A 2-year-old girl from urban Delhi presents with a 3-week history of progressive swelling of face, limbs, and abdomen. She has been eating a diet predominantly of rice and lentils with minimal animal protein. On examination, she is lethargic, has bilateral pitting edema, hepatomegaly (3 cm below costal margin), and a characteristic 'flaky paint' dermatitis on the extensor surfaces. Serum albumin is 1.8 g/dL, and she has hypoglycemia (blood glucose 45 mg/dL). What is the most appropriate immediate next step?

Explanation

## Clinical Diagnosis: Kwashiorkor This child has **acute protein deficiency (kwashiorkor)**, characterized by: - Bilateral pitting edema (hallmark) - Hepatomegaly with fatty infiltration - Flaky paint dermatitis (peeling skin) - Lethargy and hypoglycemia - Very low albumin (<2 g/dL) - Predominantly protein-deficient diet ## Immediate Management Priority **Key Point:** Kwashiorkor is a **medical emergency** because of severe metabolic derangements: hypoglycemia, electrolyte imbalances, impaired immune function, and high mortality if not managed urgently. **High-Yield:** The immediate management sequence for kwashiorkor: 1. **Correct hypoglycemia** — IV 10% dextrose (NOT 25% or 50%, which risk hyperglycemia rebound) 2. **Admit to hospital** — for continuous monitoring and supervised rehabilitation 3. **Assess and correct electrolytes** — K^+^, Mg^2+^, PO~4~^3−^ are depleted despite normal serum levels 4. **Micronutrient repletion** — vitamin A, zinc, folate (start immediately) 5. **Gradual nutritional rehabilitation** — start at 50 kcal/kg/day, increase slowly to avoid refeeding syndrome 6. **Monitor for complications** — infections, diarrhea, cardiac arrhythmias ## Why NOT Diuretics? **Warning:** Diuretics are **contraindicated** in kwashiorkor: - Edema is due to hypoalbuminemia and sodium retention, not fluid overload - Diuretics worsen electrolyte depletion and precipitate cardiac arrhythmias - Edema resolves spontaneously with nutritional rehabilitation ## Comparison: Marasmus vs. Kwashiorkor | Feature | Marasmus | Kwashiorkor | |---------|----------|-------------| | Onset | Gradual (months) | Acute (weeks) | | Edema | Absent | **Present** | | Albumin | Low (2–3 g/dL) | **Very low (<2 g/dL)** | | Hepatomegaly | Mild | **Severe** | | Hypoglycemia | Moderate | **Severe** | | Dermatitis | Absent | **Present** | | Mortality | Lower | **Higher** | | Management | Gradual rehabilitation | **Urgent admission + IV support** | **Clinical Pearl:** Hypoglycemia in kwashiorkor reflects severe hepatic glycogen depletion and impaired gluconeogenesis. IV dextrose is life-saving and must be given immediately before oral feeding is attempted. **Mnemonic for Kwashiorkor signs: FLAKY PAINT** - **F**laky dermatitis - **L**ethargy - **A**scites / edema - **K**washi (protein deficiency) - **Y**ellow hair (sparse, depigmented) - **P**oor immunity - **A**lbumin very low - **I**nfections - **N**ail changes (Mees lines) - **T**emperament changes
