A comparison of fasting plasma insulin and growth hormone concentrations in marasmic, kwashiorkor, marasmic-kwashiorkor and underweight children

Abstract

Fasting plasma insulin and growth hormone concentrations were measured in 24 marasmic, 11 kwashiorkor, 16 marasmic-kwashiorkor, and 4 underweight children. Hormone measurements were made by a special modification of the Hales and Randle double antibody immunoassay with increased sensitivity in the concentration range 0-25 micronU/ml. Fasting plasma insulin was low in marasmus, kwashiorkor, and marasmic-kwashiorkor children, and increased to normal levels after recovery. Fasting plasma growth hormone was elevated in all groups during malnutrition and was significantly decreased to normal levels after recovery. There were no significant differences in plasma insulin or growth hormone levels between the different clinical types of severe protein energy malnutrition. These hormonal changes in severe protein energy malnutrition are of complex and not fully understood etiology. However, recovered children appear to have a hormonal pattern similar to that described in normal control infants and children.
