Urologic Chronic Pelvic Pain Syndrome Flares: A Comprehensive, Systematic Review and Meta-Analysis of the Peer-Reviewed Flare Literature. J Urol 2024; 211:341-353. [PMID: 38109700 PMCID: PMC11037930 DOI: 10.1097/ju.0000000000003820] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Accepted: 12/07/2023] [Indexed: 12/20/2023]
Abstract
PURPOSE We sought to systematically review and summarize the peer-reviewed literature on urologic chronic pelvic pain syndrome flares, including their terminology, manifestation, perceived triggers, management and prevention strategies, impact on quality of life, and insights into pathophysiologic mechanisms, as a foundation for future empirical research. MATERIALS AND METHODS We searched 6 medical databases for articles related to any aspect of symptom exacerbations for interstitial cystitis/bladder pain syndrome and chronic prostatitis/chronic pelvic pain syndrome. A total of 1486 abstracts and 398 full-text articles were reviewed, and data were extracted by at least 2 individuals. RESULTS Overall, we identified 59 articles, including 36 qualitative, cross-sectional, or case-control; 15 cohort-based; and 8 experimental articles. The majority of studies described North American patients with confirmed diagnoses. "Flare" was a commonly used term, but additional terminology (eg, exacerbation) was also used. Most flares involved significant increases in pain intensity, but less data were available on flare frequency and duration. Painful, frequent, long-lasting, and unpredictable flares were highly impactful, even over and above participants' nonflare symptoms. A large number of perceived triggers (eg, diet, stress) and management/prevention strategies (eg, analgesics, thermal therapy, rest) were proposed by participants, but few had empirical support. In addition, few studies explored underlying biologic mechanisms. CONCLUSIONS Overall, we found that flares are painful and impactful, but otherwise poorly understood in terms of manifestation (frequency and duration), triggers, treatment, prevention, and pathophysiology. These summary findings provide a foundation for future flare-related research and highlight gaps that warrant additional empirical studies.

Abstract
AIM To explore the life experiences of women with interstitial cystitis. DESIGN A qualitative phenomenological study. METHODS Fifteen women with interstitial cystitis were recruited from a regional hospital in Taiwan using purposive sampling. Data were collected via one-on-one semistructured interviews and analysed using the Colaizzi's method. Rigorous testing was conducted to identify the themes and subthemes. RESULTS Four major themes were identified: torment, restriction, acceptance and empowerment. These themes reflect the life experiences of women with interstitial cystitis. They endured unrelenting physical and psychological distress and loneliness, experienced obstacles and limitations in daily living because of their symptoms, accepted reality and considered their symptoms as a part of everyday life and developed coping skills for the disease. CONCLUSION Medical care, psychological support and emotional venting are crucial for women with interstitial cystitis. Despite living a life full of frustrations and suffering caused by the unpredictable and unrelenting nature of interstitial cystitis, through external support and intrinsic positive cognitive reconstruction, women with interstitial cystitis gradually accepted that they were ill. They adapted to their situation, developed a suitable lifestyle and pace and ultimately achieved stable coexistence with the disease. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE Although women with interstitial cystitis are affected by an incurable disease, through adequate assistance and reconstruction of perception, they can develop coping skills and stably coexist with their disease. There is a delicate dynamic balance between their lives and disease. IMPACT This study may help clinicians to understand patients' life experiences and provide suitable care. This may improve the quality of care provided to women with interstitial cystitis and help them adapt to their disease, thereby improving their life satisfaction. REPORTING METHOD This study was reported according to the COREQ checklist. PATIENT OR PUBLIC CONTRIBUTION Women with interstitial cystitis contributed to the study data.

Abstract
OBJECTIVES Little is known about the impact of the COVID-19 pandemic on interstitial cystitis/bladder pain syndrome (IC/BPS). We aim to compare the number of newly diagnosed IC/BPS cases and number of patients with flares prior to and during the pandemic. METHODS We conducted a retrospective cohort study of women ≥18 years who were diagnosed with or treated for IC/BPS between March 2019 and March 2021 at an academic, urban, multisite urogynecology practice. The primary outcome was the number of IC/BPS cases from March 1, 2019 to February 29, 2020 (pre-pandemic) compared with March 1, 2020 to February 28, 2021 (during pandemic). The secondary outcome was the number of patients with flares during those same two time periods. Demographic and clinical characteristics were compared using nonparametric tests and interrupted time series (ITS) was used to evaluate our outcomes of interest. p-Value <.05 was considered significant. RESULTS Fifty-four women (4.87% of new patients) were diagnosed with IC/BPS during the pandemic compared with 40 women pre-pandemic (4.05% of new patients). The median age was 35.0. Seventy-two percent were premenopausal, 75% sexually active, and 31% had anxiety, and there were no significant differences between groups. Although the number of patients newly diagnosed with IC/BPS was higher during the pandemic, the diagnosis rates between time periods were not statistically different. Thirty-five patients experienced flares during the pandemic compared with 49 patients the year prior (p = .43). This difference was also not statistically significant on ITS analysis. CONCLUSIONS Although more patients were diagnosed with IC/BPS during versus before the pandemic, the difference in diagnosis rates was not different between these periods.

Abstract
Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) is a chronic disorder characterized by pelvic and/or bladder pain, along with lower urinary tract symptoms that have a significant impact on an individual's quality of life. The diverse range of symptoms and underlying causes in IC/BPS patients pose a significant challenge for effective disease management and the development of new and effective treatments. To facilitate the development of innovative therapies for IC/BPS, numerous preclinical animal models have been developed, each focusing on distinct pathophysiological components such as localized urothelial permeability or inflammation, psychological stress, autoimmunity, and central sensitization. However, since the precise etiopathophysiology of IC/BPS remains undefined, these animal models have primarily aimed to replicate the key clinical symptoms of bladder hypersensitivity and pain to enhance the translatability of potential therapeutics. Several animal models have now been characterized to mimic the major symptoms of IC/BPS, and significant progress has been made in refining these models to induce chronic symptomatology that more closely resembles the IC/BPS phenotype. Nevertheless, it's important to note that no single model can fully replicate all aspects of the human disease. When selecting an appropriate model for preclinical therapeutic evaluation, consideration must be given to the specific pathology believed to underlie the development of IC/BPS symptoms in a particular patient group, as well as the type and severity of the model, its duration, and the proposed intervention's mechanism of action. Therefore, it is likely that different models will continue to be necessary for preclinical drug development, depending on the unique etiology of IC/BPS being investigated.

Abstract
Symptom exacerbation due to stress is prevalent in many disease states, including functional disorders of the urinary bladder (e.g., overactive bladder (OAB), interstitial cystitis/bladder pain syndrome (IC/BPS)); however, the mechanisms underlying the effects of stress on micturition reflex function are unclear. In this study we designed and evaluated a stress-induced symptom exacerbation (SISE) mouse model that demonstrates increased urinary frequency and somatic (pelvic and hindpaw) sensitivity. Cyclophosphamide (CYP) (35 mg/kg; i.p., every 48 hours for a total of 4 doses) or 7 days of repeated variate stress (RVS) did not alter urinary bladder function or somatic sensitivity; however, both CYP alone and RVS alone significantly (p ≤ 0.01) decreased weight gain and increased serum corticosterone. CYP treatment when combined with RVS for 7 days (CYP+RVS) significantly (p ≤ 0.01) increased serum corticosterone, urinary frequency and somatic sensitivity and decreased weight gain. CYP+RVS exposure in mice significantly (p ≤ 0.01) increased (2.6-fold) voiding frequency as we determined using conscious, open-outlet cystometry. CYP+RVS significantly (p ≤ 0.05) increased baseline, threshold, and peak micturition pressures. We also evaluated the expression of NGF, BDNF, CXC chemokines and IL-6 in urinary bladder in CYP alone, RVS alone and CYP+RVS mouse cohorts. Although all treatments or exposures increased urinary bladder NGF, BDNF, CXC and IL-6 content, CYP+RVS produced the largest increase in all inflammatory mediators examined. These results demonstrated that CYP alone or RVS alone creates a change in the inflammatory environment of the urinary bladder but does not result in a change in bladder function or somatic sensitivity until CYP is combined with RVS (CYP+RVS). The SISE model of CYP+RVS will be useful to develop testable hypotheses addressing underlying mechanisms where psychological stress exacerbates symptoms in functional bladder disorders leading to identification of targets and potential treatments.

Abstract
INTRODUCTION There has been a sparse exploration of the lived experience of men with urologic chronic pelvic pain syndrome (UCPPS), and none with the goal of Investigating the experience of "flares" as part of this chronic pain syndrome in men. METHODS We conducted three focus groups of male UCPPS patients at two sites of the MAPP Research Network (n = 16 total participants) to explore the full spectrum of flares and their impact on men's lives. RESULTS Flare experiences were common and specific symptom components varied widely. Men reported nonpelvic symptoms (e.g., diarrhea), and variability in symptom intensity (mild to severe), duration (minutes to days), and frequency of flares. Flares episodes, and the threat of flares, were disruptive to their lives, social roles, and relationships. Distinct long-term impacts were reported, such as decreased sexual activity, decreased travel, and potential loss of employment or career. The themes included social isolation and the need for a sense of control and understanding over their unpredictable symptoms. CONCLUSIONS Given their negative impact, future research with men and UCPPS should focus on approaches to prevent flares, and should consider a multimodal approach to reducing the frequency, severity, and/or duration. Quality of life may be improved by providing men with a sense of control over their symptoms and offering them multimodal treatment options, consistent with the recommendations for further research for women with UCPPS.

Abstract
This report describes methodological and exploratory investigations of the zymosan-induced neonatal bladder inflammation (NBI) model of interstitial cystitis/bladder pain syndrome (IC/BPS) in female rats. These results validate and extend the currently employed model by evaluating critical timepoints for obtaining treatment effects and identified that a second insult as an adult including repeat intravesical zymosan, intravesical lipopolysaccharide, acute footshock stress, neuropathic nociception (facial) or somatic inflammation (hindpaw) all resulted in magnified visceromotor responses to urinary bladder distension (UBD) in rats which had experienced NBI when compared with their controls. NBI also resulted in increased tone and reactivity of pelvic floor musculature to UBD, as well as increased responsiveness to intravesical potassium chloride solutions, abnormal anxiety measures (elevated plus maze) and an increased number of submucosal petechial hemorrhages following 30 min of hydrodistension of the bladder. These phenotypic findings have correlates to the clinical features of IC/BPS in humans and so support use of this model system to examine mechanisms of and treatments for IC/BPS.

Abstract
BACKGROUND To describe the oral treatments people living with interstitial cystitis/bladder pain syndrome (IC/BPS) are using to treat their urologic condition in the UK. METHOD A questionnaire hyperlink encompassing current and previous medications taken for IC/BPS with other sociodemographic and diagnostic indices was available to the Bladder Health UK website. Interested and fully consented individuals accessed and completed the survey. RESULTS A total of 601 accessed the questionnaire of whom 173 participants responded (response rate: 28.7%) with a mean ± SD O'Leary/Sant scores of 20.12 ± 9.38. A sample size of 171 was estimated to be used in the survey. A fifth of the participants were not on any treatment at all. Amitriptyline was the most prevalent medication in use both alone and in combination. A shift in the use of unapproved (for IC/BPS) antidepressant, smooth muscle relaxant, opioids, gabapentenoids, and antibiotics was observed in the sample. There were no significant differences between the mean (SD) O'Leary/Sant scores of cohorts currently taking oral medications and those not taking it. More than two-thirds of the participants had been diagnosed with the disease more than 5 years. Just under a half (47.4%) of participants reported a history of allergy. CONCLUSION Our study provides contemporary evidence that the treatments used for managing IC/BPS encompass a broad range of medications both recommended and not recommended by current guidelines. The latter suggests patients are willing to try novel treatments when more conventional ones are ineffective.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic disease characterized by suprapubic pain and lower urinary tract symptoms. Perhaps because of the heterogeneous nature of this disease and its multifactorial etiology, clinical trials in allinclusive populations of IC/BPS patients without phenotyping in the last decade have mainly failed to discover new therapeutic modalities of IC/BPS. Thus, phenotyping IC/BPS, aimed at identifying bladder-centric and/or bladder-beyond pathologies, including cystoscopic observation of Hunner or non-Hunner lesions of the bladder mucosa, is particularly important for the future of IC/BPS management. Based on recent discussions at international conferences, including the International Consultation on IC, Japan, it has been proposed that Hunner-lesion IC should be separated from other non-Hunner IC/BPS because of its distinct inflammatory profiles and epithelial denudation compared with non-Hunner IC/BPS. However, there are still no standard criteria for the diagnosis of Hunner lesions other than typical lesions, while conventional cystoscopic observations may miss atypical or small Hunner lesions. Furthermore, diagnosis of the bladder-centric phenotype of IC/BPS requires confirmation that identified mucosal lesions are truly a cause of bladder pain in IC/BPS patients. This review article discusses the current status of IC/BPS pathophysiology and diagnosis, as well as future directions of the proper diagnosis of bladder-centric IC/BPS, in which pathophysiological mechanisms other than those in inflammatory pathways, such as angiogenic and immunogenic abnormalities, could also be involved in both Hunner-lesion IC and non-Hunner IC/BPS. It is hoped that this new paradigm in the pathophysiological evaluation and diagnosis of IC/BPS could lead to pathology-based phenotyping and new treatments for this heterogeneous disease.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) negatively affects the quality of life. In this study, we investigated the lifestyle behavioral changes patients with IC/BPS make to cope with their symptoms. This prospective study was conducted between August 2018 and June 2019. All patients had a primary symptom of suprapubic pain with a full bladder and other lower urinary tract symptoms for more than 6 weeks as well as cystoscopic findings. All participants completed our self-developed questionnaire, which included informations about their living and work environment, occupational garments, dietary habits, and personal habits. Continuous variables were compared using an independent sample t test, and categorical variables were compared using a chi-square test. We recruited 86 patients with IC/BPS and age-matched 86 controls without IC/BPS. In our study, patients with IC/BPS had more cranberry intake (45.34% vs. 5.81%, P < 0.05) than non-IC/BPS controls; the IC/BPS group had decreased consumption of coffee and spicy food; and wore less makeup or special work garments. In conclusion, patients with IC/BPS tend to make several lifestyle behavioral changes to cope with their symptoms.

Abstract
BACKGROUND To investigate whether meteorological factors (temperature, barometric pressure, relative humidity, ultraviolet index [UVI], and seasons) trigger flares in male and female urologic chronic pelvic pain patients. METHODS We assessed flare status every 2 weeks in our case-crossover study of flare triggers in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain 1-year longitudinal study. Flare symptoms, flare start date, and exposures in the 3 days preceding a flare or the date of questionnaire completion were assessed for the first three flares and at three randomly selected nonflare times. We linked these data to daily temperature, barometric pressure, relative humidity, and UVI values by participants' first 3 zip code digits. Values in the 3 days before and the day of a flare, as well as changes in these values, were compared to nonflare values by conditional logistic regression. Differences in flare rates by astronomical and growing seasons were investigated by Poisson regression in the full study population. RESULTS A total of 574 flare and 792 nonflare assessments (290 participants) were included in the case-crossover analysis, and 966 flare and 5389 nonflare (409 participants) were included in the full study analysis. Overall, no statistically significant associations were observed for daily weather, no patterns of associations were observed for weather changes, and no differences in flare rates were observed by season. CONCLUSIONS We found minimal evidence to suggest that weather triggers flares, although we cannot rule out the possibility that a small subset of patients is susceptible.

Abstract
BACKGROUND This paper summarises the discussion in a think tank at the International Consultation on Incontinence-Research Society (ICI-RS) 2018 about the treatment of bladder pain syndrome. AIMS To review the treatments of bladder pain syndrome from behavioural treatments to surgical interventions. MATERIALS AND METHODS Review the literature in the light of the think tank discussions. RESULTS All guidelines recommend different levels of treatment starting with conservative behavioral treatments then introducing oral treatments followed by intravesical instillations. If these treatments fail then more invasive treatments such as botulinum toxin injections, neuromodulation, or surgery could be suggested. CONCLUSION Unfortunately for all treatments, the numbers are limited and, therefore, the evidence base is not strong. Further suggestions for research are suggested.
