| Abstrakt: | Background: The incidence of neonatal hypoxic-ischemic encephalopathy (HIE) is reportedly high in countries with limited resources. Its pathogenesis is multifactorial. A role for thrombophilia has been described in different patterns of preterm and full-term perinatal brain injury. Aim: This study aims to identify risk factors associated with neonatal HIE and also to determine the contributions of genetic thrombophilia in the development of neonatal HIE. Methods: Sixty-seven neonates with HIE and 67 controls were enrolled in the study. Clinical history and examination were undertaken. Patients and controls were tested for the presence of factor V G1691A and prothrombin G20210A mutations. In addition, protein S, protein C, and antithrombin III levels were assessed. Results: Parental consanguinity and performing emergency cesarean section (CS) were significant risk factors for neonatal HIE (odds ratio [OR] 6.5, 95% confidence interval [CI] 2.6-15.3, P < .001, OR 12.6, 95% CI 2.52-63.3, P = .002, respectively). No significant difference was found regarding maternal age and parity. About 33% of cases and 6% of controls were found to have at least 1 thrombophilic factor ( P < .001). Factor V G1691A mutation significantly increased the risk of neonatal HIE (OR 4.5, 95% CI 1.4-14.5, P = .012), while prothrombin G 20210A mutation and protein C deficiency were not. Conclusion: Parental consanguinity, emergency CS, and factor V mutation may contribute to the higher risk of developing neonatal HIE. |
