- Abstract
Background: Due to limited data on the pathogenesis of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and the suboptimal therapeutic effect, the development of new and effective treatment modalities was needed urgently. Low‐intensity extracorporeal shock wave therapy (Li‐ESWT) has been reported for the treatment of CP/CPPS. However, the underlying mechanism remains to be elucidated. Objective: To interrogated the efficacy and the mechanism of Li‐ESWT in the treatment of CP/CPPS. Materials and Methods: According to different treatments, RWPE‐1 cells (human prostate epithelial cells) were randomly divided into three groups: control group, LPS (lipopolysaccharide) group, or Li‐ESWT group (LPS‐induced RWPE‐1 managed by Li‐ESWT). Following the Li‐ESWT treatment, the levels of oxidative stress were assayed. We then established a rat model of experimental autoimmune prostatitis (EAP) by injecting prostatic protein homogenate mixed with complete Freund's adjuvant. The Sprague‐Dawley rats were randomly divided into the control group, EAP group, or Li‐ESWT group. Von Frey Filament was used to quantify pelvic hyperalgesia in the rats. Prostates tissues from each group were collected for immunohistochemistry, oxidation stress, and Western blot analysis. Results: Histological analysis showed reduced inflammation and expression of cytokines (TNF‐α, IL‐1β, IL‐6, COX‐2, SP) in prostate tissues from the Li‐ESWT group compared with those from the EAP group (all p < 0.05). Similarly, there was reduced pelvic pain and allergic symptoms in the Li‐ESWT group compared with the EAP group (all p < 0.05). Besides, Li‐ESWT treatment could decrease oxidative stress in the prostate and in RWPE‐1 cells, respectively (both p < 0.05). Moreover, the Li‐ESWT upregulated the expression of CAT through the inhibition of phosphorylation of AKT/FOXO1 signaling pathway. Discussion and Conclusions: Li‐ESWT may reduce inflammation, oxidative stress, and pain in rats with autoimmunity‐induced prostatitis via the PI3 K/AKT/FOXO1 pathway. It implies that Li‐ESWT can present a potential therapeutic option for the treatment of CP/CPPS.
