Satisfaction and adherence with immunosuppressant treatment in renal transplant patients living with a working graft.

BACKGROUND: The aim of this study was to analyze patient satisfaction and adherence in a sample of renal transplant patients living with a working allograft. METHODS: An epidemiological cross-sectional multicenter study was carried out with renal recipients who had received a transplant 6-24 months before and were undergoing immunosuppressant therapy (IT). Sociodemographic and clinical variables registered were dosage, allograft functioning, number of medications, health-related quality of life (HRQoL by SF-6D), patients' satisfaction (SAT-Q) and adherence to medication (abnormal levels of immunosuppressant in blood tests [ALIBT] and clinical impression). Relationships between those parameters were contrasted (chi-square test, Spearman correlation coefficient and Mann-Whitney U-test). Multivariate regression models (linear and logistic) were computed to analyze the factors related to patients' satisfaction and adherence to medication, respectively. RESULTS: Data from 206 patients were collected (61.2% males with a mean age of 53.35 years). Nonadherence rates (29.1% and 31.1%) were found according to clinical impression and ALIBT, respectively (chi-square = 31.810, p<0.001). Overall, global patients' satisfaction (74.000 ± 1.251) and HRQoL (0.765 ± 0.011) levels were high. Low-moderate significant associations between satisfaction and adherence to IT and HRQoL were found (p<0.01). Finally, age, vitality, allograft functioning and dosage were correlated with patient satisfaction (R2=0.174; F(1,185)=4.134; p<0.043). Number of medications (odds ratio [OR] = 0.890; 95% confidence interval [95% CI], 0.812-0.975; p=0.012), convenience domain (OR=1.037; 95% CI, 1.005-1.070; p=0.021) and clinical criteria (OR=6.135; 95% CI, 2.945-12.782; p<0.001) were associated with adherence. CONCLUSIONS: In renal transplant patients, satisfaction with IT is related to the levels of HRQoL and compliance.

Anemia control in renal transplant recipients receiving continuous erythropoietin receptor activator (C.E.R.A.) treatment: the AnemiaTrans Study.

INTRODUCTION: Continuous erythropoietin receptor activator (C.E.R.A.) effectively enables anemia control in patients with chronic kidney disease, but little information is available in renal transplant recipients. The authors aimed to evaluate the effect of C.E.R.A. under clinical practice conditions on anemia control in renal transplant recipients. METHODS: This was a multicenter, retrospective, observational study carried out in adult renal transplant patients in the immediate posttransplant period and at late posttransplant period receiving C.E.R.A. in clinical practice. Patients' data were retrieved from their medical charts at baseline and months 1, 3, and 6. RESULTS: A total of 318 evaluable patients were enrolled into the study: 32 in the immediate posttransplant period and 286 at late posttransplant period (erythropoiesis-stimulating agent [ESA]-naïve, n = 44; converting from other ESAs, n = 242). Patients in the immediate posttransplant period experienced a significant increase in hemoglobin (Hb) levels from baseline to month 1 (9.9±1.5 g/dL vs. 11.5±1.4 g/dL; P< 0.001). ESA-naïve patients showed increasing mean Hb levels from baseline to month 6 (10.1±0.7 g/dL vs. 11.7±1.0 g/dL; P < 0.001) and 94.7% achieved Hb ≥11 g/dL during the study. In patients converted from other ESAs, the percentage of patients with Hb between 11-13 g/dL was maintained from baseline to month 6 with no significant differences (61.0% vs. 62.4%). Mean monthly doses of C.E.R.A. at baseline were 134.4±56.4 µg, 81.3±28.1 µg, and 93.0±44.2 µg in immediate posttransplant, ESA-naïve, and converted patients, respectively. C.E.R.A. was well tolerated. CONCLUSION: C.E.R.A. enables anemia control in renal transplant recipients, allowing target Hb levels to be achieved and maintained with doses even below those described in the Summary of Product Characteristics.
