Background and study aim: The aim of this study was to evaluate the effectiveness of noninvasive tests in predicting liver fibrosis levels in chronic hepatitis B (CHB) patients.

Patients and methods: A total of 539 treatment naive patients aged 18 years and older with CHB who underwent liver biopsy were included. Patients with coinfections and comorbidities were excluded. Data were obtained retrospectively from patient’ follow- up files. Liver biopsy was evaluated according to the Ishak scoring system. SPSS 22.0 program was used for statistical analysis. Diagnostic sensitivity of APRI, FIB-4, NLR, GPR, AAR, RPR, API, King’s score, Fibro Q and MPV was determined for predicting ≥F2, ≥F3, ≥F4, ≥F5 groups.

Results: The median age of the CHB patients was 41 ±11.57 / year and 49.2% of the patients were female. The distribution of fibrosis stages was : F0, 16.5% ; F1, 26.4% ; F2, 39.7% ; F3, 10.4% ; F4, 4.1% ; F5, 2.4% ; F6 0.4%. Age, AST, ALT, GGT, ALP, RDW, HBV DNA levels were significantly higher, platelet and albumin levels were significantly lower in the ≥F3 group. All noninvasive tests except NLR and AAR predicted ≥F3 adequately (AUROC >0.5). King’s score for predicting ≥F2, ≥F5, and GPR for predicting ≥F3 had the highest diagnostic power. The tests predicted the fibrosis stage better, as the fibrosis stage progressed.

Conclusion: As a result; most of the noninvasive tests we evaluated could predict significant fibrosis and cirrhosis with significant accuracy. The rate of unnecessary biopsies can be reduced with the help of these noninvasive tests.
