[KIR-HLA class i and pulmonary tuberculosis in the Amerindian population in Chaco, Argentina].

Introduction: The susceptibility to pulmonary tuberculosis (TB) is multifactorial, thus genetic factors such as HLA and immunoglobulins-like killer receptors (KIR) could be predisposed to the development of the disease. Aim To evaluate whether any HLA classi allele and its combination with KIR could be related to the development of TB in the Wichi Amerindian community in north-eastern Argentina.

Methods: A cohort study was conducted that included 18 families, 35 individuals affected with TB, 84 cohabiting families, and 63 controls of the same ethnic group.
