Abstract

Despite the introduction of multidrug therapy and the overall reduction of leprosy prevalence in Mexico, the disease remains endemic in certain regions of the country. A genetic basis for the immune susceptibility to Mycobacterium leprae has already been established in different populations worldwide. In this study, we investigated the possible association of the HLA‑DRB1 alleles with leprosy in a Mexican mestizo population. The results demonstrated that the HLA‑DRB1*01 allele is associated with lepromatous and dimorphic leprosy [P<0.001, odds ratio (OR)=4.6, 95% confidence interval (95% CI): 1.8‑11.4; and P=0.03, OR=6.2, 95% CI: 1.1‑31.6, respectively] and the frequency of the HLA‑DRB1*08 allele was found to be significantly lower among leprosy patients compared to controls (P=0.046, OR=2.4, 95% CI: 1‑5.8). In conclusion, although the association of the HLA‑DR locus with leprosy has been established in different populations and several studies have demonstrated significant differences in the DR alleles, this study demonstrated an association of the HLA‑DRB1*01 allele with susceptibility to lepromatous and dimorphic leprosy, as well as an association of the HLA‑DRB1*08 allele with protection against leprosy in a Mexican mestizo population.
