The study was carried out in control subjects (n=158), patients with pulmonary tuberculosis (n=154), patients with bacteriological relapse (n=50) and quiescent patients (n=50). No difference in the frequency of variant genotypes of BamH I polymorphism of CYP2D6 gene was observed between pulmonary TB patients and control subjects. A trend towards an increased frequency of 22 genotype (homozygous for infrequent allele 2) was observed in bacteriological relapse patients than quiescent patients (odds ratio, OR: 2). Similar increase was observed in male relapse patients than male quiescent patients (OR: 2.2). The present study suggests that ...
