Protein�A immunoadsorption therapy for refractory, mitomycin�C?associated thrombotic microangiopathy
2007
BACKGROUND: Mitomycin C–associated thrombotic microangiopathy (TMA) has a poor prognosis with limited therapeutic options. Most patients die within 4 months of diagnosis due to pulmonary or renal failure. Here, a patient resistant to total plasma exchange (TPE) and immunosuppressive therapy with glucocorticoids, rituximab, vincristine, and splenectomy who was successfully treated with protein A immunoadsorption is described. CASE REPORT: A 29-year-old woman developed a TMA after chemotherapy with mitomycin C. She presented with thrombocytopenia, pulmonary edema, hemolytic anemia with presence of schistocytes, and renal failure. Immediate TPE (>120 times) and immunosuppressive therapy with g…
Atypical presentations of thrombotic thrombocytopenic purpura in middle-aged women with recurrent cerebral macrovascular thrombosis: a case report
2015
Dear Editor, In the current clinical practice, minimal criteria to define thrombotic thrombocytopenic purpura (TTP) are the presence of signs of microangiopathic haemolytic anaemia and low platelet (PLT) count [1]. TTP relapses (20–50 % of cases) are defined as the recurrence of acute TTP symptoms 30 days after the first episode, while exacerbations occur within 30 days [2]. We here report on an atypical case of acquired TTP where minimal criteria were met only after many recurrent macrovascular ischemic events. A 42-year old Caucasian woman with a history of coronary and cerebral ischemic events was admitted on June 2013, following a recurrent transient ischemic attack (TIA). She had sever…
Reversible posterior leukoencephalopathy syndrome in a patient with thrombotic thrombocytopenic purpura
2011
Thrombotic thrombocytopenic purpura (TTP) is an autoimmune disorder characterised by fever, microangiopathic haemolytic anaemia, renal insufficiency, and thrombocytopenia. Neurological involvement, a prominent component of TTP, is characterised by a variety of brain lesions which include reversible cerebral oedema or magnetic resonance imaging (MRI) features of reversible posterior leukoencephalopathy syndrome (RPLS). TTP is frequently associated with deficiency of the von Willebrand factor-cleaving protease, ADAMTS13.Here, we report a case of TTP with severe acute encephalopathy. Posterior leukoencephalopathy and brainstem oedema with triventricular hydrocephalus were observed on MRI. The …
Haemolytic-uraemic syndrome during severe lupus nephritis: efficacy of plasma exchange
2012
Systemic lupus erythematosus (SLE) has been described as a cause of thrombotic microangiopathy, especially thrombotic thrombocytopenic purpura (TTP). Haemolytic-uraemic syndrome (HUS) is less frequent in SLE. We report a case of such an association during an episode of severe lupus nephritis in a young woman, who was successfully treated with steroids, cyclophosphamide and especially plasma exchange with plasma replacement. This report highlights the importance of recognising atypical HUS in SLE patients by looking for schistocytes in case of haemolytic anemia with a negative antiglobulin test, in order to begin plasma exchange.
