HLA-DQ B1*0201 and A1*0102 Alleles Are Not Responsible for Antituberculosis Drug-Induced Hepatotoxicity Risk in Spanish Population

چکیده
AIMS To evaluate the role of human leukocyte antigen (HLA) class II DQB1*0201 and DQA1*0102 in the risk of antituberculosis drug (ATD)-induced hepatotoxicity (ATDH) in a cohort of tuberculosis patients of Caucasian origin from Spain. METHODS Matched case-control study including active tuberculosis (TB) patients from Spain (Caucasian) treated with first-line ATD (Isoniazid, Rifampin, and Pyrazinamide). Presence or absence of HLA class II DQB1*0201 and DQA1*0102 alleles were compared between cases and controls. RESULTS We included 110 TB patients, 55 ATDH cases, and 55 sex-matched controls. The analysis of the presence of HLA-DQB1*0201 and HLA-DQA*0102 did not show significative differences between both groups [presence of HLA-DQB1*0201 53.6% of the cases vs. 45.4% of the controls, OR: 1.63 95% CI (0.62-4.52) p = 0.38; presence of HLA-DQA*0102 7.5% of cases vs. 20% of controls, OR: 0.36 95% CI (0.08-1.23) p = 0.12]. After multivariate logistic regression analysis including in the model, other potential risk factors of hepatotoxicity HLA class II DQB1*0201 and DQA1*0102 alleles were not found significantly associated with the risk of development ATDH. We could not demonstrate an association between HLA-DQA1*0102 and HLA-DQB1*0201 with the risk of ATDH in this Caucasian population of Spanish origin.

CONTEXT Human leukocyte antigen (HLA) DQ haplotypes have the strongest genetic association with type 1 diabetes (T1DM) risk. OBJECTIVE The objective of the study was to analyze whether HLA DQ alleles influence the development of antiislet autoantibodies, the progression to T1DM among autoantibody-positive relatives, or both. DESIGN The Diabetes Prevention Trial-1 screened more than 90,000 n...
متن کاملUse of complete eluted peptide sequence data from HLA-DR and -DQ molecules to predict T cell epitopes, and the influence of the nonbinding terminal regions of ligands in epitope selection.
In diseases with a strong association with an HLA haplotype, identification of relevant T cell epitopes may allow alteration of the pathologic process. In this report we use a reverse immunogenetic approach to predict possible HLA class II-restricted T cell epitopes by using complete pool sequencing data. Data from HLA-DR2(B1*1501), -DR3(B1*0301), -DQ2(A1*0501, B1*0201), and -DQ8(A1*0301, B1*03...
