ABSTRACT
Idiopathic thrombocytopenic purpura (ITP) occurs more commonly in young women during the reproductive years. To obtain information for management of ITP in pregnancy, we performed a nationwide retrospective survey. Findings from a total of 284 pregnant women with ITP and their 286 newborn infants were available for analysis. The bleeding tendency at delivery was managed chiefly with corticosteroid, intravenous high-dose gamma-globulin, and platelet transfusion. Maternal complications occurred in 77 cases (27.1%) and were frequently seen in cases with poor control of ITP. Neonatal abnormalities, which were not influenced by the clinical state of the mother, occurred at a frequency of 17.8%. Thrombocytopenia in neonates occurred in 48 cases (22.4%), and bleeding tendency was found in 16 cases (6.3%) without severe bleeding. Prediction of thrombocytopenia in neonates was difficult. However, infants from splenectomized mothers with well-controlled ITP showed thrombocytopenia more frequently than those from nonsplenectomized mothers. Mothers treated with steroids at doses greater than 15 mg/day showed a high frequency of maternal complications and fetal abnormal body weight. These observations will be useful in the management of pregnant women with ITP and their infants.

To investigate the efficacy and safety of granulocyte colony-stimulating factor (G-CSF) in patients with acute myelogenous leukaemia, a multicentre randomized study was performed. From October 1993 to September 1996, 270 patients with newly diagnosed acute myelogenous leukaemia were randomized to G-CSF or control groups after remission induction therapy. The G-CSF group received G-CSF (Filgrastim) from 48 h after the completing chemotherapy until the absolute neutrophil count exceeded 1.5 x 10(9)/l. The control group did not receive G-CSF unless severe infection occurred. There were 245 evaluable patients (120 and 125 in the G-CSF and control groups respectively). The complete remission rate was similar in the G-CSF and control groups (80.8% versus 76.8%), as was the 5-year probability of disease-free survival (34.5% versus 33.6%) and overall survival (42.7% versus 35.6%). Neutrophil recovery was significantly faster in the G-CSF group than in the control group (12 d versus 18 d, P = 0.0001). The median duration of febrile neutropenia was significantly shorter in the G-CSF group than in the control group (3 d versus 4 d, P = 0.0001). In conclusion, prophylactic administration of G-CSF after remission induction therapy for acute myelogenous leukaemia is safe and useful even in patients without infection on completing chemotherapy.
