Bronchopulmonary dysphasia (BPD) is a complex multifactorial disease with an obvious genetic predisposition. Oxidative stress plays an important role in its pathogenesis. Glutathione S-transferases (GSTs) detoxify metabolites produced by oxidative stress within the cell and protect the cells against injury. In the present study, the hypothesis that polymorphisms in the GSTM1 and GSTT1 genes are associated with BPD in Chinese Han infants was examined. Sixty infants with BPD and 100 gestational age and birth weight-matched preterm infants without BPD were recruited. Genotyping for GSTM1 and GSTT1 was performed by multiplex polymerase chain reaction (PCR). The GSTM1 null genotype was more prevalent in BPD infants (65.0%) than in the control subjects (48.0%), which yielded higher risk towards BPD (odds ratio (OR): 2.012, 95% confidence interval (CI)=1.040-3.892, p=0.037). There was no statistically significant association of GSTT1 genotype with BPD (OR: 1.691, 95% CI=0.884-3.236, p=0.111), although the frequency of GSTT1 null genotype was higher among the BPD subjects (60.0%) than in the control patients (47.0%). GSTM1 and GSTT1 double null genotype was also higher in BPD group (38.3%) than in controls (21.0%) with a higher risk towards BPD (OR: 2.338, 95%CI=1.151-4.751, p=0.017). The results suggest that null genotypes of GSTM1 and GSTT1 genes may contribute to the development of BPD in our Chinese Han population.
