Young age and tobacco use are predictors of lower medication adherence in inflammatory bowel disease.

BACKGROUND: Medication adherence is crucial in the management of patients with inflammatory bowel disease (IBD) because medication nonadherence in these patients is associated with an increased risk of flare-up, relapse, recurrence, loss of response to anti-tumour necrosis factor agents, morbidity and mortality, and poor quality of life. Data on risk factors are very controversial in the literature. AIM: To assess the prevalence of medication nonadherence and to identify predictors of low medication adherence in Spanish patients with IBD. PATIENTS AND METHODS: We carried out a cross-sectional study that included consecutive outpatients with IBD attending in our adult tertiary clinic in a 3-month period. Morisky 8-Item Medication Adherence Scale questionnaire as well as a survey of sociodemographic data were used. RESULTS: A total of 181 patients were evaluated. Almost half of the patients (46.4%) had high medication adherence, 30.9% had medium adherence, and 22.7% had low adherence. In relation to predictive factors of medication adherence, multivariate analysis showed that age was associated with high adherence [odds ratio (OR): 1.04; 95% confidence interval (CI): 1.01-1.06; P=0.002]. However, being a smoker and presence of Crohn's disease were associated with low adherence (OR: 3.47; 95% CI: 1.36-8.90; P<0.01 and OR: 2.54; 95% CI: 1.12-5.79; P<0.05, respectively). CONCLUSION: Only half of patients were high medication adherers. Young age, active smoking, and Crohn's disease seems to be predictors of low medication adherence. On the basis of these data, efforts for reinforce medication adherence should be especially directed to young patients and smokers.

Real-World Multicenter Experience of Immunosuppression Minimization Among 661 Liver Transplant Recipients.

BACKGROUND Long-term morbidity and mortality in liver transplant recipients is frequently secondary to immunosuppression toxicity. However, data are scarce regarding immunosuppression minimization in clinical practice. MATERIAL AND METHODS In this cross-sectional, multicenter study, we reviewed the indications of immunosuppression minimization (defined as tacrolimus levels below 5 ng/mL or cyclosporine levels below 50 ng/mL) among 661 liver transplant recipients, as well as associated factors and the effect on renal function. RESULTS Fifty-three percent of the patients received minimized immunosuppression. The median time from transplantation to minimization was 32 months. The most frequent indications were renal insufficiency (49%), cardiovascular risk (19%), de novo malignancy (8%), and cardiovascular disease (7%). The factors associated with minimization were older age at transplantation, longer post-transplant follow-up, pre-transplant diabetes mellitus and renal dysfunction, and the hospital where the patients were being followed. The patients who were minimized because of renal insufficiency had a significant improvement in renal function (decrease of the median serum creatinine level, from 1.50 to 1.34 mg/dL; P=0.004). Renal function significantly improved in patients minimized for other indications, too. In the long term, glomerular filtration rate significantly decreased in non-minimized patients and remained stable in minimized patients. CONCLUSIONS Immunosuppression minimization is frequently undertaken in long-term liver transplant recipients, mainly for renal insufficiency. Substantial variability exists regarding the use of IS minimization among centers.
