Cortisol Awakening Reaction and Anxiety in Depressed Coronary Artery Disease Patients.

ABSTRACT: Disturbances of HPA axis functioning as represented by cortisol awakening reaction (CAR) belong to the mediating pathways linking psychosocial distress and cardiovascular risk. Both depression and anxiety have been confirmed as independent risk factors for coronary artery disease (CAD). However, data on anxiety and cortisol output in CAD patients are scarce. Based on previous data, we hypothesized that anxiety would be associated with higher cortisol output and a more pronounced morning increase in moderately depressed CAD patients. 77 patients (60 y, 79% male) underwent saliva sampling (+0, +30, +45, +60 min after awakening, midday and late-night sample). Anxiety was measured using the Hospital Anxiety and Depression Scale (HADS) and patients were grouped into anxious versus non anxious subjects based upon the recommended score (≥11). A repeated measures ANOVA yielded a significant time and quadratic time effect referring to the typical CAR. Anxious patients showed a significantly steeper 30 min increase, higher AUCi, lower waking and late-night cortisol levels. The steeper cortisol increase in the anxious group is in line with previous data and may be interpreted as a biological substrate of affect regulation. The lower basal and late-night levels coupled with greater AUCi mirror a more dynamic reactivity pattern compared to depressed subjects without anxiety.

Project description:BackgroundAnxiety disorders are prevalent and associated with poor prognosis in patients with coronary artery disease (CAD). However, studies examining screening of anxiety disorders in CAD patients are lacking. In the present study we evaluated the prevalence of anxiety disorders in patients with CAD and diagnostic utility of self-rating scales for screening of anxiety disorders.MethodsFive-hundred and twenty-three CAD patients not receiving psychotropic treatments at initiation of rehabilitation program completed self-rating scales (Hospital Anxiety and Depression Scale or HADS; Spielberger State-Anxiety Inventory or SSAI; and Spielberger Trait-Anxiety Inventory or STAI) and were interviewed for generalized anxiety disorder (GAD), social phobia, panic disorder and agoraphobia (Mini-International Neuropsychiatric Interview or MINI).ResultsThirty-eight (7%) patients were diagnosed with anxiety disorder(s), including GAD (5%), social phobia (2%), agoraphobia (1%) and panic disorder (1%). Areas under the ROC curve of the HADS Anxiety subscale (HADS-A), STAI and SSAI for screening of any anxiety disorder were .81, .80 and .72, respectively. Optimal cut-off values for screening of any anxiety disorders were ? 8 for the HADS-A (sensitivity = 82%; specificity = 76%; and positive predictive value (PPV) = 21%); ? 45 for the STAI (sensitivity = 89%; specificity = 56%; and PPV = 14%); and ? 40 for the SSAI (sensitivity = 84%; specificity = 55%; PPV = 13%). In a subgroup of patients (n = 340) scoring below the optimal major depressive disorder screening cut-off value of HADS-Depression subscale (score <5), the HADS-A, STAI and SSAI had moderate-high sensitivity (range from 69% to 89%) and low PPVs (? 22%) for GAD and any anxiety disorders.ConclusionsAnxiety disorders are prevalent in CAD patients but can be reliably identified using self-rating scales. Anxiety self-rating scales had comparable sensitivities but the HADS-A had greater specificity and PPV when compared to the STAI and SSAI for screening of anxiety disorders. However, false positive rates were high, suggesting that patients with positive screening results should undergo psychiatric interview prior to initiating treatment for anxiety disorders and that routine use of anxiety self-rating scales for screening purposes can increase healthcare costs. Anxiety screening has incremental value to depression screening for identifying anxiety disorders.

Project description:BackgroundPsychosocial stress and activation of neutrophil granulocytes are increasingly recognized as major risk factors of coronary artery disease (CAD), but the possible relationship of these two factors in CAD patients is largely unexplored. Activation of neutrophils was reported to be associated with stenting; however, the issue of neutrophil state in connection with percutaneous coronary intervention (PCI) is incompletely understood from the aspect of stress and its hypothalamic-pituitary-adrenal axis (HPA) background. Thus, we aimed to study cortisol- and ACTH-associated changes in granulocyte activation in patients undergoing PCI.Methodology/principal findingsBlood samples of 21 stable angina pectoris (SAP) and 20 acute coronary syndrome (ACS) patients were collected directly before (pre-PCI), after (post-PCI) and on the following day of PCI (1d-PCI). Granulocyte surface L-selectin, CD15 and (neutrophil-specific) lactoferrin were analysed by flow cytometry. Plasma cortisol, ACTH, and lactoferrin, IL-6 were also assayed. In both groups, pre- and post-PCI ratios of lactoferrin-bearing neutrophils were relatively high, these percentages decreased substantially next day; similarly, 1d-PCI plasma lactoferrin was about half of the post-PCI value (all p?0.0001). Post-PCI ACTH was reduced markedly next day, especially in ACS group (SAP: p<0.01, ACS: p?0.0001). In ACS, elevated pre-PCI cortisol decreased considerably a day after stenting (p<0.01); in pre-PCI samples, cortisol correlated with plasma lactoferrin (r?0.5, p<0.05). In 1d-PCI samples of both groups, ACTH showed negative associations with the ratio of lactoferrin-bearing neutrophils (SAP: r?=?-0.601, p<0.005; ACS: r?=?-0.541, p<0.05) and with plasma lactoferrin (SAP: r?=?-0.435, p<0.05; ACS: r?=?-0.609, p<0.005).Conclusions/significancePre- and post-PCI states were associated with increased percentage of activated/degranulated neutrophils indicated by elevated lactoferrin parameters, the 1d-PCI declines of which were associated with plasma ACTH in both groups. The correlation of plasma cortisol with plasma lactoferrin in the extremely stressed ACS before stenting, however, suggests an association of cortisol with neutrophil activation.

Project description:To date there is no clear explanation as to how Chlamydia pneumoniae heat shock protein 60 (cHSP60) gets activated either through TLR-2/4, MAPKinase (p38/JNK/ERK), apoptotic/antiapoptotic, chemokines and inflammatory cytokines pathways leading to coronary artery disease (CAD). Hence to better understanding towards cHSP60 signaling in CAD patients, we performed experiments at RNA levels in cHSP60 positive and negative groups of CAD patients. For the determination of positivity for C. pneumoniae, Helicobacter pylori, Cytomegalovirus and Herpes Simplex Virus in atheromatous plaque multiplex Real Time PCR was performed. Monoplex Real Time PCR was also performed with 16S rRNA and HSP60 gene Chlamydia pneumoniae. Further study was performed only on cHSP60 positive (negative for H. pylori, CMV & HSV-1) and cHSP60 negative (also negative for H. pylori, CMV & HSV-1) CAD patients. 1. Patients Forty patients (28 males, 12 females) in age group (51Â±13 year) attending Department of Cardio Thoracic & Vascular Surgery, Safdarjung Hospital, New Delhi from September 2007 to April 2008 were enrolled in the study. These patients had manifestations of CAD and were undergoing open by-pass heart surgery. Prior written consent was obtained from each patient. The study received clearance from Ethical committee, Safdarjung hospital. Patients who had a recent acute coronary syndrome or transient ischemic attack were not included in our study. 2. Atheroma collection and handling Atheromatous tissue were collected in aseptic conditions and placed in 30 ml transport medium immediately upon resection. Three types of transport medium were used for tissue: viz. Dulbecco?s phosphate-buffered saline (PBS; Gibco Life Technologies, Paisley, Scotland) for DNA, RNA later (Ambion Inc., Woodward st. Austin, Texas, USA) for RNA and optimum cutting temperature compound (Sigma, St. Louis, MO, USA) for protein. 3. Atheroma DNA & RNA isolation and testing Total DNA was isolated for checking the positivity for C. pneumoniae from atheromatous plaques as described earlier [1]. Total RNA from the atheroma samples were isolated using RNeasy fibrous tissue mini kit (Qiagen Sciences, Maryland, USA) and the concentration was determined by a RNA dye-binding assay (Pico-Green, Molecular Probes, Eugene, OR). For cDNA synthesis, RETRO script (Ambion Inc., Woodward st. Austin, Texas, USA) was used as per manufacturer instructions. For detecting positivity for C. pneumoniae, Helicobacter pylori, Cytomegalovirus and Herpes Simplex Virus in atheromatous plaques, multiplex RT-PCR was performed [as describe in reference 1]. Monoplex RT PCR amplification primers and probes were custom designed by Applied Biosystems (Foster City, CA, USA). Briefly, sequences for the 16S rRNA and HSP60 gene of the organisms of interest were aligned and inspected for regions of conserved and variable sequences. 4. Microarray experiment Further study was performed only on cHSP60 positive (negative for H. pylori, CMV & HSV-1) and cHSP60 negative (also negative for H. pylori, CMV & HSV-1) CAD patients. cHSP60 positive samples represented the test samples and cHSP60 negative samples represented the control samples. 3 samples were analysed: samples 17 and 23 were biological replicates of test samples and also performed in duplicate as technical replicates, and sample 26 was a control sample and was also performed in duplicate as a technical replicate.
