Adhésion thérapeutique et variation des taux sanguins des anti-calcineurines chez le patient greffé rénal

Abstract : Non-adherence (NA) is a major issue after kidney transplantation (Tx). We realized a systematic review, in which criteria related to NA were discussed. And, considering that calcineurin inhibitors (CNI) blood levels variability raises the question of NA, we tried to identify factors associated to it. 37 studies on adherence and NA in TX, published between 2009 and 2014 were reviewed. NA fluctuated from 2 to 96% and sseveral factors were related to NA: a.Young age, male, low social support, unemployed, low education b. >3 months after Tx, living donor, >6 comorbidities c. >5 drugs/d, > 2 intakes/d d. Negative beliefs and/or behaviors e. Depression and anxiety. Then, we realised a cross sectional study on a cohort of kidney recipients grafted for more than 1 year. We recorded: clinical data, data from a clinical pharmacist (CP) interview and from 6 self-reports. 408 recipients were enrolled (61.2% male, median age 54 years old). We compared 2 groups according to a coefficient of variation (CV) for CNI blood levels: CV<30% (n=302) and >30% (n=106). In univariate analysis, the distance hospital-home, cyclosporine, time since Tx, discrepancies in the reconciliation process were associated with a greater risk of CV>30%. By contrast, tacrolimus once daily conferred a lower risk of CV >30%. In multivariate analysis discrepancies remained significant (OR=3.2 CI 95% [1.21-9.01], p=0.02). ACV >30% for CNI blood levels after lyear post Tx seems to reflect NA, and could easily be confirmed by the CP interview. This could be a simple method to detect NA in clinical routine.
