RESUMEN
Importance: First-line systemic therapy for morphea includes methotrexate with or without systemic corticosteroids. When this regimen is ineffective, not tolerated, or contraindicated, a trial of mycophenolate mofetil (MMF) or mycophenolic acid (MPA)-referred to herein as mycophenolate-is recommended; however, evidence to support this recommendation remains weak. Objective: To evaluate the effectiveness and tolerability of mycophenolate for the treatment of morphea. Design, Setting, and Participants: A retrospective cohort study was conducted from January 1, 1999, to December 31, 2018, among 77 patients with morphea from 8 institutions who were treated with mycophenolate. Main Outcomes and Measures: The primary outcome was morphea disease activity, severity, and response at 0, 3 to 6, and 9 to 12 months of mycophenolate treatment. A secondary outcome was whether mycophenolate was a well-tolerated treatment of morphea. Results: There were 61 female patients (79%) and 16 male patients (21%) in the study, with a median age at disease onset of 36 years (interquartile range, 16-53 years) and median diagnostic delay of 8 months (interquartile range, 4-14 months). Generalized morphea (37 [48%]), pansclerotic morphea (12 [16%]), and linear morphea of the trunk and/or extremities (9 [12%]) were the most common subtypes of morphea identified. Forty-one patients (53%) had an associated functional impairment, and 49 patients (64%) had severe disease. Twelve patients received initial treatment with mycophenolate as monotherapy or combination therapy and 65 patients received mycophenolate after prior treatment was ineffective (50 of 65 [77%]) or poorly tolerated (21 of 65 [32%]). Treatments prior to mycophenolate included methotrexate (48 of 65 [74%]), systemic corticosteroids (42 of 65 [65%]), hydroxychloroquine (20 of 65 [31%]), and/or phototherapy (14 of 65 [22%]). After 3 to 6 months of mycophenolate treatment, 66 of 73 patients had stable (n = 22) or improved (n = 44) disease. After 9 to 12 months of treatment, 47 of 54 patients had stable (n = 14) or improved (n = 33) disease. Twenty-seven patients (35%) achieved disease remission at completion of the study. Treatments received in conjunction with mycophenolate were frequent. Mycophenolate was well tolerated. Gastrointestinal adverse effects were the most common (24 [31%]); cytopenia (3 [4%]) and infection (2 [3%]) occurred less frequently. Conclusions and Relevance: This study suggests that mycophenolate is a well-tolerated and beneficial treatment of recalcitrant, severe morphea.

BACKGROUND: Several European countries recently developed international diagnostic and management guidelines for pemphigus, which have been instrumental in the standardization of pemphigus management. OBJECTIVE: We now present results from a subsequent Delphi consensus to broaden the generalizability of the recommendations. METHODS: A preliminary survey, based on the European Dermatology Forum and the European Academy of Dermatology and Venereology guidelines, was sent to a panel of international experts to determine the level of consensus. The results were discussed at the International Bullous Diseases Consensus Group in March 2016 during the annual American Academy of Dermatology conference. Following the meeting, a second survey was sent to more experts to achieve greater international consensus. RESULTS: The 39 experts participated in the first round of the Delphi survey, and 54 experts from 21 countries completed the second round. The number of statements in the survey was reduced from 175 topics in Delphi I to 24 topics in Delphi II on the basis of Delphi results and meeting discussion. LIMITATIONS: Each recommendation represents the majority opinion and therefore may not reflect all possible treatment options available. CONCLUSIONS: We present here the recommendations resulting from this Delphi process. This international consensus includes intravenous CD20 inhibitors as a first-line therapy option for moderate-to-severe pemphigus.

The first Banff vascularized composite allotransplantation meeting was held in 2007 to standardize criteria for the characterization and reporting of severity and types of rejection. As a result, the 2007 Banff VCA working classification for skin allograft pathology was formalized and now serves as the standard for diagnosis of VCA rejection. Similar to other working classification systems, strengths and limitations have been identified including the adequacy of the specimen, the definition of severity between grades, the reproducibility, the adequacy of the specimens, the types of rejection, and the integration of newer technologies such as molecular and genomic approaches. Although a relatively few number of cases have been performed and followed up to date, additional phenotypes such as antibody-mediated rejection, fibrosis, atrophy, and vascular changes are being reported and characterized based on accumulated experience in the field of VCA and parallels with other solid organs. This study aims to consider strengths and limitations of the Banff VCA working system and highlights ongoing challenges and opportunities available related to histopathology in this emerging field of transplantation.

Dermatitis herpetiformis (DH) is an autoimmune blistering skin disease in which antigen presentation in the gastrointestinal mucosa results in cutaneous IgA deposition and distinct, neutrophil-driven cutaneous lesions. Our findings suggest that the qualitatively different immune response to gluten in the intestinal mucosa of patients with DH results in minimal clinical symptoms, allowing the continued ingestion of gluten and the eventual development of DH. Our model may provide a new way to understand the pathogenesis of other skin diseases associated with gastrointestinal inflammation such as pyoderma gangrenosum or erythema nodosum, or explain association of seronegative inflammatory arthritis with inflammatory bowel disease.

The major treatment strategies for DH are gluten restriction or medical treatment with sulfones. Control of the cutaneous manifestations, but not the gastrointestinal changes, is rapid with dapsone. In addition to control of the cutaneous signs and symptoms of DH, dietary gluten restriction also induces improvement of gastrointestinal morphology and is possibly protective against the development of lymphoma.
