The importance of parity to major maternal morbidity in the eclamptic mother with HELLP syndrome.
OBJECTIVE
To determine if the rate of major morbidity from severe preeclampsia with/without hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome differs by parity.


METHODS
Retrospective investigation of 970 gravidas with severe preeclampsia with and without HELLP syndrome analyzed according to parity.


RESULTS
Altogether 609 (63%) patients were nulliparous and 361 (37%) parous. Between groups there was no significant difference in the incidence of overall major morbidity (21% vs. 19%, p=0.467), or specific morbidities including hematologic/coagulopathic (13.6% vs. 11.9%, p=0.442), cardiopulmonary (8.9% vs. 7.2%, p=0.362), CNS/visual (1.8% vs. 2.8%, p=0.319), or hepatorenal (0.8% vs. 2.2%, p=0.068). Although eclampsia was significantly more common in nulliparous (10.2%) than in parous patients (5.5%, p=0.012), the later significantly more often demonstrated major maternal morbidity associated with eclampsia (50%) than did nulliparous patients (25%, p=0.043).


CONCLUSIONS
Unless parous patients with severe preeclampsia with or without HELLP syndrome develop eclampsia, their disease acuity does not differ significantly from their nulliparous counterparts.
