toxic to the pancreas.⁶ Based on the epidemiologic observation that alcoholic pancreatitis usually happens in long-standing users, all we can say is that it is not very likely to be the effect of an acute insult. For hypertriglyceridemic pancreatitis, we believe the injury is due to the toxic effect of free fatty acids in the pancreas liberated by lipolysis of triglycerides by pancreatic lipases. Higher triglycerides are associated with higher risk, suggesting a dose-response relationship: This risk is not greatly increased until triglycerides exceed 500 mg/dL; above 1,000 mg/dL, the risk is about 5%, and above 2,000 mg/dL, the risk is between 10% and 20%.⁷ In summary, we cannot really determine whether the alcohol or the triglycerides are the main cause of his pancreatitis, but given his markedly elevated triglycerides, he should be treated for hypertriglyceridemic pancreatitis.

►Dr. Ganatra. Dr. Breu, regardless of the underlying etiology, this patient requires treatment. What does the literature suggest as the best course of action regarding crystalloid administration in patients with acute pancreatitis?

►Dr. Breu. There are 2 issues to discuss regarding IV fluids in acute pancreatitis: choice of crystalloid and rate of administration. For the choice of IV fluid, lactated Ringer solution (LR) may be preferred over normal saline (NS). There are both pathophysiologic and evidence-based rationales for this choice. As Dr. Weber alluded to, trypsinogen activation is an important step in the pathogenesis of acute pancreatitis and requires a low pH compartment. As most clinicians have experienced, NS may cause a metabolic acidosis; however, the use of LR may mitigate this. A 2011 randomized clinical trial showed that patients who received LR had less systemic inflammatory response syndrome (SIRS) and lower C-reactive protein (CRP) levels at 24 hours compared with patients who received NS.⁸ While these are surrogate outcomes, they, along with the theoretical basis, suggest LR is preferred.

Regarding rate, the key is fast and early.⁹ In my experience, internists often underdose IV rehydration within the first 12 to 24 hours, fail to change the rate based on clinical response, and leave patients on high rates too long. In a patient like this, a rate of 350 cc/h is a reasonable place to start. But, one must reassess response (ie, ensure there is a decrease in hematocrit and/or blood urea nitrogen) every 6 hours and increase the rate as needed. After the first 24 to 48 hours have passed, the rate should be lowered.

►Dr. Ganatra. The patient received 2 mg of IV hydromorphone and a 2 L bolus of LR. This was followed by a continuous infusion of LR at 200 cc/h. Dr. Weber, apart from the standard therapies for pancreatitis, what are our treatment options in hypertriglyceridemic pancreatitis?

►Dr. Weber. In the acute setting, IV insulin with or without dextrose is the most extensively studied therapy. Insulin rapidly decreases triglyceride levels by activating lipoprotein lipase and inhibiting hormone- sensitive lipase. The net effect is reduction in serum triglycerides available to be hydrolyzed to free fatty acids in the pancreas.⁷ For severe cases (ie, where acute pancreatitis is accompanied by hypocalcemia, lactic acidosis or a markedly elevated lipase), apheresis with therapeutic plasma exchange to more rapidly reduce triglyceride concentration is the preferred therapy. The goal is to reduce triglycerides to levels

►Dr. Ganatra. Due to the possibility that the patient would require apheresis, which was not available at the VABHS West Roxbury campus, the patient was transferred to an affiliate hospital. The patient was started on 10% dextrose at 300 cc/h and an IV insulin infusion. His triglycerides fell to < 500 mg/dL over the subsequent 48 hours, and ultimately, apheresis was not required. Enteral nutrition by nasogastric (NG) tube was initiated on hospital day 6. The patient’s hospital course was notable for acute respiratory distress syndrome that required intubation for 7 days, hyperbilirubinemia (with a peak bilirubin of 10.5 mg/dL), acute kidney injury (with a peak creatinine 4.7 mg/dL), fever without an identified infectious source, alcohol withdrawal syndrome that required phenobarbital, and delirium. Nine days later, he was transferred back to the VABHS West Roxbury campus. His condition stabilized, and he was transferred to the medical floor. On hospital day 14, the patient’s mental status improved, and he began tolerating oral nutrition.

Dr. Breu, over the years, the standard of care regarding when to start enteral nutrition in pancreatitis has changed considerably. This patient received enteral nutrition via NG tube but also had periods of being NPO (nothing by mouth) for up to 6 days. What is the current best practice for timing of initiating enteral nutrition in acute pancreatitis?

►Dr. Breu. It is true that the standard of care has changed and continues to evolve. Many decades ago, patients with acute pancreatitis would routinely undergo NG tube suction to reduce delivery of gastric contents to the duodenum, thereby decreasing pancreas activation, allowing it to rest.¹¹ The NG tube also allowed for decompression of any ileus that had formed. Beginning in the 1970s, several clinical trials were performed, showing that NG tube suction was no better than simply making the patient NPO.^12,13 More recently, we have begun to move toward earlier feeding. Again, there is a pathophysiologic rationale (bowel rest is associated with intestinal atrophy, predisposing to bacterial translocation and resulting infectious complications) and increasing evidence supporting this practice.⁹ Even in severe pancreatitis, hunger may be used to initiate oral intake.¹⁴

►Dr. Weber. Organ failure in the acute setting can occur due to activation of cytokine cascades and the systemic inflammatory response syndrome and is described by clinical and radiologic criteria called the Atlanta Classification.¹⁵ Apart from organ failure, the most serious complications of acute pancreatitis are necrosis of pancreatic tissue leading to walled-off pancreatic necrosis and the formation of peripancreatic fluid collections and pseudocysts, which occur in about 15% of patients with acute pancreatitis. These complications are serious because they can become infected, which portends a higher mortality and in some cases require surgical resection.

Other complications of acute pancreatitis include pseudoaneurysm formation, which is when a vessel bleeds into a pancreatic pseudocyst, and thromboses of the splenic, portal, or mesenteric veins. Thrombotic complications may occur in up to half of patients with pancreatic necrosis but are uncommon without some degree of necrosis.¹⁶ No necrosis was noted on this patient’s initial CT scan, so the probability of thrombosis is low. Also, as it takes several weeks for pseudocyst formation to occur, a bleeding pseudoaneurysm is unlikely at this early stage. Therefore, a complication of pancreatitis is unlikely in this patient, and evaluation for other causes of abdominal pain should be considered.

►Dr. Ganatra. A noncontrast CT of the abdomen and pelvis was obtained and revealed no evidence of complications or other acute pathology. His pain was managed conservatively, and hemoglobin remained stable. Over the next 5 days, the patient’s symptoms gradually resolved, his oral intake improved, and he was discharged home on gemfibrozil 600 mg twice daily 19 days after admission. He declined psychiatry follow-up for his PTSD, and after discharge he did not keep his scheduled gastroenterology (GI) follow-up appointment. Four months later, the patient presented again with epigastric abdominal pain similar to his initial presentation. The patient had resumed drinking, stating that “alcohol is the only thing that helps [with the PTSD].” He had not been taking the gemfibrozil. He was admitted with a recurrent episode of pancreatitis; however, his triglycerides on admission were 119 mg/dL.

Dr. Weber, this patient’s triglycerides declined rapidly over a period of just 4 months with questionable adherence to gemfibrozil. However, he was admitted again with another episode of pancreatitis, this time in the setting of alcohol use alone without markedly elevated triglycerides. What do we know about recurrence risk for pancreatitis? Are some etiologies of pancreatitis more likely to present with recurrent attacks than are others?

►Dr. Weber. The rate of recurrence following an episode of acute pancreatitis varies according to the cause, but in general, about 20% to 30% of patients will experience a recurrence, and 5% to 10% will go on to develop chronic pancreatitis.¹⁷ Alcoholic pancreatitis does carry a higher risk of recurrence than pancreatitis due to other causes; the risk is as high as 50%. Not surprisingly, recurrence of acute pancreatitis increases risk for development of chronic pancreatitis. As this patient is a smoker, it is worth noting that smoking potentiates pancreatic damage from alcohol and increases the risk for both recurrent and chronic pancreatitis.⁵

►Dr. Ganatra. The patient was treated with IV hydromorphone and IV LR at 350 cc/h. Oral nutrition was begun immediately. He manifested no organ dysfunction, and his symptoms improved over the course of 48 hours. He was discharged home with psychiatry and GI follow-up scheduled. Dr. Breu and Dr. Weber, how should we counsel this patient to reduce his risk of recurrent attacks of pancreatitis in the future, and what options do we have for pharmacotherapy to decrease his risk?

►Dr. Breu. I’ll let Dr. Weber comment on mitigating the risk of hypertriglyceride-induced pancreatitis and reserve my comments to pharmacotherapy in alcohol use disorder. This patient may be a candidate for naltrexone therapy, either in oral or intramuscular formulations. Both have been showed to reduce the risk of returning to heavy drinking and may be particularly beneficial in those with a family history.^18,19 Acamprosate is also an option.

►Dr. Weber. Data on recurrence risk in hypertriglyceridemic pancreatitis are limited, but there are case reports suggesting that a fatty diet and alcohol use are implicated in recurrence.²⁰ I would counsel the patient on lifestyle modifications that are known to reduce this risk. I agree with Dr. Breu that devoting our efforts to helping him reduce or eliminate his alcohol consumption is the single most important thing we can do to reduce his risk for recurrent attacks. Since the patient reports that he drinks alcohol in order to cope with his PTSD, establishing care with a mental health provider to address this is of the utmost importance. In addition, smoking cessation and promoting medication adherence with gemfibrozil will also reduce risk for future episodes, but continued alcohol use is his strongest risk factor.

►Dr. Ganatra. After discharge, the patient engaged with outpatient psychiatry and GI. He still reports feeling that alcohol is the only thing that alleviates his PTSD and anxiety symptoms. He is not currently interested in pharmacotherapy for cessation of alcohol use.

Molluscum contagiosum (MC) is a double-stranded DNA virus of the Poxviridae family, which commonly infects human keratinocytes resulting in small, umbilicated, flesh-colored papules. The greatest incidence of MC is seen in the pediatric population and sexually active young adults, and it is considered a self-limited disease in immunocompetent individuals.¹ With the emergence of the human immunodeficiency virus (HIV) and subsequent AIDS epidemic in the 1980s, a new population of immunocompromised individuals has been observed to be increasingly susceptible to MC with an atypical clinical presentation and a recalcitrant disease course.² Although the increased prevalence of MC in the HIV population has been well-documented, it has been observed in other disease states or iatrogenically induced immunosuppression due to a deficiency in function or absolute number of T lymphocytes.

We present a case of a patient with long-standing psoriasis on biologic therapy who presented with MC with a subsequent workup that revealed AIDS. This case reiterates the importance of MC as a potential indicator of underlying immunosuppression. We review the literature to evaluate the occurrence of MC in immunosuppressed patients.

Case Report

A 33-year-old man initially presented for evaluation of severe plaque-type psoriasis associated with pain, erythema, and swelling of the joints of the hands of 10 years’ duration. He was started on methotrexate 5 mg weekly and topical corticosteroids but was unable to tolerate methotrexate due to headaches. He also had difficulty affording topical medications and adjunctive phototherapy. The patient was sporadically seen in follow-up with persistence of psoriatic plaques involving up to 60% body surface area (BSA) with the only treatment consisting of occasional topical steroids. Five years later, the patient was restarted on methotrexate 5 to 7.5 mg weekly, which resulted in moderate improvement. However, because of persistent elevation of liver enzymes, this treatment was stopped. Several months later he was evaluated for treatment with a biologic agent, and after a negative tuberculin skin test, he began treatment with etanercept 50 mg subcutaneous injection twice weekly, which provided notable improvement and allowed for reduction of dose frequency to once weekly.

At follow-up 1 year later, the patient had continued improvement of psoriasis with approximately 30% BSA on a treatment regimen of etanercept 50 mg weekly injection and topical corticosteroids. However, on physical examination, there were multiple small semitranslucent papules with telangiectases on the chest and upper back (Figure 1). Biopsy of a representative papule on the chest revealed MC (Figure 2). The patient was subsequently advised to stop etanercept and to return immediately to the clinic for HIV testing. He returned for follow-up 3 months later with pronounced worsening of disease and a new onset of blurred vision of the right eye. Cutaneous examination revealed numerous large erythematous plaques with superficial scale and cerebriform surface on the chest, back, abdomen, and upper and lower extremities involving 80% BSA (Figure 3). Biopsy of a plaque demonstrated psoriasiform dermatitis with neutrophils and parakeratosis consistent with psoriasis. Extensive blood work was notable for reactive HIV antibody and lymphopenia, CD4 lymphocyte count of 60 cells/mm³, and an HIV viral load of 247,000 copies/mL, meeting diagnostic criteria for AIDS. Additionally, ophthalmologic evaluation revealed toxoplasma retinitis. Upon initiation of highly active antiretroviral therapy (HAART) and continued use of topical corticosteroids, the patient experienced notable improvement of disease severity with approximately 20% BSA.

Comment

Molluscum contagiosum is a common skin infection. Among patients with HIV and other types of impaired cellular immunity, the prevalence of MC is estimated to be as high as 20%.³ The MC poxvirus survives and proliferates within the epidermis by interfering with tumor necrosis factor–induced apoptosis of virally infected cells; therefore, intact cell-mediated immunity is an important component of prevention and clearance of poxvirus infections. In immunocompromised patients, the presentation of MC varies widely, and the disease is often difficult to eradicate. This review will highlight the prevalence, presentation, and treatment of MC in the context of immunosuppressed states.

HIV/AIDS
Molluscum contagiosum in HIV-positive patients was first recognized in 1983,² and its prevalence is estimated to range from 5% to 18% in AIDS patients.³ Molluscum contagiosum is a clinical sign of HIV progression, and its incidence appears to increase with reduced immune function (ie, a CD4 cell count <200/mm³).³ In a study of 456 patients with HIV-associated skin disorders, the majority of patients with MC had notable immunosuppression with a median survival time of 12 months. Thus, MC was not an independent prognostic marker but a clinical indicator of markedly reduced immune status.⁴

Molluscum contagiosum is transmitted in both sexual and nonsexual patterns in HIV-positive individuals, with the distribution of the latter involving primarily the face and neck. Although it may present with typical umbilicated papules, MC has a wide range of atypical clinical presentations in patients with AIDS that can make it difficult to diagnose. Complicated cases of eyelid MC have been reported in advanced HIV in both adults and children, resulting in obstruction of vision due to large lesions (up to 2 cm) or hundreds of confluent lesions.⁵ Giant MC, which appears as large exophytic nodules, is another presentation that has been frequently described in patients with advanced HIV. In these patients, the lesions often are too voluminous for conservative therapy and require excision.⁶ Atypical MC lesions also can resemble other dermatologic conditions, including condyloma acuminatum,⁷ nevus sebaceous of Jadassohn, ecthyma,⁸ and cutaneous horns,^9,10 as well as other bacterial and fungal infections in HIV-positive patients, such as cutaneous Cryptococcus neoformans,^11,12 disseminated histoplasmosis,¹³ and infections caused by Penicillium marneffei¹⁴ and Bartonella henselae.¹⁵ In most cases of MC in HIV-positive patients, diagnosis is dependent on the examination of biopsy specimens, which maintain the same histopathologic features regardless of immune status.

The management of MC in patients with HIV/AIDS is difficult. Molluscum contagiosum has shown no evidence of spontaneous resolution in patients with HIV, and treatment with one modality is often insufficient. Treatment is most successful when a combination approach is utilized with destructive procedures (eg, curettage, cryosurgery) and adjunctive agents (eg, retinoids, cantharidin, trichloroacetic acid). Imiquimod and cidofovir have been used off label for MC in AIDS patients.¹⁶ Imiquimod, which is used to treat genital warts, another cutaneous viral infection seen in patients with HIV, has demonstrated efficacy in treating MC.¹⁶ In a randomized controlled trial comparing imiquimod cream 5% to cryotherapy for MC in healthy children, imiquimod was slow acting but better suited than cryotherapy for patients with eruptions of many small lesions.¹⁷ For HIV patients, numerous reports have described successful treatment of disseminated or recalcitrant MC with topical imiquimod.^18-20 Cidofovir, an antiviral used to treat cytomegalovirus retinitis in patients with AIDS, is a promising antiviral agent against the poxvirus family. In a study of viral DNA polymerase genes of MC virus, cidofovir inhibited MC virus DNA polymerase activity.²¹ It has been used in both topical (1% to 3%) and intravenous form to successfully treat recalcitrant and exuberant giant MC.^6,22 However, the use of cidofovir is limited by its high costs, especially when compounded into a topical formulation.²³

From a systemic standpoint, numerous reports have shown that treating the underlying HIV by optimizing HAART is the most important first step in clearing MC.^24-27 However, a special concern regarding the initiation of HAART in patients with MC as well as a markedly impaired immune function is the development of an inflammatory reaction called immune reconstitution inflammatory syndrome (IRIS). This reaction is thought to be a result of immune recovery in severely immunosuppressed patients. During the initial phase of reconstitution when CD4 lymphocyte counts rise and viral load decreases, IRIS occurs due to an inflammatory reaction to microbial and autoimmune antigens, leading to temporary clinical deterioration.²⁸ The incidence has been reported in up to 25% of patients starting HAART, and 52% to 78% of IRIS cases involve dermatologic manifestations such as varicella-zoster virus, cytomegalovirus infections, genital warts, and MC.^29,30 In a cohort study of 199 patients, 2% of patients developed MC within 6 months of initiating HAART.³¹ In a case of exuberant MC lesions after beginning HAART, the lesions spontaneously resolved with the progression of immune reconstitution.²⁸

Malignancies
Patients with hematologic malignancies such as lymphoma and leukemia comprise another subset of patients at risk for atypical presentations of MC. Molluscum contagiosum has been described in patients with hematologic malignancies such as adult T-cell leukemia/lymphoma, multiple myeloma, chronic myeloid leukemia, acute lymphoblastic leukemia, lymphomatoid papulosis, and non-Hodgkin lymphoma. In a review of MC in children with cancer, 0.5% were diagnosed with MC.^32,33 Reports also have documented eruptive MC in the presence of solid organ cancers, including lung cancer.³⁴

In patients with malignancies, the differential diagnosis should include other common dermatologic conditions such as varicella, herpes simplex, papillomas, pyoderma, and cutaneous cryptococcosis, as well as MC. Similar to HIV-positive patients, the lesions of MC described in patients with malignancies do not tend to spontaneously resolve. In a report of a pediatric patient with acute lymphoblastic leukemia, MC presented as an ulcerated lesion without any classic features, requiring biopsy for definitive diagnosis. Only partial resolution was achieved with cryotherapy and crusting of the lesion in an attempt to slow the progression.³⁵ In a series of 5 children with hematologic malignancies and MC, little improvement was noted after treatment with surgical scraping, liquid nitrogen, and salicylic acid ointment 5%. Similar to patients with HIV, improvement of immune status and function help clear the disease, and patients who reach remission and discontinue chemotherapeutic agents have a higher rate of spontaneous resolution of previously recalcitrant MC lesions.³⁶

Transplant Patients
Molluscum contagiosum in transplant patients has features similar to patients with HIV/AIDS. In organ transplant recipients, there is an increased risk for cutaneous disease from iatrogenic immunosuppression or immunosuppression through infectious or neoplastic processes.³⁷ As in other immunocompromised populations, MC often has an atypical presentation in transplant patients with more extensive involvement and recalcitrant, rapidly recurring lesions.

In a review of 145 pediatric organ transplant recipients, MC was the fourth most common skin infection after verruca vulgaris, tinea versicolor, and herpes simplex/zoster. Affecting 7% of patients, the majority of patients demonstrated clinically typical lesions; however, the disease was difficult to eradicate if multiple lesions were present.³⁷ In other reports in adults, fulminant and giant MC have been described after renal and other solid organ transplants.^38,39 Molluscum contagiosum also has been reported to mimic other skin diseases in transplant patients including tinea barbae⁴⁰ and nodular basal cell carcinomas.⁴¹

The standard treatments are identical to those used in patients with HIV, including ablative methods via liquid nitrogen, electrocautery, cantharidin, trichloroacetic acid, and topical retinoids. Similar to MC in other immunocompromised states, treatment can be difficult and usually requires multiple modalities. For children, imiquimod cream 5% has been recommended due to high clearance rates (up to 92%) and the painless nature of the treatment.^42,43

Other Iatrogenic Immunosuppressive States
Immunosuppression through the use of steroids, chemotherapeutic agents, and biologic drugs often is the result of treatment of various diseases. In patients with psoriasis treated with systemic immunosuppressive agents, there are numerous reports that describe the appearance of eruptive MC in association with methotrexate, cyclosporine, and biologics. Methotrexate acts as an immunosuppressive agent by binding to dihydrofolate reductase, which inhibits DNA synthesis in immunologically competent cells.⁴⁴ It also may block host defense mechanisms against MC by suppressing the expression of serum inflammatory cytokines such as tumor necrosis factor α (TNF-α) and IFN-γ and suppressing the activity of TNF-α inducing apoptosis of virus-infected cells. Cyclosporine used in conjunction with methotrexate may exacerbate the insult to the immune system by inhibiting the production of IFN-γ.⁴⁵ Biologics are an emerging class of drugs that have demonstrated efficacy in moderate to severe psoriasis by inhibiting TNF-α or other inflammatory molecules. Several published reports have described eruptive or atypical MC in patients on biologic medications. In one case, within 2 weeks after initiation of infliximab, a monoclonal antibody against TNF-α, a patient developed an eruption of MC involving the entire body.⁴⁶ In another report, an anti–TNF-α agent for rheumatoid arthritis was associated with atypical MC with eyelid lesions.⁴⁷

There are other skin disorders treated with immunosuppressive agents that also have been associated with MC. In a patient with pemphigus vulgaris treated with prednisolone, pimecrolimus, and azathioprine, MC lesions were observed on the face and within healed pemphigus vulgaris sites.⁴⁸ Pimecrolimus and tacrolimus, corticosteroid-sparing agents, suppress cell-mediated immunity and inhibit inflammatory cytokines such as IL-2. The infection resolved with a gradual tapering of immunosuppressive therapy and 10 sessions of cryotherapy.⁴⁸ In a case of topical pimecrolimus for pityriasis alba, the patient developed biopsy-proven MC within 2 weeks of initiating treatment in the areas that were treated with tacrolimus.⁴⁹

In nontransplant patients with iatrogenic immunosuppression, MC treatment has not been documented to be as challenging as in patients with inherent immunosuppression. Most patients respond to either withdrawal of the drug alone or to simple ablative treatments such as cryotherapy.^45,46,48 This important difference is most likely due to the presence of an otherwise intact immune system.

Conclusion

This case describes the appearance of MC in a patient with psoriasis treated with a TNF-α inhibitor who was ultimately diagnosed with AIDS. Although atypical MC infections have been documented in patients with psoriasis undergoing treatment with biologics, it is thought to be more common for MC to occur in more remarkably immunocompromised states such as AIDS. Thus, the persistence and progression of MC in our patient despite discontinuation of etanercept suggested a separate underlying process. Subsequent workup led to the diagnosis of AIDS along with the opportunistic ocular infection of toxoplasmosis retinitis. This clinical sequence consisting of psoriasis treated with a biologic agent, development of MC, and subsequent diagnosis of AIDS is unique and clinically significant to dermatologists. The presentation of psoriasis in patients with HIV can be diverse with different levels of severity and atypical clinical features. In many cases, HIV is known to exacerbate the classic clinical presentation of psoriasis. However, there are other particular presentations of psoriasis in HIV patients that have been observed, which include a predilection for scalp lesions, palmoplantar keratoderma, flexural involvement, and higher levels of immunodeficiency.⁵⁰ Although tuberculin skin tests are required prior to initiating biologic therapy due to the potential for disease reactivation, there are no requirements for HIV antibody testing. In cases of severe recalcitrant psoriasis, an HIV test should be ordered during the workup to establish an early diagnosis so that an HIV-positive patient can avoid poor outcomes from either the disease processes, the use of certain therapeutic agents, or both. Furthermore, the benefit of avoiding possible harm to the patient and potential legal action outweighs the cost of performing surveillance HIV testing in this subset of patients. Thus, due to the potential additive immunosuppressive effect of HIV with biologic therapy, providers should always assess for risk factors and consider testing for HIV in all patients before initiating treatment with immunosuppressive agents such as biologics.

Molluscum contagiosum (MC) is a double-stranded DNA virus of the Poxviridae family, which commonly infects human keratinocytes resulting in small, umbilicated, flesh-colored papules. The greatest incidence of MC is seen in the pediatric population and sexually active young adults, and it is considered a self-limited disease in immunocompetent individuals.¹ With the emergence of the human immunodeficiency virus (HIV) and subsequent AIDS epidemic in the 1980s, a new population of immunocompromised individuals has been observed to be increasingly susceptible to MC with an atypical clinical presentation and a recalcitrant disease course.² Although the increased prevalence of MC in the HIV population has been well-documented, it has been observed in other disease states or iatrogenically induced immunosuppression due to a deficiency in function or absolute number of T lymphocytes.

We present a case of a patient with long-standing psoriasis on biologic therapy who presented with MC with a subsequent workup that revealed AIDS. This case reiterates the importance of MC as a potential indicator of underlying immunosuppression. We review the literature to evaluate the occurrence of MC in immunosuppressed patients.

In these patients, the lesions often are too voluminous for conservative therapy and require excision.⁶ Atypical MC lesions also can resemble other dermatologic conditions, including condyloma acuminatum,⁷ nevus sebaceous of Jadassohn, ecthyma,⁸ and cutaneous horns,^9,10 as well as other bacterial and fungal infections in HIV-positive patients, such as cutaneous Cryptococcus neoformans,^11,12 disseminated histoplasmosis,¹³ and infections caused by Penicillium marneffei¹⁴ and Bartonella henselae.¹⁵ In most cases of MC in HIV-positive patients, diagnosis is dependent on the examination of biopsy specimens, which maintain the same histopathologic features regardless of immune status.

The management of MC in patients with HIV/AIDS is difficult. Molluscum contagiosum has shown no evidence of spontaneous resolution in patients with HIV, and treatment with one modality is often insufficient. Treatment is most successful when a combination approach is utilized with destructive procedures (eg, curettage, cryosurgery) and adjunctive agents (eg, retinoids, cantharidin, trichloroacetic acid). Imiquimod and cidofovir have been used off label for MC in AIDS patients.¹⁶ Imiquimod, which is used to treat genital warts, another cutaneous viral infection seen in patients with HIV, has demonstrated efficacy in treating MC.¹⁶ In a randomized controlled trial comparing imiquimod cream 5% to cryotherapy for MC in healthy children, imiquimod was slow acting but better suited than cryotherapy for patients with eruptions of many small lesions.¹⁷ For HIV patients, numerous reports have described successful treatment of disseminated or recalcitrant MC with topical imiquimod.^18-20 Cidofovir, an antiviral used to treat cytomegalovirus retinitis in patients with AIDS, is a promising antiviral agent against the poxvirus family. In a study of viral DNA polymerase genes of MC virus, cidofovir inhibited MC virus DNA polymerase activity.²¹ It has been used in both topical (1% to 3%) and intravenous form to successfully treat recalcitrant and exuberant giant MC.^6,22 However, the use of cidofovir is limited by its high costs, especially when compounded into a topical formulation.²³

From a systemic standpoint, numerous reports have shown that treating the underlying HIV by optimizing HAART is the most important first step in clearing MC.^24-27 However, a special concern regarding the initiation of HAART in patients with MC as well as a markedly impaired immune function is the development of an inflammatory reaction called immune reconstitution inflammatory syndrome (IRIS). This reaction is thought to be a result of immune recovery in severely immunosuppressed patients. During the initial phase of reconstitution when CD4 lymphocyte counts rise and viral load decreases, IRIS occurs due to an inflammatory reaction to microbial and autoimmune antigens, leading to temporary clinical deterioration.²⁸ The incidence has been reported in up to 25% of patients starting HAART, and 52% to 78% of IRIS cases involve dermatologic manifestations such as varicella-zoster virus, cytomegalovirus infections, genital warts, and MC.^29,30 In a cohort study of 199 patients, 2% of patients developed MC within 6 months of initiating HAART.³¹ In a case of exuberant MC lesions after beginning HAART, the lesions spontaneously resolved with the progression of immune reconstitution.²⁸

Malignancies
Patients with hematologic malignancies such as lymphoma and leukemia comprise another subset of patients at risk for atypical presentations of MC. Molluscum contagiosum has been described in patients with hematologic malignancies such as adult T-cell leukemia/lymphoma, multiple myeloma, chronic myeloid leukemia, acute lymphoblastic leukemia, lymphomatoid papulosis, and non-Hodgkin lymphoma. In a review of MC in children with cancer, 0.5% were diagnosed with MC.^32,33 Reports also have documented eruptive MC in the presence of solid organ cancers, including lung cancer.³⁴

In patients with malignancies, the differential diagnosis should include other common dermatologic conditions such as varicella, herpes simplex, papillomas, pyoderma, and cutaneous cryptococcosis, as well as MC. Similar to HIV-positive patients, the lesions of MC described in patients with malignancies do not tend to spontaneously resolve. In a report of a pediatric patient with acute lymphoblastic leukemia, MC presented as an ulcerated lesion without any classic features, requiring biopsy for definitive diagnosis. Only partial resolution was achieved with cryotherapy and crusting of the lesion in an attempt to slow the progression.³⁵ In a series of 5 children with hematologic malignancies and MC, little improvement was noted after treatment with surgical scraping, liquid nitrogen, and salicylic acid ointment 5%. Similar to patients with HIV, improvement of immune status and function help clear the disease, and patients who reach remission and discontinue chemotherapeutic agents have a higher rate of spontaneous resolution of previously recalcitrant MC lesions.³⁶

Transplant Patients
Molluscum contagiosum in transplant patients has features similar to patients with HIV/AIDS. In organ transplant recipients, there is an increased risk for cutaneous disease from iatrogenic immunosuppression or immunosuppression through infectious or neoplastic processes.³⁷ As in other immunocompromised populations, MC often has an atypical presentation in transplant patients with more extensive involvement and recalcitrant, rapidly recurring lesions.

In a review of 145 pediatric organ transplant recipients, MC was the fourth most common skin infection after verruca vulgaris, tinea versicolor, and herpes simplex/zoster. Affecting 7% of patients, the majority of patients demonstrated clinically typical lesions; however, the disease was difficult to eradicate if multiple lesions were present.³⁷ In other reports in adults, fulminant and giant MC have been described after renal and other solid organ transplants.^38,39 Molluscum contagiosum also has been reported to mimic other skin diseases in transplant patients including tinea barbae⁴⁰ and nodular basal cell carcinomas.⁴¹

The standard treatments are identical to those used in patients with HIV, including ablative methods via liquid nitrogen, electrocautery, cantharidin, trichloroacetic acid, and topical retinoids. Similar to MC in other immunocompromised states, treatment can be difficult and usually requires multiple modalities. For children, imiquimod cream 5% has been recommended due to high clearance rates (up to 92%) and the painless nature of the treatment.^42,43

Other Iatrogenic Immunosuppressive States
Immunosuppression through the use of steroids, chemotherapeutic agents, and biologic drugs often is the result of treatment of various diseases. In patients with psoriasis treated with systemic immunosuppressive agents, there are numerous reports that describe the appearance of eruptive MC in association with methotrexate, cyclosporine, and biologics. Methotrexate acts as an immunosuppressive agent by binding to dihydrofolate reductase, which inhibits DNA synthesis in immunologically competent cells.⁴⁴ It also may block host defense mechanisms against MC by suppressing the expression of serum inflammatory cytokines such as tumor necrosis factor α (TNF-α) and IFN-γ and suppressing the activity of TNF-α inducing apoptosis of virus-infected cells. Cyclosporine used in conjunction with methotrexate may exacerbate the insult to the immune system by inhibiting the production of IFN-γ.⁴⁵ Biologics are an emerging class of drugs that have demonstrated efficacy in moderate to severe psoriasis by inhibiting TNF-α or other inflammatory molecules. Several published reports have described eruptive or atypical MC in patients on biologic medications. In one case, within 2 weeks after initiation of infliximab, a monoclonal antibody against TNF-α, a patient developed an eruption of MC involving the entire body.⁴⁶ In another report, an anti–TNF-α agent for rheumatoid arthritis was associated with atypical MC with eyelid lesions.⁴⁷

There are other skin disorders treated with immunosuppressive agents that also have been associated with MC. In a patient with pemphigus vulgaris treated with prednisolone, pimecrolimus, and azathioprine, MC lesions were observed on the face and within healed pemphigus vulgaris sites.⁴⁸ Pimecrolimus and tacrolimus, corticosteroid-sparing agents, suppress cell-mediated immunity and inhibit inflammatory cytokines such as IL-2. The infection resolved with a gradual tapering of immunosuppressive therapy and 10 sessions of cryotherapy.⁴⁸ In a case of topical pimecrolimus for pityriasis alba, the patient developed biopsy-proven MC within 2 weeks of initiating treatment in the areas that were treated with tacrolimus.⁴⁹

In nontransplant patients with iatrogenic immunosuppression, MC treatment has not been documented to be as challenging as in patients with inherent immunosuppression. Most patients respond to either withdrawal of the drug alone or to simple ablative treatments such as cryotherapy.^45,46,48 This important difference is most likely due to the presence of an otherwise intact immune system.

Conclusion

This case describes the appearance of MC in a patient with psoriasis treated with a TNF-α inhibitor who was ultimately diagnosed with AIDS. Although atypical MC infections have been documented in patients with psoriasis undergoing treatment with biologics, it is thought to be more common for MC to occur in more remarkably immunocompromised states such as AIDS. Thus, the persistence and progression of MC in our patient despite discontinuation of etanercept suggested a separate underlying process. Subsequent workup led to the diagnosis of AIDS along with the opportunistic ocular infection of toxoplasmosis retinitis. This clinical sequence consisting of psoriasis treated with a biologic agent, development of MC, and subsequent diagnosis of AIDS is unique and clinically significant to dermatologists. The presentation of psoriasis in patients with HIV can be diverse with different levels of severity and atypical clinical features. In many cases, HIV is known to exacerbate the classic clinical presentation of psoriasis. However, there are other particular presentations of psoriasis in HIV patients that have been observed, which include a predilection for scalp lesions, palmoplantar keratoderma, flexural involvement, and higher levels of immunodeficiency.⁵⁰ Although tuberculin skin tests are required prior to initiating biologic therapy due to the potential for disease reactivation, there are no requirements for HIV antibody testing. In cases of severe recalcitrant psoriasis, an HIV test should be ordered during the workup to establish an early diagnosis so that an HIV-positive patient can avoid poor outcomes from either the disease processes, the use of certain therapeutic agents, or both. Furthermore, the benefit of avoiding possible harm to the patient and potential legal action outweighs the cost of performing surveillance HIV testing in this subset of patients. Thus, due to the potential additive immunosuppressive effect of HIV with biologic therapy, providers should always assess for risk factors and consider testing for HIV in all patients before initiating treatment with immunosuppressive agents such as biologics.

Molluscum contagiosum (MC) is a double-stranded DNA virus of the Poxviridae family, which commonly infects human keratinocytes resulting in small, umbilicated, flesh-colored papules. The greatest incidence of MC is seen in the pediatric population and sexually active young adults, and it is considered a self-limited disease in immunocompetent individuals.¹ With the emergence of the human immunodeficiency virus (HIV) and subsequent AIDS epidemic in the 1980s, a new population of immunocompromised individuals has been observed to be increasingly susceptible to MC with an atypical clinical presentation and a recalcitrant disease course.² Although the increased prevalence of MC in the HIV population has been well-documented, it has been observed in other disease states or iatrogenically induced immunosuppression due to a deficiency in function or absolute number of T lymphocytes.

We present a case of a patient with long-standing psoriasis on biologic therapy who presented with MC with a subsequent workup that revealed AIDS. This case reiterates the importance of MC as a potential indicator of underlying immunosuppression. We review the literature to evaluate the occurrence of MC in immunosuppressed patients.

Case Report

A 33-year-old man initially presented for evaluation of severe plaque-type psoriasis associated with pain, erythema, and swelling of the joints of the hands of 10 years’ duration. He was started on methotrexate 5 mg weekly and topical corticosteroids but was unable to tolerate methotrexate due to headaches. He also had difficulty affording topical medications and adjunctive phototherapy. The patient was sporadically seen in follow-up with persistence of psoriatic plaques involving up to 60% body surface area (BSA) with the only treatment consisting of occasional topical steroids. Five years later, the patient was restarted on methotrexate 5 to 7.5 mg weekly, which resulted in moderate improvement. However, because of persistent elevation of liver enzymes, this treatment was stopped. Several months later he was evaluated for treatment with a biologic agent, and after a negative tuberculin skin test, he began treatment with etanercept 50 mg subcutaneous injection twice weekly, which provided notable improvement and allowed for reduction of dose frequency to once weekly.

At follow-up 1 year later, the patient had continued improvement of psoriasis with approximately 30% BSA on a treatment regimen of etanercept 50 mg weekly injection and topical corticosteroids. However, on physical examination, there were multiple small semitranslucent papules with telangiectases on the chest and upper back (Figure 1). Biopsy of a representative papule on the chest revealed MC (Figure 2). The patient was subsequently advised to stop etanercept and to return immediately to the clinic for HIV testing. He returned for follow-up 3 months later with pronounced worsening of disease and a new onset of blurred vision of the right eye. Cutaneous examination revealed numerous large erythematous plaques with superficial scale and cerebriform surface on the chest, back, abdomen, and upper and lower extremities involving 80% BSA (Figure 3). Biopsy of a plaque demonstrated psoriasiform dermatitis with neutrophils and parakeratosis consistent with psoriasis. Extensive blood work was notable for reactive HIV antibody and lymphopenia, CD4 lymphocyte count of 60 cells/mm³, and an HIV viral load of 247,000 copies/mL, meeting diagnostic criteria for AIDS. Additionally, ophthalmologic evaluation revealed toxoplasma retinitis. Upon initiation of highly active antiretroviral therapy (HAART) and continued use of topical corticosteroids, the patient experienced notable improvement of disease severity with approximately 20% BSA.

Comment

Molluscum contagiosum is a common skin infection. Among patients with HIV and other types of impaired cellular immunity, the prevalence of MC is estimated to be as high as 20%.³ The MC poxvirus survives and proliferates within the epidermis by interfering with tumor necrosis factor–induced apoptosis of virally infected cells; therefore, intact cell-mediated immunity is an important component of prevention and clearance of poxvirus infections. In immunocompromised patients, the presentation of MC varies widely, and the disease is often difficult to eradicate. This review will highlight the prevalence, presentation, and treatment of MC in the context of immunosuppressed states.

HIV/AIDS
Molluscum contagiosum in HIV-positive patients was first recognized in 1983,² and its prevalence is estimated to range from 5% to 18% in AIDS patients.³ Molluscum contagiosum is a clinical sign of HIV progression, and its incidence appears to increase with reduced immune function (ie, a CD4 cell count <200/mm³).³ In a study of 456 patients with HIV-associated skin disorders, the majority of patients with MC had notable immunosuppression with a median survival time of 12 months. Thus, MC was not an independent prognostic marker but a clinical indicator of markedly reduced immune status.⁴

Molluscum contagiosum is transmitted in both sexual and nonsexual patterns in HIV-positive individuals, with the distribution of the latter involving primarily the face and neck. Although it may present with typical umbilicated papules, MC has a wide range of atypical clinical presentations in patients with AIDS that can make it difficult to diagnose. Complicated cases of eyelid MC have been reported in advanced HIV in both adults and children, resulting in obstruction of vision due to large lesions (up to 2 cm) or hundreds of confluent lesions.⁵ Giant MC, which appears as large exophytic nodules, is another presentation that has been frequently described in patients with advanced HIV.

Nail-patella syndrome (NPS), also known as hereditary osteo-onychodysplasia syndrome, is a rare autosomal-dominant disorder with an estimated incidence of 1 per 50,000 individuals in the United States. Nail-patella syndrome presents due to a heterozygous loss-of-function mutation in the LIM homeobox transcription factor 1 beta gene, LMX1B, on chromosome 9q34.¹ LMX1B gene mutations are fully penetrant, but there is variable expressivity, even within families.²

Case Report

A 69-year-old man presented to the dermatology clinic for a routine skin cancer screening. The patient’s history was remarkable for dystrophic fingernails and toenails since birth. In his 20s he developed progressively worsening instability of the left knee and chronic back pain due to scoliosis, lumbar lordosis, and spinal disc herniation. Since then, he underwent knee surgery and 7 back surgeries for rheumatologic disease. His medical history also was remarkable for osteoporosis, hypertension, and glaucoma. Family history was notable for similar findings in the patient’s sister; mother; and maternal aunt, uncle, and grandmother, all with varying disease severity.

Physical examination was remarkable for bilateral fingernail hypoplasia that was most prominent on the thumb, with improvement in each nail on progression toward the fifth digit (Figure 1A). Triangular fingernail lunulae, longitudinal ridging, and nail splitting were present (Figure 1A and 1B). Hypoplastic crumbly toenails also were appreciated (Figure 1C). Skin creases over the distal interphalangeal joints of the fingers and toes were conspicuously absent. Limited range of motion was noted in multiple joints, with profound limitation of bilateral elbow extension. Review of prior imaging reports revealed bilateral iliac horns as well as left patellar absence and right patellar hypoplasia (Figure 2). Urinalysis was remarkable for proteinuria and microscopic hematuria. Given the constellation of examination findings and positive family history, a diagnosis of NPS was made.

Comment

Nail-patella syndrome is characterized by variable dermatologic, neurologic, nephrogenic, ophthalmologic, and orthopedic clinical manifestations.³ Almost all patients with NPS have bilateral and symmetric nail changes, including absent or hypoplastic nails with ridging, splitting, or discoloration and triangular-shaped lunulae.^1,4 Nail findings are the most consistent findings of NPS, as they are present in more than 98% of patients.⁵ The thumb often is the most severely affected nail, with improvement appreciated on progression toward the fifth digit, as seen in our patient (Figure 1A).⁵ Each individual nail usually is more severely affected on its ulnar side. When toenails are involved, the abnormalities tend to be less severe, and the little toenail is most commonly affected. Distal digital changes also are observed in almost all patients. Loss of dorsal creases in the skin overlying the distal interphalangeal joints can be considered as a diagnostic clue.^3,4

There are a variety of orthopedic manifestations of NPS. Hypoplastic or absent patellae leading to recurrent subluxations or dislocations is a common finding.⁴ Bilateral symmetric bone formations (horns) arising from the iliac crest are pathognomonic but only found on radiography 70% of the time.⁶ Occasionally these protuberances can be palpated on physical examination,⁵ though this finding was not appreciated in our patient. Dysplasia of the elbows may result in limited elbow extension and limited pronation and supination. Early degenerative arthritis, lumbar lordosis, and scoliosis also are not uncommon. In addition, skeletal integrity is compromised, leading to early osteoporosis and increased risk for fractures.⁵

Nephropathy develops in approximately 30% to 40% of patients and is a major determinant of mortality in these patients.² Mutations in the LMX1B gene lead to abnormal development of podocytes and reduction in collagen in the glomerular basement membrane. The first sign of renal involvement usually is proteinuria, with or without microscopic hematuria. As in our patient, many patients develop hypertension. Patients may progress to develop nephrotic syndrome and end-stage renal failure (5%–10%).⁷ Death from NPS-related nephropathy has occurred, even in childhood.^4,5

Primary open-angle glaucoma has been recognized as a feature of NPS.⁸ It is the most frequent ocular abnormality observed, followed by ocular hypertension and Lester sign of the iris.^3,5 These conditions also are more common in younger patients with NPS than in the general population.⁵ Important neurologic findings include epilepsy, peripheral neuropathy, attention deficit disorder, major depressive disorder, and vasomotor problems.⁹

Our case highlights the importance of recognizing this rare condition to provide a multidisciplinary approach to care that addresses all aspects of LMX1B-associated disease in affected individuals. Nail findings may be the first clue to the need for additional screenings in these patients. Nail-patella syndrome patients should undergo thorough ophthalmologic examinations every 2 years, including measurement of intraocular pressure, examination of the optic disc, and assessment of visual fields. Given the variability in severity of joint problems and the unpredictable anatomy of the joints, magnetic resonance imaging of the joints is recommended prior to orthopedic intervention. Most importantly, physicians should recognize this genodermatosis to implement periodic screenings for renal disease, as up to 40% of NPS patients develop kidney failure. Annual blood pressure measurements, urinalysis, and measurement of the protein to creatinine ratio in the urine are recommended. For patients with end-stage renal failure, renal transplantation results in cure of nephropathy and may even result in nail regrowth.¹⁰ Further, this case is notable in that it describes a patient with NPS who is older than most other individuals presenting with the condition, thereby revealing novel information about NPS in its more advanced stages.

The first sign of renal involvement usually is proteinuria, with or without microscopic hematuria. As in our patient, many patients develop hypertension. Patients may progress to develop nephrotic syndrome and end-stage renal failure (5%–10%).⁷ Death from NPS-related nephropathy has occurred, even in childhood.^4,5

Primary open-angle glaucoma has been recognized as a feature of NPS.⁸ It is the most frequent ocular abnormality observed, followed by ocular hypertension and Lester sign of the iris.^3,5 These conditions also are more common in younger patients with NPS than in the general population.⁵ Important neurologic findings include epilepsy, peripheral neuropathy, attention deficit disorder, major depressive disorder, and vasomotor problems.⁹

Our case highlights the importance of recognizing this rare condition to provide a multidisciplinary approach to care that addresses all aspects of LMX1B-associated disease in affected individuals. Nail findings may be the first clue to the need for additional screenings in these patients. Nail-patella syndrome patients should undergo thorough ophthalmologic examinations every 2 years, including measurement of intraocular pressure, examination of the optic disc, and assessment of visual fields. Given the variability in severity of joint problems and the unpredictable anatomy of the joints, magnetic resonance imaging of the joints is recommended prior to orthopedic intervention. Most importantly, physicians should recognize this genodermatosis to implement periodic screenings for renal disease, as up to 40% of NPS patients develop kidney failure. Annual blood pressure measurements, urinalysis, and measurement of the protein to creatinine ratio in the urine are recommended. For patients with end-stage renal failure, renal transplantation results in cure of nephropathy and may even result in nail regrowth.¹⁰ Further, this case is notable in that it describes a patient with NPS who is older than most other individuals presenting with the condition, thereby revealing novel information about NPS in its more advanced stages.

Nail-patella syndrome (NPS), also known as hereditary osteo-onychodysplasia syndrome, is a rare autosomal-dominant disorder with an estimated incidence of 1 per 50,000 individuals in the United States. Nail-patella syndrome presents due to a heterozygous loss-of-function mutation in the LIM homeobox transcription factor 1 beta gene, LMX1B, on chromosome 9q34.¹ LMX1B gene mutations are fully penetrant, but there is variable expressivity, even within families.²

Case Report

A 69-year-old man presented to the dermatology clinic for a routine skin cancer screening. The patient’s history was remarkable for dystrophic fingernails and toenails since birth. In his 20s he developed progressively worsening instability of the left knee and chronic back pain due to scoliosis, lumbar lordosis, and spinal disc herniation. Since then, he underwent knee surgery and 7 back surgeries for rheumatologic disease. His medical history also was remarkable for osteoporosis, hypertension, and glaucoma. Family history was notable for similar findings in the patient’s sister; mother; and maternal aunt, uncle, and grandmother, all with varying disease severity.

Physical examination was remarkable for bilateral fingernail hypoplasia that was most prominent on the thumb, with improvement in each nail on progression toward the fifth digit (Figure 1A). Triangular fingernail lunulae, longitudinal ridging, and nail splitting were present (Figure 1A and 1B). Hypoplastic crumbly toenails also were appreciated (Figure 1C). Skin creases over the distal interphalangeal joints of the fingers and toes were conspicuously absent. Limited range of motion was noted in multiple joints, with profound limitation of bilateral elbow extension. Review of prior imaging reports revealed bilateral iliac horns as well as left patellar absence and right patellar hypoplasia (Figure 2). Urinalysis was remarkable for proteinuria and microscopic hematuria. Given the constellation of examination findings and positive family history, a diagnosis of NPS was made.

Comment

Nail-patella syndrome is characterized by variable dermatologic, neurologic, nephrogenic, ophthalmologic, and orthopedic clinical manifestations.³ Almost all patients with NPS have bilateral and symmetric nail changes, including absent or hypoplastic nails with ridging, splitting, or discoloration and triangular-shaped lunulae.^1,4 Nail findings are the most consistent findings of NPS, as they are present in more than 98% of patients.⁵ The thumb often is the most severely affected nail, with improvement appreciated on progression toward the fifth digit, as seen in our patient (Figure 1A).⁵ Each individual nail usually is more severely affected on its ulnar side. When toenails are involved, the abnormalities tend to be less severe, and the little toenail is most commonly affected. Distal digital changes also are observed in almost all patients. Loss of dorsal creases in the skin overlying the distal interphalangeal joints can be considered as a diagnostic clue.^3,4

There are a variety of orthopedic manifestations of NPS. Hypoplastic or absent patellae leading to recurrent subluxations or dislocations is a common finding.⁴ Bilateral symmetric bone formations (horns) arising from the iliac crest are pathognomonic but only found on radiography 70% of the time.⁶ Occasionally these protuberances can be palpated on physical examination,⁵ though this finding was not appreciated in our patient. Dysplasia of the elbows may result in limited elbow extension and limited pronation and supination. Early degenerative arthritis, lumbar lordosis, and scoliosis also are not uncommon. In addition, skeletal integrity is compromised, leading to early osteoporosis and increased risk for fractures.⁵

Melkersson-Rosenthal syndrome (MRS) is a rare condition comprised of unilateral peripheral facial nerve palsy, episodic or progressive facial edema, and lingua plicata (also known as fissured tongue). Melkersson-Rosenthal syndrome is a subtype of orofacial granulomatosis and often is mistaken for angioedema or pseudoangioedema due to the swelling of the lips and eyelids. We present a case of MRS that cleared in response to adalimumab therapy.

Case Report

A 69-year-old woman presented to our dermatology clinic with facial edema and a fissured tongue of 4 years’ duration. These symptoms had failed to improve with doxycycline, tacrolimus ointment 0.1%, and cortisone injections of the upper lip, as well as a balsam-free diet, fragrance-free skin products, and flavor-free toothpaste prescribed by multiple physicians over 4 years. Two weeks prior to the current presentation the patient developed left facial nerve palsy that was diagnosed by an outside physician as Bell palsy, and the patient completed a 7-day course of prednisone 1 day prior to presentation. The patient’s medical history was remarkable for type 2 diabetes mellitus controlled with metformin, hyperlipidemia controlled with ezetimibe-simvastatin, and psoriasis. She reported no family history of autoimmune or dermatologic disorders and denied any fever, unintentional weight loss, nausea, vomiting, or diarrhea.

On physical examination, the patient had considerable perioral edema and erythema without warmth or tenderness (Figure 1A). The tongue was fissured with notable scalloping at the lateral margins (Figure 1B). There were no aphthous ulcers or lymphadenopathy, and the remainder of the neurologic examination was normal. The patient had erythematous plaques with scaling on the bilateral elbows. Cardiopulmonary, musculoskeletal, and abdominal examinations were otherwise normal.

Laboratory data revealed an elevated white blood cell count of 17,500/µL (reference range, 4500–11,000/µL), an elevated absolute neutrophil count of 14,018/µL (reference range, 0–700/µL), and an absolute eosinophil count of 0/µL (reference range, 0–450/µL), with the rest of the complete blood cell count within reference range. A basic metabolic panel showed an elevated glucose level of 326 mg/dL (reference range, 70–110 mg/dL), consistent with diabetes and most likely exacerbated by the recent steroid course. A lipid panel was consistent with diagnosed hyperlipidemia (total cholesterol, 236 mg/dL [reference range, <200 mg/dL]; low-density lipoprotein, 134 mg/dL [reference range, 10–30 mg/dL]; triglycerides, 188 mg/dL [reference range, <160 mg/dL]). Hepatitis B and C tests were negative. A punch biopsy of the buccal and labial mucosa was taken, revealing a parakeratinized stratified squamous epithelium with an unusual pattern of surface keratinization with foci of intracellular and extracellular edema in the spinous layer. The underlying fibrous connective tissue was edematous with infiltrates of lymphocytes, mast cells, macrophages, and a few plasma cells. The pathology report listed the diagnosis as nonspecific “chronic mucositis,” with a list of differential diagnoses that included angioedema, hypersensitivity reaction, or other possible autoimmune disorders.

On consideration of these differential diagnoses, it was felt most likely to be MRS, which remains a primarily clinical diagnosis characterized by the triad of symptoms seen in this patient. Treatment of this condition emphasizes inflammation, and steroid therapy often is utilized, as it was in our patient. After the diagnosis of MRS was made, the patient received adalimumab 80 mg subcutaneously on day 1 and 40 mg on day 8 as a loading dose; she subsequently began a course of subcutaneous injections of adalimumab 40 mg once every other week for treatment of psoriasis with the goal of simultaneously treating the MRS. The symptoms did not completely resolve at this dose, so it was increased to 40 mg once weekly. The patient reported that the facial edema, lingua plicata, and facial nerve palsy resolved concomitantly over approximately 3 months with greater improvement at 5 months (Figure 2). The patient has had no relapses as of the last follow-up at 11 months.

Comment

Melkersson-Rosenthal syndrome usually presents sporadically, though there are reports of familial association,^1-3 and only 8% to 25% of patients worldwide present with the complete triad of symptoms.⁴ The pathogenesis of the syndrome is controversial. Granulomatous changes have been found in patients experiencing chronic edema. However, according to Zimmer et al⁵ in a study of 42 MRS patients, only 46% (19/42) had granulomatous changes; 36% (15/42) had nonspecific inflammation, 11% (5/42) had incidental findings, and 7% (3/42) showed no histopathologic abnormalities. Granulomatous cheilitis is a subtype of orofacial granulomatosis, an idiopathic process that causes swelling of the face and lips as well as intraoral swelling and ulceration. Orofacial granulomatosis is referred to as granulomatous cheilitis when the lip is involved. Melkersson-Rosenthal syndrome is another subtype of orofacial granulomatosis that includes facial palsy and fissured tongue.^6,7

In a clinical study of 7 patients with MRS, Liu and Yu¹ found 3 (42%) patients to have dysarthria, dysphagia, and tongue muscle atrophy; 1 patient to have migrainelike headaches; 1 patient to have decreased vision and an ocular movement disorder; 1 patient to have ipsilateral hearing loss; and 1 patient to lack any other symptoms. Halevy et al⁸ suggested a possible association of MRS with psoriasis. In their review of 12 patients, 1 (8%) had psoriatic arthritis, 2 (17%) had skin biopsy–proven psoriasis, and 3 (25%) had a family history of psoriasis.⁸ Because the disease is quite rare, it is difficult to determine other symptoms that may be associated with the disease.

Tumor necrosis factor α (TNF-α) is needed for granuloma formation, and TNF-α antagonists have been used to treat a number of granulomatous conditions including Crohn disease and sarcoidosis.^9-11 Two case reports indicate that infliximab, a mouse/human chimeric monoclonal antibody to TNF-α, has been used successfully to clear MRS.^12,13 One report cited the use of adalimumab for maintenance therapy of MRS,¹² and more recently, adalimumab has been reported for refractory MRS.¹⁴ However, there currently are no known reports regarding the efficacy of adalimumab as a first-line treatment of MRS.

Adalimumab is a fully human monoclonal antibody to TNF-α, which is administered via subcutaneous injections. Infliximab must be administered at an infusion center, making treatment logistically more difficult for patients, and can be associated with the development of infusion reactions, though the exact data on infusion reactions are difficult to estimate due to variations in reporting.^15,16

In 2014, Stein et al¹⁴ reported a case of refractory MRS in a 29-year-old man associated with acute attacks of hearing loss. The patient’s symptoms were controlled with high-dose prednisolone but were unable to be maintained on methotrexate or azathioprine as steroid-sparing agents. The patient was loaded with adalimumab 80 mg subcutaneously once on day 1 and was continued on 40 mg subcutaneously once every 3 weeks, gradually extending to once every 4 weeks when symptoms improved. The patient was slowly weaned off prednisolone 16 months after starting adalimumab. After 20 months, adalimumab therapy was discontinued and the patient remained recurrence free at 4 years’ follow-up.¹⁴ In another case, adalimumab was utilized as maintenance therapy after initial improvement with infliximab.¹² Kakimoto et al¹² reported a previously healthy 19-year-old woman with edema of the bilateral eyelids and upper lip. The authors determined the patient had MRS despite the lack of fissured tongue or facial nerve palsy and started infliximab. The condition resolved after the patient’s second infusion of infliximab and completely cleared after the third infusion; however, she had logistical difficulties reaching the infusion center and disliked the flulike response she experienced with the treatment. She was started on once weekly subcutaneous injections of adalimumab 40 mg and did not relapse.¹² Another patient with granulomatous cheilitis responded to adalimumab after corticosteroids, intralesional injections of triamcinolone, topical tacrolimus, roxithromycin, and clofazimine failed.¹⁷ The patient received adalimumab 80 mg for the first week and 40 mg for the second week and every 2 weeks thereafter. The patient began improving after the third dose and remained relapse free for at least 6 months of follow-up.¹⁷

Conclusion

We present a case of a 69-year-old woman who presented with facial nerve palsy, facial edema, and a fissured tongue, which is the classic triad of MRS, and all 3 symptoms improved with adalimumab.

Postpartum psychosis is a psychiatric emergency that can endanger the life of the mother and the newborn child if untreated. About 1 to 2 mothers in 1,000 experiences postpartum psychosis after delivery.¹ This rate is much higher among women with an established diagnosis of bipolar disorder before pregnancy.¹

Expedient recognition, diagnosis, and referral to a high-level psychiatric facility (usually a locked inpatient unit) are critical for ensuring the safety of mother and infant. A diligent medical workup followed by thorough education for the patient and family are important steps in caring for patients with postpartum psychosis. Close mental health follow-up, pharmacologic interventions, informed decision making regarding breastfeeding, and preserving the sleep-wake cycle are critical for stabilization.²

The authors present the case of a patient admitted to VA Central California Health Care System (VACCHCS) with postpartum psychosis and a discussion on existing research on the prevalence of postpartum psychosis, relevant risk factors, the association with bipolar disorder, and treatment strategies.

Case Presentation

A 31-year-old active-duty female with no history of mental illness was admitted to the psychiatric unit because new-onset disorganized behavior was preventing her from functioning at her workplace. Two weeks after giving birth to her second child, the patient began exhibiting an uncharacteristic, debilitating labile mood and disorganized behavior. Her supervisors required her to present for medical attention about 3 months after the birth of her child. She was transferred to VACCHCS for higher level medical care on military orders. The patient’s husband initially attributed these psychiatric symptoms to vocational stress and taking care of 2 young children. He observed the patient exhibiting tearfulness about her job, which quickly alternated with euphoric episodes of singing and dancing at inappropriate times, such as when the children had quieted down and were being prepared to go to bed.

At the initial psychiatric evaluation after transfer to VACCHCS, the patient appeared well-kept and slightly overweight. In general her appearance was unremarkable. Throughout the examination she sang both subtly and loudly and at times was confrontational and irritable.

She related oddly and often was guarded and difficult to engage; she sang and played with her blanket in a childlike way. She smiled and laughed inappropriately, mumbled incoherently to herself, scanned the room suspiciously, and often made intense eye contact. Her affect was labile, both tearful and euphoric at several points in the examination. Her thought process was tangential, illogical, grandiose, difficult to redirect, and with loose associations. Her thought content consisted of delusions (“I’ve got the devil on my back”) and grandiosity (“I am everyone, I am you…the president, the mayor”), and she often stated that she planned to become a singer or performer.

The patient claimed she was neither suicidal nor had thoughts of infanticide. She reported having no visual and auditory hallucinations but often seemed to be responding to internal stimuli: She mumbled to herself and looked intensely at parts of the room. Cognitively, the patient was fully intact to recent and remote events but displayed a poor attention span. She did not exhibit any motor abnormalities, such as tremor, rigidity, weakness, sensory loss, or abnormal gait.

The patient’s workup included full chemistry, complete blood count, thyroid-stimulating hormone, antithyroid antibodies, calcium, rapid plasma reagin to rule out syphilis, toxicology, folate, vitamin B₁₂, and vitamin D. All laboratory results were negative or within normal limits, although the urine drug screen was positive for cannabis. The patient’s husband noted that his wife never used cannabis except the weekend before her admission, when she impulsively went dancing, which was out of character for her. Her psychotic symptoms had been present weeks before the cannabis use; therefore, the her symptoms could not be attributed to a substance-induced psychotic disorder. A test for synthetic cannabis derivatives was negative. Newer synthetic compounds can cause more severe substance-induced psychotic symptoms than those of cannabis.³

The patient was diagnosed with postpartum psychosis and was started on the oral antipsychotic olanzapine 10 mg at bedtime. Additional doses were administered to control ongoing symptoms, which included a disorganized thought process; loose associations; euphoria; grandiosity; delusional content, such as “You are just a tool in place to help me;” reports of feeling as though she were in “outer space, outside in the galaxy;” decreased need for sleep; and irritability. The patient spent an entire interview with her eyes closed, stating that she could “hear” better because she was overstimulated if her eyes were open. She also described olfactory hallucinations of “strong perfume,” which the 2 providers present could not detect.

Olanzapine was not well tolerated because of sedation and was discontinued in favor of risperidone, 2 mg twice daily. Risperidone was more effective and better tolerated. Lithium was initiated the next day with target dosing at 300 mg in the morning and 600 mg at night. The patient became capable of linear, organized discussion and planning but remained euphoric with high energy; she exhibited grandiosity with frequent singing and dancing throughout her hospital stay. She often described her mood as “good, excellent, exuberant, exciting,” perseverating on the way words sounded and giggling in a childlike manner. She continued to have intrusive dreams of “hell and the devil” and that she was killed by gunshot.

The patient was continued on lithium and risperidone and transferred to a larger military hospital for further inpatient management, respecting military orders. Before discharge, a family conference was held with the patient and her husband to educate them on the importance of continued treatment, close follow-up, regular sleep patterns, and not breastfeeding while taking the prescribed medications. Although she was not back to her baseline at the time of transfer, the patient had stabilized significantly and gained sufficient insight into her condition.

Discussion

Postpartum psychosis can present with a prodromal phase consisting of fatigue, insomnia, restlessness, tearfulness, and emotional lability, making early identification difficult. Later, florid psychotic symptoms can include suspiciousness, confusion, incoherence, irrational statements, obsessive concern about the infant’s health, and delusions, including a belief that the baby is dead or defective. Some women might deny that the birth occurred or feel that they are unmarried, virginal, or persecuted.¹ More concerning symptoms include auditory hallucinations commanding the mother to harm or kill the infant and/or herself. Symptoms often begin within days to weeks of birth, usually 2 to 3 weeks after delivery but can occur as long as 8 weeks postpartum.¹ Several cases of infanticide and suicide have been documented.¹ The risk of experiencing another psychotic episode in subsequent pregnancies can be as high as 50%.^4-6 Regardless of symptom severity at onset, postpartum psychosis is a psychiatric emergency and must be treated as such.

Bipolar Disorder and Postpartum Psychosis

A close relationship exists between postpartum psychosis and development of bipolar disorder. A postpartum psychotic episode often is the harbinger of bipolar illness.⁷ About two-thirds of women who have an episode of postpartum psychosis will experience an underlying affective disorder within a year of childbirth.^1,8 It is unclear what triggers the psychotic episode, but it has been theorized that major systemic shifts in hormone levelsor trauma of delivery could instigate development of symptoms.^1,9

Risk factors include obstetric complications; perinatal infant mortality; previous episodes of bipolar disorder, psychosis, or postpartum psychosis; family history of bipolar disorder or postpartum psychosis; sleep deprivation; increased environmental stress; and lack of partner support.¹⁰ The strongest risk factor for developing postpartum psychosis is a personal or family history of bipolar disorder or a related psychotic disorder.¹¹ This risk factor is identified in about 40% to 50% cases of postpartum psychosis.¹¹

Treatment

Standard treatment for postpartum psychosis includes an antipsychotic and often lithium and benzodiazepines.^1,7,10,11 This treatment approach differs slightly from treating a patient with a nonpostpartum psychotic illness, who generally would not receive mood stabilizers, such as lithium. Including a mood stabilizer for postpartum psychosis is warranted because of the association between postpartum psychosis and bipolar disorder, which is treated with a mood stabilizer.

Prevalence

Postpartum psychosis is identified in 1 to 2 per 1,000 childbirths. In women who have had an earlier episode of postpartum psychosis or have a diagnosis of bipolar disorder, the rate is up to 100 times higher.¹ Kendell and colleagues found that psychiatric admissions occurred at a rate 7 times higher in the 30 days after birth than in the prepregnancy period, suggesting that metabolic factors might be involved in triggering postpartum psychotic symptoms.¹² An abrupt hormonal loss occurs at childbirth; hormones peak 200-fold during gestation and decline rapidly within a day after birth.⁹ Despite the severity of symptoms in postpartum psychosis, these patients tend to have a better prognosis than that of women with psychotic episodes not related to pregnancy.⁴

Patients with bipolar disorder have the highest risk of psychotic episodes during the postpartum period, with a study reporting 260 episodes of psychosis per deliveries among women with bipolar disorder.¹³ Studies such as this suggest that episodes of postpartum psychosis might be a variant or atypical presentation of an underlying bipolar disorder or a predisposition to developing the disorder.¹⁴ In a study that compared 58 patients with postpartum psychosis with to 52 individuals with nonchildbearing-related psychosis, manic symptoms were more common among the postpartum group.¹⁵ Family studies have shown that the risk of psychiatric illness among first-degree relatives of women with postpartum psychosis is 10% to 50%, which is higher than in the general population.¹⁴

Brockington and colleagues found that patients with postpartum psychosis had more mood lability, distractibility, and confusion than those with psychosis unrelated to pregnancy.¹⁵ Patients with postpartum psychosis were more likely to have impaired sensorium, bizarre quality of delusions, and memory loss. Psychosis with onset after childbirth included high levels of thought disorganization, delusions of reference, delusions of persecution, and greater levels of homicidal ideation and behavior.¹⁶ This study also reported symptoms such as visual, tactile, and olfactory hallucinations and a presentation similar to that of delirium.

Chandra and colleagues found that 53% of women with postpartum psychosis had delusions about the infant, including beliefs that someone would harm or kill the baby or that the baby would be harmed by their breast milk.¹⁷ Compared with women with bipolar disorder, Oostheuizen and colleagues found that women with postpartum psychosis had delusions of control, such as feeling under the influence of an overpowering force that controlled their actions.¹⁸ Infanticidal thoughts are common among patients with postpartum psychosis, and about 4% of women committed infanticide.¹

Rapid stabilization and treatment are important because postpartum psychosis is considered a psychiatric emergency.⁷ Potential consequences of delayed diagnosis and treatment include harm or death of the infant by infanticide and death of the mother by suicide. A thorough physical examination is important to rule out metabolic or neuroendocrine causes of psychosis other than postpartum hormonal shifts. These could include causes of altered mental status: stroke, pulmonary embolism, amniotic fluid emboli, Sheehan syndrome, thyroid disorders, electrolyte abnormalities, acute hemorrhage, sepsis, and substance toxicity or withdrawal.¹⁰ A complete blood count, full chemistry, thyroid function tests, antithyroid antibody tests, calcium, vitamin B₁₂, and folate should be measured.^7,10

Initial treatment should include antipsychotics and often mood stabilizers such as lithium. Managing insomnia aggressively is also necessary for initial stabilization and to prevent a repeat manic episode if the patient develops bipolar disorder.² Many experts argue that sleep loss in combination with other risk factors might be the final common pathway for development of postpartum psychosis in women predisposed to this disorder.^19,20

Treating insomnia in an outpatient setting includes teaching sleep hygiene practices and relaxation techniques. Although these methods to regulate sleep could be encouraged during the emergent inpatient stabilization of a patient with postpartum psychosis, pharmacologic approaches are necessary for acute mania and psychosis. Concern about possible dependence on benzodiazepines and other sedating sleep aids are valid; however, the benefit of acute stabilization of psychotic symptoms outweighs the potential risk of dependence.

Typically, first-line treatment is an antipsychotic, and second-generation antipsychotics generally are preferred over first-generation antipsychotics because of their more benign adverse effect profile.^21,22 There are no controlled trials that compare antipsychotics with placebo or other interventions for postpartum psychosis. Therefore, use of atypical antipsychotics is based on randomized trials demonstrating efficacy in reducing psychosis in bipolar disorder, depression with psychotic features, and schizoaffective disorder.^23,24 Once the patient is treated with an antipsychotic, further use of psychotropic medications, such as lithium or other mood stabilizers, should be based on the patient’s clinical presentation. For example, the patient in this case study primarily had manic symptoms consistent with bipolar disorder, making lithium or another mood stabilizer an appropriate choice.

Bergink and colleagues demonstrated positive outcomes with a treatment algorithm involving sequential use of benzodiazepines to improve sleep, an antipsychotic to decrease acute manic symptoms, lithium to stabilize mood based on symptoms, and electroconvulsive therapy if other treatments were not successful.²⁵ Case studies document that administering estrogen led to recovery from postpartum psychosis, although patients often relapsed when estrogen was stopped.²⁶ Electroconvulsive therapy has shown promising results, especially in patients who do not respond to antipsychotic medications or lithium.^27,28

Antipsychotic and Other Psychotropic Medications

Choice of an antipsychotic and other psychotropic medications to treat postpartum psychosis is based on the patient’s breastfeeding status. The benefits of treatment should be weighed against the risks of a breastfeeding infant’s exposure to the medication. Because postpartum psychosis is a psychiatric emergency, the benefits of the medication are considered to outweigh any potential adverse effect to the breastfeeding infant exposed to the medication. Risks of untreated postpartum psychosis to the infant include rejection of the infant, poor parental relationships, suicide, infanticide, long-term failure to bond with the child, delayed infant development, and failure to thrive.²⁹ Also, many mothers—including the patient in this presentation—decide that the benefits of treatment outweigh those of breastfeeding and choose to feed their infant with formula. Even if the patient chooses to bottle-feed her infant, consider administering medications that are considered safer for breastfeeding because the patient may need to continue the psychotropic during later pregnancies to prevent future psychotic episodes.³⁰ All psychotropic medications pass into breast milk.²⁹ Studies on the long-term effect of these medications on the infant are limited, but experts tend to recommend olanzapine, quetiapine, and risperidone over aripiprazole and ziprasidone.^21,31-33

Lithium often is used to treat postpartum psychosis. Studies examining risk to the infant after long-term exposure to lithium through breast milk have not been conducted, but the American Academy of Pediatrics discourages its use during breastfeeding because of concerns about toxicity in the infant.^34-36

Sleep regulation is important to treat bipolar disorder and to prevent future episodes.^2,20,21 To ensure safety of the infant and mother before discharge, family education is imperative to establish close follow-up, adequate sleep, and reduction of stressors.^7,10 Separation from the infant might be necessary after discharge, and someone should monitor the infant at all times until the outpatient mental health provider confirms that all psychotic symptoms have resolved.^7,10 Successful treatment of postpartum psychosis requires close communication among the mental health provider, the pediatrician, and the obstetrician or women’s health provider.¹⁰ Because a close-knit team approach after discharge from the acute psychiatric unit is necessary, the care of such a patient and her child provides an educational opportunity for individuals working in integrated care clinics.

Conclusion

Postpartum psychosis is a psychiatric emergency requiring immediate treatment to prevent dire outcomes such as suicide or infanticide. Treatment considerations include the cost-benefit analysis of breastfeeding and the toxicity of psychotropic medications when ingested by the infant via breast milk. A close relationship has been demonstrated between postpartum psychosis and bipolar disorder.

Preferred treatment regimens include lithium and an antipsychotic. Educate the family as a unit about the diagnosis and treatment, the importance of adequate sleep for treatment and prophylaxis, and the decision on whether to discontinue breastfeeding despite its well-known benefits for mother and infant. Stabilization is a multifaceted process and needs to be reinforced with a solid plan for support and follow-up appointments. Because of the higher risk of relapse, educate patients about prophylactic treatment during subsequent pregnancies and monitor for development of bipolar disorder in the future.

Postpartum psychosis is a psychiatric emergency that can endanger the life of the mother and the newborn child if untreated. About 1 to 2 mothers in 1,000 experiences postpartum psychosis after delivery.¹ This rate is much higher among women with an established diagnosis of bipolar disorder before pregnancy.¹

Expedient recognition, diagnosis, and referral to a high-level psychiatric facility (usually a locked inpatient unit) are critical for ensuring the safety of mother and infant. A diligent medical workup followed by thorough education for the patient and family are important steps in caring for patients with postpartum psychosis.

The patient became capable of linear, organized discussion and planning but remained euphoric with high energy; she exhibited grandiosity with frequent singing and dancing throughout her hospital stay. She often described her mood as “good, excellent, exuberant, exciting,” perseverating on the way words sounded and giggling in a childlike manner. She continued to have intrusive dreams of “hell and the devil” and that she was killed by gunshot.

The patient was continued on lithium and risperidone and transferred to a larger military hospital for further inpatient management, respecting military orders. Before discharge, a family conference was held with the patient and her husband to educate them on the importance of continued treatment, close follow-up, regular sleep patterns, and not breastfeeding while taking the prescribed medications. Although she was not back to her baseline at the time of transfer, the patient had stabilized significantly and gained sufficient insight into her condition.

Discussion

Postpartum psychosis can present with a prodromal phase consisting of fatigue, insomnia, restlessness, tearfulness, and emotional lability, making early identification difficult. Later, florid psychotic symptoms can include suspiciousness, confusion, incoherence, irrational statements, obsessive concern about the infant’s health, and delusions, including a belief that the baby is dead or defective. Some women might deny that the birth occurred or feel that they are unmarried, virginal, or persecuted.¹ More concerning symptoms include auditory hallucinations commanding the mother to harm or kill the infant and/or herself. Symptoms often begin within days to weeks of birth, usually 2 to 3 weeks after delivery but can occur as long as 8 weeks postpartum.¹ Several cases of infanticide and suicide have been documented.¹ The risk of experiencing another psychotic episode in subsequent pregnancies can be as high as 50%.^4-6 Regardless of symptom severity at onset, postpartum psychosis is a psychiatric emergency and must be treated as such.

Bipolar Disorder and Postpartum Psychosis

A close relationship exists between postpartum psychosis and development of bipolar disorder. A postpartum psychotic episode often is the harbinger of bipolar illness.⁷ About two-thirds of women who have an episode of postpartum psychosis will experience an underlying affective disorder within a year of childbirth.^1,8 It is unclear what triggers the psychotic episode, but it has been theorized that major systemic shifts in hormone levelsor trauma of delivery could instigate development of symptoms.^1,9

Risk factors include obstetric complications; perinatal infant mortality; previous episodes of bipolar disorder, psychosis, or postpartum psychosis; family history of bipolar disorder or postpartum psychosis; sleep deprivation; increased environmental stress; and lack of partner support.¹⁰ The strongest risk factor for developing postpartum psychosis is a personal or family history of bipolar disorder or a related psychotic disorder.¹¹ This risk factor is identified in about 40% to 50% cases of postpartum psychosis.¹¹

Treatment

Standard treatment for postpartum psychosis includes an antipsychotic and often lithium and benzodiazepines.^1,7,10,11 This treatment approach differs slightly from treating a patient with a nonpostpartum psychotic illness, who generally would not receive mood stabilizers, such as lithium. Including a mood stabilizer for postpartum psychosis is warranted because of the association between postpartum psychosis and bipolar disorder, which is treated with a mood stabilizer.

Prevalence

Postpartum psychosis is identified in 1 to 2 per 1,000 childbirths. In women who have had an earlier episode of postpartum psychosis or have a diagnosis of bipolar disorder, the rate is up to 100 times higher.¹ Kendell and colleagues found that psychiatric admissions occurred at a rate 7 times higher in the 30 days after birth than in the prepregnancy period, suggesting that metabolic factors might be involved in triggering postpartum psychotic symptoms.¹² An abrupt hormonal loss occurs at childbirth; hormones peak 200-fold during gestation and decline rapidly within a day after birth.⁹ Despite the severity of symptoms in postpartum psychosis, these patients tend to have a better prognosis than that of women with psychotic episodes not related to pregnancy.⁴

Patients with bipolar disorder have the highest risk of psychotic episodes during the postpartum period, with a study reporting 260 episodes of psychosis per deliveries among women with bipolar disorder.¹³ Studies such as this suggest that episodes of postpartum psychosis might be a variant or atypical presentation of an underlying bipolar disorder or a predisposition to developing the disorder.¹⁴ In a study that compared 58 patients with postpartum psychosis with to 52 individuals with nonchildbearing-related psychosis, manic symptoms were more common among the postpartum group.¹⁵ Family studies have shown that the risk of psychiatric illness among first-degree relatives of women with postpartum psychosis is 10% to 50%, which is higher than in the general population.¹⁴

Brockington and colleagues found that patients with postpartum psychosis had more mood lability, distractibility, and confusion than those with psychosis unrelated to pregnancy.¹⁵ Patients with postpartum psychosis were more likely to have impaired sensorium, bizarre quality of delusions, and memory loss. Psychosis with onset after childbirth included high levels of thought disorganization, delusions of reference, delusions of persecution, and greater levels of homicidal ideation and behavior.¹⁶ This study also reported symptoms such as visual, tactile, and olfactory hallucinations and a presentation similar to that of delirium.

Chandra and colleagues found that 53% of women with postpartum psychosis had delusions about the infant, including beliefs that someone would harm or kill the baby or that the baby would be harmed by their breast milk.¹⁷ Compared with women with bipolar disorder, Oostheuizen and colleagues found that women with postpartum psychosis had delusions of control, such as feeling under the influence of an overpowering force that controlled their actions.¹⁸ Infanticidal thoughts are common among patients with postpartum psychosis, and about 4% of women committed infanticide.¹

Rapid stabilization and treatment are important because postpartum psychosis is considered a psychiatric emergency.⁷ Potential consequences of delayed diagnosis and treatment include harm or death of the infant by infanticide and death of the mother by suicide. A thorough physical examination is important to rule out metabolic or neuroendocrine causes of psychosis other than postpartum hormonal shifts. These could include causes of altered mental status: stroke, pulmonary embolism, amniotic fluid emboli, Sheehan syndrome, thyroid disorders, electrolyte abnormalities, acute hemorrhage, sepsis, and substance toxicity or withdrawal.¹⁰ A complete blood count, full chemistry, thyroid function tests, antithyroid antibody tests, calcium, vitamin B₁₂, and folate should be measured.^7,10

Initial treatment should include antipsychotics and often mood stabilizers such as lithium. Managing insomnia aggressively is also necessary for initial stabilization and to prevent a repeat manic episode if the patient develops bipolar disorder.² Many experts argue that sleep loss in combination with other risk factors might be the final common pathway for development of postpartum psychosis in women predisposed to this disorder.^19,20

Treating insomnia in an outpatient setting includes teaching sleep hygiene practices and relaxation techniques. Although these methods to regulate sleep could be encouraged during the emergent inpatient stabilization of a patient with postpartum psychosis, pharmacologic approaches are necessary for acute mania and psychosis. Concern about possible dependence on benzodiazepines and other sedating sleep aids are valid; however, the benefit of acute stabilization of psychotic symptoms outweighs the potential risk of dependence.

Typically, first-line treatment is an antipsychotic, and second-generation antipsychotics generally are preferred over first-generation antipsychotics because of their more benign adverse effect profile.^21,22 There are no controlled trials that compare antipsychotics with placebo or other interventions for postpartum psychosis. Therefore, use of atypical antipsychotics is based on randomized trials demonstrating efficacy in reducing psychosis in bipolar disorder, depression with psychotic features, and schizoaffective disorder.^23,24 Once the patient is treated with an antipsychotic, further use of psychotropic medications, such as lithium or other mood stabilizers, should be based on the patient’s clinical presentation. For example, the patient in this case study primarily had manic symptoms consistent with bipolar disorder, making lithium or another mood stabilizer an appropriate choice.

Bergink and colleagues demonstrated positive outcomes with a treatment algorithm involving sequential use of benzodiazepines to improve sleep, an antipsychotic to decrease acute manic symptoms, lithium to stabilize mood based on symptoms, and electroconvulsive therapy if other treatments were not successful.²⁵ Case studies document that administering estrogen led to recovery from postpartum psychosis, although patients often relapsed when estrogen was stopped.²⁶ Electroconvulsive therapy has shown promising results, especially in patients who do not respond to antipsychotic medications or lithium.^27,28

Antipsychotic and Other Psychotropic Medications

Choice of an antipsychotic and other psychotropic medications to treat postpartum psychosis is based on the patient’s breastfeeding status. The benefits of treatment should be weighed against the risks of a breastfeeding infant’s exposure to the medication. Because postpartum psychosis is a psychiatric emergency, the benefits of the medication are considered to outweigh any potential adverse effect to the breastfeeding infant exposed to the medication. Risks of untreated postpartum psychosis to the infant include rejection of the infant, poor parental relationships, suicide, infanticide, long-term failure to bond with the child, delayed infant development, and failure to thrive.²⁹ Also, many mothers—including the patient in this presentation—decide that the benefits of treatment outweigh those of breastfeeding and choose to feed their infant with formula. Even if the patient chooses to bottle-feed her infant, consider administering medications that are considered safer for breastfeeding because the patient may need to continue the psychotropic during later pregnancies to prevent future psychotic episodes.³⁰ All psychotropic medications pass into breast milk.²⁹ Studies on the long-term effect of these medications on the infant are limited, but experts tend to recommend olanzapine, quetiapine, and risperidone over aripiprazole and ziprasidone.^21,31-33

Lithium often is used to treat postpartum psychosis. Studies examining risk to the infant after long-term exposure to lithium through breast milk have not been conducted, but the American Academy of Pediatrics discourages its use during breastfeeding because of concerns about toxicity in the infant.^34-36

Sleep regulation is important to treat bipolar disorder and to prevent future episodes.^2,20,21 To ensure safety of the infant and mother before discharge, family education is imperative to establish close follow-up, adequate sleep, and reduction of stressors.^7,10 Separation from the infant might be necessary after discharge, and someone should monitor the infant at all times until the outpatient mental health provider confirms that all psychotic symptoms have resolved.^7,10 Successful treatment of postpartum psychosis requires close communication among the mental health provider, the pediatrician, and the obstetrician or women’s health provider.¹⁰ Because a close-knit team approach after discharge from the acute psychiatric unit is necessary, the care of such a patient and her child provides an educational opportunity for individuals working in integrated care clinics.

Conclusion

Postpartum psychosis is a psychiatric emergency requiring immediate treatment to prevent dire outcomes such as suicide or infanticide. Treatment considerations include the cost-benefit analysis of breastfeeding and the toxicity of psychotropic medications when ingested by the infant via breast milk. A close relationship has been demonstrated between postpartum psychosis and bipolar disorder.

Preferred treatment regimens include lithium and an antipsychotic. Educate the family as a unit about the diagnosis and treatment, the importance of adequate sleep for treatment and prophylaxis, and the decision on whether to discontinue breastfeeding despite its well-known benefits for mother and infant. Stabilization is a multifaceted process and needs to be reinforced with a solid plan for support and follow-up appointments. Because of the higher risk of relapse, educate patients about prophylactic treatment during subsequent pregnancies and monitor for development of bipolar disorder in the future.

THE CASE

A 25-year-old man, who was an active duty US Navy sailor, went to his ship’s medical department complaining of a mild cough that he’d had for 2 days. He denied having any fevers, chills, night sweats, angina, or dyspnea. He said he hadn’t experienced any exertional fatigue or difficulty completing the rigorous physical tasks of his occupation as an engineman on the ship. The patient had no medical or surgical history of significance, and he wasn’t taking any medications or supplements.

On exam, he was not in acute distress and his vital signs were within normal limits. Auscultation revealed mild wheezing throughout the upper lung fields and loud heart sounds throughout his chest that were audible even with gentle contact of the stethoscope diaphragm. He had no discernible murmurs, rubs, or gallops.

In light of the unusually loud heart sounds heard on exam, we performed an electrocardiogram. The EKG revealed a normal sinus rhythm, slight right axis deviation indicated by tall R-waves in V1 (also suggestive of right ventricular hypertrophy), an incomplete right bundle branch block, and a crochetage sign (a notch in the R-waves of the inferior leads).¹ A chest x-ray (FIGURE 1) revealed a normal-sized heart and dilated pulmonary vasculature suggestive of pulmonary hypertension.

THE DIAGNOSIS

To further evaluate the cardiopulmonary findings, ultrasound studies (transthoracic and transesophageal echocardiography) were performed. These demonstrated a very large secundum-type atrial septal defect (ASD), measuring at its largest point about 30 × 48 mm (FIGURE 2 and FIGURE 3C). Doppler flow analysis and a bubble study (VIDEOS 1 and 2) demonstrated significant shunting across the ASD. Gated cardiac computed tomography (CT) was also used to characterize the ASD (FIGURE 3). It revealed that the superior and posterior rims of the ASD were essentially absent and that the right atrium and ventricle were severely enlarged, while the left chambers were normal in size and function with an ejection fraction >55%. The notching of the R-waves of the inferior leads, seen in our patient’s EKG, is typically seen with large ASDs.^1,2

DISCUSSION

ASDs are typically uncovered on exam via auscultation of heart sounds, which might reveal a split of the second heart sound (S2) and diastolic murmurs. ASDs are typically classified by size, and their management depends on this factor, along with the patient’s age and symptoms. In children with small defects (<6 mm), treatment usually consists of conservative observation, as more than half of these ASDs will spontaneously close.³ But, as children age, they are more likely to engage in exertional activity (work, recreational sports) and an unrepaired ASD may yield symptoms (angina, dyspnea, fatigue, other cardiopulmonary strain). With such symptoms and when closure is not spontaneously achieved by adolescence or adulthood, an invasive approach is often necessary to correct the defect.

ASD repair. Traditionally, repair has involved some form of open thoracotomy. More recently, several minimally invasive techniques have been developed. Catheter-based device closure, in which a catheter is percutaneously guided to the defect and a patch is deployed to seal the ASD, is a technique that has been shown to successfully correct large ASDs of up to 40 mm in size.⁴ Robotic procedures have also been developed to correct ASDs through much smaller incisions.⁵ Both of these techniques require a significant rim of residual septal tissue around the defect.

Individualized approach. Since our patient had a rather large ASD that did not have sufficient residual septal rim tissue, percutaneous and robotic approaches were not feasible. Instead, he required more invasive cardiothoracic surgery. In cases such as this, the exact technique and type of incision (sternotomy vs access through the lateral chest wall) depend on age, gender, and the presence of other comorbidities.⁶

Our patient. Because there was concern that any approach other than a median one might not afford enough space to fix an ASD of such considerable size, our patient underwent a median sternotomy by a pediatric cardiothoracic surgeon who specialized in these repairs (in children as well as young adults). During the procedure, the ASD was accessed and confirmed to be as large as predicted by diagnostic imaging. A surgical patch was sutured in place to correct the defect. There were no intra-operative or postop complications.

Four weeks later, the patient had a mild pericardial effusion that was managed medically with daily furosemide and aspirin. At his 8-week postop appointment, the fluid accumulation had resolved, and he was completely asymptomatic. The patient returned to full-time active duty in the US Navy.

THE TAKEAWAY

Adults with rather large ASDs can present in a relatively asymptomatic manner and report none of the classic complaints (angina, dyspnea, fatigue). They may even engage in heavy exertional activity with no difficulty. The underlying defect may be discovered incidentally on exam by noting a split of the S2 on auscultation. If pulmonary hypertension exists, the clinician may also note a loud S2. An exam that raises suspicion for an ASD can then be followed by tests that solidify the diagnosis. Surgery is usually necessary to correct an ASD in an adult who is symptomatic or exhibits significant cardiopulmonary strain.

THE CASE

A 34-year-old woman was referred to the hepatology clinic for evaluation of an increased serum alkaline phosphatase (ALP) level. She was gravida 5 and in her 38th week of gestation. Her obstetric history was significant for 2 uncomplicated spontaneous term vaginal deliveries resulting in live births and 2 spontaneous abortions. The patient reported generalized pruritus for 2 months prior to the visit. She had no comorbidities and denied any other symptoms. She reported no family history of liver disease or complications during pregnancy in relatives. The patient did not smoke or drink, and had come to our hospital for her prenatal care visits.

The physical exam revealed normal vital signs, no jaundice, a gravid uterus, and acanthosis nigricans on the neck and axilla with scattered excoriations on the arms, legs, and abdomen. Her serum ALP level was 1093 U/L (normal: 50-136 U/L). Immediately before this pregnancy, her serum ALP had been normal at 95 U/L, but it had since been increasing with a peak value of 1134 U/L by 37 weeks’ gestation. Serum transaminase activities and albumin and bilirubin concentrations were normal, as was her prothrombin time. The rest of her lab tests were also normal, including her fasting serum bile acid concentration, which was 9 mcmol/L (normal: 4.5-19.2 mcmol/L).

THE DIAGNOSIS

Although cholestasis of pregnancy was considered, the patient’s markedly elevated serum ALP level suggested the presence of another cholestatic liver disease. Additional tests revealed an antimitochondrial antibody (AMA) titer of 1:320 (normal: <1:20) and immunoglobulin A, G, and M levels within normal limits. Accordingly, we diagnosed primary biliary cholangitis (PBC).

The patient delivered vaginally at another institution uneventfully and returned to the hepatology clinic 7 months postpartum. Repeat laboratory tests (TABLE) revealed increased AMA titer and immunoglobulin M levels from baseline (38 weeks’ gestation). The physical exam was notable for the absence of both jaundice and stigmata of chronic liver disease. A liver ultrasound was normal. The patient still reported pruritus, as well as a new symptom—fatigue. A liver biopsy was performed, and findings were consistent with PBC, stage 1 (FIGURE).

PBC, historically known as primary biliary cirrhosis, is a chronic, likely immune-mediated, cholestatic liver disease characterized by the progressive inflammatory destruction of intrahepatic bile ducts. The disease has a female to male predominance of 10:1, with age of diagnosis most often between 40 and 50 years, although about a quarter of female patients present during their reproductive years.^1,2

PBC in pregnant women

During pregnancy, the profound physiologic changes and adaptations in the endocrine, metabolic, and immune systems that are necessary for normal fetal development can affect the maternal hepatobiliary system. In patients with prior autoimmune liver disease, the liver is known to adapt itself to these physiologic changes by entering a state of immune tolerance. This is induced by relative hypercortisolism, a shift from predominantly cell-mediated immunity to humoral immunity, and inhibition of T-cell activation. These changes can result in remission of autoimmune disease activity during pregnancy and postpartum flaring when these protective mechanisms are lost (although neither remission nor postpartum flaring occurred in this patient’s case).^1-3

While a well-compensated state is associated with better fetal and maternal outcomes than a decompensated condition, cirrhosis is not a contraindication to pregnancy. Vaginal delivery is generally safe for patients with PBC, and studies have reported no childbirth complications or adverse maternal outcomes.^1,3,4

The approved treatment for PBC, ursodeoxycholic acid (UDCA), was classified as a category B agent according to the Food and Drug Administration’s now defunct classification system for drugs used during pregnancy and lactation. It’s considered to be the treatment of choice for intrahepatic cholestasis of pregnancy, but there are no recommendations for its use in pregnant patients with PBC. Several studies have observed no significant teratogenic effect in babies whose mothers were treated with UDCA for PBC during pregnancy.^1-4 Postpartum, 60% to 70% of PBC patients have been reported to exhibit biochemical disease activity,^1,3 and in one case, a liver transplant was required due to liver failure.⁵

Look for AMA, elevated ALP

The diagnosis of the disease in this case was made by the detection of AMA, which has a specificity of 98% for PBC. However, isolated instances of the presence of AMA are not uncommon; they have been documented in up to 64% of healthy individuals.⁶ In addition, while one would expect to see a 2- to 4-fold rise in ALP levels during pregnancy (due to placental isoenzyme production),^2,7 our patient’s serum ALP level was much higher, suggesting probable cholestatic liver disease such as PBC. The diagnosis in this case was confirmed by liver biopsy.

Our patient was started on UDCA 13 to 15 mg/kg/d. She remained clinically stable at subsequent follow-ups.

THE TAKEAWAY

Typically seen in middle-aged women, PBC can be detected by the presence of AMA and elevated ALP levels. Pregnant patients with chronic liver disease, including PBC, should be followed by a hepatologist and a high-risk obstetrician. They should be carefully monitored and frequently reassessed throughout the pregnancy, delivery, and postpartum period, even though studies have documented favorable outcomes for both mother and baby.^1,3,4

Vaginal delivery is generally safe for patients with PBC, and studies have reported no childbirth complications or adverse maternal outcomes.^1,3,4

The approved treatment for PBC, ursodeoxycholic acid (UDCA), was classified as a category B agent according to the Food and Drug Administration’s now defunct classification system for drugs used during pregnancy and lactation. It’s considered to be the treatment of choice for intrahepatic cholestasis of pregnancy, but there are no recommendations for its use in pregnant patients with PBC. Several studies have observed no significant teratogenic effect in babies whose mothers were treated with UDCA for PBC during pregnancy.^1-4 Postpartum, 60% to 70% of PBC patients have been reported to exhibit biochemical disease activity,^1,3 and in one case, a liver transplant was required due to liver failure.⁵

Look for AMA, elevated ALP

The diagnosis of the disease in this case was made by the detection of AMA, which has a specificity of 98% for PBC. However, isolated instances of the presence of AMA are not uncommon; they have been documented in up to 64% of healthy individuals.⁶ In addition, while one would expect to see a 2- to 4-fold rise in ALP levels during pregnancy (due to placental isoenzyme production),^2,7 our patient’s serum ALP level was much higher, suggesting probable cholestatic liver disease such as PBC. The diagnosis in this case was confirmed by liver biopsy.

Our patient was started on UDCA 13 to 15 mg/kg/d. She remained clinically stable at subsequent follow-ups.

THE TAKEAWAY

Typically seen in middle-aged women, PBC can be detected by the presence of AMA and elevated ALP levels. Pregnant patients with chronic liver disease, including PBC, should be followed by a hepatologist and a high-risk obstetrician. They should be carefully monitored and frequently reassessed throughout the pregnancy, delivery, and postpartum period, even though studies have documented favorable outcomes for both mother and baby.^1,3,4

THE CASE

A 34-year-old woman was referred to the hepatology clinic for evaluation of an increased serum alkaline phosphatase (ALP) level. She was gravida 5 and in her 38th week of gestation. Her obstetric history was significant for 2 uncomplicated spontaneous term vaginal deliveries resulting in live births and 2 spontaneous abortions. The patient reported generalized pruritus for 2 months prior to the visit. She had no comorbidities and denied any other symptoms. She reported no family history of liver disease or complications during pregnancy in relatives. The patient did not smoke or drink, and had come to our hospital for her prenatal care visits.

The physical exam revealed normal vital signs, no jaundice, a gravid uterus, and acanthosis nigricans on the neck and axilla with scattered excoriations on the arms, legs, and abdomen. Her serum ALP level was 1093 U/L (normal: 50-136 U/L). Immediately before this pregnancy, her serum ALP had been normal at 95 U/L, but it had since been increasing with a peak value of 1134 U/L by 37 weeks’ gestation. Serum transaminase activities and albumin and bilirubin concentrations were normal, as was her prothrombin time. The rest of her lab tests were also normal, including her fasting serum bile acid concentration, which was 9 mcmol/L (normal: 4.5-19.2 mcmol/L).

THE DIAGNOSIS

Although cholestasis of pregnancy was considered, the patient’s markedly elevated serum ALP level suggested the presence of another cholestatic liver disease. Additional tests revealed an antimitochondrial antibody (AMA) titer of 1:320 (normal: <1:20) and immunoglobulin A, G, and M levels within normal limits. Accordingly, we diagnosed primary biliary cholangitis (PBC).

The patient delivered vaginally at another institution uneventfully and returned to the hepatology clinic 7 months postpartum. Repeat laboratory tests (TABLE) revealed increased AMA titer and immunoglobulin M levels from baseline (38 weeks’ gestation). The physical exam was notable for the absence of both jaundice and stigmata of chronic liver disease. A liver ultrasound was normal. The patient still reported pruritus, as well as a new symptom—fatigue. A liver biopsy was performed, and findings were consistent with PBC, stage 1 (FIGURE).

PBC, historically known as primary biliary cirrhosis, is a chronic, likely immune-mediated, cholestatic liver disease characterized by the progressive inflammatory destruction of intrahepatic bile ducts. The disease has a female to male predominance of 10:1, with age of diagnosis most often between 40 and 50 years, although about a quarter of female patients present during their reproductive years.^1,2

PBC in pregnant women

During pregnancy, the profound physiologic changes and adaptations in the endocrine, metabolic, and immune systems that are necessary for normal fetal development can affect the maternal hepatobiliary system. In patients with prior autoimmune liver disease, the liver is known to adapt itself to these physiologic changes by entering a state of immune tolerance. This is induced by relative hypercortisolism, a shift from predominantly cell-mediated immunity to humoral immunity, and inhibition of T-cell activation. These changes can result in remission of autoimmune disease activity during pregnancy and postpartum flaring when these protective mechanisms are lost (although neither remission nor postpartum flaring occurred in this patient’s case).^1-3
