Abstract

Introduction: Continuous infusion (CIVI) cyclosporine (CsA) is an alternative for allograft recipients intolerant of twice daily infusions (TDI). The importance of achieving therapeutic levels of CsA early after allogeneic HCT has been demonstrated in previous studies. Our study evaluated the incidence of acute graft versus host disease (GVHD) and survival among patients receiving CIVI vs. TDI CsA during their first allogeneic HCT. Methods: A retrospective study of adult patients undergoing first allogeneic HCT at the University of Minnesota Medical Center between 2011 and 2017. Patients were grouped according to the administration method. The primary outcome was the occurrence of acute grade II-IV GVHD by day +180. Secondary outcomes included the 1-year incidence of chronic GVHD, relapse, and overall survival. Results: 42 patients intolerant of TDI CsA received CsA via CIVI for >48 hours for a median of 9 days (range, 3–32 days). CsA concentrations were similar between groups. We found no difference between the rates of grade II–IV acute (45% vs 53%, p = 0.59) or chronic (17% vs 30%, p = 0.20) GVHD or overall survival (57% vs 67%, p = 0.10). Subgroup analysis of patients that received myeloablative conditioning or umbilical cord blood did not reveal significant differences in GVHD or overall survival. Cumulative incidence of relapse was higher among the continuous infusion group (39% vs. 23%, p < 0.01). Conclusion: Due to the finding of increased risk of relapse, cyclosporine should be administered as traditional twice daily infusion unless necessary. A prospective clinical trial is needed to confirm these results.
