Objective:
Transplantation-associated thrombotic microangiopathy (TA-TMA) is a severe thrombotic complication that occurs after hematopoietic stem cell transplantation. Currently, there are no clear conclusions on the factors influencing the prognosis of TA-TMA patients and the best treatment plan for TA-TMA.
Methods:
We retrospectively collected information on 26 patients with TA-TMA from a single center. The independent factors affecting prognosis were analyzed through univariate and multivariate Cox regression. Subgroup analysis was also conducted to investigate the impact of different treatment methods on overall survival of patients.
Results:
We found that high creatinine levels during the diagnosis of TA-TMA and previous CAR-T cell therapy were independent risk factors affecting the prognosis of TA-TMA patients. Additionally, discontinuing calcineurin inhibitors (CNI) is helpful in prolonging the survival period of TA-TMA patients.
Conclusions:
Our research has revealed the high-risk factors affecting the survival of TA-TMA patients and the efficacy of different treatment methods, providing guidance for subsequent clinical practice.
