Treatment of Kwashiorkor Malnutrition
The treatment of kwashiorkor malnutrition requires a two-phase nutritional approach with specialized therapeutic formulas (F75 followed by F100 or RUTF), along with careful management of complications and correction of micronutrient deficiencies.
Understanding Kwashiorkor
Kwashiorkor is a form of severe acute malnutrition characterized by:
- Edema (often generalized)
- Skin changes (flaky paint dermatosis)
- Hair changes (depigmentation)
- Hepatomegaly
- Irritability
- Anorexia
Contrary to older beliefs, kwashiorkor is not simply a protein deficiency disease. Current evidence suggests it results from overall calorie deficiency combined with deficiencies of several type I nutrients that confer resistance to oxidative stress 1.
Treatment Protocol
Phase 1: Stabilization (Acute Phase)
Initial Formula: F75
- Used during the acute phase when the child is sick and has poor appetite
- Contains 75 kcal/100mL with lower protein and sodium content
- Prevents metabolic complications while restoring metabolic function
Medical Management of Complications
- Treat infections with appropriate antibiotics (amoxicillin for uncomplicated cases, ampicillin and gentamicin for complicated cases) 2
- Correct electrolyte imbalances (potassium, magnesium, calcium, phosphate) 2
- Manage fluid balance carefully (avoid aggressive rehydration which can lead to heart failure)
- Monitor for and treat hypoglycemia
- Provide vitamin and mineral supplementation
Micronutrient Supplementation
- Vitamin A
- Zinc
- Folate
- Vitamin B12
- Iron (only after infection is controlled)
- Vitamin D and calcium
Phase 2: Rehabilitation (Recovery Phase)
Transition to F100 Formula
- Higher energy and protein content (100 kcal/100mL)
- Used when appetite returns and edema begins to resolve
- Promotes rapid weight gain
Ready-to-Use Therapeutic Food (RUTF)
- Allows for home-based treatment after initial stabilization
- Preferred by mothers and dramatically improves coverage 1
- Contains essential nutrients for recovery
Monitoring Parameters
- Daily weight gain (target: 10-15g/kg/day)
- Resolution of edema
- Improved appetite
- Normalization of serum albumin levels
Special Considerations
Cautions in Treatment
- Avoid Rapid Refeeding: The physiology of malnourished children differs significantly from normal children; rapid refeeding can lead to refeeding syndrome
- Careful Fluid Management: Standard rehydration protocols can lead to circulatory overload and heart failure in malnourished children 1
- Medication Dosing: Many drugs require dose adjustments due to altered metabolism in malnutrition
Nutritional Requirements
- Energy: 25-30 kcal/kg/day is usually adequate during recovery phase 2
- Protein: Gradually increased as recovery progresses
- Monitor for specific deficiencies:
Follow-up and Prevention
- Regular nutritional screening and assessment
- Education on appropriate complementary feeding practices
- Community-based screening to identify children at risk before complications arise 1
- Long-term monitoring for growth and development
Common Pitfalls to Avoid
- Misdiagnosis: Kwashiorkor can be misdiagnosed in developed countries where it's less common 3
- Inappropriate Rehydration: Using standard rehydration protocols can be fatal
- Inadequate Micronutrient Supplementation: Focus only on macronutrients without addressing vitamin and mineral deficiencies
- Premature Transition Between Phases: Moving too quickly from F75 to F100 before metabolic stability is achieved
- Failure to Address Underlying Causes: Not identifying dietary restrictions, food insecurity, or malabsorptive conditions that led to malnutrition
Kwashiorkor can occur even in developed countries due to severe dietary restrictions 3, 4, homemade formula use, or as a complication of bariatric surgery 5, making it essential for healthcare providers to maintain vigilance for this condition in all settings.
