Thrombotic thrombocytopenic purpura (TTP) is a systemic disorder that classically results from a deficiency in the von Willebrand factor-cleaving enzyme, ADAMTS13. The human immunodeficiency virus (HIV) is a secondary cause of TTP. It has been recognized that some patients with HIV-associated TTP do not have a deficiency in ADAMTS13 activity. The role of plasmapheresis (PLEX) in these patients is unclear. This study reviewed 8 cases of HIV-associated TTP at Thomas Jefferson University Hospital. All patients responded to treatment; however, we were unable to make any conclusions regarding the use of PLEX in patients with normal ADAMTS13 activity. HAART initiation is recommended to treat the underlying HIV infection.
