The effect of immunosuppressive drugs on quality of life after renal transplantation.

This prospective, randomized study investigates the effect of two immunosuppressive treatment regimens on quality of life after renal transplantation. At 3 months after transplantation, patients treated with cyclosporine (CsA) and prednisone (Pred) were allocated to either withdrawal of Pred (n = 60) or to conversion of CsA to azathioprine (Aza) (Aza-Pred, n = 60). Quality of life was evaluated just before randomization, and at 6 and 12 months after transplantation using the Sickness Impact Profile (SIP), the Affect Balance Scale (ABS), the Center for Epidemiological Studies Depression Scale (CES-D), measures of satisfaction with several domains of life experience, and a population-specific physical symptoms questionnaire. In both groups, the overall SIP score as well as the scores on its physical and psychosocial dimensions improved continuously after transplantation, reaching levels that are comparable to those found in the general population. The occurrence of acute or chronic rejection had a significantly negative effect on SIP and CES-D scores. Intention-to-treat analysis showed no differences between groups for scores on SIP, ABS, CES-D, and satisfaction measures. Exclusion of 41 patients who did not strictly adhere to their originally designated therapy showed a tendency for better psychosocial SIP scores in CsA patients (P = 0.05), which mainly resulted from a difference on the category of social interaction (P = 0.01). This difference occurred despite a similar rejection rate and worse renal function in CsA-treated patients. Shortly after steroid withdrawal, a high proportion of CsA patients complained of stiff or painful muscles (CsA: 74%, Aza-Pred: 36%; P = 0.002). Our data indicate that if successfully completed, CsA monotherapy from 3 months after transplantation may lead to a higher degree of psychosocial well-being as compared with conversion from CsA-Pred to Aza-Pred. It seems likely that this advantage is related to the withdrawal of Pred.
