Effectiveness of Bemiparin Sodium for Preventing Pregnancy Loss in Patients with MTHFR C677T Mutation and Habitual Abortus
Abstract: Objective: In this study the purpose is to evaluate the effectiveness of daily bemiparin sodium injection in preventing early pregnancy loss and in achieving live births in pregnant patients, not ahead of 6th week, who are diagnosed with habitual abortion in a case-controlled randomized prospective study. Study Design: In this prospective study, 120 pregnant patients not ahead of 6th week and aged between 21 - 36 and diagnosed with habitual abortion between April 2011 and April 2012 in our clinic were included. Habitual abortion diagnosis criteria was based on patient history of three or more miscarriages before the 20th week and a genetically documented homozygote or heterozygote mutation of the methylenetetrahydrofolate Reductase gene. Results: The rate and the number of live births in the study group was 60 (93.75%) and statistically higher than the control group 32 (57.14%). The difference was found to be statistically significant (p = 0.001). The rate and the number of abortions in the control group was 24 (42.85%) and statistically higher than the study group 4 (6.25%). The difference was found to be statistically significant (p = 0.001). Conclusion: In order to maintain a healthy pregnancy an effective uteroplacental circulation is a must and any defects in haemostasis mechanisms may have an adverse influence. A few non-randomized studies comparing pregnancy results of low dose salycilic acid and low molecular weight heparin usage in patients also show that prophylaxis might be beneficial.
