[Results of conversion from conventional immunosuppressive therapy to cyclosporin A in complications following kidney transplantation].

In 41 patients suffering from complications late after kidney transplantation the conventional immunosuppression was converted to Cyclosporin A. A complete normalization was obtained in the case of acquired immunoglobulin G deficiency and in persistent leukocytopenia. 6 patients suffering from life-threatening bacterial infections did survive after conversion with functioning allograft and 8 out of 9 late rejections were reversible. Conversion may be necessary in chronic hepatopathy and chronic rejection. A conversion to cyclosporin A is recommended because of control of complications in 78% (46/59) of the recipients.
