Abstract
OBJECTIVE
The aim of this study was to compare the accuracy rate of liver stiffness calculated by shear wave elastography with liver biopsy results in obese and overweight children.
MATERIALS AND METHODS
Obese and overweight children between 3 and 18 years of age, who had hepatic steatosis and a healthy control group were included in this study. A blood sample was obtained for laboratory tests and shear wave elastography was performed for all subjects. Liver biopsies were performed only in patients with hepatosteatosis, providing permission for biopsy, and for whom the biopsy procedure was not contraindicated.
RESULTS
A cohort of 142 children (78 overweight/obese and 64 healthy) was included in this study. Shear wave elastography values were significantly higher in the patient group as com- pared to the control group (34.0 vs. 8.2 kPa; P < .001). Obese children had higher elastog- raphy values compared to non-obese children (50.2 vs. 23.7 kPa, P < .001). No correlation was detected between fibrosis score and elastography values. Elastography increased with increasing weight (correlation coefficient: 0.334, P = .003) and body mass index (correlation coefficient: 0.364, P = .001).
CONCLUSION
In obese and overweight patients, elastography values are higher than in healthy subjects as well as patients with liver fibrosis. Disease-specific cut-off, mean, and normal ref- erence range values should be defined with large-scale studies to improve interpretation of elastography values. Our results are contradictory in the determination of liver fibrosis with shear wave elastography in obese and overweight patients, thus further research with a larger patient population is recommended.
