Prolonged Isolated Thrombocytopenia After Allo-SCT : N-acetyl-L-cysteine (NAC) Versus Supportive Therapy
September 23, 2020 updated by: Xiaojun Huang,MD, Peking University People's Hospital
A Prospective Randomized Controlled Study for Intervention of Prolonged Isolated Thrombocytopenia After Allogeneic Hematopoietic Stem Cell Transplantation: N-acetyl-L-cysteine (NAC) Versus Supportive Therapy
Isolated prolonged thrombocytopenia (PT) is a common complication after allogeneic stem cell transplantation with significant poor prognosis.
No standard treatment is available.
The current study assigned PT randomly to 2 arms: intervention arm with N-acetyl-L-cysteine (NAC) and control arm with supportive therapy.This is a prospective randomized controlled study.

Intervention / Treatment
Detailed Description
- patients diagnosed with PT at day 60 post transplant will be randomized assigned to intervention arm (NAC) or controlled arm (supportive therapy: prophylactic platelet transfusion was given when platelet count <20000/ul.)
- Response will be evaluated at day 90. Response was defined as platelet recovery to >= 20000/ul for 7 consecutive days without transfusion support during the enrollment period. All the other patients not achieved above criteria was defined as no response.
- For those without response in both arms, patients will received NAC plus recombinant human thrombopoietin (rhTPO) for an additional 30 days. rhTPO was given at 300IU/kg/d for 28 consecutive days or platelet > 50000/ul independent of platelet transfusion.
