Should echocardiogram be undertaken routinely when a child has severe iron deficiency anaemia?

Area of Science:

• Pediatric Cardiology
• Hematology

Background:

• Iron deficiency anaemia (IDA) is a prevalent condition in children, often managed with oral iron or, in severe cases, blood transfusions.
• Severe IDA can lead to cardiac complications, including left ventricular hypertrophy (LVH) and hypertension, necessitating careful monitoring.

Purpose of the Study:

• To report a unique case of severe nutritional IDA in a toddler with extreme anemia and associated cardiac dysfunction.
• To highlight the importance of echocardiography in assessing and managing cardiac complications in severe pediatric IDA.

Main Methods:

• A male toddler diagnosed with severe nutritional IDA (hemoglobin 1.7 g/dL) presented with hypertension and LVH on echocardiogram.
• Acute management involved packed red blood cell (PRBC) transfusion, followed by oral iron supplementation and antihypertensive medication.
• Serial echocardiograms and clinical follow-up were conducted over one year.

Main Results:

• Initial echocardiogram revealed significant LVH in the context of severe anemia and hypertension.
• Following treatment, LVH showed slight improvement after one month, while hypertension persisted.
• Complete resolution of cardiac findings and normalization of blood pressure were observed one year post-treatment.

Conclusions:

• Chronic nutritional IDA can induce structural cardiac changes that impact acute management strategies.
• Echocardiography is crucial for evaluating cardiac status in severe pediatric IDA cases.
• Close follow-up is essential to monitor cardiac recovery and persistent hypertension in children with severe IDA.
