Objective-Major depressive disorder (MDD) is associated with immune system dysfunction and disruption of multiple circadian systems. Adiponectin is an adipocytokine with antiinflammatory and anti-atherogenic effects. Circulating concentrations are inversely related to adiposity and risks of metabolic syndrome and diabetes mellitus. Our goals were to: A) establish whether premenopausal women with MDD exhibit decreased plasma adiponectin concentrations and/or disruption of circadian adiponectin

Method-Case-control study of community-dwelling premenopausal women with MDD and ageand BMI-matched-control subjects (N=23/group). Main outcome measures were circulating concentrations of adiponectin, leptin, ACTH, and cortisol measured hourly for 24h. Results-Women with MDD had approximately 30% lower mean 24h concentrations of adiponectin than did control subjects. Adiponectin was inversely related to depression severity and total duration of disease, suggesting a causal link. In contrast, nocturnal leptin concentrations were higher in the MDD versus control groups. Leptin was inversely related to cortisol and adiponectin both in subjects with depression and in control subjects. In cross-correlation analyses, the Manuscript relationship between ACTH and cortisol was stronger in women with MDD than in control subjects, consistent with HPA-axis activation in MDD. Conclusions-Reduced daily adiponectin production may increase the risk of diabetes mellitus, and elevated leptin may contribute to osteoporosis, in premenopausal women with MDD.
