Oral cyclosporine A treatment is feasible after myeloablative conditioning in allogeneic hematopoietic stem cell transplantation

Summary What is known and objective The target level and route of administration of cyclosporine A (CsA) differ between transplantation centres. It is unclear whether oral CsA is sufficient to maintain target level of CsA. Case summary We retrospectively analysed data from 48 adult patients, who underwent myeloablative hematopoietic stem cell transplantation. Twenty-one patients (44%) tolerated CsA orally throughout the transplantation period without increased incidence of acute graft versus host disease(aGVHD). Low concentration of CsA in week 2 was associated with increased incidence of aGVHD. What is new and conclusion Oral administration of CsA is safe, less time-consuming and economically advantageous. Close monitoring of CsA concentration is important.
