King’s Fibrosis, Fibrosis Index, GPR, and ALBI Score Are Useful Models for Liver Fibrosis in Chronic Hepatitis B Patients Pre- and Post-Treatment

Background: Liver fibrosis is one of the chronic hepatitis B (CHB) indications for treatment. Objectives: We aimed to assess the fibrosis index, FIB-4, King's fibrosis score, albumin-bilirubin (ALBI) score, gamma-glutamyl transferase-platelets (GPR), and gamma-glutamyl transferase-albumin (GAR) ratios as diagnostic models of liver fibrosis in CHB patients. Methods: The study enrolled 217 patients. Liver fibrosis was assessed by transient elastography, which showed 20.3% of the patients had F4 fibrosis. Treatment was given for 33.20 +/- 20.94 months. Results: F4 fibrosis patients had higher values (P = 0.001) of Fibrosis index score, FIB-4 score, King's fibrosis score, ALBI score, GPR, and GAR than non-F4 fibrosis patients. All patients had improved values after treatment. The mean treatment-induced changes were comparable in patients with and without virological response. The Fibrosis index of > 32.66 showed 63.64% sensitivity and 91.33% specificity. The FIB-4 score of > 1.88 had 72.73% sensitivity and 91.33% specificity. The King's fibrosis score of > 7.93 demonstrated 90.91% sensitivity and 73.99% specificity. The ALBI score of > -2.7 had 70.45% sensitivity and 86.13% specificity. The GPR value of > 0.69 revealed 70.5% sensitivity and 94.2% specificity. The GARvalue of > 1.28 showed 72.73% sensitivity and 46.4% specificity. The GAR was inferior to FIB-4 and GPR(P < 0.05). Conclusions: GPR, fibrosis index, King's fibrosis score, ALBI, and FIB-4 are useful diagnostic models of liver fibrosis in CHB patients.
