Evaluation of the efficacy of Vesusten® in patients with overactive bladder and chronic recurrent cystitis
Abstract
Introduction. Numerous studies have suggested that lower urinary tract infections may be involved in the development of overactive bladder (OAB) in patients who are resistant to standard treatment. In these cases, treatment targeting all stages of disease progression could be beneficial.Objective. To evaluate the efficacy of Vesusten® in management of OAB in women with chronic recurrent cystitis.Materials & methods. The study involved 40 patients diagnosed with OAB and chronic recurrent cystitis. All patients received Vesusten® as therapy for OAB. They received 5 mg of the medication intramuscularly three times per week for a total of 10 doses. The study included three stages: a screening period lasting up to 14 days; the stage for assessing the effectiveness of therapy (42 days from the start of therapy, including the therapy period + further follow-up after the end of therapy); follow-up period — 180 days + 14 days from completion of treatment.Results. It was revealed Vesusten® clinical effectiveness on the severity of OAB symptoms and the quality of life of patients. hree weeks after the end of treatment, there was a statistically significant decrease in the severity of OAB symptoms on the Patient Perception Index of Urgency and Symptoms (PPIUS) (2.2 ± 1.0 vs 0.95 ± 1.0 points) and TUFS (28.4 ± 11.6 vs 5. 1 ± 6.4 points), a decrease in the number of urinations during the day (11.5 ± 2.2 vs 8.8 ± 2.7 episodes) and at night (3.5 ± 1.8 vs 1.4 ± 1.5 episodes) time (p < 0.001). The nighttime urination frequency decreased by more than 2.5 times, while the proportion of patients who did not wake up at night for urination increased from 10 % to 35%. Evaluation of the Overactive Bladder Questionnaire (OAB-Q) after the completion of treatment compared with the initial data showed a statistically significant improvement in quality of life related to the severity of OAB symptoms (24.8 ± 7.5 vs 15.7 + 6.4 points; p < 0.001), and with general health status (74.0 ± 31.7 vs 57.6 ± 22.1 points; p = 0.0087). The average duration of the relapse-free period, including the course of Vesusten® treatment and the follow-up period, significantly increased to 42.90 ± 9.64 weeks in comparison with the duration of the relapse-free period before patients’ inclusion in the study — 17.96 ± 7.75 weeks (p < 0.001). During the clinical study, eight women experienced exacerbations of chronic cystitis (20%).Conclusion. Study results suggest that the drug Vesusten® may be an effective treatment for OAB in combination with chronic recurrent cystitis. Based on our findings, we believe that Vesusten® can be considered as a potential treatment option for patients with chronic cystitis.
