title: T-lymphocyte cholecystokinin-8 and beta-endorphin concentrations in eating disorders: I. Anorexia nervosa.
abstract: Baseline concentrations of cholecystokinin-8 (CCK-8) and beta-endorphin (beta-EP) were measured in T-lymphocytes from 33 restricting patients with anorexia nervosa (AN-R), 23 binging/purging patients with anorexia nervosa (AN-BP), and 24 healthy volunteers. CCK-8 basal values were significantly lower and beta-EP values significantly higher in AN-R and AN-BP patients than in normal volunteers. Levels of the peptides were measured three more times during a 4-month combined cognitive-behavioral/psychopharmacological treatment (nortriptyline or fluoxetine in AN-R, fluoxetine or amineptine in AN-BP). CCK-8 values fluctuated (nonsignificantly) during each treatment, while beta-EP values decreased (to a significant degree only in fluoxetine-treated AN-R patients).
