Abstract
BACKGROUND: Although accumulating evidence has shown increased cortisol levels in serum, saliva, or 24-h urine samples in depression, a number of studies did not find the association between cortisol levels and depression. Hair cortisol levels reflect long-term and historical information of cortisol and hair cortisol analysis has been applied in the research of psychiatric diseases. The aim of this study is to compare the hair cortisol levels between patients with depression and healthy controls. METHODS: Hair cortisol levels of 22 first-episodic and 13 recurrent female patients with depression and 30 healthy controls were measured and compared using the electrochemiluminescence immunoassay. The relationship between hair cortisol levels and Hamilton depression scale (HAMD) or Hamilton anxiety scale (HAMA) scores were also examined. RESULTS: Before disease episode, no significant differences were observed among healthy controls, first-episodic patients and recurrent patients. In disease episode, the hair cortisol level in first-episodic patients was significantly higher than that in healthy controls or recurrent patients, while no significant difference was observed between recurrent patients and healthy controls. No significant correlation was found between HAMD or HAMA scores and hair cortisol levels in patients. LIMITATIONS: First, long-term effects of antidepressants on the results cannot be excluded without detailed medication information of the recurrent patients. Second, sample sizes might be relatively small. CONCLUSIONS: Our results indicate that hair cortisol levels increased in disease episode in first-episodic, but not recurrent patients with depression, which may suggest that episodes of disease have influence on cortisol levels.
