Insights
Children with type 1 diabetes (T1D) have increased liver stiffness and a higher prevalence of metabolic dysfunction-associated fatty liver disease (MAFLD). These factors weakly correlate with BMI, diabetes duration, and glycemic control.
Area of Science:
- Pediatric Endocrinology
- Hepatology
- Metabolic Disorders
Background:
- Metabolic dysfunction-associated fatty liver disease (MAFLD) is a growing concern in pediatric populations.
- The prevalence and risk factors for MAFLD in children with type 1 diabetes (T1D), particularly in developing countries, remain largely unknown.
Purpose of the Study:
- To investigate the prevalence of MAFLD and assess liver stiffness in children with T1D.
- To identify potential predisposing factors associated with MAFLD in this cohort.
Main Methods:
- A cross-sectional study involving 100 children with T1D and 36 healthy controls.
- Liver fat and stiffness were evaluated using ultrasonography and shear-wave elastography (SWE).
- SWE values were correlated with BMI, glycemic control, diabetes duration, and GGT levels.
Main Results:
- Children with T1D exhibited significantly higher liver stiffness (SWE values) compared to controls (p=0.006).
- Approximately 20-27% of children with T1D showed sonographic evidence of MAFLD, a significantly higher prevalence than in controls (p<0.001).
- Liver stiffness showed a weak positive correlation with BMI, diabetes duration, glycemic control, and GGT.
Conclusions:
- Children with T1D demonstrate increased liver stiffness and a higher prevalence of MAFLD.
- While correlations exist, factors like obesity, diabetes duration, and metabolic control require further investigation in larger studies to understand their impact on MAFLD progression in T1D.
- Findings highlight the need for increased awareness and monitoring of MAFLD in pediatric T1D patients, especially in resource-limited settings.
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.
