Abstract
OBJECTIVES To improve diagnosis of IC/BPS(IC) we hereby developed an improved IC risk classification using machine learning algorithms. METHODS A national crowdsourcing resulted in 1,264 urine samples consisting of 536 IC (513 female, 21 male, 2 unspecified), and 728 age-matched controls (318 female, 402 male, 8 unspecified) with corresponding PRO pain and symptom scores. In addition, 296 urine samples were collected at three academic centers: 78 IC (71 female, 7 male) and 218 controls (148 female, 68 male, 2 unspecified). Urinary cytokine biomarker levels were determined using Luminex assay. A machine learning predictive classification model, termed the Interstitial Cystitis Personalized Inflammation Symptom (IC-PIS) Score, that utilizes PRO and cytokine levels, was generated and compared to a challenger model. RESULTS The top-performing model using biomarker measurements and PROs (AUC=0.87) was a support vector classifier, which scored better at predicting IC than PROs alone (AUC=0.83). While biomarkers alone (AUC=0.58) did not exhibit strong predictive performance, their combination with PROs produced an improved predictive effect. CONCLUSIONS IC-PIS represents a novel classification model designed to enhance the diagnostic accuracy of IC/BPS by integrating PROs and urine biomarkers. The innovative approach to sample collection logistics, coupled with one of the largest crowdsourced biomarker development studies utilizing ambient shipping methods across the US, underscores the robustness and scalability of our findings.

Abstract
Purpose To determine intravesical instillation patterns among women receiving treatment for interstitial cystitis/bladder pain syndrome (IC/BPS). Methods Using the Veterans Affairs Informatics and Computing Infrastructure, active female users of the Veterans Affairs system with an ICD-9 diagnosis of IC/BPS (595.1) were randomly sampled. Patients were considered to have IC/BPS (by chart review) if they had two visits complaining of bladder-centric pain in the absence of positive urine culture ≥6 weeks apart or history of bladder pain with one additional visit for bladder-centric pain. We abstracted the dates of intravesical instillations for each patient. A "course" of instillations was defined as ≥1 instillations made with <21 days between visits. Results We identified 641 women with confirmed diagnosis of IC/BPS, 78 of whom underwent a total of 344 intravesical instillations. On average each subject had 1.5 +/- 0.8 courses between October 2004-July 2016. Each course was an average of 3.1 +/- 2.6 instillations. 55% of courses consisted of one instillation. Only 22% of courses had 6 or more instillations, the number typically recommended to achieve clinical response. Each instillation within a course was an average of 9.4 +/- 4.0 days apart. Most instillations (77%) were a cocktail of two or more drugs. Conclusions In our cohort, few women with IC/BPS received a recommended treatment course of six weekly instillations, with most receiving only one per course. Future studies are needed to determine if instillation courses were altered from the guideline due to provider practice patterns, early improvement, or poor tolerance of instillations.

Abstract
Objectives Pentosan Polysulfate (PPS) is the only oral treatment for interstitial cystitis (IC)-bladder pain syndrome (BPS) approved by the World Health Organization. Self-evaluation scales can provide more objective results on pre- and post-treatment satisfaction. The aim of this study was to investigate the effect of pentosan polysulfate treatment on symptoms in IC-BPS patients. Methods This study included 37 adult male and female patients with IC-BPS who reported pain, urinary urgency, polyurea, and nocturia without urinary tract infection for a minimum of six months prior to the study and were taking 300 mg/day oral pentosan polysulfate. Pre- and post-treatment symptoms, Interstitial Cystitis Symptom Index (ICSI) Scores, quality of life (QoL) scores (1-4), and satisfaction conditions were examined. Results Following the application of inclusion and exclusion criteria, mean age of 37 suitable patients was 46.0±11.9 years and 27% (10 individuals) of the patients were male. Pre-treatment, ICSI scores, and measures of satisfaction degree and QoL increased significantly after the treatment (p<0.001). Adverse reaction was detected in two patients (5.4%) among the patients treated with pentosan polysulfate. Conclusions Oral pentosan polysulfate for the treatment of interstitial cystitis/bladder pain syndrome treatment could achieve recovery in symptoms, increase Interstitial Cystitis Symptom Index score and improve quality of life and patient satisfaction.

Abstract
This review aims to assess the relationship between interstitial cystitis (IC) and significant traumatic events or PTSD. It was shown that there is a strong correlation between past trauma and the development of interstitial cystitis, as well as a much higher incidence of PTSD in patients diagnosed with IC. It was also established that for individuals with early traumatic experiences, the more likely the development of IC later in life, and with more severe symptoms and adverse effects on quality of life. We describe three distinct hypotheses for the possible physiologic mechanism for development of IC with relation to mental health and trauma, although definitive evidence in this area is still lacking, which poses interesting avenues for further research. This review also revealed an apparent lack of, and need for, trauma informed care and screening for PTSD in patients diagnosed with IC or other chronic pain syndromes.

Abstract
PURPOSE Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic debilitating condition of unknown etiology. Intravesical lidocaine demonstrated pain relief in patients with IC/BPS. Intravesical oxybutynin has shown therapeutic efficacy in patients with urinary bladder disorders. However, loss of drug with urination requiring multiple administrations and immediate dilution of drug concentration by residual urine in the bladder mitigated intravesical use of both drugs in clinical practice. The aim of this study was to evaluate the efficacy and safety of fixed-dose combination of lidocaine and oxybutynin, forming in the urine a sustained delivery system named TRG-042. MATERIAL AND METHODS In-vitro, we have quantitatively tested the concentration of lidocaine and oxybutynin released from TRG-042 in artificial urine. Following the successful in-vitro study weekly formulation of TRG-042 was instilled intravesically to six pigs. All pigs were followed with cystoscopy to assess the gradual degradation of the delivery system and to evaluate bladder response over 7 days. Daily blood samples were tested for drug quantization. RESULTS In-vitro studies have demonstrated oxybutynin and lidocaine sustained release over 1-week period coupled with full degradation of the matrix. None of the animals demonstrated any side effects following instillation. Cystoscopy examination observed gradual disintegration of TRG-042 over 1-week with no adverse reaction to the mucosa. Plasma concentrations of oxybutynin and lidocaine were uniformly stable over the 1-week period [1.46 ± 0.176 ng/ml and 4.29 ± 2.48 ng/ml respectively(mean ± SEM)] with almost undetectable concentration of N-desethyloxybutynin (NDO)[0.032 ± 0.068 ng/ml]. CONCLUSIONS The in-vitro and animal data demonstrated that TRG-042 can safely be used for intravesical sustained release of lidocaine and oxybutynin in the treatment of BPS/IC.

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
Objective: In the present study, we investigated the efficacy of bladder hydrodistension combined with pentosan polysulfate (PPS) treatment in interstitial cystitis (IC)/bladder pain syndrome (BPS). Methods: In this study, 339 patients diagnosed with IC/BPS were categorized into two groups. The first group only received 300 mg/day PPS, while the second group received 300 mg/day PPS following bladder hydrodistension. The results were evaluated at the 3rd, 6th, and 12th months after the first dose using the interstitial cystitis symptom index (ICSI), international cystitis problem index (ICPI), visual analog scale (VAS), and female sexual function index (FSFI). Results: PPS treatment started just after hydrodistension was significantly more effective than PPS treatment alone and combined treatment significantly reduced the rate of non-compliance such that, at the end of the 3rd month, 12.1% patients in Group-1 did not continue their treatment whereas only 1.9% of patients in Group-2 did not continue. Conclusions: The study results indicate that PPS treatment started just after hydrodistension yields significantly better results in terms of both symptom improvement and treatment compliance in patients with IC/BPS.

Abstract
Purpose Differences in the severity of subjective symptoms have been noted depending on whether a Hunner lesion is present in women with interstitial cystitis/bladder pain syndrome (IC/BPS). In this study, we aimed to identify differences in objective urodynamic parameters in women with IC/BPS according to the presence of a Hunner lesion. Methods This cross-sectional study included a total of 55 patients with IC/BPS. IC/BPS and the presence of a Hunner lesion on cystoscopy were diagnosed according to American Urological Association guidelines. The patients were categorized into a Hunner IC/BPS group and a non-Hunner IC/BPS group according to the presence of a Hunner lesion on cystoscopy. At the initial visit, a medical history was taken from all patients with IC/BPS, and they underwent symptom assessment using a 3-day voiding diary and laboratory tests. A urodynamic study was then performed before any treatment was performed. Baseline characteristics and urodynamic parameters were compared between the 2 groups. Results Of the 55 patients, 23 (41.8%) had a Hunner lesion on cystoscopy. As documented in the voiding diaries, the Hunner IC/BPS group had more frequent voids and a smaller maximal voided volume (P=0.045, P<0.001, respectively). Regarding urodynamic parameters, the mean volume at the first desire to void, normal desire to void, strong desire to void (SDV), and maximum cystometric bladder capacity (MBC) was significantly lower in the Hunner IC/BPS group (P=0.001, P=0.004, P<0.001, and P<0.001, respectively). On receiver operating characteristic curve analysis, patients with an SDV≤210 mL (area under the curve [AUC]=0.838, P<0.001) and an MBC≤234 mL (AUC=0.857, P<0.001) were likely to be in the Hunner IC/BPS group. Conclusions The differences in patients’ subjective symptoms between the Hunner IC/BPS and non-Hunner IC/BPS groups were confirmed to correspond to differences in objective urodynamic parameters.

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
The design of an early mobile health application (app) prototype to manage interstitial cystitis/painful bladder syndrome, a chronic condition characterized by recurrent pain/discomfort in the bladder and pelvic floor, is described. The purpose of this app prototype is to help people who have IC/PBS manage and learn what triggers their symptoms. Another aim of this research was to provide an example of how sex and gender could be included into the design of a health information system. Based on a literature search of common symptoms and challenges faced by people living with IC/PBS, the researcher created an app prototype design including many features: resources for relaxation, mental health, intimacy, pregnancy, and daily life; reminders for appointments, and medication; logs for diet, activity, sleep, pain, menstruation; and a link to a public washroom locator. This prototype will later undergo usability and content evaluation.

Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is characterized by bladder discomfort, urinary frequency, urgency, and pelvic pain. The etiology and pathogenesis of this condition is still unknown and remains diagnosed by exclusion. The histologic findings are also neither specific for diagnosis nor correlated with symptoms. However, the definition and diagnostic criteria for the condition was established in the last decade. In this paper, we review the changes in the definition, terminology, and diagnostic scheme of IC/BPS, and summarize the histologic findings. We also briefly discuss some new pathologic suggestions and new urinary markers, focusing on the most promising ones.

Abstract
Na(+)/K(+)-ATPase (NKA) is abundantly expressed in the basolateral membrane of epithelial cells, which is necessary for tight junction formation. The tight junction is an urothelial barrier between urine and the underlying bladder. Impairment of tight junctions allows migration of urinary solutes in patients with interstitial cystitis/painful bladder syndrome (IC/PBS). We evaluated NKA expression and activity in bladder samples from patients with IC/PBS. The study group consisted of 85 patients with IC/PBS, and the control group consisted of 20 volunteers. Bladder biopsies were taken from both groups. We determined the expression and distribution of NKA using NKA activity assays, immunoblotting, immunohistochemical staining, and immunofluorescent staining. The protein levels and activity of NKA in the study group were significantly lower than the control group (1.08 ± 0.06 vs. 2.39 ± 0.29 and 0.60 ± 0.04 vs. 1.81 ± 0.18 µmol ADP/mg protein/hour, respectively; P < 0.05). Additionally, immunofluorescent staining for detection of CK7, a marker of the bladder urothelium, predominantly colocalized with NKA in patients in the study group. Our results demonstrated the expression and activity of NKA were decreased in bladder biopsies of patients with IC/PBS. These findings suggest that NKA function is impaired in the bladders from patients with IC/PBS.

Abstract
A unique glycopeptide, antiproliferative factor (APF), has been suggested as a urinary biomarker and potential mediator of long-term bladder disorder Interstitial Cystitis/Painful Bladder Syndrome. There is no known cause for this disease. Several mechanistic approaches have been employed to address the underlying mechanism whereby APF regulates cellular responses in the bladder epithelium. A summary of recent literature is provided, and is focused on signal transduction pathways and networks that are responsive to APF.

Abstract
PURPOSE The objective of this study was to achieve a linguistic adaptation of the original version of the Pelvic Pain and Urgency/Frequency (PUF) Patient Symptom Scale into Korean. MATERIALS AND METHODS Between June 2008 and December 2008, a linguistic adaptation was carried out by 2 native Korean speakers who were also fluent in English. First, the original English version of the PUF was translated into Korean. A panel, which included the 2 translators, reviewed the translations to form a single reconciled forward translation of the Korean version. Then, another bilingual translator, having never seen the original version, back-translated the first draft of the Korean version of the PUF into English, and this back-translation was subsequently assessed for equivalence to the original. The panel discussed all discrepancies and produced a second version. After revising the 2nd version, 10 participants [5 interstitial cystitis (IC) patients and 5 persons from the general population], stratified variously by age, sex, and educational level, answered the PUF and were systematically debriefed afterwards. A summary of the changes from the patient interviews were incorporated into the third version. After the spelling, grammar, layout, and formatting were checked, the third version was verified as the final Korean version of the PUF, without modifications. RESULTS The multi-step process of forward translation, reconciliation, back-translation, cognitive debriefing, and proofreading of the Korean version of the PUF was completed. CONCLUSIONS The Korean version of the PUF scale may be helpful for screening IC patients in the Korean population and can now be used in Korea.
