Pediatrics
A 3-year-old child presents for a rou7ne physical examina7on.
The parent is concerned that the child appears pale. The child's diet includes a lot of milk but very li]le red meat. Haemoglobin is 80 g/L with hypochromic and microcy7c indices. Which of the following is the most appropriate management?
Explanation
Core Concept: Nutritional Iron Deficiency Anemia (IDA) is the most common cause of anemia in childhood. Excessive cow's milk intake (>24 oz/day) in toddlers leads to IDA due to milk's low iron content, calcium-induced inhibition of iron absorption, and potential microscopic intestinal blood loss.
Clinical Presentation:
- Classic symptoms: Pallor, fatigue, irritability, pica (craving non-food items), and developmental delay.
- Complications: Cognitive and motor delays, severe anemia leading to heart failure.
Diagnosis:
- Diagnostic algorithm: CBC showing microcytic, hypochromic anemia.
- First-line diagnostic plan: CBC and iron studies (low ferritin, low serum iron, high TIBC).
- Gold standard: A therapeutic trial of iron with a documented reticulocyte response and rising hemoglobin within 4 weeks confirms the diagnosis without needing invasive tests.
Management:
- Acute management: Dietary modification (limit milk intake, introduce iron-rich foods) and oral elemental iron supplementation (3-6 mg/kg/day).
- Long-term/Definitive management: Continue iron therapy for 2-3 months after hemoglobin normalizes to replenish bone marrow iron stores, followed by a routine CBC follow-up.
