Background: Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease which is characterized by B-cell abnormality and auto-antibody generation. Since bacterial infections are the most important causes of mortality in these patients, pneumococcal vaccination is recommended for children with SLE. Objective: To investigate humoral immunity and specific-antibody formation in response to a...
background: selective antibody deficiency with normal immunoglobulins (sadni) may be identified as part of distinct primary or secondary immunodeficiency disorders. the clinical manifestations include recurrent, often severe or prolonged, upper or lower respiratory tract infections. objectives: to evaluate sadni in patients with recurrent sinopulmonary infections and its relation to igg subclas...
Background: There is a controversy about the relation between anti-hepatitis B (anti-HBs) antibody level and obesity. We designed this study to compare the vaccine efficacy in obese/overweight and non-obese cases. Methods: In this cross-sectional study, 242 obese/overweight and 85 non-obese individuals were participated. Cases were selected from a referral clinic for obesity and a referral hepa...
Introduction: Vaccination with the major surface antigen of hepatitis B virus (HBsAg) induces anti-HBs antibody production and level of 10 IU/L is considered protective. It has been shown that the level of anti-HBs antibody does wane after vaccination. The aim of this study was to evaluate the persistence of anti-HBs antibodies in healthy Iranian children 10 years after primary vaccination. Me...
Our objective was to determine whether the presence of the human leukocyte antigen HLA-DRB1 locus is associated with production of anti-cyclic citrullinated peptide antibodies (anti-CCP Abs) and to what extent they are associated with increased susceptibility to and severity of rheumatoid arthritis (RA) in Egyptian patients. Twenty-nine RA patients gave informed consent to participate in a case...
Pre-transplant (Tx) presence of HLA antibodies (HLA-Ab) especially donor specific antibodies (DSA) has been correlated with post-Tx rejection. While crossmatch (XM) is the specific method to identify DSA, logistical reasons prevent performing a prospective XM in all transplants. In such cases DSA as identified by solid-phase assay (SPA) are being used to perform a virtual crossmatch (VXM). We p...
Background: Rheumatoid arthritis (RA) is one of the most frequent autoimmune diseases in the world which affects about 1% of the worldwide population. Measurement of the Anti-CCP1 titer in these patients is one of the new tests that is available in our country. It has been shown to be more specific than Rheumatoid Factor (RF) in the diagnosis of RA (97%) in multiple studies. This test becom...
Hemolytic disease of newborn (HDN) is caused by the emergence of inappropriate antibodies against fetal blood antigens, which includes ABO and Rh blood group incompatibility. This study investigated the association between prenatal blood group antibody titer and HDN to provide a theoretic basis for clinical practice. ABO and Rh blood group of 7894 pregnant women and their husbands were screened...
Background and Aims: Hepatitis B virus (HBV) infection is a serious global health problem affects many people. Recently, because of vaccination, the incidence of HBV infection has been reduced, but in high risk population also health care students (HCS) adequate immunization is serious. The aim of this survey was to evaluate HBV immunization in the population of the paramedical students based o...
background: systemic lupus erythematosus (sle) is a chronic autoimmune disease which is characterized by b-cell abnormality and auto-antibody generation. since bacterial infections are the most important causes of mortality in these patients, pneumococcal vaccination is recommended for children with sle. objective: to investigate humoral immunity and specific-antibody formation in response to a...
