Inflammation Markers and Major Depressive Disorder in Patients With Chronic Heart Failure: Results From the Sertraline Against Depression and Heart Disease in Chronic Heart Failure Study.

ABSTRACT: Major depressive disorder (MDD) and chronic heart failure (CHF) have in common heightening states of inflammation, manifested by elevated inflammation markers such as C-reactive protein. This study compared inflammatory biomarker profiles in patients with CHF and MDD to those without MDD.The study recruited patients admitted to inpatient care for acute heart failure exacerbations, after psychiatric diagnostic interview. Patients with Beck Depression Inventory (BDI) scores lower than 10 and with no history of depression served as the nondepressed reference group (n = 25). MDD severity was defined as follows: mild (BDI 10-15; n = 48), moderate (BDI 16-23; n = 51), and severe (BDI ? 24; n = 33). A Bio-Plex assay measured 18 inflammation markers. Ordinal logistic models were used to examine the association of MDD severity and biomarker levels.Adjusting for age, sex, statin use, body mass index, left ventricular ejection fraction, tobacco use, and New York Heart Association class, the MDD overall group variable was significantly associated with elevated interleukin (IL)-2 (p = .019), IL-4 (p = .020), IL-6 (p = .026), interferon-? (p = .010), monocyte chemoattractant protein 1 (p = .002), macrophage inflammatory protein 1? (p = .003), and tumor necrosis factor ? (p = .004). MDD severity subgroups had a greater probability of elevated IL-6, IL-8, interferon-?, monocyte chemoattractant protein 1, macrophage inflammatory protein 1?, and tumor necrosis factor ? compared with nondepressed group. The nondepressed group had greater probability of elevated IL-17 (p < .001) and IL-1? (p < .01).MDD in patients with CHF was associated with altered inflammation marker levels compared with patients with CHF who had no depression. Whether effective depression treatment will normalize the altered inflammation marker levels requires further study.ClinicalTrials.gov NCT00078286.

Project description:Background: Major Depressive Disorder (MDD) is a moderately heritable disorder with a high lifetime prevalence. At present, laboratory blood tests to support MDD diagnosis are not available. Methods: We used a classifier approach on blood gene expression profiles of a unique set of non-medicated subjects (MDD patients and controls) to select genes of which expression is predictive for disease status. To reveal blood gene expression changes related to MDD disease, we applied a powerful ex vivo stimulus to the blood, i.e. incubation with lipopolysaccharide (LPS; 10 ng/ml blood). Results: Based on LPS-stimulated blood gene expression using whole-genome microarrays in 42 subjects (primary cohort; 21 MDD patients (mean age 42.3 years), 21 healthy controls (mean age 41.9 years)), we identified a set of genes (CAPRIN1, CLEC4A, KRT23, MLC1, PLSCR1, PROK2, ZBTB16) that serves as a molecular signature of MDD. These findings were validated for the primary cohort using an independent quantitative PCR method (P = 0.007). The difference between depressive patients and controls was confirmed (P = 0.019) in a replication cohort of 13 patients with MDD (mean age 42.8 years) and 14 controls (mean age 45.6 years). The MDD-signature score comprised of expression levels of 7 genes could discriminate depressive patients from controls with sensitivity of 76.9% and specificity of 71.8%. Conclusions: We show for the first time that molecular analysis of stimulated blood cells can be used as an endophenotype for MDD diagnosis, which is a milestone in establishing biomarkers for neuropsychiatric disorders with moderate heritability in general. Our results may provide a new entry point for following and predicting treatment outcome, as well as prediction of severity and recurrence of MDD. In total, 33 MDD patients and 34 healthy controls were analyzed using basal gene expression in whole blood, and gene expression from whole blood that was stimulated with LPS for 5-6 h, using microarrays. Patients were arbitrarily selected from all patients to serve as primary cohort (nMDD = 21 (MDD01-MDD21); nControls = 21 (Con01-Con21)), or replication cohort (nMDD = 12 (MDD22-MDD35); nControls = 13 (Con22-Con37)) using microarrays. This submission does not include Samples CON21_LPS or CON30_LPS.
