Review
Non-alcoholic fatty liver disease (NAFLD) is becoming increasingly prevalent worldwide, especially in people with obesity, dyslipidemia, type 2 diabetes mellitus (T2DM), and metabolic syndrome. Weight loss and dietary modifications are established first-line treatments for NAFLD. Currently, there is no approved drug for NAFLD; however, pioglitazone and vitamin E have shown some beneficial effects. This systematic review covers the comparative efficacies of vitamin E, pioglitazone, and vitamin E plus pioglitazone. As of December 2022, the sources for prior literature review included PubMed, PubMed Central, and Medline. We included studies assessing the efficacy of pioglitazone, vitamin E, and vitamin E plus pioglitazone in improving liver histology, liver markers, and lipid profile when compared to other interventions in patients with NAFLD/non-alcoholic steatohepatitis (NASH). Review materials include randomized control trials (RCTs), traditional reviews, systematic reviews, meta-analyses, and observational studies on human participants published within the last five years in the English language. Studies on animals, pediatric populations, and with insufficient data were excluded from the review. Two authors scanned and filtered articles independently and later performed quality checks. A third reviewer resolved any conflicts. The risk of bias was assessed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines for systematic reviews, the Cochrane Risk of Bias Tool for RCTs, and the Scale for the Assessment of Narrative Review Articles for Traditional Reviews. A total of 21 articles were shortlisted. The results showed that pioglitazone and vitamin E are effective in reducing steatosis, inflammation, and ballooning, reducing liver markers, but there seem to be conflicting data on fibrosis resolution. Pioglitazone decreases triglycerides and increases high-density lipoproteins. One study has suggested that pioglitazone has superior efficacy to vitamin E in fibrosis reduction and vitamin E plus pioglitazone has superior efficacy than pioglitazone alone for NASH resolution. However, these conclusions require further validation through extensive analysis and additional research. In conclusion, diabetic patients with NAFLD can be given pioglitazone, and non-diabetic patients with NAFLD can be given vitamin E.

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.
