Acute Chest Syndrome in Children with Sickle Cell Disease: A Narrative Review

Area of Science:

• Pediatric Pulmonology
• Hematology
• Sickle Cell Disease Research

Background:

• Acute chest syndrome (ACS) is a frequent and serious pulmonary complication in pediatric sickle cell disease (SCD).
• ACS involves complex pathophysiology including vaso-occlusion, inflammation, infection, and hypoventilation.
• Prompt recognition and management are critical to prevent severe outcomes like respiratory failure.

Purpose of the Study:

• To review current evidence on the pathophysiology of ACS in children with SCD.
• To outline diagnostic criteria, clinical presentations, and risk factors for ACS.
• To summarize acute management strategies and long-term prevention of ACS.

Main Methods:

• Comprehensive literature review of existing studies on pediatric ACS.
• Synthesis of evidence regarding pathophysiology, clinical features, and treatment modalities.
• Analysis of preventative measures and disease-modifying therapies.

Main Results:

• ACS pathophysiology is multifactorial, with infection often serving as a trigger in children.
• Management varies from supportive care for mild cases to transfusions for severe presentations.
• ACS is linked to significant morbidity, including neurologic events and chronic pulmonary issues.

Conclusions:

• Effective management of ACS in pediatric SCD hinges on early diagnosis and tailored treatment.
• Preventative strategies, including disease-modifying therapies, are crucial for improving outcomes.
• Further research into ACS pathophysiology may yield novel therapeutic targets.
