Dehydroepiandrosterone-sulfate/cortisol ratio in panic disorder

Abstract

We hypothesized that the dehydroepiandrosterone-sulfate (DHEA-S)/cortisol ratio, which has been used as an index of adrenocortical function, would be altered in panic disorder patients and would change after treatment. We evaluated 10 male and 14 female outpatients meeting DSM-III-R criteria for panic disorder. Of these 24 subjects, 13 were treated with clonazepam, 8 were treated with alprazolam, and 3 were treated with placebo as part of a double-blind study. The DHEA-S/cortisol ratio values in the 24 patients with panic disorder (mean = 20.5, SD = 11.6) were significantly higher than those of a group of 60 normal controls (mean = 11.5, SD = 6.01) and were also significantly higher than those of a group of 22 depressed patients (mean = 10.6, SD = 6.33). Although there was no significant difference in the pretreatment DHEA-S/cortisol ratio values between male (mean = 23.6, SD = 11.8) and female (mean = 18.2, SD = 11.3) panic disorder patients, the effects of treatment on this ratio differed between the two sexes. In fact, in the female patients there was a significant decrease in the DHEA-S/cortisol ratio at the end of the study (mean = 15.1, SD = 7.9), while in the male patients there was no significant change in this ratio at the end of the study (mean = 30.2, SD = 21.4). No significant differences were noted between pretreatment and posttreatment DHEA-S/cortisol ratio values in patients treated with alprazolam (n = 8), in patients treated with clonazepam (n = 13), or in patients treated with placebo (n = 3).(ABSTRACT TRUNCATED AT 250 WORDS)
