OBJECTIVE:Patients with anorexia nervosa (AN) have disturbances of appetite and behaviors, such as dysphoria, inhibition, and obsessions, that could be related to altered serotonin activity. To investigate such relationships, we administered meta-chlorophenylpiperazine (m-CPP), a relatively serotonin-specific drug. METHODS: To avoid the confounding effects of malnutrition or weight loss, we studied 12 patients with restricting-type AN between 5 and 17 days after a return to a normal weight and while on a stable dietary intake. We compared them to 12 healthy control women (CW). m-CPP was administered double blind and placebo controlled. RESULTS: Although weight restored, AN women had lower body weight and increased ratings for depression and obsessionality compared with CW. After m-CPP, AN women had an elevation in mood and a reduction in body image distortion when compared with placebo. After m-CPP, groups had similar cortisol, adrenocorticotropin (ACTH), and growth hormone responses whereas AN women had an uncertain reduction in prolactin response. DISCUSSION: These data support other studies that suggest that altered serotonin activity persists after weight restoration in AN patients. The finding that m-CPP temporarily improved mood and reduced body image distortions supports the hypothesis that altered serotonin activity may contribute to the pathophysiology of AN.
