Chronic Primary Pelvic Pain Syndrome in Men

BACKGROUND

Chronic primary pelvic pain syndrome in men (CPPPSm) can be associated with urogenital pain, urinary symptoms, sexual dysfunction, and emotional disturbance. Its clinical heterogeneity and incompletely understood pathogenesis make it more difficult to treat. This article is intended to familiarize the reader with basic aspects of the manifestations, pathophysiology, diagnostic evaluation, differential diagnosis, and treatment of this condition.

METHODS

This article is based on relevant publications retrieved by a selective search of the literature, including the current guidelines of the European Association of Urology. The features of this disease pertaining to urology, psychosomatic medicine, and pain medicine are illuminated from an interdisciplinary perspective.

RESULTS

Chronic pelvic pain appears to arise through a complex interaction of inflammatory, infectious, neurological, musculoskeletal, and psychosomatic factors. A comprehensive diagnostic work-up should be carried out to evaluate and exclude the numerous differential diagnoses. Treatment strategies are based on the clinical phenotype. Randomized controlled trials have shown that significant relief can be achieved with a variety of drugs and non-pharmacological treatments, selected according to the manifestations of the condition in the individual case. Attention must be paid to treatment-specific adverse effects.

CONCLUSION

The management of patients with CPPPSm should consist of a comprehensive differential diagnostic evaluation and an individually oriented treatment strategy.

Contemporary Management of Chronic Prostatitis

Chronic prostatitis (CP) is a common condition, yet remains a challenge to treat in clinical practice due to the heterogeneity of symptoms. The aim of this article is to undertake a narrative review using key research papers in this field in order to develop a treatment algorithm and research recommendations for the management of type II and type III prostatitis taking a broader look at interventions beyond those recommended in the European Association of Urology Guidelines. A search was performed using multiple databases and trial registries with no language restrictions. Searches were completed on March 1, 2021, with a focus on randomized controlled trials (RCTs), meta-analyses, and systematic reviews. However, in areas with a dearth of such studies, we included case series and observational studies, thus allowing us to assess current levels of evidence and areas of potential research. We identified and reviewed 63 studies. The level of evidence and the quality of trials were assessed and reported. Research recommendations, where applicable, were also highlighted. CP/chronic pelvic pain syndrome (CPPS) is a heterogenous term referring to diverse symptomology that requires tailored treatments depending on the patients' complaints. After a review of the evidence available, we present a treatment algorithm that is based on the much-discussed UPOINT (urinary symptoms, psychosocial dysfunction, organ-specific findings, infection, neurologic/systemic, and tenderness of muscles) framework. Future studies should focus on multimodal therapy based on such frameworks and provide the future direction of this complex condition.

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. 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.

Comprehensive overview of prostatitis

Prostatitis is a common urinary tract syndrome that many doctors find problematic to treat effectively. It is the third most commonly found urinary tract disease in men after prostate cancer and Benign Prostate Hyperplasia (BPH). Prostatitis may account for 25% of all office visits made to the urological clinics complaining about the genital and urinary systems all over the world. In the present study, we classified prostatitis and comprehensively elaborated the etiology, pathogenesis, diagnosis, and treatment of acute bacterial prostatitis (category I), chronic bacterial prostatitis (category II), chronic pelvic pain syndrome (CPPS) (category III), and asymptomatic prostatitis (category IV). In addition, we also tried to get some insights about other types of prostatitis-like fungal, viral and gonococcal prostatitis. The aim of this review is to present the detail current perspective of prostatitis in a single review. To the best of our knowledge currently, there is not a single comprehensive review, which can completely elaborate this important topic in an effective way. Furthermore, this review will provide a solid platform to conduct future studies on different aspects such as risk factors, mechanism of pathogenesis, proper diagnosis, and rational treatment plans for fungal, viral, and gonococcal prostatitis.

Chronic prostatitis: approaches for best management

Prostatitis is a prevalent condition that encompasses a large array of clinical symptoms with significant impacts on men's life. The diagnosis and treatment of this disorder presents numerous challenges for urologists, most notably, a lack of specific and effective diagnostic methods. Chronic bacterial prostatitis is successfully treated with appropriate antibiotics that penetrate the prostate and kill the causative organisms. Prostatitis category III (chronic pelvic pain syndrome) is common, very bothersome, and enigmatic. Symptoms are usually prolonged and, generally speaking, treatment results are unsatisfactory. During the last decade, research has focused on the distress caused by the condition, but although our knowledge has certainly increased, there have been no real breakthroughs; controversies and many unanswered questions remain. Furthermore, the optimal management of category III prostatitis is not known. Conventional prolonged courses of antibiotic therapy have not proven to be efficacious. Novel therapies providing some evidence for efficacy include alpha-blocker, anti-inflammatory phytotherapy, physiotherapy, neuroleptics, and others, each offering therapeutic mechanisms. A stepwise approach involving multimodal therapy is often successful for treating patients. The UPOINT technique has been used to clinically phenotype these patients and drive the appropriate selection of multimodal therapy.
