Metabolic dysfunction-associated fatty liver disease/metabolic dysfunction-associated steatotic liver disease: general provisions

Abstract

The literature review deals with the problem of metabolic dysfunction-associated fatty liver disease that is poorly studied in pediatric gastroenterology. Until recently, primary hepatic steatosis not associated with alcohol intake was defined as non-alcoholic fatty liver disease. Given the unity of the pathogenetic mechanisms underlying primary steatosis, associated steatohepatitis, liver fibrosis with metabolic disorders, such as visceral obesity, insulin resistance, meta-inflammation of adipose tissue, it was proposed to change the terminology. The authors present data on modern nomenclature definitions, etiological factors, prevalence, criteria of metabolic disorders and meta-inflammation associated with this nosology and specific to childhood. Metabolic dysfunction-associated fatty liver disease and nonalcoholic fatty liver disease are characterized by the development of hepatosteatosis. However, a distinguishing feature of metabolic dysfunction-associated fatty liver disease is the presence of metabolic disorders in a patient. It is believed that the use of the term “metabolic dysfunction-associated fatty liver disease” in clinical practice allows doctors to make a diagnosis more reliably and more accurately modify the patient’s lifestyle. Much attention is paid to the description of the heterogeneity of metabolic dysfunction-associated fatty liver disease in clinical practice, and a concise list of therapeutic options for metabolic dysfunction-associated fatty liver disease in childhood is presented.
