Besides anti-drug antibodies, anti-nuclear antibodies and anti-DNA antibodies are often induced in patients with rheumatoid arthritis treated with tumor necrosis factor inhibitors. We examined the association between immunogenicity, autoantibody production, and serum cytokine profiles in patients with rheumatoid arthritis treated with infliximab. Japanese patients with rheumatoid arthritis (n =...

Introduction To define the clinical features, biochemical and histological findings and outcome of three forms of autoimmune hepatitis.   Materials and Methods In a cross sectional study between November 2001 to January 2008 in Tehran and Mashhad university of medical sciences, 61 children who diagnosed as AIH (40 girls and 21 boys) have been analyzed for their clinical, serological, and histol...

Anti-Epstein-Barr virus (EBV) antibodies were tested in 11 children with chronic active EBV infection. Anti-virus capsid antigen (VCA)-IgG antibody titers ranged from 1:640 to 1:10,240. Anti-VCA-IgM antibody was consistently positive in 5 of the 11 patients; anti-VCA-IgA antibody was consistently positive in 6 of the 10 patients; anti-early antigen (EA)-IgG antibody was consistently positive in...

background: in some studies inflammatory bowel disease (ibd) and celiac disease were considered to be associated and some belive that this association may influence the prognosis of ibd. however, there is a cosiderable controversy regarding this association. therefore ,we aimed to assess the association of these two common digestive diseases and evaluate the complications of this association. m...

We report a case of an anti-nuclear antibody (ANA)-negative patient with systemic lupus erythematosus (SLE) accompanied with anti-phospholipid antibody syndrome (APS) and lupus nephritis (LN). Histological examination of placenta obtained by an artificially-induced abortion revealed multiple thromboses in the placental villi. Histology of biopsied kidney tissue revealed minimal change with depo...

background: myocardial infarction (mi) is one of the most common and serious diseases resulting from coronary artery occlusion and major reduction in blood flow. streptokinase as a thrombolytic is considered the first and most important therapeutic intervention for reperfusion following mi in most countries including iran. our previous study showed that, the prevalence of high antibody titers a...

in this study we produced and purified a high titer of specific and high affin¬ity fab fragments of anti-digoxin antibody. immunization of rabbits with a conju¬gate of the cardiac glycoside digoxin, coupled by a periodate oxidation method to the amino group of lysine in bovine serum albumin resulted in the production of this type of high titer digoxin-specific antibodies with exceptionally high...

amegakaryocytic thrombocytopenia (amt) is a rare cause of acquired thrombocytopenia. the pathogenesis and treatment of amt is not clearly known. here we demonstrate a 50-year-old man presented with the clinical manifestations of severe thrombocytopenia (7000 platelets/µl) with a marked decrease to absent of megakaryocytes in the bone marrow. the patient did not respond to intravenous immunoglob...

background: anti-sperm antibody (asa) can decrease sperm motility and, therefore, it is a cause of male infertility. the aim of this study was to evaluate the effects of varicocelectomy on anti-sperm antibody in patients with varicocele. methods: this observational study was conducted on 90 patients with varicocele at sina and imam khomeini hospitals during 2006 to 2009. all varicocelectomy can...
