Background/aim: In this study, we aimed to investigate different types of celiac antibodies in psoriasis patients and see if the presence was associated with other variables. Materials methods: We included plaque who were followed up our dermatology clinic between February 2019 2021 added a healthy control group for comparison. The studied serum antitissue transglutaminase (tTG)-IgA, tTG-IgG, a...

background: iga nephropathy, a prevalent disease in asia, is considered the main cause of end stage renal disease among primary glomerular disease. objective: to determine the frequency of different clinical, histopathological and immunofluorescent characteristics of iga nephropathy. methods: renal biopsies of 376 patients were received for immunofluorescent and for histopathological studies. b...

Passive hemagglutination assays (PHA) may be used to detect IgA antibodies to confirm clinical diagnoses of suspected IgA anaphylactic transfusion reactions. Passive hemagglutination inhibition assays (PHIA) may be used to identify IgA-deficient blood donors whose plasma-containing components are transfused to prevent anaphylactic transfusion reactions in prospective recipients at risk because ...

Background: The study of antiphospholipid antibodies (aPL), not included in the Sydney diagnostic criteria, syndrome (APS) and systemic lupus erythematosus (SLE) is poorly understood. Objectives: To determine frequency detection IgA-aCL IgA-aβ2GP1 IgG to β2GP1 domain 1 (IgG-aβ2GP1-D1) patients with APS without SLE. Methods: ELISA chemiluminescence assays (CMA) were used test 63 sera patients: 2...

Immunoglobulin A (IgA) is the primary immune response induced in the intestine by rotavirus infection, but vaccination with virus-like particles induces predominantly IgG, not IgA. To definitively assess the role of IgA in protection from rotavirus infection, IgA knockout mice, which are devoid of serum and secretory IgA, were infected and then rechallenged with murine rotavirus at either 6 wee...

Because abnormalities of mucosal immunity have been suggested in human IgA nephropathy, we examined the involvement of mucosal immunity in IgA deposition to the kidney in hyper IgA (HIGA) mice, which was established as a mouse model for human IgA nephropathy with hyperserum IgA. The number of surface IgA+B220- lymphocytes in the intestinal lamina propria (LP) of HIGA mice increased 2.7-fold at ...
