Therapeutic intervention for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS): a systematic review and meta-analysis.

BACKGROUND: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) has been treated with several different interventions with limited success. This meta-analysis aims to review all trials reporting on therapeutic intervention for CP/CPPS using the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI). METHODS: We searched Medline, PubMed, the Cochrane Pain, Palliative & Supportive Care Trials, the Cochrane Register of Controlled Trials, CINAHL, ClinicalTrials.gov, and the NIDDK website between 1947 and December 31, 2011 without language or study type restrictions. All RCTs for CP/CPPS lasting at least 6 weeks, with a minimum of 10 participants per arm, and using the NIH-CPSI score, the criterion standard for CP/CPPS, as an outcome measure were included. Data was extracted from each study by two independent reviewers. Gillbraith and I-squared plots were used for heterogeneity testing and Eggers and Peters methods for publication bias. Quality was assessed using a component approach and meta-regression was used to analyze sources of heterogeneity. RESULTS: Mepartricin, percutaneous tibial nerve stimulation (PTNS), and triple therapy comprised of doxazosin + ibuprofen + thiocolchicoside (DIT) resulted in clinically and statistically significant reduction in NIH-CPSI total score. The same agents and aerobic exercise resulted in clinically and statistically significant NIH-CPSI pain domain score reduction. Acupuncture, DIT, and PTNS were found to produce statistically and clinically significant reductions in the NIH-CPSI voiding domain. A statistically significant placebo effect was found for all outcomes and time analysis showed that efficacy of all treatments increased over time. Alpha-blockers, antibiotics, and combinations of the two failed to show statistically or clinically significant NIH-CPSI reductions. CONCLUSION: Results from this meta-analysis reflect our current inability to effectively manage CP/CPPS. Clinicians and researchers must consider placebo effect and treatment efficacy over time and design studies creatively so we can more fully elucidate the etiology and role of therapeutic intervention in CP/CPPS.

Chronic prostatitis.

INTRODUCTION: Chronic prostatitis can cause pain and urinary symptoms, and usually occurs without positive bacterial cultures from prostatic secretions (known as chronic abacterial prostatitis or chronic pelvic pain syndrome [CP/CPPS]). Bacterial infection can result from urinary tract instrumentation, but the cause and natural history of CP/CPPS are unknown. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for chronic bacterial prostatitis? What are the effects of treatments for chronic abacterial prostatitis/chronic pelvic pain syndrome? We searched: Medline, Embase, The Cochrane Library, and other important databases up to August 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS: We found 33 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS: In this systematic review, we present information relating to the effectiveness and safety of the following interventions: 5 alpha-reductase inhibitors, allopurinol, alpha-blockers, biofeedback, local injections of antimicrobial drugs, mepartricin, non-steroidal anti-inflammatory drugs (NSAIDs), oral antimicrobial drugs, pentosan polysulfate, prostatic massage, quercetin, radical prostatectomy, sitz baths, transurethral microwave thermotherapy, and transurethral resection.

Review of recent placebo-controlled trials utilizing phytotherapeutic agents for treatment of BPH.

BACKGROUND: In order to assess the efficacy of phytotherapeutic agents for the treatment of benign prostatic hyperplasia (BPH), a review of recently published double-blind placebo-controlled trials was undertaken. METHODS: Only those studies reviewed by the Other Medical Therapies Committee of the Fourth International Consultation on BPH were included. RESULTS: These studies suggest a possible benefit for the use of phytotherapeutic preparations in the treatment of BPH. CONCLUSIONS: These studies need to be confirmed in larger long-term placebo-controlled studies in order to ascertain the true efficacy of these agents.

[The role of mepartricin in the medical treatment of benign prostatic adenoma]. / Ruolo della mepartricina nella terapia medica dell'adenoma prostatico benigno.

A "cross over" study was carried out in a group of 22 subjects with prostatic hypertrophy in different stages, first treated with chloroformic extract of Pygeum Africanum (4 capsules/die for 30 days) and afterwards, when the symptoms reappeared, with mepartricin (3 gastroresistant tablets of 50,000 U. each/die for 30 days). Both substances proved to be active against the urinary symptomatology; however the polyene induced a significant decrease in the prostate size (evaluated by cystography), justifying the 77% of "excellent" results against the 13% obtained with the reference drug.
