Methods: PAI-1 4G/5G and tPA Alu-repeat I/D genetic polymorphisms in 153 COPD subjects and 160 controls were investigated using PCR-RFLP and PCR methods, respectively. Results: 4G allele frequency was 0.62 and 0.39 for COPD and control groups, respectively. 4G allele had an estimated 2.56-fold [95% CI = 1.85-3.53] increased risk of COPD. tPA I allele frequency was 0.55 and 0.50, for COPD and control groups, respectively. I allele had an estimated 1.19-fold [95% CI = 0.87-1.62] increased risk of COPD Conclusions: PAI-1 4G/4G and 4G/5G genotypes seemed to play a key role in the pathophysiology of COPD in Turkish individuals.
