Abstract: Biopsy has been considered the method of choice for staging fibrosis in liver disease. However, as it is an invasive method subject to sampling errors and morbidity, new non-invasive methods have been proposed for the assessment of liver fibrosis. To evaluate and compare serum fibrosis biomarkers (APRI and FIB4) with transient liver elastography (THE), gold standard in this study in patients with chronic viral hepatitis B and C. Cross-sectional study of patients with chronic hepatitis B or C virus undergoing THE. The patients were evaluated using serum liver fibrosis markers APRI and FIB4. The degree of fibrosis ≥ 2 of the Metavir classification was defined as significant fibrosis. The diagnostic performance of both methods was calculated and compared using the ROC curve (AUROC). The study included 73 patients, 50 with HBV and 23 with HCV; 50.7% were female, mean age 48.6 ± 13.3 years. Significant fibrosis was observed in 31 patients. The accuracy of serum markers in the diagnosis of liver fibrosis was determined by AUROC, APRI 0.79 and FIB4 0.76 (P = .0.42); PPV and NPV APRI 91.7% and 76.9% respectively; FIB4, PPV = 87.5% and NPV = 77.8%. The study demonstrated that there was no difference in diagnostic performance between the APRI and FIB4 methods, which were considered tests with good accuracy in the diagnosis of significant fibrosis in patients with chronic viral hepatitis.
