Intravesical resiniferatoxin for the treatment of interstitial cystitis: a randomized, double-blind, placebo controlled trial

PURPOSE: Interstitial cystitis is a painful bladder condition of unknown etiology and poorly understood pathophysiology. Current therapies have met with limited success. Vanilloid receptor agonists such as resiniferatoxin (RTX) desensitize C-fibers that transmit pain; it is hypothesized that such drugs will be effective in the treatment of interstitial cystitis and painful bladder syndrome by decreasing the pain that leads to urinary frequency and urgency. MATERIALS AND METHODS: A randomized, double-blind, placebo controlled study was conducted in 163 patients with interstitial cystitis. Participants were randomly assigned to receive a single intravesical dose of 50 ml of either RTX 0.01 microM, 0.05 microM, 0.10 microM, or placebo. Safety and efficacy was evaluated over 12 weeks. The primary efficacy endpoint was the Global Response Assessment, a 7-point scale rating overall change in symptoms of interstitial cystitis after 4 weeks. Secondary efficacy endpoints included reduction in pain, urgency, frequency, nocturia, average void volume, and the O'Leary-Sant Symptom and Problem Indexes. RESULTS: RTX did not improve overall symptoms, pain, urgency, frequency, nocturia, or average void volume during 12 weeks followup. RTX resulted in a dose-dependent increase in the incidence of instillation pain, but was otherwise generally well tolerated. CONCLUSIONS: In the largest prospective, randomized clinical trial reported to date with intravesical vanilloid therapy, single administration of RTX at doses of 0.01 microM to 0.10 microM was not effective in patients with interstitial cystitis.     

Effect of intravesical Resiniferatoxin (RTX) on lower urinary tract symptoms, urodynamic parameters, and quality of life of patients with urodynamic increased bladder sensation

OBJECTIVES: Intravesical resiniferatoxin (RTX) has been used with variable efficacy in the treatment of detrusor overactivity (DO). Patients with interstitial cystitis (IC) failed to benefit from this treatment, but a single placebo-controlled study in patients with non-IC painful bladders showed that RTX was effective in the short-term. We investigated the efficacy of intravesical RTX in patients with urgency and frequency due to increased bladder sensation. METHODS: Patients with intractable urgency and frequency, with or without urgency incontinence or bladder pain/discomfort, and with no urodynamic evidence of DO were recruited. After a single intravesical instillation of 100ml 50 nM RTX solution, patients were followed at 1, 3, and 6 mo for changes in urodynamics, bladder diary, the King's Health Questionnaire (KHQ), and degree of bladder pain. RESULTS: Fifteen patients (mean age, 52.5 yr) were treated. RTX significantly improved maximum cystometric capacity, volume at first desire to void, mean micturition volume, 24-h frequency, and daytime frequency for up to 6 mo after treatment. The overall KHQ score improved at all time points, with sustained improvements in the Symptom Severity, Incontinence Impact, and Personal Relationships domains. A >50% decrease in pain was reported by five of seven patients with painful bladders at 1 mo, but only one of seven at 6 mo. CONCLUSIONS: In our small open-label study, a single administration of intravesical RTX in patients with frequency and urgency due to increased bladder sensation significantly improved lower urinary tract symptoms, urodynamic parameters, and quality of life for up to 6 mo.     

Anesthetic management of patients with interstitial cystitis during intravesical resiniferatoxin therapy

The management of patient with interstitial cystitis (IC) remains a challenge because no single agent has proven effective. IC is a chronic sterile inflammatory disease of the bladder of unknown etiology characterized by urinary frequency, urgenecy, nocturia and lower abdominal pain. We experienced anesthetic management of five patients with IC during intravesical resiniferatoxin (RTX) therapy. RTX is associated with irritative urinary symptom during bladder instillation. The patients with IC had bladder instillation with 100 ml of 10(-8) M RTX solution for 30 min. The first patient received combined spinal-epidural anesthesia (CSEA), and the others general anesthesia. The patient with regional anesthesia had no critical troubles related to circulatory status during the procedure, but increases of blood pressure after instillation of RTX were observed in two patients receiving general anesthesia. In spite of the increase in blood pressure during general anesthesia, regional anesthesia should not be used, because the effect of RTX on the spinal cord has to be maintained.     

Multiple intravesical instillations of low-dose resiniferatoxin in the treatment of refractory interstitial cystitis

BACKGROUND: Current medications used in the treatment of interstitial cystitis (IC) have limited efficacy. This prospective study investigated the efficacy of multiple intravesical instillations of resiniferatoxin (RTX) at the concentration of 10 nM. METHODS: Patients with proven IC previously treated with traditional medications for more than 6 months without clinical benefit were enrolled. They were excluded if bladder outlet obstruction or urinary tract infection was present. Intravesical instillation of low-dose RTX (10 nM) once weekly for 4 weeks was performed at the outpatient department. International Prostate Symptom Score (IPSS), 5-Point Pain Scale, and Quality of Life Index (QOL Index) were recorded. A videourodynamic study was done at baseline and 3 months after treatment. RESULTS: The therapeutic results and urodynamic parameters were compared between baseline and 3 months. Thirteen patients, including 10 women and 3 men, were enrolled in this study. The mean duration of IC symptoms was 4.4 +/- 2.5 years. The mean duration of active treatment was 15.3 +/- 8.6 months. One female patient dropped out due to severe bladder pain after RTX instillation. Among the 12 patients who completed the study treatment, subjective assessment revealed that 2 had an excellent therapeutic result, 5 had an improved result and 5 remained unchanged from baseline. The overall satisfactory rate was 58.3%. IPSS, 5-Point Pain Scale, and QOL Index were significantly decreased after RTX treatment. There was no significant increase in mean functional bladder capacity or change in urodynamic parameters. No serious adverse event occurred after RTX treatment. CONCLUSIONS: This study suggests that multiple intravesical instillations of RTX at the concentration of 10 nM are effective in relieving lower urinary tract symptoms in patients with refractory IC. The treatment is tolerable and suitable for use on an outpatient clinic basis.     

Bladder necrosis following hydrodistention in patients with interstitial cystitis

PURPOSE: Bladder hydrodistention is used to diagnose and treat patients with interstitial cystitis. This procedure has been shown to have minimal morbidity and provide symptomatic relief in a subset of patients with interstitial cystitis. We report our experience with almost total bladder necrosis after hydrodistention at 2 institutions. To our knowledge this rare complication has not been previously reported in the literature. We also reviewed the literature regarding complications of hydrodistention and discuss their possible etiology. MATERIALS AND METHODS: We report 3 cases of bladder necrosis after therapeutic hydrodistention for interstitial cystitis at 2 institutions. All records were reviewed, and the clinical presentation, findings and treatments are discussed. A literature review was performed to evaluate the effectiveness and complications of hydrodistention for interstitial cystitis. RESULTS: There were 2 female and 1 male patient between ages 29 and 46. All patients had a previous diagnosis of interstitial cystitis and had been previously treated with hydrodistention. All patients presented with severe abdominal pain and had necrosis of the entire bladder wall with sparing of the trigone. Two patients were treated with supratrigonal cystectomy. A review of the literature revealed little data on the effectiveness of hydrodistention for interstitial cystitis. CONCLUSIONS: Vesical necrosis is a rare but devastating complication of hydrodistention. It can occur in young patients in the absence of a contracted bladder and it usually presents as severe postoperative abdominal pain. At exploration bladder necrosis with sparing of the trigone was observed. All patients required enterocystoplasty.     

Interstitial cystitis in persistent posthysterectomy chronic pelvic pain.

OBJECTIVES: Hysterectomies may be performed unnecessarily in women with chronic pelvic pain if the diagnosis of interstitial cystitis is not considered. The objectives of this study were to investigate the prevalence of interstitial cystitis in patients with posthysterectomy chronic pelvic pain and to evaluate the efficacy of various therapies for interstitial cystitis. METHODS: A study was performed of 111 patients with chronic pelvic pain whose pain persisted after hysterectomy. Patients were screened with the Pelvic Pain and Urgency/Frequency symptom scale, and underwent Potassium Sensitivity Testing. Patients were treated with dietary changes alone or in combination with cystoscopic hydrodistention or oral pentosan polysulfate, or both of these, for 3 to 6 months. RESULTS: Of the 111 patients enrolled, 79% (n=88) were diagnosed with bladder dysfunction consistent with interstitial cystitis. For patients treated with dietary modification alone (n=33), the mean score on the Pelvic Pain and Urgency/Frequency questionnaire improved 15.4%, from 13.18 at baseline to 11.15 at follow-up. For patients treated with pentosan polysulfate or cystoscopic hydrodistention, or both, plus diet changes (n=78), Pelvic Pain and Urgency/Frequency scores improved 34.2%, from 15.01 to 9.87. CONCLUSION: In this study, nonsurgical treatment for interstitial cystitis resulted in a marked improvement in symptoms that had not improved with surgery. Without determining the origin of bladder pain, gynecologists should not proceed to hysterectomy in patients with chronic pelvic pain.     

Hydrodistention of the bladder in patients with interstitial cystitis--clinical efficacy and its association with immunohistochemical findings for bladder tissues

We retrospectively analyzed the clinical relevance of hydrodistention under anesthesia for patients having urgency and/or lower abdominal pain who were clinically diagnosed as having interstitial cystitis (IC) from May 1996 to May 2005. Their symptoms were refractory to anticholinergic or antiinflammatory agents. Hydrodistention was performed under general or spinal anesthesia with direct vision by cystoscopy and irrigation fluid was instilled into the bladder at a pressure of 80 cmH2O. Cystoscopic findings revealed glomerulation in 26 patients (96%), cracking in 10 (37%) and Hunner's ulcer in 3. Twenty-four patients (89%) obtained improvement of the objective symptoms after treatment. However, symptoms soon deteriorated in 16 patients, and the average duration of efficacy was only 4.7 months (SD; +/-3.7). There were two episodes of complication in this treatment. Bladder rupture occurred during hydrodistention, but was successfully managed with simple percutaneous perivesical drainage. One patient with acute pyelonephritis was treated with an antimicrobial agent without any additional treatment. Although bladder specimens were examined by immunohistochemistry, tryptase and c-kit were not linked with the mast cell count, severity of symptoms or treatment efficacy. Hydrodistention of the bladder may be recommended as the first treatment choice for patients with IC because it provides relatively high efficacy. However, the short duration of the efficacy requires a second-line treatment option for better management of patients with IC.

Von der Endorganerkrankung zum klassifizierbaren Blasenschmerzsyndrom

Growing clinical and scientific data imply that the condition currently called interstitial cystitis is not just a mere bladder end-organ disease but that the symptoms perceived to be related to the bladder are rather one aspect of a complex pelvic pain syndrome. The term bladder pain syndrome/interstitial cystitis (BPS/IC) suggested by the European Society for the Study of IC/PBS (ESSIC) for this condition is currently the only one strictly consistent with the taxonomy guidelines of the European Association of Urology and the International Association for the Study of Pain. BPS would be diagnosed on the basis of chronic pelvic pain, pressure, or discomfort perceived to be related to the urinary bladder, accompanied by at least one other urinary symptom such as persistent urge to void or urinary frequency. Confusable diseases as the cause of the symptoms must be excluded. Classification of BPS types might be performed according to findings at cystoscopy with hydrodistention and morphologic findings in bladder biopsies. The end-organ condition interstitial cystitis has thus become a chronic pain syndrome with a predominantly neurovisceral pathophysiology. In daily practice, therapeutic approaches aiming at both the peripheral bladder urothelium and central nervous targets should be combined. A multimodal treatment strategy, such as the combination of tricyclic antidepressants with instillation therapy, still appears reasonable and justified.     

Role of cystoscopy and hydrodistention in the diagnosis of interstitial cystitis/bladder pain syndrome

There are controversies about whether cystoscopy with or without hydrodistention (HD) plays a role in the diagnosis and treatment of interstitial cystitis/bladder pain syndrome (IC/BPS). We reviewed the recommendations of various societies and associations of greater impact in this complex disease, analyzing the indications, technique, findings and complications of this procedure.     

A rational combination of intravesical and systemic agents for the treatment of interstitial cystitis

OBJECTIVE: Interstitial cystitis is a condition with a poorly understood etiology and, consequently, various treatment options have been described in the literature, with a less than optimal outcome. The aim of this study was to examine the role of a combination of intravesical hydrocortisone and heparin, together with oral bladder sedatives and systemic triamcinolone, for the treatment of interstitial cystitis. MATERIAL AND METHODS: A total of 26 patients who were diagnosed as having interstitial cystitis were treated with weekly intravesical hydrocortisone (200 mg) and heparin (25,000 IU) in physiological saline for 6 weeks. In addition, they were given oral bladder sedatives such as oxybutynin or tolterodine. Ulcerative, refractory and recurrent cases were treated with intramuscular triamcinolone (40 mg) weekly for 6 weeks. RESULTS: All patients experienced an improvement in symptoms within 48 h of their first intravesical instillation. While 19 patients (73%) experienced almost complete pain relief, five of the remaining seven patients improved with intramuscular triamcinolone. Frequency reduced from a mean of 23.2 to 10.9 voids per day and was acceptable in 21 patients (80%). Six patients (23%) had a relapse of symptoms in the form of pain and were treated satisfactorily by means of intramuscular triamcinolone. The mean duration of follow-up was 18.3 months. CONCLUSION: A combination of intravesical hydrocortisone and heparin, along with oral bladder sedatives and systemic steroids, has been used with encouraging results in a small group of patients with interstitial cystitis.     

Interstitial cystitis and endometriosis in patients with chronic pelvic pain: The "Evil Twins" syndrome.

OBJECTIVE: To determine the prevalence of interstitial cystitis and endometriosis in patients with chronic pelvic pain. METHODS: A prospective analysis was conducted in 178 women with CPP who presented with bladder base/anterior vaginal wall and/or uterine tenderness, with or without irritative voiding symptoms. The Potassium Sensitivity Test was used to assess bladder epithelial dysfunction. Patients were evaluated with concurrent laparoscopy and cystoscopy with hydrodistention. RESULTS: Laparoscopic findings among the 178 patients with chronic pelvic pain supported a diagnosis of endometriosis in 134 (75%) patients, and cystoscopy confirmed a diagnosis of interstitial cystitis in 159 (89%) patients. Both interstitial cystitis and endometriosis were diagnosed in 115 patients (65%). The Potassium Sensitivity Test was positive in 146 (82%) patients, with 140 (96%) of these patients diagnosed with interstitial cystitis and 105 (72%) with endometriosis. CONCLUSIONS: Results of this prospective study show that interstitial cystitis and endometriosis may frequently coexist in patients with chronic pelvic pain. A positive Potassium Sensitivity Test accurately predicted the presence of interstitial cystitis in 96% of these patients with chronic pelvic pain, as confirmed by cystoscopic hydrodistention. It is necessary to consider the diagnosis of endometriosis and interstitial cystitis concurrently in the evaluation of patients with chronic pelvic pain to avoid unnecessary delay in identifying either condition.

Review of intravesical therapies for bladder pain syndrome/interstitial cystitis

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.

Bladder stretch alters urinary heparin-binding epidermal growth factor and antiproliferative factor in patients with interstitial cystitis

PURPOSE: The etiology of interstitial cystitis is unknown. Urine from patients with interstitial cystitis has been shown to inhibit urothelial proliferation through a putative antiproliferative factor and to contain decreased levels of heparin-binding epidermal growth factor-like growth factor (HB-EGF) compared to controls. Stretch of detrusor smooth muscle cells is known to stimulate HB-EGF production. Because bladder hydrodistention sometimes alleviates the symptoms of interstitial cystitis, we determined whether the stretch stimulus of hydrodistention alters antiproliferative factor activity and/or HB-EGF in interstitial cystitis urine specimens. MATERIALS AND METHODS: Urine was collected immediately before, and 2 to 4 hours and 2 weeks after hydrodistention from 15 patients with symptoms and cystoscopic findings compatible with interstitial cystitis and 13 controls. Hydrodistention was performed with the subject under general or regional anesthesia and bladders were distended to 80 cm. water 3 times. Urinary HB-EGF was measured by enzyme-linked immunosorbent assay and urinary antiproliferative factor activity was determined by measuring 3H-thymidine uptake by normal human bladder urothelial cells. RESULTS: Hydrodistention significantly increased urinary HB-EGF in patients with interstitial cystitis toward normal control values (before distention p = 0.003, 2 weeks after distention p = 0.67). Urine antiproliferative factor activity decreased significantly after hydrodistention in patients with interstitial cystitis. However, antiproliferative factor activity in interstitial cystitis and control specimens was still statistically different 2 weeks after distention (before distention p = 0.0000004, 2 weeks after distention p = 0.04). CONCLUSIONS: Bladder stretch increased HB-EGF and conversely reduced antiproliferative factor activity in urine from patients with interstitial cystitis but not controls up to 2 weeks after distention. These results provide additional evidence for the possible role of antiproliferative factor and decreased HB-EGF in the pathophysiology of interstitial cystitis. To our knowledge this is also the first human study to show that in vivo bladder stretch can alter urinary factors that regulate cell growth.     

抗增殖因子活性测定对间质性膀胱炎的诊疗价值

Abstract：

Objective To approach the value of antiproliferative factor (APF) activity in the diagnosis and treatment of interstitial cystitis (IC). Methods Sterilitas urine specimens were harvested from 25 female patients with IC and 25 female normal controls. IC patients were treated with hydrodistention and subjected to irrigation of bladder with cystistat for 6 months. Sterilitas urine specimens and pelvic pain and urgency/frequency patient symptom scale (PUF) in IC group were determined before, and 3 and 6 months after treatment. Immunohistochemistry with AE1/AE3 was used to identify human bladder epithelial cells.Methylthiazol tetrazolium (MTT) assay was used to detect APF activity in patients with IC. Results There was significant difference in APF activity(F=396.798) and PUF (F=50.812) before and after treatment. Before treatment APF activity/PUF were significantly higher than those at the 3rd and 6th month post-treatment. There was a significant positive correlation between APF activity and PUF before and after treatment (rs =0.974, rs=0.836, rs=0.679). Conclusion There ia a significant positive correlation between APF activity and PUF. Urine APF activity can be used as an objective marker to diagnose IC and evaluate the curative effectiveness.
