Summary

Recent studies have examined the effectiveness of the dexamethasone suppression test (DST) in the evaluation of bulimia. In a series of 18 female bulimic outpatients without major depression, 9 (50%) failed to suppress on the DST. No significant difference was found between suppressors and nonsuppressors in personal and family histories of affective disorder, levels of anxious and depressive symptoms, psychoactive substance abuse, and severity of abnormal eating-related behaviours. In contrast, non-suppression was significantly associated with low weight. There is a trend to differentiate non-suppressors from suppressors in the current diagnosis of anorexia nervosa and in past history of anorexia nervosa. Seven patients received fluvoxamine for 8 weeks. Five patients were suppressors and showed a significant decrease in the frequency of their binges while the 2 non-suppressors did not improve. These preliminary results suggest that DST non-suppression might be typical of bulimic patients with anorexia nervosa and that pretreatment DST results might predict the response of bulimic behaviour to treatment with fluvoxamine.
