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

ABSTRACT:

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.

Project description:IntroductionChronic pelvic pain syndrome (CPPS) is a complex disorder that affects a large proportion of all men. A limited understanding of its etiology and pathogenesis is reflected by the absence of effective therapies. Although CPPS is deemed clinically non-infectious with no well-defined etiological role for microbes, bacteria is readily isolated from both healthy and patient prostate secretion and urine samples. Our laboratory has previously demonstrated that a specific gram-negative bacterial isolate can induce CPPS-like symptoms in mice. Here we aimed to expand on these findings examining the role of gram-positive patient-derived bacteria in CPPS.MethodsA retrospective analysis of bacterial cultures from CPPS patients from a single center was performed. Gram-positive bacteria were isolated from the expressed prostatic secretion (EPS) of three CPPS-patients (pain inducers, PI) and one from a healthy volunteer (non-pain inducer, NPI). These bacteria were inoculated intra-urethrally in two mouse backgrounds and analyzed for their ability to induce tactile allodynia, voiding dysfunction, and colonize the murine prostate. Host immune responses to bacterial instillation were analyzed by flow cytometry.ResultsPI strains (Staphylococcus haemolyticus 2551, Enterococcus faecalis 427, and Staphylococcus epidermidis 7244) induced and maintained tactile allodynia responses (200% increase above baseline) for 28 days in NOD/ShiLtJ mice. Conversely the healthy subject derived strain (Staphylococcus epidermidis NPI) demonstrated no significant pelvic allodynia induction. Intra-urethral inoculation of the four bacterial strains into C57BL/6 mice did not induce significant increases in pain responses. Infected NOD/ShiLtJ displayed significant voiding dysfunction compared to their control counterparts. Colony counts of prostate tissues from both NOD/ShiLtJ and C57BL/6 mice at day 28 demonstrated that bacterial strains colonized equally well, including NPI. We also determined that mechanistically, the patient-isolates induced prostate inflammation specifically involving T-cells and monocytes.ConclusionsGram-positive isolates from CPPS patients showed enhanced ability to induce tactile allodynia compared to a single taxonomically similar gram-positive strain isolated from a healthy control. Responses were shown to be dependent on host genetic background and not on colonization differences between strains.

Project description:Acupuncture is a promising therapy for relieving symptoms in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), which affects >15% of adult men worldwide. The aim of the study was to assess the effects and safety of the use of acupuncture for CP/CPPS. MEDLINE, EMBASE, CENTRAL, Web of Science, CBM, CNKI, Wang-Fang Database, JCRM, and CiNii were searched from their inception through 30 November 2015. Grey literature databases and websites were also searched. No language limits were applied. Only randomized controlled trials (RCTs) with CP/CPPS treated by acupuncture were included. Two reviewers extracted data and assessed the risk of bias of RCTs using the Cochrane Risk of Bias Tools, respectively. Seven trials were included, involving 471 participants. The result of meta-analysis indicated that compared with sham acupuncture (MD: -6.09 [95%CI: -8.12 to -5.68]) and medicine (Levofloxacinand, Ibuprofen, and Tamsulosin) (MD: -4.57 [95%CI: -7.58 to -1.56]), acupuncture was more effective at decreasing the total NIH-CPSI score. Real acupuncture was superior to sham acupuncture in improving symptoms (pain, voiding) and quality of life (Qof) domain subscores. Compared to sham acupuncture and medicine, acupuncture appears to be more effective at improving the global assessment. Two trials found that there is no significant difference between acupuncture and sham acupuncture in decreasing the IPSS score. Acupuncture failed to show more favorable effects in improving both symptoms and the Qof domain compared with medicine. Overall, current evidence supports acupuncture as an effective treatment for CP/CPPS-induced symptoms, particularly in relieving pain. Based on the meta-analysis, acupuncture is superior to sham acupuncture in improving symptoms and Qof. Acupuncture might be similar to medicine (Levofloxacinand, Ibuprofen, and Tamsulosin) in its long-term effects, but evidence was limited due to high ROB among included trials as well as potential heterogeneity. Acupuncture is associated with rare and slightly adverse events. Protocol registration PROSPERO CRD42015027522.

Project description:ContextAcupuncture is a promising therapy for relieving symptoms in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), which affects 9-16% of adult men worldwide.ObjectiveThis study aims to explore the efficacy and safety of acupuncture for CP/CPPS.Evidence acquisitionNine electronic databases were searched. Only randomized controlled trials were included. Two reviewers extracted data and assessed the risk of bias of trials using the revised Cochrane risk-of-bias (RoB 2.0) tool. Stata 17.0 was used to analyze the data.Evidence synthesisTwelve trials were included. The results of a meta-analysis showed that acupuncture had larger effect sizes (standardized mean difference [SMD] = -1.20, confidence interval or CI [-1.69, -0.71], acupuncture compared with sham acupuncture; SMD = -1.01, CI [-1.63, -0.38], acupuncture compared with medication; SMD = -0.91, CI [-1.29, -0.54], acupuncture plus medication compared with medication) in reducing the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score. In decreasing NIH-CPSI pain domain score, acupuncture also led to larger effect sizes (SMD = -0.94, CI [-1.18, -0.70], acupuncture compared with sham acupuncture; SMD = -1.04, CI [-1.29, -0.79], acupuncture compared with medication; SMD = -0.85, CI [-1.23, -0.48], acupuncture plus medication compared with medication), whereas the effect sizes in the reduction of NIH-CPSI urinary domain and quality of life domain scores were medium. Compared with sham acupuncture and medication, acupuncture appears to be more effective in improving the global response rate. Results from four trials indicated that acupuncture was better than sham acupuncture in decreasing the International Prostate Symptom Score. No serious adverse effects were found in the acupuncture treatment.ConclusionsCurrent evidence supports acupuncture as an effective treatment for CP/CPPS-induced symptoms, particularly in relieving pain. Comprehensive acupuncture treatment according to individual symptoms should be considered in future clinical practice and trials for CP/CPPS.Patient summaryIn this study, we further verified the efficacy of acupuncture in patients with chronic prostatitis/chronic pelvic pain syndrome, especially in reducing pain.
