Abstract
Acquired thrombotic thrombocytopenic purpura (aTTP) is a rare hematological emergency characterized by microangiopathic hemolytic anemia, thrombocytopenia, fever, and multiorgan failure due to autoimmune-mediated deficiency in ADAMTS-13 activity. Currently, plasma exchange, with or without steroids, is the frontline option for the management of aTTP. The treatment should be started promptly once the disorder is clinically suspected. Besides, immunomodulators were studied in patients with aTTP to achieve stable remission and reduce the risk of relapse in patients with suboptimal response to plasma exchange; however, clinical trials showed equivocal results. Published data on early diagnosis, referral, and treatment patterns of aTTP patients in the member nations of the Arabian Gulf Cooperation Council (GCC) are still lacking. Therefore, the present consensus report aimed to present an overview of aTTP situation in GCC by bringing together a panel of experts from three GCC nations, to share their views on current trends and practices regarding aTTP. The experts discussed challenges including the lack of reliable data regarding the incidence of aTTP in GCC and delayed results of ADAMTS-13 activity testing. Limited patient access to tertiary centers and low level of awareness about the aTTP clinical spectrum among general practitioners are other challenges. The experts agreed that there is a need for national and regional consensus regarding the diagnosis and treatment of aTTP in the Gulf region.
