Abstract
PURPOSE To assess the effects of Serenoa repens in the treatment of men with lower urinary tract symptoms (LUTS) consistent with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS We performed a comprehensive search using multiple databases up to September 2022 with no language or publication status restrictions. We included parallel-group randomized controlled trials of participants with BPH who were treated with Serenoa repens or placebo/no treatment. We used standard Cochrane methods, including a GRADE assessment of the certainty of the evidence (CoE). RESULTS We included 27 studies involving a total of 4,656 participants. Serenoa repens results in little to no difference in urologic symptoms at short-term follow-up (International Prostate Symptom Score [IPSS]: mean difference [MD] -0.90, 95% confidence interval [CI] -1.74 to -0.07; I²=68%; 9 studies, 1,681 participants; high CoE). Serenoa repens results in little to no difference in the quality of life at short-term follow-up (high CoE). Serenoa repens probably results in little to no difference in adverse events (moderate CoE). Different phytotherapeutic agents that include Serenoa repens may result in little to no difference in urologic symptoms compared to placebo at short-term follow-up (IPSS: MD -2.41, 95% CI -4.54 to -0.29; I²=67%; 4 studies, 460 participants; low CoE). We are very uncertain about the effects of these agents on quality of life (very low CoE). These agents may result in little to no difference in the occurrence of adverse events (low CoE). CONCLUSIONS Serenoa repens alone provides little to no benefits for men with LUTS due to benign prostatic enlargement. There is more uncertainty about the role of Serenoa repens in combination with other phytotherapeutic agents.

Abstract
The popularity of natural products for the treatment of lower urinary tract symptoms (LUTS) differs considerably between countries. Here we discuss the clinical evidence for efficacy in two indications, male LUTS suggestive of benign prostatic hyperplasia and urinary tract infections, and the mechanistic evidence from experimental studies. Most evidence for male LUTS is based on extracts from saw palmetto berries, stinging nettle roots, and pumpkin seeds, whereas most evidence for urinary tract infection is available for European golden rod and combined preparations although this field appears more fragmented with regard to extract sources. Based on differences in sample collection and extraction, extracts from the same plants are likely to exhibit at least quantitative differences in potential active ingredients, which makes extrapolation of findings with one extract to those of others potentially difficult. While only limited information is available for most individual extracts, some extracts have been compared to placebo and/or active controls in adequately powered trials.

Abstract
The safety of Serenoa repens (SR)-containing products was evaluated conducting a retrospective worldwide analysis of pharmaco- and phytovigilance report forms of suspected adverse reactions (SARs) collected up to 31 January 2022. Multivariate logistic regression was performed to estimate the odds ratios (ORs) of serious SAR. A total of 1810 report forms were analysed; 92% of subjects were males, with a median age of 69 years; 44% of cases were defined as serious. Subjects exposed to dietary supplements had a higher risk of developing serious SARs (OR: 1.60 [95% CI: 1.20-2.15]), as subjects exposed to 2-5 (OR: 1. 83 [95% CI: 1.30-2.58]) or more than 5 (OR: 3.45 [95% CI: 2.36-5.06]) suspect/interacting products. The probability of experiencing serious SAR was higher for subjects exposed to concomitant products (OR: 1.55 [95% CI: 1.15-2.08]), to more than four active compounds (OR: 4.38 [95% CI: 3.21-5.99]) and to SR for more than 14 days (OR: 1.89 [95% CI: 1.10-3, 22]), and lower for subjects exposed to higher doses of SR (OR: of 0.34 [95% CI: 0.20-0.58]). This evidence improves awareness on safety of SR containing products, suggesting the need of a further update of periodic reviews by national and international regulatory agencies.

Overview of current pharmacotherapeutic options in benign prostatic hyperplasia. Expert Opin Pharmacother 2023; 24:1609-1622. [PMID: 37448198 DOI: 10.1080/14656566.2023.2237406] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 06/27/2023] [Accepted: 07/13/2023] [Indexed: 07/15/2023]
Abstract
INTRODUCTION Benign prostatic hyperplasia (BPH) represents the histological entity of prostate cell proliferation, which inflicts a gradually increasing obstruction of the bladder outlet and is accompanied by a progressing manifestation of lower urinary tract symptoms (LUTS). BPH management algorithm includes conservative measures, pharmaceutical agents, and surgical procedures. AREAS COVERED A comprehensive literature review was performed using PubMed, Scopus, and Google Scholar databases to identify publications written in English, analyzing BPH pharmaceutical treatment. The search was conducted from January 2000 to January 2023. Six main drug classes can be administered, either as monotherapy or in combination. Furthermore, the authors provide current direction of research on future medications, which focuses on a more etiological interference to the BPH pathophysiological mechanism. EXPERT OPINION The available medications represent an effective first-line step of BPH/LUTS therapy. Currently, the administration of BPH medications is tailored to patient/disease characteristics and entails long-time adherence to therapy. The emergence of new surgical modalities, which combine significantly lower morbidity compared to standard procedures and more durable effects than the available medications, seems to challenge the current treatment algorithm. More direct comparisons and the increasing experience with these surgical modalities will delineate the switch points between various therapy levels along the BPH management sequence.

Abstract
CONTEXT Lower urinary tract symptoms (LUTS) are common, often bothersome, and have multifactorial aetiology. OBJECTIVE To present a summary of the 2023 version of the European Association of Urology guidelines on the management of male LUTS. EVIDENCE ACQUISITION A structured literature search from 1966 to 2021 selected the articles with the highest certainty evidence. The Delphi technique consensus approach was used to develop the recommendations. EVIDENCE SYNTHESIS The assessment of men with LUTS should be practical. A careful medical history and physical examination are essential. Validated symptom scores, urine test, uroflowmetry, and postvoid urine residual, as well as frequency-volume charts for patients with nocturia or predominately storage symptoms should be used. Prostate-specific antigen should be ordered if a diagnosis of prostate cancer changes the treatment plan. Urodynamics should be performed for selected patients. Men with mild symptoms are candidates for watchful waiting. Behavioural modification should be offered to men with LUTS prior to, or concurrent with, treatment. The choice of medical treatment depends on the assessment findings, predominant type of symptoms, ability of the treatment to change the findings, and the expectations to be met in terms of the speed of onset, efficacy, side effects, and disease progression. Surgery is reserved for men with absolute indications, and for patients who fail or prefer not to receive medical therapy. Surgical management has been divided into five sections: resection, enucleation, vaporisation, and alternative ablative and nonablative techniques. The choice of surgical technique depends on patient's characteristics, expectations, and preferences; surgeon's expertise; and availability of modalities. CONCLUSIONS The guidelines provide an evidence-based approach for the management of male LUTS. PATIENT SUMMARY A clinical assessment should identify the cause(s) of symptoms and define the clinical profile and patient's expectations. The treatment should aim to ameliorate symptoms and reduce the risk of complications.

Abstract
BACKGROUND Benign prostatic hyperplasia (BPH) is a non-malignant enlargement of the prostate, which can lead to obstructive and irritative lower urinary tract symptoms (LUTS). The pharmacologic use of plants and herbs (phytotherapy) for the treatment of LUTS associated with BPH is common. The extract of the berry of the American saw palmetto or dwarf palm plant, Serenoa repens (SR), which is also known by its botanical name of Sabal serrulatum, is one of several phytotherapeutic agents available for the treatment of BPH. OBJECTIVES To assess the effects of Serenoa repens in the treatment of men with LUTS consistent with BPH. SEARCH METHODS We performed a comprehensive search of multiple databases (the Cochrane Library, MEDLINE, Embase, Scopus, Web of Science, and LILACS), trials registries, other sources of grey literature, and conference proceedings published up to 16 September 2022, with no restrictions on language or publication status. SELECTION CRITERIA We included randomized controlled trials of participants with BPH who were treated with Serenoa repens or placebo/no treatment. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion at each stage and undertook data extraction and risk of bias assessment and GRADE assessment of the certainty of the evidence. We considered review outcomes measured up to 12 months after randomization as short term, and beyond 12 months as long term. Our main outcomes included urologic symptom scores, quality of life, and adverse events. MAIN RESULTS For this update, we narrowed the review question to only comparisons with placebo. We included 27 studies (of which 9 were new) involving a total of 4656 participants, 19 studies comparing Serenoa repens with placebo, and 8 studies comparing Serenoa repens in combination with other phytotherapeutic agents versus placebo. Most studies included men aged > 50 (mean age range 52 to 68) with moderate urologic symptoms (International Prostate Symptom Score [IPSS] range 8 to 19). Ten studies were funded by the pharmaceutical industry; two studies were funded by government agencies; and the remaining studies did not specify funding sources. Serenoa repens versus placebo or no intervention Results for this comparison are based on predefined sensitivity analyses limited to studies at low risk of bias. Serenoa repens results in little to no difference in urologic symptoms at short-term follow-up (3 to 6 months; IPSS score range 0 to 35, higher scores indicate worse symptoms; mean difference (MD) -0.90, 95% confidence interval (CI) -1.74 to -0.07; I2 = 68%; 9 studies, 1681 participants; high-certainty evidence). Serenoa repens results in little to no difference in the quality of life at short-term follow-up (3 to 6 months; IPSS quality of life domain range 0 to 6, higher scores indicate worse quality of life; MD -0.20, 95% CI -0.40 to -0.00; I2 = 39%; 5 studies, 1001 participants; high-certainty evidence). Serenoa repens probably results in little to no difference in adverse events (1 to 17 months; risk ratio (RR) 1.01, 95% CI 0.77 to 1.31; I2 = 18%; 12 studies, 2399 participants; moderate-certainty evidence). Based on 164 cases per 1000 men in the placebo group, this corresponds to 2 more (38 fewer to 51 more) per 1000 men in the Serenoa repens group. Serenoa repens results in little to no difference in urologic symptoms at long-term follow-up (12 to 17 months, IPSS score, MD 0.07, 95% CI -0.75 to 0.88; I2 = 34%; 3 studies, 898 participants; high-certainty evidence). Serenoa repens results in little to no difference in quality of life at long-term follow-up (12 to 17 months, IPSS quality of life, MD -0.11, 95% CI -0.41 to 0.19; I2 = 65%; 3 studies, 882 participants; high-certainty evidence). There were no data on long-term adverse events for this comparison. Serenoa repens in combination with other phytotherapy versus placebo or no intervention Different phytotherapeutic agents that include Serenoa repens may result in little to no difference in urologic symptoms compared to placebo at short-term follow-up (12 to 24 weeks, IPSS score, MD -2.41, 95% CI -4.54 to -0.29; I2 = 67%; 4 studies, 460 participants; low-certainty evidence). We are very uncertain about the effects of these agents on quality of life (very low-certainty evidence). These agents may result in little to no difference in the occurrence of adverse events; however, the CIs included substantial benefits and harms (12 to 48 weeks, RR 0.91, 95% CI 0.58 to 1.41; I2 = 0%; 4 studies, 481 participants; low-certainty evidence). Based on 132 cases per 1000 men in the placebo group, this corresponds to 12 fewer (55 fewer to 54 more) per 1000 men in the combined phytotherapeutic agents with Serenoa repens group. AUTHORS' CONCLUSIONS Serenoa repens alone provides little to no benefits for men with lower urinary tract symptoms due to benign prostatic enlargement. There is more uncertainty about the role of Serenoa repens in combination with other phytotherapeutic agents.

Abstract
Benign prostatic hyperplasia (BPH) is a common male condition that impacts many men's quality of life by generating lower urinary tract symptoms (LUTS). In recent years, inflammation has become very common in the prostate, and BPH with inflammation has a higher International Prostate Symptom Score (IPSS) score and an enlarged prostate. Chronic inflammation leads to tissue damage and the release of pro-inflammatory cytokines, which play an important role in the pathogenesis of BPH. We will focus on current advancements in pro-inflammatory cytokines in BPH, as well as the future of pro-inflammatory cytokine research.

Abstract
OBJECTIVE The objective of this sub-analysis of the PERSAT study was to evaluate the efficacy of hexanic extract of S. Repens (HESr) and alpha-blockers (AB), at 6 months in patients with moderate to severe LUTS/BPH. METHODS The PERSAT observational study was conducted in France by general practitioners on patients with BPH with an IPSS≥12 score. The primary endpoint was the percentage of responders (decrease in total IPSS score ≥ 3) at 6 months. Improvement in quality of life (IPSS-QoL) as well as patient satisfaction were also measured. RESULTS Of the 759 patients in the study, 324 treated with HESr and 309 with AB were reviewed at 6 months, with no change in treatment during follow-up. Characteristics at inclusion were globally similar with a mean IPSS of 18.2±4.9. The response rates at 6 months (IPSS-total decrease ≥ 3) were 93.7% and 94.8% for patients treated with HESr and AB, with a mean decrease in IPSS score of 10.1±5.6 points, which reached 13.6 and 14.8 points respectively, in severe patients (IPSS>19), without major difference between groups. More than 95% of HESr or AB patients reported a significant overall improvement in their LUTS/BPH. The most frequently reported adverse events with AB were ejaculation disorders (4.9%) and hypotension (4.2%) and with HESr digestive disorders (1.5%). CONCLUSION This sub-analysis of the PERSAT cohort reported the clinical efficacy of HESr and AB as a first-line treatment in the management of moderate or severe LUTS/BPH patients.

De Nunzio C, Salonia A, Gacci M, Ficarra V. The Role of Combination Therapy with α-Blockers and Hexanic Extract of Serenoa repens in the Treatment of LUTS/BPH. J Clin Med 2022; 11:7169. [PMID: 36498751 PMCID: PMC9736252 DOI: 10.3390/jcm11237169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 11/17/2022] [Accepted: 12/01/2022] [Indexed: 12/12/2022] Open
Abstract
The hexanic extract of Serenoa repens (HESr) has been in use for decades as an effective, safe and well-tolerated therapy for relieving bothersome lower urinary tract symptoms (LUTS) associated with benign prostate hyperplasia (BPH). This manuscript gives an overview of HESr as monotherapy for LUTS/BPH treatment and focuses on the currently available literature investigating the possible clinical benefits of HESr combination therapy with α-blockers. Combination therapy of HESr with α-blockers has been gaining significant interest in recent years, as an increasing body of evidence shows the beneficial pharmacological effects that HESr treatment can add to standard first-line treatment with α-blockers. By reducing persistent Prostatic Inflammatory Status (PIS), commonly present in LUTS/BPH patients, HESr complements the relaxation of prostate smooth muscle induced by α-blockers, thus providing additional symptom relief. Data suggest that patients harbouring PIS and having a specific clinical profile might especially benefit from the combination therapy. Future therapeutic efforts may take advantage of more personalised strategies for LUTS/BPH management.

Permixon®, hexane-extracted Serenoa repens, inhibits human prostate and bladder smooth muscle contraction and exerts growth-related functions in human prostate stromal cells. Life Sci 2022; 308:120931. [PMID: 36084760 DOI: 10.1016/j.lfs.2022.120931] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 08/25/2022] [Accepted: 09/01/2022] [Indexed: 11/24/2022]
Abstract
AIMS Recently, the European Association of Urology recommended hexane-extracted fruit of Serenoa repens (HESr) in their guidelines on management of non-neurogenic male lower urinary tracts symptoms (LUTS). Despite previously lacking recommendations, Permixon® is the most investigated HESr in clinical trials, where it proved effective for male LUTS. In contrast, underlying mechanisms were rarely addressed and are only marginally understood. We therefore investigated effects of Permixon® on human prostate and detrusor smooth muscle contraction and on growth-related functions in prostate stromal cells. MAIN METHODS Permixon® capsules were dissolved using n-hexane. Contractions of human prostate and detrusor tissues were induced in organ bath. Proliferation (EdU assay), growth (colony formation), apoptosis and cell death (flow cytometry), viability (CCK-8) and actin organization (phalloidin staining) were studied in cultured human prostate stromal cells (WPMY-1). KEY FINDINGS Permixon® inhibited α1-adrenergic and thromboxane-induced contractions in prostate tissues, and methacholine-and thromboxane-induced contractions in detrusor tissues. Endothelin-1-induced contractions were not inhibited. Neurogenic contractions were inhibited in both tissues in a concentration-dependent manner. In WPMY-1 cells, Permixon® caused concentration-dependent breakdown of actin polymerization, inhibited colony formation, reduced cell viability, and proliferation, without showing cytotoxic or pro-apoptotic effects. SIGNIFICANCE Our results provide a novel basis that allows, for the first time, to fully explain the ubiquitous beneficial effects of HESr in clinical trials. HESr may inhibit at least neurogenic, α1-adrenergic and thromboxane-induced smooth muscle contraction in the prostate and detrusor, and in parallel, prostate stromal cell growth. Together, this may explain symptom improvements by Permixon® in previous clinical trials.

Abstract
OBJECTIVE to evaluate diverse scientific evidence on the effectiveness of complementary therapies in the control of lower urinary tract symptoms in the adult and aged male population. METHOD a systematic review developed according to the PRISMA checklist. The search was performed in the CINAHL, Embase, LILACS, PEDro, PubMed, Web of Science and Google Scholar databases. RESULTS a total of 585 records were identified and 12 clinical trials were selected that met the inclusion criteria. The outcomes considered by the studies for analyzing effectiveness of the complementary therapies were validated questionnaires to assess the severity of the lower urinary tract symptoms (sensation of incomplete bladder emptying, frequent urination, intermittent flow, weak flow, pain or difficulty urinating, nocturia and urgency) and urodynamics parameters. The studies analyzed the complementary phytotherapy (n=8) and electroacupuncture (n=4) therapies. Six studies related to phytotherapy showed statistical significance. Electroacupuncture showed a significant improvement in the symptoms in two studies. CONCLUSION pytotherapy was effective to control the simptoms related to frequency, urgency, nocturia, incomplete emptying, intermittence, weak flow and effort to initiate urination. To confirm the effectiveness of electroacupuncture, research studies with well-designed methodologies will also be necessary to resolve the divergences between the studies of this review.

Abstract
The objective of this subset analysis was to evaluate and compare the efficacy and tolerability of two combination treatments for men with moderate-to-severe lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH). Data were from a real-world, open-label, prospective, and multicenter study performed in outpatient urology clinics. Men with moderate-to-severe LUTS/BPH received 6-month treatment with tamsulosin (TAM) in combination with either the hexanic extract of S. repens (HESr) or a 5-alpha-reductase inhibitor (5ARI). Changes in urinary symptoms and quality of life were measured using the IPSS and BII questionnaires, respectively. Treatment tolerability was assessed by recording adverse effects (AEs). Patients in the two study groups were matched using iterative and propensity score matching approaches. After iterative matching, data were available from 136 patients (n = 68 treated with TAM + 5ARI, n = 68 with TAM + HESr). After 6 months of treatment, mean (SD) IPSS total score improved by 7.7 (6.3) and 6.7 (5.0) points in the TAM + 5ARI and TAM + HESr groups, respectively (p = 0.272); mean BII total scores improved by 3.1 (2.9) and 2.9 (2.4) points (p = 0.751), respectively. AEs were reported by 26.5% and 10.3% of patients in the same groups, mostly affecting sexual function (p < 0.027). When used in a real-world setting to treat patients with moderate-severe LUTS/BPH, 6-month treatment with TAM + HESr was as effective as TAM + 5ARI, but with better tolerability.

Abstract
The hexanic extract (HE) of Serenoa repens (Permixon®) is indicated for the symptomatic treatment of benign prostatic hyperplasia (BPH). The drug is the n-hexane lipidosterolic extract of the American dwarf palm tree (also known as saw palmetto). The anti-inflammatory activity of HE S.repens has been demonstrated in vitro, in vivo and in men with prostatic inflammation. In randomized clinical trials, the efficacy of HE S. repens was similar to that of an α-blocker in terms of improving voiding and storage symptoms, increasing urinary flow rate and reducing prostate volume in men with BPH. HE S. repens was also as effective as 5α-reductase inhibitors and/or α-blockers at improving lower urinary tract symptoms (LUTS) and quality of life (QOL) in real-world observational studies. HE S. repens was generally well tolerated, with a lesser impact on male sexual function compared with other available therapies. Thus, HE S. repens is a useful option for the treatment of symptomatic BPH. BPH (enlargement of the prostate gland) compresses the urethra, leading to uncomfortable LUTS such as difficulty starting a urine stream, weak flow, incomplete bladder emptying, frequent urination, urgency, and waking at night to urinate. To avoid side effects often associated with other available treatments such as 5α-reductase inhibitors and α-blockers, plant extracts like HE Serenoa repens (Permixon®) are commonly used to treat the symptoms of BPH. HE S. repens is derived from a small palm tree native to America and has been shown to have anti-inflammatory effects in prostate inflammation. In clinical studies, HE S. repens was as effective as an α-blocker at improving urinary symptoms, increasing urinary flow rate and reducing prostate volume in men with BPH. In real-world studies, HE S. repens was as effective as 5α-reductase inhibitors and/or α-blockers at improving LUTS and QOL. European guidelines recommend HE S. repens as a treatment option for men with LUTS who want to avoid any potential side effects, especially those related to sexual function. HE S. repens was generally well tolerated, and is a useful option for the treatment of symptomatic BPH.

Abstract
We investigated changes in symptoms and quality of life (QoL) in men with moderate-to-severe lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH) receiving the hexanic extract of Serenoa repens (HESr) and compared results with a matched group on watchful waiting (WW). Data was from a real-world, open-label, prospective, multicenter study. This sub-group analysis included patients with moderate-to-severe symptoms receiving either the HESr 320 mg/daily for six months (HESr) or who remained untreated for LUTS/BPH (WW). Changes in urinary symptoms and QoL were measured by IPSS and BII questionnaires. Two statistical approaches (iterative matching and propensity score pairing) were used to maximize between-group comparability at baseline. Tolerability was assessed in the HESr group. After iterative matching, data for analysis was available for 783 patients (102 WW, 681 HESr). IPSS scores improved by a mean (SD) of 3.8 (4.4) points in the HESr group and by 2.2 (4.5) points in the WW group (p = 0.002). Changes in BII score were 1.8 (2.4) points and 1.0 (2.2) points, respectively (p < 0.001). Three patients (0.9%) treated with the HESr reported mild adverse effects. Moderate-severe LUTS/BPH patients treated for six months with the HESr showed greater improvements in symptoms and QoL than matched patients on WW, with a very low rate of adverse effects.

Abstract
BACKGROUND Serenoa repens (SR) is a plant used to treat benign prostatic hyperplasia and prostatitis. We know that SR act as a 5α-reductase inhibitor, moreover, several studies have proved that SR has anti-inflammatory and antioxidant properties. There is some belief among patients that SR may negatively impact male sexual function. Such belief is circulating in non-medical social networks and is perhaps maintained by patients as a result of incorrect web surfing. However, it is also possible that SR may exert a "nocebo" effect thus negatively impacting on the general well-being of patients. OBJECTIVE The aim of this study is to investigate whether SR is causing negative effects on male sexual function. METHODS To ascertain the effect of SR on male sexual function, we conducted a systematic review and meta-analysis, by performing an electronic database search in accordance with the PRISMA guidelines. RESULTS Out of 20 included papers, 8 papers reported comparisons of SR with placebo, and 7 studies reported comparisons of SR with tamsulosin. The standardized mean difference of changes from baseline scores of sexual function was not significantly different between SR and placebo (SMD: 0.43, 95% CI: 0.18 to 1.05; I^2 = 95%). Similarly, no significant mean differences in the Male Sexual Function-4 (MSF-4) test scores were found between SR and tamsulosin (SMD: -0.31, 95% CI: -0.82 to 0.19; I^2 = 90%). CONCLUSIONS We found no statistically significant differences between negative effects on sexual function in patients treated with SR compared to patients who received placebo. The results of our meta-analysis are similar to those of other systematic reviews. Studies are warranted to ascertain whether any such effects might occur as a result of a nocebo effect.

Abstract
Saw palmetto extract (SPE) has been widely used as a therapeutic remedy for urinary dysfunction in western countries. Furthermore, as an herb drug, it can be used as an alternative therapy for benign prostatic hyperplasia (BPH) due to its safety and minimum adverse effects. Reportedly, SPE improves the urinary symptoms, which mainly depend on anti-androgenic effects and effects on autonomic receptors in the lower urinary tract. However, the mechanisms of action responsible for the therapeutic roles of SPE have not been fully elucidated. Relevant studies indicate that SPE has some positive effects on the treatment of urological diseases in animals, and clinical trials are ongoing. In this review, we summarize the pharmacological properties and discuss the possible therapeutic mechanisms of SPE in urological diseases, including anti-androgenic effects, effects on autonomic receptors in the lower urinary tract, anti-inflammatory activity, anti-proliferative and pro-apoptotic effects, and highlight a potential therapeutic approach in the clinical treatment of patients with BPH, prostate cancer, chronic prostatitis (CP) and erectile dysfunction (ED).

Efficacy and tolerability of the hexanic extract of Serenoa repens compared to tamsulosin in moderate-severe LUTS-BPH patients. Sci Rep 2021; 11:19401.

Abstract
In a subset analysis of data from a 6-month, multicenter, non-interventional study, we compared change in symptoms and quality of life (QoL), and treatment tolerability, in men with moderate to severe lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH) receiving tamsulosin (TAM, 0.4 mg/day) or the hexanic extract of Serenoa repens (HESr, 320 mg/day) as monotherapy. Symptoms and QoL were assessed using the IPSS and BII questionnaires, respectively. Patients in the treatment groups were matched using two statistical approaches (iterative and propensity score matching). Within the iterative matching approach, data was available from a total of 737 patients (353 TAM, 384 HESr). After 6 months, IPSS scores improved by a mean (SD) of 5.0 (4.3) points in the TAM group and 4.5 (4.7) points in the HESr group (p = 0.117, not significant). Improvements in QoL were equivalent in the two groups. TAM patients reported significantly more adverse effects than HESr patients (14.7% vs 2.1%; p < 0.001), particularly ejaculation dysfunction and orthostatic hypotension. These results show that HESr is a valid treatment option for men with moderate/severe LUTS/BPH; improvements in urinary symptoms and QoL were similar to those observed for tamsulosin, but with considerably fewer adverse effects.

Abstract
PURPOSE To assess the effects of Serenoa repens alone or in combination with other phytotherapy compared to placebo in men with LUTS due to benign prostatic enlargement. MATERIALS AND METHODS Following a registered protocol (CRD42021226655), we searched (December 2020) MEDLINE, CENTRAL, Embase, ClinicalTrials.gov, WHO-ICTRP trials platform and other sources with no restrictions on language, publication date or status. We included randomized controlled trials, and we critically appraised them using the Cochrane Tool for Risk of Bias Assessment (RoB 2). We conducted random-effects meta-analysis when appropriate. The primary outcomes included urinary symptoms score, quality of life, and adverse events. The certainty of the evidence was rated using GRADE. RESULTS We included 27 trials with 4,853 participants. S. repens results in little to no difference in urinary symptoms, quality of life, and adverse events at short- and long-term follow-up. S. repens combined with other phytotherapy may slightly reduce urinary symptoms at short-term follow-up, but the results are uncertain. The results on quality of life and adverse events are also very uncertain. CONCLUSIONS S. repens alone may result in no clinical benefits for men with LUTS. There is greater uncertainty in the effects of S. repens in combination with other phytotherapy.

Abstract
Benign prostatic hyperplasia (BPH) is an age-related chronic disorder, characterized by the hyperproliferation of prostatic epithelial and stromal cells, which drives prostate enlargement. Since BPH aetiology and progression have been associated with the persistence of an inflammatory stimulus, induced both by Nuclear Factor-kappa B (NF-κB) activation and reactive oxygen species (ROS) production, the inhibition of these pathways could result in a good tool for its clinical treatment. This study aimed to evaluate the antioxidant and anti-inflammatory activity of a combined formulation of Serenoa repens and Urtica dioica (SR/UD) in an in vitro human model of BPH. The results confirmed both the antioxidant and the anti-inflammatory effects of SR/UD. In fact, SR/UD simultaneously reduced ROS production, NF-κB translocation inside the nucleus, and, consequently, interleukin 6 (IL-6) and interleukin 8 (IL-8) production. Furthermore, the effect of SR/UD was also tested in a human androgen-independent prostate cell model, PC3. SR/UD did not show any significant antioxidant and anti-inflammatory effect, but was able to reduce NF-κB translocation. Taken together, these results suggested a promising role of SR/UD in BPH and BPH-linked disorder prevention.

Abstract
To investigate whether tamsulosin (TAM) and the hexanic extract of Serenoa repens (HESr) are more effective in combination than as monotherapy in men with moderate-to-severe lower urinary tract symptoms associated with benign prostatic hyperplasia (LUTS/BPH). Subset analysis of data from a 6-month, multicenter observational study. Patients received either tamsulosin (0.4 mg/day) or HESr (320 mg/day) alone or in combination. Primary endpoints were change in symptoms and quality of life. Tolerability was also assessed. Seven hundred and nine patients were available for intention to treat (ITT) analysis, 263 treated with tamsulosin, 262 with HESr, and 184 with TAM + HESr. After 6 months, International Prostate Symptom Score (IPSS) scores improved by a mean (standard deviation) of 7.2 (5.0) points in the TAM + HESr group compared to 5.7 (4.3) points with TAM alone and 5.4 (4.6) points with HESr (p < 0.001). Quality of life showed greatest improvement with combination therapy (p < 0.02). Adverse effects were reported by 1.9% of patients receiving HESr, 13.3% receiving TAM, and 12.0% receiving TAM + HESr (p < 0.001). In men with moderate/severe LUTS/BPH, combination treatment with TAM + HESr produced more effective symptom relief and greater improvement in quality of life than with either treatment alone, with acceptable tolerability.

Abstract
PURPOSE The objective of the PERSAT study was to evaluate first-line treatment of BPH-associated LUTS in real-life conditions. METHODS This prospective observational study was conducted in France by general practitioners (GP) on patients with moderate to severe LUTS (IPSS ≥12). GPs freely decided to prescribe either an alpha-blocker (AB) or phytotherapeutic treatment (PT). The main criterion was the percentage of responding patients (decrease in total IPSS score ≥3) at 6 months. RESULTS Of the 849 patients included, 759 were analysed (381 treated with AB and 378 with PT); 718 were followed up at 6 months, 90% of which had no treatment modification. Their inclusion characteristics were similar between the AB and PT groups (mean IPSS: 18.6±4.5 and 17.8±4.1, respectively). Treatment response rates at 6 months were 94.2% [91.2%; 96.4%] in AB and 92.5% [89.2%; 95.1%] in PT. The IPSS decreased by 10.0±5.6 points, with no difference between groups. The proportion of patients bothered by their LUTS (IPSS-QoL ≥4) evolved from 88.5% to 6.5% at 6 months. The improvement of LUTS was perceived by more than 94% of patients (PGI-I) and doctors (CGI-I), 93% of patients were satisfied with the treatment at 6 months, regardless of the treatment initiated. The most reported adverse reactions were ejaculation disorder (3.9% for AB and 0.9% for PT). CONCLUSION PERSAT confirms in current practice the effectiveness of AB and PT treatments, recommended as first-line treatment in LUTS/BPH. LEVEL OF PROOF 3.

The Clinical Impact of Hexanic Extract of Serenoa repens in Men with Prostatic Inflammation: A Post Hoc Analysis of a Randomized Biopsy Study. J Clin Med 2020; 9:jcm9040957.

Abstract
A randomized biopsy study showed that hexanic Serenoa repens (HESr) treatment resulted in prostatic inflammation reduction. This post-hoc analysis evaluated the clinical impact of HESr and investigated correlations between baseline parameters and treatment response. Patients were randomized to receive HESr 320mg/day for six months or no therapy. Assessment included International Prostate Symptoms Score (IPSS), prostate volume (PV), and maximum flow rate (Qmax). Baseline characteristics were recorded, including body mass index (BMI) and metabolic syndrome (MetS) components. In patients under α1-adrenoceptor antagonists (α1-blockers), the addition of HESr resulted in statistically significant IPSS improvement after 6 months (p = 0.006). IPSS remained stable in patients under a1-blockers only (p = 0.346). Patients treated only with HESr reported a significant IPSS amelioration (p = 0.001). In the control group of naïve patients, no significant IPSS change was detected (p = 0.298). Baseline PV showed fair correlation (r = −0.20) with inflammation reduction in the HESr patients. BMI (r = 0.40), diabetes mellitus (r = 0.40), and PV (r = 0.23) showed fair correlation with Qmax increase but without reaching statistical significance. MetS (p = 0.06) was an influent biomarker for Qmax improvement. Treatment with HESr (as monotherapy or add-on therapy to a-blockers) may improve urinary symptoms in terms of IPSS in patients with prostatic inflammation.

Abstract
Background Benign prostatic hyperplasia (BPH) etiology remains poorly understood, but chronic low‐grade inflammation plays a role. Pulsed electromagnetic field therapy (PEMF) (1‐50 Hz) is effective in reducing tissue inflammation. Objectives We designed a pilot study to evaluate the effects of PEMF on prostate volume (PV) in BPH. Materials and Methods This is a prospective interventional trial on 27 naive patients with BPH and lower urinary tract symptoms (LUTS). At baseline (V0), all patients had blood tests, transrectal ultrasound, and questionnaires (IPSS, IIEF‐15) and received a perineal PEMF device (Magcell®Microcirc, Physiomed Elektromedizin). PEMF was delivered on perineal area 5 minutes twice daily for 28 days, then (V1) all baseline evaluations were repeated. Afterward, nine patients continued therapy for 3 more months (PT group) and 15 discontinued (FU group). A 4‐month evaluation (V2) was performed in both groups. Results A reduction was observed both at V1 and at V2 in PV: PVV0 44.5 mL (38.0;61.6) vs PVV1 42.1 mL (33.7;61.5, P = .039) vs PVV2 41.7mL (32.7;62.8, P = .045). IPSS was reduced both at V1 and at V2: IPSSV0 11 (5.7;23.2) vs IPSSV1 10 (6;16, P = .045) vs IPSSV2 9 (6;14, P = .015). Baseline IPSS was related to IPSS reduction both at V1 (rs = 0.313;P = .003) and at V2 (rs = 0.664;P < .001). PV reduction in patients without metabolic syndrome (ΔPVV1nMetS −4.7 mL, 95%CI −7.3;‐2.0) was greater than in affected patients (ΔPVV1MetS 1.7 mL, 95%CI −2.69;6.1)(P = .017, Relative RiskMetS = 6). No changes were found in gonadal hormones or sexual function. Discussion PEMF was able to reduce PV after 28 days of therapy. Symptoms improved in a short time, with high compliance and no effects on hormonal and sexual function or any side effects. Patients with moderate‐severe LUTS and without MetS seem to benefit more from this treatment. Conclusion PEMF reduces PV and improves LUTS in a relative short time, in BPH patients. These benefits seem greater in those patients with moderate‐severe LUTS but without MetS.

Abstract
Studies reported that Serenoa repens was effective in relieving lower urinary tract symptoms (LUTS). This article carried out a systematic review and meta-analysis to compare Serenoa repens with tamsulosin in the treatment of benign prostatic hyperplasia (BPH) after at least 6-month treatment cycle. Four studies involving 1,080 patients (543 in the Serenoa repens group and 537 in the tamsulosin group) were included in the meta-analysis. The results were as follows: compared with tamsulosin, Serenoa repens had a same effect in treating BPH in terms of International Prostate Symptom Score (IPSS) (mean difference [MD] 0.63, 95% confidence interval [CI] [-0.33, 1.59], p = 0.20), quality of life (QoL) (MD 1.51, 95% CI [-1.51, 4.52], p = 0.33), maximum flow rate (Qmax) (MD 0.27, 95% CI [-0.15, 0.68], p = 0.21), postvoid residual volume (PVR) (MD -4.23, 95% CI [-22.97, 14.44], p = 0.65), prostate-specific antigen (PSA) (MD 0.46, 95% CI [-0.06, 0.97], p = 0.08) with the exception of prostate volume (PV) (MD -0.29, 95% CI [-0.41, -0.17], p < 0.00001). For side effects, Serenoa repens was well tolerated compared with tamsulosin especially in ejaculation disorders (odds ratio [OR] = 12.56, 95% CI [3.83, 41.18], p < 0.0001) and decreased libido (OR = 5.40; 95% CI [1.17, 24.87]; p = 0.03). This study indicated that Serenoa repens had the same effect in treating BPH compared with tamsulosin in terms of IPSS, QoL, and PVR after at least 6-month treatment cycle, however, the latter had a greater improvement in PV compared with the former. And Serenoa repens did not increase the risk of adverse events especially with respect to ejaculation disorders and libido decrease.

Inflammation is a target of medical treatment for lower urinary tract symptoms associated with benign prostatic hyperplasia. World J Urol 2020; 38:2771-2779. [PMID: 32060633 PMCID: PMC7644532 DOI: 10.1007/s00345-020-03106-1] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Accepted: 01/23/2020] [Indexed: 12/17/2022] Open
Abstract
Purpose To review the role of a persistent prostatic inflammatory status (PIS) in the development and progression of benign prostatic hyperplasia (BPH) associated with lower urinary tract symptoms (LUTS) and which medical therapies approved for LUTS/BPH may reduce persistent PIS. Methods Literature search in PubMed up to July 2019. Results The cause of histologically defined persistent PIS or chronic prostatic inflammation is multifactorial. It is evident in many men with LUTS/BPH, particularly in older men and in men with a large prostate volume or more severe (storage) LUTS. Additionally, persistent PIS is associated with an increased risk of acute urinary retention and symptom worsening. Of medical therapies approved for LUTS/BPH, the current evidence for a reduction of persistent PIS is greatest for the hexanic extract of Serenoa repens (HESr). This treatment relieves LUTS to the same extent as α1-adrenoceptor antagonists and short-term 5α-reductase inhibitors. Limited evidence is available on the effect of other mainstream LUTS/BPH treatments on persistent PIS. Conclusions Persistent PIS plays a central role in both the development and progression of LUTS/BPH. In men with LUTS/BPH who have a high chance of harbouring persistent PIS, HESr will not only improve LUTS, but also reduce (underlying) inflammation. Well-designed clinical studies, with a good level of evidence, are required to better evaluate the impact of BPH/LUTS medical therapies on persistent PIS.

Eur Urol Focus 2020; 7:420-431. [PMID: 31952967 DOI: 10.1016/j.euf.2020.01.002] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Revised: 12/26/2019] [Accepted: 01/07/2020] [Indexed: 11/29/2022]
Abstract
CONTEXT International guidelines do not make any specific recommendations on Serenoa repens (SeR) for the treatment of male lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement (BPE), due to product heterogeneity and methodological limitations of the published trials and meta-analyses. OBJECTIVE We aimed to compare the clinical efficacy of hexanic extract of SeR (HESr) versus non-HESr (nHESr) versus placebo versus alpha-blockers (ABs) in patients affected by LUTS secondary to BPE through a network meta-analysis method. EVIDENCE ACQUISITION The search was conducted until December 31, 2018 using Medline, Scopus, and Web of Science databases without restriction. We included randomized controlled trials (RCTs) with at least one comparison between SeR, ABs, or placebo for the treatment of LUTS/BPE. Outcomes of the study were the mean change in the International Prostate Symptom Score (IPSS) and peak flow (PF). This systematic review has been registered on PROSPERO (CRD42018084360). EVIDENCE SYNTHESIS In total, 2115 articles were identified. After the global assessment, 22 RCTs matched with the inclusion criteria, including 8564 patients. For IPSS, the mean efficacies against placebo were +0.48 and -1.69 for HESr and nHESr, respectively, at 3 mo; 0.59 for nHESr at 6 mo; and -1.31 and -3.30 for nHESr and HESr, respectively, at 12 mo. For PF, the mean efficacies against placebo were +0.53 and +2.82 for HESr and nHESr, respectively, at 3 mo; +1.85 for nHESr at 6 mo; and +4.05 and +5.52 for HESr and nHESr, respectively, at 12 mo. Based on the surface under the cumulative ranking curve rankograms, terazosin showed the highest score (99.6%), while alfuzosin, tamsulosin, silodosin, HESr, and nHESr showed scores of 53.7%, 42.3%, 68.5%, 36.7%, and 47.3%, respectively. CONCLUSIONS In this network meta-analysis, we demonstrated that SeR did not show clinically meaningful improvement in LUTS and PF. PATIENT SUMMARY In the present study, we found no clinically meaningful improvement of Serenoa repens for the treatment of lower urinary tract symptoms/benign prostatic enlargement. The analysis showed that the benefit over placebo was minimal and may not justify its clinical use before higher level of evidence will be available.

Abstract
Benign prostatic hyperplasia (BPH) is a noncancerous growth of the prostate. BPH commonly occurs in elderly men. Lower urinary tract symptoms (LUTS) secondary to BPH (LUTS/BPH) have significant impacts on their health. Saw palmetto (Serenoa repens) extract (SPE) has been evaluated for its effectiveness in improvement of LUTS/BPH at preclinical and clinical levels. Potential mechanisms of actions include anti-androgenic, pro-apoptotic, and anti-inflammatory effects. However, SPE efficacy was inconsistent, at least partly due to a lack of a standardized SPE formula. A hexane extract (free fatty acids, > 80%) provided more consistent results. Free fatty acids (lauric acid) were effective in inhibition of 5α-reductase, and phytosterol (β-sitosterol) reduced prostatic inflammation. Multiple actions derived from different constituents may contribute to SPE efficacy. Evaluation of the clinical relevance of these bioactive components is required for standardization of SPE, thereby enabling consistent efficacy and recommendations for the use in the prevention and treatment of BPH.

Abstract
OBJECTIVE To compare the efficacy and safety of oral supplementation with Serenoa repens (SR) and bovine colostrum (BC) plus tamsulosin (TAM) versus TAM alone over 12 months in men suffering from lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). METHODS Between February 2018 and February 2019, men with symptomatic BPH (IPSS ≥10) were prospectively recruited. This prospective, open-label, 12-month study included two different protocols: (1) group A, SR 320 mg/day + BC 30 mg/day + TAM 0.4 mg/day, and (2) group B, TAM 0.4 mg/day only. RESULTS Overall, 148 patients entered the study, 76 in group A and 72 in group B. At 12 months, the total IPSS had decreased by 5.5 with TAM + SR + BC and by 5.1 with TAM only (p = 0.21). However, when the total IPSS was divided into storage and voiding subscores, at 6 months the storage symptoms had improved significantly more with TAM + SR + BC (-1.6 vs. -0.9 with TAM only, p = 0.02), with the benefit persisting also at the 1-year evaluation (-1.8 vs. -0.8, p = 0.02). Moreover, the improvement in LUTS-related quality of life (QoL) was significantly different between the groups, with a mean decrease in IPSS QoL subscore of -2.5 ± 0.2 for TAM + SR + BC versus -1.8 ± 0.3 for TAM at 6 months (p = 0.04), and of -2.9 ± 0.4 for TAM + SR + BC versus -2.1 ± 0.4 for TAM at 12 months (p = 0.04). Conversely, no significant differences were found in maximal urinary flow rate (p = 0.38), postvoid residual volume (p = 0.12), prostate-specific antigen (p = 0.41), and prostate volume (p = 0.16). CONCLUSION Combination treatment with SR and BC plus TAM was shown to be more effective than treatment with TAM only in improving IPSS storage and QoL subscores in BPH patients after 6 months and up to 12 months of treatment.

Abstract
BACKGROUND Benign prostate syndrome is frequently associated with sexual dysfunction. The therapeutic options discussed in the S2e guideline may be able to improve existing sexual dysfunctions but can also worsen disorders or even trigger new ones. OBJECTIVES What are the effects of therapeutic options as described in the S2e guideline on sexual function? METHODS By selective literature search related to benign prostate syndrome and sexual dysfunction adverse effects of drugs mentioned in the S2e guideline have been evaluated. RESULTS Serenoa repens extracts do not have adverse effects on sexual function; this is also true for muscarine receptor antagonists. 5α-Reductase inhibitors frequently worsen erectile function, libido and ejaculation; selective α1-blockers have an adverse effect on ejaculation. Phosphodiesterase (PDE)-5 inhibitors can improve sexual function. A combination of α1-blockers and 5α-reductase inhibitors worsens sexual functions significantly. CONCLUSIONS A suitable therapy for benign prostate syndrome should be chosen jointly by the patient and the treating physician and should be adapted to personal needs. Effects on sexual functions have to be taken into consideration when choosing a therapy.

Abstract
Male lower urinary tract symptoms are frequently due to benign prostatic enlargement. Medical therapy is strongly recommended in patients with moderate to severe symptoms. Lower urinary tract symptoms may require a different medical approach using drugs with different mechanisms of action. Alpha-1 blockers, muscarinic receptor antagonists and phosphodiesterase type 5 inhibitors are the most frequently used drugs. 5-Alpha reductase inhibitors are commonly prescribed to reduce prostate volume and to prevent benign prostatic hyperplasia progression. Currently, medical treatment of lower urinary tract symptoms suggestive of benign prostatic enlargement can be tailored according to different symptom characteristics and severity, and to different patient comorbidities and preferences. For this reason, the decision-making process should be based on an accurate patient counselling with detailed clarification of potential benefits and, above all, potential side effects of different drugs. This non-systematic review of the literature presents an update of the current options for medical treatment of lower urinary tract symptoms suggestive of benign prostatic enlargement, helping urologists in the decision-making and counselling process.

Abstract
The class of lipophilic compounds coming from vegetal source represents a perspective in the adjuvant treatment of several human diseases, despite their poor bioavailability in humans. These compounds are generally soluble in fats and poorly soluble in water. The major reason for the poor bioavailability of lipophilic natural compounds after oral uptake in humans is related to their reduced solubility in enteric water-based fluids, leading to an ineffective contact with absorbing epithelium. The main goal to ensure efficacy of such compounds is then creating technological conditions to deliver them into the first enteric tract as hydro-dispersible forms to maximize epithelial absorption. The present work describes and characterizes a new technological matrix (Lipomatrix, Labomar Research, Istrana, TV, Italy) based on a molten fats core in which Ascorbyl Palmitate is embedded, able to deliver lipophilic compounds in a well-dispersed and emulsified form once exposed to duodenal fluids. Authors describe and quantify Lipomatrix delivery of Serenoa repens oil through an innovative in vitro model of human gastro-enteric digestion, reporting results of its improved bioaccessibility, enteric absorption and efficacy compared with not formulated Serenoa repens oil-containing commercial products using in vitro models of human intestine and prostatic tissue.

Abstract
Phytosterols are one of the bioactive components responsible for the beneficial effects of Serenoa repens in Benign Prostate Hyperplasia. The aim of this study was to verify the actual variability of the phytosterols content in supplements containing serenoa, in order to provide useful elements to check the effectiveness of these preparations. The amount of campesterol, stigmasterol and β-sitosterol were determined by gas-chromatography in commercial raw materials and supplements containing serenoa in association or not with other botanicals. The experimental data were used to calculate amounts of phytosterols for recommended daily dose. The overall results of this study show an extreme variability in the content and also in the amounts per daily dose of phytosterols of the examined supplements (both mono/multi components). These data confirm that the characterization of serenoa based supplements is insufficient to ensure comparable effects between different products.

Abstract
BACKGROUND The purpose of this narrative review is to evaluate the role of prostatic inflammation as a treatment target for lower urinary tract symptoms (LUTS) due to benign prostatic obstruction (BPO) and provide an update on the available therapies. METHODS An extensive literature search was conducted for studies on established and investigational treatments with anti-inflammatory mechanism of action that has been assessed for the management of male LUTS due to BPO. RESULTS Data on phosphodiesterase 5 inhibitors, nonsteroidal anti-inflammatory drugs, vitamin D3 receptor analogs, phytotherapy, statins, and lifestyle changes have been reviewed and analyzed. Preclinical evidence has shown the anti-inflammatory effect of these treatments on prostate. However, there is a wide variation in the degree of mature of each therapy. In addition, there are significant differences between the studies in terms of design, number of patients, and duration of follow-up. CONCLUSIONS Several drugs classes have been investigated for their impact on prostatic inflammation and improvement of male LUTS. The reviewed data support the rationale for use of agents that may alter and improve the inflammatory environment in the prostate in men with LUTS, but further high-quality long-term studies are required for the exact positioning of the new drugs in daily practice.

Abstract
OBJECTIVE To compare in a randomised, open-label, non-inferiority clinical study, the efficacy and tolerability of Serenoa repens (SeR) + selenium (Se) + lycopene (Ly) (SeR-Se-Ly) therapy vs tadalafil 5 mg in men with lower urinary tract symptoms (LUTS). PATIENTS AND METHODS From May 2015 to January 2017, 427 patients were enrolled in 21 different centres (International Standard Randomised Controlled Trial Number Register [ISRCTN] 73316039). Inclusion criteria included: age between 50 and 80 years, International Prostate Symptom Score (IPSS) ≥12, maximum urinary flow rate (Qmax ) ≤ 15 mL/s, and post-void residual (PVR) <100 mL. Patients were randomised into two groups in a 2:1 ratio: Group A (SeR-Se-Ly, 1 tablet daily for 6 months) and Group B (tadalafil 5 mg, 1 tablet daily for 6 months). The primary endpoint of the study was the non-inferior variation in the IPSS and Qmax in Group A vs Group B after 6 months of treatment. RESULTS In all, 404 patients completed the full protocol. When comparing both therapies, Group A was statistically not inferior to Group B considering the median change in IPSS (-3.0 vs -3.0; P < 0.01), IPSS quality of life (-2.0 vs -2.0; P < 0.05), and Qmax (2.0 vs 2.0 mL/s; P < 0.01). We found statistically significant differences in the increase of at least 3 points in Qmax (38.2% vs 28.1%; P = 0.04) and of at least 30% of Qmax (39.2% vs 27.3%; P < 0.01) in Group A compared to Group B. The percentage of patients with an increase of at least 3 points in the IPSS and a decrease of at least 25% of the IPSS was not statistically different between the two groups. For adverse events, four patients in Group A (1.44%) and 10 in Group B (7.81%) (P < 0.05) reported side-effects. CONCLUSION We have shown that treatment with SeR-Se-Ly was not inferior to tadalafil 5 mg for improving IPSS and Qmax in men with LUTS.
