Abstract
OBJECTIVE: The aim of present study was to determine the role of matrix metalloproteinase-8 (MMP-8) C-799T (rs11225395) and C+17 (rs2155052) polymorphisms in susceptibility to preeclampsia. STUDY DESIGN: In a case-control study, 256 pregnant women including 152 women with preeclampsia (86 women with mild preeclampsia and 66 women with severe preeclampsia) and 104 women with normal pregnancy from Western Iran with Kurdish ethnic background were investigated for MMP-8 C-799T and C + 17G polymorphisms using polymerase chain reaction-restriction fragment length polymorphism method. RESULTS: Comparing the MMP-8 TT genotype with the combined genotype of CC+CT (recessive model) indicated a significantly higher frequency of the MMP-8 TT genotype (47%) in severe preeclamptic patients than that in healthy pregnant women (30.8%) that was associated with 1.99-fold increased risk of severe preeclampsia (95% CI = 1.05-3.77, p = 0.034). The frequency of MMP-8 G allele was 27.3% in all preeclamptic patients compared to 30.2% in controls (p = 0.56). Also, no significant difference was detected comparing the frequency of G allele in mild (26.6%, p = 0.46) and severe preeclamptic patients (28.4%, p = 0.75) with controls (30.2%). CONCLUSIONS: Our study demonstrated that the MMP-8 C-799T is associated with the risk of developing severe preeclampsia during pregnancy. However, the MMP-8 C + 17G polymorphism might not be a risk factor for susceptibility to preeclampsia.
