Protein-calorie malnutrition: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Both kwashiorkor (edematous PCM) and marasmus (nonedematous PCM) are common in underdeveloped countries and in areas in which dietary amino acid content is insufficient to satisfy growth requirements. Kwashiorkor typically occurs at about age 1, after infants are weaned from breast milk to a protein-deficient diet of starchy gruels or sugar water, but it can develop at any time during the formative years. Marasmus affects infants ages 6 to 18 months as a result of breast-feeding failure, or a debilitating condition such as chronic diarrhea.

In industrialized countries, PCM may occur secondary to chronic metabolic disease that decreases protein and calorie intake or absorption, or trauma that increases protein and calorie requirements. In the United States, PCM is estimated to occur to some extent in 50% of elderly people in nursing homes. Those who aren’t allowed anything by mouth for an extended period are at high risk of developing PCM. Conditions that increase protein-calorie requirements include severe burns and injuries, systemic infections, and cancer (accounts for the largest group of hospitalized patients with PCM). Conditions that cause defective utilization of nutrients include malabsorption syndrome, short-bowel syndrome, and Crohn’s disease.

Protein-calorie malnutrition: Causes
(Handbook of Diseases)

Both marasmus (nonedematous protein-calorie malnutrition) and kwashiorkor (edematous protein-calorie malnutrition) are common in underdeveloped countries and in areas where dietary amino acid content is insufficient to satisfy growth requirements. Kwashiorkor typically occurs at about age 1, after infants are weaned from breast milk to a protein-deficient diet of starchy gruels or sugar water, but it can develop at any time during the formative years. Marasmus affects infants ages 6 to 18 months as a result of breast-feeding failure or a debilitating condition such as chronic diarrhea.

In industrialized countries, protein-calorie malnutrition may occur secondary to chronic metabolic disease that decreases protein and calorie intake or absorption or trauma that increases protein and calorie requirements. In the United States, protein-calorie malnutrition is estimated to occur to some extent in 50% of surgical and 48% of medical patients. Those who aren’t allowed anything by mouth for an extended period are at high risk for developing protein-calorie malnutrition. Conditions that increase protein-calorie requirements include severe burns and injuries, systemic infections, and cancer (accounts for the largest group of hospitalized patients with protein-calorie malnutrition.) Conditions that cause defective utilization of nutrients include malabsorption syndrome, short-bowel syndrome, and Crohn’s disease.

Kwashiorkor: Kwashiorkor - etiology
(The 5-Minute Pediatric Consult)

  • Children have relatively high energy and protein requirements per kilogram of body weight.
  • Inappropriate use of infant formula or the introduction of bulky carbohydrate-based staple foods which are low in energy density, protein and fat content may lead to PEM.
  • Food scarcity from drought or other natural disasters, war or civil disturbance may lead to PEM.
  • Aflatoxin poisoning from the fungus Aspergillus flavus has been implicated in the etiology of Kwashiorkor. Aflatoxin concentration has been found to be elevated in the blood and liver of children with Kwashiorkor. Aflatoxins may appear in breast milk.
  • Further investigations have shown an association between selenium deficiency and congestive heart failure in Kwashiorkor.

Kwashiorkor - etiology_pathophysiology of-pem-by-systems

  • Temperature regulation is impaired, leading to hypothermia in a cold environment and hyperthermia in a hot environment.
  • Fluid and electrolytes:
    • Increase in total-body sodium and decrease in total-body potassium
    • Increased cell membrane permeability in Kwashiorkor leads to increased intracellular sodium and decreased intracellular potassium.
    • Increased intracellular sodium is accompanied by increased cellular water.
  • Hypophosphatemia is associated with malnutrition and results in high mortality.
  • Liver:
    • Protein synthesis is reduced; particularly albumin, transferrin and apolipoprotein B.
    • Hypoalbuminemia reduces colloid osmotic pressure, leading to edema.
    • Hypertriglyceridemia leads to fatty infiltration of the liver.
  • Gluconeogenesis is reduced which increases risk of hypoglycemia during infection.
  • Cardiovascular system:
    • Pericardial effusion may be present in Kwashiorkor.
    • Reduced cardiac output leads to compromised tissue perfusion and a reduction in renal blood flow and glomerular filtration rate.
    • Increase in ferritin stimulates release of antidiuretic hormone and subsequent fluid retention.
  • Respiratory system:
    • Reduced muscle mass affects respiratory muscles, such as the diaphragm, and reduces pulmonary function.
    • Respiratory muscle weakness may be exacerbated by hypophosphatemia and hypokalemia.
  • GI system:
    • Reduction of gastric acid, intestinal motility and pancreatic digestive enzymes
    • Intestinal mucosa is atrophied resulting in malabsorption
  • Endocrine system:
    • Insulin secretion is reduced.
    • Growth hormone secretion is increased while somatomedin activity is reduced.
    • Glucagon, epinephrine and cortisol levels are increased.
    • Increased epinephrine, growth hormone and corticosteroids leads to lipolysis, an increase in free fatty acid concentration and increased peripheral insulin resistance.
  • Immune system:
    • All aspects of immune function are deminished in malnutrition.
