Malnutrition

Both the number of people affected by malnutrition and highest prevalence of wasting occur in lower-middle-income countries

Aetiology

  • Lack of access
  • Poor feeding practices
  • Infection

Clinical presentation

Kwashiorkor - protein energy malnutrition from only having carbs resulting in oedema
notion image
Marasmus - characterized by energy deficiency resulting in low body weight

Investigations

Diagnosis of severe acute malnutrition (kwashiorkor or marasmus)

  • Mid-arm circumference <115mm
  • Weight for height under 3SD
  • Oedema of both feet

Management

Criteria for inpatient or outpatient care

  • Children who are identified as having severe acute malnutrition should first be assessed with a full clinical examination to confirm whether they have medical complications and whether they have an appetite
  • Children who have appetite and are clinically well and alert should be treated as outpatients
    • Investigate cause
    • Vitamin A
    • De-worm
    • Ready to use therapeutic food (RUTF) - peanut butter, dried milk, vitamins and minerals
    • Check vaccinations
  • Children who have medical complications, severe oedema, or poor appetite or present with one or more danger signs should be treated as inpatients (as below)

Inpatient management

  • Management is the same for kwashiorkor and marasmus
  • Involves 10 steps in 2 phases - initial stabilisation and rehabilitation

  • All severely malnourished children are at risk of hypoglycaemia - give a feed or 10% glucose/sucrose immediately on admission
  • All children with hypothermia should be treated routinely for hypoglycaemia and infection
  • Dehydration tends to be overdiagnosed - do not use IV route for rehydration except in shock, rehydrate slowly (orally or NG tube) with a special rehydration solution for malnutrition ReSoMal (ORS not suitable for severely malnourished children)
  • Early iron aggregates infection so avoided until rehabilitation phase
  • Keep breastfeeding if able but also initiate feeding with F75 milk then catch up with F100
