title: The role of depression and childhood trauma on cortisol suppression in women with bulimia nervosa: a pilot study.
abstract: OBJECTIVE
  Although some studies have shown cortisol nonsuppression following dexamethasone suppression test (DST) in current bulimia nervosa (BN), no study has looked at HPA axis abnormalities in behaviorally recovered BN patients. The purpose of this pilot study is to explore the role of current vs behaviorally recovered BN, as well as depression and childhood trauma in cortisol suppression in BN.
  
  
  METHODS
  A 0.5 mg DST was performed on 21 patients with behaviorally recovered BN, 9 women with current BN and 14 controls. BN group also completed the Hamilton Depression Rating Scale and Childhood Trauma Questionnaire.
  
  
  RESULTS
  There were no differences between the three groups in cortisol suppression, and BMI was not associated with cortisol levels following DST. Within the BN group, depression was significantly associated with afternoon cortisol nonsuppression (p=0.005).
  
  
  CONCLUSIONS
  As researchers look for more accurate ways to identify biological phenotypes of BN, presence of comorbid depression may help explain differences in cortisol suppression.
