SYNOPSISWe studied the effect of acute tryptophan (TRP) depletion in a group of eight abstinent bulimic (BN) subjects and in 12 healthy female controls. Despite being free of episodes of bingeeating and vomiting for a prolonged period, the abstinent BN subjects still appeared to practice dietary restraint as judged by their food intake in a test meal. In addition, their plasma TRP concentrations were significantly lower than those of the controls. Administration of a TRP-free amino acid load (52 g) significantly lowered plasma total and free TRP. However, compared to a balanced amino acid load, this procedure did not have significant effects on mood, appetite or food intake in either the abstinent BN subjects or the healthy controls.

BackgroundLow serotonin transmission is thought to increase susceptibility to a wide range of substance use disorders and impulsive traits.AimsTo investigate the effects of lowered serotonin on cocaine-induced (1.0 mg/kg cocaine, self-administered intranasally) dopamine responses and drug craving.MethodIn non-dependent cocaine users, serotonin transmission was reduced using the acute tryptophan depletion method. Striatal dopamine responses were measured using positron emission tomography with [11C]raclopride.ResultsAcute tryptophan depletion increased drug craving and striatal dopamine responses to cocaine. These acute tryptophan depletion-induced increases did not occur in the absence of cocaine.ConclusionsThe results suggest that low serotonin transmission can increase dopaminergic and appetitive responses to cocaine. These findings might identify a mechanism by which individuals with low serotonin are at elevated risk for both substance use disorders and comorbid conditions.
