Diagnostic potential of serum direct markers and non invasive fibrosis models in patients with chronic hepatitis B

AIM: Liver biopsy is recommended in the majority of patients with chronic viral hepatitis for fibrosis evaluation. Because of the disadvantages of liver biopsy, many studies related to non-invasive biomarkers and scores have been performed. In this study, we aimed to assess the diagnostic value of serum direct markers and non-invasive fibrosis models to predict liver fibrosis in the treatment-naive chronic hepatitis B (CHB) patients and to compare their diagnostic performance. METHODS: This study included 58 patients with a diagnosis of CHB virus infection and 30 healthy controls. Hyaluronic acid, tissue inhibitor of matrix metalloproteinase 1 and amino-terminal propeptide of type III procollagen were measured by enzyme-linked immunosorbent assay; and the Original European Liver Fibrosis panel, the Enhanced Liver Fibrosis (ELF) panel, PP score, aspartate aminotransferase to platelet ratio index (APRI) and FIB-4 indexes were calculated using the formulas taken from previous publications. Fibrosis stage was determined using Ishak's scoring system. RESULTS: The fibrosis stages identified upon liver biopsy was F0 in 12 patients (20.7%), F1-2 in 36 (62.1%) and F3-5 in 10 (17.2%). The diagnostic value of all the non-invasive indices was low to detect mild fibrosis. We demonstrated that the diagnostic accuracy of HA is the best for predicting fibrosis of F3 or more (area under the receiver-operator curve, 0.902). In our study, the results from a combination of tests showed that ELF and APRI had the highest diagnostic value sensitivity of 90%, specificity of 100%, positive predictive value of 100% and negative predictive value of 96.4% for detection of fibrosis of F3 or more. CONCLUSION: In CHB patients, combination of ELF and APRI has a better diagnostic value in predicting fibrosis of F3 or more.
