Author Summary
A total of 320 (37.5%) subjects had at least one ALT elevation (≥45 U/L) during follow-up
Male gender, baseline serum ALT and HBV DNA levels were statistically significantly associated with future ALT elevation
Serum HBV DNA level was the strongest predictor of ALT elevation during long term follow-up
HBV genotype, precore G1896A and BCP A1762T/G1764A mutations were not statistically associated with ALT elevation
The association between serum HBV DNA level and ALT elevation still holds when stratifying by HBV genotype, precore and BCP mutations
Author Conclusions
High viral load remained the most important risk factor for ALT elevation regardless of genotype, precore and BCP mutations
Lowering serum HBV viral load might be the key to prevent future elevation of ALT level
