AIM To determine peripheral blood lymphocyte subsets--T cells, helper T cells, cytotoxic T cells, B cells, and natural killer cells, natural killer cell cytotoxicity, serum cortisol concentration, and lymphocyte glucocorticoid receptor expression in Croatian combat veterans diagnosed with chronic posttraumatic stress disorder (PTSD); and to examine the(More)
OBJECTIVES The objectives of this study were to assess the influence of trauma caused by forced expulsion from home in a war-ravaged region on the psychological, hormonal, and immune responses in displaced persons and to analyze the relationships between psychometric, hormonal, and immunologic variables. METHODS Participants were 20 displaced and 14(More)
BACKGROUND There is increasing evidence that chronic stress accelerates telomere erosion in leukocytes/peripheral blood mononuclear cells (PBMCs). However, functional changes associated with telomere shortening are poorly understood. We hypothesized that war veterans with PTSD would have shorter telomeres in PBMCs and that these cells might exhibit changes(More)
OBJECTIVE It is assumed that stress-related changes in the endocrine and immune systems are key mediators involved in the development of diseases associated with posttraumatic stress disorder (PTSD). Evidence suggests that those changes might be related to the duration of PTSD. The aim of our study was to investigate the differences in selected endocrine-(More)
BACKGROUND Toll-like receptors (TLRs) are part of the innate immune system, able to recognize pathogen-associated molecular patterns and activate immune system upon pathogen challenge. Respiratory syncytial virus (RSV) is a RNA virus particularly detrimental in infancy. It could cause severe lower respiratory tract disease and recurrent infections related(More)
A number of peripheral blood analytes have been proposed as potential biomarkers of post-traumatic stress disorder (PTSD). Few studies have investigated whether observed changes in biomarkers persist over time. The aim of this study was to investigate the association of combat-related chronic PTSD with a wide array of putative PTSD biomarkers and to(More)
An association between traumatic stress and cardiovascular disease (CVD) is supported by various epidemiological studies. Platelet activation and binding of activated platelets to leukocytes contributes to the pathophysiology of CVD. Evidence of hyperactive sympathetic nervous system, altered expression of platelet α(2)-adrenoreceptors (α(2)AR), and altered(More)
OBJECTIVE To examine the effect of posttraumatic stress disorder (PTSD) on the measures of immune function and the hypothalamic-pituitary-adrenal axis components, and to determine whether additional life stressors affect measured variables. METHODS We simultaneously examined the natural killer cell cytotoxicity (NKCC), perforin and glucocorticoid receptor(More)
Psychological and hormonal responses to various degrees of war-related traumatic experience were analysed in 91 subjects. Their psychological responses (psychosomatic, personality traits, etc.) were evaluated by the COR-NEX2 test. Based on test results, the subjects were classified into three groups: G1 = normal, G2 = moderate, and G3 = severe response. The(More)
BACKGROUND Regulatory T cells (Tregs) play a key role in immune homeostasis in vivo. Tregs have a critical role in preventing the development of autoimmune diseases and defects in Treg function are implicated in various autoimmune disorders. Individuals with posttraumatic stress disorder (PTSD) have higher prevalence of autoimmune disorders than the general(More)
