Venlafaxine Combined With Education and Behavioral Intervention for Bladder Pain Syndrome

This study aims to compare two treatment plans for adults with bladder pain syndrome (also called interstitial cystitis), a disease that causes long-lasting bladder pain, frequent urination and urgent need to pee. All participants will receive standardized patient education and behavioral training to relieve urinary discomfort. Half of the participants will only get this behavioral intervention, while the other half will take oral venlafaxine in addition to the same behavioral training for 12 weeks. We will check patients' pain levels, urination frequency, sleep quality, mood and daily life ability at 1, 2, 6 and 12 weeks of treatment. The main goal is to see whether adding venlafaxine can better ease bladder pain and urinary symptoms without obvious side effects. This research will provide safer and more effective treatment suggestions for patients with bladder pain syndrome.

Investigation of PEMF Therapy for Female Patients With IC/BPS

The purpose of this study is to gather information about the safety and effectiveness of the non-pharmacological (non-drug), non-invasive treatment known as low-frequency pulsed electromagnetic field (PEMF) therapy. The study team will distribute the PEMF device to female adults with Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) to measure its ability to decrease bladder and pelvic pain as well as other urinary symptoms associated with IC/BPS. There are two sequential Aims in this study and subjects will be recruited to participate in only one Aim. In both Aims, data will be collected at baseline/enrollment, 4-weeks after using PEMF therapy, and 8, 12, and 16 weeks post-enrollment.

New Approaches to Nerve Stimulation Therapy for Bladder Pain Syndrome

Many women suffer from bladder pain syndrome (BPS). There are many treatments, but there is no one universally effective option. The goal of this clinical trial is to explore the use of electrical energy directed towards a group of nerves, called the superior hypogastric plexus, for treatment of BPS in women over the age of 18 with a diagnosis of BPS. The main question it aims to answer is: does use of electrical micro-current directed at the superior hypogastric plexus improve pain associated with BPS? There is data from many different studies that suggest that this kind of therapy might provide relief of BPS symptoms. Participants will be asked to participate for a total of six months from the date of their first nerve treatment. At the first appointment, they will be evaluated in the Walter Reed Chronic Pain clinic and asked several questions about the severity and personal management of their symptoms. The procedure will then be performed by inserting two needles into the back (one on either side of the spine) and directing extremely short bursts of electrical micro-current towards the target nerve. The medical term for this is "pulsed radiofrequency ablation." This procedure causes disruption on a microscopic level of nerve fibers that send pain sensations to the bladder and other organs in the pelvis. Following this initial appointment, participants will be asked about their symptoms at 1-, 3-, and 6-month follow-up appointments. Participants will be asked about pain, mood symptoms, sexual function, and measures of bladder irritation. The procedure will only be performed once. At the study conclusion, researchers will analyze pain scores, as well as other secondary outcomes listed above. Benefits of this study may include possible relief of BPS symptoms. This may help to advance research about treatments for BPS. This is a novel approach to the treatment of BPS and as such may provide benefits greater than those found in treatment outside of the study.

Efficacy of Pulsed Electromagnetic Field and Heparin/Bupivacaine Instillations

The objective of this study is to test the idea that Pulsed Electromagnetic Field (PEMF) therapy will serve as a safe therapeutic modality that can effectively be administered simultaneously with bladder instillations of a bupivacaine-heparin cocktail to improve the chronic pain and/or associated symptoms of Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) patients. The study team will distribute the PEMF device to female adults with IC/BPS who have been prescribed bladder instillations of bupivacaine-heparin to see if PEMF therapy in conjunction with bladder instillations of heparin and bupivacaine may be more effective in reducing pain levels and symptomatology of IC/BPS than instillations alone.

EPPIC: Easing Pelvic Pain Interventions Clinical Research Program

The EPPIC (Easing Pelvic Pain Interventions Clinical Research Program) study evaluates an ultra-brief, 4 session cognitive behavioral pain treatment transdiagnostic in design for urologic chronic pain syndrome (UCPPS) with clinical and practical advantages over existing behavioral therapies whose length and focus limits their adoption by clinicians and coverage for mechanistically similar comorbidities. A theoretically informed, practical, empirically grounded approach will systematically unpack CBT's working mechanisms, clarify for whom it works, ease dissemination, appeal to patients, providers, payers, and policy makers in the COVID-19 era favoring low resource intensity treatments, and reduce cost and inefficiencies associated with high intensity therapies whose complexity, length, and scarcity restricts uptake and impact.

Pain Type and Interstitial Cystitis/Bladder Pain Syndrome Treatment

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a severe pain condition affecting 3-8 million people in the United States lacking treatments that work. Emotional suffering is common in IC/BPS and known to make physical symptoms worse, and studies show patient sub-groups respond differently to treatment. Individuals with IC/BPS have distinct subgroups, or "phenotypes," largely characterized by the distribution of pain throughout the body. Supported by our preliminary evidence, the overall goal of this project is to assess how IC/BPS phenotype may affect response to two different therapies often given without regard to patient phenotype, pelvic floor physical therapy (PT) and cognitive-behavioral therapy (CBT) for IC/BPS.

Identifying Genetic Causes of IC/BPS

Interstitial cystitis (IC), also called Bladder Pain syndrome (BPS) is a common condition with no known cause or cure. Twin studies and family accounts have suggested that the condition may be genetic or passed down (inherited) from one generation to another. In this study, the investigators are collecting genetic material via blood or saliva and medical information from families in North America in an attempt to identify genetic factors that may cause IC/BPS. The investigators are enrolling inviduals with IC/BPS and their family members (family members with and without IC like symptoms). Travel to Boston not required.

Bladder Botox UTI Antibiotic Prophylaxis

Overactive bladder (OAB) is a common condition with a prevalence of 17% in the general population that significantly affects quality of life. Intradetrusor onabotulinumtoxinA injections are an advanced therapy for OAB as well as interstitial cystitis/bladder pain syndrome (IC/BPS). The most common adverse event following intradetrusor injection of onabotulinumtoxinA in urinary tract infection (UTI), which occurs in 8.6-48.1% of patients. To prevent UTIs, patients are given a course of antibiotics, however the ideal prophylactic regimen has not been determined for the timing, duration, and type of antibiotic. Four retrospective studies in the literature address this question with variable conclusions, and there are no prospective studies. Identifying the ideal regimen is important for preventing UTIs as well as minimizing antibiotic use to prevent adverse effects and development of antibiotic resistance. The population to be studied will be female patients 18 years and older who are patients of the urogynecology and urology clinics at Walter Reed National Military Medical Center with a diagnosis of OAB or IC/BPS and have chosen to be treated with intradetrusor onabotulinumtoxinA injections. It will be a non-blinded randomized controlled noninferiority trial in which the patients are randomly placed into 2 groups. The first group will receive a 3 day course of twice daily oral nitrofurantoin 100mg starting at the time of the procedure, and the second group will receive a single dose of 100mg oral nitrofurantoin at the time of the procedure. The patients will be screened at the clinic at the time that they schedule their intradetrusor onabotulinumtoxinA injection appointment or by phone 1-2 weeks prior to their procedure. If the patient agrees to participate in the study then they will be instructed to give a urine sample for urinalysis and culture 1 week prior to the procedure appointment to exclude existing UTI. If a UTI is diagnosed at this time they must complete treatment prior to the procedure or will need to reschedule their procedure. On the day of the procedure patients will receive the clinic standard 10ml of 2% viscous lidocaine through the urethra 10-20 minutes prior to the procedure, and may be offered 5-10mg oral diazepam at the discretion of the treating physician. All patients will be given 200mg of phenazopyridine and 100mg of nitrofurantoin prior to the initiation of the procedure. The procedure will take place as directed by the treating physician per standard operating procedure. A urinalysis and urine culture will be placed for all study participants at time of their procedure appointment in case they have symptoms of UTI, and they will be instructed to follow up with the research team by phone if they have concerns for a UTI. Patients will be contacted 30-45 days after the procedure by phone, email, or message through genesis and asked about any UTI symptoms, UTI diagnoses and secondary outcomes during the 30 days following the procedure. Data will be analyzed for the primary outcome of UTI rates in the 30 days following intradetrusor onabotulinumtoxinA injection.

Evaluating the Efficacy and Patient Experience of Catheter-Free Intravesical Instillation

This study aims to evaluate a catheter-free method for delivering medications directly into the bladder, known as intravesical instillation, which is commonly used to treat conditions such as interstitial cystitis/bladder pain syndrome (IC/BPS), recurrent urinary tract infections, bladder cancer, and post-chemotherapy or post-radiation cystitis. The study investigates whether this method, which eliminates the need for catheterization, reduces discomfort and complications while maintaining treatment effectiveness. By collecting data on patient experiences and outcomes, the study seeks to determine if this approach provides a safer and more comfortable alternative to traditional catheter-based treatments.

Effect of Intradetrusor onabotulinumtoxinA Injection Versus Conservative Management on Female Sexual Function in Patients With Bladder Pain Syndrome

Interstitial cystitis/bladder pain syndrome (IC/BPS) is estimated to affect 3.3 to 7.9 million women aged 18 years and older in the United States. The American Urological Association (AUA) defines IC/BPS as "an unpleasant sensation (pain, pressure, discomfort) perceived to be related to the urinary bladder, associated with lower urinary tract symptoms of more than six weeks duration, in the absence of infection or other identifiable causes". IC/BPS significantly impacts quality of life, with the individual domains of sexual function, anxiety and depression, sleep quality and work productivity being specifically affected. Significant sexual dysfunction in women with IC/BPS has been consistently demonstrated across multiple international studies, with a prevalence ranging from 68% to 91%. In fact, among all patients with lower urinary tract symptoms, patients with a diagnosis of IC/BPS had the highest levels of impaired sexual function, mostly due to dyspareunia. Recommended treatments for IC/BPS include dietary and behavioral modifications, oral medications, bladder instillations, bladder hydrodistension, intradetrusor injection of onabotulinumtoxinA and major surgery. Scant research exists on how treating IC/BPS affects sexual function. We are conducting a prospective cohort study to assess for improvement in sexual function following intravesical onabotulinumtoxinA injection versus conservative management for IC/BPS. The study will consist of three groups: intradetrusor onabotulinumtoxinA injection, conservative management and age-matched, healthy controls. All patients aged 18 years and older presenting to the Walter Reed National Military Medical Center (WRNMMC) Urogynecology clinic who are given a diagnosis of IC/BPS and have an O'Leary Sant index questionnaire scoring 13 or greater will be eligible for the study. The primary study outcome is change in the pre- and 12-week post-treatment Female Sexual Function Index (FSFI). The secondary outcomes will include changes in the pre- and post-treatment O'Leary Sant index, Patient Global Impression of Improvement (PGI-I), Patient Global Impression of Severity (PGI-S), Pelvic Organ Prolapse/Incontinence Sexual Questionnaire, IUGA-Revised (PISQ-IR), Visual analog pain scale and 24-hour bladder diary (number of daily voids, number of nightly voids, incontinence episode). Adverse events will be monitored, including urinary tract infection or need for urinary catheterization due to urinary retention within 12 weeks of start of treatment. The age-matched, healthy control group will complete only one set of questionnaires to serve as a baseline comparison to the IC/BPS groups. For between-groups comparisons, a sample size of 49 per group will have 80% power to detect a clinically important difference of 4 points if the standard deviation is 7 points, assuming a 5% two-sided significance level. We will therefore recruit 55 subjects per group to allow for approximately 10% attrition between the pre- and post-treatment assessments. This study will be powered to detect a difference between treatments groups, which has not yet been reported in the literature.

EA for BPS: An RCT and Study for Central Mechanism

This is a randomized controlled and assessor-blinded design trial to evaluate the efficacy and safety of acupuncture for bladder pain syndrome(BPS). All eligible participants will be randomly assigned to the medication group(n=21), EA group(n=42) and SA group(n=21) in a 1:2:1 allocation ratio. Participants will receive 4-week treatments phase followed by a 4-week follow-up phase. Outcomes will be assessed at baseline, during the treatment and at the end of the follow-up. Outcome assessors, data managers and statisticians will be blinded to the group allocation, while acupuncturists and participants will not be blinded for obvious reasons. Besides, fMRI will be used to collect spontaneous electrical activity of the brain of patients. In this trial, the investigators assume that electroacupuncture for BPS, compared to amitriptyline, is instrumental in improving symptoms such as pain, frequent micturition and emotional disorder.
