Background: Worse socioeconomic situation is associated with worse outcomes in stroke cases. Whether it also influences outcomes in patients treated with intravenous thrombolysis remains unknown. The aim of this study was to test the hypothesis that outcomes are less favorable in patients treated with intravenous thrombolysis in Belgrade, Serbia, than in Lille, France. Methods: We compared outcomes at day 7 and month 3, between 123 consecutive stroke patients treated with intravenous thrombolysis in Belgrade and 273 in Lille. Results: At month 3, there was no significant difference between Belgrade and Lille in patients' excellent outcomes [modified Rankin Scale 0-1; 49.6 vs. 45.4%, odds ratio (OR): 1.21, 95% confidence interval (CI): 0.79-1.86] or in death (11.4 vs. 16.1%, OR 0.67, 95% CI: 0.35-1.27). However, compared with a subgroup of age-matched patients from Lille, Belgrade patients tended to have worse outcomes. Patients from Belgrade were 16 years younger (p < 0.0001), more likely to be men (OR 2.40, 95% CI: 1.52-3.78), and more likely to be smokers (OR 2.24, 95% CI: 1.43-3.51). Also, a trend for a slightly higher rate of symptomatic hemorrhagic transformation was registered in this group (7.3 vs. 3.3%, OR 2.32, 95% CI: 0.90-5.99). In Belgrade, patients arrived 27 min earlier to the hospital (p < 0.0001), but their door-to-needle time was 37 min longer (p < 0.0001). Compared with a subgroup of age-matched patients from Lille, they tended to have worse outcomes. Conclusion: Intravenous thrombolysis-treated stroke patients in Belgrade have similar outcomes and rates of complications as those from Lille. Copyright © 2011 S. Karger AG, Basel.

Background/Objectives: The aim of our study was to investigate B cell and T cell responses in people with multiple sclerosis (PwMS) treated with ocrelizumab, a humanized anti-CD20 antibody, who were vaccinated with second and/or booster doses of various vaccine brands against COVID-19. Additionally, we detected the outcomes related to COVID-19 in PwMS after vaccination, based on follow-up for at least 12 months. Methods: We enrolled 91 PwMS on ocrelizumab and 42 healthy controls (HCs) in a prospective, single-center study, conducted at the Clinic of Neurology, UCCS, between January 2022 and October 2024. The serological responses were measured using the spike receptor-binding domain (RBD) Architect SARS-CoV-2 IgG Quant kit (Abbot), and cellular responses were measured by quantifying IFN-γ secretion in blood incubated with SARS-CoV-2 antigens. Results: A total of 58.2% (53/91) of PwMS on ocrelizumab and 100% of the HCs (42/42) were seropositive after a second or booster vaccination (p < 0.001), irrespective of the vaccine brand received. Anti-spike antibody levels were significantly lower in PwMS on ocrelizumab compared to the HCs (p < 0.001), again irrespective of the vaccine type. Interferon-γ responses were detected in 95.6% of the PwMS receiving ocrelizumab therapy and 97.6% of HCs after vaccination (p = 0.570). In our cohort, PCR-confirmed SARS-CoV-2 infections after vaccination occurred in a similar proportion of the PwMS (45/91, 49.5%) and HCs (15/32, 46.9%) (p = 0.139). Most of the PwMS (36/45, 79.2%) and HCs (13/15, 87.8%) had COVID-19 of mild severity. Conclusions: PwMS treated with ocrelizumab developed diminished humoral and robust cellular responses following two and three SARS-CoV-2 vaccinations. The obtained immunity after SARS-CoV-2 vaccination may translate into lower incidence and severity of COVID-19. © 2025 by the authors.
