Intravesical Instillation of Hyaluronic Acid With Epidermal Growth Factor for Restoring Urothelial Denudation and Alleviating Oxidative Stress in Lipopolysaccharide-Induced Interstitial Cystitis of Rats. Int Neurourol J 2024; 28:106-114. [PMID: 38956770 PMCID: PMC11222823 DOI: 10.5213/inj.2448028.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 05/29/2024] [Indexed: 07/04/2024] Open
Abstract
PURPOSE To investigate the efficacy of an intravesical instillation of hyaluronic acid (HA) combined with epidermal growth factor (EGF) for the treatment of interstitial cystitis (IC) using a lipopolysaccharide (LPS)-induced IC animal model. METHODS A total of 24 female Sprague-Dawley rats were randomized to 4 groups: sham control, IC, HA, and treatment (HA/ EGF) groups. A polyethylene-50 tube was placed inside the bladder of each animal. IC was induced by twice-weekly instillations of LPS for 3 weeks, which resulted in chronic injury of the urothelium. Animals in the sham control group only received saline instillation. Treatment solutions of HA and HA/EGF were given on days 0, 7, and 14 after IC induction (400 μL of HA in a concentration of 0.4 mg/0.5 mL and 400 μL of NewEpi, a commercialized HA/EGF mixture containing 2 μg of EGF and 0.4 mg of sodium hyaluronate). Animals were sacrificed on day 21 for further examinations. RESULTS The HA/EGF group showed visible improvement in hematuria with a significant reduction of red blood cells in the urine compared to the HA group. Histological examination revealed that HA/EGF treatment reversed the abnormalities developed in IC, including infiltration of inflammatory cells, irregular re-epithelialization, and fibrotic tissue. Moreover, HA/ EGF significantly reduced the levels of proinflammation cytokines (tumor necrosis factor-α, interleukin [IL]-6, and IL-1β) and substantially lowered the elevated oxidative stress biomarker malondialdehyde, yet restored the levels of antioxidant enzymes glutathione peroxidase and superoxide dismutase, with superior results than HA treatment. Cystometry studies indicated that HA/EGF significantly prolonged intercontraction interval and increased micturition volume. CONCLUSION HA/EGF has been demonstrated as a more effective treatment for enhancing the urothelium lining and reducing inflammatory changes to alleviate clinical symptoms associated with IC in rats, compared to HA alone.

Abstract
Given the recent evidence in the clinical application of regenerative medicine, mostly on integumentary systems, we focused our interests on recent bladder regeneration approaches based on mesenchymal stem cells (MSCs), platelet-rich plasma (PRP), and hyaluronic acid (HA) in the treatment of interstitial cystitis/bladder pain syndrome (IC/BPS) in humans. IC/BPS is a heterogeneous chronic disease with not-well-understood etiology, characterized by suprapubic pain related to bladder filling and urothelium dysfunction, in which the impairment of immunological processes seems to play an important role. The histopathological features of IC include ulceration of the mucosa, edema, denuded urothelium, and increased detection of mast cells and other inflammatory cells. A deeper understanding of the molecular mechanism underlying this disease is essential for the selection of the right therapeutic approach. In fact, although various therapeutic strategies exist, no efficient therapy for IC/BPS has been discovered yet. This review gives an overview of the clinical and pathological features of IC/BPS, with a particular focus on the molecular pathways involved and a special interest in the ongoing few investigational therapies in IC/BPS, which use new regenerative medicine approaches, and their synergetic combination. Good knowledge of the molecular aspects related to stem cell-, PRP-, and biomaterial-based treatments, as well as the understanding of the molecular mechanism of this pathology, will allow for the selection of the right and best use of regenerative approaches of structures involving connective tissue and epithelia, as well as in other diseases.

Abstract
Defects in the glycosaminoglycan layer (GAG) of the bladder mucosa have been identified as a significant contributor to the pathogenesis and clinical progression of chronic inflammatory diseases of the bladder, such as post-radiation cystitis, bladder pain syndrome and recurrent urinary tract infections. This narrative review aims to explore the contemporary evidence on the role of GAG reconstitution with intravesical installations of hyaluronic acid and chondroitin sulfate in the management of those patients, with a goal to provide valuable insights for clinical practice. The reviewed studies consistently demonstrate that GAG reconstitution can result in varying degrees of clinical improvement in patients with post-radiation cystitis, bladder pain syndrome and recurrent urinary tract infections, and is associated with a very favorable safety profile. While the available evidence is growing, its level is still limited, mainly by relatively low number of randomized controlled trials, with small sample sizes. Further research with larger, well-designed trials is needed to solidify the findings and optimize the clinical application of GAG reconstitution.

Abstract
Our understanding of interstitial cystitis/bladder pain syndrome (IC/BPS) has evolved over time. The diagnosis of IC/BPS is primarily based on symptoms such as urgency, frequency, and bladder or pelvic pain. While the exact causes of IC/BPS remain unclear, it is thought to involve several factors, including abnormalities in the bladder's urothelium, mast cell degranulation within the bladder, inflammation of the bladder, and altered innervation of the bladder. Treatment options include patient education, dietary and lifestyle modifications, medications, intravesical therapy, and surgical interventions. This review article provides insights into IC/BPS, including aspects of treatment, prognosis prediction, and emerging therapeutic options. Additionally, it explores the application of deep learning for diagnosing major diseases associated with IC/BPS.

Abstract
Our comprehension of interstitial cystitis/painful bladder syndrome (IC/PBS) has evolved over time. The term painful bladder syndrome, preferred by the International Continence Society, is characterized as "a syndrome marked by suprapubic pain during bladder filling, alongside increased daytime and nighttime frequency, in the absence of any proven urinary infection or other pathology." The diagnosis of IC/PBS primarily relies on symptoms of urgency/frequency and bladder/pelvic pain. The exact pathogenesis of IC/PBS remains a mystery, but it is postulated to be multifactorial. Theories range from bladder urothelial abnormalities, mast cell degranulation in the bladder, bladder inflammation, to altered bladder innervation. Therapeutic strategies encompass patient education, dietary and lifestyle modifications, medication, intravesical therapy, and surgical intervention. This article delves into the diagnosis, treatment, and prognosis prediction of IC/PBS, presenting the latest research findings, artificial intelligence technology applications in diagnosing major diseases in IC/PBS, and emerging treatment alternatives.

Abstract
Genitourinary syndrome of menopause (GSM) is a chronic condition affecting a large number of women, with a major impact on their urogenital health and sexual function. It occurs at midlife because estrogen levels decline with menopause enhancing aging-related changes of the functional anatomy of the urogenital system. Unfortunately, GSM may occur early in the lifespan of women or be exacerbated following anticancer treatments, such as chemotherapy, ionizing radiation, or surgical removal of reproductive organs. Symptoms of GSM are often under-reported by women, under-estimated and under-diagnosed by health care providers (HCPs), and subsequently under-treated, despite their profound negative impact on the quality of life. The mainstay of vaginal treatments is local estrogen therapy (LET) ensuring an effective management of moderate to severe symptomatic GSM. However, LET is generally contraindicated in women with a history of hormone receptor positive cancer, due to the fear of increased recurrence or possible interference with endocrine adjuvant therapies. Among non-hormonal treatments, hyaluronic acid-based moisturizers have shown promising clinical results both in healthy women and in cancer patients or survivors. Its strong water-binding properties provide lubricating and moisturizing effects, which contribute to maintaining a proper level of hydration and viscoelasticity in several body parts, including the urinary tract and genital tissues. Hyaluronic acid-based moisturizers are effective, safe, and well tolerated; therefore, they may represent a valid option for the early management of GSM-associated symptoms in every woman with a history of cancer who is unable or unwilling to undergo hormone-based therapies. Hence, the aim of this review was to provide an overview of GSM etiology and treatment in women with natural or iatrogenic menopause, with a focus on the use of hyaluronic acid as a prophylactic treatment in the context of an integrated management protocol for cancer patients.

Abstract
Urinary tract infections (UTIs) are a significant clinical problem that pregnant women and children commonly experience. Escherichia coli is the primary causative organism, along with several other gram-negative and gram-positive bacteria. Antimicrobial drugs are commonly prescribed to treat UTIs in these patients. Conventional treatment can range from using broad-spectrum antimicrobial drugs for empirical or prophylactic therapy or patient-tailored therapy based on urinary cultures and sensitivity to prospective antibiotics. The ongoing emergence of multi-drug resistant pathogens has raised concerns related to commonly prescribed antimicrobial drugs such as those used routinely to treat UTIs. Consequently, several natural medicines have been explored as potential complementary therapies to improve health outcomes in patients with UTIs. This review discusses the effectiveness of commonly used natural products such as cranberry juice/extracts, ascorbic acid, hyaluronic acid, probiotics, and multi-component formulations intended to treat and prevent UTIs. The combination of natural products with prescribed antimicrobial treatments and use of formulations that contained high amounts of cranberry extracts appear to be most effective in preventing recurrent UTIs (RUTIs). The incorporation of natural products like cranberry, hyaluronic acid, ascorbic acid, probiotics, Canephron® N, and Cystenium II to conventional treatments of acute UTIs or as a prophylactic regimen for treatment RUTIs can benefit both pregnant women and children. Limited information is available on the safety of natural products in these patients' populations. However, based on limited historical information, these remedies appear to be safe and well-tolerated by patients.

Abstract
Interstitial cystitis is an underdiagnosed chronic-relapsing to chronic-progressive urinary bladder disease, whose pathogenesis and aetiology has not been fully elucidated. The disease itself cannot be cured and treatment is symptomatic. Treatment options comprise conservative and medicinal approaches as well as a large number of interventional/surgical procedures. These include intravesical instillation, transurethral procedures such as injections of botulinum toxin A, corticosteroids and local anaesthetics, hydrodistension and neuromodulation as well as (laser) fulguration, resection and cystectomy. Although surgical procedures are considered a late option and are often referred to as last-resort therapy, these interventional options often show good to very good response rates, manageable complications and a favourable risk-benefit evaluation. An overall generalisation of surgery as a last-resort treatment option should therefore be avoided and its use should be discussed based on the individual needs of each patient.

Abstract
PURPOSE To assess the efficacy and safety of intravesical instillation of high molecular weight sodium hyaluronate (HMW-HA) for the treatment of radiation-induced cystitis. METHODS This prospective cohort study was conducted in seven centers in France. Eligible patients with radiation-induced cystitis were recruited between April 2020 and March 2021. A sterile disposable 50 ml prefilled solution containing 0.16% (80 mg/50 mL) HMW-HA (INSTYLAN) was instilled weekly into the bladder. The treatment consisted of 6 sessions (V1 to V6). Outcomes were assessed 1 week (V7) and 4 weeks (V8) after the last session and were compared with baseline (V0). The primary endpoint was bladder pain, evaluated by a Questionnaire with 5 closed-ended response options. Secondary endpoints included changes from baseline for hematuria, urinary frequency, and the effect of urgencies on Quality of Life (QoL). Adverse events (AEs) were graded according to the CTCAE 3.0 classification. RESULTS A total of 30 participants were enrolled. The Intent-to-Treat analysis showed a significant reduction in pelvic pain intensity (- 45.81%, p < 0.001), hematuria (- 26.87%, p = 0.008), total 24 h voids (- 23.92%, p < 0.001) and the effect of urgencies on QoL (- 33.92%, p < 0.001) at V7. The improvement for each outcome remained stable during the post-therapeutic period between V7 and V8. Bladder instillation therapy was well-tolerated: two treatment-related AEs (6.6%) were reported corresponding to two grade 1 hematuria. CONCLUSIONS Intravesical instillation of HMW-HA appears to be effective in the treatment of radiation-induced cystitis. Further comparative studies with longer follow-up are needed to confirm our preliminary results.

Abstract
Hyaluronan (HA) is a naturally occurring non-sulfated glycosaminoglycan (GAG), cell-surface-associated biopolymer and is the key component of tissue extracellular matrix (ECM). Along with remarkable physicochemical properties, HA also has multifaceted biological effects that include but not limited to ECM organization, immunomodulation, and various cellular processes. Environmental cues such as tissue injury, infection or cancer change downstream signaling functionalities of HA. Unlike native HA, the fragments of HA have diversified effects on inflammation, cancer, fibrosis, angiogenesis and autoimmune response. In this review, we aim to discuss HA as a therapeutic delivery system development process, source, biophysical-chemical properties, and associated biological pathways (especially via cell surface receptors) of native and fragmented HA. We also tried to address an overview of the potential role of HA (native HA vs fragments) in the modulation of inflammation, immune response and various cancer targeting delivery applications. This review will also highlight the HA based therapeutic systems, medical devices and future perspectives of various biomedical applications were discussed in detail.

Abstract
Abstract
Objective Intravesical glycosaminoglycans (GAG) treatment is one of the therapeutic options for chronic bladder pathologies and is approved for Bladder Pain Syndrome (BPS), radiation cystitis, and recurrent urinary tract infections (UTIs). The purpose of this study is to describe the demographic characteristics of patients with such pathologies in our population and to evaluate treatment response.
Methods It is a retrospective study of patients with the aforementioned pathologies, who received treatment with GAG. Demographic characteristics and subjective improvement with treatment were evaluated. A bivariate analysis was performed to study possible improvement predictors.
Results 53 patients were evaluated. Of them, 33 (62.3%) with BPS, 12 (22.6%) with recurrent UTIs, and 8 (15.1%) with radiation cystitis. The dose range received was between 4 - 20 instillations, with a median of 6 doses. 67.9% of patients showed improvement of symptoms with treatment, this percentage being even higher for the group of patients with recurrent UTIs (91%). No treatment response predictors were found.
Conclusions Intravesical GAG treatment is a therapeutic alternative for patients with chronic bladder pathologies, with satisfactory results in the medium term. Prospective studies are needed to support the findings of this study.

Abstract
Background: Radiotherapy (RT) is a choice to manage pelvic organ malignancies that can affect bladder; therefore, it causes radiation cystitis with some bothering urinary symptoms and decreasing the patient’s quality of life. Intravesical hyaluronic acid (HA) is an agent with promising results in some studies for cystitis, and Cystistat is a derivative of hyaluronic acid. Objectives: This clinical trial aimed at evaluating the effects of intravesical instillation of Cystistat on symptoms of radiation cystitis and quality of life (QOL). Methods: A total of 58 patients with radiation cystitis were randomized in 2 groups (case: 30, control: 28). One group received intravesical Cystistat, the other received normal saline weekly for up to 4 weeks and then monthly for up to 2 months. Hematuria, Visual Analog scale (VAS) and QOL based on King’s Health questionnaire were compared before and 3, 6 and 9 months after intravesical instillation. Results: The mean age of the patients was 63.93 ± 10.89 years old. The mean of each sub-category of QOL and total score of QOL, as well as, VAS score were significantly improved in comparison to the control group at each time of follow-ups (P < 0.05). Hematuria was significantly different in the 3rd, 6th and 9th month of follow-ups (P < 0.05). Conclusions: Findings showed that patients with radiation cystitis could significantly benefit from intravesical instillation of HA, their hematuria would be successfully resolved rather than control group in addition to lowering the VAS score, so their QOL would be improved.

Abstract
INTRODUCTION Glycosaminoglycans (GAGs) are involved in the pathogenesis of several urologic chronic diseases. Thus, GAGs replenishment therapy is widely reported as a therapeutic tool for chronic pelvic pain (CPP) conditions such as interstitial cystitis/bladder pain syndrome (IC/BPS) and prostate pain syndrome/chronic prostatitis. In this article we reviewed the current status of evidence on the clinic applications of glycosaminoglycans (GAGs) in the CPP. EVIDENCE ACQUISITION A literature search from inception was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement to identify clinical trials, randomized controlled trials, meta-analyses, and guidelines. EVIDENCE SYNTHESIS A total of 29 papers were identified regarding the use of GAGs in CPP. CONCLUSIONS GAGs replenishment therapy results are encouraging in chronic forms of pelvic pain even though well-powered randomized clinical trials are needed to better comprehend the exact role of this treatment.

Cells 2019; 8:cells8060523. [PMID: 31151306 PMCID: PMC6627752 DOI: 10.3390/cells8060523] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2019] [Revised: 05/23/2019] [Accepted: 05/23/2019] [Indexed: 12/26/2022] Open
Abstract
IBD98-M is a delayed-release formulation of mesalamine (mesalazine) and SH with a potential therapeutic role in ulcerative colitis (UC). A total of 51 patients with a modified Ulcerative Colitis Disease Activity Index (UCDAI) score of ≥4 and ≤10, and a modified UCDAI endoscopy subscore ≥1 were randomized for 6 weeks of double-blind treatment with IBD98 0.8 g/day or IBD 1.2 g/day or placebo. The efficacy and safety of IBD98-M in mild to moderate active UC were primarily evaluated. At week 6, 1 (5.9%), 2 (12.5%), and 2 (11.1%) patients receiving IBD98-M 0.8 g, IBD98-M 1.2 g, and placebo, respectively, (p > 0.999) achieved clinical remission. Higher clinical response was seen in IBD98-M 1.2 g (31.3%) versus placebo (16.7%) and endoscopic improvement in IBD98-M 0.8 g (29.4%) versus placebo (22.2%) was seen. Fecal calprotectin levels were reduced in IBD98-M groups versus placebo (p > 0.05). IBD98-M patients achieved significant improvement in physical health summary score component of the SF-36 (p = 0.01 and p = 0.03 respectively) compared to placebo. IBD98-M did not meet the primary end point but had higher clinical response (1.2 g/day) and endoscopic improvement (0.8 g/day) compared to placebo. The safety result shown that IBD98-M treatment was safe and well tolerated in this patient population. No new safety signals or unexpected safety findings were observed during the study. Further trials with different stratification and longer follow-up may be needed to evaluate the efficacy.

Abstract
INTRODUCTION Actinic cystitis (AC) is the manifestation of symptoms and signs following pelvic radiotherapy. Pelvic radiotherapy produces both acute and chronic damage and such damage may have a devastating impact on the quality and on the amount of life of the patient. OBJECTIVES To evaluate the number of radical cystectomies that have become necessary in the last five years in our department for AC after radiation treatment. MATERIALS AND METHODS From February 2012 to February 2017, 11 patients underwent "open" cystectomy for AC. All patients were studied with radiographic examinations and endoscopy prior to surgery. We retrospectively evaluated the type of primitive cancer, the radiation dose administered, the time between radiation treatment and cystectomy. We also studied the related symptoms that required surgery. RESULTS The mean age of patients at the time of cystectomy was 75 years. In six patients (54.4%) radiotherapy was performed for prostate cancer, for rectal cancer in two patients (18.1%), and for endometrial cancer in three patients (27.2%). Total radiant dose was different in different patients depending on the type and localization of cancer. The median time between radiotherapy and cystectomy was 111 months (24-256 months). All patients had symptoms before surgery. Seven patients (63.3%) with gross haematuria were treated with endoscopic clot evacuation and fulguration. DISCUSSION The first approach to patients with AC is often supportive care. Surgery remains the most invasive treatment in the management of those patients who are not responsive to conservative treatments.

Abstract
Objective Haemorrhagic cystitis (HC) is a relatively common complication of chemotherapy and radiotherapy to the pelvic area, but can be a challenging condition to treat, particularly since there is currently a lack of UK-led guidelines available on how it should optimally be defined and managed. Materials and methods A comprehensive literature search was undertaken to evaluate the evidence for the diagnosis, prevention and management of cancer treatment-induced HC. Results Recommendations and a proposed management algorithm for the diagnosis, prevention and treatment of HC, as well as the management of intractable haematuria, have been developed based on the expert opinion of the multidisciplinary consensus panel following a comprehensive review of the available clinical data. Conclusion These guidelines are relevant and applicable to current clinical practice and will help clinicians optimally define and manage this potentially serious condition.

Abstract
Bladder pain syndrome/interstitial cystitis (BPS/IC) is a chronic pain condition characterised by urinary frequency, urgency and pain or discomfort which the patient attributes to the bladder. It is a complex condition to manage and treat and requires a multi-disciplinary and multi-modal approach. As well as lifestyle and behavioural modifications, physical therapy and oral medications, intravesical treatments can be used in the treatment algorithm for BPS/IC. A number of intravesical agents are reviewed in this paper along with the available evidence for their use.

Abstract
BACKGROUND This is the first study performed to evaluate the effects of intravesical hyaluronic acid (IHA) instillation on diminishing the frequency of recurrent urinary tract infections (UTIs) in children. METHODS Fifteen children (10 girls, 5 boys) with recurrent UTIs were divided into two groups as either complicated (group 1) (with accompanying disorders including vesicoureteral reflux or neurogenic bladder) or uncomplicated patients (group 2). After administration of weekly four sessions of IHA therapy the patients were followed-up monthly for 2 years and classified as responsive (complete/partial) or unresponsive to treatment. RESULTS 53.3% of the patients with recurrent UTIs were complicated. In group 1 (n = 8), complete and partial response rates were 62.5% (n = 5) and 25% (n = 2), respectively. There was no response in 12.5% (n = 1) of the cases in group 1. In group 2 (n = 7), complete and partial response rates were 71.4% (n = 5) and 14.3% (n = 1), respectively. In this group, 14.3% (n = 1) of the patients were found to be unresponsive to IHA treatment. No side effects were observed in any of the patients. CONCLUSIONS IHA administration is considered as an effective treatment modality which significantly reduces the prevalence of or even provides complete recovery from recurrent UTIs in childhood. Therefore, it is believed that this approach can be used as a promising alternative to widespread use of antibiotics in this patient group.

Abstract
OBJECTIVE To verify the efficacy and safety of intravesical instillation of pirarubicin combined with hyaluronic acid after TURBT in non-muscle invasive bladder cancer patients. METHODS We conducted a prospective study recruiting 127 eligible patients from 2008 to 2010. Patients were randomly assigned to Group A (pirarubicin combined with hyaluronic acid) and Group B (pirarubicin alone). Patients' demographics, treatment efficacy on recurrence, visual analog scale score, and postoperative complications were evaluated and analyzed during observation. RESULTS After the first month of intravesical chemotherapy, a perceptible relief of pelvic pain and urinary symptoms was detectable in Group A when compared with Group B (Fig. 2; P = 0.04). From objective analysis, the clinicians observed a consistent better improvement in Group A than in Group B on clinical conditions (P = 0.02). Frequency, urgency, and odynuria are relieved effectively in Group A (21/64 32.9%) and in Group B (41/63 65.1%), with significant difference observed (P = 0.001). No statistical evidence of benefit was observed in terms of recurrence. No obvious hyaluronic acid-related adverse event was observed. CONCLUSIONS As compared to intravesical instillation of pirarubicin alone, the administration of pirarubicin combined with HA for prevention from postoperative recurrence was satisfactory and safe. The relief of pelvic pain and urinary symptoms is more rapid and more durable.

Abstract
Purpose To determine the efficacy of intravesical hyaluronic acid (HA) instillation in treating patients with refractory interstitial cystitis/painful bladder syndrome (IC/PBS) and to identify any related factors that influence its therapeutic effect. Methods Thirty-three female IC/PBS patients who demonstrated poor or unsatisfactory responses to previous treatments between December 2010 and October 2012 were enrolled. Despite previous treatments, the enrolled patients had visual analogue scale (VAS) pain scores ≥4 and total scores (symptom and bother scores) ≥13 on the pelvic pain and urgency/frequency (PUF) questionnaire and ≥12 on the O'Leary-Sant interstitial cystitis symptoms index (ICSI)/problems index (ICPI). All patients received once weekly intravesical instillations of 40-mg HA diluted in 50-mL saline for 4 weeks. The efficacy of the HA instillation was evaluated by comparing the mean changes in the scores of the VAS and questionnaires from baseline to 4 weeks after treatment. Improvement was defined as a ≥2 decrease in the VAS. Moreover, we investigated the effects of the presence of Hunner's ulcer and previous treatment modalities on the therapeutic outcome of HA instillation. Results The mean age was 57.0±1.8 years (range, 28-75 years). The VAS score significantly decreased from baseline to 4 weeks after treatment (-2.5, P<0.001). The mean changes in the PUF, ICSI, and ICPI from baseline to 4 weeks after the treatment were -3.8 (P<0.001), -2.3 (P<0.001), and -2.7 (P<0.001), respectively. Twenty patients (61%) showed improvements. Previous treatment modalities did not affect the efficacy of HA instillation and the presence of Hunner's ulcer was unrelated to outcomes. No complications were observed. Conclusions These results show that intravesical HA instillation is an effective and safe treatment for patients with refractory IC/PBS. Previous treatment modalities and presence of Hunner's ulcer do not affect the efficacy of HA instillation.

Abstract
To review the published data on predisposing risk factors for cancer treatment-induced haemorrhagic cystitis (HC) and the evidence for the different preventive and therapeutic measures that have been used in order to help clinicians optimally define and manage this potentially serious condition. Despite recognition that HC can be a significant complication of cancer treatment, there is currently a lack of UK-led guidelines available on how it should optimally be defined and managed. A systematic literature review was undertaken to evaluate the evidence for preventative measures and treatment options in the management of cancer treatment-induced HC. There is a wide range of reported incidence due to several factors including variability in study design and quality, the type of causal agent, the grading of bleeding, and discrepancies in definition criteria. The most frequently reported causal factors are radiotherapy to the pelvic area, where HC has been reported in up to 20% of patients, and treatment with cyclophosphamide and bacillus Calmette-Guérin, where the incidence has been reported as up to 30%. Mesna (2-mercaptoethane sodium sulphonate), hyperhydration and bladder irrigation have been the most frequently used prophylactic measures to prevent treatment-related cystitis, but are not always effective. Cranberry juice is widely cited as a preventative measure and sodium pentosanpolysulphate as a treatment, although the evidence for both is very limited. The best evidence exists for intravesical hyaluronic acid as an effective preventative and active treatment, and for hyperbaric oxygen as an equally effective treatment option. The lack of robust data and variability in treatment strategies used highlights the need for further research, as well as best practice guidance and consensus on the management of HC.

Abstract
INTRODUCTION AND HYPOTHESIS Glycosaminoglycan hyaluronic acid (HA) and chondroitin sulphate (CS) protect the urothelium. Damage to the urothelium may increase bacterial adherence and infection risk. This meta-analysis evaluated the effect of intravesical HA and HA and CS (HA-CS) combination therapy in recurrent bacterial cystitis (RBC) in adult women. METHODS A systematic literature search was performed. Primary outcomes were urinary tract infection (UTI) rate per patient-year, and UTI recurrence time (days). Secondary outcomes were 3-day voids and Pelvic Pain and Urgency/Frequency (PUF) symptom scale total score. RESULTS Four studies involving a total of 143 patients were retrieved and assessed in this analysis. Two were randomized, and two were nonrandomized. A significantly decreased UTI rate per patient-year [mean difference (MD) -3.41, 95 % confidence interval (CI) -4.33 to -2.49, p < 0.00001) was found. Similarly, pooled analysis showed a significantly longer mean UTI recurrence time (days) using either HA or HA-CS therapy (MD 187.35, 95 % CI 94.33-280.37, p < 0.0001). Two studies using HA and HA-CS therapy reported outcomes on 3-day voids, which were not significantly improved after therapy (MD -3.59, 95 % CI -8.43-1.25, p = 0.15), but a significantly better PUF total score (MD -7.17, 95 % CI -9.86 to -4.48, p < 0.00001) was detected in HA-CS groups. CONCLUSIONS Intravesical HA and HA-CS in combination significantly reduced cystitis recurrence, mean UTI recurrence time, and PUF total score. Study limitations include the small number of patients and possible bias. Further studies are needed to validate this promising treatment modality.

Abstract
OBJECTIVE Painful bladder syndrome/interstitial cystitis (PBS/IC) and recurrent urinary tract infections (UTI) are clinically challenging conditions to manage in patients. We evaluate the clinical use of intravesical sodium hyaluronate (Cystistat®) in both these patient groups who have completed treatment. PATIENTS AND METHODS Thirteen patients with recurrent UTIs (Group I) and 8 patients with PBS/IC (Group II) received intravesical sodium hyaluronate (Cystistat®). Preinstallation demographic parameters were statically comparable in both groups. The mean age of presentation was 54.6 years in Group I and 57.5 years in Group II (p = 0.9). All 13 patients in Group I were on low dose antibiotics. The mean number of installations completed in both groups was 9 (range 4-21). RESULTS Data was collected prospectively using a standard pre- and post-treatment questioner with the pelvic pain and urinary/frequency patient symptom scale. At a mean follow-up of 21 months a significant improvement in bladder pain (p = 0.05), daytime frequency (p = 0.03) and quality of life (p = 0.02) was noted in patients in Group I. Two patients had breakthrough UTIs during treatment. Within Group I, 7 (53%) patients responded well to treatment. Patients in Group II had a significant improvement in bladder pain (p = 0.02), urgency (p = 0.01), nocturia (p = 0.01) and quality of life (p = 0.04). Within Group II, 6 patients (75%) responded to treatment. CONCLUSION Intravesical sodium hyaluronate (Cystistat®) can be used with minimal side effects and good compliance in both groups of patients with PBS and recurrent UTIs. Longer follow-up and larger patient numbers in both groups will be required to confirm the long-term efficacy of these two clinically challenging groups of patients.

Abstract
AIMS Glycosaminoglycan (GAG) layer replenishment is a cornerstone in the therapy of interstitial cystitis (IC). During the last years intravesical GAG layer replenishment has proven to be an effective treatment for overactive bladder (OAB), radiation cystitis, and recurrent urinary tract infections (UTIs). METHODS Examination of different substances available for intravesical GAG replenishment and evaluation of the evidence for the treatment of the above-mentioned conditions. RESULTS We searched the Medical Literature Analysis and Retrieval System Online (MEDLINE) database for studies on intravesical GAG replenishment. A total of 27 clinical studies remain relevant to this topic, many of them with mixed patient selection and suboptimal definition of symptom improvement/success. Two placebo controlled studies with hyaluronic acid failed to show superiority and have not been published. One active controlled randomized study has been published showing that chondroitin sulphate 0.2% has a clear benefit for OAB patients. Another study with chondroitin sulphate 2.0% failed to show statistically significant evidence, but was underpowered. CONCLUSIONS A short number of randomized controlled studies confirm efficacy of intravesical GAG layer replenishment therapy. Concluded from the study background (which comprises also uncontrolled studies), so far chondroitin sulphate 0.2% is in favor for intravesical GAG layer replenishment therapy. In general, large-scale trials are urgently needed to underline the benefit of this type of therapy.

Abstract
INTRODUCTION AND HYPOTHESIS The glycosaminoglycan hyaluronic acid (HA) protects the urothelium; damage may increase bacterial adherence and infection risk. This study evaluated the effect of intravesical HA in recurrent bacterial cystitis (RBC). METHODS Women with RBC were randomized to intravesical HA 800 mg and chondroitin sulfate (CS) 1 g (IALURIL, IBSA) in 50 mL of saline solution once weekly for 4 weeks then once every 2 weeks twice more (group 1) or long term antibiotic prophylaxis using sulfamethoxazole 200 mg and trimethoprim 40 mg once weekly for 6 weeks (group 2; control). Evaluations included: cystitis recurrence at 2 and 12 months; subjective pain symptoms (visual analog scale [VAS]); 3 day voiding; sexual function; quality of life (King's Health Questionnaire [KHQ]); frequency symptoms/frequency symptoms (PUF symptom scale); and maximum cystometric capacity (MCC). Means ± standard deviations were reported, with Mann-Whitney test for between-group comparison (significance P < .05). RESULTS Of 28 women (mean age 60 ± 13 y) randomized, 26 completed follow-up (mean follow-up 11.5 mo). Group 1 showed a significant improvement in all evaluations; cystitis recurrence (1 ± 1.2 versus 2.3 ± 1.4, P = .02); 3-day voiding (mean 17.8 ± 3.5 vs 24.2 ± 8.3, P = .04); symptom VAS (1.6 ± 0.8 vs 7.8 ± 1.6, P < .001); PUF score (11.2 ± 2.7 vs 19.6 ± 2.2, P < .001), KHQ score (18.4 ± 7.2 vs 47.3 ± 13.6, P < .001), and MCC (380 ± 78 vs 229 ± 51 mL, P < .001) vs group 2 at 12 mo. No adverse effects were recorded. CONCLUSIONS Intravesical HA and CS in combination significantly reduced cystitis recurrence and improved urinary symptoms, quality of life, and cystometric capacity in RBC patients at 12 mo follow-up versus antibiotic prophylaxis. Study limitations include a small sample and relatively short follow-up.

Abstract
INTRODUCTION few studies have been carried out on therapeutic options in patients with painful bladder syndrome associated with interstitial cystitis. The aim is to verify the safety and effectiveness of treatment with sodium hyaluronate through intravesical instillation in patients with painful bladder syndrome. MATERIALS AND METHODS a series of 18 female patients is presented, with a mean age of 51 years and prior diagnosis of painful bladder syndrome, who were treated by means of the weekly infusion of an intravesical solution of 40mg of sodium hyaluronate in sterile solution, over a period of eight weeks. The patients were examined clinically and urodynamically prior to their inclusion in the study and eight months after the instillations had concluded. RESULTS there was a statistically significant improvement in the urodynamic parameters and in the symptoms measured quantitatively by means of the questionnaire "Pelvic Pain and Urgency/Frequency" between the baseline situation and after the vesical instillation of sodium hyaluronate in patients with painful bladder syndrome. There was no toxicity arising from the treatment, given that no adverse effects were recorded in relation to it. CONCLUSION the clinical use of intravesical hyaluronic acid in patients with painful bladder syndrome possibly associated with interstitial cystitis has been demonstrated. The clinical improvement is also associated both with increased bladder capacity and improved bladder sensitivity. Tolerance was excellent. Clinical tests that more profoundly evaluate the therapeutic potential of this drug in this type of patients are required.

Abstract
Painful bladder syndrome/interstitial cystitis (PBS/IC) is a chronic disease of unknown etiology characterized by vague bladder pain and nonspecific urinary symptoms, such as urgency and frequency. Although it was initially considered to be a rare condition, its prevalence has significantly increased, possibly because of different definitions used and greater physician awareness. Because of the multiple diagnostic criteria used, there is significant variation in its prevalence. In addition, there is often a delay in the diagnosis of PBS/IC. It affects predominantly women of middle age, and it significantly decreases quality of life. Diagnosis of PBS/IC is mainly a diagnosis of exclusion; there are no characteristic symptoms or pathognomonic findings. Therefore, it is important to rule out diseases that have a similar clinical picture (i.e., urinary infections, bladder carcinoma) but definite therapies and worse prognosis if left untreated. PBS/IC management suffers from lack of evidence; many therapies are empiric or based on small studies and case series. Treatment includes supportive therapies (psychosocial, behavioral, physical), oral treatments, and intravesical treatments, whereas other more invasive treatments such as electric neuromodulation and reconstructive surgery are reserved for refractory cases. Physicians should always keep in mind the diagnosis of PBS/IC in patients presenting with chronic urinary symptoms after excluding other more common diseases.

Abstract
OBJECTIVE To determine whether intravesical hyaluronic acid id effective in reducing the urinary frequency and pain associated with interstitial cystitis/painful bladder syndrome (IC/PBS). MATERIAL AND METHODS In a prospective, unblinded, uncontrolled pilot study, 20 patients (age range 34-80 years), all suffering from IC/PBS, received weekly bladder instillations of hyaluronic acid for 1 month and monthly instillations for a further 2 months. Patients were then offered further monthly instillations and all were subsequently evaluated after 3 years. Patient outcomes assessed were urinary frequency, use of analgesics and pain. RESULTS All patients completed the 3 months of hyaluronic acid treatment with mean decreases in nocturia and pain of 40% and 30%, respectively, and decrease in analgesic use. Thirteen patients (65%) responded to treatment (responders) and continued therapy, while seven patents withdrew, six because of a lack of response and one due to cystectomy. In the 13 patients who continued hyaluronic acid instillations, four complete responders(30%) ceased therapy after a strong positive response (36%, 60% and 81% decreases compared to baseline in day-time voids, night-time voids and scores, respectively) which was maintained in the absence of continuous therapy, while after 3 years seven partial responders (35%) were still on therapy (25% and 43% decreases compared to baseline in day-time voids and pain scores, respectively). Two patients developed other diseases during follow-up and showed no response to long-term therapy. Hyaluronic acid was will tolerated by all patients. CONCLUSION Hyaluronic acid safely reduced the pain and, to lesser degree, the urinary frequency associated with IC.

Abstract
OBJECTIVES Hyaluronic acid is a protective barrier of the urothelium. A damaged glycosaminoglycan layer may increase the possibility of bacterial adherence and infection. This damage is proposed to be a causative factor in the development of interstitial cystitis, common urinary tract infections, and hemorrhagic cystitis due to posthematopoietic stem cell transplantation. The aim of this article was to review the available data regarding the use of hyaluronic acid as an alternative treatment of the above-mentioned conditions. METHODS Articles relevant to our review that were archived by September 2006 were retrieved from PubMed. RESULTS Nine relevant studies were identified and evaluated. Hyaluronic acid was administered intravesically at a dose of 40 mg every week for 4-6 wk; patients with noted improvement received two additional monthly doses. Short-term responses of patients with interstitial cystitis, hemorrhagic cystitis, and recurrent urinary tract infections were 30-73% (7 studies), 71% (1 study), and 100% (1 study), respectively. The treatment was well tolerated except for occasional development of bacterial cystitis. The cost of each intravesical installation of hyaluronic acid is 120 UK pounds (excluding the cost of the urinary catheterization). CONCLUSIONS The available clinical data regarding the effectiveness of hyaluronic acid as a potential treatment of patients with interstitial cystitis, recurrent urinary tract infections, and hemorrhagic cystitis are limited. There is need for randomized controlled trials for further investigation of this important therapeutics question; these clinical trials should be disease-specific, blinded, and controlled, and of a sufficient number of patients. Until such studies are available, intravesical instillation of hyaluronic acid cannot be unquestionably endorsed for use for the aforementioned diseases.

Abstract
Painful bladder syndrome/interstitial cystitis (PBS/IC) is a disease of unknown aetiology, characterised by severe pressure and pain in the bladder area or lower pelvis that is frequently or typically relieved by voiding, along with urgency or frequency of urination in the absence of urinary tract infections. PBS/IC occurs primarily in women, is increasingly recognised in young adults, and may affect as many as 0.1-1% of adult women. PBS/IC is often comorbid with allergies, endometriosis, fibromyalgia, irritable bowel syndrome and panic syndrome, all of which are worsened by stress. As a result, patients may visit as many as five physicians, including family practitioners, internists, gynaecologists, urologists and pain specialists, leading to confusion and frustration. There is no curative treatment; intravesical dimethyl sulfoxide, as well as oral amitriptyline, pentosan polysulfate and hydroxyzine have variable results, with success more likely when these drugs are given together. Pilot clinical trials suggest that the flavonoid quercetin may be helpful. Lack of early diagnosis and treatment can affect outcomes and leads to the development of hyperalgesia/allodynia.

Abstract
Nephrogenic adenoma is a rare, benign lesion of the bladder, occurring as an epithelial response to chronic infection or trauma, probably arising from nephrogenic metaplasia. In contrast to nephrogenic adenomas in adults, who present with this tumor in the entire ureteral tract, it has been observed exclusively in the bladder of children thus far. We report and discuss here the case of a 12-year-old boy with diffuse calculus-producing nephrogenic adenoma successfully treated with sodium hyaluronate.

Abstract
OBJECTIVE To evaluate the efficacy of vesical instillation of hyaluronic acid against recurrent urinary tract infections. METHODS Twenty women with a history of recurrent urinary tract infections each received 9 intravesical instillations of hyaluronic acid over 6 months. Their status was assessed prospectively over 47.6 weeks and compared with a retrospective review of patient charts covering 36.2+/-6.2 weeks. RESULTS The total numbers of urinary tract infections were 67 before and 10 after treatment (p<0.001). Thirteen patients (65%) were free of recurrences until the end of the study. One had a recurrence during treatment, and 6 (30%) during follow-up. The number of infections per year per patient was reduced from 4.99+/-0.92 to 0.56+/-0.82 (p<0.001). In women with recurrences, time to recurrence was 178.3+/-25.5 days, compared with 76.7+/-24.6 days before treatment (p<0.001). CONCLUSION Intravesical instillation of hyaluronic acid is effective in preventing recurrent urinary tract infections.

Abstract
PURPOSE To assess the impact of bladder instillations of hyaluronic acid (HA) on the prevalence of urinary tract infection (UTI) in patients receiving emergency radiotherapy for metastatic spinal cord compression. METHODS AND MATERIALS Patients were recruited consecutively at one center and assigned to usual care (UC) (n = 34, mean age 62.2 years) or UC with once-weekly HA instillation (UC + HA) (Cystistat: 40 mg in 50 mL phosphate-buffered saline) (n = 37; mean age, 63.1 years). All patients had an indwelling catheter and received radiotherapy. UTI status was assessed at baseline and during hospitalization. RESULTS At baseline, patient groups were comparable, except for the prevalence of UTI at baseline, which was 11.8% and 0% in the UC and UC + HA patients, respectively (p = 0.0477). During hospitalization, 76.5% (vs. 11.8% at baseline, p < 0.0001) of the UC patients had a UTI compared with 13.5% (vs. 0% at baseline, p = 0.0541) of the UC + HA patients (p < 0.0001). Both groups were hospitalized for similar periods (19.8 days [UC] vs. 18.5 days, p = 0.4769) and received equivalent radiotherapy sessions (4.6 [UC] vs. 5.8 sessions, p = 0.2368). CONCLUSIONS Patients receiving UC + HA had a 5.7-fold decrease in UTI prevalence over the hospitalization period compared to UC patients, suggesting that bladder instillations of HA effectively prevent UTI in patients with indwelling catheters receiving radiotherapy for nerve compression.

Abstract
PURPOSE Substance P (SP) induces rat bladder inflammation along with release of the proinflammatory cytokine, macrophage migration inhibitory factor (MIF). To describe the mechanism of MIF action we examined changes in the amount of CD74 (membrane receptor for MIF), CD44 and phospho-(p-ERK)1/2 in the bladder. MATERIALS AND METHODS In anesthetized rats the bladder was isolated by cutting the ureters and urine was replaced by saline as intraluminal fluid (ILF). One hour after subcutaneous SP (40 mug/kg) or saline administration the ILF and bladder were collected. Bladder tissue was analyzed for CD74 and CD44 by immunohistochemistry. Western blot analysis determined the relative amounts of bladder tissue MIF, CD74, CD44 and p-ERK1/2. ILF immunoprecipitation followed by Western blot analysis was performed to identify an association of MIF with CD74 and/or CD44. RESULTS SP induced significant MIF release from the bladder and increased CD74 and CD44 bladder immunostaining. SP treatment increased the total amount of bladder CD74 protein and mRNA, intracellular domain CD44, p-ERK1/2 and soluble CD44 in the ILF. Finally, MIF was found to be associated with soluble CD44 in the ILF. CONCLUSIONS CD74 is present in the rat urothelium. SP increases CD74 and intracellular domain CD44 in the bladder, while stimulating the release of soluble CD44 and MIF into the ILF. MIF interacts with soluble CD44 in the ILF and it is available to bind with CD74 in the bladder to exert proinflammatory effects. Therefore, a mechanistic model is emerging to explain the proinflammatory effects of MIF in this acute model of bladder inflammation. Possible clinical implications are discussed.

Abstract
PURPOSE To examine the site, severity, and duration, of symptoms in patients with interstitial cystitis. To examine the treatments offered. MATERIALS AND METHODS Postal questionnaire administered to members of the Interstitial Cystitis Support Group, based in the United Kingdom. RESULTS 736 of 1148 (64%) questionnaires were returned. 696 (94.6%) patients were women. 471 patients (64%) described daily pain when symptoms were at their worst, and 273 (37%) described daily pain at the time of survey. Most patients reported frequency, urgency and nocturia. A wide range of treatments had been offered, but drugs of proven efficacy were offered to less than a third of patients: cimetidine (36%); antihistamines (5%); pentosan polysulphate (12%); DMSO (33%); and anticonvulsants (2%). 495 patients (67%) reported "considerable impact" or more on their lifestyle and 346 (46%) reported moderate depression or worse. 364 (49%) reported at least considerable difficulties with sexual intercourse. CONCLUSIONS This survey supports the work of others about the nature of symptoms and their impact upon quality of life. The data highlight the continuing difficulty in making a prompt diagnosis. We recommend that a European survey or registry of interstitial cystitis patients would help to establish a minimum standard of care. A suggested treatment algorithm is provided.

Abstract
Oral glucosamine was compared to a placebo for the management of cats with feline idiopathic cystitis (FIC) in a randomised, double-blinded, placebo-controlled, study. Forty cats with a history of recurrent cystitis due to FIC were divided into two groups and treated daily per os with either 125 mg N-acetyl glucosamine or a placebo for six months. Owners graded their cats' clinical signs at the beginning and end of the study, and kept daily diaries documenting signs of cystitis using visual analogue scales. Further episodes of cystitis were seen in 26 (65%) of the cats during the study. Affected cats experienced a mean of five recurrences (range 1-19) with each recurrence lasting a mean of four days (range 1-64 days). There were no significant differences between the two groups when considering the owners assessments of the mean health score (P>0.5), the average monthly clinical score (P=0.22) or the average number of days with clinical signs (P=0.28). Two cats suffered from such severe recurrent urethral obstruction that they were euthanased; they were both in the placebo group. Compared to the start of the study the majority of cats in both groups improved significantly (P<0.001) (mean health score of each group at the start was 0.5+/-SD 0.5, compared to glucosamine 4.4+/-0.7 and placebo 3.9+/-1.6 at the end). This is believed to have occurred because the owners of 36 of the 40 cats (90%) started feeding more canned cat food. The urine specific gravity at the start of the trial was significantly higher (mean 1.050+/-SD 1.007) than when reassessed one month later (1.036+/-1.010, P<0.01).
