hyaluronate Hyaluronan treatment of interstitial cystitis/painful bladder syndrome.
Riedl CR, Engelhardt PF, Daha KL, et al. Int Urogynecol J Pelvic Floor Dysfunct 2007 Dec 21 [Epub ahead of print]
• this study evaluated the efficacy of intravesical hyaluronan therapy in 126 patients with IC/PBS and mean disease duration of 6.1 years; to be eligible for hyaluronan treatment, a positive modified potassium test was requested as a sign of a urine-tissue barrier disorder
patients were treated with weekly instillations of a 50 ml phosphate-buffered saline solution containing 40 mg sodium hyaluronate
• data were obtained by a visual analogue scale (VAS) questionnaire rating from 0 to 10 that asked for global bladder symptoms before and after therapy; additional questions evaluated the therapeutic impact on quality of life
• 85% of the patients reported symptom improvement (2 or more VAS units); the mean initial VAS score of 8.5 decreased to 3.5 after therapy (p<0.0001); 55% remained with no or minimal bladder symptoms after therapy (VAS 0-2); 84% reported significant improvement of their quality of life
• intravesical therapy had to be initiated again with good success in 43 patients (34.5%) as symptoms recurred after discontinuation of treatment, while the rest stayed free of symptoms for up to 5 years
• in general, hyaluronan therapy was well tolerated and, with the exception of mild irritative symptoms, no adverse reactions were reported for a total of 1,521 instillations
• the authors conclude that timely hyaluronan instillation therapy may lead to complete symptom remission or even cure in part of the IC/PBS patients, while some responders need continuous intravesical therapy
• the present results suggest that selection of patients for hyaluronan therapy by potassium testing improves the outcome of intravesical therapy with a response rate of >80%
 
management review

Pharmacologic management of painful bladder syndrome/interstitial cystitis: a systematic review.
Dimitrakov J, Kroenke K, Steer WD, et al. Arch Intern Med 2007;167:1922-9
• over 180 different therapies have been tried for PBS/IC, yet evidence from trials remains inconclusive
• this study concludes that PPS may be modestly beneficial for PBS/IC
• there is insufficient evidence for other pharmacologic treatment
• a consensus on standardized outcome measures is urgently needed

• This review summarizes existing hypotheses about neural mechanisms underlying cross-sensitization in the pelvis.

 
intravesical treatment Intravesical treatments for painful bladder syndrome/ interstitial cystitis.
Dawson T, Jamison J. Cochrane Database Syst Rev 2007 Oct 17;(4):CD006113
• Cochrane report on intravesical treatment for PBS/IC
• Evidence base for intravesical treatment is limited
• Quality of trial reports mixed
• BCG and oxybutynin reasonably well-tolerated; RTX showed no evidence of effect for most outcomes
• Little evidence for other treatments included in this review
• Randomised controlled trials and standardisation are still needed

Shorter B, Lesser M, Moldwin RM, Kushner L. J Urol 2007;178:145-52

• patients with painful bladder syndrome/interstitial cystitis 90.2% indicated that the consumption of certain foods or beverages caused symptom exacerbation
• there was no correlation between allergies and the effect of comestibles on symptoms
• the most frequently reported and most bothersome comestibles were coffee, tea, soda, alcoholic beverages, citrus fruits and juices, artificial sweeteners and hot pepper
 
fibromyalgia bladder index The Fibromyalgia Bladder Index.
Brand K, Littlejohn G, Kristjanson L, et al. Clin Rheumatol 2007;26:2097-103
• the aim of this study was to determine whether the Interstitial Cystitis Symptom and Problem Index (ICSI/ICPI), is a valid, reliable, and clinically relevant instrument to assess the sensory urinary symptoms in women with fibromyalgia syndrome (FM)
• factor analysis displayed two separate components of symptom and problem combinations as distinct from the original ICSI/ICPI developed for the interstitial cystitis population
• the eight items of the index configured differently and formed two subscales of a newly developed Fibromyalgia Bladder Index
• the two subscales of this index include the Bladder Urgency and Pain Subscale and the Bladder Frequency and Nocturia Subscale.
 
ketamine Ketamine-Associated Ulcerative Cystitis: A New Clinical Entity.
Shahani R, Streutker C, Dickson B, Stewart RJ. Urology 2007;69:810-2
• ketamine is an anesthetic agent that is increasingly being used as a recreational drug
• the authors describe a series of 9 patients, all of whom were daily ketamine users, who presented with severe dysuria, frequency, urgency, and gross hematuria; the urine cultures were sterile in all cases
• CT revealed marked thickening of the bladder wall, a small capacity, and perivesicular stranding, consistent with severe inflammation; at cystoscopy, all patients had severe ulcerative cystitis.
• biopsies in 4 patients revealed epithelial denudation and inflammation with a mild eosinophilic infiltrate
• cessation of ketamine use, with the addition of pentosan polysulfate, appeared to provide some symptomatic relief

• the prevalence rates of self-reported IC and IC-like symptoms among controls in the community were 3.7% and 4.4%, respectively
 
OAB and IC/PBS Diagnosis of interstitial cystitis/ painful bladder syndrome in patients with overactive bladder symptoms.
Macdiarmid SA, Sand PK. Rev Urol 2007;9:9-16
• overactive bladder (OAB) and interstitial cystitis (IC) have similar symptoms, including urinary urgency/frequency and nocturia, making them difficult to differentiate on the basis of clinical presentation alone
• the authors propose a diagnostic framework that may be useful for differentiating IC from OAB and for facilitating appropriate treatment
 
bacteriuria

There is a low incidence of recurrent bacteriuria in painful bladder syndrome/interstitial cystitis patients followed longitudinally.
Stanford E, McMurphy C. Int Urogynecol J 2007;18:551-4
• this study suggests that the symptoms of flares of IC are not usually associated with recurrent urinary tract infections and, therefore, are likely due to a triggering of other painful mechanisms involved in IC patients who are culture-negative

 
bladder endometriosis

• the authors conclude that in terms of symptoms:
- IC and PBS may be the same entity; recurrent urinary tract infections may be distinguished from IC and PBS via a combination of self-report and urine culture information
- IC and PBS may be distinguished from OAB, vulvodynia and endometriosis, although identifying IC and PBS in women with more than 1 of these diseases may be difficult
