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 method ological limitations of the published trials and meta-analyses .
OBJECTIVE We aim ed 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 .
Effects of hexanic extract of serenoa repens (permixon® 160 mg) on inflammation biomarkers in the treatment of lower urinary tract symptoms related to benign prostatic hyperplasia
Background Chronic prostatic inflammation ( CPI ) could be a cause of symptomatic or complicated benign prostatic hyperplasia ( BPH ) . In previous in vitro and in vivo studies , Hexanic Extract of Serenoa repens ( HESr ) namely Permixon ® has demonstrated potent anti‐inflammatory properties . With the aim to provide new insight onto HESr anti‐inflammatory properties in human we explore its effect on CPI biomarkers in men with lower urinary tract symptoms ( LUTS ) related to BPH using a non‐invasive method and investigate links between biomarkers and clinical symptoms . Methods An international , r and omized , double‐blind , parallel‐group , tamsulosin‐controlled study was carried out in 206 men with BPH‐related LUTS . Patients received oral daily HESr 320 mg or tamsulosin 0.4 mg during 3 months . The first urine stream after digital rectal examination ( DRE ) was collected at Day 1 and Day 90 and mRNA was extracted from prostatic epithelial cells desquaming in the lumen of the gl and s and seminal plasma fluid after DRE . mRNA quantification of the 29 most significant published inflammation markers in BPH and protein detection in urine was performed . Results At D90 , a decrease in mean gene expression was observed for 65.4 % of the markers detected in the HESr group versus 46.2 % in the tamsulosin group . In the 15 most frequently expressed genes , this difference was higher ( 80 % vs. 33 % respectively ) . Three proteins ( MCP‐1/CCL2 , IP‐10/CXCL10 , and MIF ) were detected . At D90 , a decrease in the number of patients who expressed MCP‐1/CCL2 and IP‐10/CXCL10 was observed only in the HESr group . Moreover , MIF expression was significantly reduced by HESr compared with tamsulosin ( P = 0.007 ) . Finally , in contrast to tamsulosin , the subgroup of patients treated by HESr and who over expressed MIF at baseline , had a higher response to the International Prostate Symptom Score ( I‐PSS ) than those who did not over express this protein ( mean I‐PSS change : −6.4 vs. −4.5 respectively ) . As the study is exploratory , results should be confirmed in a powered clinical study . Conclusions These results showed for the first time at clinical level the anti‐inflammatory properties of HESr , already indicated in BPH‐related LUTS . Thus , HESr could be of interest to prevent unfavourable evolution in patients with CPI . Prostate 75:1857–1867 , 2015 . © 2015 The Authors . The Prostate Published by Wiley Periodicals ,
