Infections in Children with Acute Lymphoblastic Leukemia

Area of Science:

• Pediatric Oncology
• Infectious Diseases
• Hematology

Background:

• Infections are common and life-threatening complications in children undergoing treatment for acute lymphoblastic leukemia (ALL).
• Understanding the epidemiological, clinical, and microbiological aspects of these infections is vital for effective management.

Purpose of the Study:

• To determine the epidemiological, clinical, and microbiological characteristics of infections in pediatric patients with ALL.
• To identify key factors influencing infection-related morbidity and mortality in this vulnerable population.

Main Methods:

• A retrospective study of 23 pediatric patients with ALL treated between 2015 and 2020.
• Analysis of 104 infectious episodes, focusing on infection sites, causative agents, treatment, and outcomes.

Main Results:

• Infectious episodes (IEs) were frequent (average 4.5 per patient), particularly during intensive treatment and associated with neutropenia.
• Respiratory tract infections were most common, with bacterial pathogens predominating.
• Antimicrobial therapy modifications and supportive care (G-CSF, IVIG) were frequently employed; no infection-related mortality was observed.

Conclusions:

• Pediatric ALL patients face a high burden of infectious episodes.
• Effective management strategies include close monitoring, prompt empirical antibiotic therapy for febrile neutropenia, and timely antimicrobial therapy adjustments.
• These interventions are critical for reducing infection-related morbidity and mortality in children with ALL.
