摘要：Purpose: The aim of this study was to determine the prevalence of nonadherence in a cohort of renal transplant recipients (RTRs) and to evaluate prospectively whether more intense clinical surveillance and reduced pill number enhanced adherence. Patients and methods: The study was carried out in 310 stable RTRs in whom adherence, life satisfaction, and transplant care were evaluated by specific questionnaires (time 0). The patients under tacrolimus (TAC; bis in die [BID]) were then shifted to once-daily TAC (D-TAC) to reduce their pill burden (Shift group) and were followed up for 6 months to reevaluate the same parameters. Patients on cyclosporin or still on BID-TAC constituted a time-control group. Results: The prevalence of nonadherence was 23.5% and was associated with previous rejection episodes ( P <0.002), and was inversely related to Life Satisfaction Index, anxiety, and low glomerular filtration rate (minimum P <0.03). Nonadherent patients were significantly less satisfied with their medical care and their relationships with the medical staff. A shift from BID-TAC to D-TAC was performed in 121 patients, and the questionnaires were repeated after 3 and 6 months. In the Shift group, a reduction in pill number was observed ( P <0.01), associated with improved adherence after 3 and 6 months (+36%, P <0.05 versus basal), with no change in controls. Decreased TAC trough levels after 3 and 6 months (−9%), despite a slight increase in drug dosage (+6.5%), were observed in the Shift group, with no clinical side effects. Conclusion: The reduced pill burden improves patients' compliance to calcineurin-inhibitors, but major efforts in preventing nonadherence are needed.
