association between hla-class i and hla-class ii alleles and mycobacterium tuberculosis infection in iraqi patients from baghdad city

چکیده
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 hla-a, -b, -dr, and -dq alleles by means of the microlymphocytotoxicity test using a panel of monoclonal antisera. results: hla frequencies of b18 (16.2 vs. 2.5%; od=7.53) and dr1 (51.4 vs. 10.0%; od=9.53) alleles were significantly increased in the patients as compared with the controls, while b5 (6.7 vs. 25.0%), dr8 (1.9 vs. 17.5%), and dq3 (11.4 vs. 45.0%) alleles were significantly decreased. however, a significant corrected level was maintained for only dr1, dr8, and dq3 alleles (pc=1.9×10-5, 0.02 and 1.0×10-4, respectively). conclusion: the results confirm the predisposing and protecting roles of hla alleles in pt.

Background: The high polymorphism in the human leukocyte antigen (HLA) genes can be used as an identity of individuals to compare with other populations. This extreme polymorphism in the HLA system is accountable for the differences in alleles and haplotypes among ethnic groups, populations, and the inhabitants of many regions. Objective: To define the frequency of HLA alleles and haplotypes am...

BACKGROUND West Nile virus (WNV) infection is asymptomatic in most individuals, with a minority developing symptoms ranging from WNV fever to serious neuroinvasive disease. This study investigated the impact of host HLA on the outcome of WNV disease. METHODS A cohort of 210 non-Hispanic mostly white WNV(+) subjects from Canada and the U.S. were typed for HLA-A, B, C, DP, DQ, and DR. The study...

ULCERATIVE COLITIS AND HLA CLASS II PHENOTYPING IN IRAN
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...
