Abstract

Cortisol (F) and dehydroepiandrosterone (DHA) were measured following each 5 kg gain in weight in a group of 16 patients with anorexia nervosa admitted to hospital for refeeding. The mean percentage of standard weight on admission was 65% and that on discharge was 92%. Basal plasma cortisol fell gradually throughout the inpatient period, the correlation coefficient of the regression line relating percentage of standard weight to plasma cortisol in all patients was -0.559 (p less than 0.001). Adrenal androgen production, however, increased with weight gain and the correlation coefficient of the regression line of androgen production against percentage of standard weight was +0.303 (p less than 0.01). The DHA/F ratio increased with weight gain. This suggests that weight gain in the patient with anorexia nervosa could be associated with increased activity in the adrenal 17,20-lyase enzymes and a decrease in the activity of the 3-beta hydroxysteroid dehydrogenase. The possibility that these adrenal enzyme changes are controlled by pituitary proopiocortin peptides [the putative cortical androgen stimulating hormone (CASH)] is discussed as is the relationship between normal adrenarche and the weight related changes in adrenal function in anorexia nervosa.
