Clinical Trial Summary

Delirium and acute neurocognitive impairment are increasingly observed in adult and pediatric patients with COVID-19. Prospective clinical studies combining clinical and laboratory examinations including specific biomarkers of neuroaxonal injury were not performed for COVID-19. The value of biomarkers of neuroaxonal injury was proven in preliminary studies. These biomarkers could thus contribute to the systematic detection of neurocognitive impairment in patients with COVID-19. Due to worldwide increasing numbers of hospitalized patients with COVID-19, biomarkers of neuroaxonal injury are highly valuable to detect and monitor cognitive impairment, especially with regard to limited resources available to perform time-consuming brain imaging.

Biomarkers of neuroaxonal injury are therefore not only of great interest to detect neurocognitive impairment but also to quantify the severity of brain injury in patients with COVID-19.

Description:

This is a multicenter observational study evaluating the incidence and severity of neurocognitive impairment in adult and pediatric patients with COVID-19. All study participants will be assessed by clinical and neurological examination as well as comprehensive laboratory tests using biomarkers of neuroaxonal injury at study day 1 (day of study inclusion), day 3, day 7 and day of hospital discharge. A panel of biomarkers (among others NSE, S100B and neurofilament proteins) will be measured. Clinical assessment will be performed using validated delirium tests (among others CAM-ICU, ICDSC) and scales to assess the neurocognitive performance of study participants before and three months after study inclusion (among others Short Blessed Test).

A group of patients with a comparable severity of disease but without the detection of SARS-Cov-2 will serve as control group and will undergo the same clinical and laboratory examinations.

We hypothesize, that:

• patients with COVID-19 are more likely to develop delirium and neurocognitive impairment than patients without COVID-19

• patients with a preexisting neurocognitive deficit are more vulnerable to neurocognitive impairment in the course of COVID-19 than patients without a preexisting neurocognitive deficit

• Specific biomarkers of neuroaxonal injury correlate with the clinical severity of acute neurocognitive impairment and can predict the 3-month neurocognitive outcome of patients with COVID-19
