NAFLD in adolescenti e giovani adulti con PCOS
Malattia del fegato grasso non alcolico (NAFLD), resistenza all'insulina e dislipidemia in adolescenti e giovani adulti con sindrome dell'ovaio policistico (PCOS)
This project focuses on an at-risk adolescent and young adult population who may gain long-term health benefits from detection of risk factors at a young age. The primary aims of this proposal are: 1) To observe whether adolescents and young adults with Polycystic Ovary Syndrome (PCOS) are more likely to have elevated liver fat (>/=4.8%) than controls by studying liver fat deposition measured by magnetic resonance spectroscopy (MRS); 2) To assess the association of percentage liver fat with biomarkers of Non-alcoholic fatty liver disease (NAFLD), dyslipidemia, insulin resistance and body composition in PCOS and controls.
In the proposed study, 40 adolescents and young adults with PCOS and 40 age-comparable control subjects will be evaluated for metabolic disturbances and elevated liver fat using noninvasive and state-of-the-art techniques including MRI, dual-energy x-ray absorptiometry and an oral glucose tolerance test in order to fully assess the metabolic and body composition differences between these groups. This research proposal represents a critical step in understanding the metabolic and cardiovascular comorbidities of PCOS and their relationship to NAFLD. The investigator hopes to use the results generated by this research proposal in order to lay the groundwork for the prevention and treatment of metabolic disorders in adolescents with PCOS. The overarching goal is to decrease and prevent lifelong morbidity associated with this common disorder.
Panoramica dello studio
Stato
Descrizione dettagliata
PCOS is a common condition that frequently presents in adolescence and young adulthood and is defined by the presence of hyperandrogenism and ovulatory dysfunction. Affected individuals are at increased risk of insulin resistance, NAFLD and dyslipidemia, which are features associated with the metabolic syndrome, a major public health concern. The associations between PCOS and both insulin resistance and dyslipidemia have been extensively described; however, its association with NAFLD has only recently been noted and superficially studied in adolescents and young adults. Additionally, it has not yet been fully elucidated why seemingly healthy nonobese adolescents with PCOS are predisposed to insulin resistance and its related complications. The susceptibility of certain PCOS patients to developing NAFLD is theorized to be due to the following potentiating factors: insulin resistance, hyperandrogenemia, and a genetic predisposition.
