There is now increasing evidence for immunological changes in essential hypertension. Immunological response is determined in part by genes linked to the HLA system. It has been reported a positive association between HLA B15 and the risk for cerebral events in essential hypertensive (EH) patients. We studied the distribution of HLA antigens in 128 EH (age range, 13-85 years) and 1000 normotens...

BACKGROUND/PURPOSE Between 5% and 10% of the vaccinated population responds less well to standard vaccination schedules irrespective of hepatitis B virus (HBV) vaccination. This manuscript aims at describing possible correlation of different major histocompatibility complex (MHC) Class-I and MHC Class-II haplotype to anti-HBV humoral responsiveness following HBV vaccination. MATERIALS AND MET...

Context Human leukocyte antigens (HLAs) have an important role in the determination of susceptibility and resistance to periodontal diseases in humans, which may vary from population to population. Aims The aim of this study was to find out the association of HLA Classes I and II genes with chronic periodontitis in East Indian population. Materials and Methods In a cross-sectional study des...

Background: Hepatitis B is an important infectious disease. Since several years ago, mass vaccination against this viral infection has become as part of routine vaccination schedule of Iran. However, some healthy neonates, children and adults fail to generate a protective antibody response after vaccination. Objectives: To investigate distribution of HLA class-I and class-II antigens in healthy...

The involvement of the human leukocyte antigen (HLA) in liver graft acceptance is controversial, but the frequency of acute rejection (AR) remains high in spite of the use of the modern immunosuppressive agents. The present study was aimed at determining whether an association exists between liver recipient HLA-C polymorphism and AR development that could influence graft acceptance. Four hundre...

AIM The aim of this study was to evaluate common human leucocyte antigen (HLA) associations in patients with juvenile idiopathic arthritis (N=110), in patients with generalized aggressive periodontitis (N=50) and in patients with chronic periodontitis (N=102) in comparison to healthy controls (no periodontitis, no arthritis N=102). MATERIAL AND METHODS HLA-class I and II markers were determin...

Serum samples from 49 patients with panel reactive antibodies of greater than 15% and 17 patients who have related donor pairs were collected at the Department of Transfusion Medicine, Faculty of Medicine Siriraj Hospital. Crossmatching was performed by three methods, flow cytometry crossmatch (FCXM), the standard National Institutes of Health (NIH), and the antihuman globulin (AHG) microlympho...

background: erythropoietin (epo) was first known as a factor for red blood cell proliferation and differentiation. new studies show the effects of epo on immune system. objective: in this study, the effects of pretreatment with recombinant human erythropoietin (rhuepo) on the anti-human leukocyte antibody (anti-hla) titer were determined. methods: three groups of rats were sensitized with human...

Ulcerative colitis (UC) is a nonspecific acute and chronic inflammatory bowel disease that diffusely involves the colonic mucosa. The etiology of UC has not yet been elucidated fully. However, many studies have found that immunologic disorders may play a role in the pathogenesis of UC. In addition, due to an increased frequency of UC in families, especially an increased monozygotic compared...
