MADAM, Autoantibodies in pemphigus target preferentially desmoglein 1 (Dsg1) and Dsg3, and rarely desmocollins 1-3 (Dsc1-3). Pemphigus herpetiformis (PH) is one of pemphigus subtypes and characterized by pruritic annular erythemas with vesicles in the periphery, rarity of mucosal involvement and…

Serological diagnosis of autoimmune bullous skin diseases: Prospective comparison of the BIOCHIP mosaic-based indirect immunofluorescence technique with the conventional multi-step single test strategy
Background Various antigen-specific immunoassays are available for the serological diagnosis of autoimmune bullous diseases. However, a spectrum of different tissue-based and monovalent antigen-specific assays is required to establish the diagnosis. BIOCHIP mosaics consisting of different antigen substrates allow polyvalent immunofluorescence…
Childhood pemphigus vulgaris successfully treated with rituximab
Pemphigus is a potentially fatal autoimmune epidermal bullous disorder. Rituximab is a novel therapy for the treatment of refractory pemphigus. However, there is limited clinical data on safety and efficacy of rituximab in pediatric age group. Herein, we report an…
Efficacy of low-dose rituximab in a refractory acquired factor VIII inhibitor case secondary to pemphigus.
Acquired factor VIII (FVIII) inhibitor induces a bleeding disorder caused by specific antibodies to FVIII. The cause of approximately one fifth of cases can be attributed to autoimmune disorders, such as pemphigus. Here, we describe a case of refractory acquired…
Twins with Neonatal Pemphigus Vulgaris Born to a Mother with Pemphigus Vulgaris: A Case Report
Dichorionic diamniotic twins were born at 37 weeks of gestation by cesarean section to a 34-year-old primigravid Japanese woman because the first twin was in breech presentation. The mother had been diagnosed with pemphigus vulgaris prior to her pregnancy. In addition…
Lack of relationship between blood groups and clinical outcome (body surface area affected) in patients with pemphigus vulgaris
Associations between blood groups and several diseases are observed in the literature. Some of these have scientific support suggesting a rationale, statistical relation. The association between ABO groups with several malignancies, hypercholesterolemia, thrombosis, myocardial infarction, duodenal ulcer, infections, and autoimmune…
Brazilian blood donation eligibility criteria for dermatologic patients.
A focused and commented review on the impact of dermatologic diseases and interventions in the solidary act of donating blood is presented to dermatologists to better advise their patients. This is a review of current Brazilian technical regulations on hemotherapeutic…
Ultrastructure of acantholysis in pemphigus foliaceus reexamined from the current perspective.
Background Pemphigus foliaceus (PF) is a chronic cutaneous autoimmune blistering disease that is characterized by superficial blistering of the skin, and according to the current perspective is caused by autoantibodies directed against desmoglein 1 (Dsg1). Objectives To examine early acantholysis…
Is there an emergent need to modify the Desmoglein compensation theory in pemphigus on the basis of ELISA data and alternative pathogenic mechanisms ?
We read with interest the study by Koga H et al1 and we believe that in light of recent observations including our data (Table 1) the “desmoglein compensation theory” as a explanation for localization of blisters should be revisited 2,3,4.…
Enrichment of total serum IgG4 in pemphigus patients.
Background: Pemphigus vulgaris (PV) and pemphigus foliaceus (PF) are potentially fatal blistering diseases caused by autoantibodies targeting desmoglein adhesion proteins. Previous studies have shown an IgG4>IgG1 predominance of anti-desmoglein antibodies in pemphigus; however, no studies have examined total serum IgG4…
