The Microbiome in Childhood Acute Lymphoblastic Leukemia

Area of Science:

• Microbiome research
• Pediatric oncology
• Holobiont concept

Background:

• The holobiont concept views hosts and their associated microbes as a single ecological unit.
• Microbiome alterations are linked to host health, potentially influencing disease and aging.
• Pediatric acute lymphoblastic leukemia (ALL) research increasingly focuses on microbiome's role.

Purpose of the Study:

• To review current microbiome research in pediatric ALL patients.
• To understand the relationship between microbiome alterations and ALL etiology.
• To explore the impact of ALL treatments on the microbiome.

Main Methods:

• Literature review of recent microbiome studies in pediatric ALL.
• Analysis of microbiome diversity changes at diagnosis and during treatment.
• Identification of microbial signatures associated with ALL and treatment outcomes.

Main Results:

• Reduced microbiome diversity is observed in pediatric ALL patients at diagnosis.
• Chemotherapy significantly alters the microbiome, leading to side effects like infections.
• Specific microbial changes, such as Enterococcaceae dominance and Faecalibacterium depletion, are linked to outcomes.

Conclusions:

• Microbiome alterations are associated with pediatric ALL, though causality is unclear.
• Microbiome modulation strategies are being investigated for therapeutic potential.
• Further research is needed to elucidate the microbiome's role in ALL pathogenesis and treatment.
