Detangling the interrelations between MAFLD, insulin resistance, and key hormones.

Hormones (Athens)

December 2022

Faculty of Medicine, National Autonomous University of Mexico, Av. Universidad 3000, Coyoacán, 4510, Mexico City, Mexico.

Metabolic dysfunction-associated fatty liver disease (MAFLD) has increasingly become a significant and highly prevalent cause of chronic liver disease, displaying a wide array of risk factors and pathophysiologic mechanisms of which only a few have so far been clearly elucidated. A bidirectional interaction between hormonal discrepancies and metabolic-related disorders, including obesity, type 2 diabetes mellitus (T2DM), and polycystic ovarian syndrome (PCOS) has been described. Since the change in nomenclature from non-alcoholic fatty liver disease (NAFLD) to MAFLD is based on the clear impact of metabolic elements on the disease, the reciprocal interactions of hormones such as insulin, adipokines (leptin and adiponectin), and estrogens have strongly pointed to the intrinsic links that lead to the heterogeneous epidemiology, clinical presentations, and risk factors involved in MAFLD in different populations.

Hum Mol Genet

November 2022

Centro Nacional de Genotipado (CEGEN), Universidade de Santiago de Compostela, 15706 Santiago de Compostela, Spain.

Article Synopsis
  • A genome-wide study involving nearly 12,000 COVID-19 positive cases in Spain identified significant genetic variants linked to hospitalization, with specific loci associated with males (3p21.31, 21q22.11) and females (9q21.32 near TLE1).
  • A second phase combined data with an additional cohort, revealing two new risk loci (9p13.3, 19q13.12) related to candidate genes AQP3 and ARHGAP33, and confirmed earlier findings in males for some loci.
  • The analysis highlighted genetic differences in COVID-19 severity between sexes and ages, with more pronounced heritability in males, particularly those over

A recent global outbreak of cases of acute hepatitis of unknown origin in children has raised health alerts. Increasing numbers of cases are being reported in most countries, mainly in the United Kingdom (UK). Although the cause remains unknown, several viruses have been isolated from affected children, including adenovirus, severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2), Epstein-Barr virus (EBV), and rhinovirus.

Background: Patients with liver diseases have complicated haemostatic alternations, resulting in both bleeding and thromboembolic complications, which cannot be sufficiently evaluated by conventional coagulation tests (CCTs), such as platelet count or prothrombin time. Thromboelastography (TEG) is a whole blood viscoelastic test which globally reflects changes in the haemostatic system, and its utility in evaluating patients with liver disease is increasingly recognised.

Aims: To review the current evidence and clinical significance of TEG in liver diseases.

Non-alcoholic fatty liver disease (NAFLD) affects 20-25% of the general population and is associated with morbidity, increased mortality, and elevated health-care costs. Most NAFLD risk factors are modifiable and, therefore, potentially amenable to being reduced by public health policies. To date, there is no information about NAFLD-related public health policies in the Americas.

Metabolic associated fatty liver disease (MAFLD) affects 20-30% of the worldwide population and is becoming the most common cause of chronic liver disease, cirrhosis and hepatocellular carcinoma (HCC). MAFLD is the hepatic expression of metabolic dysfunction correlated with a variety of metabolic comorbidities including obesity, dyslipidemia, hypertension and type 2 diabetes (T2DM). Obesity, altered gut permeability, chronic inflammation and dysbiosis related to MAFLD might predispose patients with cirrhosis to the development of acute-on-chronic liver failure (ACLF); however, this relationship remains unclear.

Non-alcoholic fatty liver disease (NAFLD) affects almost a quarter of the world's population and is the most common cause of chronic liver disease in children and adolescents. The recent proposal to replace the terminology of NAFLD with metabolic-associated fatty liver disease (MAFLD) aims to reflect the pathophysiology and risk factors for this disease. Importantly, the risk factors for MAFLD may be prenatal, such as genetic factors, or postnatal, such as obesity and insulin resistance.
