Prognostic indicators and outcomes of hospitalised COVID-19 patients with neurological disease: An individual patient data meta-analysis.

BACKGROUND: Neurological COVID-19 disease has been reported widely, but published studies often lack information on neurological outcomes and prognostic risk factors. We aimed to describe the spectrum of neurological disease in hospitalised COVID-19 patients; characterise clinical outcomes; and investigate factors associated with a poor outcome. METHODS: We conducted an individual patient data (IPD) meta-analysis of hospitalised patients with neurological COVID-19 disease, using standard case definitions. We invited authors of studies from the first pandemic wave, plus clinicians in the Global COVID-Neuro Network with unpublished data, to contribute. We analysed features associated with poor outcome (moderate to severe disability or death, 3 to 6 on the modified Rankin Scale) using multivariable models. RESULTS: We included 83 studies (31 unpublished) providing IPD for 1979 patients with COVID-19 and acute new-onset neurological disease. Encephalopathy (978 [49%] patients) and cerebrovascular events (506 [26%]) were the most common diagnoses. Respiratory and systemic symptoms preceded neurological features in 93% of patients; one third developed neurological disease after hospital admission. A poor outcome was more common in patients with cerebrovascular events (76% [95% CI 67-82]), than encephalopathy (54% [42-65]). Intensive care use was high (38% [35-41]) overall, and also greater in the cerebrovascular patients. In the cerebrovascular, but not encephalopathic patients, risk factors for poor outcome included breathlessness on admission and elevated D-dimer. Overall, 30-day mortality was 30% [27-32]. The hazard of death was comparatively lower for patients in the WHO European region. INTERPRETATION: Neurological COVID-19 disease poses a considerable burden in terms of disease outcomes and use of hospital resources from prolonged intensive care and inpatient admission; preliminary data suggest these may differ according to WHO regions and country income levels. The different risk factors for encephalopathy and stroke suggest different disease mechanisms which may be amenable to intervention, especially in those who develop neurological symptoms after hospital admission.

The Common Neurological Presentations and Clinical Outcomes of Coronavirus Disease 2019 in Saudi Arabia.

Background: Neurological manifestations have increasingly become recognized in COVID-19. People from different ethnic backgrounds are experiencing different outcomes related to SARS-CoV-2 infection. Several cohort studies reported the common neurological manifestations and complications associated with COVID-19 disease around the world however, the prevalence of neurological complications associated with SARS-CoV-2 infection in the Arab countries and Saudi Arabia is still unknown. Objective: To study the prevalence, risk factors, and characteristics of the neurological complications associated with COVID-19 and their relationship with clinical outcomes. Methods: We conducted a prospective, single-center, observational, cohort study of consecutive hospitalized adults COVID-19 patients with and without neurological manifestation admitted between March 2020 until the end of December 2020. Data was collected prospectively using electronic medical records; Cases and controls were observed until they either get discharged from the hospital or died. The primary outcomes were death, survival, and survival with sequalae. Results: Among 497 patients with COVID-19, 118 patients (23.7%) had neurological complications, 94 patients (18.9%) had encephalopathy, and 16 patients (3.2%) had cerebrovascular accidents (CVA). Patients with COVID-19-related neurological complications were older and more likely to have a pre-existing neurological disease. The most common neurological syndrome associated with COVID-19 were encephalopathy (18.9%) and headache (13.7%). Pre-existing neurological disease and an elevated neutrophil count were the strongest predictors of developing any neurological complications. Death form COVID-19 was associated with age (OR 1.06, 95% CI 1.02-1.10, P = 0.001), invasive ventilation (OR 37.12, 95% CI 13.36-103.14), COVID-19-related-neurological complications (OR 3.24, 95% CI 1.28-8.21, P = 0.01), and elevated CRP level (OR 1.01, 95% CI 1.00-1.01, P = 0.01). Conclusions: COVID-19 is associated with a wide range of neurological manifestations in people living in Saudi Arabia, with older individuals and those with underlying neurological disorders being most at risk. The presence of neurological complications was associated with increased mortality and poor outcomes.

Is COVID-19 associated with self-reported audio-vestibular symptoms?

OBJECTIVE: To determine if a positive test for COVID-19 is associated with self-reported audio-vestibular symptoms. DESIGN: Self-reported changes in hearing, tinnitus, hyperacusis, and dizziness/rotatory vertigo were assessed in hospitalised and non-hospitalised COVID-19 patients during and after the acute phase of the disease and compared to non-COVID controls. STUDY SAMPLE: There were 150 severe cases of COVID-19 requiring hospital admission and 150 mild cases that were managed at home. Controls were 267 adults, 32 of whom had been hospitalised for a non-COVID-19 condition, and a further 85 who worked in hospital settings. RESULTS: Deterioration in hearing and/or tinnitus was reported in 8% of the COVID-19 cases (tinnitus had resolved in 2% after the acute phase), with no significant difference between severe and mild cases. Deterioration in hearing or tinnitus was not significantly different from controls. However, rotatory vertigo was reported by 5% in the COVID-19 groups and 1.1% in the controls, and this difference was statistically significant. CONCLUSIONS: There is no evidence that COVID-19 results in deterioration in hearing or tinnitus during the acute phase or after recovery in mild or severe cases. However, rotatory vertigo, which could be vestibular in origin, may be a clinical manifestation of COVID-19.

A Unique Presentation of Delirium in a Patient with Otherwise Asymptomatic COVID-19.

OBJECTIVE: Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), manifests with a wide spectrum of presentations. Most reports of COVID-19 highlight fever and upper respiratory symptoms as the dominant initial presentations, consistent with the World Health Organization guidelines regarding suspected SARS-CoV-2 infection. However, atypical presentations of this disease have been evolving since the initial outbreak of the pandemic in December 2019. We report a case of an older male patient who presented at our hospital with an unusual manifestation of COVID-19. DESIGN: Brief report. SETTING: A university hospital in Saudi Arabia. PARTICIPANT: A 73-year-old man who presented with confusion in the absence of any respiratory symptoms or fever. INTERVENTION: The patient was initially admitted with delirium and underwent a further work-up. MEASUREMENTS: Given his recent history of domestic travel and the declaration of a global COVID-19 pandemic status, the patient was administered a swab test for SARS-CoV-2. RESULTS: The patient's positive test led to a diagnosis of COVID-19. Although he began to experience a spiking fever and mild upper respiratory symptoms, he recovered rapidly with no residual sequela. CONCLUSION: The recognition of atypical presentations of COVID-19 infection, such as delirium, is critical to the timely diagnosis, provision of appropriate care, and avoidance of outbreaks within healthcare facilities during this pandemic.
