ABSTRACT
AIM:
To evaluate the utility of the combination of alanine aminotransferase (ALT) course, hepatitis B virus (HBV) DNA level, and liver stiffness measurement (LSM) for determining significant liver disease in hepatitis B e antigen (HBeAg)-negative patients.METHODS:
Three hundred and ninety nine consecutive HBeAg-negative patients with HBV DNA >2000 IU/mL and documented serial measurements of ALT were enrolled to undergo LSM followed by liver biopsy.RESULTS:
Using ALT <40 IU/L as a normal value, 142 patients had persistently normal ALT (PNALT), whereas 257 had persistently or intermittently elevated ALT (PIEALT) in the prior year. Among patients with HBV DNA of 2000-19 999, 20 000-199 999, and ≥200 000 IU/mL, significant pathological lesions defined as the presence of moderate to severe necroinflammation and/or significant fibrosis by METAVIR scoring was present in 40%, 45%, and 71% of the PIEALT group, and 15%, 31%, and 36% of the PNALT group, respectively. In PNALT patients with HBV DNA <20 000 IU/mL, liver biopsy could be avoided in 88% when LSM <7 kPa is used as an indicator of non-significant liver histology but 12% of those who indeed had significant pathological lesions would be missed. In PIEALT patients with HBV DNA ≥20 000 IU/mL, the need for liver biopsy could be reduced by 53% with a false positive rate of 14% when LSM ≥7 kPa is used as a predictor of significant pathological lesions.CONCLUSION:
The combination of serial ALT, viral load, and LSM appears to be a promising non-invasive tool. A management algorithm for HBeAg-negative patients comprising these non-invasive measures is proposed with liver biopsy being pursued in selected cases.
