AIM To evaluate the performance of aspartate aminotransferase to platelet ratio(APRI) score against FibroS can in predicting the presence of fibrosis. METHODS Data of patients who concurrently had APRI score, Fibro Scan and liver biopsy to assess their hepatitis C virus(HCV) and hepatitis B virus(HBV) over 6 years were retrospectively reviewed and details of their disease characteristics and demographics were recorded. Advanced fibrosis was defined as ≥ F3. RESULTS Of the 3619 patients(47.5 ± 11.3 years, 97M:36F) who had Fibro Scans and APRI for HCV and HBV, 133 had concurrent liver biopsy. Advanced liver fibrosis was found in 27/133(20%, F3 = 21 and F4 = 6) patients. Although APRI score(P < 0.001, AUC = 0.83) and FibroS can(P < 0.001, AUC = 0.84) predicted the presence of advanced fibrosis, the sensitivities and specificities were only modest(APRI score: 51.9% sensitivity, 84.9% specificity; FibroS can: 63% sensitivity, 84% specificity). Whilst 13/27(48%) patients with advanced fibrosis had APRI ≤ 1.0, no patients with APRI ≤ 0.5 had advanced fibrosis, with100% sensitivity. The use of APRI ≤ 0.5 would avoid the need for FibroS can in 43% of patients. CONCLUSION APRI score and Fibro Scan performed equally well in predicting advanced fibrosis. A proposed APRI cutoff score of 0.5 could be used as a screening tool for FibroS can, as cut-off score of 1.0 will miss up to 48% of patients with advanced fibrosis. Further prospective validation studies are required to confirm this finding.
