Case Report: Hyperinflammatory Status in an Immunocompromised Child With a Highly Sustained Viral Load of SARS-CoV-2

Area of Science:

• Pediatric Oncology
• Infectious Diseases
• Immunology

Background:

• Limited data exist on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load dynamics in immunocompromised pediatric patients.
• Understanding these dynamics is crucial for managing Coronavirus disease 2019 (COVID-19) in vulnerable children.

Observation:

• A pediatric patient with acute myeloid leukemia presented with a unique hyperinflammatory status mimicking MIS-C during COVID-19 infection.
• The patient exhibited a sustained high SARS-CoV-2 viral load (approx. 7 log10 RNA copies/mL) for six weeks.
• Hyperinflammation developed early, coinciding with high viral load and immunocompromised status.

Findings:

• The clinical course involved late-onset fever, gastrointestinal symptoms, rash, and respiratory distress requiring oxygen.
• This case presents a unique combination of sustained high SARS-CoV-2 viral load, hyperinflammation, and an immunocompromised state in a pediatric oncology patient.
• The dynamics of SARS-CoV-2 viral load in immunosuppressed children remain largely unreported.

Implications:

• This case underscores the need for further research into COVID-19 in immunocompromised pediatric populations.
• Clinical management strategies may need to be adapted for pediatric patients with cancer and SARS-CoV-2 infection.
• Further studies are warranted to elucidate the interplay between immunosuppression, viral load, and hyperinflammation in pediatric COVID-19.
