Outcomes and clinical predictors of extracorporeal shock wave therapy in the treatment of chronic prostatitis/chronic pelvic pain syndrome: a prospective randomized double-blind placebo-controlled clinical trial. Prostate Cancer Prostatic Dis 2022; 25:93-99. [PMID: 34635804 DOI: 10.1038/s41391-021-00464-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Revised: 09/18/2021] [Accepted: 09/23/2021] [Indexed: 02/04/2023]
Abstract
OBJECTIVES To report the one-year results of ESWT on CPPS patients and the possible clinical characteristics that may affect its efficacy. PATIENTS & METHODS A prospective randomized clinical study between January 2017 and January 2021 on 155 adult patients with chronic pelvic pain syndrome. All patients were initially evaluated with a thorough history and physical examination. Baseline symptoms evaluation of each participant was assessed using NIH-CPSI score, IPSS, VAS, and IIEF-5 score. Patients were randomized into two groups: a verum treatment group and a placebo treatment group. Patients of verum group in the lithotomy position received a perineally applied ESWT treatment once a week for four weeks with 3000 impulses each. Patients of placebo group received the same therapy head of the same device with a layer of air-filled microspheres to absorb the shock waves. The previously mentioned validated scores were reassessed on regular follow-up visits at one, three, six, and 12 months after the completion of ESWT. RESULTS A statistically significant improvement was noticed in the mean values of NIH-CPSI, IPSS, VAS, and IIEF-5 of the patients of verum group over the follow-up period with also statistically significant difference between both groups. At the first visit of follow-up after ESWT, 63 (82.8%) patients had ≥6 points decrease in the NIH-CPSI total score, while 13 (17.2%) patients did not. Univariate and multivariate analyses of the clinical characteristics between the responders and non-responders showed that those patients with history of psychological disorders or had higher initial NIH-CPSI score had a significantly lower response rate to ESWT (p = 0.005, 0.02 & p = 0.002, 0.004 respectively). ROC curve of NIH-CPSI score showed that a score of 32 was the cut-off point above which the response to ESWT decreased. CONCLUSION ESWT is an effective treatment option for CPPS. Its efficacy remained throughout long-term follow up. High initial NIH-CPSI score and history of psychological problems are significant predictors for it.

Botulinum Toxin-A Injection in Chronic Pelvic Pain Syndrome Treatment: A Systematic Review and Pooled Meta-Analysis. Toxins (Basel) 2022; 14:toxins14010025. [PMID: 35051002 PMCID: PMC8780260 DOI: 10.3390/toxins14010025] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2021] [Revised: 12/17/2021] [Accepted: 12/27/2021] [Indexed: 12/24/2022] Open
Abstract
Introduction: Pain management of patients with chronic pelvic pain syndrome (CPPS) is challenging, because pain is often refractory to conventional treatments. Botulinum toxin A (BTX-A) may represent a promising therapeutic strategy for these patients. The aim of this systematic review was to investigate the role of BTX-A in CPPS treatment. Methods: We reviewed the literature for prospective studies evaluating the use of BTX-A in the treatment of CPPS. A comprehensive search in the PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials databases was performed from English language articles published between January 2000 and October 2021. The primary outcome was to evaluate pain improvement in CPPS after BTX-A treatment. Pooled meta-analysis of the included studies, considering the effect of BTX-A on pain evaluated at last available follow-up compared to baseline values, was performed together with meta-regression analysis. Results: After screening 1001 records, 18 full-text manuscripts were selected, comprising 13 randomized clinical trials and five comparative studies. They covered overall 896 patients of both sexes and several subtype of CPPS (interstitial cystitis/bladder pain syndrome, chronic prostatitis/prostate pain syndrome, chronic scrotal pain, gynecological pelvic pain, myofascial pelvic pain). The clinical and methodological heterogeneity of studies included makes it difficult to do an overall estimation of the real effect of BTX-A on pain and other functional outcomes of various CPPS subtypes. However, considering pooled meta-analysis results, a benefit in pain relief was showed for BTX-A-treated patients both in the overall studies populations and in the overall cohorts of patients with CPP due to bladder, prostate, and gynecological origin. Conclusions: BTX-A could be an efficacious treatment for some specific CPPS subtypes. Higher level studies are needed to assess the efficacy and safety of BTX-A and provide objective indications for its use in CPPS management.

Abstract
CONTEXT Patients with chronic pelvic pain syndrome (CPPS) may have pain refractory to conventional management strategies. Botulinum toxin A (BTX-A) is a potential therapeutic option. OBJECTIVE To evaluate the benefits and harms of BTX-A injections in the treatment of CPPS. EVIDENCE ACQUISITION A systematic review of the use of BTX-A in the treatment of CPPS was conducted (PROSPERO-ID: 162416). Comprehensive searches of EMBASE, PUBMED, Medline, and SCOPUS were performed for publications between January 1996 and May 2020. Identified studies were screened and selected studies assessed for quality prior to data extraction. The primary outcomes were improvement in pain and adverse events following treatment. Secondary outcomes included quality of life, global response assessment, sexual function, bowel function, and bladder function. EVIDENCE SYNTHESIS After screening 1001 abstracts, 16 studies including 11 randomised controlled trials were identified, enrolling 858 patients and covering a range of CPPS subtypes. Most studies showed high risks of bias and confounding across all domains. A narrative synthesis was performed as heterogeneity of included studies precluded a meta-analysis and calculation of pooled effect estimates of measured outcomes. BTX-A reduced pain significantly in patients with bladder pain syndrome in two studies and in patients with prostate pain syndrome in one study, but no included studies showed benefit for patients with gynaecological pelvic pain. Adverse event reporting was variable and generally poor, but no serious adverse events were described. CONCLUSIONS Beneficial effects of BTX-A on pain, quality of life, and functional symptoms were seen in patients with certain CPPS subtypes, but the current evidence level is too weak to allow recommendations about BTX-A use for treating CPPS. PATIENT SUMMARY Botulinum toxin A is used to treat different pain disorders, but current studies are of insufficient quality to determine whether it reduces pain and improves quality of life in patients with chronic pelvic pain. Further research is needed.

Abstract
INTRODUCTION Botulinum neurotoxin (BoNT) is a recognized therapeutic agent of modern medical care, routinely used to treat medical conditions affecting a variety of organ systems including the musculoskeletal, integumentary, and urological domains. Ongoing research is exploring BoNT's potential role as a therapeutic agent for a variety of male sexual pathologies. OBJECTIVE To review and analyze the literature regarding BoNT as a treatment option for male sexual dysfunction. METHODS A PubMed search was performed for English-language articles in peer-reviewed journals between 1970 and 2019 (with one article from 1897). Relevant articles referenced within these texts were also included. One article did not have an accompanied English full-text available. The following search terms were used: "Botox", "Botulinum toxin", "Botulinum toxin A", "Onabotulinum A", "Abobutlinum A", "BoNT", "BoNT-A", "Male sexual health", "Male sexual pathology", "Peyronie's disease", "Premature ejaculation", "Scrotal Pain", "Penile Retraction", "Scrotox", "Erectile Dysfunction", and "Botox in Urology". RESULTS There is interest in the potential role of BoNT in the treatment of male sexual pathologies. We identified studies that used BoNT to treat chronic scrotal content pain, premature ejaculation, erectile dysfunction, Peyronie's disease, penile retraction, and more. However, despite preclinical/clinical data indicating some potential efficacy and safety in these settings, a lack of robust clinical trial data has resulted in no current Food and Drug Administration-approved indications for the use of BoNT in the treatment of male sexual pathology. As a result, much of the current use of BoNT by today's providers is "off-label," and ongoing clinical trials aim to further elucidate the potential role of this therapeutic agent. CONCLUSION Current data suggest that BoNT could have a potential role as a treatment option for certain types of male sexual pathologies. However, more randomized controlled trial data regarding its long-term safety and efficacy are necessary before a widespread clinical adoption can take place. Reddy AG, Dick BP, Natale C, et al.

Abstract
INTRODUCTION The assessment of pelvic floor muscle (PFM) overactivity is part of a comprehensive evaluation including a detailed history (medical, gynecological history/antecedent), appraisal of the psychosocial contexts of the patient, as well as a musculoskeletal and a neurological examination. OBJECTIVES The aims of this article are to review (i) the assessment modalities evaluating pelvic floor function in women and men with disorders associated with an overactive pelvic floor (OPF), and (ii) therapeutic approaches to address OPF, with particular emphases on sexual pain and function. METHODS We outline assessment tools that evaluate psychological and cognitive states. We then review the assessment techniques to evaluate PFM involvement including digital palpation, electromyography, manometry, ultrasonography, and dynamometry, including an overview of the indications, efficacy, advantages, and limitations of each instrument. We consider each instrument's utility in research and in clinical settings. We next review the evidence for medical, physiotherapy, and psychological interventions for OPF-related conditions. RESULTS Research using these assessment techniques consistently points to findings of high PFM tone among women and men reporting disorders associated with OPF. While higher levels of evidence are needed, options for medical treatment include diazepam suppositories, botulinum toxin A, and other muscle relaxants. Effective psychological therapies include cognitive behavioral therapy, couple therapy, mindfulness, and educational interventions. Effective physiotherapy approaches include PFM exercise with biofeedback, electrotherapy, manual therapy, and the use of dilators. Multimodal approaches have demonstrated efficacy in reducing pain, normalizing PFM tone, and improving sexual function. Multidisciplinary interventions and an integrative approach to the assessment and management of OPF using a biopsychosocial framework are discussed. CONCLUSION Although the efficacy of various intervention approaches has been demonstrated, further studies are needed to personalize interventions according to a thorough assessment and determine the optimal combination of psychological, physical, and behavioral modalities.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/ CPPS) has a negative impact on the quality of life, and its etiology still remains unknown. Although many treatment protocols have been evaluated in CP/CPPS, the outcomes have usually been disappointing. Botulinum neurotoxin A (BoNT-A), produced from Clostridium botulinum, has been widely used to lower urinary tract dysfunctions such as detrusor sphincter dyssynergia, refractory overactive bladder, interstitial cystitis/bladder pain syndromes, benign prostatic hyperplasia, and CP/ CPPS in urology. Here, we review the published evidence from animal models to clinical studies for inferring the mechanism of action underlying the therapeutic efficacy of BoNT in CP/CPPS. Animal studies demonstrated that BoNT-A, a potent inhibitor of neuroexocytosis, impacts the release of sensory neurotransmitters and inflammatory mediators. This pharmacological action of BoNT-A showed promise of relieving the pain of CP/CPPS in placebo-controlled and open-label BoNT-A and has the potential to serve as an adjunct treatment for achieving better treatment outcomes in CP/CPPS patients.

Abstract
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. We considered a 25% decrease of NIH-CPSI baseline score or a six-point reduction as MCID. OBJECTIVES To assess the effects of pharmacological therapies for chronic prostatitis/chronic pelvic pain syndrome. SEARCH METHODS We performed a comprehensive search using CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, 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 July 2019. SELECTION CRITERIA We included randomised controlled trials. Inclusion criteria were men with a diagnosis of CP/CPPS. We included all available pharmacological interventions compared to placebo or in head-to-head comparisons. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study eligibility, extracted data, and assessed the risks of bias of included studies. We assessed the quality of the evidence (QoE) using the GRADE approach. MAIN RESULTS We included 99 unique studies in 9119 men with CP/CPPS, with assessments of 16 types of pharmacological interventions. Unless stated otherwise, our comparisons were based on short-term follow-up (less than 12 months). Most studies did not specify their funding sources; 21 studies reported funding from pharmaceutical companies.1. Alpha blockers: (24 studies, 2061 participants). We are uncertain about the effects of these drugs on prostatitis symptoms when compared to placebo at short-term follow-up (mean difference (MD) in total NIH-CPSI score -5.01, 95% confidence interval (CI) -7.41 to -2.61; 18 studies, 1524 participants, very low QoE) and at long-term follow-up (MD -5.60, 95% CI -10.89 to -0.32; 4 studies, 235 participants, very low QoE). Alpha blockers may be associated with an increased incidence of adverse events, such as dizziness and postural hypotension (risk ratio (RR) 1.60, 95% CI 1.09 to 2.34; 19 studies, 1588 participants; low QoE). Alpha blockers probably result in little to no difference in sexual dysfunction, quality of life and anxiety and depression (moderate to low QoE).2. 5-alpha reductase inhibitors (5-ARI): (2 studies, 177 participants). Finasteride probably reduces prostatitis symptoms compared to placebo (NIH-CPSI score MD -4.60, 95% CI -5.43 to -3.77; 1 study, 64 participants; moderate QoE) and may not be associated with an increased incidence of adverse events (low QoE). There was no information on sexual dysfunction, quality of life or anxiety and depression.3. Antibiotics: (6 studies, 693 participants). Antibiotics (quinolones) may reduce prostatitis symptoms compared to placebo (NIH-CPSI score MD -2.43, 95% CI -4.72 to -0.15; 5 studies, 372 participants; low QoE) and are probably not associated with an increased incidence in adverse events (moderate QoE). Antibiotics probably result in little to no difference in sexual dysfunction and quality of life (moderate QoE). There was no information on anxiety or depression.4. Anti-inflammatories: (7 studies, 585 participants). Anti-inflammatories may reduce prostatitis symptoms compared to placebo (NIH-CPSI scores MD -2.50, 95% CI -3.74 to -1.26; 7 studies, 585 participants; low QoE) and may not be associated with an increased incidence in adverse events (low QoE). There was no information on sexual dysfunction, quality of life or anxiety and depression.5. Phytotherapy: (7 studies, 551 participants). Phytotherapy may reduce prostatitis symptoms compared to placebo (NIH-CPSI scores MD -5.02, 95% CI -6.81 to -3.23; 5 studies, 320 participants; low QoE) and may not be associated with an increased incidence in adverse events (low QoE). Phytotherapy may not improve sexual dysfunction (low QoE). There was no information on quality of life or anxiety and depression.6. Botulinum toxin A (BTA): Intraprostatic BTA injection (1 study, 60 participants) may cause a large reduction in prostatitis symptom (NIH-CPSI scores MD -25.80, 95% CI -30.15 to -21.45), whereas pelvic floor muscle BTA injection (1 study, 29 participants) may not reduce prostatitis symptoms (low QoE). Both comparisons used a placebo injection. These interventions may not be associated with an increased incidence in adverse events (low QoE). There was no information on sexual dysfunction, quality of life or anxiety and depression.7. Allopurinol: (2 studies, 110 participants). Allopurinol may result in little to no difference in prostatitis symptoms and adverse events when compared to placebo (low QoE). There was no information on sexual dysfunction, quality of life or anxiety and depression.8. Traditional Chinese medicine (TCM): (7 studies, 835 participants); TCM may reduce prostatitis symptoms (NIH-CPSI score, MD -3.13, 95% CI -4.99 to -1.28; low QoE) and may not be associated with an increased incidence in adverse events (low QoE). TCM probably does not improve sexual dysfunction (moderate QoE) and may not improve symptoms of anxiety and depression (low QoE). There was no information on quality of life.The most frequent reasons for downgrading the QoE were study limitations, inconsistency and imprecision. We found few trials with active comparators. AUTHORS' CONCLUSIONS We found low- to very low-quality evidence that alpha blockers, antibiotics, 5-ARI, anti-inflammatories, phytotherapy, intraprostatic BTA injection, and traditional Chinese medicine may cause a reduction in prostatitis symptoms without an increased incidence of adverse events in the short term, except for alpha blockers which may be associated with an increase in mild adverse events. We found few trials with active comparators and little evidence of the effects of these drugs on sexual dysfunction, quality of life or anxiety and depression. 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.

Can Botulinum Toxin A Still Have a Role in Treatment of Lower Urinary Tract Symptoms/Benign Prostatic Hyperplasia Through Inhibition of Chronic Prostatic Inflammation? Toxins (Basel) 2019; 11:toxins11090547. [PMID: 31546892 PMCID: PMC6784075 DOI: 10.3390/toxins11090547] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Revised: 09/12/2019] [Accepted: 09/17/2019] [Indexed: 11/16/2022] Open
Abstract
Patients with benign prostatic hyperplasia (BPH) can exhibit various lower urinary tract symptoms (LUTS) owing to bladder outlet obstruction (BOO), prostatic inflammation, and bladder response to BOO. The pathogenesis of BPH involves an imbalance of internal hormones and chronic prostatic inflammation, possibly triggered by prostatic infection, autoimmune responses, neurogenic inflammation, oxidative stress, and autonomic dysfunction. Botulinum toxin A (BoNT-A) is well recognized for its ability to block acetylcholine release at the neuromuscular junction by cleaving synaptosomal-associated proteins. Although current large clinical trials have shown no clinical benefits of BoNT-A for the management of LUTS due to BPH, BoNT-A has demonstrated beneficial effects in certain subsets of BPH patients with LUTS, especially in males with concomitant chronic prostatitis/chronic pelvic pain syndrome and smaller prostate. We conducted a review of published literature in Pubmed, using Botulinum toxin, BPH, BOO, inflammation, LUTS, and prostatitis as the key words. This article reviewed the mechanisms of BPH pathogenesis and anti-inflammatory effects of BoNT-A. The results suggested that to achieve effectiveness, the treatment of BPH with BoNT-A should be tailored according to more detailed clinical information and reliable biomarkers.

Abstract
Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a frustrating syndrome. The pathogenesis and state of the art treatment of CP/CPPS are not known. A wide variety of therapies including anti-inflammatories, antibiotics, alpha-blockers, neuropathic pain modulators, and 5α-reductase inhibitors are in practice. These treatment strategies focus on alleviating symptoms in specific domains without treating root-cause and therapeutic outcome is far from satisfactory. We review the literature on current pharmacological treatments for CP/CPPS in detail and suggest future perspectives to modify the treatment strategies. We suggest that introducing novel treatment strategies such as gene editing, and Tregs expressing chimeric receptors may improve the treatment outcomes by inducing immune tolerance and controlling expression of pro-inflammatory cytokines.

Novel Applications of OnabotulinumtoxinA in Lower Urinary Tract Dysfunction. Toxins (Basel) 2018; 10:toxins10070260. [PMID: 29949878 PMCID: PMC6071213 DOI: 10.3390/toxins10070260] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2018] [Revised: 06/20/2018] [Accepted: 06/22/2018] [Indexed: 01/25/2023] Open
Abstract
OnabotulinumtoxinA (BoNT-A) was first used to treat neurogenic lower urinary tract dysfunction (LUTD) 30 years ago. Recently, application of BoNT-A in LUTD have become more common since the approval of intravesical BoNT-A injection for patients with both overactive bladders (OAB) and neurogenic detrusor overactivity (NDO) by regulatory agencies in many countries. Although unlicensed, BoNT-A has been recommended to treat patients with interstitial cystitis/bladder pain syndrome (IC/BPS) under different guidelines. BoNT-A delivery with liposome-encapsulation and gelation hydrogel intravesical instillation provided a potentially less invasive and more convenient form of application for patients with OAB or IC/BPS. BoNT-A injections into the urethral sphincter for spinal cord injury patients with detrusor-sphincter dyssynergia have been used for a long time. New evidence revealed that it could also be applied to patients with non-neurogenic dysfunctional voiding. Previous studies and meta-analyses suggest that BoNT-A injections for patients with benign prostate hyperplasia do not have a better therapeutic effect than placebo. However, new randomized and placebo-controlled trials revealed intraprostatic BoNT-A injection is superior to placebo in specific patients. A recent trial also showed intraprostatic BoNT-A injection could significantly reduce pain in patients with chronic prostatitis. Both careful selection of patients and prudent use of urodynamic evaluation results to confirm diagnoses are essential for successful outcomes of BoNT-A treatment for LUTD.

Abstract
Managing patients with chronic pelvic pain syndrome (CPPS) refractory to the traditional 3-As therapy (antibiotics, alpha-blockers, and anti-inflammatories) is a challenging task. Low-intensity extracorporeal shock wave therapy (LI-ESWT) was recently reported to be able to improve pain, urinary symptoms, and even sexual function by inducing neovascularization and anti-inflammation, reducing muscle tone, and influencing nerve impulses. This study evaluates whether combined treatment with LI-ESWT can restore clinical ability and quality of life (QoL) in patients refractory to 3-As therapy. This was an open-label, single-arm prospective study. Patients with CPPS without more than a 6-point decrease in the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) total score under the maximal dosage of 3-As therapy were enrolled. LI-ESWT treatment consisted of 3,000 shock waves administered once weekly for 4 weeks. The NIH-CPSI, visual analog scale (VAS) score, International Prostate Symptom Score (IPSS), and the five-item version of the International Index of Erectile Function (IIEF-5) were used to evaluate efficacy at 1, 4, and 12 weeks after LI-ESWT. Thirty-three patients were enrolled in this study. After LI-ESWT treatment, 27 of the 33 patients (81.82%) had a successful response to LI-ESWT, with a decrease of 3.29 and 5.97 in the VAS score and total IPSS at the 3-month follow-up. Waist circumference was the only significant predictor of a successful response to LI-ESWT. LI-ESWT can serve as a salvage therapy for patients with CPPS refractory to traditional 3-As therapy. Further studies are needed to determine an adequate therapeutic protocol and important predictors in patients with different CPPS etiologies.

Abstract
Botulinum neurotoxin (BoNT) is used to treat a variety of ailments, and its therapeutic application in lower urinary tract disorders (LUTDs) is well studied. Robust evidence supporting the efficacy and tolerability of BoNT in the treatment of neurogenic detrusor overactivity (NDO) and non-neurogenic overactive bladder (OAB) has led to regulatory approval for these conditions. Use of BoNT in the treatment of interstitial cystitis/bladder pain syndrome, chronic pelvic pain, and detrusor sphincter dyssynergia has demonstrated some promise, but is still evolving and off-label for these indications. Trials to date do not support the use of BoNT for benign prostatic hyperplasia. This comprehensive review outlines the mechanisms of BoNT in the treatment of LUTDs in adults and presents background and updated data examining the efficacy and adverse events associated with the use of BoNT in common urologic applications.
