C677T Methylenetetrahydrofolate Reductase Mutation

Study Overview
=================
Brief Summary
-----------------
To investigate the effect of anticoagulant treatment on pregnancy outcomes in patients with previous recurrent miscarriages (RM) who carry a methylenetetrahydrofolate reductase (MTHFR) gene mutation. In this longitudinal retrospective study, patients with RM were treated during pregnancy with either: (i) 100 mg/day aspirin and 5 mg/day folic acid (group 1); or the same protocol plus 0.4 mg/day enoxaparin (group 2). An age-matched group of triparous women without RM or thrombophilia was used as the control group (group 3).

Detailed Description
-----------------
Recurrent miscarriage (RM) is defined as three or more consecutive spontaneous fetal losses and it affects 0.3% to 1% of pregnancies.To investigate the effect of anticoagulant treatment on pregnancy outcomes in patients with previous recurrent miscarriages (RM) who carry a methylenetetrahydrofolate reductase (MTHFR) gene mutation. In this longitudinal retrospective study, patients with RM were treated during pregnancy with either: (i) 100 mg/day aspirin and 5 mg/day folic acid (group 1); or the same protocol plus 0.4 mg/day enoxaparin (group 2). An age-matched group of triparous women without RM or thrombophilia was used as the control group (group 3).

Arms and Interventions

| Intervention/Treatment |
| --- |
|Other: infertily evaluation|All couples had undergone a standard infertility evaluation, which included medical history, physical examination, and assessment of tubal patency by either hysterosalpingography or laparoscopy and hormonal analysis on cycle day 3. A transvaginal ultrasound scan was performed on the second day of the cycle. On the same day, ovarian stimulation was carried out with recombinant FSH follitropin);rFSH;Gonal-F,MerckSerono,France,orfollitropin ; Puregon, MSD, France), urinary FSH (urofollitropin, Fostimon, France),orhMG(menotropin,Menopur,France)atastarting dose of 75 IU/day from the second day of the cycle.|
