Abstract:
Objective:To explore the safety of inactivated novel coronavirus vaccine inoculation and the fluctuating neutralizing antibody in patients with chronic hepatitis B (CHB).Methods:Retrospective and prospective epidemiological research methods were employed. 153 CHB patients who visited the Department of Infectious Diseases at the First Hospital of Shanxi Medical University from September 2021 to February 2022 were selected as the research subjects. Information on vaccination-related adverse reactions was collected. Colloidal gold immunochromatography was used to identify neutralizing antibodies in the body after 3-6 months of vaccination. Statistical analysis was performed using the χ2-test or Fisher's exact test. Results:The positive rates of neutralizing antibodies after inactivated novel coronavirus vaccine inoculation in 153 patients with CHB were 45.50%, 44.70%, 40.00% and 16.20%, respectively, at 3, 4, 5, and 6 months. The neutralizing antibody concentrations were 10.00 (2.95, 30.01) U/ml, 6.08 (3.41, 24.50) U/ml, 5.90 (3.93, 14.68) U/ml, and 1.25 (0.92, 3.75) U/ml, respectively. The difference was not statistically significant ( P>0.05) when the neutralizing antibody positivity rates in hepatitis B virus (HBV) DNA-negative and positive patients and HBeAg-negative and positive patients at different time points were compared. The overall incidence of adverse reactions following vaccination was 18.30%. Pain at the site of inoculation and fatigue were the main presentations, and no serious adverse reactions occurred. Conclusion:CHB patients, when inoculated with an inactivated novel coronavirus vaccine, can produce neutralizing antibodies, which can stay at certain levels for 3, 4, and 5 months. However, the neutralizing antibody level gradually decreases over time, and the decrease is remarkable at 6 months. So, it is recommended to boost vaccinations at an appropriate time. Additionally, the results of the study suggest that HBV replication status has little effect on the production of neutralizing antibodies in CHB patients with relatively stable liver function, which means the inactivated novel coronavirus vaccine has a good safety profile.
