title: Successful pregnancies of two patients with relapsing thrombotic thrombocytopenic purpura.
abstract: Thrombotic thrombocytopenic purpura is a severe multisystemic disorder of unknown origin. The association of relapsing TTP with pregnancy is rare but well documented and high mortality rates of mothers and fetuses have been reported so far. Since the introduction of plasma therapy for treating the acute exacerbations of the disease, overall mortality rates have decreased significantly. It is now evident that the manifestations of the disease may reappear even after long disease-free intervals and as many as a third of the recovering patients may develop a relapse. Presented are two TTP patients with relapsing TTP complicating their pregnancies. Prophylactic treatment with aspirin and dipyridamole during their last three successful pregnancies prevented or minimized the severity of TTP relapses. The course of these pregnancies and the management of such patients is discussed.
