Investigating COVID-19 effects in children

Investigation of Prognostic Biomarkers, Host Factors and Viral Factors for COVID-19 Associated Encephalopathy/Encephalitis and Multi-systemic Inflammatory Syndrome in Children

Observational National Taiwan University Hospital · NCT05576714

This study is trying to learn more about how COVID-19 affects children, especially those with serious conditions like encephalitis or MIS-C, by looking at their symptoms and test results.

What this trial studies

This observational study aims to identify prognostic biomarkers, host genetic factors, and viral factors associated with COVID-19 in children, particularly focusing on COVID-19-associated encephalitis and multisystem inflammatory syndrome in children (MIS-C). Pediatricians will enroll hospitalized children under 18 years old who have tested positive for SARS-CoV-2 and exhibit symptoms of encephalitis or MIS-C. Clinical assessments, lab findings, and outcomes will be collected to better understand the severity and implications of these conditions. The study seeks to enhance knowledge of the immunopathogenesis and viral pathogenesis related to COVID-19 in the pediatric population.

Who should consider this trial

Good fit: Ideal candidates are hospitalized children under 18 years old with a positive SARS-CoV-2 test and clinical signs of encephalitis or MIS-C.

Not a fit: Patients who do not have COVID-19 or those over 18 years old will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prognostic tools and treatment strategies for children affected by severe COVID-19 complications.

How similar studies have performed: Other studies have indicated neurological complications in children with COVID-19, suggesting that this investigation builds on existing knowledge rather than being entirely novel.
