Summary

To evaluate the efficacy and safety of donor EBV-specific T lymphocytes (EBV-CTL) infusion in patients with chronic active Epstein-Barr virus infection (CAEBV) and EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) after allogeneic hematopoietic stem cell transplantation (allo-HSCT)

Conditions

  • Chronic Active Epstein-Barr Virus Infection
  • Virus-Associated Hemophagocytic Syndrome

Interventions

OTHER

donor EBV-specific T lymphocytes

EBV-DNA reactive after transplantation, or did not turn negative after +30 days, peripheral blood lymphocytes of the donor were collected to prepare EBV-CTL, and the first transfusion of EBV-CTL 6.0x105 was given at 48h to rapidly culture EBV-CTL, then EBV-CTL 6.0x105/kg was injected once a week untile EBV-DNA negative for 2 consecutive times or GVHD happened. After the second infusion, EBV-DNA did not decrease and there was no aGVHD patients, EBV-CTL infusion volume was increased to 1.2x106/kg, once a week. After 2 cycle infusion, EBV-DNA still did not decrease, and the reinfusion was terminated. Peripheral blood lymphocytes were collected from donors of high-risk patients at +14 days after allogeneic hematopoietic stem cell transplantation to prepare EBV-CTL, and EBV-CTL 6.0x105/kg was infused at +21d, +28d, +35d and + 42D for prevention. During treatment, if the patient develops GVHD, the infusion should be stopped.
