Plasma C-Reactive Protein and Clinical Outcomes after Acute Ischemic Stroke: A Prospective Observational Study

Abstract:: Acute Ischemic Stroke (AIS) is currently the most frequently reported neurological complication of Coronavirus disease 2019 (COVID-19). This article will elaborate on the clinical features of inpatients with COVID-19 and AIS and the pathophysiological mechanism of AIS under the background of COVID-19. Through a detailed search of relevant studies, we found that the incidence of AIS among COVID-19 patients varied from 0.9% to 4.6%, and AIS has been observed in many people without underlying diseases and cardiovascular risk factors as well as young people. The National Institute of Health Stroke Scale (NIHSS) score of COVID-19 patients with AIS was higher than historical AIS patients, and the proportion of large vessel occlusion (LVO) was about 64.2%. COVID-19 patients with AIS have commonly high levels of D-D dimer, fibrinogen, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR), suggesting systemic hyperinflammatory and hypercoagulable state. The pooled mortality of COVID-19 patients with AIS was 38% and the mortality of LVO patients is higher (45.9%). Compared with COVID-19-negative AIS patients in the same period in 2020 and 2019, COVID- 19 patients with AIS had a worse prognosis.

Background: Previous studies on inflammatory biomarkers in acute ischemic stroke (AIS) produced divergent results. We evaluated whether C-reactive protein (CRP) and white blood cell count (WBC) measured fasting 12–24 h after intravenous thrombolysis (IVT) were associated with outcome in AIS patients without concomitant infection. Methods: The study included 352 AIS patients treated with IVT. Excluded were patients with community-acquired or nosocomial infection. Outcome was measured on discharge and 90 days after stroke onset with the modified Rankin scale (mRS) and defined as poor outcome (mRS 3–6) or death (mRS = 6). Results: Final analysis included 158 patients (median age 72 years (interquartile range 63-82), 53.2% (n = 84) women). Poor outcome on discharge and at day 90 was 3.8-fold and 5.8-fold higher for patients with CRP ≥ 8.65 mg/L (fifth quintile of CRP), respectively, compared with first quintile (<1.71 mg/L). These results remained significant after adjustment for potential confounders (odds ratio (OR) on discharge = 10.68, 95% CI: 2.54–44.83, OR at day 90 after stroke = 7.21, 95% CI: 1.44–36.00). In-hospital death was 6.3-fold higher for patients with fifth quintile of CRP as compared with first quintile and remained independent from other variables (OR = 4.79, 95% CI: 1.29–17.88). Independent predictors of 90-day mortality were WBC < 6.4 × 109 /L (OR = 5.00, 95% CI: 1.49–16.78), baseline National Institute of Health Stroke Scale (NIHSS) score (OR = 1.13 per point, 95% CI: 1.01–1.25) and bleeding brain complications (OR = 5.53, 95% CI: 1.59–19.25) but not CRP ≥ 8.65 mg/L. Conclusions: Non-infective CRP levels are an independent risk factor for poor short- and long-term outcomes and in-hospital mortality in AIS patients treated with IVT. Decreased WBC but not CRP is a predictor for 90-day mortality.

The Impact

The objective of this study is to assess the impact of recanalization (spontaneous and therapeutic) on upper limb functioning and general patient functioning after stroke. This is a prospective, observational study of patients hospitalized due to acute ischemic stroke in the territory of the middle cerebral artery (n = 98). Patients completed a comprehensive rehabilitation program and were followed-up for 24 weeks. The impact of recanalization on patient functioning was evaluated using the modified Rankin Scale (mRS) and Stroke Upper Limb Capacity Scale (SULCS). General and upper limb functioning improved markedly in the first three weeks after stroke. Age, gender, and National Institutes of Health Stroke Scale (NIHSS) score at admission were associated with general and upper limb functioning at 12 weeks. Successful recanalization was associated with better functioning. Among patients who underwent therapeutic recanalization, NIHSS scores ≥16.5 indicate lower general functioning at 12 weeks (sensibility = 72.4%; specificity = 78.6%) and NIHSS scores ≥13.5 indicate no hand functioning at 12 weeks (sensibility = 83.8%; specificity = 76.5%). Recanalization, either spontaneous or therapeutic, has a positive impact on patient functioning after acute ischemic stroke. Functional recovery occurs mostly within the first 12 weeks after stroke, with greater functional gains among patients with successful recanalization. Higher NIHSS scores at admission are associated with worse functional recovery.

Functional Polymorphisms

Background: Toll-like receptor-4 (TLR4) plays a central role in the pathophysiology of acute ischemic stroke (AIS). Specific single nucleotide polymorphisms (SNPs) in TLR4 including 1063 A/G [Asp299Gly] and 1363 C/T [Thr399Ile] alter immune cell responsiveness to lipopolysaccharide (LPS) and are associated with increased rates of infection. The effect of these TLR4 SNPs on outcome following AIS is unknown. Methods: Patients were prospectively enrolled after onset of AIS. Clinical and demographic data were collected and neurological outcomes assessed at 3 months. Blood was drawn at multiple time points to quantify leukocyte subsets and assess plasma levels of C-reactive protein and a panel of cytokines. Genotyping for the TLR4 SNPs was also performed on blood samples. Uni- and multivariate analyses were performed to assess associations between TLR4 SNP haplotype and (i) each laboratory parameter noted above, (ii) infection risk and (iii) stroke outcome. Results: Of the 42 patients included; 6 (14%) were heterozygous for either one or both TLR4 SNPs. Baseline characteristics were similar in patients with or without a TLR4 SNP. In analyses adjusted for both initial stroke severity and age, the presence of a TLR4 SNP was associated with increases in blood leukocytes, plasma C-reactive protein and the cytokine interleukin-1 receptor antagonist (IL-1ra). The presence of either TLR4 SNP was also associated with a trend toward increased rates of infection (adjusted odds ratio and 95% confidence interval of 8.20 and 0.826-81.5, respectively) and a decreased likelihood of favorable outcome as defined by a modified Rankin Scale score of two or less at three months from stroke onset (0.014, 0.00-0.759). Conclusions: In AIS patients, functionally significant genetic variations in TLR4 influence both rates of stroke-associated infection and neurological outcome. These data suggest a direct connection between TLR4 function and stroke pathophysiology.
