Prolonged Isolated Thrombocytopenia After Allo-SCT : N-acetyl-L-cysteine (NAC) Versus Supportive Therapy

Overview

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.

1. 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.) 2. 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. 3. 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.
