Abstract
BACKGROUND Major depressive disorder (MDD) and interstitial cystitis (IC) are two highly debilitating conditions that often coexist with reciprocal effect, significantly exacerbating patients' suffering. However, the molecular underpinnings linking these disorders remain poorly understood. METHODS Transcriptomic data from GEO datasets including those of MDD and IC patients was systematically analyzed to develop and validate our model. Following removal of batch effect, differentially expressed genes (DEGs) between respective disease and control groups were identified. Shared DEGs of the conditions then underwent functional enrichment analyses. Additionally, immune infiltration analysis was quantified through ssGSEA. A diagnostic model for MDD was constructed by exploring 113 combinations of 12 machine learning algorithms with 10-fold cross-validation on the training sets following by external validation on test sets. Finally, the "Enrichr" platform was utilized to identify potential drugs for MDD. RESULTS Totally, 21 key genes closely associated with both MDD and IC were identified, predominantly involved in immune processes based on enrichment analyses. Immune infiltration analysis revealed distinct profiles of immune cell infiltration in MDD and IC compared to healthy controls. From these genes, a robust 11-gene (ABCD2, ATP8B4, TNNT1, AKR1C3, SLC26A8, S100A12, PTX3, FAM3B, ITGA2B, OLFM4, BCL7A) diagnostic signature was constructed, which exhibited superior performance over existing MDD diagnostic models both in training and testing cohorts. Additionally, epigallocatechin gallate and 10 other drugs emerged as potential targets for MDD. CONCLUSION Our work developed a diagnostic model for MDD employing a combination of bioinformatic techniques and machine learning methods, focusing on shared genes between MDD and IC.

Abstract
Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a debilitating urologic pain condition with few treatment advances in the past 25 years. Individuals with IC/BPS often experience significant psychological distress, which worsens symptoms and functioning. To date, there have been no large-scale, randomized controlled trials (RCTs) of comprehensive psychological interventions for IC/BPS. We conducted a 2:1 RCT of an 8-session patient-informed cognitive-behavioral therapy (CBT) intervention designed for IC/BPS for reducing pain-related symptoms and improving quality of life, delivered through telemedicine. Individuals with IC/BPS (N = 78) were randomized to receive either 8 weeks of CBT specifically designed for IC/BPS (n = 52) or an attention control condition (n = 26). Urologic symptoms (Genitourinary Pain Index, GUPI), pain-related symptoms, affective distress, and quality of life were evaluated before, immediately after, and 3 months posttreatment. Both conditions reported significant but similar reductions (P = 0.922) in the a priori primary outcome of genitourinary symptoms at posttreatment (GUPI reduction = 6.6 vs 4.8, for CBT and control, respectively) and long-term follow-up (8.1 vs 6.6, for CBT and control). However, the CBT group had significantly greater improvement in Patient Global Impression of Change (PGIC) scores and was significantly more likely to be treatment responders (PGIC ≥ 6) (37% vs 8%, P = 0.019 for CBT and control), with a large relative effect size (OR = 6.68). A subgroup analysis of CBT recipients showed that responders (PGIC
6) displayed significant reductions in genitourinary symptoms (P = 0.023), pain intensity (P = 0.027), and pain interference (P = 0.013) posttreatment. Telemedicine-delivered pain CBT for IC/BPS shows promise for improving outcomes, and this trial demonstrates the need for larger RCTs of CBT for IC/BPS.

Abstract
BACKGROUND Interstitial cystitis/bladder pain syndrome (IC/BPS) is an at least 6-mo noninfectious bladder inflammation of unknown origin characterized by chronic suprapubic, abdominal, and/or pelvic pain. Although the term cystitis suggests an inflammatory or infectious origin, no definite cause has been identified. It occurs in both sexes, but women are twice as much affected. AIM To systematically review evidence of psychiatric/psychological changes in persons with IC/BPS. METHODS Hypothesizing that particular psychological characteristics could underpin IC/BPS, we investigated in three databases the presence of psychiatric symptoms and/or disorders and/or psychological characteristics in patients with IC/BPS using the following strategy: ("interstitial cystitis" OR "bladder pain syndrome") AND ("mood disorder" OR depressive OR antidepressant OR depression OR depressed OR hyperthymic OR mania OR manic OR rapid cyclasterisk OR dysthymiasterisk OR dysphoriasterisk). RESULTS On September 27, 2023, the PubMed search produced 223 articles, CINAHL 62, and the combined PsycLIT/ PsycARTICLES/PsycINFO/Psychology and Behavioral Sciences Collection search 36. Search on ClinicalTrials.gov produced 14 studies, of which none had available data. Eligible were peer-reviewed articles reporting psychiatric/psychological symptoms in patients with IC/BPS, i.e. 63 articles spanning from 2000 to October 2023. These studies identified depression and anxiety problems in the IC/BPS population, along with sleep problems and the tendency to catastrophizing. CONCLUSION Psychotherapies targeting catastrophizing and life stress emotional awareness and expression reduced perceived pain in women with IC/BPS. Such concepts should be considered when implementing treatments aimed at reducing IC/BPS-related pain.

Abstract
BACKGROUND Interstitial cystitis/painful bladder syndrome (IC) is a chronic pelvic pain condition which has high comorbidity with other nociplastic, or unexplained, pain disorders [e.g. fibromyalgia (FM), irritable bowel syndrome (IBS), and myalgic encephalomyelitis/chronic fatigue (ME/CFS)] and some psychiatric conditions [major depressive disorder (MDD) and panic disorder (PD)]. Here we investigated the shared familiality of IC and these other nociplastic and psychiatric conditions. METHODS Subjects were identified in the Utah Population Database, which links genealogy data back to the 1800s to medical record diagnosis billing code data back to 1995. We computed the relative risk of each of these disorders among first (FDR), second (SDR), and third-degree relatives (TDR) of six proband groups: IC, FM, IBS, ME/CFS, PD, and MDD. Given the known familial aggregation of each of these disorders, we conducted our analyses to test for heritable interrelationships using proband subgroups whose members did not have the diagnosis assessed in their relatives. RESULTS We observed strong evidence for heritable interrelationships among all six disorders. Most analyses indicated significantly increased risk for each of the six disorders in FDR, SDR, and TDR of all or most proband groups. Out of 30 possible bidirectional disorder interrelationships, 26 were significant among FDR, 23 were significant among SDR, and 7 were significant among TDR. Clustering was observed in both close and distant relatives. CONCLUSIONS Our results support a common, heritable component to IC and other nociplastic and psychiatric conditions.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic pain disorder causing symptoms of urinary frequency, urgency, and bladder discomfort or pain. Although this condition affects a large population, little is known about its etiology. Genetic analyses of whole exome sequencing are performed on 109 individuals with IC/BPS. One family has a previously reported SIX5 variant (ENST00000317578.6:c.472G>A, p.Ala158Thr), consistent with Branchiootorenal syndrome 2 (BOR2). A likely pathogenic heterozygous variant in ATP2A2 (ENST00000539276.2:c.235G>A, p.Glu79Lys) is identified in two unrelated probands, indicating possible Darier-White disease. Two private heterozygous variants are identified in ATP2C1 (ENST00000393221.4:c.2358A>T, p.Glu786Asp (VUS/Likely Pathogenic) and ENST00000393221.4:c.989C>G, p.Thr330Ser (likely pathogenic)), indicative of Hailey-Hailey Disease. Sequence kernel association test analysis finds an increased burden of rare ATP2C1 variants in the IC/BPS cases versus a control cohort (p = 0.03, OR = 6.76), though does not survive Bonferroni correction. The data suggest that some individuals with IC/BPS may have unrecognized Mendelian syndromes. Comprehensive phenotyping and genotyping aid in understanding the range of diagnoses in the population-based IC/BPS cohort. Conversely, ATP2C1, ATP2A2, and SIX5 may be candidate genes for IC/BPS. Further evaluation with larger numbers is needed. Genetically screening individuals with IC/BPS may help diagnose and treat this painful disorder due to its heterogeneous nature.

Abstract
INTRODUCTION Women with genitourinary pain, a hallmark symptom of interstitial cystitis/bladder pain syndrome (IC/BPS), are at a two- to four-fold risk for depression as compared to women without genitourinary pain. Despite the pervasive impact of IC/BPS on psychological health, there is a paucity of empirical research on understanding the relation between IC/BPS and psychological distress. It has been previously reported that women with overactive bladder use increased compensatory coping and these behaviors are associated with heightened anxiety and stress. However, it is unknown whether a similar pattern emerges in IC/BPS populations, as ICBPS and OAB share many similar urinary symptoms. The current study examined the relationship between compensatory coping behaviors and symptoms of psychological distress in a sample of women with IC/BPS to inform understanding of risk and potential mechanisms for intervention. METHOD This was a secondary analysis of an observational cohort of women with bladder symptoms. Fifty-five adult women with IC/BPS completed validated assessments of genitourinary symptoms, emotional distress, and bladder coping behaviors. Five compensatory coping behaviors were summed to create a total Bladder Coping Score. Linear regression examined associations between individual coping behaviors, total compensatory coping scores, and other risk variables. RESULTS Most (93%) participants reported use of at least one compensatory coping behavior. Age, education level, history of vaginal birth, and symptom severity were all associated with greater compensatory coping scores, and anxiety was not. Beyond the influence of symptom severity, higher levels of depression were significantly associated with higher compensatory coping scores. DISCUSSION Greater compensatory coping was associated with increased depression but not anxiety, suggesting different profiles of coping and psychological distress may exist among different types of bladder dysfunction.

[PMID: 36242631 PMCID: PMC9569001 DOI: 10.1007/s00192-022-05383-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 09/22/2022] [Indexed: 11/30/2022]
Abstract
Introduction and hypothesis A prospective clinical, preliminary study was performed in patients with interstitial cystitis/bladder pain syndrome (IC/BPS) who were nonresponders to conventional treatment and received intravesical ozone as a therapeutic alternative. Methods Sixteen patients received six applications of intravesical ozone at a concentration of 41 μg/mL. We evaluated therapeutic efficacy by the percentage reduction of Interstitial Cystitis Symptom and Problem Index scores (ICSI/ICPI—the O'Leary–Sant symptom index), recurrence rate, nonresponse, and side effects in scores collected on admission (pre-treatment), at the end of the therapeutic protocol (post-treatment), and 180 days (follow-up) after the last ozone application. Results The mean age of women was 52.9 years (SD: 15.5), and the duration of symptoms was 5.7 years (SD: 7.1). The median ICSI on admission was 17 (IQR: 14.25–19.5) and at follow-up was 0.5 (IQR: 0–2), with a reduction of 97.5% (CI: 85.7–100). The median ICSI/ICPI on admission was 31.5 (IQR: 29–35.2) and at follow-up was 2.0 (IQR: 0–3.75), with a reduction of 92.3% (CI: 88.8–100). The recurrence rate was only 6.25%, and no patients were nonresponders to the treatment. Conclusions The application of intravesical ozone was effective in the treatment of patients with IC/BPS who were nonresponders to conventional therapy, showing a progressive and safe effect, at least in the short term.

Abstract
INTRODUCTION AND HYPOTHESIS The aim of this systematic review and meta-analysis is, looking at different care settings, to examine prevalence rates of psychological distress-level comorbidities in female interstitial cystitis/bladder pain syndrome (IC/BPS) patients, their impact on Quality of Life (QoL), and the correlation between such comorbidities and symptom severity. METHODS A systematic literature search according to PRISMA guidelines was conducted in PubMed, PsycInfo, Web of Science, Science Direct, and Google Scholar. RESULTS Twenty-nine studies were found that met inclusion criteria. Prevalence rates of depression and anxiety are higher in IC/BPS patients compared to the general population; however, due to a wide array of measurements, statistical comparisons between care settings were only possible in two cases showing mixed results. No studies meeting inclusion criteria exist that examine PTSD and borderline personality disorder, though rates of past traumatic experiences seem to be higher in patients than in healthy controls. Psychological comorbidities of the distress category, especially depression, are found in most studies to be related to symptom severity, also yielding statistically significant associations. CONCLUSIONS While there is still need for studies focused on some of the comorbidities as well as on different care settings, the data already show that psychological comorbidities of the distress category play an important role in IC/BPS patients regarding suffering, QoL, and symptom severity, thus emphasizing the need for highly specialized interdisciplinary treatment.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is not only a chronic urinary bladder pain syndrome but is also associated with multifactorial etiology. Our study aimed to test the hypothesis that IC/BPS is associated with subsequent increased risks of outpatient visits and hospitalizations. Using nationwide database, the diagnoses were based on the International Classification Codes (ICD-9-CM) (595.1) of at least three outpatient services during 2002-2008, (n = 27,990) and cystoscopic finding Hunner type and/or glomerulation with pre-audit criteria. All recruited cases monitored for subsequent outpatient visits and hospitalizations for 2 years, including all-cause and specialty-specific departments, were classified according to medical specialty and age group (<40, 40-60, ≥60 years of age). IC/BPS patients have more overall outpatient department (OPD) visits and an overall adjusted incidence rate ratio (IRR) of 1.64. As for specialty, IRRs were higher in psychiatry (2.75), Chinese medicine (2.01), and emergency medicine (2.00), besides urology and gynecology. The IRRs decreased as age advanced (2.01, 1.71, and 1.44, respectively), except for gynecology (2.42, 2.52, and 2.81). A similar phenomenon happens in hospitalization with IRR of 1.69. Due to claim data characteristics, whether ulcer type IC/BPS findings can be deductive to non-ulcer type remains inclusive. Current results indicate the impacts of healthcare burden in broad spectrum about IC/PBS patients. IC/BPS has been suggested to be associated with lower threshold of healthcare visits and some coexisting disease and is comprised of systemic dysregulation, and is beyond the scope of local bladder-urethra disease. Adequate recognition of associated or comorbid factors and possible recommendation or referral for IC/BPS patients can help provide better healthcare quality.

Abstract
OBJECTIVE To evaluate the quality of life of patients with interstitial cystitis/bladder pain syndrome (IC/BPS), to compare the difference between IC/BPS and overactive bladder (OAB) pain syndrome, and to explore the related factors affecting the quality of life of IC/BPS patients. METHODS The demographic data of female outpatients with IC/BPS in Beijing Hospital and other medical centers in China were collected. The quality of life of the patients was investigated by multi-angle questionnaires and compared with the data of OAB patients. According to the influence degree of quality of life, the patients with IC/BPS were divided into mild-moderate group and severe group. RESULTS In this study, 109 patients with IC/BPS were included. The average age was (46.4±14.3) years and the average course of disease was (39.4±51.6) months. Compared with the OAB patients, the patients in IC/BPS group had a longer average course of disease (P=0.008), a lower proportion of the patients of first visit for the disease (P < 0.001), a higher score of the American Urological Association symptom index (AUA-SI) (P < 0.001), a lower body mass index (BMI) ratio (P=0.016), and a lower incidence of constipation (P=0.006). IC/BPS had the greatest impact on family life, followed by social activity. The score of IC/BPS related symptoms on family life was significantly higher than that of the OAB group (P=0.003). The top three symptoms of the IC/BPS patients were pain (45%), frequency (28%) and urgency (17%). The score of quality of life in the IC/BPS patients was significantly higher than that in the OAB patients (P < 0.001). Caffeine intake (P=0.034) and constipation (P=0.003) might be the factors influencing the quality of life of the patients with IC/BPS. CONCLUSION IC/BPS has a great influence on the quality of life of patients. Caffeine intake and constipation may be related factors affecting the quality of life of patients with IC/BPS. Urologists should recommend changes in diet and lifestyle to reduce symptoms and improve the patients' quality of life.

Abstract
AIMS Two phase 2 studies were conducted to assess the efficacy and safety of lidocaine-releasing intravesical system (LiRIS) in patients with interstitial cystitis/bladder pain syndrome (IC/BPS) with (Study 001; NCT02395042) or without, (Study 002; NCT02411110) Hunner lesions (HL). METHODS Both were multicenter, randomized, double-blind, placebo-controlled, and enrolled women aged ≥18 years. In Study 001, patients were randomized 2:1:1 to LiRIS 400 mg/LiRIS 400 mg, placebo/LiRIS 400 mg, or placebo/placebo for a continuous 28 (2 × 14)-day period. In Study 002, patients were randomized 1:1 to LiRIS 400 mg or placebo for a continuous (single treatment) 14-day period. RESULTS In total, 59 and 131 patients received treatment in Studies 001 and 002, respectively. There was no statistically significant difference in the primary endpoint, the change from baseline to Week 4 of follow-up post-removal in mean daily average bladder numeric rating scale (NRS) pain score in either study (Study 001: placebo/placebo, -1.6; LiRIS/LiRIS, -2.7, p = 0.142; placebo/LiRIS, -2.5, p = 0.319; Study 002: LiRIS -1.2; placebo, -1.5, p = 0.505). There was no statistically significant difference between groups in daily worst NRS pain score, number of micturitions/day or urgency episodes/day. There was no clear trend for reduction in number of HL for LiRIS vs placebo. The frequency of treatment-emergent adverse events was similar between treatment groups in both studies; most were mild or moderate intensity. CONCLUSION These studies did not demonstrate a treatment effect of LiRIS 400 mg compared with placebo, either in patients with IC/BPS with HL, or in those without HL.

Abstract
The aim of this study was to explore the lived experience of interstitial cystitis (IC)/painful bladder syndrome (PBS). A phenomenological approach with emphasis on reflection and openness was adopted. Twenty women diagnosed with IC an average of nine years prior to data collection produced a written account of their experiences. The textual data was analyzed using thematic analysis. Four themes were derived from data analysis: diagnostic uncertainty; restrictions and limitations on life; self-management; and interpersonal relationships and social support. Women reported issues in receiving a diagnosis of IC, undergoing numerous diagnostic tests, and experiencing multiple referrals. Having undergone numerous treatments with limited success, women sought information and management strategies outside of standard medical care and reported a negative impact on sexual and social relationships. The findings illustrate the complex nature of women’s experiences and the physical and psychological impacts and effects of IC/PBS on women’s daily lives.

Abstract
BACKGROUND Interstitial cystitis/bladder pain syndrome (IC/BPS) is a debilitating condition carrying substantial psychosocial burden. Psychological treatment for IC/BPS is little studied, and there are barriers to its use in clinical management. Whether psychological treatments benefit patients with IC/BPS is unclear and we do not know if such treatments would meet patient needs. AIMS Incorporating patient-reported needs and acknowledging diversity in pain experiences can inform patient-centered interventions for IC/BPS. This project characterized the experience of living with IC/BPS and patient perceptions of needs in its treatment, with the goal of informing patient-centered treatment for IC/BPS. METHODS Using both quantitative and qualitative methods, 27 females with IC/BPS participated in a focus group and completed validated self-report assessments evaluating urinary symptoms, pain, and emotional functioning. Focus groups were audio recorded and transcribed, then coded and analyzed using an iterative inductive/deductive approach. Linear regression models evaluated the relationship between psychological functioning and symptom severity. RESULTS We conducted six focus groups between 8/2017-12/2017. Five major themes emerged from qualitative analysis: managing physical symptoms, emotional symptoms, impact on daily life and socio-contextual factors, responding to illness, and addressing needs in treatment. The physiological and emotional consequences of IC/BPS were reported, highlighting their impact on interpersonal relationships and challenges obtaining appropriate treatment for IC/BPS. Quantitative analysis showed depression levels were significantly associated with worsened IC/BPS symptomology, after controlling for known confounding factors. CONCLUSION Individuals with IC/BPS could benefit from tailored psychological interventions focusing on pain management, emotion regulation, communications skills, along with sexual dysfunction and intimacy fears.

Abstract
Traditional Chinese medicine (TCM) is commonly used for urinary symptoms in Eastern countries. Since there are few effective treatments available for patients with interstitial cystitis/bladder pain syndrome (IC/BPS), the psychological burden leads to increased healthcare-seeking behavior. Some patients may therefore seek TCM treatment for related urinary symptoms. Due to limited clinical research evaluating the effects of TCM on IC/BPS, we conducted a nationwide population-based cohort study to investigate the relationship between TCM and mental disorders among these patients. The IC/BPS cohort and its matched non-IC/BPS comparison cohort were recruited from the National Health Insurance (NHI) Research Database between 2000 and 2011. Patients with the use of Chinese herbal medicine (CHM) granules or acupuncture over 90 days per year were enrolled as the TCM users. Multivariable Cox proportional hazards models were used to evaluate the hazard ratio (HR) of mental disorders related to interstitial cystitis. The incidence of mental disorders in the 2 cohorts was assessed with Kaplan-Meier curves. A total of 1123 patients with IC/BPS and 4492 matched non-IC/BPS subjects were included in this study. The IC/BPS cohort demonstrated higher incidence rate of mental disorders than the cohort without IC/BPS (adjusted HR: 2.21, 95% confidence interval [CI]: 1.73-2.81). There was no statistically significant difference in the risk of mental disorders between IC/BPS patients with and without CHM granules or acupuncture treatment (adjusted HR: 0.99, 95% CI: 0.58-1.68). Our results indicated that CHM and acupuncture showed insignificant efficacy in the prevention of mental disorders in IC/BPS patients.

Abstract
Background Bladder-related pain symptoms in patients with bladder pain syndrome/interstitial cystitis (BPS/IC) are often accompanied by depression and memory deficits. Magnesium deficiency contributes to neuroinflammation and is associated with pain, depression, and memory deficits. Neuroinflammation is involved in the mechanical allodynia of cyclophosphamide (CYP)-induced cystitis. Magnesium-L-Threonate (L-TAMS) supplementation can attenuate neuroinflammation. This study aimed to determine whether and how L-TAMS influences mechanical allodynia and accompanying depressive symptoms and memory deficits in CYP-induced cystitis. Methods Injection of CYP (50 mg/kg, intraperitoneally, every 3 days for 3 doses) was used to establish a rat model of BPS/IC. L-TAMS was administered in drinking water (604 mg·kg−1·day−1). Mechanical allodynia in the lower abdomen was assessed with von Frey filaments using the up-down method. Forced swim test (FST) and sucrose preference test (SPT) were used to measure depressive-like behaviors. Novel object recognition test (NORT) was used to detect short-term memory function. Concentrations of Mg2+ in serum and cerebrospinal fluid (CSF) were measured by calmagite chronometry. Western blot and immunofluorescence staining measured the expression of tumor necrosis factor-α/nuclear factor-κB (TNF-α/NF-κB), interleukin-1β (IL-1β), and N-methyl-d-aspartate receptor type 2B subunit (NR2B) of the N-methyl-d-aspartate receptor in the L6–S1 spinal dorsal horn (SDH) and hippocampus. Results Free Mg2+ was reduced in the serum and CSF of the CYP-induced cystitis rats on days 8, 12, and 20 after the first CYP injection. Magnesium deficiency in the serum and CSF correlated with the mechanical withdrawal threshold, depressive-like behaviors, and short-term memory deficits (STMD). Oral application of L-TAMS prevented magnesium deficiency and attenuated mechanical allodynia (n = 14) and normalized depressive-like behaviors (n = 10) and STMD (n = 10). The upregulation of TNF-α/NF-κB signaling and IL-1β in the L6–S1 SDH or hippocampus was reversed by L-TAMS. The change in NR2B expression in the SDH and hippocampus in the cystitis model was normalized by L-TAMS. Conclusions Normalization of magnesium deficiency by L-TAMS attenuated mechanical allodynia, depressive-like behaviors, and STMD in the CYP-induced cystitis model via inhibition of TNF-α/NF-κВ signaling and normalization of NR2B expression. Our study provides evidence that L-TAMS may have therapeutic value for treating pain and comorbid depression or memory deficits in BPS/IC patients.

Abstract
Chronic bladder pain evokes asymmetric behavior in neurons across the left and right hemispheres of the amygdala. An agent-based computational model was created to simulate the firing of neurons over time and in response to painful bladder stimulation. Each agent represents one neuron and is characterized by its location in the amygdala and response type (excited or inhibited). At each time step, the firing rates (Hz) of all neurons are stochastically updated from probability distributions estimated from data collected in laboratory experiments. A damage accumulation model tracks the damage accrued by neurons during long-term, painful bladder stimulation. Emergent model output uses neural activity to measure temporal changes in pain attributed to bladder stimulation. Simulations demonstrate the model's ability to capture acute and chronic pain and its potential to predict changes in pain similar to those observed in the lab. Asymmetric neural activity during the progression of chronic pain is examined using model output and a sensitivity analysis.

Abstract
Interstitial cystitis/bladder pain syndrome is a chronic bladder condition associated with pain and voiding dysfunction that is often regarded as a neurogenic cystitis. Patient symptoms are correlated with the presence of urothelial lesions. We previously characterized a murine neurogenic cystitis model that recapitulates mast cell accumulation and urothelial lesions, and these events were dependent on TNF. To further explore the role of TNF in bladder inflammation and function, we generated a transgenic mouse model with chronic TNF overexpression in urothelium under the control of the uroplakin II (UPII) promoter. Transgenic mouse lines were maintained by backcross onto wild-type C57BL/6J mice and evaluated for pelvic tactile allodynia as a measure of visceral pain, urinary function, and urothelial lesions. TNF mRNA and protein were expressed at greater levels in bladders of UPII-TNF mice than in those of wild-type mice. UPII-TNF mice showed significantly increased urinary frequency and decreased void volume. UPII-TNF mice had increased urothelial apoptosis and loss of urothelial integrity consistent with urothelial lesions. Overexpression of TNF was also associated with pelvic tactile allodynia. Consistent with these findings, UPII-TNF mice exhibited increased bladder afferent activity in response to stretch ex vivo. In summary, UPII-TNF mice display significant pelvic pain, voiding dysfunction, urothelial lesions, and sensory input. Thus UPII-TNF mice are a model for characterizing mechanisms of interstitial cystitis symptoms and evaluating therapies.

Abstract
AIMS Psychosocial factors amplify symptoms of Interstitial Cystitis (IC/BPS). While psychosocial self-management is efficacious in other pain conditions, its impact on an IC/BPS population has rarely been studied. The objective of this review is to learn the prevalence and impact of psychosocial factors on IC/BPS, assess baseline psychosocial characteristics, and offer recommendations for assessment and treatment. METHOD Following PRISMA guidelines, primary information sources were PubMed including MEDLINE, Embase, CINAHL, and GoogleScholar. Inclusion criteria included: (i) a clearly defined cohort with IC/BPS or with Chronic Pelvic Pain Syndrome provided the IC/BPS cohort was delineated with quantitative results from the main cohort; (ii) all genders and regions; (iii) studies written in English from 1995 to April 14, 2017; (iv) quantitative report of psychosocial factors as outcome measures or at minimum as baseline characteristics. RESULTS Thirty-four of an initial 642 articles were reviewed. Quantitative analyses demonstrate the magnitude of psychosocial difficulties in IC/BPS, which are worse than average on all measures, and fall into areas of clinical concern for 7 out of 10 measures. Meta-analyses shows mean Mental Component Score of the Short-Form 12 Health Survey (MCS) of 40.80 (SD 6.25, N = 2912), where <36 is consistent with severe psychological impairment. Averaged across studies, the population scored in the range seen in clinical depression (CES-D 19.89, SD 13.12, N = 564) and generalized anxiety disorder (HADS-A 8.15, SD 4.85, N = 465). CONCLUSION The psychological impact of IC/BPS is pervasive and severe. Existing evidence of treatment is lacking and suggests self-management intervention may be helpful.

Abstract
Interstitial cystitis/bladder pain syndrome (IC) is associated with significant morbidity, yet underlying mechanisms and diagnostic biomarkers remain unknown. Pelvic organs exhibit neural crosstalk by convergence of visceral sensory pathways, and rodent studies demonstrate distinct bacterial pain phenotypes, suggesting that the microbiome modulates pelvic pain in IC. Stool samples were obtained from female IC patients and healthy controls, and symptom severity was determined by questionnaire. Operational taxonomic units (OTUs) were identified by16S rDNA sequence analysis. Machine learning by Extended Random Forest (ERF) identified OTUs associated with symptom scores. Quantitative PCR of stool DNA with species-specific primer pairs demonstrated significantly reduced levels of E. sinensis, C. aerofaciens, F. prausnitzii, O. splanchnicus, and L. longoviformis in microbiota of IC patients. These species, deficient in IC pelvic pain (DIPP), were further evaluated by Receiver-operator characteristic (ROC) analyses, and DIPP species emerged as potential IC biomarkers. Stool metabolomic studies identified glyceraldehyde as significantly elevated in IC. Metabolomic pathway analysis identified lipid pathways, consistent with predicted metagenome functionality. Together, these findings suggest that DIPP species and metabolites may serve as candidates for novel IC biomarkers in stool. Functional changes in the IC microbiome may also serve as therapeutic targets for treating chronic pelvic pain.

Abstract
Current management of bladder pain syndrome (BPS) was evaluated through a prospective electronic questionnaire posted on three patient support groups and sent to all members on the British Society of Urogynaecology (BSUG) database. Methods of diagnosis and treatment were assessed. 133 patients and 69 clinicians participated in the survey. Patients reported their main symptom to be pain when their bladder was full in 80% (n = 107) and the most bothersome symptom was pelvic pain (22%, n = 29). 93% (n = 64) of clinicians made their diagnosis by history and cystoscopy. 78% (n = 54) of clinicians treated patients with amitriptyline and 75% (n = 52) by dietary modification while 77% (n = 102) of patients reported using simple analgesia, 74% (n = 98) dietary modification and 62% (n = 83) low-dose long-term antibiotics. There is wide variation in diagnostic methods and treatments of BPS used by clinicians and experienced by patients with no obvious consensus. National guidance is needed to help standardise care.

Abstract
PURPOSE To explore the association between bladder pain syndrome/interstitial cystitis (BPS/IC) and the risk of subsequent healthcare-seeking behavior for common mental disorders in Taiwan using a population-based administrative database. MATERIALS AND METHODS Both BPS/IC subjects and their age- and sex-matched non-BPS/IC control subjects who had no previous insomnia and mental diseases, including anxiety, depression, were subsequent serviced for these mental disorders by psychiatrists from the recruited date between 2002 and 2010. The risk of outcomes was assessed with Kaplan-Meier curves; and the impact of BPS/IC was estimated with Poisson regression analysis and Cox proportional hazards models. RESULTS We included 16,185 BPS/IC subjects and 32,370 non-BPS/IC subjects, with a mean age of 46 years and 73.5 % of women. Difference of the prevalence of hypertension, diabetes, chronic kidney disease, and hyperlipidemia between groups was not significant difference. Subjects with BPS/IC had a significant higher incidence rate of anxiety, depression, and insomnia than the matched controls (92.9 vs 38.4, 101.0 vs 42.2, 47.5 vs 23.0; per 10,000 person-year). After adjusting for age, sex, and common comorbidities in multivariable analysis, BPS/IC remained a significant predictor with hazard ratio and 95 % confidence incidence, 2.4 (2.2-2.7), 2.4 (2.2-2.6), and 2.1 (1.8-2.4) for anxiety, depression, and insomnia, respectively. CONCLUSION Patients with BPS/IC are at risk of development of anxiety, depression, and insomnia. These findings can help guide urologists, urogynecologists, and psychiatrists toward early identification and treatment of psychological complications that may develop in BPS/IC patients.

Abstract
OBJECTIVES This study aimed to describe the psychological functioning of interstitial cystitis/bladder pain syndrome patients utilizing MMPI-2-RF scoring. METHODS The MMPI-2 was administered to 60 individuals who reported a diagnosis of IC. Responses were scored in the MMPI-2-RF format. Fifty-one protocols were deemed valid. RESULTS Elevations were discovered on scales FBS-r (symptom validity), RC1 (somatic complaints), and MLS (malaise). Participants were split into two groups based on extreme elevations on RC1; the high RC1 group produced higher scores on 39 scales including clinically significant elevations on 17 scales. CONCLUSION Over 25% of this sample had an emotional component to their physical concerns. This knowledge about the psychological characteristics of IC patients may have clinical utility for physicians and other treatment providers. The results argue strongly for psychological evaluation as a component of IC diagnosis and treatment. Those with significant emotional overlay to their somatic complaints may be best managed through psychological interventions and minimally invasive treatments.

Abstract
AIM Vascular factors are proposed in the etiology of bladder pain syndrome/interstitial cystitis (BPS/IC). In this study, we investigated the risk of stroke among women following a diagnosis of BPS/IC over 3 years of follow-up, compared to controls without a BPS/IC diagnosis. METHODS This retrospective cohort study used data retrieved from the Taiwan "Longitudinal Health Insurance Database 2000." We identified 847 women who received a diagnosis of BPS/IC between January 1, 2001 and December 31, 2008 (study group) and 4,235 comparison women (women without a BPS/IC diagnosis matched on age and other selected demographic variables. All subjects were tracked for 3 years following the index date to identify those who received a diagnosis of stroke during follow-up. RESULTS The stroke incidence rate was 20.86 (95% confidence interval (CI): 15.78-27.07) and 11.65 (95% CI: 9.88-13.64) per 1,000 person-years among the study and comparison cohorts, respectively. Cox regression analysis showed a stroke hazard ratio (HR) of 1.52 (95% CI: 1.09-2.14) in the BPS/IC group relative to the comparison group over 3-year follow-up, after adjusting for hypertension, diabetes, coronary heart disease, atrial fibrillation, hyperlipidemia, and chronic kidney disease. The adjusted HR of ischemic stroke was 1.52 (95% CI: 1.02-2.27). However, there was no significant difference between the two groups in hemorrhagic stroke risk. CONCLUSIONS Our study demonstrates an association between BPS/IC and a subsequent ischemic stroke diagnosis among women in Taiwan.

Abstract
BACKGROUND Chronic pain is common in patients with inflammatory bowel disease and often attributed to inflammation. However, many patients with inflammatory bowel disease without evidence of active disease continue to experience pain. This study was undertaken to determine the prevalence of pain in patients with ulcerative colitis (UC) and examine the role of inflammation and psychiatric comorbidities in patients with UC with pain. METHODS We performed a retrospective cross-sectional analysis of adult patients with UC seen at a tertiary referral inflammatory bowel disease center. Age, gender, disease duration and extent, abdominal pain rating, quality of life, physician global assessment, endoscopic and histological rating of disease severity, C reactive protein, and erythrocyte sedimentation rate were abstracted. RESULTS A total of 1268 patients were identified using billing codes for colitis. Five hundred and two patients (48.2% women) met all inclusion criteria. Two hundred and sixty-two individuals (52.2%) complained of abdominal pain, with 108 individuals (21.5%) describing more frequent pain ("some of the time or more"). Of those with quiescent disease (n = 326), 33 patients (10%) complained of more frequent pain. Physician global assessment, endoscopic and histological severity rating, erythrocyte sedimentation rate, and C reactive protein significantly correlated with pain ratings. The best predictors of pain were physician global assessment, C reactive protein and erythrocyte sedimentation rate, female gender, and coexisting mood disorders. CONCLUSIONS Abdominal pain affects more than 50% of patients with UC. Although inflammation is important, the skewed gender distribution and correlation with mood disorders highlight parallels with functional bowel disorders and suggest a significant role for central mechanisms. Management strategies should thus go beyond a focus on inflammation and also include interventions that target psychological mechanisms of pain.

Abstract
BACKGROUND Although the etiology of bladder pain syndrome/interstitial cystitis (BPS/IC) is still unclear, a common theme with BPS/IC patients is comorbid disorders which are related to the autonomic nervous system that connects the nervous system to end-organs. Nevertheless, no study to date has reported the association between hyperthyroidism and BPS/IC. In this study, we examined the association of IC/BPS with having previously been diagnosed with hyperthyroidism in Taiwan. DESIGN Data in this study were retrieved from the Longitudinal Health Insurance Database. Our study consisted of 736 female cases with BPS/IC and 2208 randomly selected female controls. We performed a conditional logistic regression to calculate the odds ratio (OR) for having previously been diagnosed with hyperthyroidism between cases and controls. RESULTS Of the 2944 sampled subjects, there was a significant difference in the prevalence of prior hyperthyroidism between cases and controls (3.3% vs. 1.5%, p<0.001). The conditional logistic regression analysis revealed that compared to controls, the OR for prior hyperthyroidism among cases was 2.16 (95% confidence interval (CI): 1.27∼3.66). Furthermore, the OR for prior hyperthyroidism among cases was 2.01 (95% CI: 1.15∼3.53) compared to controls after adjusting for diabetes, coronary heart disease, obesity, hyperlipidemia, chronic pelvic pain, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, depression, panic disorder, migraines, sicca syndrome, allergies, endometriosis, and asthma. CONCLUSIONS Our study results indicated an association between hyperthyroidism and BPS/IC. We suggest that clinicians treating female subjects with hyperthyroidism be alert to urinary complaints in this population.

Abstract
OBJECTIVES The aim of this study was to verify the efficacy and safety of intravesical treatment combining sodium hyaluronate (HA) and chondroitin sulfate (CS) in patients with interstitial cystitis/bladder pain syndrome (IC/BPS). METHODS Between February 2010 and May 2011, 20 consecutive women with IC/BPS were treated with intravesical instillations containing sodium HA (1.6%; 800 mg/50 ml) and sodium CS (2%; 1 g/50 ml) weekly for the first month, biweekly for the second month, and then monthly for at least 3 months. Before and after treatment, all patients filled in the Interstitial Cystitis Symptom Index and Problem Index (ICSI/ICPI), the Patient Health Questionnaire 9 and the Pelvic Pain and Urgency/Frequency Patient Symptom Scale (PUF). Treatment efficacy was assessed by comparing the pre- and post-treatment mean scores of the three questionnaires using Student's t test (p value <0.05 was considered significant). RESULTS Statistically significant mean decreases in ICSI (from 13.0 to 9.3; p = 0.0003), ICPI (from 11.35 to 8.85; p = 0.0078) and PUF (from 20.0 to 15.75; p = 0.0007) questionnaire scores were seen. No cases of side effects or complications were observed. The mean follow up was 5 months. CONCLUSIONS Despite the limitations of this study, the outcomes confirmed the role of combination therapy with HA and CS as a safe and effective option for the treatment of IC/BPS. Further randomized controlled studies with a higher number of patients and a longer follow-up period are needed to confirm these results.

Abstract
AIM Vascular factor was proposed as being involved in the etiology of bladder pain syndrome/interstitial cystitis (BPS/IC). However, few studies have attempted to investigate the relationship between BPS/IC and cardiovascular disease. This study aimed to investigate the risk of coronary heart disease (CHD) among BPS/IC subjects during a 3-year follow-up period. METHODS Data for this retrospective matched-cohort study were retrieved from the Taiwan "Longitudinal Health Insurance Database 2000." There were 752 BPS/IC female subjects in the study cohort and 3,760 randomly selected female subjects in the comparison cohort. We individually tracked each subject for 3 years and identified each subject that received a subsequent diagnosis of CHD during that follow-up period. RESULTS Results showed that incidence rates of CHD during the 3-year follow-up period were 19.50 (95% confidence interval (CI): 14.35-25.95) and 8.87 (95% CI: 7.25-10.74) per 1,000 person-years for the study and comparison cohorts, respectively. The Cox proportional hazards regression suggested that the hazard ratio for CHD in subjects with BPS/IC was 1.65 (95% CI: 1.09-2.48) within the 3-year follow-up period following the index date compared to the comparison subjects after adjusting for monthly income, geographic region, hypertension, diabetes, hyperlipidemia, chronic kidney disease, bladder outlet obstruction, urinary tract infection, chronic pelvic pain, overactive bladder, and number of physician visits during the 3-year follow up period. CONCLUSIONS Our study demonstrated an association between BPS/IC and a subsequent CHD diagnosis. We advise clinicians to screen subjects with BPS/IC for modifiable risk factors for CHD.

Abstract
AIMS Previous studies indicated a possible association between bladder pain syndrome/interstitial cystitis (BPS/IC) and sleep disorders including sleep abnormalities with delayed onset of sleep, waking up before needed, and snoring. Nevertheless, no previous study has reported the association between obstructive sleep apnea (OSA) and BPS/IC. In this retrospective cohort study, we examined the risk of BPS/IC among subjects with OSA during a 3-year follow-up in Taiwan using a population-based dataset. METHODS This study comprised 2,940 study subjects with OSA, and 29,400 randomly selected comparison subjects. We individually followed-up each sampled subject (n = 32,340) for a 3-year period to identify those subjects who subsequently received a diagnosis of BPS/IC. A Cox proportional hazards regression model was constructed to estimate the risk of subsequent BPS/IC following a diagnosis of OSA. RESULTS Incidences of BPS/IC during the 3-year follow-up period were 13.61 (95% confidence interval [CI] = 7.37-23.13) and 3.60 (95% CI = 2.06-4.39) for subjects with and those without OSA, respectively. After adjusting for diabetes, hypertension, coronary heart disease, obesity, hyperlipidemia, chronic pelvic pain, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, depression, panic disorder, migraines, sicca syndrome, allergies, endometriosis, asthma, tobacco use disorder, and alcohol abuse, the stratified Cox proportional hazards regressions revealed that the hazard ratio for BPS/IC among subjects with OSA was 3.71 (95% CI = 1.81-7.62, P < 0.001) that of comparison subjects. CONCLUSIONS This study provides epidemiological evidence of a link between OSA and a subsequent BPS/IC diagnosis. We suggest that clinical practitioners treating subjects with OSA be alert to urinary complaints in this population.

Abstract
BACKGROUND Using a comprehensive questionnaire the care situation of 270 patients with interstitial cystitis (IC) and bladder pain syndrome in Germany was recorded. Despite comprehensive literature on IC (62,000 citations in PubMed) almost nothing is known of the everyday care and quality of patient care in Germany. RESULTS In total 94% of the patients were women and 6% men, the average age of women was 53.5 years and that of men 67 years and 47.77% of the patients felt that they were well or very well informed about the disease whereby the internet was the source of information in many cases. The exchange of information among patients will increase further through social networks. The diagnosis of IC was made most frequently (62.22%) by biopsy and histological examination followed by urodynamics, potassium test, hydrodistension and cystoscopy. The average duration of the diagnosis was 9 years, 46.67% of the patients consulted a doctor more than 20 times before the diagnosis was made and 51.84% had to pass water more than 14 times per day. Frequency, nocturia and pain were the leading symptoms and 25% of the patients complained of urge incontinence. Among oral medications, analgesics were taken most frequently (61.7%) followed by pentosan polysulphate, antidepressants, antiepileptic drugs, antispasmodics and remedies for urinary urgency. In the self-assessment of the success of treatment with oral medications (helped very well and well), pentosan polysulphate, analgesics, antidepressants and antiepileptic drugs were considered to be the best. Medications that restore the glucosamine lining of the bladder were used predominantly for instillation into the bladder included hyaluronic acid, chondroitin sulphate and a combination of both and pentosan polysulphate. In the self-assessment of the success of treatment with instillation therapy (helped very well or well) the order was: chondroitin sulphate (62.69%), hyaluronic acid (55.77%), a combination of both (53.66%) and pentosan polysulphate (46.30%). The electromotive drug administration (EMDA) procedure with the use of direct current to introduce medications into the bladder wall was mentioned surprisingly often, namely, in 119 patients. In the self-assessment success (helped very well or well) was considered the best for intravesical procedures with 61.34%. CONCLUSIONS Compared with all drug procedures instillation of medications into the bladder was mentioned 368 times and was assessed by the patients as having helped very well and noticeably by 53.53%, followed by special invasive procedures at 50.56%/271 mentions, alternative therapies at 41.11%/287 mentions and oral medication at 39.75%/1,024 mentions. Hyaluronic acid and chondroitin sulphate products, the combination of both and pentosan polysulphate (oral and intravesical) are not reimbursed by the statutory health insurance. Over 40% of patients treated with these therefore discontinued the treatment for reasons of cost.

Abstract
INTRODUCTION AND HYPOTHESIS The bladder pain syndrome (BPS) is a spectrum of urological symptoms characterised by bladder pain with typical cystoscopic features. Diagnosis and management of this syndrome may be difficult. There is no evidence-based management approach for the diagnosis or treatment of BPS. The objective of this study was to critically review and summarise the evidence relating to the diagnosis and treatment of the bladder pain syndrome. METHODS A review of published data on the diagnosis and treatment of the BPS was performed. Our search was limited to English-language articles, on the "diagnosis", and "management" or "treatment" of "interstitial cystitis" and the "bladder pain syndrome" in "humans." RESULTS Frequency, urgency and pain on bladder filling are the most common symptoms of BPS. All urodynamic volumes are reduced in patients with BPS. Associated conditions include psychological distress, depression, history of sexual assault, irritable bowel syndrome and fibromyalgia. Cystoscopy remains the test for definitive diagnosis, with visualisation of haemorrhage on cystoreduction. A multidisciplinary treatment approach is essential in the management of this condition. Orally administered amitriptyline is an efficacious medical treatment for BPS. Intravesical hyaluronic acid and local anaesthetic, with/without hydrodistension are among new treatment strategies. Sacral or pudendal neuromodulation is effective, minimally invasive and safe. Surgery is reserved for refractory cases. CONCLUSIONS There remains a paucity of evidence for the diagnosis and treatment of BPS. We encountered significant heterogeneity in the assessment of symptoms, duration of treatment and follow up of patients in our literature review.

Abstract
Our understanding of interstitial cystitis/painful bladder syndrome (IC/BPS) has evolved with the advancements in our understanding of visceral pain syndromes. The concept of IC/BPS as a visceral pain disorder is used as a model to base a targeted approach to the management of patients with IC/BPS. Guidelines for the treatment of both the bladder and nonbladder pain disorders are reviewed.

Abstract
BACKGROUND Irritable bowel syndrome and other gastrointestinal (GI) and non-GI disorders such as functional dyspepsia, fibromyalgia, temporomandibular joint disorder, interstitial cystitis/painful bladder syndrome, and chronic fatigue syndrome are known as functional pain syndromes. They commonly coexist within the same individual. The pathophysiologic mechanisms of these disorders are not well understood, but it has been hypothesized that they share a common pathogenesis. PURPOSE The objective of this review is to discuss the proposed pathophysiologic mechanisms, which have been similarly studied in these conditions. These mechanisms include enhanced pain perception, altered regional brain activation, infectious etiologies, dysregulations in immune and neuroendocrine function, and genetic susceptibility. Studies suggest that these functional disorders are multifactorial, but factors which increase the vulnerability of developing these conditions are shared.

Abstract
UNLABELLED Study Type--System prevalence (cohort) Level of Evidence 2a. What's known on the subject? and What does the study add? Compared with the general population, patients with BPS/IC often experience difficulties in performing normal activities owing to physical limitations, decreased energy, greater pain and impaired social functioning With the exception of metastatic cancer, separate conditional logistic regression analyses in this study suggested that subjects with BPS/IC were consistently more likely than subjects without BPS/IC to have all the medical comorbidities investigated. When compared with subjects without BPS/IC, subjects with BPS/IC had particularly higher odds of comorbid neurological diseases, rheumatological diseases and mental illnesses. OBJECTIVE • To explore the comorbid medical conditions of patients with bladder pain syndrome/interstitial cystitis (BPS/IC) in Taiwan using a cross-sectional study design and a population-based administrative database. SUBJECTS AND METHODS • The study included 9269 subjects with BPS/IC and 46,345 randomly selected comparison subjects. • Conditional logistic regression analyses were performed to calculate the odds ratio for each of the 32 medical comorbidities (hypertension, congestive heart failure, cardiac arrhythmias, blood loss anaemia, peripheral vascular disorders, stroke, ischaemic heart disease, hyperlipidaemia, hepatitis B or C, migraines, headaches, Parkinson's disease, rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, pulmonary circulation disorders, chronic pulmonary disease, diabetes, hypothyroidism, renal failure, fluid and electrolyte disorders, liver diseases, peptic ulcers, deficiency anaemias, depressive disorder, psychoses, metastatic cancer, solid tumour without metastasis, alcohol abuse, drug abuse and asthma) between subjects with and without BPS/IC. RESULTS • With the exception of metastatic cancer, the subjects with BPS/IC had a significantly higher prevalence of all the medical comorbidities analysed than subjects without BPS/IC. • With the exception of metastatic cancer, separate conditional logistic regression analyses suggested that subjects with BPS/IC were consistently more likely than subjects without BPS/IC to have any of the medical comorbidities investigated in this study. • When compared with subjects without BPS/IC, subjects with BPS/IC had particularly higher odds of comorbid neurological diseases, rheumatological diseases and mental illnesses. CONCLUSION • Our results indicated that subjects with BPS/IC had an increased prevalence of multiple comorbidities.
