Title: Accuracy of Controlled Attenuation Parameter and Liver Stiffness Measurement in Patients with Non-alcoholic Fatty Liver Disease.
Abstract: We evaluated the diagnostic accuracy of the controlled attenuation parameter (CAP) and liver stiffness measurements (LSM) measured with either an M or XL probe against liver biopsy (LB) in patients with non-alcoholic fatty liver disease (NAFLD). This study was a cross-sectional prospective study that included 179 NAFLD patients. With a cutoff value for CAP &#8805;345, we can exclude significant steatosis in 87% (79.4%-92.5%) of our population. With respect to the LSM, the highest accuracy was obtained for F &#8805; F3 (area under the receiver operating characteristic curve [AUROC]&#8239;=&#8239;0.98) and F&#8239;=&#8239;F4 (AUROC&#8239;=&#8239;0.98). In a multivariable linear regression model, significant predictors influencing LSM were fibrosis stage (&#946;&#8239;=&#8239;2.6, p < 0.001) as a positive predictor and lobular inflammation (&#946;&#8239;=&#8239;-0.68, p&#8239;=&#8239;0.04) as a negative predictor, without significant influence after adjustment for CAP and probe type. We found that CAP is a satisfactory method for excluding advanced steatosis, while LSM is a good non-invasive marker for the exclusion of fibrosis.
