Objective: To investigate the influence of chemotherapy (CT) on HBsAb titer in patients receiving CT due to hematological malignancy.
Materials And Methods: The data of 75 patients who received CT with the diagnosis of various hematological malignancies and who had serum HBsAb levels measured prior to and after the cessation of CT were evaluated retrospectively.
Results: The median age of the patients was 52 years (range: 16-78) with 49 (65%) males and 26 (35%) females. Median HBsAb titer decreased significantly after CT compared to the pre-CT median HBsAb titer [68 (range: 0-1000) vs. 100 (range: 6.2-1000)] (p=0.001). In subgroup analysis, median HBsAb titer decreased significantly after CT in acute leukemia patients [110 (range: 6.2-1000) vs. 67.8 (range: 0-1000)] (p=0.003) and in patients receiving intensive CT [97.2 (range: 6.2-1000) vs. 71 (range: 0-1000)] (p=0.036). The decrease in median HBsAb titer was significant in male patients (p<0.001). HBsAb became negative after CT in 9 patients who were HBcAb-negative and had lower pre-CT HBsAb levels.
Conclusion: HBsAb decreased after CT, especially in acute leukemia and male patients, and in patients receiving intensive CT.

Article Synopsis
- Shift work may negatively impact physical health and immune response by disrupting circadian rhythms, prompting a study on hepatitis B vaccination in manufacturing workers.
- The study assessed 1,103 employees who received a three-dose HBV vaccine, tracking their antibody levels for three years to identify factors leading to vaccination failure.
- Results indicated shift workers had a higher failure rate in developing protective antibodies post-vaccination, suggesting the need for tailored vaccination strategies for individuals working non-traditional hours.
Investigation of Mother-to-Child Transmission of Hepatitis B in Yinchuan, China: Cross-Sectional Survey Study.
JMIR Public Health Surveill
September 2024
Department of Laboratory Medicine, Fujian Medical University, Fuzhou, China.
Background: Hepatitis B poses a significant global public health challenge, with mother-to-child transmission (MTCT) being the primary method of hepatitis B virus (HBV) transmission. The prevalence of HBV infection in China is the highest in Asia, and it carries the greatest burden globally.
Objective: This study aims to critically evaluate the existing local strategies for preventing MTCT and the proposed potential enhancements by analyzing the prevalence of hepatitis B among pregnant women and their neonates in Yinchuan.

Background: The use of hepatitis B virus (HBV)-positive donor kidneys to expand the donor pool has been implemented, but limited evidence exists regarding their impact on transplant outcomes. This study aimed to investigate the effects of donor HBV infection on transplant outcomes.
Methods: Donor and recipient data between 2015 and 2021 were collected.
Utility of a Third Heplisav-B Dose in Patients With Inflammatory Bowel Disease Without Immunity After 2-Dose Heplisav-B Vaccination.

Introduction: Hepatitis B virus (HBV) vaccination is recommended in patients with inflammatory bowel disease (IBD). Although the 2-dose Heplisav-B vaccine has proven effective, more than 20% of patients with IBD do not seroconvert. We prospectively evaluated the effectiveness of a third Heplisav-B dose in patients with IBD lacking HBV immunity despite 2-dose vaccination.
