Background and Purpose— Early presentation is critical for receiving effective reperfusion therapy for acute ischemic stroke, therefore, we undertook a national survey of awareness and responses to acute stroke symptoms in China. Methods— We undertook a cross-sectional community-based study of 187 723 adults (age ≥40 years) presenting to 69 administrative areas across China between January 2017 and May 2017 to determine the national stroke recognition rate and the correct action rate. Multivariable logistic regression models were used to identify factors associated with stroke recognition and intention-to-avail emergency medical services. Results— Estimates of stroke recognition rate and correct action rate were 81.9% (153 675/187 723) and 60.9% (114 380/187 723), respectively, but these rates varied widely by sociodemographic status, region, and stroke risk. Approximately one-third of participants who recognized a stroke failed to call emergency medical service. Low likelihood of emergency medical service use was associated with younger age (40–59 years), being male, rural location, (regions of east, south, and northwest China), high body mass index (≥24), low education (primary school or below), low personal income (<US $731 per annum), living with immediate family, having multiple children (≥2), having a friend with stroke, exposure to less avenues to learn about stroke, nonsmoking, regular exercise, unknown family history, and no history of cardiovascular disease. Intention of calling emergency medical service was strongly related to awareness of stroke (odds ratio 2.05; 95% CI, 2.00–2.10; P <0.001). Conclusions— Substantial discrepancies exist between stroke recognition and correct action and not all stroke patients know the appropriate responses. Further, national stroke educational programs with specific plans targeting different groups are needed, which do not solely focus on stroke recognition, but also on the appropriate responses at the time of a stroke.

Objective The aim of this study was to investigate the role of serum IgE levels in the clinical features and outcomes of IgG4-related disease (IgG4-RD). Methods We retrospectively enrolled 459 newly diagnosed IgG4-RD patients with serum IgE examined at baseline from 2012 to 2019 and compared the clinical features between group A (serum IgE level ≤ 60 KU/L) and group B (serum IgE level > 60 KU/L). Subsequently, 312 patients who had been followed up for ≥ 1 year were further selected to evaluate the correlation between serum IgE level and disease outcome. Results At baseline, the serum IgE level was positively correlated with the serum IgG4 level (r = 0.1779, P = 0.0001), eosinophil count (r = 0.3004, P < 0.0001), and serum IgG level (r = 0.2189, P < 0.0001) in IgG4-RD patients. Compared with group A, group B had more patients with allergic diseases (P = 0.004), more organ involvement (P = 0.003), and higher IgG4-RD responder index scores (P = 0.002). During follow-up, group A patients had a higher remission induction rate than group B patients (88.4% vs. 73.6%, P = 0.035), while group B patients had a higher relapse rate than group A patients (29.0% vs. 16.2%, P = 0.039). Multivariate analysis found that a serum IgE level > 125 KU/L at baseline was a risk factor for disease relapse (hazard ratio [HR], 1.894 [95% confidence interval (CI) 1.022–3.508]; P = 0.042). Cox regression analysis showed that elevation of the eosinophil count was a risk factor for relapse in both group A and group B patients (HR, 8.504 [95% CI 1.071–42.511]; P = 0.009; and HR, 2.078 [95% CI 1.277–3.380]; P = 0.003, respectively), and the involvement of the lacrimal gland (HR, 1.756 [95% CI 1.108–2.782]; P = 0.017), submandibular gland (HR, 1.654 [95% CI 1.037–2.639]; P = 0.035), and kidney (HR, 3.413 [95% CI 1.076–10.831]; P = 0.037) were also risk factors for relapse in group B patients. Conclusion IgG4-RD patients with high serum IgE levels at baseline were more likely to have higher disease activity, and baseline high IgE levels were associated with disease relapse.
