Adverse transfusion reactions in transfused children

Area of Science:

• Pediatric Hematology
• Transfusion Medicine
• Clinical Pediatrics

Background:

• Child physiology and pathology differ significantly from adults, necessitating distinct transfusion guidelines.
• Adverse transfusion reactions (ATRs) in children vary in type and frequency compared to adults, with less established understanding.
• The prevalence of common ATRs is higher in children than adults, except for red blood cell alloimmunization in non-hemoglobinopathy patients.

Purpose of the Study:

• To highlight the specific considerations for blood transfusion in pediatric patients.
• To review the types, frequency, and understanding of adverse transfusion reactions in children.
• To emphasize the importance of early diagnosis and prevention strategies for ATRs in pediatric transfusion.

Main Methods:

• Literature review and analysis of studies focusing on pediatric transfusion reactions.
• Comparison of ATR prevalence and characteristics between pediatric and adult populations.
• Identification of frequently implicated blood products and specific ATRs in children.

Main Results:

• Allergic reactions are the most frequently reported ATR in pediatric transfusions, with platelet concentrates being the most implicated product.
• Early diagnosis of conditions like haemosiderosis is crucial for effective management and improved clinical outcomes.
• While overall ATR prevalence is higher in children, post-transfusion red blood cell alloimmunization is less common, excluding specific patient groups.

Conclusions:

• Pediatric transfusion practices require specialized guidelines due to physiological differences and distinct ATR profiles.
• Further clinical studies are needed to develop effective prevention strategies for ATRs in children.
• Advancements in technology, policy, and clinical practices are essential for enhancing transfusion safety in pediatric patients.
