Although numerous studies are available in literature, thrombophilia rate seems to vary fromstudy to another. The aim of our study was to determine the frequency of FII Prothrombin(G20210A), Factor V Leiden (G1691A), as well as methyl tetrahydrofolate reductase (MTHFR?C677T) polymorphisms, protein C, protein S and antithrombin III deficiency in a series of patients with unexplained RPL compared to control. Patients and Methods: 100 patients of unexplained RPL and 43 age-matched healthy controls were investigated for inherited thrombophilia. Results: MTHFR and Factor V Leiden were the commonest gene defects among cases studied (63%, 60% respectively) and control groups (41.9%, 41.9% respectively) (p = 0.019, p = 0.046 respectively). The least common deficiencies were protein S and protein C deficiency in cases (3%, 2% respectively) as well as in controls (1%, 0% respectively). 4 cases were homozygous for MTHFR and 2 cases homozygous for Factor V Leiden mutation. Odds ratio for MTHFR and Factor V mutation was 2.36 and 2.08 respectively (CI 95%). Combined defects were seen in cases and controls (p < 0.05). Conclusion: Our study found an association between MTHFR and Factor V Leiden mutations in patients with unexplained RPL among Egyptian women. Further studies are needed to define the management of genetic thrombophilia in cases of recurrent pregnancy loss.展开更多
