Abstract

Insights

Elevated remnant cholesterol significantly increases the risk of developing metabolic-associated fatty liver disease (MAFLD) or non-alcoholic fatty liver disease (NAFLD). This finding highlights remnant cholesterol as a key risk factor for these common liver conditions.

Area of Science:

  • Hepatology
  • Metabolic Disorders
  • Cardiovascular Research

Background:

  • Metabolic-associated fatty liver disease (MAFLD) is the most prevalent chronic liver condition.
  • MAFLD is closely linked to obesity, diabetes, and metabolic dysregulation.
  • It is characterized by hepatic lipid accumulation due to impaired lipid metabolism.

Purpose of the Study:

  • To evaluate the association between elevated remnant cholesterol levels and the incidence of MAFLD and non-alcoholic fatty liver disease (NAFLD).

Main Methods:

  • A systematic review and meta-analysis adhering to PRISMA guidelines.
  • Searched Cochrane Library and PubMed for studies up to March 21, 2025, on remnant cholesterol and fatty liver disease.
  • Included six cross-sectional studies with 45,821 participants; assessed data quality using JBI and ROBINS-I tools.

Main Results:

  • A significant association was found between higher remnant cholesterol levels and increased risk of MAFLD/NAFLD.
  • The meta-analysis revealed a relative risk (RR) of 3.18 (95% CI 1.89-5.37; p <0.00001).
  • High heterogeneity (I² = 99%) indicates a robust link between remnant cholesterol and hepatic disorders.

Conclusions:

  • Increased remnant cholesterol is a significant risk factor for MAFLD and NAFLD.
  • This finding underscores the importance of monitoring remnant cholesterol in liver health.
  • Remnant cholesterol levels are strongly associated with the prevalence of fatty liver diseases.

Overview of Lipid Metabolism

Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

Lipid-Lowering Drugs: Statins and Miscellaneous Agents

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Lipids: Dietary Sources and Requirements

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ meats, shellfish,...

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess the...
