EPIGREN : une cohorte pharmaco-clinique en transplantation rénale – Objectifs, méthodes, caractéristiques des patients greffés rénaux et de leur qualité de vie

摘要

Among all existing studies/cohorts in kidney transplantation, only a few study the impact of the pharmacological parameters. In addition to the clinical file, the use of a self-administered questionnaire has been validated to collect these data. Comparison between clinical file and self-administered questionnaire concerning the reporting of adverse events highlighted some differences. Infections were the most reported adverse events by the physicians while the patients declared only a few. Adherence evaluated with the self-administered questionnaire decreased between the first and third post-transplantation year and so did the feeling of euphoria and revival. The « Mental health » dimension of the quality of life (QOL) ReTransQol score decreased over this period. However patients’ fear of losing the graft increased as shown by the decrease of the « Fear of losing the graft » dimension of the QOL score. QOL, evaluated by generic and kidney-transplanted-specific questionnaires is also an important parameter that must be considered in patient follow-up. Psychometric properties of the second version of the ReTransQol, as well as its reproducibility and its sensitivity to changes have been validated as early as the 3rd post-kidney-transplantation month. The pharmacoeconomic study Ephegren, development of Epigren cohort, will study the cost-effectiveness and cost-utility ratio of immunosuppressive and anti-cytomegalovirus strategies. Guidelines will then be proposed to standardise the treatments and decrease the management costs of kidney-transplant recipients.
