Quantitative assessment of the extent of interstitial lung disease in patients with systemic sclerosis and levels of certain proteins in bronchoalveolar lavage samples have potential for predicting mortality and disease progression, according to two analyses of data from the Scleroderma Lung Study I and II.

The analyses, presented at the annual European Congress of Rheumatology, aim to improve current prognostic abilities in patients with systemic sclerosis–interstitial lung disease (SSc-ILD). Although forced vital capacity is commonly used as a biomarker for survival in many SSc-ILD trials, other factors can affect FVC, such as respiratory muscle weakness and skin fibrosis. Further, FVC correlates poorly with patient-reported outcomes, explained first author Elizabeth Volkmann, MD, director of the scleroderma program at the University of California, Los Angeles, and the founder and codirector of the UCLA connective tissue disease–related interstitial lung disease program.

Dr. Volkmann presented two studies that investigated the potential of radiographic and protein biomarkers for predicting mortality and identifying patients at risk for ILD progression. The biomarkers may also help to identify patients who would benefit most from immunosuppressive therapy.

The first study found that tracking the quantitative extent of ILD (QILD) over time with high-resolution CT (HRCT) predicted poorer outcomes and could therefore act as a surrogate endpoint for mortality among patients with SSc-ILD. The other study identified associations between specific proteins from bronchoalveolar lavage (BAL) and the likelihood of ILD progression, although some associations were treatment dependent.

Jacob M. van Laar, MD, PhD, professor of rheumatology at the University Medical Center Utrecht (the Netherlands), who was not involved in the study, found the results intriguing and noted the importance of further validation in research before these biomarkers are considered for clinical use.

“It would be wonderful if we can tailor therapy based on BAL biomarkers in the future, as clinicians often struggle to decide on selection, timing, and duration of immunosuppressive treatment,” Dr. van Laar told this news organization. “This has become even more relevant with the introduction of new drugs such as nintedanib.”
 

Extent of ILD progression as a surrogate for mortality

Scleroderma Lung Study I involved 158 patients with SSc-ILD who were randomly assigned to receive either cyclophosphamide or placebo for 12 months. Scleroderma Lung Study II included 142 patients with SSc-ILD who were randomly assigned to receive either mycophenolate for 24 months or cyclophosphamide for 12 months followed by placebo for 12 months.

The researchers calculated QILD in the whole lung at baseline, at 12 months in the first trial, and at 24 months in the second trial. However, only 82 participants from the first trial and 90 participants from the second trial underwent HRCT. Demographic and disease characteristics were similar between the two groups on follow-up scans.

Follow-up continued for 12 years for patients in the first trial and 8 years in the second. The researchers compared survival rates between the 41% of participants from the first study and 31% of participants from the second study who had poorer QILD scores (at least a 2% increase) with the participants who had stable or improved scores (less than 2% increase).

Participants from both trials had significantly poorer long-term survival if their QILD scores had increased by at least 2% at follow-up (P = .01 for I; P = .019 for II). The association was no longer significant after adjustment for baseline FVC, age, and modified Rodnan skin score in the first trial (hazard ratio, 1.98; P = .089), but it remained significant for participants of the second trial (HR, 3.86; P = .014).

“Data from two independent trial cohorts demonstrated that radiographic progression of SSc-ILD at 1 and 2 years is associated with worse long-term survival,” Dr. Volkmann told attendees.

However, FVC did not significantly predict risk of mortality in either trial.

“To me, the most striking finding from the first study was that change in QILD performed better as a predictor of survival than change in FVC,” Dr. van Laar said in an interview. “This indicates QILD is fit for purpose and worth including in future clinical trials.”

Limitations of the study included lack of HRCT for all participants in the trials and the difference in timing (1 year and 2 years) of HRCT assessment between the two trials. The greater hazard ratio for worsened QILD in the second trial may suggest that assessment at 2 years provides more reliable data as a biomarker, Dr. Volkmann said.

“QILD may represent a better proxy for how a patient feels, functions, and survives than FVC,” she said.
 

Treatment-dependent biomarkers for worsening lung fibrosis

In the second study, the researchers looked for any associations between changes in the radiographic extent of SSc-ILD and 68 proteins from BAL.

“Being able to risk-stratify patients with interstitial lung disease at the time of diagnosis and predict which patients are likely to have a stable versus progressive disease course is critical for making important treatment decisions for these patients,” Dr. Volkmann told attendees.

The second study she presented involved Scleroderma Lung Study I. Of the 158 participants, 144 underwent a bronchoscopy, yielding BAL protein samples from 103 participants. The researchers determined the extent of radiographic fibrosis in the whole lung with quantitative imaging analysis of HRCT of the chest at baseline and 12 months.

Although the researchers identified several statistically significant associations between certain proteins and changes in radiographic fibrosis, “baseline protein levels were differentially associated with the course of ILD based on treatment status,” she told attendees.

For example, increased levels of the following proteins were linked to poor radiographic fibrosis scores for patients who received placebo:

• Granulocyte-macrophage colony-stimulating factor
• Interleukin-1
• Monocyte chemoattractant protein–3
• Chemokine ligand–5
• Transforming growth factor–beta
• Hepatocyte growth factor
• Stem cell factor
• IL-4
• TGF-alpha

Yet increases in these proteins predicted improvement in radiographic fibrosis in patients who had taken cyclophosphamide.

Independently of treatment, the researchers also identified an association between higher levels of fractalkine and poorer radiographic fibrosis scores and between higher IL-7 levels and improved radiographic fibrosis scores.

After adjusting for treatment arm and baseline severity of ILD, significant associations remained between change in radiographic fibrosis score and IL-1, MCP-3, surfactant protein C, IL-7 and CCL-5 levels.

“Biomarker discovery is really central to our ability to risk stratify patients with SSc-ILD,” Dr. Volkmann told attendees. “Understanding how biomarkers predict outcomes in treated and untreated patients may improve personalized medicine to patients with SSc-ILD and could also reveal novel treatment targets.”

Dr. van Laar said in an interview that this study’s biggest strength lay in its large sample size and in the comprehensiveness of the biomarkers studied.

“The findings are interesting from a research perspective and potentially relevant for clinical practice, but the utility of measuring biomarkers in BAL should be further studied for predictive value on clinical endpoints,” Dr. van Laar said. “BAL is an invasive procedure [that] is not routinely done.”

The research was funded by the National Institutes of Health. Dr. Volkmann has consulted for Boehringer Ingelheim and received grant funding from Corbus, Forbius, and Kadmon. Dr. van Laar has received grant funding or personal fees from Arthrogen, Arxx Therapeutics, AstraZeneca, Bristol-Myers Squibb, Eli Lilly, Gesynta, Leadiant, Merck Sharp & Dohme, Roche, Sanofi, and Thermofisher.

To the Editor:

Argyria is a rare disease caused by chronic exposure to products with high silver content (eg, oral ingestion, inhalation, percutaneous absorption). With time, the blood levels of silver surpass the body’s renal and hepatic excretory capacities that lead to silver granules being deposited in the skin and internal organs, including the liver, spleen, adrenal glands, and bone marrow.¹ The cutaneous deposition results in a blue or blue-gray pigmentation of the skin, mucous membranes, and nails. Intervals of exposure that span from 8 months to 5 years prior to symptom onset have been described in the literature.² The discoloration that results often is permanent, with no established way of effectively removing silver deposits from the tissue.³

A 22-year-old autistic man, who was completely dependent on his mother’s care, presented to the emergency department with a primary concern of abdominal pain. The mother reported that he was indicating abdominal pain by motioning to his stomach for the last 5 days. The mother also reported he did not have a bowel movement during this time, and she noticed his hands were shaking. Prior to presentation, the mother had given him 2 enemas and had him on a 3-day strict liquid fast consisting of water, lemon juice, cayenne pepper, honey, and orange juice. Notably, the mother had a strong history of using naturopathic remedies for treatment of her son’s ailments.

On admission, the patient was stable. There was a 2-point decrease in the patient’s body mass index over the last month. Initial serum electrolytes were highly abnormal with a serum sodium level of 124 mEq/L (reference range, 135–145 mEq/L), blood urea nitrogen of 3 mg/dL (reference range, 7–20 mg/dL), creatinine of 0.77 mg/dL (reference range, 0.74–1.35 mg/dL), and lactic acid of 2.1 mEq/L (reference range, 0.5–1 mEq/L). Serum osmolality was 272 mOsm/kg (reference range, 275–295 mOsm/kg). Urine osmolality was 114 mOsm/kg (reference range, 500–850 mOsm/kg) with a low-normal urine sodium level of 41 mmol/24 hr (reference range, 40–220 mmol/24 hr). Abnormalities were felt to be secondary to malnutrition from the strict liquid diet (blood urea nitrogen and creatinine ratio of 3:1 suggestive of notable protein calorie malnutrition). The patient was given 1 L of normal saline in the emergency department, with further fluids held so as not to increase serum sodium level too rapidly. A regular diet was started.

Physical examination revealed dry mucosal membranes but otherwise was unremarkable. Active bowel sounds were noted, as well as a soft, nontender, and nondistended abdomen; however, when examining the patient’s hands for reported shaking, a distinct abnormality of the nails was noticed. The patient had slate blue discoloration of the lunula, along with hyperpigmented violaceous discoloration of the proximal nail bed on all 10 fingernails (Figure 1). No abnormalities were seen on the toenails. The mother had a distinct bluish gray discoloration of the face as well as similar nail findings (Figure 2), strongly suggestive of colloidal silver use. An urgent serum silver level was ordered on the patient as well as a heavy metal panel. The mother was found applying numerous “natural remedies” to the patient’s skin while in the hospital, including a liquid spray and lotion, both in unmarked bottles. At that time, the mother was informed that no external supplements should be applied to her son. The serum silver level was elevated substantially at 94.3 ng/mL (reference range, <1.0 ng/mL). When the mother was confronted, she initially denied use of silver but later admitted to notable silver content in the cream she was applying to her son’s skin. The mother reported that she read online that colloidal silver had been historically used to cure numerous ailments and she was ordering products from an online company. She was counseled on the dangers of both topical application and ingestion of silver, and all supplements were removed from the home.

Initial differential diagnoses for altered nail pigmentation include drug-induced causes, systemic diseases, cyanosis, and exposure to metals.⁷ The most commonly indicated medications resulting in blue nail pigment changes include antimalarials, minocycline, zidovudine, and phenothiazine. Systemic diseases that may cause blue nail color change include Wilson disease, hemochromatosis, Addison disease, methemoglobinemia, and alkaptonuria.⁷ Metals include gold, mercury, arsenic, bismuth, lead, and silver.⁴ After a thorough review of the patient’s medications and lack of support for any underlying disease process, contact with metals, particularly silver, was ranked highly on our differential list. In support of this theory, the mother’s bluish gray facial skin led to high clinical suspicion that she was ingesting colloidal silver and also was exposing her son to silver.

Treatment of argyria is challenging but first and foremost involves discontinuation of the source of chronic silver exposure. Unfortunately, the discoloration of generalized argyria often is permanent. Sunscreen can be used to help prevent any further darkening of pigment. The pigment in localized argyria has been reported to slowly fade with time, and there also have been reports of successful treatment using a low-fluence Q-switched 1064-nm Nd:YAG laser.⁸

Initial serum electrolytes were highly abnormal with a serum sodium level of 124 mEq/L (reference range, 135–145 mEq/L), blood urea nitrogen of 3 mg/dL (reference range, 7–20 mg/dL), creatinine of 0.77 mg/dL (reference range, 0.74–1.35 mg/dL), and lactic acid of 2.1 mEq/L (reference range, 0.5–1 mEq/L). Serum osmolality was 272 mOsm/kg (reference range, 275–295 mOsm/kg). Urine osmolality was 114 mOsm/kg (reference range, 500–850 mOsm/kg) with a low-normal urine sodium level of 41 mmol/24 hr (reference range, 40–220 mmol/24 hr). Abnormalities were felt to be secondary to malnutrition from the strict liquid diet (blood urea nitrogen and creatinine ratio of 3:1 suggestive of notable protein calorie malnutrition). The patient was given 1 L of normal saline in the emergency department, with further fluids held so as not to increase serum sodium level too rapidly. A regular diet was started.

Physical examination revealed dry mucosal membranes but otherwise was unremarkable. Active bowel sounds were noted, as well as a soft, nontender, and nondistended abdomen; however, when examining the patient’s hands for reported shaking, a distinct abnormality of the nails was noticed. The patient had slate blue discoloration of the lunula, along with hyperpigmented violaceous discoloration of the proximal nail bed on all 10 fingernails (Figure 1). No abnormalities were seen on the toenails. The mother had a distinct bluish gray discoloration of the face as well as similar nail findings (Figure 2), strongly suggestive of colloidal silver use. An urgent serum silver level was ordered on the patient as well as a heavy metal panel. The mother was found applying numerous “natural remedies” to the patient’s skin while in the hospital, including a liquid spray and lotion, both in unmarked bottles. At that time, the mother was informed that no external supplements should be applied to her son. The serum silver level was elevated substantially at 94.3 ng/mL (reference range, <1.0 ng/mL). When the mother was confronted, she initially denied use of silver but later admitted to notable silver content in the cream she was applying to her son’s skin. The mother reported that she read online that colloidal silver had been historically used to cure numerous ailments and she was ordering products from an online company. She was counseled on the dangers of both topical application and ingestion of silver, and all supplements were removed from the home.

Initial differential diagnoses for altered nail pigmentation include drug-induced causes, systemic diseases, cyanosis, and exposure to metals.⁷ The most commonly indicated medications resulting in blue nail pigment changes include antimalarials, minocycline, zidovudine, and phenothiazine. Systemic diseases that may cause blue nail color change include Wilson disease, hemochromatosis, Addison disease, methemoglobinemia, and alkaptonuria.⁷ Metals include gold, mercury, arsenic, bismuth, lead, and silver.⁴ After a thorough review of the patient’s medications and lack of support for any underlying disease process, contact with metals, particularly silver, was ranked highly on our differential list. In support of this theory, the mother’s bluish gray facial skin led to high clinical suspicion that she was ingesting colloidal silver and also was exposing her son to silver.

Treatment of argyria is challenging but first and foremost involves discontinuation of the source of chronic silver exposure. Unfortunately, the discoloration of generalized argyria often is permanent. Sunscreen can be used to help prevent any further darkening of pigment. The pigment in localized argyria has been reported to slowly fade with time, and there also have been reports of successful treatment using a low-fluence Q-switched 1064-nm Nd:YAG laser.⁸

Squamoid eccrine ductal carcinoma (SEDC) is an aggressive underrecognized cutaneous malignancy of unknown etiology.¹ It is most likely to occur in sun-exposed areas of the body, most commonly the head and neck. Risk factors include male sex, increased age, and chronic immunosuppression.^1-4 Current reports suggest that SEDC is likely a high-grade subtype of squamous cell carcinoma (SCC) with a high risk for local recurrence (25%) and metastasis (13%).^1,3,5,6 There are as few as 56 cases of SEDC reported in the literature; however, the number of cases may be closer to 100 due to SEDC being classified as either adenosquamous carcinoma of the skin or ductal eccrine carcinoma with squamous differentiation.¹

Clinically, SEDC mimics keratinocyte carcinomas. Histologically, SEDC is biphasic, with a superficial portion resembling well-differentiated SCC and a deeply invasive portion having infiltrative irregular cords with ductal differentiation. Perineural invasion (PNI) frequently is present. Multiple connections to the overlying epidermis also can be seen, serving as a subtle clue to the diagnosis on broad superficial specimens.^1-3 Due to superficial sampling, approximately 50% of reported cases are misdiagnosed as SCC during the initial biopsy.⁴ The diagnosis of SEDC often is made during complete excision when deeper tissue is sampled. Establishing an accurate diagnosis is important given the more aggressive nature of SEDC compared with SCC and its proclivity for PNI.^1,3,6 The purpose of this review is to increase awareness of this underrecognized entity and describe the histologic findings that help distinguish SEDC from SCC.

Patient Chart Review

We reviewed chart notes as well as frozen and formalin-fixed paraffin-embedded tissue sections from all 5 patients diagnosed with SEDC at a single institution between November 2018 and May 2020. The mean age of patients was 81 years, and 4 were male. Four of the patients presented for MMS with a preoperative diagnosis of SCC per the original biopsy results. Only 1 patient had a preoperative diagnosis of SEDC. The details of each case are recorded in the Table. All tumors were greater than 2 cm in diameter on initial presentation, were located on the head, and clinically resembled keratinocyte carcinoma with either a nodular or plaquelike appearance (Figure 1).

Intraoperative histologic examination of the excised tissue revealed a biphasic pattern consisting of superficial SCC features overlying deeper dermal and subcutaneous infiltrative malignant ductal elements with gland formation in all 5 patients (Figures 2–4). Immunohistochemical staining with cytokeratin AE1/AE3 revealed thin strands of carcinoma in the mid to deeper dermis with squamous differentiation and eccrine ductal differentiation (Figure 5), thus confirming the diagnosis in all 5 patients.

Literature Review

A PubMed review of the literature using the search term squamoid eccrine ductal carcinoma resulted in 28 articles, 19 of which were included in the review based on inclusion criteria (original articles available in English, in full text, and pertained to SEDC). Our review yielded 56 cases of SEDC.^1-19 The mean age of patients with SEDC was 72 years. The number of male and female cases was 52% (29/56) and 48% (27/56), respectively. The most common location of SEDC was on the head or neck (71% [40/56]), followed by the extremities (19% [11/56]). Immunosuppression was noted in 9% (5/56) of cases. Wide local excision was the most commonly employed treatment modality (91% [51/56]), with MMS being used in 4 patients (7%). Adjuvant radiation was reported in 5% (3/56) of cases. Perineural invasion was reported in 34% (19/56) of cases. Recurrence was seen in 23% (13/56) of cases, with a mean time to recurrence of 10.4 months. Metastasis to regional lymph nodes was observed in 13% (7/56) of cases, with 7% (4/56) of those cases having distant metastases.

Comment

Squamoid eccrine ductal carcinoma was successfully treated with MMS in all 5 of the patients we reviewed. Recognition of a distinct biphasic pattern consisting of squamous differentiation superficially with epidermal connection overlying deeper dermal and subcutaneous infiltrative malignant ductal elements with gland formation should lead to consideration of this diagnosis. A thorough inspection for PNI also should be performed, as this finding was present in all of 5 cases and in 34% of reported cases in our literature review.

The differential diagnosis for SEDC includes SCC, metastatic adenocarcinoma with squamoid features, and eccrine tumors, including eccrine poroma, microcystic adnexal carcinoma (MAC), and porocarcinoma with squamous differentiation. The combination of histologic features with the immunoexpression profile of carcinoembryonic antigen (CEA), epithelial membrane antigen (EMA), cytokeratin (CK) 5/6, and p63 can effectively exclude the other entities in the differential and confirm the diagnosis of SEDC.^1,3,4 While the diagnosis of SEDC relies on the specific histologic features of multiple surface attachments and superficial squamoid changes with deep ductular elements, immunohistochemistry can nonetheless be adjunctive in difficult cases. Positive immunohistochemical staining for CEA and EMA can help to highlight and delineate true glandular elements, whereas CK5/6 highlights the overall contour of the tumor, displaying more clearly the multiple epidermal attachments and the subtle infiltrative nature of the deeper components of invasive cords and ducts. In addition, the combination of CK5/6 and p63 positivity supports the primary cutaneous nature of the lesion rather than metastatic adenocarcinoma.^13,20 Other markers of eccrine secretory coils, such as CK7, CAM5.2, and S100, also are sometimes used for confirmation, some of which can aid in distinction from noneccrine sweat gland differentiation, as CK7 and CAM5.2 are negative in both luminal and basal cells of the dermal duct while being positive within the secretory coil, and S100 protein is expressed within eccrine secretory coil but negative within the apocrine sweat glands.^2,4,21

The clinical findings from our chart review corroborated those reported in the literature. The mean age of SEDC in the 5 patients we reviewed was 81 years, and all cases presented on the head, consistent with the findings observed in the literature. Although 4 of our cases were male, there may not be a difference in risk based on sex as previously thought.¹ Our literature review revealed an almost equivalent percentage of male and female cases, with 52% being male.

Immunosuppression has been associated with an increased risk for SEDC. Our literature review revealed that approximately 9% (5/56) of cases occurred in immunosuppressed individuals. Two of these reported cases were in the setting of underlying chronic lymphocytic leukemia, 2 in individuals with a history of organ transplant, and 1 treated with azathioprine for myasthenia gravis.^2,4,10,12,13 Our chart review supported this correlation, as all 5 patients had a medical history potentially consistent with being in an immunocompromised state (Table). Notably, patient 5 represents a unique case of SEDC occurring in the setting of HIV. The patient had HIV for 33 years, with his most recent CD4⁺ count of 794 mm³ and HIV-1 RNA load of 35 copies/mL. Given that HIV-positive individuals may have more than a 2-fold increased risk of SCC, a greater degree of suspicion for SEDC should be maintained for these patients.^22,23

The etiology of SEDC is controversial but is thought to be either an SCC arising from eccrine glands or a variant of eccrine carcinoma with extensive squamoid differentiation.^{4,6,13,14,17,24} While SEDC certainly appears to share the proclivity for PNI with the malignant eccrine tumor MAC, it is simultaneously quite distinct, demonstrating nuclear pleomorphism and mitotic activity, both of which are lacking in the bland nature of MACs.^12,25

The exact prevalence of SEDC is difficult to ascertain because of its frequent misdiagnosis and variable nomenclature used within the literature. Most reported cases of SEDC are mistakenly diagnosed as SCC on the initial shave or punch biopsy because of superficial sampling. This also was the case in 4 of the patients we reviewed. In addition, there are reported cases of SEDC that were referred to by the investigators as cutaneous adenosquamous carcinoma (cASC), among other descriptors, such as ductal eccrine carcinoma with squamous differentiation, adnexal carcinoma with squamous and ductal differentiation, and syringoid eccrine carcinoma.^26-32 While the World Health Organization classifies SEDC as a distinct variant of cASC, which is a rare variant of SCC in itself, the 2 can be differentiated. Despite the similar clinical and histologic features shared between cASC and SEDC, the neoplastic aggregates in SEDC exhibit ductal differentiation containing lumina positive for CEA and EMA.⁴ Overall, we favor the term squamoid eccrine ductal carcinoma, as there has recently been more uniformity for the designation of this disease entity as such.

It is unclear whether the high incidence of local recurrence (23% [13/56]) of SEDC reported in the literature is related to the treatment modality employed (ie, wide local excision) or due to the innate aggressiveness of SEDC.^1,3,5 The literature has shown that MMS has lower recurrence rates than other treatments at 5-year follow-up for SCC (3.1%–5%) and eccrine carcinomas (0%–5%).^33,34 Although studies assessing tumor behavior or comparing treatment modalities are limited because of the rarity and underrecognition of SEDC, MMS has been used several times for SEDC with only 1 recurrence reported.^4,13,17,24 Given that all 5 of the patients we reviewed required more than 1 Mohs stage for complete tumor clearance and none demonstrated evidence of recurrence or metastasis (Table), we recommend MMS as the treatment of choice for SEDC.

Conclusion

Squamoid eccrine ductal carcinoma is a rare but likely underdiagnosed cutaneous tumor of uncertain etiology. Because of its propensity for recurrence and metastasis, excision of SEDC with complete circumferential peripheral and deep margin assessment with close follow-up is recommended.

Granuloma annulare (GA) is a benign, cutaneous, granulomatous disease of unclear etiology. Typically, GA presents in young adults as asymptomatic, annular, flesh-colored to pink papules and plaques, commonly on the upper and lower extremities. Histologically, GA is characterized by mucin deposition, palisading or an interstitial granulomatous pattern, and collagen and elastic fiber degeneration.¹

Granuloma annulare has been associated with various medications and medical conditions, including diabetes mellitus, hyperlipidemia, thyroid disease, and HIV.¹ More recently, immune-checkpoint inhibitors (ICIs) have been reported to trigger GA.² We report a case of nivolumab-induced GA in a 54-year-old woman.

Case Report

A 54-year-old woman presented with an itchy rash on the upper extremities, face, and chest of 4 months’ duration. The patient noted that the rash started on the hands and progressed to include the arms, face, and chest. She also reported associated mild tenderness. She had a history of stage IV non–small-cell lung carcinoma with metastases to the ribs and adrenal glands. She had been started on biweekly intravenous infusions of the ICI nivolumab by her oncologist approximately 1 year prior to the current presentation after failing a course of conventional chemotherapy. The most recent positron emission tomography–computed tomography scan 1 month prior to presentation showed a stable lung mass with radiologic disappearance of metastases, indicating a favorable response to nivolumab. The patient also had a history of hypothyroidism and depression, which were treated with oral levothyroxine 75 μg once daily and oral sertraline 50 mg once daily, respectively, both for longer than 5 years.

Physical examination revealed annular, erythematous, flat-topped papules, some with surmounting fine scale, coalescing into larger plaques along the dorsal surface of the hands and arms (Figure 1) as well as the forehead and chest. A biopsy of a papule on the dorsal aspect of the left hand revealed nodules of histiocytes admixed with Langerhans giant cells within the dermis; mucin was noted centrally within some nodules (Figure 2). Periodic acid–Schiff staining was negative for fungal elements compared to control. Polarization of the specimen was negative for foreign bodies. The biopsy findings therefore were consistent with a diagnosis of GA.

Comment

Discovery of specific immune checkpoints in tumor-induced immunosuppression revolutionized oncologic therapy. An example is the programmed cell-death protein 1 (PD-1) receptor that is expressed on activated immune cells, including T cells and macrophages.^3,4 Upon binding to the PD-1 ligand (PD-L1), T-cell proliferation is inhibited, resulting in downregulation of the immune response. As a result, tumor cells have evolved to overexpress PD-L1 to evade immunologic detection.³ Nivolumab, a fully human IgG4 antibody to PD-1, has emerged along with other ICIs as effective treatments for numerous cancers, including melanoma and non–small-cell lung cancer. By disrupting downregulation of T cells, ICIs improve immune-mediated antitumor activity.³

However, the resulting immunologic disturbance by ICIs has been reported to induce various cutaneous and systemic immune-mediated adverse reactions, including granulomatous reactions such as sarcoidosis, GA, and a cutaneous sarcoidlike granulomatous reaction.^1,2,5,6 Our patient represents a rare case of nivolumab-induced GA.

Recent evidence suggests that GA might be caused in part by a cell-mediated hypersensitivity reaction that is regulated by a helper T cell subset 1 inflammatory reaction. Through release of cytokines by activated CD4⁺ T cells, macrophages are recruited, forming the granulomatous pattern and secreting enzymes that can degrade connective tissue. Nivolumab and other ICIs can thus trigger this reaction because their blockade of PD-1 enhances T cell–mediated immune reactions.² In addition, because macrophages themselves also express PD-1, ICIs can directly enhance macrophage recruitment and proliferation, further increasing the risk of a granulomatous reaction.⁴

Interestingly, cutaneous adverse reactions to nivolumab have been associated with improved survival in melanoma patients.⁷ The nature of this association with granulomatous reactions in general and with GA specifically remains to be determined.

Conclusion

Since the approval of the first PD-1 inhibitors, pembrolizumab and nivolumab, in 2014, other ICIs targeting the immune checkpoint pathway have been developed. Newer agents targeting PD-L1 (avelumab, atezolizumab, and durvalumab) were recently approved. Additionally, cemiplimab, another PD-1 inhibitor, was approved by the US Food and Drug Administration in 2018 for the treatment of advanced cutaneous squamous cell carcinoma.⁸ Indications for all ICIs also have expanded considerably.³ Therefore, the incidence of immune-mediated adverse reactions, including GA, is bound to increase. Physicians should be cognizant of this association to accurately diagnose and effectively treat adverse reactions in patients who are taking ICIs.

Granuloma annulare (GA) is a benign, cutaneous, granulomatous disease of unclear etiology. Typically, GA presents in young adults as asymptomatic, annular, flesh-colored to pink papules and plaques, commonly on the upper and lower extremities. Histologically, GA is characterized by mucin deposition, palisading or an interstitial granulomatous pattern, and collagen and elastic fiber degeneration.¹

Granuloma annulare has been associated with various medications and medical conditions, including diabetes mellitus, hyperlipidemia, thyroid disease, and HIV.¹ More recently, immune-checkpoint inhibitors (ICIs) have been reported to trigger GA.² We report a case of nivolumab-induced GA in a 54-year-old woman.

Inpatient care utilization for hidradenitis suppurativa (HS) was higher for Black and Hispanic patients, compared with White patients, in an analysis of the 2012-2017 National Inpatient Sample.

The differences occurred despite Black and Hispanic patients being younger at the time of admission than White patients, and may reflect increased disease severity and management challenges in these patients with skin of color, Nishadh Sutaria, BS, a medical student at Tufts University, Boston, said at the annual Skin of Color Society symposium. “They may also reflect social inequities in access to dermatologists, with racial and ethnic minorities using inpatient services in lieu of outpatient care.”

Mr. Sutaria and coinvestigators, led by Shawn Kwatra, MD, of Johns Hopkins University, Baltimore, identified 8,040 HS admissions for White patients, 16,490 Black patients, and 2,405 for Hispanic patients during the 5-year period.

Black and Hispanic patients were significantly younger than White patients, with a mean age of 38.1 years and 35 years, respectively, compared with 42 years for White patients (P < .001 in each case). Compared with White patients, Black patients had more procedures (2.03 vs. 1.84, P = .006), a longer length of stay (5.82 days vs. 4.97 days, P = .001), and higher cost of care ($46,119 vs. $39,862, P = .010). Compared with White patients, Hispanic patients had higher cost of care ($52,334 vs. $39,862, P = .004).

“In these models, Black patients stayed almost a full day longer and accrued a charge of $8,000 more than White patients, and Hispanic patients stayed about a half-day longer and accrued a charge of almost $15,000 more than White patients,” Mr. Sutaria said.

In a multilinear regression analysis adjusting for age, sex, and insurance type, Black race correlated with more procedures, higher length of stay, and higher cost of care, and Hispanic ethnicity with more procedures and higher cost of care.

Prior research has shown that Black patients may be disproportionately affected by HS. A 2017 analysis of electronic health record data for tens of millions of patients nationally, for instance, showed an incidence of HS that was over 2.5 times greater in Blacks than Whites. And a recent analysis of electronic data in Wisconsin for patients with an HS diagnosis and 3 or more encounters for the disease showed that Blacks are more likely to have HS that is Hurley Stage 3, the most severe type.

Increased severity “has not been explicitly shown in Hispanic patients,” Dr. Kwatra said in an interview, “[but] there is a strong relationship between obesity/metabolic syndrome with HS. Because Hispanic patients have higher rates of obesity and metabolic syndrome, it’s [thought] that they may have more severe HS.”

HS patients with skin of color are underrepresented in clinical trials, he said. “Severe HS can be difficult to treat because there are few effective treatments,” he said, noting that adalimumab is the only Food and Drug Administration–approved therapy.

The National Inpatient Sample is a publicly available, all-payer inpatient care database developed for the Agency for Healthcare Research and Quality’s Healthcare Cost and Utilization Project.

Jack Resneck Jr., MD, a dermatologist in the San Francisco Bay area, is the new president-elect of the American Medical Association and will take over as president in June 2022

Known for his advocacy efforts – promoting telemedicine and digital health and fighting rising prescription drug prices, among other issues – he has testified in Congressional hearings on all those topics and other issues crucial for a functioning U.S. health care system.

Colleagues describe him as well informed, intelligent, and an excellent listener who is skilled at understanding all sides of difficult issues.

“I am committed to relentlessly advocating for physicians and patients on issues that matter most to us, and look forward to the continued meaningful advancements our AMA will make as we strive to improve the health of the nation,” Dr. Resneck said in a statement issued by the AMA. “Now more than ever, I am proud to be part of an AMA that is dedicated to driving the future of medicine, removing obstacles to patient care, and leading the charge to prevent chronic disease and confront public health crises – all while prioritizing our goal of eliminating longstanding health inequities.”

Dr. Resneck called this a “pivotal time of learning from the COVID-19 pandemic experience as we plan for the future of medicine and public health.”

“Jack is one of the most well-informed people I know,” Barbara L. McAneny, MD, president of the AMA from 2018 to 2019 and CEO of the New Mexico Cancer Center, Albuquerque, said in an interview. “Now that the pandemic is slowly decreasing, the underlying problems in our health care system will resurface. Jack understands how the insurance industry uses prior authorization and other techniques to harm physicians and patients. He is very well positioned to be a voice of reason that is sorely needed in today’s healthcare industry.”

David O. Barbe, MD, MHA, president of the World Medical Association and president of the AMA from 2017 to 2018, calls Dr. Resneck “extremely smart, very analytical. I think one of his great strengths is, he is an excellent listener and can capture the essence of all sides of the issues. He does a remarkable job at achieving consensus.” Dr. Barbe is a family physician in Mountain Grove, Mo.

Dr. Resneck has a long history of serving the AMA, the California Medical Association, and dermatology organizations such as the American Academy of Dermatology.

“Dr. Resneck’s exemplary leadership on a number of AAD/A committees and councils and as a member of the boards of directors has made a lasting impact on the academy, and he is poised to do the same as president-elect of the American Medical Association,” AAD president Ken Tomecki, MD, said in a statement provided by the AAD. “We congratulate Dr. Resneck on his achievement, and we’re proud to have a dermatologist serving as a leading voice in the house of medicine.”

First elected to the AMA board of trustees in 2014, Dr. Resneck held the office of board chair from 2018 to 2019. He was also chair of the AMA Council on Legislation and was a delegate to the AMA House of Delegates. He has had leadership roles in the California Society of Dermatology and Dermatologic Surgery, the American Academy of Dermatology and the California Medical Association. He is vice chair and professor of dermatology at the University of California, San Francisco, with a joint appointment at the Philip R. Lee Institute for Health Policy Studies.

As a researcher, his citation list includes numerous published studies about patient access to care, telemedicine, quality metrics, prior authorization, and public health. He is on the editorial board of the Journal of the American Academy of Dermatology and the board of directors of the National Quality Forum. His undergraduate degree in public policy is from Brown University, Providence, R.I. He earned his medical degree from UCSF, where he also completed an internal medicine internship, a residency training in dermatology and a health policy fellowship.

For physicians who are just starting out or thinking about moving, the “Land of 10,000 Lakes” could be the land of opportunity, according to a recent Medscape analysis.

In a ranking of the 50 states, Minnesota “claimed top marks for livability, low incidence of adverse actions against doctors, and the performance of its health system,” Shelly Reese wrote in Medscape’s “Best & Worst Places to Practice 2021.”

Minnesota is below average where it’s good to be below average – share of physicians reporting burnout and/or depression – but above average in the share of physicians who say they’re “very happy” outside of work, Medscape said in the annual report.

Second on this year’s list is Wisconsin, which benefits from low levels of malpractice payouts and adverse actions and a high level of livability. Third place went to Washington (called the most livable state in the country by U.S. News and World Report), fourth to Colorado (physicians happy at and outside of work, high retention rate for residents), and fifth to Utah (low crime rate, high quality of life), Medscape said.

At the bottom of the list for 2021 is West Virginia, where physicians “may confront a bevy of challenges” in the form of low livability, a high rate of adverse actions, and relatively high malpractice payouts, Ms. Reese noted in the report.

State number 49 is Louisiana, where livability is low, malpractice payouts are high, and more than half of physicians say that they’re burned out and/or depressed. New Mexico is 48th (very high rate of adverse actions, poor resident retention), Nevada is 47th (low marks for avoidable hospital use and disparity in care), and Rhode Island is 46th (high malpractice payouts, low physician compensation), Medscape said.

Continuing with the group-of-five theme, America’s three most populous states finished in the top half of the ranking – California 16th, Texas 11th, and Florida 21st – but New York and Pennsylvania, numbers four and five by population size, did not.

The rankings are based on states’ performance in 10 different measures, three of which were sourced from Medscape surveys – happiness at work, happiness outside of work, and burnout/depression – and seven from other organizations: adverse actions against physicians, malpractice payouts, compensation (adjusted for cost of living), overall health, health system performance, overall livability, resident retention.

Risankizumab (Skyrizi) was effective for treating psoriatic arthritis (PsA) in patients who did not respond to or who could not tolerate other biologics or standard disease-modifying antirheumatic drugs (DMARDs), according to a study presented at the annual European Congress of Rheumatology. It was also well tolerated.

“Treatment with risankizumab resulted in significantly greater improvements in signs and symptoms of psoriatic arthritis, including assessments of disease activity in joints and skin and patient-reported outcomes, compared with placebo, in patients who did not respond to or were intolerant to biologics or DMARDs,” reported Andrew Ostor, MD, of Monash University and Cabrini Hospital, both in Melbourne,. The safety profile was “consistent with that established for risankizumab in the treatment moderate to severe psoriasis,” he told attendees.

Risankizumab is approved in the United States for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy. It is a humanized immunoglobulin G1 monoclonal antibody that selectively inhibits cytokine interleukin-23 by binding to its p19 subunit. IL-23 has been implicated in the development of PsA.

This was a phase 3 trial with “promising results in line with the ACR 20 response [at least 20% improvement in American College of Rheumatology response criteria] of other biologics in psoriatic arthritis,” according to Gaëlle Varkas, MD, PhD, of the Ghent (the Netherlands) University VIB Center for Inflammation Research and the department of rheumatology, Ghent University Hospital. “Especially in patients with severe and/or refractory skin disease or inadequate response at the level of the joint to other DMARDs or biologics, risankizumab is filling a void,” Dr. Varkas, who was not involved in the research, said in an interview.

There were no major safety problems, although long-term data, especially in regard to cancer and cardiovascular effects, “are always of interest, as they can be missed in randomized, controlled trials,” she said. In addition, “efficacy in concomitant axial disease, uveitis, and inflammatory bowel disease might favor one treatment over the other.” Another clinically significant takeaway was risankizumab’s “better effect on skin psoriasis while maintaining the effect on joint manifestations.”
 

Details of 24-week trial results

The phase 3, randomized, placebo-controlled, double-blind KEEPSAKE 2 trial involved 444 patients who had active PsA, defined as at least five swollen joints and at least five tender joints. All the patients either had an inadequate response to or were intolerant of one or two biologics or at least one conventional synthetic DMARD.

A total of 224 patients were randomly assigned to receive 150 mg of subcutaneous risankizumab at baseline and at 4 and 16 weeks after baseline; 220 participants received placebo injections. The primary endpoint was the proportion of patients who had at least 20% improvement in American College of Rheumatology response criteria at week 24.

Demographic and clinical characteristics were similar in both groups at baseline. Among the participants, the total mean number of swollen joints was 13.3, and the total mean number of tender joints was 22.6. The participants had PsA for an average of 8.2 years. The proportions of patients previously treated with biologics and DMARDs were similar in both groups, as were the proportions of patients currently taking glucocorticoids, NSAIDs, or methotrexate or another DMARD. At week 24, there remained 199 patients in the placebo group and 215 in the risankizumab group.

Just over half (51.3%) of patients who took risankizumab achieved at least 20% improvement in their ACR 20 score, compared with just over a quarter (26.5%) of those who received placebo (P < .001). All secondary endpoints also showed statistically significant improvements (P < .001 for all except P < .009 for the Fatigue Functional Assessment of Chronic Illness Therapy–Fatigue [FACIT-Fatigue] secondary endpoint).

Scores on the Health Assessment Questionnaire–Disability Index were –0.22 in the risankizumab group and –0.05 in the placebo group (P < .001). In the risankizumab group, 55% of patients achieved at least a 90% reduction in scores on the Psoriasis Area Severity Index, compared with 10.2% of patients who received placebo. Similarly, 25.6% of patients who took risankizumab and 11.4% of patients who received placebo had minimal disease activity 24 weeks after baseline.

In the 36-item Short Form Health Survey Physical Component Summary, the score change among risankizumab patients was 5.9, compared with 2 among the patients who received placebo. The change in FACIT-Fatigue score was 4.9 for patients who took risankizumab and 2.6 for patients who received placebo.

The researchers also assessed how many patients achieved higher levels of response to treatment. At least a 50% improvement in ACR response criteria occurred among 26.3% of patients taking risankizumab and 9.3% of patients taking placebo (P < .001). ACR 70 responses were seen in 12% of patients receiving risankizumab, compared with 5.9% of patients receiving placebo (P < .02). In the risankizumab group, 72.5% of patients had resolution of dactylitis and 42.9% had resolution of enthesitis, compared with 42.1% and 30.4%, respectively, in the placebo group.

Serious adverse events occurred in 4% of patients who received risankizumab and 5.5% of patients who received placebo. Serious infections occurred in 0.9% of those receiving risankizumab and 2.3% of those receiving placebo. Rates of treatment-emergent adverse events were also similar in the risankizumab (55.4%) and placebo (54.8%) groups.

In response to a question about whether it was possible to identify patients who might respond better to IL-23 inhibitors, compared with IL-17 inhibitors, Dr. Ostor acknowledged that rheumatologic practice is not yet proficient at using biomarkers to direct therapy, so the benefit from these drugs lay elsewhere.

“What I think is great is the luxury of choice these days,” Dr. Ostor told attendees. “We have these agents now, including risankizumab, that do work very effectively across the spectrum of the clinical features. It’s just lovely to have these agents available that can truly make a difference to the clinical picture of the individual.”

The trial was sponsored by AbbVie. Dr. Ostor has received research grants or speaking or consulting fees from AbbVie, Bristol-Myers Squibb, Celgene, Janssen, Lilly, Merck, Novartis, Pfizer, Roche, Sanofi, and UCB. Dr. Varkas has received research grants or speaker fees from AbbVie and Pfizer.

Imagine this scenario: You are seated at the dinner table with your family when your smartphone buzzes; you look over, and the push notification reads “new biopsy results!”

PxHere

There is a sudden spill of icy anxiety down your spine as you pick up your phone in your shaking hands. It’s 6 p.m.; your doctor’s office is closed. You open the message, and your worst fears are confirmed ... the cancer is back.

Or is it? You’re not sure. The biopsy sure sounds bad. But you’re an English teacher, not a doctor, and you spend the rest of the night Googling words like “tubulovillous” and “high-grade dysplasia.” You sit awake, terrified in front of the computer screen desperately trying to make sense of the possibly life-changing results. You wish you knew someone who could help you understand; you consider calling your doctor’s emergency line, or your cousin who is an ophthalmologist – anybody who can help you make sense of the results.

Or imagine another scenario: you’re a trans teen who has asked your doctor to refer to you by your preferred pronouns. You’re still presenting as your birth sex, in part because your family would disown you if they knew, and you’re not financially or emotionally ready for that step. You feel proud of yourself for advocating for your needs to your long-time physician, and excited about the resources they’ve included in your after visit summary and the referrals they’d made to gender-confirming specialists.

When you get home, you are confronted with a terrible reality that your doctor’s notes, orders, and recommendations are immediately viewable to anybody with your MyChart login – your parents knew the second your doctor signed the note. They received the notification, logged on as your guardians, and you have effectively been “outed” by the physician who took and oath to care for you and who you trusted implicitly.
 

How the Cures Act is affecting patients

While these examples may sound extreme, they are becoming more and more commonplace thanks to a recently enacted 21st Century Cures Act. The act was originally written to improve communication between physicians and patients. Part of the act stipulates that nearly all medical information – from notes to biopsies to lab results – must be available within 24 hours, published to a patient portal and a notification be sent to the patient by phone.

Oftentimes, this occurs before the ordering physician has even seen the results, much less interpreted them and made a plan for the patient. What happens now, not long after its enactment date, when it has become clear that the Cures Act is causing extreme harm to our patients?

Take, for example, the real example of a physician whose patient found out about her own intrauterine fetal demise by way of an EMR text message alert of “new imaging results!” sent directly to her phone. Or a physician colleague who witnessed firsthand the intrusive unhelpfulness of the Cures Act when she was informed via patient portal releasing her imaging information that she had a large, possibly malignant breast mass. “No phone call,” she said. “No human being for questions or comfort. Just a notification on my phone.”

The stories about the impact of the Cures Act across the medical community are an endless stream of anxiety, hurt, and broken trust. The relationship between a physician and a patient should be sacred, bolstered by communication and mutual respect.

In many ways, the new act feels like a third party to the patient-physician relationship – a digital imposter, oftentimes blurting out personal and life-altering medical information without any of the finesse, context, and perspective of an experienced physician.
 

Breaking ‘bad news’ to a patient

In training, some residents are taught how to “break bad news” to a patient. Some good practices for doing this are to have information available for the patient, provide emotional support, have a plan for their next steps already formulated, and call the appropriate specialist ahead of time if you can.

Above all, it’s most important to let the patient be the one to direct their own care. Give them time to ask questions and answer them honestly and clearly. Ask them how much they want to know and help them to understand the complex change in their usual state of health.

Now, unless physicians are keeping a very close eye on their inbox, results are slipping out to patients in a void. The bad news conversations aren’t happening at all, or if they are, they’re happening at 8 p.m. on a phone call after an exhausted physician ends their shift but has to slog through their results bin, calling all the patients who shouldn’t have to find out their results in solitude.

Reaching out to these patients immediately is an honorable, kind thing to, but for a physician, knowing they need to beat the patient to opening an email creates anxiety. Plus, making these calls at whatever hour the results are released to a patient is another burden added to doctors’ already-full plates.
 

Interpreting results

None of us want to harm our patients. All of us want to be there for them. But this act stands in the way of delivering quality, humanizing medical care.

It is true that patients have a right to access their own medical information. It is also true that waiting anxiously on results can cause undue harm to a patient. But the across-the-board, breakneck speed of information release mandated in this act causes irreparable harm not only to patients, but to the patient-physician relationship.

No patient should find out their cancer recurred while checking their emails at their desk. No patient should first learn of a life-altering diagnosis by way of scrolling through their smartphone in bed. The role of a physician is more than just a healer – we should also be educators, interpreters, partners and, first and foremost, advocates for our patients’ needs.

Our patients are depending on us to stand up and speak out about necessary changes to this act. Result releases should be delayed until they are viewed by a physician. Our patients deserve the dignity and opportunity of a conversation with their medical provider about their test results, and physicians deserve the chance to interpret results and frame the conversation in a way which is conducive to patient understanding and healing.

Or is it? You’re not sure. The biopsy sure sounds bad. But you’re an English teacher, not a doctor, and you spend the rest of the night Googling words like “tubulovillous” and “high-grade dysplasia.” You sit awake, terrified in front of the computer screen desperately trying to make sense of the possibly life-changing results. You wish you knew someone who could help you understand; you consider calling your doctor’s emergency line, or your cousin who is an ophthalmologist – anybody who can help you make sense of the results.

Or imagine another scenario: you’re a trans teen who has asked your doctor to refer to you by your preferred pronouns. You’re still presenting as your birth sex, in part because your family would disown you if they knew, and you’re not financially or emotionally ready for that step. You feel proud of yourself for advocating for your needs to your long-time physician, and excited about the resources they’ve included in your after visit summary and the referrals they’d made to gender-confirming specialists.

When you get home, you are confronted with a terrible reality that your doctor’s notes, orders, and recommendations are immediately viewable to anybody with your MyChart login – your parents knew the second your doctor signed the note. They received the notification, logged on as your guardians, and you have effectively been “outed” by the physician who took and oath to care for you and who you trusted implicitly.
 

How the Cures Act is affecting patients

While these examples may sound extreme, they are becoming more and more commonplace thanks to a recently enacted 21st Century Cures Act. The act was originally written to improve communication between physicians and patients. Part of the act stipulates that nearly all medical information – from notes to biopsies to lab results – must be available within 24 hours, published to a patient portal and a notification be sent to the patient by phone.

Oftentimes, this occurs before the ordering physician has even seen the results, much less interpreted them and made a plan for the patient. What happens now, not long after its enactment date, when it has become clear that the Cures Act is causing extreme harm to our patients?

Take, for example, the real example of a physician whose patient found out about her own intrauterine fetal demise by way of an EMR text message alert of “new imaging results!” sent directly to her phone. Or a physician colleague who witnessed firsthand the intrusive unhelpfulness of the Cures Act when she was informed via patient portal releasing her imaging information that she had a large, possibly malignant breast mass. “No phone call,” she said. “No human being for questions or comfort. Just a notification on my phone.”

The stories about the impact of the Cures Act across the medical community are an endless stream of anxiety, hurt, and broken trust. The relationship between a physician and a patient should be sacred, bolstered by communication and mutual respect.

In many ways, the new act feels like a third party to the patient-physician relationship – a digital imposter, oftentimes blurting out personal and life-altering medical information without any of the finesse, context, and perspective of an experienced physician.
 

Breaking ‘bad news’ to a patient

In training, some residents are taught how to “break bad news” to a patient. Some good practices for doing this are to have information available for the patient, provide emotional support, have a plan for their next steps already formulated, and call the appropriate specialist ahead of time if you can.

Above all, it’s most important to let the patient be the one to direct their own care. Give them time to ask questions and answer them honestly and clearly. Ask them how much they want to know and help them to understand the complex change in their usual state of health.

Now, unless physicians are keeping a very close eye on their inbox, results are slipping out to patients in a void. The bad news conversations aren’t happening at all, or if they are, they’re happening at 8 p.m. on a phone call after an exhausted physician ends their shift but has to slog through their results bin, calling all the patients who shouldn’t have to find out their results in solitude.

Reaching out to these patients immediately is an honorable, kind thing to, but for a physician, knowing they need to beat the patient to opening an email creates anxiety. Plus, making these calls at whatever hour the results are released to a patient is another burden added to doctors’ already-full plates.
 

Interpreting results

None of us want to harm our patients. All of us want to be there for them. But this act stands in the way of delivering quality, humanizing medical care.

It is true that patients have a right to access their own medical information. It is also true that waiting anxiously on results can cause undue harm to a patient. But the across-the-board, breakneck speed of information release mandated in this act causes irreparable harm not only to patients, but to the patient-physician relationship.

No patient should find out their cancer recurred while checking their emails at their desk. No patient should first learn of a life-altering diagnosis by way of scrolling through their smartphone in bed. The role of a physician is more than just a healer – we should also be educators, interpreters, partners and, first and foremost, advocates for our patients’ needs.

Our patients are depending on us to stand up and speak out about necessary changes to this act. Result releases should be delayed until they are viewed by a physician. Our patients deserve the dignity and opportunity of a conversation with their medical provider about their test results, and physicians deserve the chance to interpret results and frame the conversation in a way which is conducive to patient understanding and healing.

Pyoderma gangrenosum (PG), a rare and painful ulcerative skin disorder, requires special care because “it’s a challenging diagnosis to make” and is frequently linked to serious comorbid conditions, a dermatologist told colleagues.

PG is also challenging to manage, said Jeffrey Callen, MD, professor and chief of the division of dermatology at the University of Louisville (Ky.), who spoke at the Inaugural Symposium for Inflammatory Skin Disease. “There are multiple treatments, but few have a high level of evidence to document their efficacy.”

PG is a neutrophilic dermatosis that usually occurs with a small lesion, often pustular, that spreads, and is a diagnosis of exclusion. “There’s no way you can possibly exclude everything, but the major things that have to be excluded are infection and malignancies,” he said. “Doing a good history and physical examination is critical, and a biopsy should be done in the vast majority of patients.”

Cultures and routine labs should be obtained, said Dr. Callen, highlighting tests that measure immunofixation (IFE), antineutrophil cytoplasmic antibodies (ANCE), anticardiolipin antibody (aCL), and lupus anticoagulant (LA).

Bowel and bone marrow tests may be appropriate in some patients, he said, noting that about half of PG cases are linked to comorbid conditions such as inflammatory bowel disease (IBD), arthritis, and hematologic diseases.

Dr. Callen also made the following points about making the diagnosis:

• Several clinical variants exist: classic, peristomal, and atypical.
• Pathergy – hyperreactivity of skin to injury – occurs in about a third of patients.
• Neutrophilic infiltrates may occur in other organs.
• Numerous drugs, including isotretinoin, can cause PG.
• PG may be misdiagnosed as necrotizing fasciitis.
• Several diagnostic frameworks exist: the Su Criteria, the PARACELCUS Score, and the Delphi Consensus Criteria. The Delphi criteria identified the highest percentage of cases (89%) in a study comparing the three, published in 2020. The frameworks “are helpful in the clinic, but they are not to be used as criteria for diagnosis. They’re really for classification,” Dr. Callen said.

Once the diagnosis has been made, he said, focus on healing the wound, which he said “can be done as any other wound would be healed,” and calming the inflammation.

“Patients who have mild disease might be treated with lower doses of prednisone, topical medications, or intralesional injections,” he said. “Corticosteroids are never wrong in the beginning.” Some patients may have genetic abnormalities related to PG, he added, and medications that target them may be appropriate.

Antibiotics and biologic agents, particularly TNF-alpha inhibitors, are possible treatments, Dr. Callen said. He highlighted a 2018 systematic review that evaluated treatments and found the most evidence supported systemic corticosteroids, cyclosporine, and TNF-alpha inhibitors. However, the quality of studies was limited, and the authors noted that the lesions frequently failed to respond or recurred.

When appropriate, surgery can be performed, he said.

Dr. Callen reported no relevant disclosures.
