Recent reports have suggested that normal-weight bulimic patients without clinical evidence of major depressive disorder will have an abnormal response to dexamethasone. Of 23 normal-weight bulimic patients without clinical evidence of major depressive disorder, 11 had abnormal results on their dexamethasone suppression tests (DSTs). This finding closely matches those of other reports. After successful treatment with desipramine, repeat DSTs showed conversion to normal suppression in 6 of the 7 patients tested. Pretreatment DST results failed to predict the response to medication. The striking similarity of these findings to those reported in patients with major depression suggests that bulimia may be a consequence or an equivalent of major affective disorder.
