Small bowel transglutaminase 2-specific IgA deposits in dermatitis herpetiformis.
Dermatitis herpetiformis (DH) is an extraintestinal manifestation of coeliac disease. Untreated coeliac disease patients are known to have transglutaminase 2 (TG2)-targeted IgA deposits in the small bowel mucosa. To evaluate whether similar intestinal IgA deposits are also present in DH and whether the deposits disappear with gluten-free diet, 47 untreated and 27 treated DH patients were studie...
متن کاملMesangial IgA deposits indicate pathogenesis of anti-glomerular basement membrane disease.
Anti-glomerular basement membrane (anti-GBM) disease is characterized by crescentic glomerulonephritis with immunoglobulin G (IgG) autoantibodies to the non-collagenous (NC1) domain of α3(IV) collagen presenting along the GBM. The patient clinically manifests with rapidly progressive glomerulonephritis (RPGN) with pulmonary hemorrhage (Goodpasture...
متن کاملDermatitis herpetiformis: pathognomonic transglutaminase IgA deposits in the skin and excellent prognosis on a gluten-free diet.
Dermatitis herpetiformis (DH) is an itchy, blistering skin disease with sites of predilection at the elbows, knees and buttocks. Although DH is mostly asymptomatic, all patients exhibit small bowel villous atrophy or at least coeliac-type inflammatory changes. Deposition of immunoglobulin A (IgA) in the papillary dermis is a key diagnostic feature of DH. Epidermal transglutaminase (TG3) is the ...
متن کاملAberrantly glycosylated IgA1 in glomerular immune deposits of IgA nephropathy.
In IgA nephropathy, abnormal O-glycosylation of IgA1 molecules contributes to mesangial IgA1 deposition and the development of glomerular injury; however, direct in situ demonstration of aberrantly O-glycosylated IgA1 within glomerular immune deposits has not been reported. This study investigated the presence of abnormally glycosylated IgA1 in situ and its spatial relationship with complement ...
متن کاملDermatitis herpetiformis with fibrillar IgA deposition and unusual histologic findings
DH: dermatitis herpetiformis DIF: direct immunofluorescence INTRODUCTION Dermatitis herpetiformis (DH) is an autoimmune, subepidermal blistering disease associated with gluten sensitivity. It commonly manifests as intensely pruritic papules and vesicles on the extensor surfaces of extremities in a symmetric distribution. Classic histologic findings and data from direct immunofluorescent (DIF) s...
