BACKGROUND Patients with common variable immunodeficiency often suffer from recurrent bacterial infections. Administration of immunoglobulins is a well-established treatment to reduce the frequency and severity of these infections. However, in patients with anti-IgA antibodies or side effects to previous immunoglobulin substitution therapy, administration of immunoglobulins may lead to anaphyla...

Celiac disease has been associated with other autoimmune disorders such as autoimmune hepatitis, moreover it is known that T cell mediated immune response to dietary gluten and released cytokines are important for the entheropathy seen in celiac disease. We investigated celiac autoantibodies in patients with autoimmune hepatitis (AIH), and chronic hepatitis B (CHB).Sera from 84 patients with Au...

the diagnosis of celiac disease (cd) relies on the concordance of pathological, serological, genetic and clinical features. for this reason, the diagnosis of cd is often a challenge. seronegative celiac disease (sncd) is defined by the negativity of anti-tissue transglutaminase antibodies in the presence of a positive histology on duodenal biopsy samples, i. e. inflammatory infiltrate of intra-...

Introduction Prior to immunoprophylaxis with RhIG, 7-8 percent of Rh negative women with Rh-positive, ABO-compatible infants developed anti-Rh (D) within six months of delivery; while only one percent of Rh-negative mothers delivering ABO-incompatible babies were immunized. A significant number of women in Iran become sensitized because immunoprophylaxis is not widely practiced, resulting in he...

Chronic autoimmune thrombocytopenic purpura (AITP) is an immune-mediated, bleeding disorder in which platelets are opsonized by autoantibodies and prematurely destroyed by phagocytic cells in the reticuloendothelial system. It is classed as an organ-specific autoimmune disease primarily mediated by immunoglobulin G (IgG) autoantibodies and its etiology appears to be similar to that observed for...
