Accuracy of International Guidelines in Identifying Normal Liver Histology in Chinese Patients With HBeAg-Positive Chronic HBV Infection.

Abstract

We evaluated the diagnostic accuracy of various international guideline criteria for identifying HBeAg-positive chronic HBV infection patients with no significant liver disease. A total of 1108 HBeAg-positive CHB patients were retrospectively enrolled. The guidelines assessed included those from the European Association for the Study of the Liver (EASL) 2017, the American Association for the Study of the Liver Disease (AASLD) 2018, the Asian Pacific Association for the Study of the Liver (APASL) 2015 and the Chinese Society of Hepatology (CSH) 2022. The CSH criteria demonstrated a higher proportion of patients with G0-1 and S0-1 (82.9%) compared to the EASL (75.9%), AASLD (75.3%) and APASL groups (58.8%). Additionally, the CSH criteria exhibited a significantly higher predictive value (AUC 0.782, 95% CI 0.754-0.809) than the EASL (AUC 0.765, 95% CI 0.737-0.793), AASLD (AUC 0.749, 95% CI 0.720-0.778) and APASL (AUC 0.720, 95% CI 0.690-0.750) criteria for identifying G0-1 and S0-1. Adding quantitative HBsAg levels (> 10⁴ IU/mL) to the EASL, AASLD and APASL criteria improved diagnostic performance. Consequently, the CSH guideline thresholds showed higher accuracy in identifying Chinese HBeAg-positive patients with no significant liver disease compared to EASL, AASLD and APASL criteria, emphasising the importance of considering quantitative HBsAg in the evaluation of HBeAg-positive chronic HBV infection.
