BACKGROUND: Increased central serotonin (5-HT) function has been hypothesised to be a vulnerability trait in anorexia nervosa.
METHODS: Eighteen women with a history of DSM-III-R anorexia nervosa and 18 female controls were examined. The subjects had recovered weight and menstrual function. A placebo-controlled d-fenfluramine test was used. Subjects ingested d-fenfluramine or placebo and after three hours were offered a 'free' meal. The amounts eaten were recorded and plasma cortisol and prolactin levels were measured. Questionnaires related to eating attitudes and behaviour, to personality, and to mood were administered.
RESULTS: Unlike the control subjects, those recovered from anorexia nervosa did not show the expected appetite-suppressing responses to d-fenfluramine; their eating attitudes and behaviour were more restrained, 'negative' perfectionism was more pronounced, and post-meal plasma cortisol levels did not rise as expected.
CONCLUSIONS: Our results do not suggest that increased central 5-HT function is a trait marker in anorexia nervosa, but dysregulation in part of the central 5-HT system may be a vulnerability factor. The flattened post-meal response to cortisol in the subjects who had recovered from anorexia nervosa suggests that their hypothalamic pituitary--adrenal axis may be altered and deserves further investigation.
