Brief Summary

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a collective term referring to disorders which is characterized by lower urinary tract symptoms, including bladder pain/discomfort, frequent urination without evidence of bacterial infection. The etiology of IC/BPS is still uncertain, and most current treatment for IC/BPS are only symptoms control. Our previous study revealed Epstein-Barr virus (EBV) infection presented in the IC/BPS bladders and involved the pathogenesis. Hence, using anti-viral medication valacyclovir for the patients with IC/BPS might have clinical efficacy.

Model Details: The IC/BPS patients would be investigated for baseline clinical symptoms questionnaire including VAS, QoL, ICPI, ICSI, and OSS. All of our patients would receive open-label oral valacyclovir 500 mg twice per day for 4 weeks. We estimate to enroll 30 IC/BPS patients. The overall improvement of current therapy would be assessed with Global Response Assessment (GRA).The GRA, VAS, and any adverse effect would be investigated in the telephone interview. After the full 4 weeks treatment, the patients would be asked to back to our clinic. All symptoms questionnaire (GRA, VAS, QoL, ICPI, ICSI, and OSS) and adverse effect would be evaluated again. The patients would be asked to provide urine sample again. The primary endpoint of this study is the GRA at 4 weeks. The secondary endpoints include the changes of VAS, VAS, QoL, ICPI, ICSI, and OSS between baseline and end of the study.
