Abstract/OtherAbstract:
Background: Early-onset hypertensive disorders of pregnancy (HD) and small-for-gestational age infants (SGA) are associated with placental vascular thrombosis, often recur and are also associated with inheritable thrombophilia. Aspirin reduces the recurrence risk. Objective: Adding low-molecular-weight heparin (LMWH) to aspirin at <12 weeks gestation reduces recurrence of HD in women with previous early-onset HD (preeclampsia, HELLP syndrome, eclampsia) and/or SGA, in the context of inheritable thrombophilia without antiphospholipid antibodies. Patients/Methods: In a multicenter RCT, 139 women were included <12 weeks gestation. Inclusion criteria: previous delivery <34 weeks gestation with HD and/or SGA; inheritable thrombophilia (protein C deficiency; protein S deficiency; activated protein C resistance; Factor V Leiden heterozygosity; prothrombin gene G20210A mutation heterozygosity); no antiphospholipid antibodies detected. Intervention: either daily LMWH (dalteparin, 5000 IU weight-adjusted dosage) with aspirin 80 mg or aspirin 80 mg alone. Main outcome measures: Primary outcomes: recurrent HD onset 1) <34 weeks gestation and 2) irrespective of gestational age. Secondary outcomes: recurrent SGA, preterm birth, maternal/neonatal hospitalization, spontaneous abortion, individual HD. Analysis by intention-to-treat. Results: LMWH with aspirin reduced recurrent HD onset <34 weeks gestation (risk difference (RD) 8.7%: CI of RD 1.9-15.5%; p=.012; NNT 12). Recurrent HD irrespective of gestational age was not different between arms. No women withdrew for adverse effects. Trial Registration: http://www.isrctn.org (isrctn87325378). Conclusions: Adding LMWH to aspirin at <12 weeks gestation reduces recurrent HD onset <34 weeks gestation in women with inheritable thrombophilia and prior delivery for HD/SGA <34 weeks. Close monitoring of mother and fetus remains important throughout pregnancy.
