مقدمه: مالتیپل اسکلروزیس (ms) یک بیماری خودایمن است و یکی از شایعترین عوامل ناتوانی نورولوژیک، بویژه درجوانان می باشد. ms نتیجه تاثیر متقابل عوامل ژنتیکی و محیطی ناشناخته است. فراوانی برخی هاپلوتایپ های آنتی ژن لوکوسیت انسان (hla) مانندhla class ii (drb1*1501, dqa1*0102, dqb1*0602) در بیماری ms موثر شناخته شده اند. آلل hla dqa1*0102 با استعداد ابتلا بهms در برخی جمعیت ها همراهی داشته است. هدف م...
In this study the authors analysed the distribution of HLA class II alleles and the extended haplotype HLA-Cw-B-DRB1DQA1-DQB1 in Croatian patients with type I and type II psoriasis by hybridization with specific oligonucleotide probes. Type I psoriasis showed a significant association with the DRB1*0701 (p<0.00001; relative risk/RR=5.83), DQA1*0201 (p<0.00001; RR=6.12), DQB1*0201 (p=0.0006; RR=...
OBJECTIVE HLA-DRB1*03-DQB1*0201/DRB1*04-DQB1*0302 (DR3/4-DQ8) siblings who share both major histocompatibility complex (MHC) haplotypes identical-by-descent with their proband siblings have a higher risk for type 1A diabetes than DR3/4-DQ8 siblings who do not share both MHC haplotypes identical-by-descent. Our goal was to search for non-DR/DQ MHC genetic determinants that cause the additional r...
OBJECTIVE To study the influence MHC class II and TAP2 alleles exert on systemic lupus erythematosus (SLE) susceptibility and on the clinical and serological manifestations of the disease, in a cohort of Spanish patients. METHODS HLA-DR serological typing and HLA-DQA, DQB, and TAP2 DNA sequence specific oligotyping, were carried out in 85 unrelated Spanish SLE patients and 186 healthy control...
OBJECTIVE To investigate the association of HLA class II alleles with the susceptibility to sudden sensorineural hearing loss and with the results of corticosteroid treatment in the Korean population. DESIGN HLA-DRB1, -DQA1, -DQB1, and -DPB1 genotyping by the sequence-specific oligonucleotide probes method in 41 patients with sudden sensorineural hearing loss and in 206 healthy control subjec...
BACKGROUND In this study, recurrent miscarriages (RMs) are defined as loss of two or more clinically detectable pregnancies before 20 weeks of gestation. HLA has been thought to play a role in RM. However, the results of earlier studies on the role of different human leucocyte antigen (HLA) genes were conflicting and inconclusive. In the present study, we investigate HLA genes (HLA-DRA, HLA-DRB...
Gestational diabetes mellitus (GDM) is defined as glucose intolerance with onset or first recognition during pregnancy. It is associated with an increased risk of pregnancy complications. Susceptibility to GDM is partly determined by genetics and linked with type 1 diabetes-associated high risk HLA class II genes. However, the evidence for this relationship is still highly controversial. In thi...
In view of its distinct geographical location and relatively small area, Tunisia witnessed the presence of many civilizations and ethnic groups throughout history, thereby questioning the origin of present-day Tunisian population. We investigated HLA class I and class II gene profiles in Tunisians, and compared this profile with those of Mediterranean and Sub-Sahara African populations. A total...
HLA class II alleles (detected by DNA typing) were determined in 116 Caucasians with systemic sclerosis positive and negative for anticentromere autoantibodies (ACA). Significantly increased frequencies of HLA-DR5(DRw11) (P = 0.009) and the Dw13(DRB1*0403, *0407) subtypes of DR4 (probability corrected, Pc = 0.005) were seen in ACA positive patients, and HLA-DR1 and DRw8 were also increased. The...
Human leukocyte antigens class II play an important role in immune response against HCV. We investigated whether HLA class II alleles influence susceptibility to HCV infection and response to interferon therapy. HLA-DRB1 and -DQB1 loci were genotyped using PCR-SSO Luminex technology. According to our regimen, 41 (66%) of patients achieved sustained virological response to combined treatment of ...
