Background: Pemphigus is an autoimmune bullous disease (AIBD) and has two main subtypes, pemphigus vulgaris (PV) and pemphigus foliaceus (PF). For adequate interpretation and comparison of clinical studies in pemphigus, it is essential to have outcomes and outcome measurement instruments (OMIs) that are well-defined, uniform and relevant.
Objectives: To provide a comprehensive overview of previously reported outcomes and OMIs in pemphigus clinical research over the past two decades.

Background: Desmocollin-3 (DSC3) is a calcium-dependent desmosomal cadherin that plays an essential role in cell-cell adhesion. IgG antibodies (Abs) directed against the extracellular (EC) domain of DSC3 have occasionally been detected in rare types of pemphigus. Investigations into the prevalence of anti-EC-DSC3 IgG Abs and those targeting the intracellular (IC) domain of DSC3 in pemphigus vulgaris and pemphigus foliaceus sera, and their potential pathogenic activity, have yielded conflicting results.

Bullous pemphigoid is a chronic, subepidermal autoimmune blistering disease characterized by tense blisters on erythematous or normal skin that predominantly affects the older population. The disease arises from autoantibodies targeting hemidesmosomal proteins BP180 and BP230, which are crucial for dermal-epidermal adhesion. The incidence of bullous pemphigoid is increasing, attributed to an ageing population and improved diagnostic recognition.

Objective: To assess the outcome of an additional rituximab infusion at month 6 in patients with pemphigus who were in complete remission (CR) after rituximab regimen but had 1 or more predictors of relapse at month 3.
The Lübeck Institute of Experimental Dermatology celebrated its 10 Anniversary Symposium on Inflammatory Skin Diseases at the University of Lübeck, Germany, on October 17-18, 2024. This event brought together international key opinion leaders, faculty members, researchers, and clinicians to foster insightful discussions on the diagnosis, pathomechanisms, and treatment of autoimmune skin diseases, with a particular focus on pemphigus, pemphigoid diseases, and systemic sclerosis.

Trial Design: Pemphigus is a rare but life-threatening autoimmune disease requiring long-term treatment that minimizes corticosteroid (CS) exposure while providing consistent disease control. The phase 2 pemphigus study of oral, reversible, covalent Bruton tyrosine kinase inhibitor rilzabrutinib demonstrated rapid and sustained efficacy with well-tolerated safety.
Methods: Adults (aged 18-80 years) were randomized 1:1 to 400 mg rilzabrutinib (n = 65) or placebo (n = 66) twice daily (with CS ≤ 0.
