From UCSD 4/28/25: Children with Liver Disease Face Dramatically Higher Risk of Early Death (via Jeff Schwimmer’s X feed)

The findings, published April 22, 2025 in Hepatology, the scientific journal of the American Association for the Study of Liver Diseases, come from the Longitudinal InVestigation Evaluating Results of Steatosis (LIVERS) study, which followed 1,096 children over an average of 8.5 years. Nearly half of all deaths in the cohort were liver-related, and the overall mortality rate was 40 times higher than that of similar peers in the general U.S. population...

The retrospective cohort study used medical records and National Death Index data to follow children ages 2 to 18 who were diagnosed with MASLD between 2000 and 2017. Over an average of 8.5 years of follow-up, 3.4% of children had died…

In addition to the risk of early death, many children in the study developed serious health problems while still in their teens or twenties. These included high blood pressure (14%), obstructive sleep apnea (9.5%) and type 2 diabetes (7.3%). Problems with blood fats, such as high triglycerides or low HDL, were even more common — making dyslipidemia, the presence of abnormal levels of fats (lipids) in the blood, the most frequent complication overall.

My take: Since this was a retrospective single center study, the severity of the findings may be different with a more-representative national cohort. Nevertheless, this study shows that MASLD has serious consequences including premature death and numerous comorbidities.
