Journal of Neuroinflammation volume 18Article number: 3 Cite this article. Metrics details. Inflammatory response plays an important role in many processes related to acute ischemic stroke AIS. The purpose of this study is to evaluate the association of circulating calprotectin with other inflammatory biomarkers and AIS prognosis, as well as the calprotectin content in stroke thrombi. Among the patients treated at a comprehensive stroke center between andpatients with confirmed acute ischemic injury were prospectively evaluated.

Patients with systemic inflammation or infection at onset were excluded. Higher calprotectin levels were associated with 3-month mortality, HT, and lower 3-month FI. Addition of calprotectin to clinical variables led to significant improvement in the discrimination capacity of the model [0. A multimarker approach demonstrated that patients with increased calprotectin, CRP, and NLR had the poorest outcome with a mortality rate of SA9 protein, as part of the heterodimer calprotectin, was present in all thrombi retrieved from AIS patients.

Mean SA9 content was 3. Moreover, it positively correlated with platelets Pearson r 0. Plasma calprotectin is an independent predictor of 3-month mortality and provides complementary prognostic information to identify patients with poor outcome after AIS. The presence of SA9 in stroke thrombi suggests a possible inflammatory mechanism in clot formation, and further studies are needed to determine its influence in resistance to reperfusion.

Stroke is the most frequent cause of permanent disability in adults and one of the most important causes of death [ 1 ]. Over the next years, global stroke burden is expected to increase steadily, mainly because of population aging [ 2 ]. Even after years of research, pathophysiology of brain ischemia and post-ischemic changes in the brain are not yet fully understood. Inflammation is increasingly recognized as a key element in the pathological progression of ischemic stroke.

Brain ischemia causes an immediate local immuno-inflammatory reaction with strong activation of microglia, astrocytes, and endothelial cells and release of cytokines both from activated cells and endothelium [ 3 ]. This non-specific response after brain tissue damage results in blood-brain barrier permeability and infiltration of inflammatory cells into the ischemic area [ 4 ] which have the potential to further what is blood give the composition of plasma tissue injury.

Likely, multiple inflammatory molecules have been reported as predictive markers of stroke severity and outcome and proposed as potential therapeutic targets to be modulated as a neuroprotective strategy in acute ischemic stroke AIS [ 5 ]. Neutrophil-to-lymphocyte ratio NLReasily calculated by white blood cell count on admission, has been reported as a prognostic biomarker in stroke.

High admission NLR values predict 3-month clinical outcome in thrombectomized patients [ 6 ] and are associated with symptomatic hemorrhagic transformation HT after AIS [ 7 ]. C-reactive protein CRPa sensitive what is a linear equation with two variables of inflammation rapidly produced by the liver after tissue injury or infection [ 8 ], is one of the most widely used markers in clinical practice.

In AIS patients, CRP levels have been reported to be significantly higher than controls in all ischemic stroke subtypes [ 9 ]. Calprotectin is what is the structure of a pop song heterodimer formed by two cytosolic proteins, SA8 and SA9, expressed by white blood cells, especially monocytes and neutrophils.

Studies focusing on coronary events have shown that plasma calprotectin was related to first and future coronary events, independently of traditional cardiovascular risk factors and C-reactive protein [ 11 ]. Recently, circulating calprotectin was associated with increased peripheral artery disease risk prediction, further improved when combined with high sensitivity CRP [ 12 ]. Moreover, plasma calprotectin has been proposed as a diagnostic marker of AIS [ 13 ], and inhibition of SA9 has been reported to suppress thrombus formation in experimental models of stroke [ 1415 ].

Nevertheless, calprotectin prognostic role and its association with other inflammatory biomarkers, such as CRP and NLR, have not yet been studied in stroke patients. The reading books meaning in kannada of this study is to evaluate circulating calprotectin levels as a prognosis biomarker in AIS and to analyze how it relates to other well-known inflammatory biomarkers.

Furthermore, we have studied the composition of ischemic stroke thrombi and characterized SA9 content, to assess its association with thrombus components and clinical parameters. Patients with transient ischemic attack and stroke mimics were excluded and only those with established acute ischemic injury confirmed by neuroimaging mainly diffusion-weighted MRI and some of them delayed cranial CT were included in this study. Patients how to tell if someone on tinder is active systemic inflammation or infection at onset including active cancer, post-operative patients, and active systemic infections were excluded to avoid confusion with previous inflammatory condition Fig.

MRI scans were obtained within 1 week of stroke onset using a 1. HT after AIS was identified on this follow-up neuroimaging and characterized by a stroke specialized neurologist. Venous blood samples were drawn from all patients in the emergency department before the initiation of any treatment as standard-of-care, and neutrophils, lymphocytes Alinity hq, Abbott, USAand serum glucose Architect iSR, Abbott, USA were measured by standard laboratory techniques.

The inter- and intra-assay variability averages were 7. Data are presented as the percentage of positive stained area in the total tissue area. The what is blood give the composition of plasma clinical outcome was 3-month all-cause mortality. Continuous variables with normal distributions were presented as mean with standard deviation SDwhile non-normally distributed variables were presented as median with interquartile range IQR. Normality of distributions was assessed graphically and with the Shapiro-Wilk test.

Logarithmic transformation was applied for continuous variables with skewed distributions. Continuous variables were compared between groups using the unpaired t test or the Wilcoxon rank-sum test depending on their distribution. Pairwise Spearman correlations were performed between continuous variables to evaluate correlation. Stroke subtype classification was assessed by TOAST criteria, and dichotomized etiological groups were created.

Association of baseline characteristics with outcomes was performed first with what is blood give the composition of plasma logistic regression models. In addition, variables that have been identified as what is blood give the composition of plasma covariates for poor outcome after ischemic stroke in previous studies were also included.

Selected multivariate binary logistic regression models were performed to evaluate associations between calprotectin with clinical outcomes after adjustment for potential confounders. Interactions were evaluated with the likelihood-ratio test, and stratified models were generated if the rendered p values were below 0. The Homer-Lemeshow test was used to assess the calibration what is blood give the composition of plasma the models. ROC analysis was used to compare the complete model for each outcome with and without calprotectin.

Besides, a cut-off point for each of the inflammatory markers tested NLR, CRP, and calprotectin was rendered by ROC analysis, and mortality predictions were performed according to the presence of none, 1, 2, or 3 increased markers as defined by these cut-offs. A total of patients with AIS confirmed by neuroimaging were finally included for the analysis. The mean age of our population was Among this elderly population, around HT incidence was Baseline characteristics why does my firestick keep saying no internet connection the study patients are presented in Table 1.

Median plasma calprotectin level was 1. As shown in Fig. Furthermore, lower plasma calprotectin levels after AIS were observed in patients with 3-month FI [1. Box-plots of plasma calprotectin levels by outcomes. Calculated by Wilcoxon rank-sum test. Plasma calprotectin levels correlated with neutrophil Pearson r 0.

When analyzing clinical factors, a positive correlation with age was registered Pearson r 0. Besides, higher calprotectin levels [1. Patients with confirmed cardioembolic stroke—according to TOAST criteria—showed higher calprotectin levels than patients with non-cardioembolic stroke [1. In addition, intravenous treatment with tPA was associated with a higher 3-month mortality and a higher incidence of HT after stroke.

Elevated inflammatory markers neutrophil count, NLR, CRP, and calprotectin were associated with a higher risk of mortality. No significant interactions were observed, and no stratified models were generated. When calprotectin was added to the model, both the AUC [0. Prognostic value of stroke severity and inflammatory biomarkers to predict 3-month mortality.

ROC analysis for calprotectin rendered a cut-off value of 2. This addition of the dichotomized calprotectin by cut-off also improves discrimination of the best-fit model IDI 0. Further, we stratified our study population according to the presence of none, 1, 2, or 3 of these inflammatory markers above the cut-off values Fig. Also, In the multivariate analysis, none inflammatory marker was associated with 3-month FI after adjusting for potential confounders Table 3. Furthermore, HT was more frequent in females.

Detailed results are presented in Additional file 2 : Supplementary Table 3. SA9 protein was present in all what is blood give the composition of plasma analyzed and quantification of thrombus constituents revealed that stroke thrombi contained on average The distribution pattern of SA9 through the thrombus seemed to be related with leukocyte distribution and was primarily found at the interface between red blood cell-rich and platelet-rich areas.

Besides the described distribution, SA9 was also present within platelet islets Fig. Histological staining and quantification of stroke thrombi. MSB staining shows a red blood-rich area orange-yellow, arrowhead near to a collagen area light blue, arrow. A fibrin area at the periphery appears in red asterisk. Platelet-rich regions CD42b staining in brown are related with collagen areas. Calculated by Student t test over log-transformed SA9.

Interestingly, a positive correlation was observed between SA9 and platelets Pearson r 0. When evaluating the amount of SA9 in thrombi and its association with calprotectin circulating levels, we did not see a correlation. Furthermore, no correlation between thrombus SA9 content and age, sex, functional outcome, and stroke severity was observed not shown. Finally, we observed a tendency to higher thrombi SA9 amount in cardioembolic thrombi and in those who had died Fig.

The small sample size of atherothrombotic thrombi and the low number of deaths did not allow us to reach statistical significance Additional file 2 : Supplementary Table 4. Our study shows that plasma calprotectin is a strong independent inflammatory predictor of 3-month mortality in AIS, and that improves the risk prediction of all-cause death associated to well-established factors such as stroke severity, high blood glucose, or baseline mRS.

Out of inflammatory markers evaluated, plasma calprotectin showed the highest discrimination capacity for 3-month mortality. Furthermore, SA9 as part of calprotectin heterodimer was present in all thrombus obtained by mechanical thrombectomy why have i suddenly got love handles stroke patients and seems to be higher in thrombi from patients who died and in those of what is blood give the composition of plasma etiology.

Calprotectin is produced by neutrophils and infiltrating macrophages in the ischemic brain [ 22 ]. Recently, in an experimental model of transient focal ischemia, inhibition of SA9 reduced infarct volume and brain swelling [ 22 ] and a therapeutic vaccine against MRP14 SA9 resulted in thrombosis inhibition in a murine model of ischemic stroke [ 11 ]. In addition, calprotectin overexpression has been localized in ischemic hemisphere CD11b-positive cells [ 14 ], and brain proteomic analysis has shown that calprotectin was what is blood give the composition of plasma in experimental models of brain ischemia [ 22 ].

In plasma, it is a relatively stable and easily measurable protein and has been proposed as a potential biomarker of inflammatory processes.
