[Cesarean section combined with splenectomy in severely resistant immune thrombocytopenia].

Immune thrombocytopenic purpura (ITP) associated with pregnancy often involves considerable risk both for mother and child, and usually worsens in the third trimester of gestation. Pregnancy and delivery are especially difficult in patients with severe ITP (platelet count below 20 x 10(9)/L), who are resistant to prednisone and high dose intravenous immunoglobulin (IVIgG). In those cases we applied cesarean section (CS), to prevent intracranial haemorrhage due to fetal/neonatal ITP, and splenectomy at the same time as an effective therapeutic strategy for ITP. We present 5 patients (4 with chronic ITP and 1 with ITP associated with HIV infection), aged 21-35 years, with severe ITP (platelet count 2-10 x 109/L), resistant to prednisone (1-2 mg/kg), and 2/3 were resistant to IVIgG (0.4 g/kg x 5 d). Four patients with severe resistant ITP were supported with 1-2 doses of platelets from cell separator before CS and 1-3 dose during splenectomy. One patient increased platelet count to 55 x 109/L after treatment with IVIgG and splenectomy following CS were done without platelet transfusion. Splenectomy was performed immediately after CS in all patients, and two of them were hysterectomised (one with HIV infection). After splenectomy, platelet count was normalised in all patients, and they had no haemorrhage, wound haematoma formation or any adverse events. But ITP relapsed in 2/5 patients after 1-2 months. Two newborns had severe thrombocytopenia, which solved spontaneously after 3 days in one or after treatment with IVIgG in other. We propose that splenectomy following cesarean section should be considered as approach for delivery and treatment option for mothers with severe resistant ITP.
