Antimuscarinic Agent Treatment Affecting Patient-Reported Outcomes in Overactive Bladder Syndrome With Depressive...

We investigated improvements in overactive bladder symptoms and depressive symptoms after solifenacin treatment in overactive bladder patients with or without depressive symptoms.

We performed a prospective study of patients who had been diagnosed with overactive bladder from July 2013 to June 2014. Based on the Beck Depression Inventory questionnaire, the test subjects were divided into group 1, without depressive symptoms (0-9 points), and group 2, with depressive symptoms (10 or more points). The patients were administered 5 mg of solifenacin for 3 months. The following outcomes were analyzed at the first visit, 4 weeks, and 12 weeks: the overactive bladder symptom score (OABSS), International Prostate Symptom Score (IPSS), patients' perceptions of their bladder condition, and the Beck Depression Inventory.

A total of 72 patients participated, and 52 patients completed the study. Most outcome measures showed improvements in both groups at weeks 4 and 12. Especially in group 2, the questionnaires showed significant improvements from baseline to week 12, indicating that solifenacin was effective at treating overactive bladder symptoms (group 1 vs. group 2: OABSS, -2.67±0.80 vs. -3.00±0.77; P<0.01; IPSS-total, -2.14±2.15 vs. -4.94±1.70; P<0.01). Statistically significant decreases in the Beck Depression Inventory score from baseline to weeks 4 and 12 were observed in group 2 (group 1 vs. group 2: 1.43±0.74 vs. -2.68±4.05 at week 4, P<0.001; 0.10±3.37 vs. -5.52±5.82 at week 12, P<0.001).

In overactive bladder patients with depressive symptoms, solifenacin can help improve quality of life and depressive symptoms at the same time.
