Abstract

It is currently unknown whether elevated cytokine levels in depression are confined to any specific subgroup of depressive patients. In this study, medical out-patients presenting with cardiovascular risk factors (N = 356) were assessed for both cognitive-affective and physical symptoms of depression using the Hospital Anxiety and Depression Scale (HADS) and the Maastricht questionnaire (MQ), respectively. In study participants assigned to the highest (?21) and lowest (?5) quartile for the MQ score, serum levels of cytokines were measured. We found highly significant associations between cognitive-affective symptoms of depression and elevated serum levels of interleukin-6 (IL-6; ? = .231; p = .002) and interleukin-10 (IL-10; ? = .370; p <.001), respectively. In multiple regression models elevated IL-10 serum concentration was independently related to cognitive-affective symptoms of depression (? = .165; p = .002). When all cytokines were included in one model, elevated IL-10 serum concentrations remained a significant predictor for depressive mood (? = .157; p = .009). In patients with cardiovascular risk factors and extreme scores for vital exhaustion, elevated serum IL-6 and even more IL-10 concentrations are linked to the presence of depressive mood. Future studies will have to test whether the so far unreported association of IL-10 with depressive mood represents a causal pathway involved in the pathogenesis or in the prognostic effect of depressive mood in cardiac patients.
