他の:Arm 1 Control Arm (n=70)
Intervention Name: Education and Behavioral Modification Program (EBMP) Only Intervention Description: Standardized 12-week behavioral intervention including IC/BPS disease education, bladder irritant dietary restriction guidance, timed bladder training, pelvic floor relaxation training, stress and sleep adjustment guidance.
No additional oral antidepressants, analgesics or NSAIDs permitted throughout trial.
Weekly telephone follow-up for adherence monitoring.

12-week standardized behavioral intervention without additional oral drugs, including IC/BPS disease education, bladder irritant dietary restriction, timed bladder training, pelvic floor relaxation training and sleep/stress adjustment guidance.
Weekly telephone follow-up to monitor adherence; no antidepressants or analgesics permitted throughout the study period.

実験的:Arm 2 Experimental Arm (n=70)
Intervention Name: Venlafaxine + Education and Behavioral Modification Program (EBMP) Intervention Description: Full identical EBMP intervention as control group, plus flexible-dose oral venlafaxine for 12 weeks.
Week 1 starting dose: 75mg once daily evening administration; Week3 escalate to 150mg daily if well-tolerated; Week5 maximum titration up to 225mg daily based on individual tolerance and symptom improvement.
Dose down-titration allowed for intolerable adverse events to identify individual maximum tolerated dose (MTD), maintained until week12 endpoint.
No rescue analgesic, NSAID or other antidepressant allowed during study period.
Weekly telephone follow-up to record drug compliance and adverse reactions.
|
Oral venlafaxine with flexible dose titration for 12 weeks plus standardized EBMP.
Initial dose 75mg once daily in week 1, escalate to 150mg daily at week 3, maximum up to 225mg daily based on tolerance and symptom improvement.
All participants receive identical disease education, bladder training, dietary guidance and psychological stress management training weekly.
No other antidepressants, NSAIDs or rescue analgesics are allowed during the trial.

メジャーの説明 |
時間枠 |
|---|---|---|
|
Patient Self-reported Global Response Assessment (GRA)
時間枠:12 weeks after randomization
|
Binary clinical response endpoint, defined as significant overall improvement in bladder pain and urinary symptoms versus minimal/no improvement, completed by participants at the 12-week treatment endpoint.
|
12 weeks after randomization

二次結果の測定
結果測定 |
メジャーの説明 |
時間枠 |
|---|---|---|
|
Mean Visual Analog Scale (VAS) Bladder Pain Score
時間枠:Baseline, Week 1, Week2, Week6, Week12
|
0-10 Likert scale; higher scores represent more severe bladder/pelvic discomfort.
|
Baseline, Week 1, Week2, Week6, Week12
|
|
Pelvic Pain and Urgency/Frequency (PUF) Total Score
時間枠:Baseline, Week 1, Week2, Week6, Week12
|
8-item scale total score ranging 0-40; higher scores indicate worse pelvic pain and lower urinary tract symptoms.
|
Baseline, Week 1, Week2, Week6, Week12
|
|
O'Leary-Sant ICSI + ICPI Composite Symptom Score
時間枠:Baseline, Week 1, Week2, Week6, Week12
|
ICSI (0-20) evaluates frequency, nocturia, urgency and pain; ICPI (0-16) measures symptom-related life interference.
|
Baseline, Week 1, Week2, Week6, Week12
