Highlights Largest cohort of patients with COVID-19 and neurological symptoms who underwent LP. In all 30 cases, RT-PCR for SARS-CoV-2 from CSF was negative. CSF analysis findings, including WBC, were normal in most patients with COVID-19. Neurological symptoms in COVID-19 seem to be caused mainly by indirect mechanism.
Background Neurologic manifestations are increasingly reported in patients with coronavirus disease 2019 (COVID-19). Yet, data on prevalence, predictors and relevance for outcome of neurological manifestations in patients requiring intensive care are scarce. We aimed to characterize prevalence, risk factors and impact on outcome of neurologic manifestations in critically ill COVID-19 patients. Methods In the prospective, multicenter, observational registry study PANDEMIC (Pooled Analysis of Neurologic DisordErs Manifesting in Intensive care of COVID-19), we enrolled COVID-19 patients with neurologic manifestations admitted to 19 German intensive care units (ICU) between April 2020 and September 2021. We performed descriptive and explorative statistical analyses. Multivariable models were used to investigate factors associated with disorder categories and their underlying diagnoses as well as to identify predictors of outcome. Results Of the 392 patients included in the analysis, 70.7% (277/392) were male and the mean age was 65.3 (SD ± 3.1) years. During the study period, a total of 2681 patients with COVID-19 were treated at the ICUs of 15 participating centers. New neurologic disorders were identified in 350 patients, reported by these centers, suggesting a prevalence of COVID-19-associated neurologic disorders of 12.7% among COVID-19 ICU patients. Encephalopathy (46.2%; 181/392), cerebrovascular (41.0%; 161/392) and neuromuscular disorders (20.4%; 80/392) were the most frequent categories identified. Out of 35 cerebrospinal fluid analyses with reverse transcriptase PCR for SARS-COV-2, only 3 were positive. In-hospital mortality was 36.0% (140/389), and functional outcome (mRS 3 to 5) of surviving patients was poor at hospital discharge in 70.9% (161/227). Intracerebral hemorrhage (OR 6.2, 95% CI 2.5–14.9, p < 0.001) and acute ischemic stroke (OR 3.9, 95% CI 1.9–8.2, p < 0.001) were the strongest predictors of poor outcome among the included patients. Conclusions Based on this well-characterized COVID-19 ICU cohort, that comprised 12.7% of all severe ill COVID-19 patients, neurologic manifestations increase mortality and morbidity. Since no reliable evidence of direct viral affection of the nervous system by COVID-19 could be found, these neurologic manifestations may for a great part be indirect para- or postinfectious sequelae of the infection or severe critical illness. Neurologic ICU complications should be actively searched for and treated.
Background and Purpose: Coronavirus disease (COVID-19) is still considered a global pandemic. The prognosis of COVID-19 patients varies greatly. We aimed to assess the impact of preexisting, chronic neurological diseases (CNDs) and new-onset acute neurological complications (ANCs) on the disease course, its complications, and outcomes. Methods:We conducted a monocentric retrospective analysis from all hospitalized COVID-19 patients between May 1, 2020 and January 31, 2021. Employing multivariable logistic regression models, we explored the association of CNDs and ANCs separately with hospital mortality and functional outcome.Results: A total of 250 among 709 patients with COVID-19 had CNDs. We found a 2.0 times higher chance of death (95% confidence interval [CI]: 1.37-2.92) for CND patients than for non-CND patients. The chance for an unfavorable functional outcome (modified Rankin Scale > 3 at discharge) was 1.67 times higher in patients with CNDs than those without (95% CI: 1.07-2.59). Furthermore, 117 of all patients had 135 ANCs in total. We observed a 1.86 times higher chance to die (95% CI: 1.18-2.93) for patients with ANCs than without. The chance for a worse functional outcome was 3.6-fold higher in ANC patients than without (95% CI: 2.22-6.01). Patients with CNDs had 1.73 times higher odds for developing ANCs (95% CI: 0.97-3.08). Conclusion:Preexisting neurologic disorders or ANCs in COVID-19 patients were associated with higher mortality and poorer functional outcome at discharge. Furthermore, development of acute neurologic complications was more frequent in patients with preexisting neurologic disease. Early neurological evaluation appears to be an important prognostic factor in COVID-19 patients.
