Objective: Depressive and anxiety symptoms could affect the quality of life and prognostic outcomes in chronic kidney disease (CKD) patients, but only a few studies focus on the interventions to manage or prevent these symptoms in CKD patients. Therefore, this study was conducted to compare the efficacy and acceptability of agomelatine versus paroxetine in treating depressive and anxiety symptoms in CKD patients.
Methods: CKD stage 2–4 patients with depressive and anxiety symptoms were included. The first patient was randomized in April 2013 and the last clinic visit occurred in March 2017. The included patients were randomly assigned to receive paroxetine 20–40 mg/day or agomelatine 25–50 mg/day. The treatment was continued for 12 weeks. The Hamilton Depression Rating Scale (HDRS) (17-item) and Hamilton Anxiety Rating Scale (HARS) were the primary outcome measures, and the response rate, remission rate, and Activities of Daily Living (ADL) scale were the secondary outcome measures. Meanwhile, the adverse events were recorded during the whole treatment period.
Results: At baseline and week 4, both groups had similar average HDRS and HARS scores. But at week 8 and 12, compared to the patients receiving paroxetine, the patients receiving agomelatine had significantly lower average HDRS scores (p =0.002, p =0.001, respectively) and HARS scores (p <0.00001, p <0.00001, respectively). At week 12, the patients receiving agomelatine had a non-significantly lower average ADL score, and non-significantly higher response and remission rates. The adverse events in both groups were mild and transient.
Conclusion: These results demonstrated that the agomelatine had some advantages over paroxetine in treating CKD stage 2–4 patients with depressive and anxiety symptoms, and future studies are needed to further explore its efficacy and acceptability.
