MADRID — Individuals with type 2 diabetes and/or obesity plus one or more metabolic risk factors are at a higher risk for metabolic dysfunction–associated steatotic liver disease (MASLD) with fibrosis and progression to more severe liver disease, stated new European guidelines that provide recommendations for diagnosis and management.
“The availability of improved treatment options underlines the need to identify at-risk individuals with MASLD early, as we now possess the tools to positively influence the course of the diseases, which is expected to prevent relevant clinical events,” stated the clinical practice guidelines, updated for the first time since 2016.
“Now we have guidelines that tell clinicians how to monitor the liver,” said Amalia Gastaldelli, PhD, research director at the Institute of Clinical Physiology of the National Research Council in Pisa, Italy, and a member of the panel that developed the guidelines.
Dr. Gastaldelli moderated a session focused on the guidelines at the annual meeting of the European Association for the Study of Diabetes (EASD). In an interview after the session, Dr. Gastaldelli, who leads a cardiometabolic risk research group, stressed the importance of the liver’s role in the body and the need for diabetes specialists to start paying more attention to this vital organ.
“It’s an important organ for monitoring because liver disease is silent, and the patient doesn’t feel unwell until disease is severe,” she said. “Diabetologists already monitor the eye, the heart, the kidney, and so on, but the liver is often neglected,” she said. A 2024 study found that the global pooled prevalence of MASLD among patients with type 2 diabetes was 65.33%.
Dr. Gastaldelli noted the importance of liver status in diabetes care. The liver makes triglycerides and very-low-density lipoprotein cholesterol, which are all major risk factors for atherosclerosis and cardiovascular disease (CVD), she said, as well as producing glucose, which in excess can lead to hyperglycemia.
The guidelines were jointly written by EASD, the European Association for the Study of the Liver, and the European Association for the Study of Obesity, and published in Diabetologia, The Journal of Hepatology, and Obesity Facts.
A Metabolic Condition
In the EASD meeting session, Dr. Gastaldelli discussed the reasons for, and implications of, shifting the name from nonalcoholic fatty liver disease (NAFLD) to MASLD.
“The name change focuses on the fact that this is a metabolic disease, while NAFLD had no mention of this and was considered stigmatizing by patients, especially in relation to the words ‘fatty’ and ‘nonalcoholic,’” she said.
According to the guidelines, MASLD is defined as liver steatosis in the presence of one or more cardiometabolic risk factor(s) and the absence of excess alcohol intake.
MASLD has become the most common chronic liver disease and includes isolated steatosis, metabolic dysfunction-associated steatohepatitis (MASH, previously NASH), MASH-related fibrosis, and cirrhosis.
In the overarching group of steatotic liver disease, a totally new intermediate category has been added: MASLD with moderate (increased) alcohol intake (MetALD), which represents MASLD in people who consume greater amounts of alcohol per week (140-350 g/week and 210-420 g/week for women and men, respectively).
The change in the nomenclature has been incremental and regional, Dr. Gastaldelli said. “The definition first changed from NAFLD to MAFLD, which recognizes the importance of metabolism in the pathophysiology of this disease but does not take into account alcohol intake. MAFLD is still used in Asia, Australasia, and North Africa, while Europe and the Americas have endorsed MASLD.”
