Özet

A significant association between lymphomas and HLA alleles has been shown in previous studies. However, the frequency of HLA alleles and haplotypes has not been studied in Turkish lymphoma patients. We studied HLA-A, -B,-DRB1 alleles and haplotypes in 80 adult lymphomas and 360 unrelated normal subjects by PCR-SSOP method using Luminex technology. The allele frequencies of HLA-A*29, B*07, and DRB1*11 were higher in patients with Hodgkin's lymphoma (HL) compared with the controls [OR; 5.65 (95%Cl; 2.16-14.81), P = 0.001], [OR; 3.00 (95%Cl; 1.50-5.99), P = 0.003)], and [OR; 1.80 (95%CI; 1.08-3.01), P = 0.002); respectively]. In patients with non-Hodgkin's lymphoma (NHL) HLA-B*51 and DRB1*04 allele frequencies were higher than controls [OR; 2.25 (95%Cl; 1.27-4.00), P = 0.007] and [OR; 2.14 (95%CI; 120-3.78), P = 0.01]. The most frequently observed haplotypes were A*02 B*35 DRB1*11 (7.50% vs. 1.89%) in HL patients, A*0213'51 DRB1*11 (5.00% vs. 1.96%) in NHL patients, and A*02 B*35 DRB1*13 (2.19%) in the controls. We detected four haplotypes specific to NHL, five haplotypes to HL patients. Seven haplotypes were unique to controls. Our findings suggest that in HL patients, HLA-A*29, B*07, and DRB1*11 alleles, and in NHL patients, HLA-B*51 and DRB1*04 alleles might be presumptive predisposing factors. (C) 2016 Elsevier B.V.
