Insights
A rare case of pediatric acute lymphoblastic leukemia (ALL) simultaneously presented with Group B Streptococcus bacteremia and meningitis. Early chemotherapy and antibiotics led to a favorable response, showing minimal residual disease.
Area of Science:
- Pediatric Oncology
- Infectious Diseases
- Hematology
Background:
- Infection poses a significant risk for morbidity and mortality in pediatric acute lymphoblastic leukemia (ALL), particularly during induction therapy.
- Bacterial infections are a leading cause of treatment-related complications in children undergoing ALL treatment.
Observation:
- This report details a rare instance of a 3-year-old girl with ALL who simultaneously developed Streptococcus agalactiae (Group B Streptococcus) bacteremia and meningitis.
- The patient presented with a complex clinical picture involving both the malignancy and a severe infection.
Findings:
- The patient received targeted antimicrobial therapy for the infection.
- An early induction chemotherapy regimen, including vincristine and dexamethasone, was initiated.
- Initial response to anti-neoplastic therapy was favorable, with minimal residual disease (MRD) of 1.12% on day 15, despite slow neurologic recovery.
Implications:
- This case highlights the critical need for prompt diagnosis and management of severe infections in pediatric ALL patients.
- It underscores the importance of balancing anti-leukemic treatment with aggressive infection control.
- The findings suggest that early induction chemotherapy can be effective even in the presence of severe bacterial infections, with careful monitoring.
Abstract:
Infection is a major cause of treatment-related morbidity and mortality in pediatric acute lymphoblastic leukemia (ALL). Most children with ALL who develop life-threatening bacterial infections do so during induction therapy. We describe a rare case of ALL presenting simultaneously with Streptococcus agalactiae group B Streptococcus bacteremia and meningitis in a 3-year-old girl. She received appropriate antimicrobial therapy and a 2-drug early induction regimen consisting of vincristine and dexamethasone, leading to slow neurologic recovery and a favorable initial response to anti-neoplastic therapy as evidenced by minimal residual disease of 1.12% on day 15 of induction.

Etiology
Three primary contributing factors have been identified.
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
