The association of maternal and neonatal thrombocytopenia in high-risk pregnancies.
In this study of 136 women with pre-eclampsia, eclampsia, placenta previa, or abruptio placentae, 21 mothers were noted to have thrombocytopenia. Seventeen of the 21 were in the pre-eclampsia group. Of the 21 thrombocytopenic mothers, nine were associated with thrombocytopenia in the children, seven children had normal platelet counts, and five had no counts performed. Eight of the nine thrombocytopenic neonates were associated with pre-eclampsia in the mother, and five of these were not believed to have disseminated intravascular coagulation as the etiology of the platelet defect. The results suggest that thrombocytopenia is common in high-risk pregnancies in both the mother and the baby. However, the etiology of the platelet defect cannot be easily explained on the basis of a hypercoagulable state.
