Abstract

Hematopoietic stem cell transplantation-associated thrombotic microangiopathy (TA-TMA) is a fatal post-transplant complication. It has a high mortality rate and worse prognosis, but treatment strategies remain controversial. We screened 6 out of 3453 studies on the treatment of TA-TMA. These investigations compared 5 treatment strategies with a network meta-analysis approach. The final outcome was the proportion of patients who responded to these therapies. There were significant differences in response rates for each treatment. Achieving analysis through direct and indirect evidence in the rank probabilities shows that rTM (recombinant human soluble thrombomodulin) is most likely to be rank 1 (64.98%), Eculizumab intervention rank 2 (48.66%), ISM (immunosuppression manipulation) rank 3 (32.24%), TPE (therapeutic plasma exchange) intervention rank 4 (69.56%), and supportive care intervention rank 5 (70.20%). Eculizumab and ISM have significantly higher efficacy than supportive care (odds ratio (OR): 18.04, 18.21 respectively); and TPE having lower efficacy than all other TA-TMA therapies exception to supportive care. In our study, rTM and Eculizumab may be the best choice when treating TA-TMA.
