In seventy-two patients affected by hyperphagic obesity and forty age-matched, normal weight volunteers we performed a psychological assessment, through various mental tests, and evaluated the beta-endorphin (B-Ep), ACTH and cortisol circulating levels, in basal condition and following an overnight short dexamethasone suppression test (DST). The hormones were measured by radioimmunoassay either directly in the serum (cortisol) and the plasma (ACTH), or after affinity gel column chromatography (B-Ep). In obese subjects B-Ep levels in basal conditions were four times greater than in normal weight controls and showed significantly less reduction after DST. ACTH and cortisol levels, in contrast, were in the normal range and were suppressed following dexamethasone as was also true in the control group. Psychological evaluation on M.M.P.I. (Minnesota Multiphasic Personality Inventory) revealed a trend toward hypochondria, depression, hysterias, psychoasthenia and schizophrenia. However, no significant correlation has been found between M.M.P.I. clinical scale scores and circulating levels of B-Ep and cortisol either in basal conditions or after DST. In conclusion, these data do not support the hypothesis that abnormalities of the hypothalamus-pituitary-adrenal axis in hyperphagic obesity are related to affective disorders.

Circulating levels of cortisol and beta-endorphin were evaluated in basal condition and following dexamethasone administration in 20 healthy subjects and in 60 subjects suffering from hyperphagic obesity. Moreover, mental tests were administered to these subjects in order to evaluate the affective state. Our data showed that in obese patients B-Ep plasma levels were significantly higher than those of the control group, while cortisol plasma levels were similar in the two groups. Dexamethasone administration decreased cortisol plasma levels in normal and obese subjects, while did not modify B-Ep plasma levels in obese subjects. However, after dexamethasone administration 16.6% of the obese subjects did not show a complete decrease of cortisol level. This group of subjects obtained the highest scores for depression and hypochondria to MMPI.
