GH, ACTH, LH and FSH behaviour in the first seven days of life.

--43 neonates, born vaginally after spontaneous labor between the 38th and the 42nd week of pregnancy, were examined. GH and ACTH levels were assayed in 14 newborn infants. LH and FSH were determined in the remaining 29 patients (16 boys and 13 girls). Samples were collected from all infants for the assay of the above mentioned hormones at the 2nd, 6th, 12th and 24th hour of life, then every day for 7 consecutive days. During the whole first week of life plasma GH gave values that were significantly higher than those found in subjects over four years of age. The highest mean value of plasma ACTH was found at the 2nd hour of life (162.2 +/- 34.1 pg/ml). Then, there is a significant fall in the hormone level beginning with the 12th hour (p less than 0.01). Minimum level was reached on the 7th day. Plasma hCG-LH presents its maximum mean value at the 2nd hour, both in boys and girls (48.5 +/- 16.2 and 33.0 +/- 24.9 mU/ML, respectively). after this, plasma hCG-LH decreases progressively. No significant differences between the two sexes were found. Even though the mean values of plasma FSH do not change significantly during the whole test period, they do demonstrate a sex difference (significantly higher values in the females) from the fifth day afterwards.

GH, ACTH, TSH, LH, and FSH reserve in pre pubertal girls with congenital adrenal hyperplasia.

The pituitary reserve of GH, ACTH, TSH, LH, and FSH was determined in seven prepubertal birls suffering from congenital adrenal hyperplasia due to 21-hydroxylation defect and under treatment with cortisone acetate. GH and ACTH were studied during the insulin induced hypoglycemia test. The LH, FSH, and TSH reserved were assayed by means of the LH-RH and TRH tests. GH behavior proved to be similar to that found in normal subjects, whereas basal and/or after stimulus ACTH turned out to be higher than the upper limits of the normal range in five out of six girls. The mean basal value and the mean LH peak were not significantly higher than those found in normal prepubertal girls; the mean basal value and the mean FSH peak were lower than the mean of the control group. The difference is significant (P less than 0.05) only between the peak values. The mean basal TSH in the patients is significantly higher (P less than 0.01) than the mean value of the control group. The maximum TSH after TRH is not significantly different from the mean value fo the control group.

Relationships among the secretion of ACTH, GH, and cortisol during the insulin-induced hypoglycemia test in the normal and obese child.

The behavior of the secretion of ACTH, GH, and plasma cortisol during the insulin-induced hypoglycemia test on normal and obese children was studied. The secretion of the above-mentioned hormones was determined by calculating the integrals of the curves. The mean values of the integrals of the plasma cortisol and ACTH curves do not show any significant differences between the two groups of children. The mean values of the ratios between the integrals of the plasma cortisol and ACTH curves show a significant difference between the two groups (P smaller than 0.01). Since the mean values of the integrals of the plasma cortisol curves are practically the same in both groups, the difference in the above-mentioned ratios refers to the lower values of the integrals of the ACTH curves found in the obese children. This enables us to make the hypothesis that in the obese child the function of the pituitary-adrenal axis, at least during the insulin test, does not differ from the norm thanks to the adaptation of the ACTH secretion to the greater sensitivity of the adrenal glands to this hormone. In both the groups examined there was no correlation between the secretion of ACTH and plasma cortisol, between ACTH and GH, and between plasma cortisol and GH.
