The Association of HLA-Class I and Class II with Hodgkin's Lymphoma in Iranian Patients

The Hodgkin's lymphoma disease (HD) is a commonmalignant neoplasm with germinal centre B-cell origin. It has been suggested that the HLA class I and class II regions have susceptibility effects on HD. In different ethnic groups, different HLA class I and class II alleles affect HD. As a result, there is no consensus which of the different HLA alleles confers susceptibility to HD. In this study, we aimed to ascertain the role of HLA class I and class II alleles in association with Hodgkin's lymphoma in Iranian patients. We performed a case-control genotyping study in 85 Iranian HD patients which were selected from the BoneMarrow Transplantation Department of Taleghani Hospital and 150 controls using the SSP-PCR. Our results demonstrated that the HLA-A * 68, HLA-B * 51, and HLA-DRB1 * 15 alleles were significantly more frequent in HD patients in comparison to controls (n = 0.026; OR = 6.188, p = 0.00008; OR= 2.86, p = 0.00006; OR = 5.315, resp.) and they have significant susceptibility effects onHDin Iranian population. There are reports of other populations with regard to consistency and inconsistency to our results. Further studies with large sample size or the meta-analysis are needed to explain the exact associations of HLA gene with HD.
