Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), which is TNF receptor superfamily member, contributes to several diseases pathogenesis. The aim of this research was to investigate the relevance of serum TRAIL protein levels and mRNA expression in peripheral blood mononuclear cells (PBMC) of patients with stroke through 6 months follow-up. We enrolled patients with first-ever acute ischemic stroke (n = 95) and healthy controls (n = 95) in this study. Follow-up blood samples were collected from patients at day 7, 28, and 180 after the onset. The stroke severity was evaluated by National Institutes of Health Stroke Scale score. TRAIL protein levels were quantified by using ELISA kits and TRAIL mRNA expression by quantitative real-time PCR. Our study showed that stroke patients have statistically significant lower levels of serum TRAIL protein (p < 0.0001) and elevated TRAIL mRNA expression (p < 0.0001) in PBMC at the disease onset. Our follow-up study revealed that TRAIL protein levels were increased while mRNA expression levels were downregulated in later periods. Overall, our findings suggest that serum TRAIL levels and mRNA expression in PBMC could reliably serve as a predictor of stroke outcome. Additionally, our study supports that TRAIL plays a role in pathogenesis and progression of ischemic stroke.
Aims This study aimed to examine the haemogram parameters, including the neutrophil/lymphocyte ratio (NLR), which is fast, easy and practical to determine, in stroke patients who present with more physiological stress and inflammation and compare them with patients presenting other neurological diseases. Methods The demographic, laboratory and imaging features of all patients who were admitted to the neurology clinic within a three‐year period and met the study criteria were retrospectively analysed. A haemogram from peripheral venous blood samples was taken at the time of admission, and its parameters was calculated. Results A total of 3152 patients, 1604 of whom were women (50.9%), with a mean age of 66.1 ± 14 (18‐100) years who were hospitalised in the neurology clinic from 1 January 2015 to 1 January 2018, comprised the study's sample. Mean age, mean leukocyte‐neutrophil count and NLR were significantly higher in stroke patients than in those without stroke (P < .001, P < .001 and P < .001, respectively), but mean red blood cell, platelet and lymphocyte counts, and haemoglobin and haematocrit values were found to be significantly lower (P < .001, P < .001, P < .001, P < .001 and P < .001, respectively). When the haemogram parameters were compared according to stroke type, red blood cell, haemoglobin, haematocrit and NLR values in patients with haemorrhagic stroke (P = .019, P = .002, P = .002 and P = .001, respectively) and platelet and lymphocyte values in ischaemic stroke patients were found to be significantly higher (P = .002 and P < .001, respectively). Conclusion In this study, significant data obtained by comparing the haemogram parameters of those with stroke and other neurological diseases are presented. All neurological diseases, especially acute stroke and its types, should be examined in future prospective, randomised and controlled studies with all haemogram parameters, especially the NLR. However, it should be noted that haematological parameters are more useful for group studies rather than determining the diagnosis of an individual patient.
Background This study aimed to examine the hemogram parameters, including the neutrophil/lymphocyte ratio (NLR), which is fast, easy and practical to determine, in stroke patients who present with more physiological stress and inflammation and compare them with patients presenting other neurological diseases. Methods The demographic, laboratory and imaging features of all patients who were admitted to the Neurology Service within a three-year period and met the study criteria were retrospectively analyzed. A hemogram from peripheral venous blood samples was taken at the time of admission, and the NLR was calculated. Results A total of 3,152 patients, 1,604 of whom were women (50.9%), with a mean age of 66.1 ± 14 (18-100) years who were hospitalized in the neurology clinic between January 1, 2015 and January 1, 2018, comprised the study’s sample. Mean age, mean leukocyte-neutrophil count and NLR were significantly higher in stroke patients than in those without stroke (p <0.001, p <0.001 and p <0.001, respectively), but mean red blood cell, platelet and lymphocyte counts, and hemoglobin and hematocrit values were found to be significantly lower (p <0.001, p <0.001, p <0.001, p <0.001 and p<0.001 respectively). When the hemogram parameters were compared according to stroke type, red blood cell, hemoglobin, hematocrit and NLR values in patients with hemorrhagic stroke (p = 0.019, p = 0.002, p = 0.002 and p = 0.001, respectively) and platelet and lymphocyte values in ischemic stroke patients were found to be significantly higher (p = 0.002 and p <0.001, respectively). Conclusion In this study, significant data obtained by comparing the hemogram parameters of those with stroke and other neurological diseases are presented. All neurological diseases, especially acute stroke and its types, should be examined in future prospective, randomized and controlled studies with all hemogram parameters, especially the NLR (low cost)
