Guidelines of care for the management of atopic dermatitis in adults with phototherapy and systemic therapies.

BACKGROUND: For people with atopic dermatitis (AD) refractory to topical therapies, treatment with phototherapy and systemic therapies can be considered. Multiple biologic therapies and Janus kinase (JAK)inhibitors have been approved since 2014 to treat AD. These guidelines update the 2014 recommendations for management of AD with phototherapy and systemic therapies. OBJECTIVE: To provide evidence-based recommendations on the use of phototherapy and systemic therapies for AD in adults. METHODS: A multidisciplinary workgroup conducted a systematic review and applied the GRADE approach for assessing the certainty of evidence and formulating and grading recommendations. RESULTS: The workgroup developed 11 recommendations on the management of AD in adults with phototherapy and systemic agents, including biologics, oral JAK inhibitors, and other immunomodulatory medications. LIMITATIONS: Most randomized controlled trials of phototherapy and systemic therapies for AD are of short duration with subsequent extension studies, limiting comparative long-term efficacy and safety conclusions. CONCLUSIONS: We make strong recommendations for the use of dupilumab, tralokinumab, abrocitinib, baricitinib, and upadacitinib. We make conditional recommendations in favor of using phototherapy, azathioprine, cyclosporine, methotrexate, and mycophenolate, and against the use of systemic corticosteroids.

Executive summary: Guidelines of care for the management of atopic dermatitis in adults with phototherapy and systemic therapies.

BACKGROUND: The summarized guidelines update the 2014 recommendations for the management of AD with phototherapy and systemic therapies. METHODS: A multidisciplinary workgroup conducted a systematic review and applied the GRADE approach for assessing the certainty of the evidence and formulating and grading recommendations. RESULTS: The workgroup developed 11 recommendations on the management of AD in adults with phototherapy and systemic therapies, including biologics, oral Janus Kinase inhibitors, and other immunomodulatory medications. CONCLUSIONS: The evidence supported strong recommendations for the use of dupilumab, tralokinumab, abrocitinib, baricitinib, and upadacitinib and conditional recommendations in favor of using phototherapy, azathioprine, cyclosporine, methotrexate, and mycophenolate, and against the use of systemic corticosteroids.

North American clinical management guidelines for hidradenitis suppurativa: A publication from the United States and Canadian Hidradenitis Suppurativa Foundations: Part I: Diagnosis, evaluation, and the use of complementary and procedural management.

Hidradenitis suppurativa is a chronic inflammatory disorder affecting hair follicles, with profoundly negative impact on patient quality of life. Evidence informing ideal evaluation and management of patients with hidradenitis suppurativa is still sparse in many areas, but it has grown substantially in the last decade. Part I of this evidence-based guideline is presented to support health care practitioners as they select optimal management strategies, including diagnostic testing, comorbidity screening, and both complementary and procedural treatment options. Recommendations and evidence grading based on the evidence available at the time of the review are provided.

Urticaria: A comprehensive review: Treatment of chronic urticaria, special populations, and disease outcomes.

Second-generation antihistamines are considered first-line agents in the treatment of chronic urticaria because of their safety and efficacy profile. Some patients require higher doses of H1 antihistamines alone or in combination with other classes of medications, including H2 antihistamines, leukotriene receptor antagonists, or first-generation H1 antihistamines. One major therapeutic advance has been omalizumab, a humanized monoclonal anti-immunoglobulin E that was recently approved by the US Food and Drug Administration for the treatment of chronic urticaria that is unresponsive to H1 antagonists. In addition, the second article in this continuing medical education series outlines several evidence-based alternative treatments for urticaria and the differences in recommendations between 2 major consensus groups (the European Academy of Allergy and Clinical Immunology/World Allergy Organization and the American Academy of Allergy, Asthma and Immunology/American College of Allergy, Asthma and Immunology Joint Task Force).

Pediatric follicular mucinosis: presentation, histopathology, molecular genetics, treatment, and outcomes over an 11-year period at the Mayo Clinic.

Follicular mucinosis (FM) and folliculotropic mycosis fungoides (MF) are rare in children, and data regarding long-term outcomes are limited. We sought to describe clinical and histopathologic findings of children with FM with and without MF, as well as treatments administered and clinical outcomes. We conducted a retrospective chart review of patients younger than 22 years (at time of diagnosis) with a biopsy demonstrating FM who were seen in the Dermatology Department at the Mayo Clinic from September 1, 1999, to September 1, 2010. Eleven patients (six male, five female) ages 11 to 19 years at the time of diagnosis met the inclusion criteria. Follow-up data were available for 10 patients, with a mean duration of 4.9 years. The head, neck, and extremities were the most common sites of involvement, and lesions were follicular-based papules (18%), scaly alopecic patches and plaques (45%), or a combination of the two (36%). Overall, three patients were confirmed to have MF. T-cell receptor gene rearrangement demonstrated clonality in two cases and was equivocal in one case. Treatments included topical corticosteroids, topical retinoids, oral minocycline, and, in patients with MF, ultraviolet light and topical bexarotene. Lesions resolved completely in seven patients, partially in one, and not at all in two (no follow-up data on one patient). Of the three patients with MF, two had complete resolution, and one has intermittent flares. To our knowledge, no patients developed other lymphoproliferative disorders. FM in children is rare. A histopathologic diagnosis of FM does not equate to folliculotropic MF in all cases. Most patients responded to treatment with topical steroids, topical retinoids, or phototherapy. In our series of patients, the disease ran a benign course.

Combination treatments for psoriasis: a systematic review and meta-analysis.

OBJECTIVE: To summarize the current state of evidence for combination topical and systemic therapies for mild to severe psoriasis. DATA SOURCES: We performed a systematic search for all entries in PubMed, CINAHL, Cochrane Review, and EMBASE related to combination treatments for psoriasis through July 2010. STUDY SELECTION: We included randomized controlled trials that reported proportion of disease clearance or mean change in clinical severity score (or provided these data through communication with study authors) for efficacy of a combination treatment for psoriasis compared with 1 or more corresponding monotherapies. DATA EXTRACTION: Study data were extracted by 3 independent investigators, with disagreement resolved by consensus. The proportion of patients who achieved clearance, definition of clearance, means and standard deviations for baseline disease symptom score and final disease symptom score, and major design characteristics were extracted for each study. DATA SYNTHESIS: Combination treatments consisting of vitamin D derivative and corticosteroid, vitamin D derivative and UV-B, vitamin A derivative and psoralen-UV-A, vitamin A derivative and corticosteroid, vitamin A derivative and UV-B, corticosteroid and hydrocolloid occlusion dressings, UV-B and alefacept, and vitamins A and D derivatives were more effective than 1 or more monotherapies using the likelihood of clearance as the outcome. Blinding status and potency of the corticosteroid treatment used were significant sources of heterogeneity between studies. CONCLUSIONS: The results demonstrate the need for additional long-term trials with standardized outcome measures to evaluate the efficacy and adverse effects of combination therapies for psoriasis and highlight the possible effects of trial design characteristics on results.

Case of mistaken identity: bullous congenital ichthyosiform erythroderma mistaken as epidermolysis bullosa simplex.

Distinguishing clinically similar dermatologic disorders can be challenging and the differential diagnosis of a blistering eruption in the newborn period can be extensive. Several genodermatosis, such as bullous congenital ichthyosiform erythroderma (BCIE) and epidermolysis bullosa simplex (EBS), autoimmune bullous disorders, infectious diseases, sucking blisters, and bullous mastocytosis must be considered. We present a case of BCIE misdiagnosed as EBS and review characteristic clinical and histopathological features of each disorder as well as the basic approach to treatment.
