Autoantibodies to the desmosomal proteins desmoglein 1 and 3 cause pemphigus foliaceus and pemphigus vulgaris, which are characterised by keratinocyte dissociation (acantholysis) and intraepidermal blister formation. The passive transfer of pathogenic anti-desmoglein antibodies induces blisters in mice in vivo and the loss of keratinocyte adhesion in vitro. The pathogenetic mechanisms of acantholysis due to anti-desmoglein autoantibodies are not fully understood. However, recent studies have revealed that signalling-dependent and signalling-independent pathways are operative in the loss of cell adhesion...

BACKGROUND: Pemphigus vulgaris is a mucocutaneous blistering autoimmune disease that manifests as painful blisters or erosions on the skin and/or mucosal surfaces. IgG autoantibodies target desmoglein, playing a major role in disease pathogenesis. Genetic predisposal to pemphigus vulgaris, especially the HLA DR and DQ alleles, has been known since the 1980s. The unique constitution of the Brazilian population favors exploratory genetic studies. METHODS: The study group included 51 patients with a confirmed diagnosis of pemphigus vulgaris from a tertiary hospital in Sao Paulo city, Sao Paulo, southeast Brazil...

It is well accepted that pemphigus vulgaris (PV) is genetically linked to specific HLA class II subtypes. Environmental factors, including the role of herpes simplex virus (HSV1) in disease manifestation, have also been implicated, but in a limited number of patients and with inconsistent results. To clarify an association between HSV1 and PV in a large data set, including a stratification by dynamic and static clinical parameters, including disease activity, therapy status, HLA association, and gender. Serum HSV1 IgG levels from PV patients and healthy controls were measured by ELISA...

BACKGROUND: Pemphigus is a group of autoimmune blistering diseases of which the major forms are pemphigus foliaceus (PF) and vulgaris (PV). In Brazil, PF occurs in an endemic form also known as fogo selvagem. The main autoantibody in PF is against desmoglein 1 (DSG1), while in PV the main antibody is anti-desmoglein 3 (DSG3), but often anti-DSG1 is also present. The aim of the present study was to analyze the levels of anti-DSG1 and antiDSG3 autoantibodies in Brazilian PF and PV patients, considering different stages of the disease for PF patients and comparing these levels to those of healthy individuals living in and outside the endemic regions...

Strongyloidiasis is a frequent misdiagnosed parasitic infection in the world that caused by Strongyloides stercoralis. In Iran, the disease is predominantly reported from warm and humid climate provinces. The patient was a 54-yr-old man, originated from Khuzestan Province with a history of pemphigus and diabetes that was treated with high-dose of corticosteroid drugs before admission in a non-private hospital in Shiraz, Iran in 2014. After different primary diagnosis and administrating of several drugs, endoscopy and histopatholgical biopsy revealed a massive S...

BACKGROUND: Acetylcholine receptor (AchR) antibody levels significantly correlate with disease severity at initial pemphigus diagnosis and during follow-up. However, it is not clear if they are just an epiphenomenon or a potential trigger of the known pathogenic process in pemphigus vulgaris. OBJECTIVE: We sought to assess the changes in anti-muscarinic (M3) AchR and anti-desmoglein (Dsg) antibody titers with therapy. METHODS: This was a hospital-based cohort study involving 45 patients with active pemphigus...

Pregnancy is rare among patients affected by pemphigus, especially in European countries, mainly because of older patients, lower fertility rates and possible teratogenic risk.(1) Avoidance of immunosuppressive medications during pregnancy has been recommended, but inadequate treatment of pemphigus may increase morbidity and mortality.(2) Corticosteroids remain the first-line agent for treatment of pemphigus in pregnancy when low dosages are sufficient for disease control; however, prednisone and its metabolites crosses the placenta barrier, and high levels in the serum have been associated with adverse fetal outcomes...

Irene Russo, Andrea Saponeri, Anna Michelotto, Mauro Alaibac
Pemphigus vulgaris (PV) is a rare autoimmune intraepithelial blistering skin disease characterized by the presence of circulating autoantibodies against desmoglein 3 (DSG3) and desmoglein 1 (DSG1), resulting in loss of the normal epithelial cell-to-cell adhesion, through a process called acantholysis. In recent years, a BIOCHIP-based indirect immunofluorescence technique for the determination of anti-DSG3 and anti-DSG1 autoantibodies has been described. Even though, the use of saliva anti-DSG3 and anti-DSG1 ELISA for the diagnosis of PV has been already reported, there are no studies concerning the utilization of saliva by the BIOCHIP approach...

COMPARATIVE STUDY
Hanan Al-Saeid Al-Shenawy
Autoimmune bullous diseases are distressing and sometimes risky bullous dermatoses characterized by the presence of antibodies focused against disease-specific target antigens. Recognition of these antibodies using immunofluorescence is used to be the only sure diagnostic method after reviewing the routine histopathological section. Because of many causes that make the using of immunofluorescence difficult, we tried to evaluate the role of immunohistochemistry in diagnosis of these bullous skin diseases; 40 pemphigus cases (30 pemphigus vulgaris and 10 pemphigus foliaceus) and 37 non-pemphigus cases (35 vesiculobullous skin diseases and 2 normal skin)...

REVIEW
Isabella Jascholt, Olivia Lai, Detlef Zillikens, Michael Kasperkiewicz
Periodontitis and autoimmune bullous diseases, including pemphigus vulgaris and mucous membrane pemphigoid, are immunoinflammatory disorders leading to microbial plaque- and autoantibody-elicited tissue injury of the oral cavity, respectively. Evidence indicates that these autoimmune conditions may represent a risk factor for periodontitis, but no systematic evaluation exists to corroborate this assumption. A systematic literature review of periodontal status in pemphigus and pemphigoid was conducted. Electronic searches using PubMed from inception to July 2016 identified 10 studies meeting predetermined inclusion and exclusion criteria...

This study investigated the impact of a neonicotinoid seed-applied insecticide (Poncho Beta) and two plant densities (86,487 and 61,776 plants per hectare) on the sugarbeet root aphid (Pemphigus betae Doane), beneficial epigeal arthropods, and selected crop yield parameters in sugarbeet (Beta vulgaris L. var. vulgaris). Ground beetles and centipedes were the most commonly collected taxa during 2012 and 2013, respectively. Centipede, spider, and rove beetle activity densities were not affected by the seed-applied insecticide, whereas plant density had a marginal effect on centipede activity density during 2012...

BACKGROUND: A novel chemiluminescent enzyme immunoassay (CLEIA) was recently developed to quantify autoantibodies specific for desmogleins (Dsgs) and BP180, the target antigens of pemphigus and pemphigoid. This assay is automated and highly accurate and efficient. OBJECTIVE: To validate the use of the CLEIA for detection of autoantibodies during the clinical courses of patients with pemphigus and pemphigoid. METHODS: To define cut-off values for Dsg1, Dsg3, and BP180, we evaluated 47 serum samples from patients with pemphigus foliaceus (PF), 59 from those with pemphigus vulgaris (PV), 52 from those with bullous pemphigoid (BP), and 995 from healthy individuals...

Autoimmune blistering diseases are examples of autoantibody-mediated, organ-specific autoimmune disorders. Based on a genetic susceptibility, such as a strong HLA-class II association, as yet unknown triggering factors induce the formation of circulating and tissue-bound autoantibodies that are mainly directed against adhesion structures of the skin and mucous membranes. Compared with other autoimmune diseases, especially systemic disorders, the pathogenicity of autoimmune blistering diseases is relatively well described...

Oral biopsy of vesiculobullous diseases such as pemphigus vulgaris often raises questions due to some particularities involving this procedure. The adequate selection of the area to be biopsied defines if the final diagnosis will be reached, being the Achiles heel of the proper management of the patient. Here, the authors report a case of a woman who sought for treatment of generalized oral blisters and ulcers that caused severe pain. She had undergone a previous biopsy by other professionals that was inconclusive...

Pemphigus vulgaris (PV), pemphigus foliaceus (PF), and paraneoplastic pemphigus (PNP) are a group of rare and fatal blistering diseases involving autoantibodies that target desmosomal proteins. The pathogenesis of pemphigus involves the production of activated B-cells and IgG with stimulation by IL-4 by T-helper 2 cells. Clinically these diseases present most often with epidermal erosions of the mucosae and skin caused by rapid rupturing of flaccid bullae. These lesions correlate histologically with splits forming in the epidermis, leaving a blister roof composed of a few cell layers...

Pemphigus vulgaris is a chronic disease that is characterized by flaccid blisters and erosions, caused by immunoglobulin G autoantibodies against epidermal components. It is highly unusual in the pediatric population; it represents the 1.4 - 2.9% of the total cases. We present a case of pemphigus vulgaris in a 12 year old girl, which has implied a challenge both in its diagnosis and in its treatment.
