Abstract

Background & Aims: Assessment of the severity of liver fibrosis is an important step in evaluating patients with chronic liver disease and determining their prognosis. We compared liver stiffness measurements (LSMs) made by supersonic shear imaging (SSI) with those of transient elastography (TE)-XL for their ability to determine the degree of liver fibrosis in overweight or obese patients with chronic liver disease. Methods: We performed a prospective study of 258 patients with chronic hepatitis of different etiologies and a body mass index greater than 25, evaluated at the University of Miami from October 2013 to December 2014. Liver stiffness was measured using the TE-XL probe and SSI of the right and left lobes during the same clinic visit, and comparisons were made for fibrosis stage in 124 biopsy-proven patients. In addition, further analysis was performed on a subgroup of 102 chronic hepatitis C virus (HCV)-positive patients for whom biopsy data were available. Results: Reliable LSMs were obtained from 96.1%, 94.6%, and 72.1% of patients using the TE-XL probe, SSI of the right lobe, and SSI of the left lobe, respectively. TE-XL, SSI of the right lobe, and SSI of the left lobe detected severe fibrosis (fibrosis stages 3-4), with area under the receiver operating characteristic curve (AUROC) values of 0.955, 0.954, and 0.910, respectively, compared with results from histologic analysis for the 124 biopsy-proven patients included in the study; these values were 0.952, 0.949, and 0.917, respectively, for the 102 biopsy-proven patients with HCV infection. TE-XL, SSI of the right lobe, and SSI of the left lobe detected fibrosis stage 4 with AUROC values of 0.920, 0.930, and 0.910, respectively, compared with histologic analysis, in all 124-biopsy proven patients, and with AUROC values of 0.907, 0.914, and 0.887, respectively, in the 102 biopsy-proven patients with chronic HCV infection. Conclusions: SSI and the TE-XL probe each accurately quantify liver fibrosis in overweight or obese patients with chronic liver disease, including those with HCV infection, when compared with data obtained from histologic analysis. SSI data obtained from the right lobe and the TE-XL probe can be used to evaluate fibrosis with similar accuracy.
