title: Immunoendocrine aspects of anorexia nervosa.
abstract: The T-lymphocyte proliferative response to phytohemoagglutinin (PHA) stimulation was the same in 11 anorexic women, 6 restricted (AN-R) and 5 bulimic (AN-B), and in 11 sex- and age-matched controls, in basal conditions and after acute administration of corticotropin-releasing hormone (CRH). Basal plasma levels of ACTH and cortisol were higher in patients than in controls, while beta-endorphin (beta-EP), growth hormone (GH) and prolactin (PRL) concentrations did not differ in the two groups. ACTH and beta-EP responses to CRH stimulation were blunted in patients, while those of cortisol did not differ in the two groups. ACTH, beta-EP and cortisol responses to the dexamethasone suppression test were impaired in 55% of the patients. Baseline T-lymphocyte concentrations of cholecystokinin-8 (CCK-8) and beta-EP were measured in another group of 56 anorexics, 33 restricted and 23 bulimic, and in 24 controls. CCK-8 values were significantly lower and beta-EP values significantly higher in patients than in controls.
