NCT01661439

Brief Summary

Preconceptional use of low molecular weight heparin (enoxaparin) and aspirin in patient with recurrent miscarriages with positive anti phospholipid antibodies increase the implantation rate and the duration of pregnancy with low complications to the mother and the baby.

Outcome Measures

Primary Outcomes (1)

  • Pregnancy continuation beyond twelve weeks gestation

    giving low molecular weight heparin (enoxaparin) and 81 mg aspirin in patients with positive anti phospholipid antibodies with history of recurrent miscarriages or intrauterine fetal deaths in the preconceptional period one month before pregnancy with follow up as regarding the clinical pregnancy rate,the rate of continuation of pregnancy beyond 28 weeks gestation and the complications related to long term use of heparin and the severity of complication of APS in comparison to the traditional use of anticoagulant after documentation of the fetal heart rate

    ONE YEAR

Study Arms (1)

Low molecular weight heparin

SC LMWH IN patients with recurrent pregnancy loss

Drug: low molecular weight heparin (enoxeparine)

Interventions

1mg/kg enoxeparine SC daily from 1st day of the menstrual cycle and continue daily throughout the pregnancy after documentation of pregnancy,and stopped in absence of fetal cardiac activity.

Study Population

patients with recurrent pregnancy losses either two or more recurrent miscarriages or intrauterine fetal deathes after 20 weeks of gestation with positive antiphospholipid antibodies in medium to high titer in two occasions 6 weeks apart.

You may qualify if:

  • All women with recurrent first-trimester miscarriage and all women with one or more second-trimester miscarriage who screened before pregnancy for antiphospholipid antibodies.
  • To diagnose antiphospholipid syndrome it is mandatory that the woman has two positive tests at least 12 weeks apart for either lupus anticoagulant or anticardiolipin antibodies of immunoglobulin G and/or immunoglobulin M class present in a medium or high titre over 40 g/l or ml/l,or above the 99th percentile).
  • In the detection of lupus anticoagulant, the dilute Russell's viper venom time test together with a platelet neutralisation procedure is more sensitive and specific than either the activated partial thromboplastin time test or the kaolin clotting time test. Anticardiolipin antibodies are detected using a standardised enzyme linked immunosorbent assay.

You may not qualify if:

  • Age above forty years old .
  • Intrauterine abnormalities (as assessed by ultrasound, hysterosonography, hysterosalpingogram, or hysteroscopy).
  • Fibroids distorting uterine cavity .
  • Abnormal parental karyotype .
  • Other identifiable causes of recurrent miscarriages (tests initiated only if clinically indicated) e.g., diabetes, thyroid disease and systemic lupus erythematosus (SLE).
