Insights
Hepatitis B virus (HBV) prophylaxis effectively protected children with acute lymphoblastic leukemia (ALL) from new infections. All patients maintained protective anti-HBV titers or avoided infection despite varying prophylaxis strategies during ALL treatment.
Area of Science:
- Pediatric Oncology
- Immunology
- Infectious Diseases
Context:
- Acute lymphoblastic leukemia (ALL) is a common childhood cancer.
- ALL treatment often causes immunodeficiency, increasing infection risk.
- Hepatitis B virus (HBV) infection is a significant concern for these vulnerable patients.
Purpose:
- To evaluate the effectiveness of hepatitis B virus (HBV) prophylaxis in children undergoing treatment for acute lymphoblastic leukemia (ALL).
- To assess HBV infection rates and anti-HBV antibody titers in pediatric ALL patients receiving different prophylaxis regimens.
Summary:
- A study of 66 children with ALL investigated HBV prophylaxis strategies.
- Patients were grouped based on vaccination status before diagnosis and received various prophylaxis post-diagnosis.
- All patients achieved protective anti-HBV titers or remained free from de novo HBV infection, indicating successful prophylaxis.
Impact:
- Demonstrates that comprehensive HBV prophylaxis is effective in preventing new HBV infections in immunocompromised children with ALL.
- Highlights the importance of tailored HBV prophylaxis protocols for pediatric cancer patients.
- Contributes to improved management strategies for infectious complications in pediatric oncology.
Introduction:
Acute lymphoblastic leukemia (ALL) is the most common cancer in childhood. Immunodeficiency occurs very often during ALL treatment. Therefore, patients are susceptible to various infections (including hepatitis B).
Material And Methods:
The study group consisted of 66 children with ALL treated at the Department of Pediatric, Hematology and Oncology in Zabrze. Patients were divided into two groups with regard to active HBV prophylaxis before diagnosis. Group I included 22 patients who were vaccinated before diagnosis. Group II included 44 patients who were not vaccinated before diagnosis. After diagnosis active, passive and/or active-passive prophylaxis were administered to the patients.
Results:
In most patients, the anti-HBV titers were protective after ALL treatment completion. In the remaining children, with anti-HBV titers < 100 IU/ml, the HBV prophylaxis was also successful, because none of them experienced de novo HBV infection.
Conclusions:
Despite various models of HBV prophylaxis, the protection from new infection was effective in all children treated for ALL.
