title: Thrombocytopenia in pregnancy: is this immune thrombocytopenia or...?
abstract: Thrombocytopenia is a common finding in pregnancy. Establishing the diagnosis of immune thrombocytopenia (ITP) in a pregnant patient is similar to doing so in a nonpregnant patient, except that the evaluation must specifically rule out other disorders of pregnancy associated with low platelet counts that present different risks to the mother and fetus and may require alternate distinct therapy. Many of the same treatment modalities are used to manage the pregnant patient with ITP, but others have not been determined to be safe for the fetus, are limited to a particular gestational period, or side effects may be more problematic during pregnancy. The therapeutic objective differs from that in chronic ITP in the adult because many pregnant patients recover or improve spontaneously after delivery and therefore maintenance of a safe platelet count, rather than prolonged remission, is the goal. Thrombocytopenia may the limit choices of anesthesia, but does not guide mode of delivery, and the fetus is rarely severely affected at birth. Patients should be advised that a history of ITP or ITP in a previous pregnancy is not a contraindication to future pregnancies and that, with proper management and monitoring, positive outcomes can be expected in the majority of patients.
