The value of APGA score, fibrosis index for diagnosing liver fibrosis in patients with chronic hepatitis B: doi: 10.7417/CT.2024.5054

Abstract

Background. Various non-invasive methods have been studied for assessing the fibrosis stage in patients with chronic hepatitis B. However, the performance of APGA, Fibrosis index in diagnosing liver fibrosis remains unclear globally and specifically in Vietnam.
Methods. An analytical cross-sectional study was performed among 242 patients treated at Thong Nhat Hospital.

Results. Both the APGA index and Fibrosis index showed good accuracy in diagnosing significant fibrosis (≥ F2), advanced liver fibro sis (≥ F3), and cirrhosis (F4) with an area under the curve (AUROC) greater than 0.7. AUROC value of APGA index, Fibrosis index for diagnosing signifcant fibrosis (≥ F2) were 0.828, 0.767 respectively. AUROC value of APGA index, Fibrosis index for diagnosing advanced liver fibrosis (≥ F3) were 0.784, 0.755 respectively. AUROC value of APGA index, Fibrosis index for diagnosing cirrhosis (F4) were 0.736, 0.782 respectively. APGA index and the Fibrosis index were significantly positively correlated with the fibrosis stage (p < 0.001), with the APGA index showing the strongest correlation (r = 0.51, p < 0.001).

Conclusions. The APGA values of 6.23, 7.88, and 8.99 can serve as cutoff points for the diagnosis of significant fibrosis (≥F2), advanced fibrosis (≥F3), and cirrhosis (F4) when combined with ARFI data.
