Objectives
To comprehensively evaluate the efficacy and safety of the hexanic extract of Serenoa repens (HESr, Permixon®; Pierre Fabre Médicament, Castres, France), at a dose of 320 mg daily, as monotherapy for the treatment of lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH).
Materials and methods
We conducted a systematic review and meta‐analysis of randomised controlled trials (RCTs) and prospective observational studies in patients with LUTS/BPH identified through searches in Medline, Web of Knowledge (Institute for Scientific Information), Scopus, the Cochrane Library, and bibliographic references up to March 2017. Articles studying S. repens extracts other than Permixon were excluded. Data were collected on International Prostate Symptom Score (IPSS), maximum urinary flow rate (Qmax), nocturia, quality of life, prostate volume, sexual function, and adverse drug reactions (ADRs). Data obtained from RCTs and observational studies were analysed jointly and separately using a random effects model. A sub‐group analysis was performed of studies that included patients on longer‐term treatment (≥1 year).
Results
Data from 27 studies (15 RCTs and 12 observational studies) were included for meta‐analysis (total N = 5 800). Compared with placebo, the HESr was associated with 0.64 (95% confidence interval [CI] −0.98 to −0.31) fewer voids/night (P < 0.001) and an additional mean increase in Qmax of 2.75 mL/s (95% CI 0.57 to 4.93; P = 0.01). When compared with α‐blockers, the HESr showed similar improvements on IPSS (weighted mean difference [WMD] 0.57, 95% CI −0.27 to 1.42; P = 0.18) and a comparable increase in Qmax to tamsulosin (WMD −0.02, 95% CI −0.71 to 0.66; P = 0.95). Efficacy assessed using the IPSS was similar after 6 months of treatment between the HESr and 5α‐reductase inhibitors (5ARIs). Analysis of all available published data for the HESr showed a mean improvement in IPSS from baseline of −5.73 points (95% CI −6.91 to −4.54; P < 0.001). HESr did not negatively affect sexual function and no clinically relevant effect was observed on prostate‐specific antigen. Prostate volume decreased slightly. Similar efficacy results were seen in patients treated for ≥1 year (n = 447). The HESr had a favourable safety profile, with gastrointestinal disorders being the most frequent ADR (mean incidence of 3.8%).
Conclusion
The present meta‐analysis, which includes all available RCTs and observational studies, shows that the HESr (Permixon) reduced nocturia and improved Qmax compared with placebo and had a similar efficacy to tamsulosin and short‐term 5‐ARI in relieving LUTS. HESr (Permixon) appears to be an efficacious and well‐tolerated therapeutic option for the long‐term medical treatment of LUTS/BPH.
Women having bariatric surgery had lower s25D and higher sPTH. The major determinant of s25D and sPTH was weight. Hyperparathyroidism in obesity did not indicate vitamin D insufficiency. Low s25D was not associated with comorbid conditions, apart from osteoarthritis.
Overactive bladder (OAB) affects an estimated 49 million people in Europe, but only a minority receive appropriate treatment. Others are bothered by unacceptable levels of symptoms that severely impair their quality of life and represent a significant financial burden to themselves and to their healthcare providers. Recently updated guidelines from the International Consultation on Incontinence (ICI) and the European Association of Urology (EAU) take account of important new developments in the management of bladder problems in both primary and secondary care. However, local implementation of previous guidance has been variable, with many patients with OAB and other bladder problems failing to gain full benefit from current clinical and scientific understanding of these conditions. The recent expansion of the range of treatments available for OAB and stress urinary incontinence makes it especially important that physicians become aware of the differential diagnosis of these conditions - the questions they need to ask, and the investigations which will help determine the most appropriate course of action.
Guidelines for the management of continence and overactive bladder are generally available across Europe. For a majority of countries, these have been adopted by professional societies in either urology or gynaecology for local use. There has, however, been little monitoring of formal implementation of these guidelines and seldom any attempt to audit their operation. The state of continence care therefore remains largely unknown. This article reviews current guidelines and their status across Europe and examines what might be relevant from other disease areas to promote successful implementation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
