Breath-holding spells in a patient with transient erythroblastopenia of childhood

Area of Science:

• Pediatrics
• Hematology
• Neurology

Background:

• Transient erythroblastopenia of childhood (TEC) is a common cause of anemia in young children.
• Breath-holding spells are common, typically benign, episodic events in childhood.

Observation:

• A pediatric patient presented with concurrent TEC and recurrent breath-holding spells.
• The child received oral iron supplementation for anemia.
• A notable decrease in breath-holding spells was observed shortly after initiating iron therapy.

Findings:

• Breath-holding spells resolved during iron supplementation, preceding the resolution of anemia.
• This suggests a potential direct effect of iron on the mechanisms underlying breath-holding spells.
• The findings point to a possible role for iron in autonomic nervous system regulation.

Implications:

• Iron supplementation may be a therapeutic option for children experiencing breath-holding spells, even in the absence of overt iron deficiency anemia.
• Further research is warranted to elucidate the precise mechanisms by which iron influences autonomic function and breath-holding episodes.
• This case highlights the importance of considering iron's broader physiological roles beyond erythropoiesis.
