Abstract:
Objective To evaluate the effectiveness and side-effects of antithymocyte globulin(ATG) and antilymphocyte globulin(ALG) in nonmyeloablative stem cell on transplantation complication.Methods Fourteen cases of hematologic malignancies and 11 cases of sever aplastic anemia(SAA) were treated with allogenic bone marrow transplantation or cord blood haemopoietic stem cell transplantation based on ATG/ALG.Five patients with malignant hematonosis were received donor lymphocyte infusion(DLI) after transplantation.The protocols for graft-versus-host disease(GVHD) prophylaxis consisted of Cyclosporin A(CSA) and methotrexate(MTX) for malignant hematonosis patients or CSA and methylprednisolone(MP) for patients with SAA.Results Three patients had not evidence of engraftment and died from infection at early stage.Other patients recovered haematopoiesis.The mean time of ANC more than 0.5?10~9/L and Plt more than 20?10~9/L were 12.1(3～29) and 20.1(5～79) days posttransplant respectively.Three patients achieved donor complete chimera(CC).Five malignant patients with transient mixed chimerism(MC) grdually converted into complete chimerism by DLI post transplant.Nineteen patients achieved MC and four of them coverted into donor haematopoietic cell complete chimerism.There was no aGVHD in early stage post transplant.There were 1 patient with Ⅰgrade aGVHD,3 with Ⅱgrade aGVHD,2 with skin local cGVHD and 2 with extensive cGVHD after DLI,respectively.There were 2 patients with bacteria infection complications,4 with virous infection and 5 with fungal infection.All patients complicated with chills and fever in the use of ATG and ALG.Conclusion Treatment with ATG and ALG is safety and tolerant for the patients,and can enhance the engraftment of haemopoietic stem cell and decrease the aGVHD.
