Into the Light: Afamelanotide and the Treatment of Erythropoietic Protoporphyria in the United States.

BACKGROUND: Erythropoietic protoporphyria (EPP) is a rare disease that causes disabling cutaneous photosensitivity with pain and burning sensations. In 2019, afamelanotide, an α-melanocyte-stimulating hormone analogue, was approved in the United States for treatment of EPP. In this study, patients receiving afamelanotide filled out questionnaires assessing the benefit of treatment. Outcomes measured included: return to normal activities, experience of phototoxic reactions, effect on patient confidence, and more. Patients ranked their experience on a descriptive scale ranging from "very much" to "never". RESULTS: Prior to treatment, 75% of patients indicated that EPP affected their lives "very much" or "a lot". This number fell to 11% after the 1st implant and to 0% after each subsequent implant. The number of patients that willingly ventured outside increased with each subsequent implant. CONCLUSION: The results of this study clearly show that afamelanotide treatment can dramatically and positively impact the lives of EPP patients.  Citation: Resnik SR, Targett D, Resnik BI.

Factors associated with treatment satisfaction in patients with hidradenitis suppurativa: results from the Global VOICE project.

BACKGROUND: Nearly half of patients with hidradenitis suppurativa (HS) report dissatisfaction with their treatment. However, factors related to treatment satisfaction have not been explored. OBJECTIVES: To measure associations between treatment satisfaction and clinical and treatment-related characteristics among patients with HS. METHODS: Treatment satisfaction was evaluated utilizing data from a cross-sectional global survey of patients with HS recruited from 27 institutions, mainly HS referral centres, in 14 different countries from October 2017 to July 2018. The primary outcome was patients' self-reported overall satisfaction with their current treatments for HS, rated on a five-point scale from 'very dissatisfied' to 'very satisfied'. RESULTS: The final analysis cohort comprised 1418 patients with HS, most of whom were European (55%, 780 of 1418) or North American (38%, 542 of 1418), and female (85%, 1210 of 1418). Overall, 45% (640 of 1418) of participants were either dissatisfied or very dissatisfied with their current medical treatment. In adjusted analysis, patients primarily treated by a dermatologist for HS had 1·99 [95% confidence interval (CI) 1·62-2·44, P < 0·001] times the odds of being satisfied with current treatment than participants not primarily treated by a dermatologist. Treatment with biologics was associated with higher satisfaction [odds ratio (OR) 2·36, 95% CI 1·74-3·19, P < 0·001] relative to treatment with nonbiologic systemic medications. Factors associated with lower treatment satisfaction included smoking (OR 0·78, 95% CI 0·62-0·99; active vs. never), depression (OR 0·69, 95% CI 0·54-0·87), increasing number of comorbidities (OR 0·88 per comorbidity, 95% CI 0·81-0·96) and increasing flare frequency. CONCLUSIONS: There are several factors that appear to positively influence satisfaction with treatment among patients with HS, including treatment by a dermatologist and treatment with a biologic medication. Factors that appear to lower treatment satisfaction include active smoking, depression, accumulation of comorbid conditions and increasing flare frequency. Awareness of these factors may support partnered decision making with the goal of improving treatment outcomes. What is already known about this topic? Nearly half of patients with hidradenitis suppurativa report dissatisfaction with their treatments. What does this study add? Satisfaction with treatment is increased by receiving care from a dermatologist and treatment with biologics. Satisfaction with treatment is decreased by tobacco smoking, accumulation of comorbid conditions including depression, and higher flare frequency. What are the clinical implications of this work? Awareness of the identified factors associated with poor treatment satisfaction may support partnered decision making and improve treatment outcomes.

Novel Regimen of IL-17A Inhibitor Secukinumab for the Remission of Severe Hidradenitis Suppurativa: Case Report.

Hidradenitis suppurativa (HS) is a morbid, recurrent skin condition that presents a major challenge to clinical therapy. Investigation into the pathogenesis of HS has implicated local and systemic pro-inflammatory cytokines, particularly TNF-α and IL-17A, as major determinants of disease progression and severity. This has ushered in a revolution in HS therapy with biologics targeting these cytokines. We report a case of a 36-year-old man with extensive and treatment-resistant Hurley Stage 3 HS. After undergoing numerous unsuccessful trials of topical, systemic, and biologic therapies, secukinumab therapy with 150 mg weekly injections was initiated. HS clinical response was seen after 20 weeks and was maintained for almost two years. Secukinumab 150 mg or 300 mg once weekly may be an effective and safe therapeutic option for moderate-to-severe chronic HS. J Drugs Dermatol. 2022;21(12):1358-1360. doi:10.36849/JDD.6752.

An unusual case of pyogenic granuloma-like Kaposi sarcoma.

Kaposi sarcoma (KS) is not typically included in the differential diagnosis of lesions with clinical characteristics of pyogenic granuloma. However, cases of pyogenic granuloma-like Kaposi sarcoma have been reported in the literature. This variant is extremely rare and possesses clinical and histological findings consistent with both conditions. We report an elderly, immunocompetent man with pyogenic granuloma-like Kaposi sarcoma, which was clinically consistent with a pyogenic granuloma and possessed histological findings consistent with Kaposi sarcoma and pyogenic granuloma.

Development of a hidradenitis suppurativa patient decision aid.

BACKGROUND: Patient decision aids (PDAs) are tools that facilitate informed shared decision-making between patients and health care providers. To address a previously identified need in treatment decision-making in hidradenitis suppurativa (HS), we developed an HS-PDA. METHODS: Development of the HS-PDA was based on International Patient Decision Aids Standards. Evidence was derived from the North American Clinical Management Guidelines for HS. RESULTS: Content from guidelines was transformed into patient-friendly language and reviewed by three physicians and two patient representatives. Feedback on HS-PDA content, presentation and practicality was obtained from 7 HS patients and 5 physicians. Revisions were made following thematic analysis. All patients felt the content on treatment options contained the right amount of information and 5 found it helpful to see these options contextualized to their values. Each stated they would use the HS-PDA during treatment decision-making. Three and four physicians respectively indicated the content was accurate and language was patient-friendly. LIMITATIONS: Small sample sizes may limit generalizability. CONCLUSION: This HS-PDA was developed in accordance with international standards based on current HS guidelines with input from patients and physicians. It is available online without cost.

Proceeding report of the Second Symposium on Hidradenitis Suppurativa Advances (SHSA) 2017.

The 2nd Annual Symposium on Hidradenitis Suppurativa Advances (SHSA) took place on 03-05 November 2017 in Detroit, Michigan, USA. This symposium was a joint meeting of the Hidradenitis Suppurativa Foundation (HSF Inc.) founded in the USA, and the Canadian Hidradenitis Suppurativa Foundation (CHSF). This was the second annual meeting of the SHSA with experts from different disciplines arriving from North America, Europe and Australia, in a joint aim to discuss most recent innovations, practical challenges and potential solutions to issues related in the management and care of Hidradenitis Suppurativa patients. The last session involved clinicians, patients and their families in an effort to educate them more about the disease.

Inpatient Management of Hidradenitis Suppurativa: A Delphi Consensus Study.

Inpatient hospitalization of individuals with hidradenitis suppurativa (HS) has increased. Inpatient services may not be familiar enough with this disease to understand how to manage severe HS and/or HS flares. It would be beneficial to the inpatient medical community to establish consensus recommendations on holistic inpatient care of patients with HS. A survey study was developed and distributed by Wake Forest University School of Medicine (Winston-Salem, North Carolina). A total of 26 dermatologists participated in the Delphi process, and the process was conducted in 2 rounds. Participants voted on proposal statements using a 9-point scale (1=very inappropriate; 9=very appropriate). Statements were developed using current published guidelines for management of HS and supportive care guidelines for other severe inpatient dermatologic diseases. A total of 50 statements were reviewed and voted on between the 2 rounds. Consensus was determined using the RAND/UCLA Appropriateness Method. Twenty-six dermatologists completed the first-round survey, and 24 completed the second-round survey. The 40 consensus recommendations generated through these surveys can serve as a resource for providers caring for inpatients with HS.

A case of Stevens-Johnson syndrome treated with oral cyclosporine.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) can occur at any age and are commonly caused by adverse drug events. Rapid diagnosis of SJS/TEN is imperative, followed by immediate cessation of offending agent and induction of appropriate treatment. Cyclosporine, a calcineurin inhibitor, has been reported to have a promising therapeutic effect in SJS/TEN patients with few side effects. Diagnosis of SJS/TEN in children is especially challenging as many of the symptoms mimic that of an upper respiratory infection, or other viral entities such as cocksackie A, roseola, or herpes simplex virus. We recommend initiating cyclosporine modified treatment, especially in children, upon any suspicion of SJS/TEN in a patient in order to halt the disease progression as early as possible.

Outcome Measures for the Evaluation of Treatment Response in Hidradenitis Suppurativa for Clinical Practice: A HiSTORIC Consensus Statement.

Importance: Although several clinician- and patient-reported outcome measures have been developed for trials in hidradenitis suppurativa (HS), there is currently no consensus on which measures are best suited for use in clinical practice. Identifying validated and feasible measures applicable to the practice setting has the potential to optimize treatment strategies and generate generalizable evidence that may inform treatment guidelines. Objective: To establish consensus on a core set of clinician- and patient-reported outcome measures recommended for use in clinical practice and to establish the appropriate interval within which these measures should be applied. Evidence Review: Clinician- and patient-reported HS measures and studies describing their psychometric properties were identified through literature reviews. Identified measures comprised an item reduction survey and subsequent electronic Delphi (e-Delphi) consensus rounds. In each consensus round, a summary of outcome measure components and scoring methods was provided to participants. Experts were provided with feasibility characteristics of clinician measures to aid selection. Consensus was achieved if at least 67% of respondents agreed with use of a measure in clinical practice. Findings: Among HS experts, response rates for item reduction, e-Delphi round 1, and e-Delphi round 2 surveys were 76.4% (42 of 55), 90.5% (38 of 42), and 92.9% (39 of 42), respectively; among patient research partners (PRPs), response rates were 70.8% (17 of 24), 100% (17 of 17), and 82.4% (14 of 17), respectively. The majority of experts across rounds were practicing dermatologists with 18 to 19 years of clinical experience. In the final e-Delphi round, most PRPs were female (12 [85.7%] vs 2 males [11.8%]) and aged 30 to 49 years. In the final e-Delphi round, HS experts and PRPs agreed with the use of the HS Investigator Global Assessment (28 [71.8%]) and HS Quality of Life score (13 [92.9%]), respectively. The most expert-preferred assessment interval in which to apply these measures was 3 months (27 [69.2%]). Conclusions and Relevance: An international group of HS experts and PRPs achieved consensus on a core set of HS measures suitable for use in clinical practice. Consistent use of these measures may lead to more accurate assessments of HS disease activity and life outcomes, facilitating shared treatment decision-making in the practice setting.

Prevalence and Risk Factors for Anemia in a Population With Hidradenitis Suppurativa.

BACKGROUND:  Hidradenitis suppurativa (HS) is an inflammatory disease presenting as nodules evolving into scarred plaques. HS is associated with many co-morbidities, including anemia of chronic disease, though few studies report on this association. OBJECTIVES: This study evaluated the prevalence of anemia among the HS patient population and potential associations between risk factors for HS and anemia development. METHODS: Records diagnosed HS patients in one private practice (BR) were reviewed by investigators. The 92-patient cohort was evaluated for multiple data-points and responses grouped based on age, gender, ethnicity, body mass index (BMI), smoking status, and comorbidities. Data were analyzed using STATA to perform descriptive analysis and bivariate analysis. RESULTS: The prevalence of anemia in this cohort was 41.3%. Of anemic patients, the majority were men (65.2%), African American (60.6%), and never/former smokers (48.6%). There was a significant increase in the odds of developing anemia in HS patients that are men (odds ratio (OR) 3.8) and African American (OR 3.5). CONCLUSIONS: We show that the prevalence of anemia in an HS patient population greatly surpasses that of the U.S. population (~5%). It is clear that anemia is a significant complication for HS patients. We hope that physicians can recognize the importance of screening patients with HS for anemia to medically optimize treatment for their patients.

Ethical coding.

It is ethical, legal, and proper for a dermatologist to maximize income through proper coding of patient encounters and procedures. The overzealous physician can misinterpret reimbursement requirements or receive bad advice from other physicians and cross the line from aggressive coding to coding fraud. Several of the more common problem areas are discussed.
