Selective immunoglobulin A (IgA) deficiency is the most common primary immunodeficiency in humans and may be associated with chronic gastrointestinal disease. This observation has led to the suggestion that the high susceptibility of German shepherd dogs (GSD) to chronic enteropathies is related to a deficiency in mucosal IgA production. Relative deficiencies of IgA has been reported in the ser...

BACKGROUND An association of selective IgA (immunoglobulin A) deficiency in individuals with autism has been previously described. The objective of this study was to examine the incidence of autism spectrum disorders (ASD) in children and siblings of selective IgA deficient patients. OBJECTIVE to assess the likelihood of parents with the most common type of primary immunodeficiency (selective...

Anaphylactic transfusion reactions are acute, potentially life-threatening events with generalized signs and symptoms. Usually IgE mediated they may also result from antigen -antibody reaction involving non-IgE antibodies which fix complement and generate anaphylatoxins. The best documented reactions of the latter type result from presence of anti IgA antibodies in IgA deficient patients who re...

AIM The association between celiac disease and infertility is controversial in the literature. The aim of this study was to determine the prevalence of celiac disease among the couples with unexplained infertility. MATERIAL & METHODS Serum samples from 100 Iranian couples with unexplained infertility were evaluated for celiac disease by tissue transglutaminase antibody (tTGA). Two hundred cou...

BACKGROUND Immunoglobulin replacement therapy is an effective route of management for both infections and non-infectious complications in predominantly antibody deficiency (PAD). Trace levels of IgA (ranged from 0.4 to 2500 mg/ml), which exist in all immunoglobulin products, could lead to an increased susceptibility for adverse reactions in PAD patients. Furthermore, the exact mechanism which s...
