Blood Plasma Levels of Cortisol, Insulin, Growth Hormone and Somatomedin in Children with Marasmus, Kwashiorkor, and Intermediate Forms of Protein-Energy Malnutrition (41222)

Plasma insulin, growth hormone, somatomedin, free and bound cortisol, and serum albumin were measured in human infants with protein-energy malnutrition and in age-matched control subjects. Insulin and somatomedin were reduced, growth hormone and free and total cortisol were elevated in malnourished infants. Free cortisol and somatomedin were negatively correlated (r = −0.78) and somatomedin and percentage weight deficit were negatively correlated in marasmus (r = −0.62) and kwashiorkor (r = −0.68). It is suggested that elevated plasma-free cortisol as well as depressed plasma insulin in protein-energy malnourished infants is partially responsible for the depressed plasma somatomedin and reduced protein synthesis and growth in children. © 1981, SAGE Publications.
