Clinical Course and Predictors of Metabolic Dysfunction Associated Steatotic Liver Disease in Obese Children and Adolescents
摘要
To evaluate the course and predictors of outcome of metabolic dysfunction-associated steatotic liver disease (MASLD).
MethodsRecords of 100 obese children with MASLD were reviewed for change in body mass index (BMI) and alanine aminotransferase (ALT) levels.
ResultsA total of 100 (73 boys) children with mean (SD) age 12.1 (2.8) years followed for 2.0 (1.6) years were included. Normalization in ALT levels occurred in 72 (72%) at 1.1 (0.8) years of follow-up; 17 (23.6%) relapsed after 1.6 (1.3) years. Sustained remission (n = 55; 55%) was associated with greater BMI Z-score reduction (%) [median (q1, q3) 15.3 (5.1, 25.5) vs. 3.4 (− 4.3, 11.1); P < 0.001]. Multivariate regression identified BMI Z-score reduction as the only predictor of remission (OR 6.67, 95%CI 1.54–33.3; P = 0.007). ROC analysis showed BMI Z-score reduction of 13.8% predicted remission with an area under curve of 0.72 (95%CI: 0.62, 0.82; P < 0.001).
ConclusionPediatric MASLD has a variable course, with remission dependent on the reduction in BMI Z-score.
