The link between the gut environment and the prostate has recently been proposed as a potential therapeutic approach for treating benign prostatic hyperplasia (BPH). Therefore, this study examined the advantages of a novel oral probiotic supplement to improve intestinal health and treat BPH. A 3D intestinal barrier model that simulated oral intake was used to analyse the combined regulative abilities of Bifidobacterium longum and Bifidobacterium psychaerophilum. Then, a co-culture prostatic model was used to investigate the biological consequences of the combination under conditions mimicking BPH. The results show the connection between the gut microbiome and prostate disease since the probiotics successfully modulate the primary mechanism involved in the pathogenesis of BPH. Indeed, after the intestinal passage, the mediators released from B. longum and B. psychaerophilum induced a substantial decrease in reactive oxidative species of about 6 times and inflammation (about 5 times regarding interleukine-6 and 10) and a sharp increase in testosterone and serotonin levels (about 95%). Further, proliferation and BPH principal mediators (such as androgen and dihydrotestosterone) were highly affected and nearly restored to physiological levels. Thus, BPH can be directly affected by probiotic supplementation; specifically, B. longum and B. psychaerophilum, in combination, seem able to promote the mitigation of this disease.

Abstract
The link between the gut environment and the prostate has recently been proposed as a potential therapeutic approach for treating benign prostatic hyperplasia (BPH). Therefore, this study examined the advantages of a novel oral probiotic supplement to improve intestinal health and treat BPH. A 3D intestinal barrier model that simulated oral intake was used to analyse the combined regulative abilities of Bifidobacterium longum and Bifidobacterium psychaerophilum. Then, a co-culture prostatic model was used to investigate the biological consequences of the combination under conditions mimicking BPH. The results show the connection between the gut microbiome and prostate disease since the probiotics successfully modulate the primary mechanism involved in the pathogenesis of BPH. Indeed, after the intestinal passage, the mediators released from B. longum and B. psychaerophilum induced a substantial decrease in reactive oxidative species of about 6 times and inflammation (about 5 times regarding interleukine-6 and 10) and a sharp increase in testosterone and serotonin levels (about 95%). Further, proliferation and BPH principal mediators (such as androgen and dihydrotestosterone) were highly affected and nearly restored to physiological levels. Thus, BPH can be directly affected by probiotic supplementation; specifically, B. longum and B. psychaerophilum, in combination, seem able to promote the mitigation of this disease.File | Dimensione | Formato | |
