摘要

Background and objective: Overexpression of matrix metalloproteinase (MMP)-1 has been demonstrated in asthma, and MMP polymorphisms are known to enhance disease susceptibility. We investigated whether MMP-1 polymorphism is associated with persistent airway obstruction in asthma in the Taiwanese population. Methods: A total of 131 unrelated Taiwanese subjects were enrolled, age-matched, and divided as follows: (1) those who had asthma with persistent airway obstruction with forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity (FVC) values less than 75% predicted (n = 41); (2) those with asthma without airway obstruction with FEV1 and FEV1/FVC values <75% predicted (n = 47); and (3) normal control subjects (n = 43). All were genotyped for the 1G/2G polymorphism of MMP-1 promoter (-1607bp). Results: 1G genotypes of MMP-1 containing at least one 1G allele were found in asthmatic patients with persistent airway obstruction (OR = 3.696, 95% CI: 1.489-9.173, p = 0.027), but not in asthmatic patients without airway obstruction (OR = 2.065, 95% CI: 0.890-4.790, p = 0.091) when compared with homozygous 2G (2G/2G). The heterozygous 1G genotype (1G/2G) was more associated with persistent airway obstruction than homozygous 2G (2G/2G) (OR: 4.727, 95% CI: 1.759-12.703, p = 0.012). The adjusted risk estimate of 1G genotypes for asthmatics with persistent airway obstruction was 4.416 (95% CI: 1.651-11.812, p = 0.003). Conclusion: 1G genotypes of MMP-1 polymorphism are associated with asthma with persistent airway obstruction, and the heterozygous 1G genotype (1G/2G) poses the most susceptibility to persistent airway obstruction in asthma.
