Elastographic evaluation for fatty liver disease in north Indian children and adolescents with type 1 diabetes.

Objectives: The prevalence and predisposing factors to metabolic dysfunction-associated fatty liver disease (MAFLD) in children with type 1 Diabetes (T1D) living in developing countries are unknown.

Methods: A cross-sectional study was conducted in children with T1D. The presence of liver fat and tissue stiffness were assessed by ultrasonography and shear-wave elastography (SWE), respectively. The SWE values were correlated to body mass index (BMI), glycemic control, disease duration, and gamma-glutamyl transferase (GGT). Healthy non-obese children (n=36) were recruited as controls.

Results: One hundred children with T1D were grouped (Group A-C) according to the disease duration (<5, 5-10, and >10 years, respectively). The mean diabetes duration and glycated hemoglobin were 5.9 ± 4.0 years and 8.2 ± 0.55 %, respectively. The mean SWE values were significantly higher in the patient groups compared to controls (5.07 ± 0.67, 5.27 ± 0.65, 5.16 ± 0.50, vs. 4.80 ± 0.82 kPa, p-value 0.006). The liver stiffness based on SWE showed a positive but weak relationship with BMI, diabetes duration, glycemic control, and GGT levels. A significantly higher number of children with T1D had MAFLD [9(20 %), 7(24.1 %), 7(26.9 %), vs. 1(3 %), p-value <0.001] based on ultrasonography.

Conclusions: Children with T1D showed higher liver stiffness values than controls. A weakly positive relationship of liver stiffness was observed with BMI, duration of diabetes, glycemic control, and serum GGT. Approximately one-fourth of children with diabetes showed sonographic evidence of hepatic steatosis. Larger studies are needed to ascertain the effects of obesity, diabetes duration, and metabolic control on the prevalence and progression of MAFLD in children with T1D.
