Prednisone therapy for acute graft-versus-host disease: short- versus long-term treatment. A prospective randomized trial. A prospective randomised trial of cyclosporin and methotrexate versus cyclosporin, methotrexate and prednisolone for prevention of graft-versus-host disease after HLA-identical sibling marrow transplantation for haematological malignancy.
We report the results of a controlled study in which BMT patients with moderate/severe acute graft-versus-host disease (GVHD) who responded to primary treatment with corticosteroids were prospectively randomized to short versus long taper of their steroid doses. Thirty patients with moderate/severe acute GVHD who responded by 14 days were eligible for random assignment of their steroid tapering schedule. Patients in the short taper group received a total PRED dose of 2275 mg/m2 over 86 days, whereas those in the long taper group received 6300 mg/m2 over 147 days. Patients in the long taper group achieved resolution of acute GVHD after a median of 30 days of therapy (range 6-30), whereas those receiving the short taper resolved after a median of 42 days (12-74) (P = 0.01). After 8 weeks of therapy, only 2 of 13 evaluable long taper and 3 of 13 short taper patients still had active GVHD. The median PRED dose required to achieve complete resolution of acute GVHD was not different between the two groups: 1300 mg/m2 for the long taper patients and 1800 mg/m2 for the short taper patients. Importantly, the incidence of chronic GVHD and survival at 6 months was similar in the 2 groups. The incidence of steroid-related complications was similar, as well. This study suggests that the rapid administration of high-dose PRED to a cumulative dose of 2000 mg/m2 might lead to complete and prompt resolution of acute GVHD in the majority of patients and that rapid PRED taper might provide a mechanism for minimizing steroid-related morbidity. Further investigation and formal studies of the dose-response relationships and kinetics of steroid administration may lead to improvement in the management of acute GVHD. A prospective randomised trial was performed in patients given HLA-identical sibling bone marrow transplants for haematological malignancy comparing the combination of cyclosporin and methotrexate (CM) (n = 20) with the combination of cyclosporin, methotrexate and prednisolone (CMP) (n = 21) as prophylaxis for graft-versus-host disease (GVHD). There was no significant differences between the two arms for the incidence of acute GVHD grades I-IV, acute GVHD grades II-IV, chronic GVHD, interstitial pneumonitis, relapse, survival and disease-free survival. The actuarial incidence of acute GVHD grades II-IV in the CMP group was 10% and in the CM group 15% (ns). The incidence of leukaemic relapse in good risk patients was 42% in the CMP group and 40% in the CM group (ns), although the majority of these relapses were cytogenetic relapses only in patients with chronic myeloid leukaemia. The incidence of acute GVHD grades II-IV in both arms of the current trial was significantly lower than in our previous trial comparing cyclosporin and methotrexate as single agents. Leukaemic relapse is now the principal cause of treatment failure in this patient population. We conclude that prednisolone should not be included as part of the prophylactic GVHD regime and that further improvement in therapeutic outcome is dependent upon better control of the underlying malignancy.
There is no certain study regarding appropriate use, dose and length of therapy for acute GvHD. Further studies are needed to define the appropriate use of steroids and whether other agents are appropriate as frontline therapy.
