title: Hyperkalemia associated with cyclosporine (CsA) use in bone marrow transplantation.
abstract: Two adult leukemia patients underwent allogeneic bone marrow transplantation and received cyclosporine (CsA) as part of their immunosuppressive therapy. Despite adequate kidney function, both patients developed hyperkalemia. Cyclosporine was the only pharmaceutical agent to which this electrolyte abnormality could be attributed. Although the mechanism of the hyperkalemia is unclear, it seems to be related to an aldosterone-resistant state. Cyclosporine-induced hyperkalemia is a relatively common occurrence; however, there is only a single 'case report' addressing this phenomenon in bone marrow transplantation patients. We propose both mechanisms and methods of managing CsA-associated hyperkalemia in allogeneic transplantation patients.
