Аннотация
BACKGROUND: Pelvic organ prolapse (POP) is a prevalent condition caused by weakened pelvic floor support structures. Extracellular matrix alterations, including changes in collagen type I, collagen type III, and matrix metalloproteinase 1 (MMP-1), contribute to the pathogenesis of this condition. Human platelet-rich fibrin lysate (hPRF-L) is a novel regenerative treatment that has shown beneficial results in treating structural weaknesses related to various pelvic floor diseases, including POP.
METHODS: This study protocol aims to investigate the effects of hPRF-L injection on collagen I, III, and MMP-1 in the vaginal mucosa of a rat POP model. POP will be induced in female Sprague-Dawley rats, which will be randomly assigned to control, sham, and hPRF-L treatment groups. The hPRF-L group will receive weekly injections of hPRF-L (25, 50, or 75 μL) into the vaginal mucosa for 4 weeks. Vaginal tissue samples will be collected, and collagen type I, collagen type III, and MMP-1 expression will be evaluated using quantitative reverse transcription polymerase chain reaction and immunohistochemical analyses. Data analysis will be performed with ANOVA and post-hoc tests.
DISCUSSION: The findings from this study protocol are expected to provide valuable insights into the mechanisms by which hPRF-L impacts the structural integrity of the pelvic floor. By elucidating these mechanisms, this study aims to inform future POP treatment strategies. The anticipated results are an increase in collagen type I and III expression and a reduction in MMP-1 levels in the hPRF-L treatment group compared to the control and sham groups. These outcomes could support the use of hPRF-L as a regenerative therapy for managing POP, offering a potential alternative to more invasive surgical interventions.
CONCLUSION: The expected results will contribute to the development of less invasive treatments for POP, improving patient outcomes and quality of life.
