Uitkomstmaten
Primaire uitkomstmaten
Diagnostic accuracies of CAP and US for the detection of hepatic steatosis using 1H-MR Spectroscopy derived proton density fat fraction (MRS-PDFF) as reference standard.
Achtergrond van het onderzoek
CAPped is a study that compares the diagnostic accuracy of the controlled attenuation parameter (CAP) and ultrasonography (US) to detect hepatic steatosis in an overweight or obese paediatric population in the Netherlands using MRI-determined liver fat fractions as reference standard. Sixty subjects will be included and receive CAP, US and a MRI-scan, preferably on one day. All subjects are recruited in the Netherlands (with all study procedures performed in a single centre).
Doel van het onderzoek
Hepatic steatosis is becoming a large health burden in both Western and non-Western societies. In children, the trend of increasing obesity means more and more children are at risk of developing liver steatosis. As liver steatosis is a risk factor in the development of diabetes mellitus type 2 and cardio-vascular disease, there is a need for specific diagnostic tools that can identify the children with liver steatosis and if possible, quantify the amount of steatosis. Quantification will help clinicians to guide therapy. Several tools exist, such as ultrasonography (US), CT, serum test panels, MR Imaging, 1H-MR Spectroscopy and liver biopsy. However, all suffer from shortcomings. A new tool for quantifying steatosis is the Controlled Attenuation Parameter (CAP), available on the FibroScan (a device used to determine the presence of liver fibrosis). This tool has been investigated in adults thus far and has only been compared to the results of liver biopsy, a semi-quantitative score. In this study we will investigate our hypothesis that the Fibroscan/CAP can be used in obese children to identify those with steatosis and obtain a quantitative measure of the amount of liver fat and that its diagnostic accuracy is higher than of US.
Onderzoeksopzet
1. CAP-value measured with FibroScan device (at least once by examiner 1, time and schedule permitting twice by a second examiner), US and (availability pertaining) MRI at visit 1.
2. Depending on scanner availability, MRI was performed on a second visit in short proximity to visit 1.
