Nonalcoholic fatty liver disease includes a wide spectrum of manifestations from simple steatosis to nonalcoholic steatohepa titis, fbrosis, and eventually cirrhosis or even hepatocellular carcinoma. This disorder is also associated with an increased cardiovascular risk, renal involvement, oncologic processes, metabolic disturbances, and an...

Encefalopatía hepática La encefalopatía hepática (EH) es un disturbio potencialmente reversible, de causa metabólica, que ocurre en pacientes con enfermedad hepática aguda o crónica, y que consiste en una alteración del funcionamiento del sistema nervioso central. Entre el 30%-50% de pacientes cirróticos que no muestran síntomas de EH clínica...

Identifying the most effective therapeutic intervention in patients with NAFLD is challenging. Precise stratification in clinical trials is key to ensuring the inclusion of patients who will benefit (and not those who will be harmed) and/or in whom the natural history can be improved. Clinical trials in NAFLD can provide useful information...

El nombre de una enfermedad no sigue ningún protocolo definido y es habitual la aceptación por parte de la comunidad científica de diversas variantes en función de las costumbres de cada lugar. Hay ejemplos de entidades prevalentes con curiosos procesos de denominación, como la diabetes mellitus. La primera palabra, "diabetes", proviene del...

After the publication of our meta-analysis, in which we demonstrated that aspartate aminotransferase (AST), alanine aminotransferase (ALT) and total bilirubin were related to a poor prognosis in patients suffering COVID-19, some authors raised the question about whether these findings are directly linked, or they are epiphenomena.

Hypoxic hepatitis (HH) (also known as ischemic hepatitis or shock liver) is characterized by a dramatic but transient rise in serum concentrations of hepatic enzymes caused by anox ic necrosis of centrilobular liver cells (1). Although the patho genesis is multifactorial –cardiac failure, respiratory failure and toxic-septic shock– (2), the...

Background: bioelectrical impedance analysis is a technique for the determination of the hydropic component. The hydropic component, determined by blood volume, could be a reflection of the hemodynamic situation. This study aimed to evaluate the usefulness of peripheral bioelectrical impedance analysis (BIA) for the prediction of hemodynamic...

Nonalcoholic fatty liver disease (NAFLD) is a clinical condition that encompasses various forms of liver damage not caused by chronic alcohol consumption. In the absence of other etiologies, it ranges from steatosis to nonalcoholic steatohepatitis and cirrhosis. The prevalence of NAFLD has considerably increased over the last years owing to the...

Management of non-alcoholic steatohepatitis is focused on restitution of metabolic derangement, weight loss and drugs able to improve steatosis, ballooning and fibrosis. Life-style interventions based on Mediterranean diet and increasing physical activity are the first line ther apy. In patients with unsuccessful life-style intervention several...

Acute-on-chronic liver failure (ACLF) represents a reversible syndrome associated with high short-term mortality, characterized by acute decompensation in patients with chronic liver disease and extrahepatic organ failure. Diagnosis and prognosis assessment is based on a newly developed diagnostic score, the Chronic Liver Failure Consortium...

The prevalence of non alcoholic fatty liver disease (NAFLD) has increased to 25% in the general population and could double by 2030. Liver fibrosis is the main indicator of morbidity and mortality and recent estimations suggest a substantial number of individuals with undiagnosed advanced liver disease. Strategies to monitor advanced fibrosis...

Background and aims: SARS-CoV-2 is mainly a respiratory virus that has relevant systemic effects. We assessed the impact of baseline liver function (aspartate aminotransfer ase [AST], alanine aminotransferase [ALT], bilirubin) on COVID-19-related outcomes, including mortality, intensive care unit (ICU) admissions, and non-fatal severe...

Interleukin 17 (IL-17) is an effector cytokine that plays a key role in the pathogenesis of both psoriasis and metabolic-associated fatty liver disease (MAFLD), a condition that is more prevalent and severe in patients with psoriasis. In liver inflammation, IL-17 is mainly produced by CD4+ T (TH17) and CD8+ T cells (Tc17), although numerous...

The prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing worldwide, reflecting the current epidemics of obesity, insulin resistance, type 2 diabetes mellitus, and metabolic syndrome. NAFLD is characterized by the accu mulation of fat in the liver, and is known to be a cause of cir rhosis. Although many pathways have been...

Background and Aim: Histological score systems may not fully capture the essential nonalcoholic steatohepatitis (NASH) features, which is one of the leading causes of screening failure in clinical trials. We assessed the NASH distribution and its components across the fibrosis stages and their impact on the prognosis and their relationship with...

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and a major public health problem worldwide. Liver fibrosis is closely correlated with liver functional reserve and the risk of HCC development. Meanwhile, malignant tumors generally have high cellularity compared to benign tumors, which results in increased stiffness....

Wilson's disease (WD) is a rare condition caused by copper accumulation primarily in the liver and secondly in other organs, such as the central nervous system. It is a hereditary autosomal recessive disease caused by a deficiency in the ATP7B transporter. This protein facilitates the incorporation of copper into ceruloplasmin. More than 800...

Metabolic dysfunction–associated fatty liver disease (MAFLD) prevalence and incidence is rising globally. It is associated with metabolic comorbidities, obesity, overweight, type 2 diabetes mellitus, and at least two metabolic risk factors, such as hypertension, hypertriglyceridemia, hypercholesterolemia, insulin resistance, and cardiovascular...

Background & Aims: Autophagy-related gene 3 (ATG3) is an enzyme mainly known for its actions in the LC3 lipidation pro cess, which is essential for autophagy. Whether ATG3 plays a role in lipid metabolism or contributes to non-alcoholic fatty liver disease (NAFLD) remains unknown. Methods: By performing proteomic analysis on livers from...
