TREATMENT STRATEGIES FOR THROMBOTIC THROMBOCYTOPENIC PURPURA: AN INTEGRATIVE REVIEW.
UMA REVISÃO INTEGRATIVA.

Púrpura Trombocitopênica Trombótica, Estratégias de Tratamento, Plasmaférese, Proteína ADAMTS13, Troca de PlasmaAbstract
The main objective of this study is to review the recent literature regarding available strategies for the treatment of Thrombotic Thrombocytopenic Purpura (TTP). It includes the evolution of the ways of diagnosis, variations in therapeutic practices, and impacts on the prognosis. This is an integrative literature review, for which consultations were carried out on the PubMed and Scientific Electronic Library Online (SciELO) data platforms. The following English terms were used: Thrombotic Thrombocytopenic Purpura; Plasmapheresis; ADAMTS13 Protein; Plasma Exchange; Plasma Drugs; Immunosuppressive Agents. As a period, publications from the last five years (2017-2022) were defined. The search resulted in 18 selected articles, which were interpreted and their results were discussed, indicating advances in treatment strategies for PTT. Studies demonstrate the search for more effective treatments, especially those capable of reducing the length of hospital stay, the mortality rate, and dependence on plasma exchange (plasmapheresis). Thus, nowadays, the standard management of TT is a triple therapy consisting of the use of caplacizumab (recently approved), combined with plasmapheresis and immunosuppression (especially rituximab). The review also provides perspectives for future treatments that are still in the very early stages of testing, highlighting: emerging anti-vWF therapies and recombinant ADAMTS13 (rADAMTS13).
