Официальное название

Mechanisms in Hepatic Lipid Metabolism in Alcohol Use Disorder: From Genomics, Transcriptomics to Metabolomics

Обзор

Patients with hepatic steatosis due to alcohol will be offered liver biopsies when they enter a detoxification program. The first biopsy will occur in the first week of admission and the second in the fourth week when the steatosis has resolved. The hepatic transcriptome will be compared,

Подробное описание

Study Description:

The liver is central to lipid metabolism, intimately involved with lipid uptake, lipoprotein synthesis and lipid synthesis. Alcohol has known effects on changing lipid composition including increases in HDL and decreases in LDL; nevertheless, the underlying mechanisms of this altered lipoprotein metabolism is not understood. Current spectroscopy data characterize the changes in lipoprotein profiles with alcohol cessation. We aim to study liver lipid metabolism by performing liver biopsies and transcriptome analysis in participants with alcohol use disorder.

Objectives:

Primary Objective:

To understand the transcriptomics of hepatic lipid metabolism in alcohol use disorder

Secondary Objective:

To understand other transcriptome changes in alcohol use cessation.

Tertiary Objective:

To elucidate the genomics-transcriptomics-metabolomics pathway of hepatic lipid metabolism in alcohol use disorder.

Endpoints:

Primary Endpoints:

-Transcriptome changes in lipid metabolism between week 1 and week 4.

Secondary Endpoints:

-Other transcriptome changes between week 1 and week 4.

Tertiary Endpoints:

* To make connections with existing genetics and metabolomics data with transcriptomics. * Stool microbiome studies

Критерии участия

  • INCLUSION CRITERIA:

In order to be eligible to participate in this study, an individual must meet all of the following criteria:

  • Any individual >=18 years of age who is enrolled in 14-AA-0181 and is seeking inpatient treatment.
  • Vibration Controlled Elastography parameters with initial CAP of >295dB/m.

Критерии исключения

An individual who meets any of the following criteria will be excluded from participation in this study:

  • Pregnancy
  • Existing diagnosis of hyperlipidemia or essential hypertension
  • Hemoglobin A1c >= 6.5%
  • Waist to hip ratio: >=0.90 in males, >=0.85 in females
