Insights
Children with acute lymphoblastic leukaemia (ALL) face over a 10-fold increased risk of invasive pneumococcal disease (IPD). This highlights the need for prophylactic interventions, such as vaccination, in this vulnerable pediatric group.
Area of Science:
- Pediatric Oncology
- Infectious Diseases
- Immunology
Background:
- Asplenia and immunodeficiency are known risk factors for invasive pneumococcal disease (IPD).
- Limited data exist on IPD risk in children with acute lymphoblastic leukaemia (ALL), a common childhood cancer.
Purpose of the Study:
- To determine the risk of IPD in children diagnosed with ALL.
- To compare IPD incidence in children with ALL to the general pediatric population.
Main Methods:
- Combined data from nationwide IPD surveillance and the German childhood cancer registry.
- Retrospective analysis of IPD incidence among children with ALL.
Main Results:
- Children with ALL exhibit a significantly higher risk (over 10-fold) of IPD compared to the general pediatric population.
- A notable proportion of IPD cases in children with ALL occur during maintenance chemotherapy.
Conclusions:
- Children with ALL represent a high-risk group for IPD.
- This population may benefit from prophylactic strategies, including pneumococcal vaccination, especially during chemotherapy.
Abstract:
Asplenia and other conditions of immunodeficiency are established risk factors for invasive pneumococcal disease (IPD). There are no current data available on the risk of IPD in children with acute lymphoblastic leukaemia (ALL), the most common type of childhood malignancy. This study combined data from a nation-wide surveillance for IPD and the German childhood cancer registry, and showed that children with ALL carry a more than 10-fold higher risk for IPD than the general paediatric population. As a substantial proportion of IPD occurs during maintenance chemotherapy, children with ALL may represent candidates for the evaluation of prophylactic interventions including vaccination.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
