Liver Disease

Liver disease is any condition that causes liver inflammation or tissue damage and affects liver function. The liver is the largest organ in the body and performs a number of vital functions such as converting nutrients derived from food into essential blood components, storing vitamins and minerals, regulating blood clotting, producing  proteins, enzymes, maintaining hormone balances, and metabolizing and detoxifying substances that would otherwise be harmful to the body. The liver also produces bile, a liquid that helps with digestion.


A moderate amount of alcohol is broken down by the liver without any damage. However, when drinking excessively, the liver can transform alcohol into fat and accumulate these lipids and become injured or seriously damaged. Liver injury can be determined by histology, abdominal ultrasonography and by testing the blood concentration of certain enzymes, such as gamma-glutamyltransferase (GGT), aspartate amino-transferase (AST), and alanine amino-transferase (ALT).

On the other hand, some studies suggest that moderate and regular consumption of alcoholic beverages may play a protective role against fatty liver disease, the exact mechanisms involved have not yet been clearly established.

BACKGROUND: Adherence to a Mediterranean diet (MedDiet) is thought to reduce liver steatosis. OBJECTIVES: To explore the associations with liver steatosis of 3 different diets: a MedDiet + extra-virgin olive oil (EVOO), MedDiet + nuts, or a control diet. METHODS: This was a subgroup analysis nested within a multicenter, randomized, parallel-group clinical trial, PREvencion con DIeta MEDiterranea (PREDIMED trial: ISRCTN35739639), aimed at assessing the effect of a MedDiet on the primary prevention of cardiovascular disease. One hundred men and women (mean age: 64 +/- 6 y), at high cardiovascular risk (62% with type 2 diabetes) from the Bellvitge-PREDIMED center were randomly assigned to a MedDiet supplemented with EVOO, a MedDiet supplemented with mixed nuts, or a control diet (advice to…
BACKGROUND & AIMS: Non-alcoholic and alcohol-related fatty liver disease are overlapping diseases in which metabolic syndrome and alcohol consumption each contribute to progressive liver disease. We aimed to assess the effects of alcohol consumption and metabolic syndrome on mortality in individuals with fatty liver. METHODS: We searched the National Health and Nutrition and Examination Survey III for adults (20-74 years old) with hepatic steatosis, detected by ultrasound, for whom mortality and follow-up data were available. We collected data from the alcohol use questionnaire (self-reported number of days a participant drank alcohol; the number of drinks [10 g alcohol] per day on a drinking day; the number of days the participant had 5 or more drinks) and calculated the average amount…
Importance: The prevalence of high-intensity binge drinking (HIBD), defined as consuming 2 or more times the binge threshold defined by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), is rapidly increasing in the United States. While the relationship between alcohol consumption and lipid and liver function enzyme (LFT) biomarkers has been previously examined, the associations of HIBD with those biomarkers remain unknown. Objective: To examine associations of HIBD with lipid and LFT levels in a cross-sectional sample enriched with participants who engage in HIBD. Design, Setting, and Participants: Cross-sectional study using data from the NIAAA clinical sample collected from March 3, 2005, to August 21, 2017, with participants recruited for either the NIAAA screening protocols or inpatient alcohol treatment…
OBJECTIVE: To evaluate the longitudinal relationship between repeated measures of alcohol consumption and risk of developing fatty liver. PATIENTS AND METHODS: This study includes 5407 men and women from a British population-based cohort, the Whitehall II study of civil servants, who self-reported alcohol consumption by questionnaire over approximately 30 years (1985-1989 through to 2012-2013). Drinking typologies during midlife were linked to measures of fatty liver (the fatty liver index, FLI) when participants were in older age (age range 60-84 years) and adjusted for age, socio-economic position, ethnicity, and smoking. RESULTS: Those who consistently drank heavily had two-fold higher odds of increased FLI compared to stable low-risk moderate drinkers after adjustment for covariates (men: OR = 2.04, 95%CI = 1.53-2.74; women:…
BACKGROUND: Alcohol is a known cause of cirrhosis, but it is unclear if the associated risk varies by whether alcohol is drunk with meals, or by the frequency or type of alcohol consumed. Here we aim to investigate the associations between alcohol consumption with meals, daily frequency of consumption, and liver cirrhosis. METHODS: The Million Women Study is a prospective study that includes one in every four UK women born between 1935 and 1950, recruited between 1996 and 2001. In 2001 (IQR 2000-03), the participants reported their alcohol intake, whether consumption was usually with meals, and number of days per week it was consumed. Cox regression analysis yielded adjusted relative risks (RRs) for incident cirrhosis, identified by follow-up through electronic…
