Abstract Background Inflammation plays a role in the development of ischaemic cerebrovascular events. High sensitivity C-reactive protein (CRP) is known to predict recurrent events. Little data exists for more upstream serum markers of inflammation. Methods BIO-STROKE and BIO-TIA were multicentre prospective biomarker and imaging studies of patients with non-severe stroke, TIA and controls. Exclusion criteria were malignancy, infection, recent trauma / surgery, recurrent stroke before phlebotomy/MRI. Serum biomarkers analysed included Interleukin (IL) – 6, CRP, IL-1, IL-8, IL10, IL12p70, IFN and TNF.Plasma CRP and IL-6 were measured by mass spectrometry. Additional biomarkers were measured using ELISA. Follow up was performed at 7, 28, 90 days and 1 year. Results 680 patients (439 strokes, 241 TIAs) and 68 controls were included in the analysis. The median age was 70 for cases. Carotid stenosis was present in 23.6% of cases. Median CRP was 3.75mg/L, 2.36mg/l and 1.87mg/L in the stroke, TIA and control groups (p=<0.001). Median IL-6 was 5.86pg/ml (stroke), 4.25pg/ml (TIA), 3.06pg/ml (control) (p=<0.001). On multivariate cox regression analysis baseline IL6 and CRP were independent predictors of all cause death at 1 year with a HR of 1.005 (95% CI 1.002-1.007, p<0.001).and 1.005(95% CI 1.002-1.007, p<0.001) per unit increase. Both IL6 and CRP were associated with vascular death at 1 year. In adjusted analyses, IL6 and CRP were associated with poor functional outcome at 1 year (OR of 1.02(CI 1.01 -1.03) and 1.02(CI 1.01-1.03) per unit increase, for IL6 and CRP respectively). On adjusted analysis, when IL6 was analysed as quartiles, there was a strong association with death at 1 year with an OR 1.87 (95% CI 1.19-2.93).CRP, analysed as quartiles, demonstrated an OR for death at 1 year of 1.64 (1.10-2.46). Conclusion IL-6 and CRP may be a useful prognostic factor for the prediction of outcome and death after stroke at 1 year follow up.

Background: C-reactive protein is a biomarker among the spontaneous intracerebral haemorrhage patients.Objective: The purpose of this present study was to see the association of CRP level with the short term clinical outcome among spontaneous intracerebral haemorrhage patients.Methodology: This prospective cohort study was conducted in the Department of Neurology at Dhaka Medical College and Hospital, Dhaka, Bangladesh from July 2012 to June 2014 for a period of two (02) years. Patients presented with first ever spontaneous intracerebral haemorrhage with the age group of more than or equal to 18 years with both sexes and hospital admission within 48 hours of onset were included for this study. Admission plasma CRP was measured and study population were divided into group I (plasma CRP≥6 mg/L) and group II (plasma CRP<6 mg/L). The patients were observed daily till 1 week after admission with special attention to vital parameters and clinical outcome which were mortality, functional outcome and early neurological worsening. Finally findings were analyzed and clinical outcome were compared in patient with different level of admission plasma CRP.Result: Early neurological worsening at the end of first week was 37(38%) patients. Poor functional outcome (GOS 2-3) at the end of first week was found in 51(52%) patients. Overall mortality within that period was 16(17%) patients. Elevated CRP level was associated with higher proportion of GCS score < 9 at day seven. Early neurological worsening and poor functional outcome (GOS2-3) was also found more in these patients.Conclusion: High admission plasma CRP level may be associated with higher proportions of poor short term outcome (GOS 2-3), early neurological worsening at the end of the first week after onset and mortality within this period in the patients with spontaneous intracerebral haemorrhage.Journal of National Institute of Neurosciences Bangladesh, 2017;3(2): 89-93

Background Recent randomised trials showed benefit for anti-inflammatory therapies in coronary disease but excluded stroke. The prognostic value of blood inflammatory markers after stroke is uncertain and guidelines do not recommend their routine measurement for risk stratification. Methods We performed a systematic review and meta-analysis of studies investigating the association of C-reactive protein (CRP), interleukin-6 (IL-6) and fibrinogen and risk of recurrent stroke or major vascular events (MVEs). We searched EMBASE and Ovid Medline until 10/1/19. Random-effects meta-analysis was performed for studies reporting comparable effect measures. Results Of 2,515 reports identified, 39 met eligibility criteria (IL-6, n = 10; CRP, n = 33; fibrinogen, n = 16). An association with recurrent stroke was reported in 12/26 studies (CRP), 2/11 (fibrinogen) and 3/6 (IL-6). On random-effects meta-analysis of comparable studies, CRP was associated with an increased risk of recurrent stroke [pooled hazard ratio (HR) per 1 standard-deviation (SD) increase in loge-CRP (1.14, 95% CI 1.06–1.22, p < 0.01)] and MVEs (pooled HR 1.21, CI 1.10–1.34, p < 0.01). Fibrinogen was also associated with recurrent stroke (HR 1.26, CI 1.07–1.47, p < 0.01) and MVEs (HR 1.31, 95% CI 1.15–1.49, p < 0.01). Trends were identified for IL-6 for recurrent stroke (HR per 1-SD increase 1.17, CI 0.97–1.41, p = 0.10) and MVEs (HR 1.22, CI 0.96–1.55, p = 0.10). Conclusion Despite evidence suggesting an association between inflammatory markers and post-stroke vascular recurrence, substantial methodological heterogeneity was apparent between studies. Individual-patient pooled analysis and standardisation of methods are needed to determine the prognostic role of blood inflammatory markers and to improve patient selection for randomised trials of inflammatory therapies.

Background The Japan Statin Treatment Against Recurrent Stroke (J-STARS) is a clinical trial that administered pravastatin for secondary stroke prevention. Lipid concentrations are a well-established risk factor for cerebrovascular diseases. Elevated high-sensitivity C-reactive protein (hs-CRP) indicates a high risk of inflammatory reactions. In clinical trials, internationally approved standardization is essential for obtaining study results that are comparable with those from overseas. Therefore, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG) and hs-CRP were standardized throughout a 10-year study period. Methods J-STARS specified a single clinical laboratory for blood analyses. Four lipids were evaluated by calculating the total error: accuracy (absolute mean %bias vs. reference value) + precision (1.96 among-run coefficient of variation [CV, %]). Accuracy for hs-CRP was ensured using a calibrator traceable to the international plasma protein reference material and precision was evaluated by CV. Results Average total errors (standard deviation, %) throughout the study period were as follows: TC 1.35% (0.290%), HDL-C 2.45% (1.087%), LDL-C 2.65% (0.956%) and TG 3.70% (0.559%). Four lipids met the performance criteria of the US Centers for Disease Control and Prevention (CDC). The precision of hs-CRP was 3.28% (0.627%), which met the performance criterion established by the American Heart Association/CDC. Conclusions Based on standardization, the results of J-STARS appear to be comparable with those of similar intervention-based clinical studies on statins overseas. These study results will contribute to the establishment of preventive measures against recurrent stroke in Japanese patients. J-STARS is registered in ClinicalTrials.gov under NCT00221104.

Background and Purpose: It is still unclear whether the residual cholesterol and inflammatory risk in the acute phase is associated with prognosis of stroke. We aimed to investigate the proportion and relative contribution of residual cholesterol and inflammatory risk, determined by baseline low-density lipoprotein cholesterol (LDL-C) and high-sensitivity C-reactive protein (hsCRP) levels, to the risk of recurrent stroke and poor functional outcome at 1 year. Methods: In this prospective multicenter cohort study, 10 499 consecutive acute ischemic stroke and transient ischemic attack patients with levels of LDL-C and hsCRP were enrolled. Patients were divided into 4 groups: residual cholesterol risk only (LDL-C ≥2.6 mmol/L and hsCRP <3 mg/L), residual inflammatory risk (RIR) only (LDL-C <2.6 mmol/L and hsCRP ≥3 mg/L), both risk (LDL-C ≥2.6 mmol/L and hsCRP ≥3 mg/L), and neither risk (LDL-C <2.6 mmol/L and hsCRP <3 mg/L). The primary outcomes consisted of stroke recurrence and a modified Rankin Scale score of 2 to 6 within 1 year. Results: The relative proportions of patients with RIR only, residual cholesterol risk only, both risk, and neither were 21.3%, 23.7%, 14.4%, and 40.6%, respectively. RIR only was independently associated with recurrent stroke (adjusted hazard ratio, 1.18 [95% CI, 1.00–1.40]; P =0.05). The association was slightly attenuated after further adjusting for usage of antiplatelet agent and statin during 1-year follow-up in addition to the traditional risk factors (hazard ratio, 1.31 [95% CI, 0.99–1.76]; P =0.07). When applying the LDL-C cutoff value of 1.8 mmol/L in the sensitivity analyses, such association in large-artery atherosclerosis subtype was more significant (adjusted hazard ratio, 1.69 [95% CI, 1.06–2.67]; P =0.03). Patients with RIR only also had increased risk of poor functional outcome (adjusted odds ratio, 1.43 [95% CI, 1.24–1.64]; P <0.0001). Conclusions: In the patients with acute ischemic stroke or transient ischemic attack, RIR only could be predictive for recurrent stroke, especially for those with large-artery atherosclerosis, and poor functional outcome.

ObjectiveTo determine the relationship of high-sensitive C-reactive protein (hsCRP) and the efficacy and safety of dual antiplatelet therapy in patients with and without intracranial arterial stenosis (ICAS) in the Clopidogrel in High-Risk Patients with Acute Non-disabling Cerebrovascular Events (CHANCE) trial.MethodsA subgroup of 807 patients with both magnetic resonance angiography images and hsCRP measurement was analyzed. Cox proportional hazards models were used to assess the interaction of hsCRP levels with the effects of dual and single antiplatelet therapy.ResultsA total of 358 (44.4%) patients had ICAS and 449 (55.6%) did not. The proportion of patients with elevated hsCRP levels was higher in the ICAS group than in the non-ICAS group (40.2% vs 30.1%, p = 0.003). There was significant interaction between hsCRP and the 2 antiplatelet therapy groups in their effects on recurrent stroke after adjustment for confounding factors in the patients with ICAS (p = 0.012), but not in those without (p = 0.256). Compared with aspirin alone, clopidogrel plus aspirin significantly reduced the risk of recurrent stroke only in the patients with ICAS and nonelevated hsCRP levels (adjusted hazard ratio 0.27; 95% confidence interval 0.11 to 0.69; p = 0.006). Similar results were observed for composite vascular events. No significant difference in bleeding was found.ConclusionsPresence of both ICAS and nonelevated hsCRP levels may predict better response to dual antiplatelet therapy in reducing new stroke and composite vascular events in minor stroke or high-risk TIA patients. Further large-scale randomized and controlled clinical trials are needed to confirm this finding.
