Depression and cognitive impairment following recovery from thrombotic thrombocytopenic purpura.

After recovery from an acute episode of acquired thrombotic thrombocytopenic purpura (TTP), patients often describe problems with memory, concentration, and endurance. We have previously reported the occurrence of depression and cognitive impairment in these patients. In this study, we describe the frequency, severity, and clinical course of depression and cognitive impairment.

Pregnancy outcomes following recovery from acquired thrombotic thrombocytopenic purpura.

Unlabelled: Pregnancy may precipitate acute episodes of thrombotic thrombocytopenic purpura (TTP), but pregnancy outcomes in women who have recovered from acquired TTP are not well documented. We analyzed pregnancy outcomes following recovery from TTP associated with acquired, severe ADAMTS13 deficiency (ADAMTS13 activity <10%) in women enrolled in the Oklahoma TTP-HUS Registry from 1995 to 2012. We also systematically searched for published reports on outcomes of pregnancies following recovery from TTP associated with acquired, severe ADAMTS13 deficiency.

Multiple major morbidities and increased mortality during long-term follow-up after recovery from thrombotic thrombocytopenic purpura.

Recovery from acute episodes of thrombotic thrombocytopenic purpura (TTP) appears complete except for minor cognitive abnormalities and risk for relapse. The Oklahoma TTP-HUS (hemolytic uremic syndrome) Registry enrolled 70 consecutive patients from 1995 to 2011 with ADAMTS13 activity <10% at their initial episode; 57 survived, with follow-up through 2012. The prevalence of body mass index (BMI), glomerular filtration rate (GFR), urine albumin/creatinine ratio (ACR), hypertension, major depression, systemic lupus erythematosus (SLE), and risk of death were compared with expected values based on the US reference population.

Decreasing frequency of plasma exchange complications in patients treated for thrombotic thrombocytopenic purpura-hemolytic uremic syndrome, 1996 to 2011.

Background: Plasma exchange (PEX) treatment for patients with thrombotic thrombocytopenic purpura-hemolytic uremic syndrome (TTP-HUS) has risk for major complications.

Study Design And Methods: Data for PEX-related complications have been prospectively collected on all patients enrolled in the Oklahoma TTP-HUS Registry, 1996 to 2011. PEX-related complications have been defined as major or minor and as central venous catheter related or plasma related.
