摘要
Genetically determined disturbances in the activity of coagulation factor VII may lead to obstetric complications. The aim of the study was to evaluate the correlation between -323P0/P10 factor VII gene polymorphism and the risk of recurrent miscarriage.The study group consisted of 152 women with a history of > or = 2 miscarriages. The control group comprised 180 women with no history of miscarriage and > or = 1 pregnancy who gave birth to a healthy newborn at term. The study group was further subdivided twice into two subgroups: 1174 patients with a history of 2 miscarriages and 38 subjects with a history of > or = 3 miscarriages, and 123 patients with miscarriages < 13 gw. and 29 with miscarriages < 21 gw. Genetic analysis was performed with the use of PCR/RFLP.Overrepresentation of P0/P0 genotype and lower frequency of P0/P10 genotype was noted in the study group as compared to controls (P0/P0: 80.26 vs. 76.67%, p = 0.25; P0/P10: 18.42 vs. 22.78%, p = 0.20). A higher presentation of P0/P0 genotype and P0 allele, lower frequency of P0/P10 genotype and P10 allele was observed in the subgroup of women with > or = 3 miscarriages as compared to controls (P0/P0: 8.84 vs. 76.67%, p = 0.12; P0: 93.42 vs. 88.06%, p = 0.12; P0/P10:13.16 vs. 22.78%, p = 0.13; P10: 11.94 vs. 6.58%, p = 0.12).The obtained results suggest a probable protective role of -323P10 allele against the risk of miscarriage in women with > or = 3 recurrent pregnancy losses.
