- Abstract
Objectives Late-life depression may be associated with vascular disease. The purpose of the study was to investigate this association by determining the levels of soluble adhesion molecules (sICAM-1 and sVCAM-1) which represent markers of ischemia-induced inflammation in elderly individuals with depression. Methods Blood samples were obtained from 33 subjects with depression selected from a community-dwelling population after screening with the Geriatric Depression Scale, and 33 matched controls. Serum concentrations of sICAM-1 (ng/mL) and sVCAM-1 (ng/mL) were measured in both groups. Results Depressed patients (Group A) possessed significantly higher sICAM-1 levels compared to healthy controls (Group B) (674.94 ± 166.90 ng/ml vs 467.05 ± 231.26 ng/ml, respectively, p < 0.01). Similarly the same groups demonstrated elevated sVCAM-1 levels compared to controls (572.14 ± 182.20 ng/ml vs 449.04 ± 285.27 ng/ml, p < 0.05); a difference that in both cases remained significant after adjustment for potential confounders (gender, smoking, presence of metabolic syndrome). Conclusion These findings indicate an association between high serum levels of VCAM-1, and ICAM-1 and depression in the elderly and further support the vascular depression hypothesis, which has important implications for the understanding and management of late-life depression.
