ABSTRACT
Background: Nearly 55 percent of patients are said to be affected by the neurological effects of COVID-19. COVID-19 was shown to be related with stroke in 0.9 to 5% of people. It's critical to assess the impact of COVID-19 on the outcomes of acute ischemic stroke. The goal of this study was to look at the outcomes and characteristics of patients who had an acute ischemic stroke due to covid-19 infection. Results: The participants in this study were 399 people who had had a stroke. COVID-19 positivity was confirmed in 77 cases, while COVID-19 negativity was confirmed in 322. In the COVID-19 and control groups, the average age of the patients was 65.4 ± 10.2 and 65.3 ± 11.8, respectively. The Covid-19 and control groups had a mean stroke onset of 5.2 ± 2.1 and 5.7 ± 3.8 h, respectively (P = 0.12). There was a high in-hospital mortality rate among patients with COVID-19 with a rate of 11.7% compared to 4.04% among the control group (P = 0.02). At discharge, the number of patients with mRS > 2 was higher (P = 0.001) among the COVID-19. There was a correlation between the mean levels of D-Dimer (r = 0.668, P < 0.001), the severity of COVID-19 (r = 0.802, P < 0.001), and mRS > 2. Conclusion: Despite receiving equal acute care as non-COVID-19 patients, COVID-19 patients had more severe strokes and had worse outcomes. This includes a high chance of death while in the hospital as well as a significant level of disability. Neurologists should use timely and effective therapies, particularly for patients who are at a higher risk of having a stroke. This includes elderly patients, patients with severe COVID-19, patients with high levels of D-Dimer, and those with high NIHSS.
ABSTRACT
Background COVID-19 (SARS-CoV-2/2019-nCoV) is now a major public health threat to the world. Olfactory dysfunctions (ODs) are considered potential indicating symptoms and early case identification triaging for coronavirus disease 2019 (COVID-19). The most common reported comorbidities are diabetes mellitus, chronic lung disease, and cardiovascular disease. The objective of this study was to evaluate prevalence of different types of smell disorders in patients with laboratory-confirmed COVID-19 infection and impact of involved systemic diseases. Methodology A cross-sectional retrospective study has been done for patients with laboratory-confirmed COVID-19 infection (mild-to-moderate). The data collected from patient’s files and developed online electronic questionnaire (WhatsApp) based on the patients most common and recurrent reported data including: a) symptoms of olfactory dysfunction and associated covid19 symptoms fever and headache, cough, sore throat, pneumonia, nausea, vomiting and diarrhea, arthralgia and myalgia and taste dysfunction. b) Associated systemic diseases including: diabetes, hypertension, asthma, chronic renal disease, chorionic liver disease and hypothyroidism. Results Of 308 patients confirmed with Covid-19 infection, (72.4%) developed OD distributed as follows;complete anosmia (57.8%), troposmia (8.4%), hyposmia (2.9%), partial anosmia (2.6%) and euosmia (0.6%). Significantly increased prevalence of diabetes, hypertension asthma in the group with olfactory dysfunction (p < 0.001), chronic liver disease (p = 0.005), and hypothyroidism (p = 0.03). Conclusion The development of ODs after Covid-19 infection was associated with mild disease form and lower hospitalization. In addition, it showed significant relationship with preexisting systemic diseases. Anosmia is the common modality of ODs.
