Clinical aspects of pregnancy and delivery in patients with chronic idiopathic thrombocytopenic purpura (ITP).
BACKGROUND
Idiopathic thrombocytopenic purpura (ITP) is a condition that often develops in young women and, consequently, physicians should frequently manage and monitor pregnant patients with this disorder.


METHODS
We reviewed the charts of 30 women with chronic ITP delivered in 31 pregnancies from January 1995 to December 2003.


RESULTS
Fifteen patients were diagnosed with ITP before pregnancy and sixteen patients were diagnosed during pregnancy. The mean platelet counts before pregnancy, during pregnancy, and at delivery were 70,040/mm3, 83,960/mm3, and 62,680/mm3, respectively. The symptoms of hemostatic impairment were not noted in most of the pregnancies (77%, 24/31). During pregnancy and at delivery, most of the women (61%, 19/31) received various kinds of treatment to raise platelet counts. At delivery, the most commonly used therapy was platelet transfusion (48.4%, 15/31). Seven pregnancies (22.6%) were treated with corticosteroids during pregnancy and at delivery. Five pregnancies (16.1%) were treated with IV IgG during pregnancy and at delivery. Fifteen deliveries (51.7%) were performed by cesarean section and fourteen (48.3%) with vaginal delivery. Bleeding was uncommon at delivery. There were no cases of infants with any clinical signs of hemorrhage.


CONCLUSIONS
Our current results suggest that ITP in pregnancy can proceed safely with low hemorrhagic risk in both infants and mothers, and that mothers with ITP can deliver healthy infants without serious hemorrhagic complications.
