Long-term outcome after spontaneous HBeAg seroconversion in patients with chronic hepatitis B

During the course of chronic hepatitis B virus (HBV) infection, hepatitis B e antigen (HBeAg) seroconversion to its antibody (anti-HBe) often coincides with normalization of liver biochemical test and clinical remission, but data regarding long-term outcome after spontaneous seroconversion are still scarce. Excluding patients with other virus(es) concurrent infection, 283 patients with chronic HBV infection were followed up for at least 1 year after spontaneous HBeAg seroconversion to anti-HBe. Follow-up studies included clinical, biochemical, and virologic evaluation and hepatocellular carcinoma (HCC) screening with ultrasonography and alpha-fetoprotein assay. During a median follow-up period of 8.6 years…
