European Renal Best Practice endorsement of guidelines for diagnosis and therapy of thrombotic thrombocytopaenic purpura published by the International Society on Thrombosis and Haemostasis

Nephrol Dial Transplant. 2022 Jun 23;37(7):1229-1234. doi: 10.1093/ndt/gfac034.


Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disease that is caused by severe ADAMTS-13 deficiency. Immune-mediated TTP develops due to autoantibodies against ADAMTS-13, whereas congenital TTP is caused by mutations in the ADAMTS13 gene. Diagnostic possibilities and treatment options in TTP have emerged in recent years, which prompted the International Society on Thrombosis and Haemostasis (ISTH) to publish clinical practice guidelines for the diagnosis and treatment of TTP in 2020. In this article, the European Renal Best Practice Working Group endorsed the ISTH guidelines and emphasizes a number of considerations, including the importance of rapid ADAMTS-13 activity testing, the use of rituximab and anti-von Willebrand factor therapies such as caplacizumab, that enhance the clinical applicability of the guidelines in Europe.
