    Background: Increased interest in the relationship between affective disorder and long-term health consequences has generated recent examinations of depression and stroke. Observations suggest that depressive disorder is associated with abnormal physiological and immunological responses and a resultant increase in inflammatory markers. Given the high prevalence of stroke and associated costs for the community, it is important to understand the mechanisms that may impact on the outcome to achieve the best possible prognosis. Aims: The view that inflammatory factors contribute to depression is predicated on findings that circulating cytokines and other inflammatory factors are increased in depressed patients. Therefore, it has been hypothesized that inflammation could be one of the mechanisms by which depression increases risk for ischemic stroke. Our aim was to determine whether there is any relationship between major depression and tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), IL-18, brain-derived neurotrophic factor (BDNF), and neuron-specific enolase (NSE) in patients with acute ischemic stroke (AIS). Study Design: This was as a cross-sectional design. Materials and Methods: This study has a cross-sectional design, and it was conducted in Necmettin Erbakan University, the Meram Faculty of Medicine in Konya, Turkey, between 2014 and 2015. Fifty-three AIS patients admitted to the hospital within the first 24 h after stroke onset were recruited. Major depression was ascertained by means of the structured clinical interview for the diagnostic and statistical manual of mental disorders, Fourth Edition/Clinical Version. The enzyme-linked immunosorbent assay was used to measure the serum levels of TNF-alpha, IL-1 beta, IL-18, BDNF, and NSE at admission. Results: A total of 53 patients with a mean age of 65.9 years were recruited. Of these patients, 17 (32.1%) had major depression. Depressive and nondepressive patients had similar demographical and clinical features. There was no significant statistical difference between depressive and nondepressive patients with AIS with respect to levels of TNF-alpha, IL-1 beta, IL-18, BDNF, and NSE. Conclusion: This study suggests that in patients who have experienced AIS, there is no significant relationship between major depression and basal proinflammatory cytokines (TNF-alpha, IL-1 beta, IL-18), BDNF, and NSE.

    Delirium in patients with acute ischemic stroke admitted to the non-intensive stroke unit: Incidence and association between clinical features and inflammatory markers
    (Termedia Publishing House Ltd, 2017) Kozak, Hasan Huseyin; Uguz, Faruk; Kilinc, Ibrahim; Uca, Ali Ulvi; Tokgoz, Osman Serhat; Akpinar, Zehra; Ozer, Nejla
    Background: Stroke patients with development of delirium have unfavorable outcomes, higher mortality, longer hospitalizations, and a greater degree of dependence after discharge. Studies suggest that delirium is associated with abnormal immunological responses and a resultant increase in inflammatory markers. Objective: Our aim was to determine whether there is an entity relationship between delirium, inflammation and acute ischemic stroke (AIS). Methods: Sixty AIS patients admitted to the hospital were consecutively recruited. Delirium was diagnosed with the clinical assessment according to the Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) criteria. Enzyme-linked immunosorbent assay (ELISA) was used to measure serum levels of Interleukin-1 beta (IL-1 beta), Interleukin 18 (IL-18), Tumor Necrosis Factor-alpha (TNF-alpha), Brain-Derived Neurotrophic Factor (BDNF), and Neuron Specific Enolase (NSE) at admission. Results: Eleven (18.3%) of 60 patients were diagnosed with delirium, and the majority (n = 8, 72.7%) was the hypoactive type. Delirious and non-delirious patients had similar demographic and clinical features. Delirious patients had significantly higher lengths of hospital stay, National Institutes of Health Stroke Scale (NIHSS) at admission and discharge compared to non-delirious patients. In addition, there was no significant statistical difference between delirious and non-delirious patients with AIS in respect of levels of TNF-alpha, IL-1 beta, IL-18, BDNF and NSE. This study suggests that delirium is not scarce in patients with AIS admitted to the non-intensive stroke unit, and that delirium developing after AIS seems not to be associated with serum TNF-alpha, IL-1 beta, IL-18, BDNF and NSE but is associated with length of hospital stay and stroke severity.

    Diagnostic and Prognostic Significance of Neutrophil Gelatinase-Associated Lipocalin and Pentraxin-3 in Acute Coronary Syndrome
    (Galenos Publ House, 2017) Ozer, Muhammet Rasit; Ergin, Mehmet; Kilinc, Ibrahim; Dundar, Zerrin Defne; Ozer, Nejla; Onal, Mehmet Akif; Girisgin, Abdullah Sadik
    Aim: The aim was to evaluate the levels of serum pentraxin-3 (PTX-3) and neutrophil gelatinase-associated lipocalin (NGAL) and the efficiency of making a diagnosis and to estimate the prognosis in patients with chest pain. Materials and Methods: The study was conducted in the Necmettin Erbakan University Meram Medicine School Emergency Department. Patients who had chest pain and met the inclusion criteria were accepted. They were divided into the following groups: acute coronary syndrome (ACS), a diagnosis other than ACS (non-ACS), and control. The patients in theACS and non-ACS groups were divided into five sub-group - groups: ST Elevated Myocardial Infarction (STEMI) Non-ST Elevated Myocardial Infarction (NSTEMI), Unstable Angina Pectoris (USAP), stable angina, and pulmonary embolus. For all patients, serum PTX-3, serum NGAL, troponin I, and creatine kinase-MB fraction (CK-MB) levels were measured. Results: There were 199 patients in the ACS and non-ACS groups and 30 patientsin the control group. There was no significant difference among the study groups in terms of age and PTX-3 and NGAL levels. When comparing survival and non-survival in terms of in-hospital death, CK-MB and troponin I levels were significantly higher in the ACS and non-ACS groups than in the control groups, whereas there was no significant difference in terms of PTX-3 and NGAL levels. Conclusion: The results of our study demonstrated that PTX-3 and NGAL are not effective biomarkers in the differential diagnosis and the determination of in-hospital mortality in ACS. However, the limitations of the study should be considered. The results confirmed that CK-MB and Troponin I can be safely used in the differential diagnosis and the prediction of mortality.
