To the Editor:

A 56-year-old man with a history of opioid abuse and splenectomy decades prior due to a motor vehicle accident was brought to an outside emergency department with confusion, slurred speech, and difficulty breathing. Over the next few days, he became febrile and hypotensive, requiring vasopressors. Clinical laboratory testing revealed a urine drug screen positive for opioids and a low platelet count in the setting of a rapidly evolving retiform purpuric rash.

The patient was transferred to our institution 6 days after initial presentation with primary diagnoses of septic shock with multiorgan failure and disseminated intravascular coagulation (DIC). Blood cultures were positive for gram-negative rods. After several days of broad-spectrum antibiotics and supportive care, cultures were reported as positive for Capnocytophaga canimorsus. Upon further questioning, the patient’s wife reported that the couple had a new puppy and that the patient often allowed the dog to bite him playfully and lick abrasions on his hands and legs. He had not received medical treatment for any of the dog’s bites.

On initial examination at the time of transfer, the patient’s skin was remarkable for diffuse areas of stellate and retiform purpura with dusky centers and necrosis of the nasal tip and earlobes. Both hands were purpuric, with necrosis of the fingertips (Figure 1A). The flank was marked by large areas of full-thickness sloughing of the skin (Figure 1B). The lower extremities were edematous, with some areas of stellate purpura and numerous large bullae that drained straw-colored fluid (Figure 1C). Lower extremity pulses were found with Doppler ultrasonography.

Given the presence of rapidly developing retiform purpura in the clinical context of severe sepsis, purpura fulminans (PF) was the primary consideration in the differential diagnosis. Levamisole-induced necrosis syndrome also was considered because of necrosis of the ears and nose as well as the history of substance use; however, the patient was not known to have a history of cocaine abuse, and a test of antineutrophil cytoplasmic antibody was negative.

A punch biopsy of the abdomen revealed intravascular thrombi with epidermal and sweat gland necrosis, consistent with PF (Figure 2). Gram, Giemsa, and Gomori methenamine-silver stains were negative for organisms. Tissue culture remained negative. Repeat blood cultures demonstrated Candida parapsilosis fungemia. Respiratory culture was positive for budding yeast.

The patient was treated with antimicrobials, intravenous argatroban, and subcutaneous heparin. Purpura and bullae on the trunk slowly resolved with systemic therapy and wound care with petrolatum and nonadherent dressings. However, lesions on the nasal tip, all fingers of both hands, and several toes evolved into dry gangrene. The hospital course was complicated by renal failure requiring continuous renal replacement therapy; respiratory failure requiring ventilator support; and elevated levels of liver enzymes, consistent with involvement of the hepatic microvasculature.

The patient was in the medical intensive care unit at our institution for 2 weeks and was transferred to a burn center for specialized wound care. At transfer, he was still on a ventilator and receiving continuous renal replacement therapy. Subsequently, the patient required a left above-the-knee amputation, right below-the-knee amputation, and amputation of several digits of the upper extremities. In the months after the amputations, he required multiple stump revisions and experienced surgical site infections that complicated healing.

Purpura fulminans is an uncommon syndrome characterized by intravascular thrombosis and hemorrhagic infarction of the skin. The condition commonly is associated with septic shock, causing vascular collapse and DIC. It often develops rapidly.

Because of associated high mortality, it is important to differentiate PF from other causes of cutaneous retiform purpura, including other causes of thrombosis and large vessel vasculitis. Leading causes of PF include infection and hereditary or acquired deficiency of protein C, protein S, or antithrombin III. Regardless of cause, biopsy results demonstrate vascular thrombosis out of proportion to vasculitis. The mortality rate is 42% to 50%. The incidence of postinfectious sepsis sequelae in PF is higher than in survivors of sepsis only, especially amputation.^1-3 Most patients do not die from complications of sepsis but from sequelae of the hypercoagulable and prothrombotic state associated with PF.⁴ Hemorrhagic infarction can affect the kidneys, brain, lungs, heart, eyes, and adrenal glands (ie, necrosis, namely Waterhouse-Friderichsen syndrome).⁵

The most common infectious cause of PF is sepsis secondary to Neisseria meningitidis, with as many as 25% of infected patients developing PF.⁶Streptococcus pneumoniae is another common cause. Other important causative organisms include Streptococcus pyogenes; Staphylococcus aureus (in the setting of intravenous substance use); Klebsiella oxytoca; Klebsiella aerogenes; rickettsial organisms; and viruses, including cytomegalovirus and varicella-zoster virus.^2,7-13 Two earlier cases associated with Capnocytophaga were characterized by concomitant renal failure, metabolic acidosis, hemolytic anemia, and DIC.¹⁴

It is estimated that Capnocytophaga causes 11% to 46% of all cases of sepsis¹⁵; sepsis resulting from Capnocytophaga has extremely poor outcomes, with mortality reaching as high as 60%. The organism is part of the normal oral flora of cats and dogs, and a bite (less often, a scratch) is the cause of most Capnocytophaga infections. The clinical spectrum of C canimorsus infection associated with dog saliva exposure more commonly includes cellulitis at or around the site of inoculation, meningitis, and endocarditis.¹⁶

Although patients affected by PF can be young and healthy, several risk factors for PF have been identified^2,6,16: asplenia, an immunocompromised state, systemic corticosteroid use, cirrhosis, and alcoholism. Asplenic patients have been shown to be particularly susceptible to systemic Capnocytophaga infection; when bitten by a dog, they should be treated with prophylactic antibiotics to cover Capnocytophaga.¹⁷ Immunocompetent patients rarely develop severe infection with Capnocytophaga.^16,18,19 The complement system in particular is critically important in defending against C canimorsus.²⁰

The underlying pathophysiology of acute infectious PF is multifactorial, encompassing increased expression of procoagulant tissue factor by monocytes and endothelial cells in the presence of bacterial pathogens. Dysfunction of protein C, an anticoagulant component of the coagulation cascade, often is cited as a crucial derangement leading to the development of a prothrombotic state in acute infectious PF.²¹ Serum protein S and antithrombin deficiency also can play a role.²² Specific in vitro examination of C canimorsus has revealed a protease that catalyzes N-terminal cleavage of procoagulant factor X, resulting in loss of function.¹⁵

Retiform purpura is a hallmark feature of PF, often beginning as nonblanching erythema with localized edema and petechiae before evolving into the characteristic stellate lesions with hemorrhagic bullae and subsequent necrosis.²³ Pathologic examination reveals microthrombi involving arterioles and smaller vessels.²⁴ There typically is laboratory evidence of DIC in PF, including elevated prothrombin time and partial thromboplastin time, thrombocytopenia, elevated D-dimer, and a decreased fibrinogen level.^6,23

Capnocytophaga bacteria are challenging to grow on standard culture media. Optimal media for growth include 5% sheep’s blood and chocolate agar.¹⁶ Polymerase chain reaction can identify Capnocytophaga; in cases in which blood culture does not produce growth, 16S ribosomal RNA gene sequencing of tissue from skin biopsy has identified the pathogen.²⁵

Some Capnocytophaga isolates have been shown to produce beta-lactamase; individual strains can be resistant to penicillins, cephalosporins, and imipenem.²⁶ Factors associated with an increased risk for death include decreased leukocyte and platelet counts and an increased level of arterial lactate.²⁷

Empiric antibiotic therapy for Capnocytophaga sepsis should include a beta-lactam and beta-lactamase inhibitor, such as piperacillin-tazobactam. Management of DIC can include therapeutic heparin or low-molecular-weight heparin and prophylactic platelet transfusion to maintain a pre-established value.^28-30 Debridement should be conservative; it is important to wait for definite delineation between viable and necrotic tissue,³¹ which might take several months.³² Human skin allografts, in addition to artificial skin, are utilized as supplemental therapy for more rapid wound closure after removal of necrotic tissue.^33,34 Hyperoxygenated fatty acids have been noted to aid in more rapid wound healing in infants with PF.³⁵

Fresh frozen plasma is one method to replace missing factors, but it contains little protein C.³⁶ Outcomes with recombinant human activated protein C (drotrecogin alfa) are mixed, and studies have shown no benefit in reducing the risk for death.^37,38 Protein C concentrate has shown therapeutic benefit in some case reports and small retrospective studies.⁴ In one case report, protein C concentrate and heparin were utilized in combination with antithrombin III.²¹

Hyperbaric O₂ might be of benefit when initiated within 5 days after onset of PF. However, hyperbaric O₂ does carry risk; O₂ toxicity, barotrauma, and barriers to timely resuscitation when the patient is inside the pressurized chamber can occur.²

There is a single report of successful use of the vasodilator iloprost for meningococcal PF without need for surgical intervention; the team also utilized topical nitroglycerin patches on the fingers to avoid digital amputation.³⁹ Epoprostenol, tissue plasminogen activator, and antithrombin have been utilized in cases of extensive PF. Fibrinolytic therapy might have some utility, but only in a setting of malignancy-associated DIC.⁴⁰

Treatment of acute infectious PF lacks a high level of evidence. Options include replacement of anticoagulant factors, anticoagulant therapy, hyperbaric O₂, topical and systemic vasodilators, and, in the setting of underlying cancer, fibrinolytics. Even with therapy, prognosis is guarded.

Purpura fulminans (PF) is an acute, life-threatening condition characterized by intravascular thrombosis and hemorrhagic necrosis of the skin. It classically presents as retiform purpura with branched or angular purpuric lesions. Purpura fulminans often occurs in the setting of disseminated intravascular coagulation, secondary to sepsis, trauma, malignancy, autoimmune disease, and congenital or acquired protein C or S deficiency, among other abnormalities.¹ Rapid identification and treatment of the underlying cause are mainstays of management. We report a case of PF secondary to Vibrio vulnificus infection and highlight the importance of timely consideration of this etiologic agent due to the high mortality rate and specific treatment required.

A 58-year-old man with liver cirrhosis and hepatitis B virus presented with pain, swelling, and localized erythema affecting both legs as well as a fever. He reported vomiting blood and an episode of bloody diarrhea over the preceding 24 hours. He denied exposure to sick contacts or a history of autoimmune disease. At initial presentation to the emergency department, physical examination revealed few scattered, sharply demarcated, erythematous to violaceous patches that rapidly progressed overnight to hemorrhagic bullae and widespread retiform purpuric patches on both legs (Figure 1). As the patient’s skin condition worsened, he had a blood pressure of 80/50 mm Hg and a pulse rate of 110/min. Serum analysis was notable for mild leukocytosis (10.74×10⁹/L [reference range, 4.8–10.8×10⁹/L), thrombocytopenia (39×10⁹/L [reference range, 150–450×10⁹/L]), and decreased C3 (25 mg/dL [reference range, 81–157 mg/dL]) and C4 (8 mg/dL [reference range, 13–39 mg/dL]). Laboratory findings also were remarkable for prothrombin time (23.3 seconds [reference range, 8.8–12.3 seconds]), partial thromboplastin time (52.5 seconds [reference range, 23.6–35.8 seconds]), and international normalized ratio (2.01 [reference range, 0.8–1.13]). Aspartate transaminase (237 U/L [reference range, 11–39 U/L]) and alanine transaminase (80 U/L [reference range, 11–35 U/L]) were elevated, while antineutrophil cytoplasmic antibodies, serum immunoglobulin, and cryoglobulins were unremarkable. Punch biopsies of the left thigh were performed, and histopathology revealed small vessel thrombosis and ischemic changes consistent with PF (Figure 2). Vancomycin, clindamycin, cefepime injection, and piperacillin-tazobactam were administered intravenously for empiric broad-spectrum sepsis coverage. Within hours, the patient experienced refractory septic shock with disseminated intravascular coagulation and died from pulmonary embolism and subsequent cardiac arrest. Tissue and blood cultures grew V vulnificus.

Vibrio vulnificus is a gram-negative bacillus and a rare cause of primary septicemia following consumption of shellfish, especially oysters. Wounds exposed to saltwater or brackish water contaminated with the microorganism can produce soft-tissue infections. Individuals with chronic liver disease are at greater risk for V vulnificus infection.² The clinical presentation of V vulnificus includes early cellulitislike patches, late purpura with hemorrhagic bullae, and rapidly progressing shock.³

Mortality rates from V vulnificus infection are high.⁴ Therefore, it is recommended to presumptively diagnose V vulnificus septicemia in any individual at risk for infection who presents with the characteristic history in the setting of hypotension, fever, or septic shock. It is crucial for providers to be aware that broad-spectrum antibiotics commonly used for sepsis are inadequate for the treatment of V vulnificus. Immediate treatment with tetracycline (minocycline or doxycycline) and a third-generation cephalosporin (cefotaxime or ceftriaxone injection) or in combination with ciprofloxacin has been proven effective.^4,5

Vibrio vulnificus rarely is described in the literature as inducing PF. In one previously reported case, the patient was otherwise healthy and managed to recover following antibiotic therapy and wound debridement,⁶ whereas in another case the patient had undiagnosed liver cirrhosis and died from the infection.^6,7 In the latter case, the patient presented to the emergency department in a coma. Our patient did not have the clinical signs of sepsis upon initial presentation to the emergency department. It is possible the infection rapidly progressed because of his underlying liver disease. Genotyping analysis of V vulnificus has shown that strains with low pathogenicity can cause primary septicemia in humans.⁷

Our case reinforces the need to quickly recognize V vulnificus as a rare underlying cause of PF and administer the appropriate treatment.

Serum analysis was notable for mild leukocytosis (10.74×10⁹/L [reference range, 4.8–10.8×10⁹/L), thrombocytopenia (39×10⁹/L [reference range, 150–450×10⁹/L]), and decreased C3 (25 mg/dL [reference range, 81–157 mg/dL]) and C4 (8 mg/dL [reference range, 13–39 mg/dL]). Laboratory findings also were remarkable for prothrombin time (23.3 seconds [reference range, 8.8–12.3 seconds]), partial thromboplastin time (52.5 seconds [reference range, 23.6–35.8 seconds]), and international normalized ratio (2.01 [reference range, 0.8–1.13]). Aspartate transaminase (237 U/L [reference range, 11–39 U/L]) and alanine transaminase (80 U/L [reference range, 11–35 U/L]) were elevated, while antineutrophil cytoplasmic antibodies, serum immunoglobulin, and cryoglobulins were unremarkable. Punch biopsies of the left thigh were performed, and histopathology revealed small vessel thrombosis and ischemic changes consistent with PF (Figure 2). Vancomycin, clindamycin, cefepime injection, and piperacillin-tazobactam were administered intravenously for empiric broad-spectrum sepsis coverage. Within hours, the patient experienced refractory septic shock with disseminated intravascular coagulation and died from pulmonary embolism and subsequent cardiac arrest. Tissue and blood cultures grew V vulnificus.

Vibrio vulnificus is a gram-negative bacillus and a rare cause of primary septicemia following consumption of shellfish, especially oysters. Wounds exposed to saltwater or brackish water contaminated with the microorganism can produce soft-tissue infections. Individuals with chronic liver disease are at greater risk for V vulnificus infection.² The clinical presentation of V vulnificus includes early cellulitislike patches, late purpura with hemorrhagic bullae, and rapidly progressing shock.³

Mortality rates from V vulnificus infection are high.⁴ Therefore, it is recommended to presumptively diagnose V vulnificus septicemia in any individual at risk for infection who presents with the characteristic history in the setting of hypotension, fever, or septic shock. It is crucial for providers to be aware that broad-spectrum antibiotics commonly used for sepsis are inadequate for the treatment of V vulnificus. Immediate treatment with tetracycline (minocycline or doxycycline) and a third-generation cephalosporin (cefotaxime or ceftriaxone injection) or in combination with ciprofloxacin has been proven effective.^4,5

Vibrio vulnificus rarely is described in the literature as inducing PF. In one previously reported case, the patient was otherwise healthy and managed to recover following antibiotic therapy and wound debridement,⁶ whereas in another case the patient had undiagnosed liver cirrhosis and died from the infection.^6,7 In the latter case, the patient presented to the emergency department in a coma. Our patient did not have the clinical signs of sepsis upon initial presentation to the emergency department. It is possible the infection rapidly progressed because of his underlying liver disease. Genotyping analysis of V vulnificus has shown that strains with low pathogenicity can cause primary septicemia in humans.⁷

Our case reinforces the need to quickly recognize V vulnificus as a rare underlying cause of PF and administer the appropriate treatment.

To the Editor:

Purpura fulminans (PF) is an acute, life-threatening condition characterized by intravascular thrombosis and hemorrhagic necrosis of the skin. It classically presents as retiform purpura with branched or angular purpuric lesions. Purpura fulminans often occurs in the setting of disseminated intravascular coagulation, secondary to sepsis, trauma, malignancy, autoimmune disease, and congenital or acquired protein C or S deficiency, among other abnormalities.¹ Rapid identification and treatment of the underlying cause are mainstays of management. We report a case of PF secondary to Vibrio vulnificus infection and highlight the importance of timely consideration of this etiologic agent due to the high mortality rate and specific treatment required.

A 58-year-old man with liver cirrhosis and hepatitis B virus presented with pain, swelling, and localized erythema affecting both legs as well as a fever. He reported vomiting blood and an episode of bloody diarrhea over the preceding 24 hours. He denied exposure to sick contacts or a history of autoimmune disease. At initial presentation to the emergency department, physical examination revealed few scattered, sharply demarcated, erythematous to violaceous patches that rapidly progressed overnight to hemorrhagic bullae and widespread retiform purpuric patches on both legs (Figure 1). As the patient’s skin condition worsened, he had a blood pressure of 80/50 mm Hg and a pulse rate of 110/min. Serum analysis was notable for mild leukocytosis (10.74×10⁹/L [reference range, 4.8–10.8×10⁹/L), thrombocytopenia (39×10⁹/L [reference range, 150–450×10⁹/L]), and decreased C3 (25 mg/dL [reference range, 81–157 mg/dL]) and C4 (8 mg/dL [reference range, 13–39 mg/dL]).

Patients with immune-mediated inflammatory diseases (IMIDs), such as inflammatory bowel disease and rheumatic conditions, have a reduced serologic response to a 2-dose vaccination regimen with mRNA COVID-19 vaccines, according to the findings of a meta-analysis.

“These results suggest that IMID patients receiving mRNA vaccines should complete the vaccine series without delay and support the strategy of providing a third dose of the vaccine,” wrote study authors Atsushi Sakuraba, MD, of the University of Chicago Medicine, and colleagues in Gastroenterology.

During the COVID-19 pandemic, concerns were raised about the susceptibility of patients with pre-existing conditions to infection with the novel coronavirus, the authors noted. Likewise, ongoing concerns have centered on the risk of worse COVID-19–related outcomes among patients with IMIDs who are treated with immunosuppressive agents.

Since the onset of the pandemic, several registries have been established to gauge the incidence and prognosis of COVID-19 in patients with IMID, including the Surveillance Epidemiology of Coronavirus Under Research Exclusion (SECURE)–Inflammatory Bowel Disease (IBD) registry and the COVID-19 Global Rheumatology Alliance 75 (C19-GRA), which includes patients with rheumatic diseases.

Authorization of COVID-19 mRNA vaccines provided hope that the COVID-19 pandemic could soon come to an end given the overwhelming safety and efficacy data supporting the use of these vaccines for preventing hospitalization and death. Despite these data, little is known regarding the efficacy of mRNA COVID-19 vaccines in patients with IMIDs and/or patients treated with immunosuppressive therapies, as these patients were excluded from the regulatory vaccine studies.

The study by Dr. Sakuraba and colleagues was a meta-analysis of 25 observational studies that reported serologic response rates to COVID-19 vaccination in a pooled cohort of 5,360 patients with IMIDs. Data regarding the reference population, medications, vaccination, and proportion of patients who achieved a serologic response were extracted from the observational studies and included in the meta-analysis.

In the analyzed studies, serologic response was evaluated separately after one or two vaccine doses. The researchers also examined the post-vaccine serologic response rate in patients with IMIDs versus controls without IMIDs.

A total of 23 studies used the BNT162b2 or mRNA-1273 vaccines, while 3 studies reported that 50% to 75.9% of patients received the AZD1222 vaccine. Some studies also included patients who received other COVID-19 vaccines, including CoronaVac, BBV152, and Ad26.COV2.S.

While 6 studies assessed serologic response to COVID-19 after just 1 dose, 20 studies assessed the post-vaccination serologic response following 2 doses. In most cases, researchers evaluated serologic response at 2 to 3 weeks after the first dose. After the second vaccine dose, most studies examined serologic response at 1 to 3 weeks.

The serologic response after 1 dose of the mRNA vaccines was 73.2% (95% CI 65.7-79.5). In a multivariate meta-regression analysis, the researchers found that a significantly greater proportion of patients with IMIDs who took anti-tumor necrosis factor (anti-TNF) therapies had a lower serologic response rate (coefficient, –2.60; 95% CI –4.49 to –0.72; P =.0069). The investigators indicated this “likely contributed to the difference in serologic response rates and overall heterogeneity.”

Studies with patients with IBD reported a lower serologic response rate compared with studies that included patients with rheumatoid arthritis (49.2% vs. 65.0%, respectively), which the investigators explained was likely reflective of the increased use of anti-TNF agents in patients with IBD.

After 2 doses of the mRNA vaccines, the pooled serologic response was 83.4% (95% CI, 76.8%-88.4%). Multivariate meta-regression found that a significantly greater proportion of patients who took anti-CD20 treatments had a lower serologic response (coefficient, -6.08; 95% CI -9.40 to -2.76; P <.001). The investigators found that older age was significantly associated with lower serologic response after 2 doses (coefficient, -0.044; 95% CI -0.083 to -0.0050; P =.027).

For the non-mRNA COVID-19 vaccines, the rates of serologic response after 2 doses were 93.5% with AZD1222, 22.9% with CoronaVac, and 55.6% with BBV152.

Compared with controls without IMIDs, those with IMIDs were significantly less likely to achieve a serologic response following 2 mRNA vaccine doses (odds ratio, 0.086; 95% CI 0.036-0.206; P <.001). The investigators noted that there were not enough studies to examine and compare serologic response rates to adenoviral or inactivated vaccines between patients and controls.

In terms of limitations, the researchers wrote that additional studies examining humoral and cellular immunity to COVID-19 vaccines are needed to determine vaccine efficacy and durability in patients with IMIDs. Additionally, there is a need for studies with larger patient populations to determine serologic response to COVID-19 vaccines in the broader IMID population.

The researchers reported no funding for the study and no relevant conflicts of interest with the pharmaceutical industry.

A 64 year-old man with type 2 diabetes complains of recurrent flushing for the past 6 months. He has had no other symptoms. His only abnormalities on physical exam are a blood pressure of 160/100 and mild peripheral edema.

His current medications include: Famotidine 20 mg b.i.d., Pseudoephedrine/guaifenesin SR b.i.d., Metformin 1,000 mg twice a day, Nifedipine 60 mg XL once a day, and Atorvastatin 20 mg once a day.

His laboratory work up includes: blood urea nitrogen: 20, creatinine: 1.3, sodium: 140, Chloride: 104, potassium: 3.9, glucose: 205, white blood cell count: 6,000, hematocrit: 41, 24-hour urine 5-hydroxyindoleacetic acid (5HIAA) test: 12 mg/day (normal 2-8 mg/day), free catecholamines: 80 mg/24 hours (normal less than 100 mg/24 hours).
 

What is the most likely diagnosis?

A. Drug effect

B. Pheochromocytoma

C. Carcinoid syndrome

D. Mastocytosis

E. Medullary thyroid cancer

The most likely diagnosis is a drug effect. His flushing is likely caused by nifedipine.

Flushing is one of the most common side effects of this drug.¹ This patient had lab testing done for carcinoid (urine 5HIAA), presumably because he had flushing. This lab test result was a false positive, likely because of guaifenesin ingestion, which can cause false-positive 5HIAA results.²

Carcinoid syndrome is very rare (estimates from less than 1 patient/100,000), and the vast majority of patients who have it present with metastatic disease at presentation. Drug side effects are common, and usually are much more likely than rare diseases.
 

Four principles for assisting with making a diagnosis

This case points out the following four principles that I will touch on to help us make diagnoses in challenging cases.

1. Trigger symptoms: These are symptoms that make us think of a rare disease. In this case, the symptom is flushing, which may make you think of carcinoid syndrome.

Another good example of a trigger symptom is night sweats, where you may think of tuberculosis or lymphoma. These symptoms almost always have a much more common and likely cause, which in this case is a common drug side effect.

Trigger symptoms are great to pay attention to, but do not jump to working up the rare diagnosis without more evidence that it is a plausible diagnosis. Working up rare diseases without a reasonable pretest probability will lead to significant false-positive results.

2. Distinguishing features: These are findings, or combinations of findings, that make rarer diseases more likely. For example, flushing, although seen in many patients with carcinoid syndrome, is much more commonly caused by rosacea, medications, or estrogen/testosterone deficiency.

If a patient presents with flushing plus diarrhea, carcinoid syndrome becomes more likely in differentials. An example of a specific distinguishing feature is transient visual obstructions in patients with idiopathic intracranial hypertension (IIH or pseudotumor cerebri).

Sudden transient visual loss is not a symptom we see often, but headaches and obesity are problems we see every day. A patient with headaches and obesity is very likely to have IIH if they have transient visual obstructions along with headaches and obesity.

3. Intentional physical exams: Do the physical exam focusing on what findings will change your diagnostic probabilities. For example, in this case, if you are considering carcinoid, do a careful abdominal exam, with close attention to the liver, as 75% of patients with carcinoid syndrome have liver metastases.

If you are thinking about IIH, a fundoscopic exam is mandatory, as papilledema is a key feature of this diagnosis.

Read about the rare diagnosis you are considering, this will help with targeting your exam.

4. Remember the unusual presentation of a common disease is more common than the common presentation of a rare disease: Good examples of this are sleep apnea and gastroesophageal reflux disease causing night sweats more commonly than finding lymphomas or active tuberculosis (in the United States) as the cause.³

Pearl: Trigger symptoms help us think of rare diseases, but distinguishing features are most helpful in including or excluding the diagnosis.

His current medications include: Famotidine 20 mg b.i.d., Pseudoephedrine/guaifenesin SR b.i.d., Metformin 1,000 mg twice a day, Nifedipine 60 mg XL once a day, and Atorvastatin 20 mg once a day.

His laboratory work up includes: blood urea nitrogen: 20, creatinine: 1.3, sodium: 140, Chloride: 104, potassium: 3.9, glucose: 205, white blood cell count: 6,000, hematocrit: 41, 24-hour urine 5-hydroxyindoleacetic acid (5HIAA) test: 12 mg/day (normal 2-8 mg/day), free catecholamines: 80 mg/24 hours (normal less than 100 mg/24 hours).
 

What is the most likely diagnosis?

A. Drug effect

B. Pheochromocytoma

C. Carcinoid syndrome

D. Mastocytosis

E. Medullary thyroid cancer

The most likely diagnosis is a drug effect. His flushing is likely caused by nifedipine.

Flushing is one of the most common side effects of this drug.¹ This patient had lab testing done for carcinoid (urine 5HIAA), presumably because he had flushing. This lab test result was a false positive, likely because of guaifenesin ingestion, which can cause false-positive 5HIAA results.²

Carcinoid syndrome is very rare (estimates from less than 1 patient/100,000), and the vast majority of patients who have it present with metastatic disease at presentation. Drug side effects are common, and usually are much more likely than rare diseases.
 

Four principles for assisting with making a diagnosis

This case points out the following four principles that I will touch on to help us make diagnoses in challenging cases.

1. Trigger symptoms: These are symptoms that make us think of a rare disease. In this case, the symptom is flushing, which may make you think of carcinoid syndrome.

Another good example of a trigger symptom is night sweats, where you may think of tuberculosis or lymphoma. These symptoms almost always have a much more common and likely cause, which in this case is a common drug side effect.

Trigger symptoms are great to pay attention to, but do not jump to working up the rare diagnosis without more evidence that it is a plausible diagnosis. Working up rare diseases without a reasonable pretest probability will lead to significant false-positive results.

2. Distinguishing features: These are findings, or combinations of findings, that make rarer diseases more likely. For example, flushing, although seen in many patients with carcinoid syndrome, is much more commonly caused by rosacea, medications, or estrogen/testosterone deficiency.

If a patient presents with flushing plus diarrhea, carcinoid syndrome becomes more likely in differentials. An example of a specific distinguishing feature is transient visual obstructions in patients with idiopathic intracranial hypertension (IIH or pseudotumor cerebri).

Sudden transient visual loss is not a symptom we see often, but headaches and obesity are problems we see every day. A patient with headaches and obesity is very likely to have IIH if they have transient visual obstructions along with headaches and obesity.

3. Intentional physical exams: Do the physical exam focusing on what findings will change your diagnostic probabilities. For example, in this case, if you are considering carcinoid, do a careful abdominal exam, with close attention to the liver, as 75% of patients with carcinoid syndrome have liver metastases.

If you are thinking about IIH, a fundoscopic exam is mandatory, as papilledema is a key feature of this diagnosis.

Read about the rare diagnosis you are considering, this will help with targeting your exam.

4. Remember the unusual presentation of a common disease is more common than the common presentation of a rare disease: Good examples of this are sleep apnea and gastroesophageal reflux disease causing night sweats more commonly than finding lymphomas or active tuberculosis (in the United States) as the cause.³

Pearl: Trigger symptoms help us think of rare diseases, but distinguishing features are most helpful in including or excluding the diagnosis.

How much did you get per tooth from the Tooth Fairy? How much do your children or grandchildren receive each time they lose a baby tooth? In my family the Tooth Fairy seems to be more than keeping with inflation. Has she ever been caught in the act of swapping cash for enamel in your home? Has she every slipped up one night but managed to resurrect her credibility the following night by doubling the reward? And, by the way, what does the Tooth Fairy do with all those teeth, and who’s funding her nocturnal switcheroos?

A recent study from the Center for Genomic Medicine at the Massachusetts General Hospital in Boston may provide an answer to at least one of those questions. It turns out some researchers have been collecting baby teeth in hopes of assessing prenatal and perinatal stress in infants.

Not surprisingly, teeth are like trees, preserving a history of the environment in their growth rings. The Boston researchers hypothesized that the thickness of one particular growth line referred to as the neonatal line (NNL) might reflect prenatal and immediate postnatal environmental stress. Using data and naturally shed teeth collected in an English longitudinal study, the authors discovered that the teeth of children whose mothers had a long history of severe depression or other psychiatric problems and children of mothers who at 32 weeks’ gestation experienced anxiety and/or depression were more likely to have thicker NNLs. On the other hand, the teeth of children whose mothers had received “significant social support” in the immediate postnatal period exhibited thinner NNLs.

Based on anecdotal observations, I think most of us already suspected that the children whose mothers had significant psychiatric illness began life with a challenge, but it is nice to know that we may now have a tool to document one small bit of evidence of the structural damage that occurred during this period of stress. Of course, the prior owners of these baby teeth won’t benefit from the findings in this study; however, the evidence that social support during the critical perinatal period can ameliorate the damage might stimulate more robust prenatal programs for mother and infants at risk in the future.

It will be interesting to see if this investigative tool becomes more widely used to determine the degree to which a variety of potential perinatal stressors are manifesting themselves in structural change in newborns. For example, collecting baby teeth from neonatal ICU graduates may answer some questions about how certain environmental conditions such as sound, vibration, bright light, and temperature may result in long-term damage to the infants. Most of us suspect that skin-to-skin contact with mother and kangaroo care are beneficial. A study that includes a survey of NNLs might go a long way toward supporting our suspicions.

I can even imagine that a deep retrospective study of NNLs in baby teeth collected over the last 100 years might demonstrate the effect of phenomena such as wars, natural disasters, forced migration, and pandemics, to name a few.

It may be time to put out a nationwide call to all Tooth Fairies both active and retired to dig deep in their top bureau drawers. Those little bits of long-forgotten enamel may hold the answers to a plethora of unanswered questions about those critical months surrounding the birth of a child.

Most cases of new daily persistent headache (NDPH) are moderate to severe and many feature characteristics often associated with migraine, according to a new retrospective chart review.

“Future prospective studies are needed to better understand this disabling disorder,” wrote Randolph W. Evans, MD, of Baylor College of Medicine of Houston, and Dana P. Turner, PhD, of Massachusetts General Hospital and Harvard Medical School in Boston. Their study was published Oct. 28 in Headache.

To categorize the infrequently reported clinical features of NDPH, the researchers launched a retrospective study of patients who were provisionally diagnosed with NDPH by Dr. Evans at an outpatient clinic in Houston from Sept. 1, 2011, to Feb. 28, 2020. Of the 328 patients whose diagnosis ultimately matched the ICHD-3 criteria, the average age at onset was 40.3 years (range 12-87 years). Approximately 70% were White, and nearly 66% were women. Two hundred and sixty were diagnosed with the migraine phenotype and 68 were diagnosed with the tension-type phenotype.
 

Key features

The median duration of NDPH at the time of the initial consult with Dr. Evans was 0.7 years, and it was 1.9 years at the time of the last visit. Almost 33% of patients with the migraine phenotype had a history of episodic migraine compared with 16.2% with the tension-type phenotype. Headaches were side-locked unilateral in 8.5% (n = 28) of all patients, and 3.6% (n = 12) had a thunderclap onset.

The most common clinical features across all patients included noise sensitivity (72.1%), light sensitivity (71%), moderate pain at the time of initial consult (57.9%), pressure pain (54.9%), and throbbing pain (50.9%). Nausea was reported in 157 patients and vomiting was reported in 48 patients, all of whom were in the migraine phenotype group. Thunderclap onset was far more prevalent in the migraine phenotype group (11 patients) compared with the tension-type phenotype group (1 patient), as was vertigo (19 patients compared with 1) and visual aura (21 compared with 0).

The top precipitating factors across all patients included stressful life events (20.4%), an antecedent upper respiratory infection or flu-like illness (10.1%), and antecedent extracranial surgery (1.5%). Exacerbating or aggravating factors were far more prevalent in the migraine phenotype group compared with the tension-type phenotype group, with stress (14.6% vs. 5.9%), bright or flashing light (10.4% vs. 1.5%), loud noise (8.5% vs. 0%), and lack of sleep (6.5% vs. 4.4%) leading the way.

The months with the most onsets were June (8.5%), January (7.6%), and February (7.6%); there was no clear seasonal or cyclical variation. The most common prognostic type across all patients was persisting (refractory) at 93%, followed by remitting (self-limiting) at 4.3% and relapsing-remitting at 2.7%.
 

Unlocking a medical mystery

“This is the largest case review study ever published on NDPH, especially because most people think it’s a fairly rare disorder when it’s actually not,” Herbert G. Markley, MD, of the New England Regional Headache Center in Worcester, Mass., said in an interview.

“The thing people need to understand is that they may have a lot of these patients in their practice and not realize it,” he added. “They keep trying one medication after another, and the patients are giving up, and the doctors are giving up. It’s terrible. We don’t know what causes it, and we don’t know how to treat it. It’s one of the biggest mysteries left in medical science.”

“My idea about this condition, and this is shared by others, is that NDPH is not a diagnosis that describes a cohesive group of patients but rather a group of people who share certain features,” Morris Levin, MD, director of the Headache Center at the University of California, San Francisco, said in an interview. “And they would be better served if this diagnosis was split into different categories.”

While praising Dr. Evans and Dr. Turner for their categorization and classification work, Dr. Levin asked, “Let’s say you diagnose someone with NDPH; does that in any way help you with management of this person? The answer is no. Some might say, ‘If you put the patients in the migraine phenotype group, then you can use migraine treatments.’ My point would be: then call it migraine.

“I believe another way to approach NDPH might be to create subcategories of migraine and tension-type headaches,” he added. “A migraine that is either intermittent or nonexistent suddenly becomes daily. That could be a subcategory; rather than being called NDPH, call it ‘new persistent chronic migraine.’ Or ‘new persistent chronic tension-type headache.’ Perhaps that would serve us better in terms of grasping the underlying mechanisms and the best treatment for these patients.”

Along the same lines, Dr. Markley echoed Dr. Evans’ call for more prospective studies and more research on possible medication, hoping to fuel further understanding of this debilitating disorder.

“I think this will be a landmark study for people to look back on,” he said, “especially for anyone going into the headache specialty who has never heard of this type of headache and keeps wondering why they can’t help certain patients, no matter how many medications they try.”

The authors acknowledged their study’s limitations, including its single-center nature and the data abstraction process being performed by just one person. They added, however, that Dr. Evans is a “very experienced researcher with more than 30 years of experience in headache medicine who was abstracting his own patients, data that were very familiar to him.”

Dr. Evans and Dr. Turner declared no potential conflicts of interest.

The oral sphingosine-1-phosphate receptor modulator ozanimod is significantly more effective than placebo for treating patients with moderate to severe ulcerative colitis, regardless of prior biologic exposure, based on results of the phase 3 True North trial.

Although improvements were seen across all patients, those who had previously used biologics took slightly longer to respond to treatment, which suggests that any initial improvements with ozanimod warrant continuation of therapy to achieve full effect, reported to lead author Bruce E. Sands, MD, of Icahn School of Medicine at Mount Sinai, New York, and colleagues.

“[Ulcerative colitis] patients previously treated with a biologic agent may be less likely to respond to another advanced treatment,” Dr. Sands said during a presentation at the annual meeting of the American College of Gastroenterology.

Dr. Sands and colleagues evaluated this possibility in the True North trial, which previously demonstrated superior efficacy and safety of ozanimod over placebo through 1 year.

The present dataset included a double-blinded cohort of 639 patients (cohort 1), among whom 213 took placebo and 426 took ozanimod, and an open-label cohort of 353 patients who took ozanimod (cohort 2). Outcomes included clinical remission, clinical response, endoscopic improvement, and mucosal healing.

During induction (through week 10), biologic-naive patients in both cohorts generally responded better to ozanimod than those who had received at least one prior biologic. Patients who had received two or more biologics showed less improvement than those who had received only one prior biologic.

For example, in cohort 1, 53% of biologic-naive patients in the ozanimod group achieved a clinical response, compared with 50% of patients who had received one prior biologic, and just 27.2% of patients who had received two or more biologics.

With maintenance therapy, however, these differences faded. Among participants continuing ozanimod through week 52, 60.7% of biologic-naive patients achieved a clinical response, compared with 60.5% of those who had taken one prior biologic, and 55.3% of patients who had taken two or more prior biologics.

“Ozanimod treatment for up to 52 weeks in patients with moderate to severe ulcerative colitis improved clinical symptoms, mucosal ulcerations, and reduced cellular inflammation in both biologic-exposed and biologic-naive patients,” Dr. Sands concluded. “Greater efficacy was observed in biologic-naive patients, followed by patients with prior exposure to one biologic, at induction; however, all groups had benefits at end of maintenance. Patients with prior biologic use may require additional time to respond to treatment.”

Bradley Morganstern, MD, codirector of the IBD Center at Stony Brook (N.Y.) Medicine, called the study “a really important analysis” that addresses a common clinical decision.

“We often see a lower response rate among patients previously on biologics, but we have very limited data to guide us on how to choose a second-line agent,” Dr. Morganstern said during an interview.

He said the current findings encourage use of ozanimod for patients who didn’t respond to other biologics.

“The takeaway is that just because someone didn’t respond to a biologic in the past doesn’t mean they won’t respond to this,” Dr. Morganstern said. “They actually have a very good chance of responding – similar to the rest of the population that was never on medication.”

He went on to explain that exact treatment sequencing remains unclear, although ozanimod is a strong candidate in the second line.

“We can’t 100% say where it [ozanimod] fits in,” Dr. Morganstern said, “but we should certainly place it high up in the algorithm for patients who have failed a biologic. This should strongly be considered as a second-line agent.”

Dr. Morganstern said that he looks forward to long-term findings from True North beyond 1 year, “in terms of maintaining response,” and additional safety data.

The study was funded supported by Bristol-Myers Squibb. The investigators disclosed additional affiliations with AstraZeneca, AbbVie, Amgen, and others. Dr. Morganstern has previously spoken for Bristol-Myers Squibb.

Although improvements were seen across all patients, those who had previously used biologics took slightly longer to respond to treatment, which suggests that any initial improvements with ozanimod warrant continuation of therapy to achieve full effect, reported to lead author Bruce E. Sands, MD, of Icahn School of Medicine at Mount Sinai, New York, and colleagues.

“[Ulcerative colitis] patients previously treated with a biologic agent may be less likely to respond to another advanced treatment,” Dr. Sands said during a presentation at the annual meeting of the American College of Gastroenterology.

Dr. Sands and colleagues evaluated this possibility in the True North trial, which previously demonstrated superior efficacy and safety of ozanimod over placebo through 1 year.

The present dataset included a double-blinded cohort of 639 patients (cohort 1), among whom 213 took placebo and 426 took ozanimod, and an open-label cohort of 353 patients who took ozanimod (cohort 2). Outcomes included clinical remission, clinical response, endoscopic improvement, and mucosal healing.

During induction (through week 10), biologic-naive patients in both cohorts generally responded better to ozanimod than those who had received at least one prior biologic. Patients who had received two or more biologics showed less improvement than those who had received only one prior biologic.

For example, in cohort 1, 53% of biologic-naive patients in the ozanimod group achieved a clinical response, compared with 50% of patients who had received one prior biologic, and just 27.2% of patients who had received two or more biologics.

With maintenance therapy, however, these differences faded. Among participants continuing ozanimod through week 52, 60.7% of biologic-naive patients achieved a clinical response, compared with 60.5% of those who had taken one prior biologic, and 55.3% of patients who had taken two or more prior biologics.

“Ozanimod treatment for up to 52 weeks in patients with moderate to severe ulcerative colitis improved clinical symptoms, mucosal ulcerations, and reduced cellular inflammation in both biologic-exposed and biologic-naive patients,” Dr. Sands concluded. “Greater efficacy was observed in biologic-naive patients, followed by patients with prior exposure to one biologic, at induction; however, all groups had benefits at end of maintenance. Patients with prior biologic use may require additional time to respond to treatment.”

For years, it has been strongly suspected that malignant melanoma is underreported in the United States. I have audited my melanoma cases (biopsies and excisions sent to me) and discovered that of the 240 cases confirmed over the past 5 years, only 41 were reported to the Ohio state health department and are in that database. That amounts to 199 unreported cases – nearly 83% of the total.

This raises the question as to who is responsible for reporting these cases. Dermatology is unique in that our pathology specimens are not routinely passed through a hospital pathology laboratory. The big difference in reporting is that hospital labs have trained data registrars to report all reportable cancers to state health departments. Therefore, in my case, only patients sent to a hospital-based surgeon for sentinel node biopsies or exceptionally large excisions get reported. When I have spoken about this to my dermatology lab and biopsying physicians, the discussion rapidly turns into a finger pointing game of who is responsible. No one, except perhaps the dermatologist who did the biopsy, has all the data.

Unfortunately, these cases are tedious and time consuming to report. Despite state laws requiring reporting, even with penalties for nonreporters, many small dermatology practices do not report these cases and expect their dermatopathology labs to do so, but the labs expect the biopsying dermatologist to report the cases. This is a classic case of an unfunded mandate since small dermatology practices do not have the time or resources for reporting.

I have worked with the Ohio Department of Health to remove any unnecessary data fields and they have managed to reduce the reporting fields (to 59!). This is the minimum amount required to be included in the National Cancer Institute’s SEER (Surveillance, Epidemiology, and End Results) database. Many of these fields are not applicable to thin melanomas and after reviewing the 1-hour online training course, each patient can be entered (once the necessary data are collected) in about 15 minutes. This is still a formidable task for small offices, which cannot be blamed for ducking and hoping someone else reports.

While there is controversy regarding the relevance of thin melanomas to overall survival, more accurate reporting can only bolster either argument.
 

A solution to underreporting

I believe we have developed a unique solution to this conundrum. Our office is partnering with the local melanoma support group (Melanoma Know More) to train volunteers to help with the data collection and reporting of these thin melanomas. We have also discovered that the local community college has students who are majoring in pathology data registry reporting and are happy to gain a little experience before graduating.

We eventually hope to become a clearinghouse for the entire state of Ohio. The state health department has agreed not to apply punitive measures to physicians who are new reporters. It is our plan to obtain melanoma pathology reports, run these past the state database, identify unreported cases, and obtain further data as needed from the biopsying physicians, and then complete the reporting.

I think dermatologic oncologists in every state should view this as an opportunity for a significant quality improvement project, and as a terrific service to the general dermatology community.

The ramifications of more comprehensive reporting of melanomas are great. I would expect more attention to the disease by researchers, and much more clout with state and national legislators. Think about increased funding for melanoma research, allowing sunscreen use for school children, sunshades for playgrounds, and more responsible tanning bed restrictions.

Now, I must inform you that this is my last column, but I plan to continue writing. Over the past 6 years, I have been able to cover a wide range of topics ranging from human trafficking and the American Medical Association, to the many problems faced by small practices. I have enjoyed myself hugely. To quote Douglas Adams, from The Hitchhiker’s Guide to the Galaxy, “So long and thanks for all the fish!” Keep in touch at [email protected].

The Food and Drug Administration on Nov. 12 approved ropeginterferon alfa-2b-njft (Besremi), a monopegylated, long-acting interferon, for adults with polycythemia vera, according to an agency press release.

Besremi has a longer half-life than do other pegylated interferon-alfas, allowing for dosing every 2 weeks instead of weekly. If red blood cell counts remain normal for a year, patients have the option of switching to once-monthly dosing. As with similar products, Besremi is self-administered as a subcutaneous injection.

It’s the first interferon approved in the United States specifically for polycythemia vera. Besremi is also approved for upfront therapy, unlike FDA’s first approval for the condition, the oral JAK inhibitor ruxolitinib (Jakafi), which is indicated only after hydroxyurea failure.

Taiwan-based maker PharmaEssentia said in another press release that it will roll Besremi out to the U.S. market in the coming weeks.

“As we begin working closely with the community to integrate this important treatment into clinical practice, we also continue to expand our scientific efforts to unlock the full potential of our pioneering molecule,” said Ko-Chung Lin, PhD, the company’s CEO.

As for unlocking the full potential, Besremi is under investigation for other interferon indications, including myelofibrosis, leukemia, and chronic hepatitis.

The FDA’s approval was based on results in 51 adults treated for an average of 5 years; 31 (61%) had a complete hematologic response, defined as a hematocrit below 45% with no phlebotomy for at least 2 months, plus normal platelet and white cell counts, normal spleen size, and no blood clots.

“Noninferiority to hydroxyurea regarding haematological response and normal spleen size was not shown at 12 months. However, response to ropeginterferon alfa-2b continued to increase over time with improved responses compared with hydroxyurea at 36 months,” investigators noted in an earlier report (Lancet Haematol. 2020 Mar;7[3]:e196-e208).

Besremi carries the same boxed warning as those of peginterferon alfa-2b (Pegintron) and peginterferon alfa-2a (Pegasys), which notes the risk of life-threatening neuropsychiatric, autoimmune, ischemic, and infectious disorders. Related contraindications include severe depression and other psychiatric problems; liver impairment; serious or untreated autoimmune disease, and immunosuppression following organ transplant.

Influenza-like illness, arthralgia, fatigue, pruritis, nasopharyngitis, and musculoskeletal pain were the most common adverse events in studies, occurring in over 40% of subjects. Urinary tract infections, transient ischemic attacks, and depression were the most frequent serious complications, occurring in over 4%.

Labeling also notes the risk for fetal harm and the need for effective contraception.

Besremi was approved in Europe in 2019 and is approved in Taiwan and South Korea.

Polycythemia vera is a rare condition thought to be caused by acquired bone marrow stem cell mutations that trigger an overproduction of red blood cells. Patients are at increased risk of blood clots and emboli, and subsequent heart attacks, strokes, and other problems. There’s also the risk of transformation to secondary myelofibrosis or leukemia.

The Food and Drug Administration is reminding health care providers about the risk of major complications if cardiac perforation occurs during leadless pacemaker implantation.

Cardiac perforation is a rare complication and the overall risk associated with leadless pacemaker implantation appears similar to that with traditional transvenous pacemakers, the agency says. However, premarket clinical studies of the Micra leadless pacemaker (Medtronic) suggested major complications related to cardiac perforation appear to be more severe for those receiving a leadless pacemaker.

“Information from real-world use suggests that cardiac perforations associated with Micra leadless pacemakers are more likely to be associated with serious complications, such as cardiac tamponade or death, than with traditional pacemakers,” the FDA said Nov. 17 in a letter to health care professionals.

“The FDA is bringing this information to your attention as a reminder and to encourage you to report leadless pacemaker cardiac perforations and complications related to perforation to the manufacturer and the FDA,” it notes.

The Micra Transcatheter Pacing System in 2015 was the first leadless pacemaker approved in Europe, and was approved in the United States the following year with a mandated postapproval study to help assess continued safety and efficacy. The Micra device is currently the only approved leadless pacemaker in the United States.

The FDA continues to evaluate outcomes in patients who receive leadless pacing systems and recommends that health care providers discuss the risks and benefits of available pacing system options with patients as part of shared clinical decision-making.

Providers are advised to read and carefully follow the instructions for use and training for Medtronic’s Micra pacemaker.

Any adverse events or suspected adverse events related to the Micra Transcatheter Pacing System or any other pacemaker systems should be reported to the FDA through MedWatch, its adverse-event reporting program.

Providers are advised to read and carefully follow the instructions for use and training for Medtronic’s Micra pacemaker.

Any adverse events or suspected adverse events related to the Micra Transcatheter Pacing System or any other pacemaker systems should be reported to the FDA through MedWatch, its adverse-event reporting program.

Cardiac perforation is a rare complication and the overall risk associated with leadless pacemaker implantation appears similar to that with traditional transvenous pacemakers, the agency says. However, premarket clinical studies of the Micra leadless pacemaker (Medtronic) suggested major complications related to cardiac perforation appear to be more severe for those receiving a leadless pacemaker.

“Information from real-world use suggests that cardiac perforations associated with Micra leadless pacemakers are more likely to be associated with serious complications, such as cardiac tamponade or death, than with traditional pacemakers,” the FDA said Nov. 17 in a letter to health care professionals.

“The FDA is bringing this information to your attention as a reminder and to encourage you to report leadless pacemaker cardiac perforations and complications related to perforation to the manufacturer and the FDA,” it notes.

The Micra Transcatheter Pacing System in 2015 was the first leadless pacemaker approved in Europe, and was approved in the United States the following year with a mandated postapproval study to help assess continued safety and efficacy. The Micra device is currently the only approved leadless pacemaker in the United States.
