| Features | AASLD5 | EASL6 | APASL7 | KASL8 |
|---|---|---|---|---|
| Terminology | IT phase | HBeAg positive chronic infection | IT phase | IT phase |
| HBeAg | (+) | (+) | (+) | (+) |
| HBV DNA | >106 IU/mL | >107 IU/mL | Active HBV replication | >107 IU/mL |
| ALT | Normal ALT (<33 U/L for males, <25 U/L for females) | Persistently normal (<40 U/L) | Normal ALT | Persistently normal ALT (<34 U/L for males, <30 U/L for females) |
| Fibrosis/inflammation | None/minimal | None/minimal | None | None/minimal |
| Fibrosis assessment | Consider noninvasive methods (liver stiffness measurement, APRI, or FIB-4) or liver biopsy if persistent borderline normal or slightly elevated ALT, Age >40 years of age | A liver biopsy or a non-invasive test if elevated ALT | Consider biopsy if noninvasive tests suggest evidence of significant fibrosis, ALT persistently elevated, Age >35 years, or family history of HCC/cirrhosis | Consider biopsy if persistently elevated ALT, age >35–40 years |
