Prospective validation of ELF test in comparison with Fibroscan and FibroTest to predict liver fibrosis in Asian subjects with chronic hepatitis B.

ABSTRACT:

Background and aims

Liver stiffness measurement (LSM) and FibroTest (FT) are frequently used as non-invasive alternatives for fibrosis staging to liver biopsy. However, to date, diagnostic performances of Enhanced Liver Fibrosis (ELF) test, which consists of hyaluronic acid, aminoterminal propeptide of procollagen type-III, and tissue inhibitor of matrix metalloproteinases-1, have not been compared to those of LSM and FT in Asian chronic hepatitis B (CHB) patients.

Methods

Between June 2010 and November 2011, we prospectively enrolled 170 CHB patients who underwent liver biopsies along with LSM, FT, and ELF. The Batts system was used to assess fibrosis stages.

Results

Areas under receiver operating characteristic curves (AUROCs) to predict significant fibrosis (F?2), advanced fibrosis (F?3), and cirrhosis (F?=?4) were 0.901, 0.860, and 0.862 for ELF, respectively; 0.937, 0.956, and 0.963 for LSM; and 0.896, 0.921, and 0.881 for FT. AUROCs to predict F?2 were similar between each other, whereas LSM and FT had better AUROCs than ELF for predicting F?3 (both p<0.05), and LSM predicted F4 more accurately than ELF (p<0.05). Optimized cutoffs of ELF to maximize sum of sensitivity and specificity were 8.5, 9.4, and 10.1 for F?2, F?3, and F?=?4, respectively. Using suggested ELF, LSM and FT cutoffs to diagnose F1, F2, F3, and F4, 91 (53.5%), 117 (68.8%), and 110 (64.7%) patients, respectively, were correctly classified according to histological results.

Conclusions

ELF demonstrated considerable diagnostic value in fibrosis staging in Asian CHB patients, especially in predicting F?2. However, LSM consistently provided better performance for predicting F?3 and F4.

Project description:Vibration controlled transient elastography (FibroScan) is used to predict the severity of liver fibrosis and steatosis. In pediatrics, few studies have been performed directly comparing liver histologic features with FibroScan liver stiffness measurements (LSMs) and controlled attenuation parameters (CAPs). The FibroScan-aspartate aminotransferase (FAST) score, which predicts liver disease severity in adult nonalcoholic fatty liver disease (NAFLD), has not been analyzed in children. The aims of this study were to determine if LSM and CAP correlated with liver histologic fibrosis stage and steatosis grade, respectively, and to determine the predictive capacity of FAST in pediatric NAFLD. Research participants (n = 216) included those with FibroScan within 90 days of a liver biopsy. The ability of LSM, CAP, and FAST to predict severity of liver disease was analyzed by Spearman correlation, linear regression, and receiver operating characteristic and C statistic. Significant correlations were identified between LSM and Ishak fibrosis stages, with the strongest correlation occurring in the non-NAFLD group (Spearman r = 0.47, p < 0.0001). LSM adequately predicted Ishak stages F0-2 versus F3-F6 (area under the receiver operating characteristic curve [AUROC], 0.73 for all; 0.77 for non-NAFLD). CAP strongly predicted histologic steatosis grade (r = 0.84; p < 0.0001; AUROC, 0.98). FAST had acceptable discriminatory ability for significant liver disease (AUROC, 0.75). A FAST cutoff ≥0.67 had a sensitivity of 89% but a specificity of only 62% at determining significant liver disease. This study encompasses one of the largest pediatric cohorts describing the accuracy of FibroScan LSM and CAP to predict liver histologic fibrosis stage and steatosis grade, respectively. In order to determine specific LSM, CAP, and FAST cut-off values for fibrosis stages, steatosis grades, and significant liver disease, respectively, a much larger cohort is necessary and will likely entail the need for multicentered studies.
