A 50-year journey in the development of treatment for benign prostatic hyperplasia
Abstract
Recent research underscores the crucial role of hormone regulation in benign prostatic hyperplasia (BPH) and the therapeutic promise of growth hormone-releasing hormone (GH-RH) antagonists. BPH incidence in aging men doubled over three decades, driven by prostatic enlargement and lower urinary tract symptoms (LUTS). Aging-related changes in GH-RH and luteinizing hormone-releasing hormone (LH-RH) biology promote BPH through hormonal and inflammatory processes. Traditional therapies provide symptomatic relief but often fail to prevent progression. This review explores the 50-year extensive development of LH-RH and GH-RH peptide analogs from discovery to delivery and their potential in BPH treatment. In preclinical studies, GH-RH antagonists reduced prostate volume, improved LUTS, and modulated inflammation mediated by NF-κB and IGF-I. Clinical trials are needed to validate antagonist efficacy and safety. Given BPH’s public health impact among the aged, and especially among aging Veterans, integrating GH-RH antagonists into management strategies may offer precision-based therapeutic advancements.
