Nonalcoholic fatty liver disease, associated lipidomic changes, and preeclampsia risk

非酒精性脂肪肝、相关脂质组学变化和先兆子痫风险

基本信息

项目摘要

PROJECT SUMMARY Preeclampsia (PE) is a leading cause of maternal morbidity and mortality in the United States which has led to an urgent need to accurately predict its risk. It is not known how nonalcoholic fatty liver disease (NAFLD), the liver manifestation of metabolic syndrome and the most prevalent liver disease among women, contributes to PE risk. The long-term objective of this proposal is to define the relationship between NAFLD and PE, to identify strategies to reduce the risk of PE, and to improve short- and long-term maternal outcomes in this population. This project will evaluate the independent association of NAFLD with PE among overweight and obese women. It will also study relevant lipid alterations in women with NAFLD in pregnancy which are associated with endothelial dysfunction that leads to the clinical syndrome of PE, among NAFLD (compared to non-NAFLD) patients during pregnancy. The Specific Aims of this proposal are: (1) To prospectively assess whether NAFLD is an independent risk factor for: i) PE among overweight/obese women and ii) PE with liver injury; (2) To determine whether women with NAFLD in pregnancy have altered levels of bioactive lipids associated with endothelial cell dysfunction, compared with women without NAFLD in pregnancy. This study will be performed in the Mount Sinai Health System, which provides care to a diverse and multiethnic patient population disproportionately affected by both NAFLD and PE. This application will support the candidate's career development into an independent patient-oriented investigator focused on the influence of liver disease in pregnancy on preeclampsia risk and future maternal cardiovascular and liver health, a significant unmet need. The proposed career development plan integrates advanced coursework in translational epidemiology, lipidomics assessment, prospective study design/ analysis, and biostatistics, and experiential learning through the conduct of the proposed research plan, all within a highly supportive research environment. The mentorship team which includes senior investigators with expertise in epidemiologic and translational research in hepatology (Friedman and Terrault), preeclampsia (Roberts), and prospective study design and advanced biostatistical analysis (Sigel), will guide the candidate's research and career development. The superb institutional infrastructure for developing successful clinical investigators and the substantial institutional commitment to the candidate greatly strengthen this application. At the conclusion of this proposal's funding period, Dr. Kushner will be optimally positioned as an independent physician-investigator studying the intersection of liver disease and PE, and their implications on future maternal health.
