Brief Summary

HSCT associated thrombotic microangiopathy(TA-TMA) is a heterogeneous, fatal disorder seen within 100 days post-transplant and presents with thrombocytopenia, hemolysis, acute renal failure, mental status changes and involvement of other organs. N-Acetylcysteine (NAC) is a small, simple molecule that began as a generic drug almost 40 years ago. It has since been approved by the FDA for many indications. The investigators conducted an prospective clinical trial to evaluate the safety and efficiency of NAC in patients with TA-TMA.

Limitations and Caveats

Several outcome indicators are entirely inconsistent with our study's actual course of execution. First, the occurrence of TA-TMA was not limited to the first 100 days after hematopoietic stem cell transplantation. Secondly, the detection of VWF multimers, endothelial microparticles, and ROS was not performed according to the protocol.
