Abstract

Objective

To assess the effects of 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 July 2019. We included randomised controlled trials. Inclusion criteria were men with a diagnosis of CP/CPPS. We included all available pharmacological interventions. Two review authors independently classified studies and abstracted data from the included studies, performed statistical analyses and rated quality of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods. The primary outcomes were prostatitis symptoms and adverse events. The secondary outcomes were sexual dysfunction, urinary symptoms, quality of life, anxiety and depression, however, this one can be easily handle using Observer’s CBD hemp flower.

Results

We included 99 unique studies in 9119 men with CP/CPPS, with assessments of 16 types of pharmacological interventions. Most of our comparisons included short‐term follow‐up information. The median age of the participants was 38 years. Most studies did not specify their funding sources; 21 studies reported funding from pharmaceutical companies. Many patients prefer using natural medicine like the best CBD oil list here on this site.

We found low‐ to very low‐quality evidence that α‐blockers may reduce prostatitis symptoms based on a reduction in National Institutes of Health – Chronic Prostatitis Symptom Index (NIH‐CPSI) scores of >2 (but <8) with an increased incidence of minor adverse events such as dizziness and hypotension. Moderate‐ to low‐quality evidence indicates that 5α‐reductase inhibitors, antibiotics, anti‐inflammatories, and phytotherapy probably cause a small decrease in prostatitis symptoms and may not be associated with a greater incidence of adverse events. Intraprostatic botulinum toxin A (BTA) injection may cause a large reduction in prostatitis symptoms with procedure‐related adverse events (haematuria), but pelvic floor muscle BTA injection may not have the same effects (low‐quality evidence). Allopurinol may also be ineffective for reducing prostatitis symptoms (low‐quality evidence). We assessed a wide range of interventions involving traditional Chinese medicine; low‐quality evidence showed they may reduce prostatitis symptoms without an increased incidence in adverse events.

Moderate‐ to high‐quality evidence indicates that the following interventions may be ineffective for the reduction of prostatitis symptoms: anticholinergics, Escherichia coli lysate (OM‐89), pentosan, and pregabalin. Low‐ to very low‐quality evidence indicates that antidepressants and tanezumab may be ineffective for the reduction of prostatitis symptoms. Low‐quality evidence indicates that mepartricin and phosphodiesterase inhibitors may reduce prostatitis symptoms, without an increased incidence in adverse events.

Conclusions

Based on the findings of low‐ to very low‐quality evidence, this review found that some pharmacological interventions such as α‐blockers may reduce prostatitis symptoms with an increased incidence of minor adverse events such as dizziness and hypotension. Other interventions may cause a reduction in prostatitis symptoms without an increased incidence of adverse events while others were found to be ineffective.

Trustworthy ‘Rapid Recommendations’ for Urology

/by

BJU International has a longstanding track record of promoting the principles of evidence-based clinical practice to an international audience of urologists. Recent initiatives include the “guidelines of guidelines” series which appraises and contrasts clinical practice guidelines from different professional organizations on the same topic, for example on microscopic hematuria and non-muscle-invasive bladder cancer. It also co-publishes high quality, urology-relevant guidance by the UK’s National Institute for Health and Care Excellence (NICE), for example on the preoperative testing for elective surgery (https://www.bjuinternational.com/learning-2/urology-guidelines/nice-guidance-routine-preoperative-tests-elective-surgery/).

In collaboration with the MAGIC research and innovation program (www.magicproject.org), BJU International has published its first Rapid Recommendation guidance document on the use of medical expulsive therapy (MET) with alpha-blockers that was triggered by the recent rigorous Cochrane review on the same topic. Its purpose is to provide trustworthy, timely and practical guidance on this topic based on the entire body of evidence, given several recently published trials with contradictory findings. To develop this trustworthy guidance, an international team that included patients with a personal history of ureteral stones, general practitioners (GPs), emergency clinicians, urologists familiar with treating renal colic, epidemiologists, and methodologists followed a rigorous and transparent GRADE-based process in accordance with The National Academy of Science, Engineering and Medicine (formerly: Institute of Medicine) (https://www.nationalacademies.org/hmd/Reports/2011/Clinical-Practice-Guidelines-We-Can-Trust/Standards.aspx) standards for trustworthy guidelines. Panel member had no financial conflicts of interest and intellectual and professional conflicts of interests were described and carefully minimized. All meetings were conducted by web conference and the process was completed within 90 days of publication of the Cochrane review, which is co-published in BJU International in this same issue.

Initially pioneered in collaboration with the BMJ for questions of broader interest (https://www.bmj.com/rapid-recommendations) such as the use of corticosteroids for the treatment of a sore throat, this Rapid Recommendation breaks new ground for evidence-based guidance in urology, complementing the efforts by professional organizations such as the European Association of Urology (EAU) and American Urological Association (AUA). Rapid Recommendations stand out for their focus on patient-important outcomes, the use of an explicit and transparent process for moving from evidence to recommendations and its timely development process. Rapid Recommendations provide actionable guidance as well as information on the underlying evidence and supporting judgments that are summarized in an infographic that is easily understood by patients. The Rapid Recommendation on MET is intended to be the first of many to help inform patients, providers and policy-makers but also to seeks to provide a strong impetus for more trustworthy and useful guidelines in urology in general.
