J Sae-wong et al. J Pediatr 2021; 230: 32-37. The Prevalence of Nonalcoholic Fatty Liver Disease and Its Risk Factors in Children and Young Adults with Type 1 Diabetes Mellitus
In this cross-sectional study with 50 children with Type 1 Diabetes Mellitus (T1DM), MRE and MRI-PDFF studies were undertaken to determine whether the participants had nonalcoholic fatty liver disease (NAFLD). Key findings:
- The median age and duration of T1D were 16.9 years (IQR, 13.6-20 years) and 6.5 years (IQR, 4-11 years), respectively. 26% of the cohort were overweight or obese.
- The prevalence of NAFLD was 10% (more than half had normal ALT values). Four out of 5 patients with NAFLD were overweight/obese, and 2 had an and elevated alanine aminotransferase (ALT) level. None had liver fibrosis (defined as MRE >2.9 kPa).
- High BMI-SDS (body mass index standard deviation score) was the sole independent risk factor associated with NAFLD (OR, 5.79; 95% CI, 1.04-32.18).
My take: This study is reassuring regarding the prevalence of NAFLD in children and young adults with T1D which was comparable to that in the general population. Routine screening for NAFLD in patients with T1D does not appear to be useful.
