Abstract

Background: Catecholamines are thought to play a significant role in the pathophysiology of posttraumatic stress disorder (PTSD), but findings in PTSD have been discrepant. Methods: To obtain more information about catecholamine activity in PTSD, we sampled plasma norepinephrine(NE) and 3-methoxy-4-hydroxyphenylglycol (MHPG) concentrations over a24-hour period in men with PTSD (n = 15) and major depressive disorder (MDD) (n = 12), and nonpsychiatric comparison subjects (n = 13), under unstimulated conditions. Chronobiological analyses were performed to determine possible changes in the circadian and ultradian release ofthese hormones. Results: Significant group differences were present for mean plasma NE levels (p = .03), but not MHPG. NE levels were significantly associated with severity of depression in the PTSD group (p =.002). Therefore, PTSD subjects were further subdivided into those with and without a comorbid secondary depression. Increased NE levels were only present in PTSD subjects who did not have a secondary depression. This study also found no significant group differences on any of the chronobiological parameters. Conclusions: The results clarify that increased NE levels in PTSD may be confined to the subgroup of subjects who do not have comorbid depression, and as such, may help resolve some of the discrepancies in the literature regarding basal catecholamine activity.
