OBJECTIVE To investigate comprehensively the relationships between Behçet's disease (BD) clinical features and HLA-B51 or HLA-B5 (HLA-B51/B5) status using meta-analyses. METHODS Relevant publications were identified by a systematic literature search. Eligible studies had to provide frequencies for one or more BD characteristics according to HLA-B51/B5 status. Pooled relative risks (RRs) were ...

background: pulmonary tuberculosis (pt) is one of the endemic diseases in iraq, and among the suggested predisposing factors are alleles of the human leukocyte antigen (hla) system. we sought to investigate the association between hla-class i (a and b) and -class ii (dr and dq) alleles in a sample of pt iraqi patients. methods: lymphocytes of 105 pt patients and 40 controls were phenotyped for ...

the human leukocyte antigen has become a key component in investigating the genetic relationships between populations. the aim of this study was to determine the genetic diversity of hla class i and ii alleles among zaboli ethnic group of south-east iran to establish a database for further investigations on ancestry and the genetic factors contributing to complex diseases in this region. unrela...

OBJECTIVE To analyze patients suffering from aplastic anemia (AA, peripheral pancytopenia and hypocellular bone marrow in the absence of dysplasia, infiltration and fibrosis) for documenting patient's baseline characteristics and association with various human leucocyte antigens. STUDY DESIGN An observational, cross-sectional study. PLACE AND DURATION OF STUDY The National Institute of Bloo...

in addition to ultrasonographic monitoring of folliculogenesis, urinary luteinizing hormone testing, luteal phase endometrial biopsy, serum antiphospholipid antibodies, etc., immunologic tests are recently being used to evaluate reproductive disorders. in this study, sharing of hla-a, b, c and dr antigens and the presence of antipaternal cytotoxic antibody (apca) was assessed using microcytotox...

Exposure to grass pollens during the pollen season, reveals in sensitive patients symptoms of allergic rhinitis, conjunctivitis and/or bronchial asthma. It is not well understood why, in some patients, only symptoms of rhinitis occur while in others similar exposure causes symptoms of asthma and rhinitis. An association study is reported here, where the possible contribution of human leucocyte ...

The aim of this study was to determine the frequency and specificity of HLA-A and B antibodies in multiparous mothers in the Malaysian population. 1,100 maternal serum samples obtained during normal childbirth were screened against a panel of 100 lymphocytes with known HLA antigen types for HLA antibodies by the complement dependent lymphocyte microcytotoxicity dye exclusion test. From the tota...

Eighteen patients who satisfied stringent criteria for the diagnosis of Buerger's disease, healthy controls, and patients with atherosclerosis were tested for various HLA antigens. The incidence of HLA-A9 and HLA-B5 was significantly greater among those with Buerger's disease. This finding supports the concept that Buerger's disease is a distinct clinicopathological condition.
