Unraveling the Interplay between Nonalcoholic Fatty Liver Disease and Polycystic Ovary Syndrome in Adolescents: Pathogenesis, Prevalence, and Management Strategies.

Abstract

BACKGROUND With the expanding understanding of conditions contributing to heightened cardiovascular risk, emerging pathologies like nonalcoholic fatty liver disease (NAFLD) and polycystic ovary syndrome (PCOS) are being recognized as hepatic and ovarian manifestations of metabolic syndrome, respectively. This study aims to elucidate the recent advancements in our comprehension of the link between these conditions in the pediatric demographic, focusing on pathogenesis, incidence, diagnostic methods, and effective therapeutic strategies. MATERIAL AND METHODS A systematic review was conducted following the PRISMA 2020 guidelines, with a search of the PubMed database for eligible studies published in the ten years leading up to January 2023. RESULTS Out of 23 reports based on 16 original studies, we found a significantly higher prevalence of NAFLD in adolescents with PCOS compared to healthy controls. Factors such as increased de novo lipogenesis, alterations in gut microbiota, and a deficiency in growth differentiation factor-15 have been implicated in their pathogenesis. Additionally, novel biomarker S100A4, a clinical prediction score for hepatic steatosis in PCOS, and pharmacotherapy involving low-dose spironolactone, pioglitazone, and metformin have been proposed to enhance the management of these conditions. CONCLUSIONS A meticulous approach to the prevention, detection, and treatment of NAFLD in adolescents with PCOS is paramount to mitigate further complications. The study underlines the need for ongoing research to refine our understanding and management of these interconnected metabolic disorders.
