The FS Antigen – Desmoglein 1. It appears most commonly between the ages of 50-60 years. In most cases, the autoantibodies are immunoglobulin type G (IgG) but in IgA pemphigus, the autoantibodies are type A (IgA). The result is the surface keratinocytes separate from each other, and are replaced by fluid: the blister. The endemic form is thought to have an environmental cause. This is an autoimmune bullous dermatosis, known locally as fogo selvagem (wildfire). Typically, pemphigus vulgaris and nonendemic pemphigus foliaceous typically occur in adults between 40-60 years old. Others have suggested viral infections, certain food compounds, ionizing radiation, and pesticides may trigger or worsen the disease. Classical pemphigus consists of two major subtypes, pemphigus vulgaris (PV) and pemphigus foliaceus (PF). Klinik. In pemphigus vulgaris, autoantibodies are directed to desmoglein 3 and in pemphigus foliaceus to desmoglein 1. The mouth is the most common location of mucosal lesions, and often is the first area the disease manifests. Mögliche Ursachen. Blistering may be accompanied by severe pain, itching, burning, and stinging. Home Certain types will target desmoglein 1 in superficial tissues (causing pemphigus foliaceus), while others will target desmoglein 3 in deeper tissues (causing pemphigus vulgaris). Why autoantibodies attack cell adhesion is still intensively debated. Pemphigus foliaceus is mediated by IgG autoantibody against desmoglein 1 (Dsg1), a transmembrane glycoprotein cadherin important to cell–cell adhesion and signaling between keratinocytes (1). N Engl J Med 343: 23-30; Warren SJ et al. Because the blister is very close to the surface of the skin, the blisters rupture easily. 2012 Mar 8. Entwicklung schlaffer Blasen, Erosionen und Krusten .

In pemphigus foliaceus, autoantibodies bind to a protein called desmoglein-1, which is found in desmosomes in the keratinocytes near the top of the epidermis. Pemphigus vulgaris is the most common form of pemphigus and occurs all over the world. These desmoglein gene family members are located in a cluster on chromosome 18. Pemphigus foliaceus (both endemic and sporadic) is caused by autoantibodies against desmoglein 1. Warren SJ et al. Immunoelectron microscopy has localized both pemphigus vulgaris and pemphigus foliaceus antigens to the desmosomes, the most prominent cell–cell adhesion junctions in stratified squamous epithelia. » Indian Pediatr. Several reasons have been proposed, including events that cause cell separation and damage to adhesive molecule function. Bei Patienten mit Pemphigus vulgaris, die an Haut- und Schleimhautveränderungen leiden, wird zusätzlich zu Desmoglein 3 auch Desmoglein 1 erkannt. Medikamente: Gelegentlich löst auch ein Medikament die Bildung von Autoantikörpern aus. Some studies indicate women in Tunisia are four times more likely to have pemphigus foliaceous than men.

Pemphigus erythematosus is a variant that just affects the face and overlaps with lupus erythematosus. The most common form of pemphigus is pemphigus vulgaris; however, in some areas of the world, pemphigus foliaceus is more prevalent. It takes, on average, five doctors 10 months to make a diagnosis of PV. In women with cervical involvement, pemphigus vulgaris may be mistaken for cervical dysplasia during Papanicolaou (Pap) smears. Desmosomes are cell-cell junctions between epithelial, myocardial and certain other cell types. Warren et al. Histopathologie. The blistering in pemphigus happens because of an immune response resulting in autoantibodies attacking the “glue” that holds mucous membranes or skin cells together. Patients with pemphigus vulgaris, a deeper form of pemphigus, have antibodies to DSG3 and sometimes DSG1 as well. Studies have found certain populations (e.g., people of Jewish ancestry, particularly Ashkenazi Jews, and inhabitants of India, Southeast Europe, and the Middle East) are at a greater risk for pemphigus vulgaris.
