Thrombotic thrombocytopenic purpura associated with HIV infection: report of two cases.
نویسندگان
چکیده
We report two cases of thrombotic thrombocytopenic purpura (TTP) in advanced stage HIV-positive patients (CD4+ < 0.05 x 10(9)/L). Clinical symptoms were relevant, but their course was not fulminant; the two patients responded to different therapies (plasma or plasma plus plasmapheresis, and steroids), showing rapid improvement in symptoms. One patient remained asymptomatic with zidovudine only, while the other relapsed (probably due to an intercurrent infection). This second person is now asymptomatic on zidovudine plus low doses of steroids.

Thrombotic thrombocytopenic purpura (TTP) is mostly attributed to the presence of an autoantibody against ADAMTS-13, a metalloprotease that degrades ultralarge von Willebrand protein multimers. Accumulation of vWF multimers and systemic platelet aggregation lead to microangiopathic thrombosis, hemolytic anemia, and end-organ ischemia. Most patients respond to therapeutic plasma exchange (TPE), ...

Thrombotic Thrombocytopenic Purpura (TTP) is a rare microangiopathic disorder characterised by the pentad of microangiopathic hemolytic anemia, thrombocytopenic purpura, neurologic abnormalities, fever, and renal disease. Decreased production and/or activity of ADAMTS13 is the cause of this disorder. ADAMTS13 is a metalloproteinase which is responsible of the cleavage of high weight multimers o...

Background and Aim: Thrombotic thrombocytopenic purpura is a rare and life-threatening disease with a relatively high prevalence of 5% in pregnancy that causes thrombocytopenia. Due to the high prevalence and mortality of fetal and maternal mortality, which resolves rapidly with the onset of plasmapheresis, the diagnosis of this disease is clinically important. The aim of this study was to succ...
