Objective:
This study was conducted to re-recognize serological change patterns of patients with acute hepatitis B (AHB) by a highly sensitive detection technology, as well as to explore methods to select the optimal treatment opportunity.
Methods:
The biochemical and virological parameters of 558 AHB patients were analyzed retrospectively. The serological markers of hepatitis B virus and HBV DNA were detected by electrochemiluminescence immunoassay and automatic real-time fluorescent quantitative PCR, respectively.
Results:
At baseline, the positive rate of hepatitis B surface antigen (HBsAg) (86.2%) was significantly higher than the positive rate of HBV DNA (51.9%). Among the 58 patients with HBsAg-negative AHB, 16 were detected with trace amounts of HBV DNA at baseline. At 12 weeks, the HBsAg of 43 cases remained positive, and the mean level of HBsAg was 587.5IU/mL±313.4IU/mL. A total of 18 patients with HBsAg levels greater than 1500IU/mL at 12 weeks received interferon α-1b treatment and achieved HBsAg clearance within 24 weeks.
Conclusions:
Unlike traditional changing patterns, the clearance of HBV DNA in peripheral circulation for a few patients with AHB occurred later than HBsAg clearance. Detection of HBV DNA in peripheral circulation by highly sensitive detection technology could provide a diagnostic basis for those AHB patients who rapidly achieved HBsAg clearance before achieving HBV DNA clearance in their peripheral circulation and prevent misdiagnosis. Dynamic monitoring of the changes in HBsAg levels through highly sensitive detection technology could be used as a guide for the timely adoption of antiviral treatment with interferon and then AHB chronicity would be prevented.
