Treatment of high risk pregnancies

Summary Introduction: The efficacy of a therapy with certoparin; also in combination with aspirin and prednisolone; in high-risk pregnancies has been examined prospectively. Method: Data of 616 pregnancies have been analyzed. 238 patients injected Mono Embolex 3000; 239 patients Mono Embolex 8000 only. 62 patients injected Mono Embolex 8000 and took aspirin 50–100 mg daily; 60 Mono Embolex 3000 and aspirin 50–100 mg daily. 30 patients took aspirin 50–100 mg; prednisolone 2.5–5 mg and 17 injected mono Embolex 8000; 13 Mono Embolex 3000 daily from the start of their pregnancy. The target variable was the life birth rate. When given aspirin the HPA-status of the partner is measured if the pregnant woman is negative for HPA 1a or 5b. In HPA-negative mothers and HPA-positive fathers a test for HPA-antibodies is performed posterior week 16. Result: Applied early; a mean life birth rate of 95 % has been achieved in the monotherapy with Mono Embolex. Where heparin and aspirin were applied before pregnancy week 17 a life birth rate of 100 % was achieved. In patientswith a combination of aspirin and prednisolone a life birth rate of 87 % was achieved. Considering the life birth rate the status of thrombophilia gene-polymorphisms is irrelevant. The HPA-status was examined in 139 patients. In one of the HPA 5a-negative and 3 of the HPA 5b-negative women an immunization occurred but the platelet count of the fetus was not decreased. 3.3 % showed local allergic reaction and 0.5 % slight bleeding. Conclusion: Certoparin, aspirin and prednisolone are safe drugs to increase life birth rate.
