    (Elsevier Espana, 2022) Okdemir, Sannur; Cakmak, Erol
    Introduction and objectives: Evaluation of liver fibrosis is important for treatment decisions, complications and to predict prognosis in patients with chronic hepatitis B (CHB). Our aim was to develop a new non-invasive fibrosis scoring method and prove its accuracy in the differentiation of no/low grade and advanced fibrosis in patients with CHB. Patients and methods: Our study included 273 chronic hepatitis B patients who underwent liver biopsy from February, 2007 to February, 2019 with medical records retrospectively reviewed. Preparations of these patients were divided into two groups as <= 3 no-low grade fibrosis (n=236) and >= 4 advanced fibrosis (n=37) according to histological ISHAK fibrosis scoring system. Results: The newly developed AGAP score and other non-invasive fibrosis scores; Fibrosis-4 index, Aspartate aminotransferase to platelets ratio, Gamma glutamyl transpeptidase to platelet ratio, Goteborg University Cirrhosis Index, King's score, Albumin-bilirubin index, Fibrosis cirrhosis index, Fibrosis index, Fibrosis quotient, Lok score and mean and/or median values of Fibroindex were significantly higher in the advanced fibrosis group compared to the no/low grade fibrosis group (p<0.001). However, there was no significant difference in AAR score among the groups (p=0.265). With cut-off value of 4.038, AUROC value of 0.803, sensitivity of 75.7%, specificity of 73.7% and accuracy of 0.740, AGAP score showed the best performance in advanced fibrosis differentiation compared to 12 other non-invasive fibrosis scoring methods. Conclusions: The newly developed AGAP score showed better performance in patients with CHB compared to 12 other non-invasive fibrosis scores in differentiation of no/low grade fibrosis and advanced fibrosis.
