Network Meta-Analysis of the Efficacy of Acupuncture, Alpha-blockers and Antibiotics on Chronic Prostatitis/Chronic Pelvic Pain Syndrome

The Tandem of Liquid Chromatography and Network Pharmacology for the Chemical Profiling of Pule'an Tablets and the Prediction of Mechanism of Action in Treating Prostatitis

Prostatitis, a prevalent urinary tract disorder in males, has a complex etiology that leads to severe clinical discomfort. Pule'an Tablets, a classic single-component formulation primarily based on rapeseed pollen, have been clinically proven to have a beneficial therapeutic effect on both prostatitis and benign prostatic hyperplasia. However, there is currently a lack of research on the chemical composition and mechanisms of action of Pule'an Tablets in treating prostatitis. In this study, using liquid chromatography-mass spectrometry (LC-MS), a total of 53 compounds in Pule'an Tablets were identified, including flavonoids, phenylpropionamides, lipids, glucosinolates, and nucleic acids. Subsequently, through a network pharmacology analysis, potential target genes and their mechanisms of action were predicted accordingly. The results suggested that genes such as LPAR5, LPAR6, LPAR4, LPAR3, LPAR2, LPAR1, F2, ENPP2, MMP9, and TNF, along with pathways like prostate cancer, endocrine resistance, bladder cancer, and the IL-17 signaling pathway, may represent potential pathways involved in the therapeutic effects of Pule'an Tablets. This study represents the first systematic investigation into the chemical composition of Pule'an Tablets, shedding light on the potential mechanisms underlying their efficacy in treating prostatitis. These findings could serve as a valuable reference for future pharmacological research on Pule'an Tablets.

Biopsychosocial approach to male chronic pelvic pain syndrome: recent treatments and trials

INTRODUCTION

Chronic pelvic pain syndrome (CPPS) is a common urologic condition that can cause significant disability in affected individuals. Physiologic explanations of chronic pain are often incomplete; appropriate management of CPPS includes recognition of biological, psychological, and social elements, known as the biopsychosocial model.

OBJECTIVE

The aim of this narrative review is to investigate treatments for men with CPPS, with a special focus on those utilizing the biopsychosocial model of care.

METHODS

A comprehensive literature search was conducted on the electronic databases PubMed, Embase, and Cochrane Library, using relevant Medical Subject Heading terms and keywords related to CPPS treatments. The search was limited to studies published in English from inception to January 2023. Additionally, reference lists of selected studies were manually reviewed to find studies not identified by the initial search. Studies were included if they investigated pharmacologic or nonpharmacologic treatments for men with CPPS.

RESULTS

A total of 30 studies met the inclusion criteria. Antibiotics, α-blockers, nonsteroidal anti-inflammatory drugs, gabapentinoids, antidepressants, and phosphodiesterase type 5 inhibitors were among the pharmacologic agents included in trials attempting to reduce symptoms of male CPPS. Studies that focused on treating CPPS without medication included interventions such as shockwave therapy, acupuncture, physical therapy, botulinum toxin, cryotherapy, electrotherapy, exercise, and cognitive behavioral therapy.

CONCLUSION

α-Blockers and nonsteroidal anti-inflammatory drugs have shown promising results in treating CPPS in men, while the effectiveness of antibiotics remains controversial. Antidepressants and phosphodiesterase type 5 inhibitors may also be useful in decreasing symptoms in patients with CPPS. Treatments such as pelvic floor muscle therapy, acupuncture, shockwave therapy, and cognitive behavioral therapy must be considered effective complements to medical management in men with CPPS. While these interventions demonstrate benefits as monotherapies, the individualization and combination of treatment modalities are likely to result in reduced pain and improved quality of life.

Research Trends of Acupuncture Therapy on Chronic Pelvic Pain Syndrome from 2000 to 2022: A Bibliometric Analysis

Background

Acupuncture is considered an important means of analgesic, which has been widely used in chronic pelvic pain syndrome (CPPS) management and treatment in recent years, published a large number of related documents. However, the relevant literature in this field has not been summarized and quantitatively analyzed. Therefore, this study aims to analyze the hotspots and predicting future research trends of acupuncture on pelvic pain syndrome.

Methods

Search for the relevant publications of the web of science database from 2000 to 2022 about the treatment of acupuncture on chronic pelvic pain syndrome. The Citespace software and VosViewer software are used to analyze the visualization of the countries, institutions, authors, keywords and references and references in the literature.

Results

A total of 173 publications were included. The annual number of essays gradually showed an overall growth trend over time. Medicine magazine is the most published journal in this field. J UROLOGY and Acupunct Med are the most cited journals and the most influential magazines; The most active and influential country is China, and the most produced institutions are Beijing University of Chinese Medicine; The most produced authors are Liu Zhishun. The most cited and most influential authors are Nickel JC and Armour M; keywords and cited reference analysis show that the quality of life, mechanism research, alternative medicine and electro-acupuncture will be the scientific hotspot of acupuncture treatment for chronic pelvic pain syndrome.

Conclusion

This study shows that acupuncture on CPPS is increasingly valued and recognized. The future research hotspots will focus on the effects and mechanisms. In the future, more high-quality animal basic research will be required to explore the exact mechanism of acupuncture on CPPS. In addition, different parameters of acupuncture such as electric-acupuncture, stimulating frequency, duration and strength are also the focus of future research. More clinical trials are required to verify its safety and effectiveness.

The methodological quality assessment of systematic reviews/meta-analyses of chronic prostatitis/chronic pelvic pain syndrome using AMSTAR2

BACKGROUND

This study aimed to assess the methodological quality of the systematic reviews/meta-analyses (SRs/MAs) of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) using A Measurement Tool to Assess systematic Reviews (AMSTAR2) and to explore the potential influencing factors.

METHODS

PubMed, EMBASE and Cochrane Library databases were searched for relevant studies. AMSTAR2 was used for evaluating the methodological quality of eligible SRs/MAs. Differences between methodological characteristics of SRs/MAs were compared using chi-square tests. The intra-class correlation coefficient (ICC) was used to assess reviewer agreement in the pre-experiment. Multivariate regression analysis was used to identify potential factors affecting methodological quality.

RESULTS

A total of 45 SRs/MAs were included. After AMSTAR2 evaluation, only two (4.4%) of 45 SRs/MAs were moderate, three (6.7%) were rated as low quality, and the remainder 40 (88.9%) were rated as critically low quality. Among the 16 items of AMSTAR2, item 3 and item 10 had the poorest adherence. Item 4 received the most significant number of "Partial Yes" responses. Univariable analysis indicated that there were significant differences in methodological quality in SRs between different continents (P = 0.027) as well as between preregistered SRs and those that were not (P = 0.004). However, in multivariate analysis, there was no significant association between methodological quality and the following research characteristics: publication year, continent, whether reporting followed Preferred Reporting Items for Systematic Reviews (PRISMA), preregistration, funding support, randomized controlled trials (RCT) enrollment, whether SR was published in the Cochrane Database of Systematic Reviews (CDSR), and whether with meta-analysis. Additionally, subgroup analysis based on interventional SRs/MAs showed that continent was independently associated with the methodological quality of SRs/MAs of CP/CPPS via univariable and multivariate analysis.

CONCLUSIONS

Our study demonstrates that the methodological quality of SRs/MAs of CP/CPPS was generally poor. SRs/MAs of CP/CPPS should adopt the AMSTAR2 to enhance their methodological quality.

Effect of electroacupuncture on cyclic adenosine monophosphate-protein kinase A-vanillic acid receptor subtype 1 of the transient receptor potential/PLK-protein kinase C-vanillic acid receptor subtype 1 of the transient receptor potential pathway based on RNA-seq analysis in prostate tissue in rats with chronic prostatitis/chronic pelvic pain syndrome

Objective

To investigate the analgesic mechanism of electroacupuncture (EA) in rats with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

Methods

Thirty male SD rats were randomly divided into sham group, model group and EA group, with ten rats in each group. The CP/CPPS model was prepared by injecting 50 μL of complete Freund's adjuvant (CFA) into the ventral lobes of the prostate tissue, and the sham group was injected with the same dose of saline. After 14 days of modeling, EA was applied to Guanyuan (CV4), Zhongji (CV3), Sanyinjiao (SP6) and Huiyang (BL35) in the EA group. After four courses, H&E staining was performed to observe the prostate tissue morphology, transcriptome sequencing (RNA-Seq) was performed for each group, and the selected signaling pathways were verified by qRT-PCR.

Results

The RNA-Seq analysis results suggested that the analgesic effect of EA on CP/CPPS may be achieved by regulating prostate gene expression, which may be related to multiple biological processes and signaling pathways. qRT-PCR results showed that the vanillic acid receptor subtype 1 of the transient receptor potential (TRPV1), phospholipase C (PLC), protein kinase C (PKC), cyclic adenosine monophosphate (cAMP), and protein kinase A (PKA) were all upregulated in the model group compared to the sham group (p < 0.01). Compared with the model group, TRPV1, PLC, PKC, cAMP, and PKA were all downregulated in the EA group (p < 0.05, p < 0.01).

Conclusion

The analgesic mechanism of EA on CP/CPPS may be achieved through modulation of cAMP-PKA-TRPV1/PLC-PKC-TRPV1 signaling pathway.

Therapeutic interventions to urologic chronic pelvic pain syndrome and UPOINT system for clinical phenotyping: How far are we?

The assessment and management of urologic chronic pelvic pain syndrome (UCPPS), is controversial. It is classified by voiding symptoms, pelvic pain, and bladder pain, which is weekly treated, weekly understood, and bothersome. In the aspect of clinical efforts and research to help people with this syndrome have been hampered by the deficiency of a widely reliable, accepted, and a valuable tool to evaluate the patient symptoms and quality of life (QoL) impact. However, the etiology comes into sight is multifactorial, and available treatment options have been imprecise considerably in present years. We compiled the published literature on the assessment of the syndrome, a tentative role of pharmacological and non-pharmacological (conservative, alternative, and invasive therapy) interventions in eradicating the disease as well as improving symptoms. The previously published literature on animal models has established the association of immune systems in the etiology, pathogenesis, and progression of the disease. The UPOINT system for clinical phenotyping of UCPPS patients has six predefined domains that direct multimodal therapy, which would lead to significant symptom improvement in the medical field. The narrative review aims to scrutinize the fluctuating scientist's views on the evaluation of patient and multimodal treatment of the UPOINT system.

The Efficacy and Safety of Extracorporeal Shockwave Therapy versus Acupuncture in the Management of Chronic Prostatitis/Chronic Pelvic Pain Syndrome: Evidence Based on a Network Meta-analysis

The aim of this study was to evaluate the efficacy and safety of extracorporeal shockwave therapy (ESWT) and acupuncture therapy for patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

We searched electronic databases including PubMed, Cochrane Library, Embase and web of science from its inception to June 1, 2021. The randomized controlled trials (RCTs) that compared ESWT and acupuncture in the management of CP/CPPS were identified. A network meta-analysis was conducted with the software of STATA 14.0.

Nine RCTs with 525 patients were enrolled in our analysis. The results revealed that both ESWT and acupuncture were significantly better than the sham procedure in the outcomes of total score of NIH-CPSI, pain subscore, urinary symptoms subscore, QoL subscore, IPSS score, the IIEF score and response rates (p < .05). Both ESWT and acupuncture were well-tolerated and had no obviously increased adverse events. Compared with acupuncture, ESWT was associated with better short term (<4w) and mid-term (8-12 w) efficacy of total score, pain subscore, urinary symptoms subscore, and QoL subscore of NIH-CPSI, IPSS score, IIEF score, and response rate. However, ESWT did not present better long-term (<24 w) outcomes than acupuncture in total score, pain subscore, urinary symptoms subscore, and QoL subscore of NIH-CPSI.

Both ESWT and acupuncture were effective and well-tolerated in the management of CP/CPPS. ESWT seemed to have better short (<4 w) and mid-term (8-12 w) efficacy but similar long-term (>24 w) efficacy than acupuncture.

Role of Neuroimmune Crosstalk in Mediating the Anti-inflammatory and Analgesic Effects of Acupuncture on Inflammatory Pain

Inflammatory pain is caused by peripheral tissue injury and inflammation. Inflammation leads to peripheral sensitization, which may further cause central sensitization, resulting in chronic pain and progressive functional disability. Neuroimmune crosstalk plays an essential role in the development and maintenance of inflammatory pain. Studies in recent years have shown that acupuncture can exert anti-inflammatory and analgesic effects by regulating peripheral (i.e., involving local acupoints and inflamed regions) and central neuroimmune interactions. At the local acupoints, acupuncture can activate the TRPV1 and TRPV2 channels of mast cells, thereby promoting degranulation and the release of histamine, adenosine, and other immune mediators, which interact with receptors on nerve endings and initiate neuroimmune regulation. At sites of inflammation, acupuncture enables the recruitment of immune cells, causing the release of opioid peptides, while also exerting direct analgesic effects via nerve endings. Furthermore, acupuncture promotes the balance of immune cells and regulates the release of inflammatory factors, thereby reducing the stimulation of nociceptive receptors in peripheral organs. Acupuncture also alleviates peripheral neurogenic inflammation by inhibiting the release of substance P (SP) and calcitonin gene-related peptide from the dorsal root ganglia. At the central nervous system level, acupuncture inhibits the crosstalk between glial cells and neurons by inhibiting the p38 MAPK, ERK, and JNK signaling pathways and regulating the release of inflammatory mediators. It also reduces the excitability of the pain pathway by reducing the release of excitatory neurotransmitters and promoting the release of inhibitory neurotransmitters from neurons and glial cells. In conclusion, the regulation of neuroimmune crosstalk at the peripheral and central levels mediates the anti-inflammatory and analgesic effects of acupuncture on inflammatory pain in an integrated manner. These findings provide novel insights enabling the clinical application of acupuncture in the treatment of inflammatory diseases.

Comparative Efficacy of Oral Chinese Patent Medicine for Chronic Prostatitis/Chronic Pelvic Pain Syndrome With Sexual Dysfunction: A Bayesian Network Meta-Analysis of Randomized Controlled Trials

Background: Oral Chinese patent medicine (OCPM) combined with western medicine (WM) are believed to be effective for the therapy of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) with sexual dysfunction (SD). These western medicines mainly involve antibiotics, phosphodiesterase type-5 inhibitor (PDE-5i), α-blockers. But there is no randomized controlled trial (RCT) that directly compares the efficacy of different OCPM. Hence, we operated a network meta-analysis (NMA) to contrast the efficacy of different OCPM for CP/CPPS with SD.

Methods: Relevant studies were searched in PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), and Wanfang database. All of the RCTs concentrated on the use of OCPM to cure CP/CPPS with SD from the inception of the databases to November 2020. We appraised the risk of bias under the Cochrane Handbook and CONSORT statement. The data were statistically analyzed via STATA 13.0 and WinBUGS 1.4.3 instrument.

Results: Altogether, 30 pieces of literature with 2,996 participants containing 11 oral Chinese patent medicine and 11 interventions were included in the NMA. In terms of The National Institutes of Health chronic prostatitis symptom index (NIH-CPSI), Qianlie Shutong Capsules (QLSTC) + WM had the most possible of being the optimal treatment. In the light of the International Index of Erectile Function (IIEF-5), Congrong Yishen Granules (CRYSG) + WM had the most possible of being the optimal treatment. Shugan Yiyang Capsules (SGYYC) + WM performed the highest likelihood efficacy under cluster rank graph combined NIH-CPSI and IIEF-5. Liuwei Dihuang Pills/Yougui capsules (LWDHP/YGC) + WM had highly possible to be the optimal treatment not only for the clinical effective rate of CP/CPPS but also for the clinical effective rate of SD. Considering four outcomes, QLSTC, CRYSG, SGYYC, LWDHP/YGC, Qianlie Beixi Capsules (QLBXC) plus WM were the best therapy approach for CP/CPPS with SD, especially LWDHP/YGC + WM and QLBXC + WM.

Conclusion: Based on the NMA, QLSTC, CRYSG, SGYYC, LWDHP/YGC, QLBXC plus WM demonstrated the maximum probability of being the optimal therapies. Owing to the limitations of this research, these results should be confirmed by elaborate RCTs.

EVIDENCE ACQUISITION

Narrative review.

RESULTS

Chronic pelvic pain can be a complex disorder that may involve multiple systems such as urogynecological, gastrointestinal, neuromusculoskeletal, and psychosocial systems. The etiopathogenesis for chronic pain remains unknown for many patients. For achieving optimal patient management, a multimodal and individualized assessment of each patient is the best strategy.

CONCLUSIONS

There are non-pharmacologic treatments as well as pharmacologic treatments. In addition to these treatment options, inferior hypogastric plexus block is a promising treatment modality.

The Quality of Methodological and Reporting in Network Meta-Analysis of Acupuncture and Moxibustion: A Cross-Sectional Survey

Background

Acupuncture had long been a primary treatment in the healthcare system of China. In recent years, there were more and more network meta-analyses (NMAs) in the field of acupuncture and moxibustion, but the quality evaluation of NMAs was rare.

Objectives

The goal of this study was to evaluate the methodological and reporting quality of NMAs and summarize the effects of different treatments of acupuncture and moxibustion.

Methods

PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure Database (CNKI), WanFang Database (WF), Chinese Scientific Journal Database (VIP), and Chinese Biomedical Literature Database (CBM) were searched from inception to January 2020 without any language restriction. In addition, the unpublished studies and the references of initially included literature were also retrieved manually. We included all relevant NMAs treated with acupuncture and moxibustion; other therapies such as traditional Chinese medicine and Western medicine may also be included, but at least three types fall under the category of acupuncture in each NMA. Outcome indicators were not limited. We selected AMSTAR2 and PRISMA-NMA to evaluate the methodological and reporting quality of eligible studies, respectively.

Results

In total, 29 NMAs were included finally, including 12 Chinese references and 17 English references. All eligible studies were published from May 2013 to August 2019. The number of interventions was between 4 and 22. The number of clinical trials included ranged from 10 to 121, with a total of 1098 clinical trials. The NMAs were involved in up to 23 diseases, knee osteoarthritis and primary dysmenorrhea covered with 3 NMAs separately, others focusing on chronic functional constipation, lumbar disc herniation, chronic fatigue syndrome, and the like. The Jadad scale and RoB scale were used as the bias risk assessment tools. Among them, 7 articles adopted the Jadad scale, 22 articles adopted the RoB scale (1 article adopted both the Jadad scale and RoB scale), and only 1 article did not mention the risk assessment tool. The AMSTAR2 methodological evaluation showed that the highest score was 13.5 points and the lowest was 4, with an average of 8.64 and a median of 9.5. According to the quality criteria, only one of them was in high quality, twenty-four were in medium quality, and four were in low quality. The PRISMA-NMA reporting quality evaluation showed that the highest score was 29 points and the lowest was 13.5, with an average of 23.62 and a median of 24.5; severe flaws also existed in some items, especially in "Structured summary," "Protocol and registration," "Search," "Data collection process," "Data items," "Additional analyses," "Risk of bias across studies," and "Results of additional analyses."

Conclusion

The number of NMAs in the field of acupuncture and moxibustion was still in the initial stage. Overall, their methodology and reports were of moderate quality. However, severe flaws also existed in some items. Because the eligible NMAs were limited, the conclusion needed further research to confirm its authenticity and reliability.

Optimal acupoint and session of acupuncture for patients with chronic prostatitis/chronic pelvic pain syndrome: a meta-analysis

Background

The study aims to perform a meta-analysis of published trials and evaluate the efficacy of acupuncture on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) by symptom score reduction, optimal acupuncture session, and most frequently used acupoints.

Methods

A literature search was performed for randomized controlled trials (RCTs) comparing efficacy of acupuncture with sham acupuncture or standard medication on CP/CPPS. The primary outcome was the reduction of National Institute of Health-Chronic Prostatitis Index (NIH-CPSI) total score and its subscales. The optimal acupuncture session to reach its clinical efficacy and most common compatibility rule of acupoints were also evaluated.

Results

Ten trials involving 770 participants were included. Meta-analysis showed compared with sham acupuncture, acupuncture yielded significant reduction in NIH-CPSI total score [weighted mean difference (WMD): 7.28, 95% confidence interval (95% CI): 5.69-8.86), and provided better pain relief (WMD: 3.57, 95% CI: 2.07-5.08), urinary symptoms improvement (WMD: 1.68, 95% CI: 1.13-2.22), and quality of life (QOL) (WMD: 2.38, 95% CI: 1.41-3.36). Compared with standard medication, acupuncture were more efficacious in reducing NIH-CPSI total score (WMD: 3.36, 95% CI: 1.27-5.45), also showed significant greater pain relief (WMD: 2.36, 95% CI: 1.67-3.06), marginal advantage in improving QOL (WMD: 0.98, 95% CI: 0.12-1.83) but no difference in reducing urinary symptom (WMD: -0.03, 95% CI: -1.30 to 1.24). Four acupuncture sessions were the minimum "dose" to reach clinical efficacy, and prolonged acupuncture sessions continuously improved urinary symptoms and QOL. The majority of acupoint selection strategies were based on the combination of any three acupoints from CV3, CV4, BL32, SP6, and SP9.

Conclusions

Acupuncture has promising efficacy for patients with CP/CPPS, especially category IIIB, in aspects of relieving pain and urinary symptoms and improving the QOL. Acupuncture may serve as a standard treatment option when available, and a tailored comprehensive treatment strategy for CP/CPPS is the future trend.

A scoping review of network meta-analyses assessing the efficacy and safety of complementary and alternative medicine interventions

BACKGROUND

Network meta-analysis (NMA) has rapidly grown in use during the past decade for the comparison of healthcare interventions. While its general use in the comparison of conventional medicines has been studied previously, to our awareness, its use to assess complementary and alternative medicines (CAM) has not been studied. A scoping review of the literature was performed to identify systematic reviews incorporating NMAs involving one or more CAM interventions.

METHODS

An information specialist executed a multi-database search (e.g., MEDLINE, Embase, Cochrane), and two reviewers performed study selection and data collection. Information on publication characteristics, diseases studied, interventions compared, reporting transparency, outcomes assessed, and other parameters were extracted from each review.

RESULTS

A total of 89 SR/NMAs were included. The largest number of NMAs was conducted in China (39.3%), followed by the United Kingdom (12.4%) and the United States (9.0%). Reviews were published between 2010 and 2018, with the majority published between 2015 and 2018. More than 90 different CAM therapies appeared at least once, and the median number per NMA was 2 (IQR 1-4); 20.2% of reviews consisted of only CAM therapies. Dietary supplements (51.1%) and vitamins and minerals (42.2%) were the most commonly studied therapies, followed by electrical stimulation (31.1%), herbal medicines (24.4%), and acupuncture and related treatments (22.2%). A diverse set of conditions was identified, the most common being various forms of cancer (11.1%), osteoarthritis of the hip/knee (7.8%), and depression (5.9%). Most reviews adequately addressed a majority of the PRISMA NMA extension items; however, there were limitations in indication of an existing review protocol, exploration of network geometry, and exploration of risk of bias across studies, such as publication bias.

CONCLUSION

The use of NMA to assess the effectiveness of CAM interventions is growing rapidly. Efforts to identify priority topics for future CAM-related NMAs and to enhance methods for CAM comparisons with conventional medicine are needed.

Beneficial effect of tamsulosin combined with dapoxetine in management of type III prostatitis with premature ejaculation

To evaluate the efficacy and safety of tamsulosin combined with dapoxetine in the treatment of type IIIB chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) that is complicated by premature ejaculation (PE), a total of 251 CP/CPPS patients with PE were recruited from nine hospitals across China and were randomly divided into two groups: one received tamsulosin as a control, and the other received a combination therapy of tamsulosin and dapoxetine. Follow-up was conducted at four time points, and indicators describing CP/CPPS and PE were compared between the two groups. In all, 223 patients were followed up at least once, and 114 patients completed all of the treatment process. The combination group showed more improvement in the symptoms of both PE and CP/CPPS, including thrust number (50.5 vs. 45), premature ejaculation profile score (11.39 vs. 6.96), intravaginal ejaculation latency time (5.95 min vs. 2.63 min) and the National Institutes of Health Chronic Prostatitis Symptom Index (7.44 vs. 11.81) in comparison with the tamsulosin group. In conclusion, for CP/CPPS patients with PE, tamsulosin combined with dapoxetine provided better therapeutic efficacy in the treatment of not only PE symptoms but also CP/CPPS indicators in comparison with tamsulosin monotherapy.

Using meta-regression approach to explore the dose-response association between acupuncture sessions and acupuncture effects on chronic prostatitis/chronic pelvic pain syndrome

Background

The benefits of acupuncture on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) have been well established according to previous studies. However, uncertainty exists regarding the dose-response relationship between acupuncture sessions and acupuncture effects for CP/CPPS. The objective of this study is to explore the association between the acupuncture sessions and its effects based on previously published data.

Methods

A non-linear meta-regression approach with restricted cubic spline (RCS) was used to investigate the dose-response relationship between acupuncture sessions and its effects on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI). PubMed, EMBASE, and Cochrane CENTRAL were searched up to May 20, 2018. Randomized controlled trials (RCTs) and case series studies (CSSs) reported the treatment sessions of acupuncture for CP/CPPS with at least two categories were eligible for inclusion.

Results

Ten studies involving 329 participants were included, the results showed a J-shaped dose-response association between acupuncture sessions and NIH-CPSI score (range 0 to 43, with higher score indicating greater CP/CPPS symptoms). Overall, more acupuncture sessions received for CP/CPPS patients is associated with increased symptom relieving. After 6 acupuncture sessions, the NIH-CPSI decreased from 26.1 (95% CI: 25.3-27.0) to 18.5 (95% CI: 11.6-25.4), with a between-session difference of -7.6 (95% CI: -14.6 to -0.7). Considering the 95%CI, both robust-error meta-regression modeling [MD: -8.3 (95% CI: -10.4 to -6.3)] and sensitivity analysis without CSSs [MD: -8.1 (95% CI: -9.5 to -6.7)] demonstrated that 18 acupuncture sessions could reach a clinically meaningful improvement regarding NIH-CPSI score.

Conclusions

There appear to be dose-response relationship between acupuncture sessions and CP/CPPS outcome. Prolonged acupuncture sessions were associated with less NIH-CPSI score. According to current evidence, six acupuncture sessions might be the minimal required 'dose' to reach its clinical effects.

Long-term effects of acupuncture for chronic prostatitis/chronic pelvic pain syndrome: systematic review and single-arm meta-analyses

BACKGROUND

Cumulative evidences indicate that acupuncture may ameliorate the symptoms of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). However, the long-lasting effects of acupuncture on CP/CPPS has not been fully evaluated. The objective of this study is to assess the sustained effects of acupuncture on CP/CPPS.

METHODS

We searched PubMed, EMBASE, and CENTRAL databases for studies on the use of acupuncture in patients with CP/CPPS. Studies with long-term follow-up periods were included. Single-arm meta-analyses were performed using random-effects model. The primary outcome was the response rate at the end of follow-up period; the secondary outcomes were changes of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) scores at the end of follow-up, including total score and 3 sub-scores (pain, urinary, and quality of life).

RESULTS

Six studies with 310 patients were performed in data synthesis, among which four studies were randomized controlled trials (RCT) and two were case series studies. At the end of follow-up, the weighted "average" response rate was 68.4% (95% CI: 42.1% to 89.5%, n=226; I2=93.5%); the change of NIH-CPSI total score were -14.8 (95% CI: -17.0 to -12.6, n=310; I2=92.1%); the change of pain, urinary, and quality of life sub-scores were -6.0 (95% CI: -6.9 to -5.2, n=266; I2=83.6%), -2.6 (95% CI: -3.2 to -2.0, n=266; I2=87.9%), and -4.4 (95% CI: -6.2 to -2.6, n=266; I2=98.7%), respectively. The source of heterogeneity could not be identified owing to insufficient studies.

CONCLUSIONS

Acupuncture may have clinically long-lasting benefits for CP/CPPS. However, current evidence is limited owing to insufficient data and significant heterogeneity. Further studies with larger sample size and long-term follow-up periods are warranted.

Non-pharmacological interventions for treating chronic prostatitis/chronic pelvic pain syndrome: a Cochrane systematic review

OBJECTIVE

To assess the effects of non-pharmacological therapies for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

PATIENTS AND METHODS

We performed a comprehensive search using multiple databases, trial registries, grey literature and conference proceedings with no restrictions on the language of publication or publication status. The date of the latest search of all databases was August 2017. We included randomized controlled trials in men with a diagnosis of CP/CPPS. We included all available non-pharmacological interventions. Two review authors independently classified studies and abstracted data from the included studies, performed statistical analyses and rated quality of evidence (QoE) according to the Grading of Recommendations Assessment, Development and Evaluation methods. The primary outcomes were prostatitis symptoms and adverse events. The secondary outcomes were sexual dysfunction, urinary symptoms, quality of life, anxiety and depression.

RESULTS

We included 38 unique studies in 3290 men with CP/CPPS across 23 comparisons, reporting outcomes mostly at short-term follow-up. Our analysis showed that acupuncture probably leads to clinically meaningful reduction in prostatitis symptoms compared with a sham procedure (mean difference [MD] in total National Institutes of Health - Chronic Prostatitis Symptom Index [NIH-CPSI] score -5.79, 95% confidence interval [CI] -7.32 to -4.26, moderate QoE). Acupuncture may result in little or no difference in adverse events (low QoE). Acupuncture may also lead to a clinically meaningful reduction in prostatitis symptoms compared with standard medical therapy (MD -6.05, 95% CI -7.87 to -4.24, two studies, 78 participants, low QoE). Lifestyle modifications may be associated with a reduction in prostatitis symptoms compared with control (risk ratio for improvement in NIH-CPSI scores 3.90, 95% CI 2.20 to 6.92, very low QoE), but we found no information regarding adverse events. A physical activity programme may cause a small reduction in prostatitis symptoms compared with control (NIH-CPSI score MD -2.50, 95% CI -4.69 to -0.31, low QoE), but we found no information regarding adverse events. It was uncertain whether prostatic massage reduces or increases prostatitis symptoms compared with control (very low QoE) and we found no information regarding adverse events. Extracorporeal shockwave therapy reduces prostatitis symptoms compared with control (NIH-CPSI score MD -6.18, 95% CI -7.46 to -4.89, high QoE), but these results may not be sustained at medium-term follow-up (low QoE). This treatment may not be associated with a greater incidence of adverse events (low QoE). Transrectal thermotherapy, alone or in combination with medical therapy, may decrease prostatitis symptoms slightly when compared with medical therapy alone (NIH-CPSI score MD -2.50, 95% CI -3.82 to -1.18, low QoE). One included study reported that participants may experience transient adverse events.

CONCLUSIONS

Based on the findings with moderate to high QoE, this review found that some non-pharmacological interventions, such as acupuncture and extracorporeal shockwave therapy, are likely to result in a decrease in prostatitis symptoms and may not be associated with a greater incidence of adverse events. The QoE for most other comparisons was predominantly low. Future clinical trials should include a full report of their methods, including adequate masking, consistent assessment of all patient-important outcomes including potential treatment-related adverse events and appropriate sample sizes.

Non-pharmacological interventions for treating chronic prostatitis/chronic pelvic pain syndrome

BACKGROUND

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disorder in which the two main clinical features are pelvic pain and lower urinary tract symptoms. There are currently many approaches for its management, using both pharmacological and non-pharmacological interventions. The National Institute of Health - Chronic Prostatitis Symptom Index (NIH-CPSI) score is a validated measure commonly used to measure CP/CPPS symptoms.

OBJECTIVES

To assess the effects of non-pharmacological therapies for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).

SEARCH METHODS

We performed a comprehensive search using multiple databases, trial registries, grey literature and conference proceedings with no restrictions on the language of publication or publication status. The date of the latest search of all databases was August 2017.

SELECTION CRITERIA

We included randomised controlled trials. Inclusion criteria were men with a diagnosis of CP/CPPS. We included all available non-pharmacological interventions.

DATA COLLECTION AND ANALYSIS

Two review authors independently classified studies and abstracted data from the included studies, performed statistical analyses and rated quality of evidence (QoE) according to the GRADE methods.

MAIN RESULTS

We included 38 unique studies with 3290 men with CP/CPPS across 23 comparisons.1. Acupuncture: (three studies, 204 participants) based on short-term follow-up, acupuncture probably leads to clinically meaningful reduction in prostatitis symptoms compared with sham procedure (mean difference (MD) in total NIH-CPSI score -5.79, 95% confidence interval (CI) -7.32 to -4.26, high QoE). Acupuncture may result in little to no difference in adverse events (low QoE). Acupuncture may not reduce sexual dysfunction when compared with sham procedure (MD in the International Index of Erectile Function (IIEF) Scale -0.50, 95% CI -3.46 to 2.46, low QoE). Acupuncture may also lead to a clinically meaningful reduction in prostatitis symptoms compared with standard medical therapy (MD -6.05, 95% CI -7.87 to -4.24, two studies, 78 participants, low QoE). We found no information regarding quality of life, depression or anxiety.2. Lifestyle modifications: (one study, 100 participants) based on short-term follow-up, lifestyle modifications may be associated with a reduction in prostatitis symptoms compared with control (risk ratio (RR) for improvement in NIH-CPSI scores 3.90, 95% CI 2.20 to 6.92, very low QoE). We found no information regarding adverse events, sexual dysfunction, quality of life, depression or anxiety.3. Physical activity: (one study, 85 participants) based on short-term follow-up, a physical activity programme may cause a small reduction in prostatitis symptoms compared with control (NIH-CPSI score MD -2.50, 95% CI -4.69 to -0.31, low QoE). This programme may not reduce anxiety or depression (low QoE). We found no information regarding adverse events, sexual dysfunction or quality of life.4. Prostatic massage: (two studies, 115 participants) based on short-term follow-up, we are uncertain whether the prostatic massage reduces or increases prostatitis symptoms compared with control (very low QoE). We found no information regarding adverse events, sexual dysfunction, quality of life, depression or anxiety.5. Extracorporeal shockwave therapy: (three studies, 157 participants) based on short-term follow-up, extracorporeal shockwave therapy reduces prostatitis symptoms compared with control (NIH-CPSI score MD -6.18, 95% CI -7.46 to -4.89, high QoE). These results may not be sustained at medium-term follow-up (low QoE). This treatment may not be associated with a greater incidence of adverse events (low QoE). This treatment probably improves sexual dysfunction (MD in the IIEF Scale MD 3.34, 95% CI 2.68 to 4.00, one study, 60 participants, moderate QoE). We found no information regarding quality of life, depression or anxiety.6. Transrectal thermotherapy compared to medical therapy: (two studies, 237 participants) based on short-term follow-up, transrectal thermotherapy alone or in combination with medical therapy may decrease prostatitis symptoms slightly when compared with medical therapy alone (NIH-CPSI score MD -2.50, 95% CI -3.82 to -1.18, low QoE). One included study reported that participants may experience transient adverse events. We found no information regarding sexual dysfunction, quality of life, depression or anxiety.7. Other interventions: there is uncertainty about the effects of most of the other interventions included in this review. We found no information regarding psychological support or prostatic surgery.

AUTHORS' CONCLUSIONS

Based on the findings of moderate quality evidence, this review found that some non-pharmacological interventions such as acupuncture and extracorporeal shockwave therapy are likely to result in a decrease in prostatitis symptoms and may not be associated with a greater incidence of adverse event. The QoE for most other comparisons was predominantly low. Future clinical trials should include a full report of their methods including adequate masking, consistent assessment of all patient-important outcomes including potential treatment-related adverse events and appropriate sample sizes.

Acupuncture for Chronic Prostatitis/Chronic Pelvic Pain Syndrome: A Randomized, Sham Acupuncture Controlled Trial

PURPOSE

We investigated the effectiveness of acupuncture in patients with chronic prostatitis/chronic pelvic pain syndrome.

MATERIALS AND METHODS

We performed this 32-week randomized, controlled trial with 8 weeks of treatment followed by 24 weeks of followup to compare acupuncture with sham acupuncture. Participants with chronic prostatitis/chronic pelvic pain syndrome were randomly assigned to acupuncture or noninvasive sham acupuncture. The primary outcome was the change in the NIH-CPSI (National Institutes of Health Chronic Prostatitis Symptom Index) total score from baseline to week 8. Secondary outcomes were the NIH-CPSI subscale scores, pain severity, the I-PSS (International Prostate Symptom Score), the global response rate and satisfaction assessment.

RESULTS

A total of 68 participants 18 to 50 years old were enrolled and included in intent to treat analyses. Baseline characteristics were comparable in the 2 groups. The reduction in the NIH-CPSI total score differed significantly between the 2 groups at weeks 8, 20 and 32 with a difference of -5.7 (95% CI -7.8--3.7), -6.7 (95% CI -8.9--4.5) and -7.4 (95% CI -9.8--5.1), respectively (each p <0.001). All differences were greater than the 4-point minimal clinically important difference. No significant difference was found between the groups in NIH-CPSI pain and quality of life subscale scores or in I-PSS at week 4 (each p >0.05). For all other secondary outcomes the acupuncture group was statistically better than the sham acupuncture group.

CONCLUSIONS

Acupuncture showed clinical and long-lasting benefits compared with sham acupuncture for chronic prostatitis/chronic pelvic pain syndrome. Randomized controlled trials with larger sample sizes are needed in the future.

DATA COLLECTION AND ANALYSIS

Two review authors independently classified studies and abstracted data from the included studies, performed statistical analyses and rated quality of evidence (QoE) according to the GRADE methods.

MAIN RESULTS

We included 38 unique studies with 3290 men with CP/CPPS across 23 comparisons.1. Acupuncture: (three studies, 204 participants) based on short-term follow-up, acupuncture reduces prostatitis symptoms in an appreciable number of participants compared with sham procedure (mean difference (MD) in total NIH-CPSI score -5.79, 95% confidence interval (CI) -7.32 to -4.26, high QoE). Acupuncture likely results in little to no difference in adverse events (moderate QoE). It probably also decreases prostatitis symptoms compared with standard medical therapy in an appreciable number of participants (MD -6.05, 95% CI -7.87 to -4.24, two studies, 78 participants, moderate QoE).2. Circumcision: (one study, 713 participants) based on short-term follow-up, early circumcision probably decreases prostatitis symptoms slightly (NIH-CPSI score MD -3.00, 95% CI -3.82 to -2.18, moderate QoE) and may not be associated with a greater incidence of adverse events compared with control (a waiting list to be circumcised, low QoE).3. Electromagnetic chair: (two studies, 57 participants) based on short-term follow-up, we are uncertain of the effects of the use of an electromagnetic chair on prostatitis symptoms. It may be associated with a greater incidence of adverse events compared with sham procedure (low to very low QoE).4. Lifestyle modifications: (one study, 100 participants) based on short-term follow-up, lifestyle modifications may be associated with a greater improvement in prostatitis symptoms in an appreciable number of participants compared with control (risk ratio (RR) for improvement in NIH-CPSI scores 3.90, 95% CI 2.20 to 6.92, very low QoE). We found no information regarding adverse events.5. Physical activity: (one study, 85 participants) based on short-term follow-up, a physical activity programme may cause a small reduction in prostatitis symptoms compared with control (NIH-CPSI score MD -2.50, 95% CI -4.69 to -0.31, low QoE). We found no information regarding adverse events.6. Prostatic massage: (two studies, 115 participants) based on short-term follow-up, we are uncertain whether the prostatic massage reduces or increases prostatitis symptoms compared with control (very low QoE). We found no information regarding adverse events.7. Extracorporeal shockwave therapy: (three studies, 157 participants) based on short-term follow-up, extracorporeal shockwave therapy reduces prostatitis symptoms compared with control (NIH-CPSI score MD -6.18, 95% CI -7.46 to -4.89, high QoE). These results may not be sustained at medium-term follow-up (low QoE). This treatment may not be associated with a greater incidence of adverse events (low QoE).8. Transrectal thermotherapy compared to medical therapy: (two studies, 237 participants) based on short-term follow-up, transrectal thermotherapy alone or in combination with medical therapy may decrease prostatitis symptoms slightly when compared with medical therapy alone (NIH-CPSI score MD -2.50, 95% CI -3.82 to -1.18, low QoE). One included study reported that participants may experience transient adverse events.9. Other interventions: there is uncertainty about the effects of other interventions included in this review. We found no information regarding psychological support or prostatic surgery.

AUTHORS' CONCLUSIONS

Some of the interventions can decrease prostatitis symptoms in an appreciable number without a greater incidence of adverse events. The QoE was mostly low. Future clinical trials should include a full report of their methods including adequate masking, consistent assessment of all patient-important outcomes including potential treatment-related adverse events and appropriate sample sizes.

Acupuncture for chronic prostatitis/chronic pelvic pain syndrome: study protocol for a randomized controlled trial

Background

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common condition affecting men of all ages. Acupuncture may be an effective treatment option for CP/CPPS, but evidence is limited. We propose to evaluate the effectiveness of acupuncture in a rigorously conducted trial.

Methods

Ten hospitals will recruit 440 participants with CP/CPPS in China from October 2017 to December 2019. Participants will be randomly allocated to acupuncture or sham acupuncture with a 1:1 ratio using computerized simple random sampling. The whole study consists of 2-week baseline, 8-week treatment, and 24-week follow up. Twenty 30-mintute sessions of acupuncture or sham acupuncture treatment will be provided between week 1 and 8. The two co-primary outcomes are the proportion of responders at week 8 and week 32. Secondary outcomes include proportion of responders in the two groups at different time points; change in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score; change in the NIH-CPSI subscales; change in the International Prostate Symptom Score; change in the Hospital Anxiety and Depression Scale; expectation assessments; proportions of participants in each response category of the Global Response Assessment; change in the International Index of Erectile Function 5; change in the five-level EuroQol five-dimensional questionnaire and a visual analogue scale; and changes in peak and average urinary flow rate.

Discussion

This study will provide robust evidence on whether acupuncture is effective for relieving symptoms of CP/CPPS.

Cupping therapy versus acupuncture for pain-related conditions: a systematic review of randomized controlled trials and trial sequential analysis

Background

Both cupping therapy and acupuncture have been used in China for a long time, and their target indications are pain-related conditions. There is no systematic review comparing the effectiveness of these two therapies.

Objectives

To compare the beneficial effectiveness and safety between cupping therapy and acupuncture for pain-related conditions to provide evidence for clinical practice.

Methods

Protocol of this review was registered in PROSPERO (CRD42016050986). We conducted literature search from six electronic databases until 31st March 2017. We included randomized trials comparing cupping therapy with acupuncture on pain-related conditions. Methodological quality of the included studies was evaluated by risk of bias tool. Mean difference, risk ratio, risk difference and their 95% confidence interval were used to report the estimate effect of the pooled results through meta-analysis or the results from each individual study. Trial sequential analysis (TSA) was applied to adjust random errors and calculate the sample size.

Results

Twenty-three randomized trials with 2845 participants were included covering 12 pain-related conditions. All included studies were of poor methodological quality. Three meta-analyses were conducted, which showed similar clinical beneficial effects of cupping therapy and acupuncture for the rate of symptom improvement in cervical spondylosis (RR 1.13, 95% CI 1.01 to 1.26; n = 646), lateral femoral cutaneous neuritis (RR 1.10, 95% CI 1.00 to 1.22; n = 102) and scapulohumeral periarthritis (RR 1.31, 95% CI 1.15 to 1.51; n = 208). Results from other outcomes (such as visual analogue and numerical rating scale) in each study also showed no statistical significant difference between these two therapies for all included pain-related conditions. The results of TSA for cervical spondylosis demonstrated that the current available data have not reached a powerful conclusion. No serious adverse events related to cupping therapy or acupuncture was found in included studies.

Conclusion

Cupping therapy and acupuncture are potentially safe, and they have similar effectiveness in relieving pain. However, further rigorous studies investigating relevant pain-related conditions are warranted to establish comparative effectiveness analysis between these two therapies. Cost-effectiveness studies should be considered in the future studies to establish evidence for decision-making in clinical practice.
