Several sporadic cases, in which direct and indirect immunofluorescence studies simultaneously detected IgG and IgA autoantibodies to keratinocyte cell surfaces, have been reported mainly under the name of IgG/IgA pemphigus. However, there have been no systematic studies for this condition. In this study, we collected 30 cases of this condition from our cohort of more than 5,000 autoimmune bullous disease cases, which were consulted for our diagnostic methods from other institutes, and summarized their clinical and immunological findings.

Pemphigus is a life threatening autoimmune epidermal blistering disease involving skin and mucous membranes. Pemphigus usually affects middle age men and women involving oral mucosa first and then spreading on the skin. It is caused by the presence of autoantibodies (IgG and less frequently by IgA) directed against desmogleins, and/or other glycoproteins that plays a critical role in cell-cell attachment. Read More

Autoimmune blistering diseases (AIBD) are a group of chronic diseases affecting the skin and mucous membranes, with different presentation, clinical course, histologic and immunopathologic findings, and different therapeutic approach. Blisters develop as a result of autoantibodies directed against distinct adhesion structures within desmosomes or within the basement membrane zone. The most common AIBD that develops in the elderly is bullous pemphigoid (previously also named "pemphigoid senilis"), but mature patients can also present with other AIBD as mucous membrane pemphigoid, epidermolysis bullosa acquisita, paraneoplastic pemphigus, pemphigus vulgaris, pemphigus foliaceus, linear IgA dermatosis, and dermatitis herpetiformis.

The involvement of the oral mucosa in patients affected by pemphigus vulgaris (PV), paraneoplastic, IgA pemphigus, and in some cases iatrogenic pemphigus is common and often a prelude to skin lesions. Intraepidermal bullae are caused by acantholysis, induced by IgG autoantibodies directed against the desmosomes and the domain of numerous keratinocytes self-antigens desmogleins (namely cadherins), thus supporting the autoimmune nature of the disease. Apoptosis may contribute to the acantholysis. Read More

Pemphigus forms a group of rare autoimmune bullous diseases that affect the skin and mucous membranes. This group has a chronic course leading to high morbidity and mortality. It is characterized by the production of pathogenic autoantibodies directed against different proteins of the desmosome, leading histologically to intraepidermal cleavage, and clinically to vesicles and erosions on the epithelium of the mucous membranes and/or the skin.

Pemphigus herpetiformis is an autoimmune bullous disease, that combines clinical features of dermatitis herpetiformis and linear IgA bullous dermatosis and immunological characteristics of pemphigus, which makes this disease peculiar and this diagnosis rarely suspected in the first evaluation of the patient. The reported case is of a patient with clinically bullous disease similar to dermatitis herpetiformis, whose multiple biopsies were inconclusive, and only after direct immunofluorescence with a pemphigus pattern (intraepidermal intercellular pattern) the confirmation of the diagnosis was possible.

Background: We identified a new variant of endemic pemphigus foliaceus in El Bagre, Colombia, South America, which we term El Bagre-EPF, and observed reactivity to arrector pili muscle (APM), thus we tested for autoimmunity to APM.
Methods: We took skin biopsies from 30 patients with El Bagre-EPF and 30 healthy controls (HCs) matched by age, sex and occupation, who were all from the endemic area, and tested these using direct immunofluorescence (DIF), confocal microscopy, immunohistochemistry and immunoblotting (IB).
Results: Of the 30 patients with El Bagre-EPF, 27 had autoantibodies to APM that colocalized with commercial antibodies to myocardium-enriched zonula occludens-1-associated protein (MYZAP), desmoplakin (DP)1 and DP2, plakophilin 4, and Armadillo repeat gene deleted in velo-cardio-facial syndrome (ARVCF) (P < 0.

Autoantibodies against the 3 desmocollin (Dsc; Dsc1-Dsc3) isoforms have been described in different pemphigus variants. Here, we developed state-of-the-art detection systems for serum anti-Dsc1, Dsc2 and Dsc1 IgG and IgA. These assays were applied in 5 different cohorts including pemphigus vulgaris (PV) patients with compatible direct immunofluorescence (IF) microscopy but no reactivity against desmogleins 1 and 3 (n = 24) and sera from patients with autoimmune blistering diseases with positive direct IF microscopy taken at the time of diagnosis (n = 749).

Immunofluorescence (IF) tests have redefined our understanding of many immune-mediated skin diseases, especially autoimmune blistering diseases (AIBDs). Nomenclature of certain AIBDs (for example, linear IgA diseases and IgA pemphigus) has been done based solely on the finding of tissue-bound immunoreactants as detected by IF tests. Direct and indirect are the two major types of IF tests; they are not only useful in the diagnosis but also guide the clinician in the treatment at least in certain AIBDs, as the titer of circulating antibodies as detected by IF reflects the disease activity.

Background: Serologic diagnosis of autoimmune blistering disease (AIBD) usually follows a sophisticated multistep algorithm.
Objective: We sought validation of a multivariant enzyme-linked immunosorbent assay (ELISA) in the routine diagnosis of AIBD.
Methods: The multivariant ELISA comprising 6 recombinant immunodominant forms of major AIBD target antigens, ie, desmoglein 1, desmoglein 3, envoplakin, BP180, BP230, and type VII collagen was applied in: (1) a cohort of well-characterized AIBD (n = 173) and control sera (n = 130), (2) a prospective multicenter study with 204 sera from patients with newly diagnosed AIBD with positive direct immunofluorescence microscopy, and (3) a prospective monocenter study with 292 consecutive sera from patients with clinical suspicion of AIBD in comparison with the conventional multistep diagnostic algorithm.

The identification of these syndromes provides information about the underlying tumor, systemic symptoms, and debilitating complications. The recognition of these syndromes is particularly helpful in cases of skin lesions presenting as the first sign of the malignancy, and the underlying malignancy can be treated in a timely manner.

Generalized pustular psoriasis, or psoriasis of von Zumbusch, is an acute and severe clinical form of psoriasis, which usually occurs in patients with psoriasis undergoing aggravating factors. In this work, we report the case of a female patient, 70 years old, who developed generalized pustular psoriasis symptoms while reducing the dose of oral corticosteroids, improperly introduced for the treatment of alleged acute generalized exanthematous pustulosis. The differential diagnosis of generalized pustular psoriasis should be made with other pustular dermatoses, such as subcorneal pustulosis, IgA pemphigus and especially with acute generalized exanthematous pustulosis.

Background And Objectives: While most previous surveys on the clinico-epidemiological features of autoimmune bullous diseases (AIBDs) have predominantly focused on a single disease entity or just one disease group, there have been only few studies examining the incidence of various AIBDs. In the present study, we set out to determine the spectrum of AIBDs, to estimate the incidence of the most common AIBDs, and to examine their temporal trends in Central Serbia over a period of 20 years.
Methods: We retrospectively recruited 1,161 new AIBD cases diagnosed in Central Serbia during the period from January 1991 to December 2010. Read More

Hintergrund Und Ziele: Die meisten früheren Arbeiten zu den klinisch-epidemiologischen Merkmalen von bullösen Autoimmunerkrankungen (AIBD) konzentrierten sich vor allem auf eine einzige Krankheitsentität oder nur eine Krankheitsgruppe; nur in wenigen Studien wurde die Inzidenz verschiedener AIBD untersucht. Bei der vorliegenden Studie war es unser Ziel, das gesamte Spektrum der AIBD zu betrachten, die Inzidenz der häufigsten AIBD zu ermitteln und die zeitlichen Trends ihres Auftretens in Zentralserbien über einen Zeitraum von 20 Jahren zu untersuchen.
Methoden: Wir rekrutierten retrospektiv 1161 AIBD-Fälle, die in Zentralserbien von Januar 1991 bis Dezember 2010 neu diagnostiziert wurden. Read More

Pemphigus refers to a group of potentially fatal blistering skin diseases that are often due to the deleterious effects of autoantibodies directed against desmosomal antigens. Although desmogleins have been mainly implicated as autoantigens in pemphigus, a steadily growing body of evidence suggests that other desmosomal proteins may be causally involved as well. Antibodies directed against desmocollin-3 have been shown to play a direct role in the pathogenesis of several types of pemphigus. Read More
