Although IgA is present in the skin of patients with dermatitis herpetiformis (DH), the relationship of that IgA to the mucosal immune response is not known. The purpose of this study was to determine if IgA antibodies directed against tissue antigens, which are present in the serum of patients with DH, are also present in the gut secretions of these patients. Serum and gut secretions from 8 patients with DH and 5 control subjects were analyzed by indirect immunofluorescence for the presence of IgA antireticulin and antiendomysium antibodies. IgA antibodies against reticulin (3 of 8 patients) and endomysium (4 of 8 patients) were found in the serum of patients with DH. IgA antibodies were also present in the gut secretions of all of these patients, but not in subjects (patients with DH and controls) that did not have serum IgA antireticulin or antiendomysium antibodies. The presence of IgA antireticulin and antiendomysium in both the serum and gut secretions of DH patients suggests that these antibodies arise as a result of the mucosal immune response and that IgA of mucosal origin can persist in the serum of patients with DH.

D009130	Muscle, Smooth	Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant.

D012155	Reticulin	A scleroprotein fibril consisting mostly of type III collagen. Reticulin fibrils are extremely thin, with a diameter of between 0.5 and 2 um. They are involved in maintaining the structural integrity in a variety of organs.

D003874	Dermatitis Herpetiformis	Rare, chronic, papulo-vesicular disease characterized by an intensely pruritic eruption consisting of various combinations of symmetrical, erythematous, papular, vesicular, or bullous lesions. The disease is strongly associated with the presence of HLA-B8 and HLA-DR3 antigens. A variety of different autoantibodies has been detected in small numbers in patients with dermatitis herpetiformis.

D004064	Digestive System	A group of organs stretching from the MOUTH to the ANUS, serving to breakdown foods, assimilate nutrients, and eliminate waste. In humans, the digestive system includes the GASTROINTESTINAL TRACT and the accessory glands (LIVER; BILIARY TRACT; PANCREAS).	Ailmentary System,Alimentary System
D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
