chondroitin-sulfates and Nocturia

To assess the efficacy of intravesical hyaluronic acid (HA) and HA/chondroitin sulfate (CS) instillation in patients with interstitial cystitis/painful bladder syndrome by systematic review and meta-analysis.. A systematic literature search was performed using the keywords: 'interstitial cystitis' or 'painful bladder syndrome' or 'bladder pain syndrome' and 'hyaluronic acid', up to March 31, 2016. The primary outcome was visual analogue scale related pain symptom (VAS). Secondary outcomes were the O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI) and Problem Index (ICPI), frequency, nocturia, bladder volume, and voided urine volume.. Ten articles involving 390 patients were retrieved and assessed in analysis. A significant improvement in mean VAS on fixed-effect and random-effect models (mean difference [MD] -3.654, 95% confidence interval [CI] -3.814 to -3.495, and MD -3.206, 95% CI -4.156 to -2.257, respectively) was found. Significant improvements were found in the ICSI (MD -3.223, 95% CI -4.132 to -2.315) and ICPI (MD -2.941, 95% CI -3.767 to -2.116). Similarly, the other outcomes were significantly improved.. Intravesical HA and HA/CS instillation improved pain symptom, quality of life, and other outcomes and could be included as therapeutic modality of interstitial cystitis/painful bladder syndrome.

Intravesical glucosaminoglycan (GAG) replacement therapies are commonly used in the treatment of bladder pain syndrome (BPS)/interstitial cystitis (IC). Different intravesical glucosaminoglycan products are currently available. In this prospective study, clinical efficacy of chondroitin sulfate and hyaluronic acid are compared in patients with BPS/IC.. Patients were randomized to CS and HA groups. All patients were evaluated for visual analogue pain scale (VAS), interstitial cystitis symptom index (ICSI), interstitial cystitis problem index (ICPI), voiding diary for frequency/nocturia, and mean urine volume per void at the beginning of the therapy and after 6 months. All patients had a potassium sensitivity test (PST) initially. Wilcoxon and Mann-Whitney U tests were used for statistical analysis.. There were 21 patients in both groups. Mean age of patients in CS and HA groups were 47.10 and 48.90, respectively(P > 0.05). Before treatment, Parson's test was positive in 64.3% of patients (27/42) with no difference between groups. VAS of pain, ICSI, ICPI, frequency at 24 h and nocturia results have improved significantly at both treatment arms. Intravesical CS was also found superior to intravesical HA in terms of 24 h frequency, nocturia and ICPI (P < 0.05). No severe adverse effects were reported.. Data comparing clinical efficiencies of different GAG therapies are very limited. In this study, intravesical CS was found superior to intravesical HA in terms of 24 h frequency, nocturia and ICPI in patients with BPS/IC in short term follow-up. To provide a definitive conclusion on superiority of one GAG therapy to others, further evaluation with long term follow up is required.

Radiotherapy is one of the treatment options for prostate cancer (PCa) but up to 25% of men report about severe nocturia (nocturnal voiding). The combination of hyaluronic acid (HA) and chondroitin sulfate (CS) resembles glycosaminoglycan (GAG) replenishment therapy. The aim of our study was to evaluate the impact of HA and CS on nocturia, in men with nocturia after PCa radiotherapy.. Twenty-three consecutive patients with symptomatic cystitis after external radiotherapy for PCa were enrolled. Patients underwent bladder instillation therapy with HA and CS weekly for the first month and, afterwards, on week 6, 8 and 12. Nocturnal voiding frequency was assessed by item 3 (Q3) of the Interstitial Cystitis Symptoms Index (ICSI) and item 2 (Q2) of the Interstitial Cystitis Problem Index (ICPI). Data were analyzed with paired-samples T-test and adjusted for age.. Eighteen patients (78%) reported about nocturia. Pre- and post-treatment ICSI-Q3 was 2.13 ± 0.28 and 1.61 ± 0.21 (-24.4%, p = 0.001). With logistic regression analysis, both age and baseline ICSI-Q3 had a significant impact on nocturnal voiding frequency (r = 0.293, p = 0.011 and r = 0.970, p < 0.001). Pre- and post-treatment ICPI-Q2 was 1.87 ± 0.26 and 1.30 ± 0.25 (-30.5%, p = 0.016); logistic regression analysis was without significant findings.. Bladder instillation treatment with a combination of HA and CS was effective in reducing nocturnal voiding frequency in men with post-radiation bladder pain for PCa. Randomized, controlled trials with sham treatment are needed to confirm our result.
