The effect of DPT inoculation on the hormonal control of glucose homeostasis in children recovered from malnutrition.
The effect of a controlled stress (DPT inoculation) on the hormonal control of glucose homeostasis was investigated in children nutritionally rehabilitated from severe malnutrition. The age range of the 15 children studied was 6-26 months. Plasma insulin (INS), growth hormone (GH) and interleukin-1 (IL-1) were measured by radioimmunoassay; plasma glucose (GLU) by a glucose oxidase method; and red cell insulin binding (%SB) was determined, using A-14 monoiodinated insulin. Measurements were made on two occasions: (T-0) at 10 a.m., 12 hr before DPT inoculation, and (T-36) 36 hr. after inoculation. On both occasions, 4 hr post-prandial blood samples were used, and the mean body temperature (T) on the day of the test was determined. Red cell insulin binding (%SB) was significantly higher at T-36 than at T-0 (16.8 +/- 1.7 vs 12.1 +/- 1.2 (14), p = 0.005). (Results were expressed as mean +/- SEM, numbers of paired observations in parentheses). The higher %SB after DPT was accompanied by an increase in the number of receptor sites (S) (29.05 +/- 6.5 vs 15.6 +/- 2.5 (14), p = 0.025). However, insulin receptor affinity (K x 10(9) M-1) was decreased (0.7 +/- 0.1 vs 1.5 +/- 0.3 (14), p = 0.008). There were no significant differences in the plasma levels of insulin, glucose and interleukin-1, but plasma growth hormone (microU/ml) was increased after DPT, (18.0 +/- 3.0 vs. 11.5 +/- 1.2 (13), p = 0.04). Body temperature (degree C) was also significantly increased after DPT, (99.6 +/- 0.4 vs. 98.3 +/- 0.2 (14), p = 0.006).(ABSTRACT TRUNCATED AT 250 WORDS)
