Abstract

In this article, we comment on the article by Qu and Li, focusing specifically on the non-invasive diagnostic approaches for metabolic dysfunction-associated steatotic liver disease (MASLD). MASLD is the most common chronic liver disease in children. Nearly half of pediatric MASLD cases progress to metabolic dysfunction-associated steatohepatitis at diagnosis, often with comorbidities like renal disease, hypertension, type 2 diabetes, and mental health disorders. Early diagnosis and continuous intervention are crucial for managing this “silent organ” disease. Screening is recommended for children aged nine and older with obesity. Liver biopsy remains the diagnostic gold standard; however, due to its invasiveness, non-invasive methods - biomarkers, anthropometric algorithms, serum tests, and imaging - are increasingly vital. This editorial provides an overview of the current non-invasive diagnostic approaches for pediatric MASLD or liver fibrosis.

Core Tip: This article reviews non-invasive diagnostic approaches and liver fibrosis assessment methods for pediatric metabolic dysfunction-associated steatotic liver disease (MASLD), highlighting the recent nomenclature change and the significance of early diagnosis. MASLD is the most common chronic liver disease in children, with approximately half of the pediatric cases progressing to metabolic dysfunction-associated steatohepatitis at diagnosis and already having comorbidities such as renal disease, sarcopenia, hypertension, and type 2 diabetes mellitus. While liver biopsy is the gold standard for diagnosing MASLD, it is invasive. To avoid liver biopsy in children, developing non-invasive methods such as biomarkers, serum tests, and imaging is essential.
