In this study, we explored the correlation the level of the urinary oxidative stress marker 8-hydroxy-2`-deoxyguanosine (8-OHdG) with response after antimusucarinic therapy in female patients with OAB. METHODS Urinary 8-OHdG levels were measured in 20 female patients (median 70.0 years old) with OAB. Patients were treated with solifenacin 5 mg once a daily. Urine samples were collected before, 1 and 3 months after treatment. Evaluations included International Prostate Symptom Score (IPSS), QOL index and Overactive Bladder Symptom Score (OABSS) before and 1, 3 months after treatment. Effects on bladder function was evaluated before and 3 months after treatment by filling cystometry. Urinary 8-OHdG levels were measured by enzyme-linked immunosorbent assay technique (ELISA) and the results were normalized based on creatinine (Cr) concentration. A p value of less than 0.05 was considered statistically significant. RESULTS Average IPSS, QOL index, OABSS were significantly improved from 16.0, 5.3, and 10.1 at baseline to 9.3, 3.0, and 5.9 at 1 month, to 7.4, 2.4, and 5.1 at 3 months after treatment. Urinary 8-OHdG levels did not decrease from 11.8±5.7 ng/mg Cr at baseline to 12.2±6.2 ng/mg Cr at 1 month (p=0.556), but significantly decreased from baseline to 7.9±3.8 ng/mg Cr at 3 month (p=0.0464) after treatment. As to cystmetric findings, volume of first desire to void and maximum cystometric capacity significantly increased from 114±41.7ml, 279±95.0 ml at baseline to 151±38.9 ml, 316±79.7 ml at 3 months, respectively. CONCLUSIONS Solifenacin treatment was subjectively and objectively effective for female OAB patients. The urinary 8-OHdG levels significantly decreased after antimuscarinic therapy with solifenacin. It could provide important information on clinical significance between oxidative stress and OAB. © 2013 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 189Issue 4SApril 2013Page: e759 Advertisement Copyright & Permissions© 2013 by American Urological Association Education and Research, Inc.MetricsAuthor Information Teruhiko Yokoyama Kurashiki, Japan More articles by this author Shinjiro Shimizu Kurashiki, Japan More articles by this author Kazuhiko Fukumoto Kurashiki, Japan More articles by this author Yoshiyuki Miyaji Kurashiki, Japan More articles by this author Atsushi Nagai Kurashiki, Japan More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
