Objective:

To investigate determinants of severity in a patient with severe West Nile Virus and SARS-CoV-2 infections, focusing on the role of anti-interferon autoantibodies and genetic predispositions, which may inform treatment strategies.

Key Findings:
  • Patient had severe infections from both WNV and SARS-CoV-2, highlighting the need for vigilant monitoring.
  • Thymoma was present during both infections, suggesting a potential link to the severity of the patient's condition.
  • Genetic variants increased susceptibility to severe COVID-19 and WNV, indicating the importance of genetic screening.
  • Neutralizing autoantibodies against type I IFNs were present, which may have impaired the antiviral response.
Interpretation:

The combination of thymoma, genetic predispositions, and autoantibody production significantly contributed to the patient's severe infections, underscoring the need for careful evaluation and tailored treatment in similar cases.

Limitations:
  • Study based on a single patient case, limiting generalizability and necessitating further research.
  • Retrospective identification of thymoma may affect conclusions, as earlier detection could alter management strategies.
Conclusion:

This case underscores the importance of assessing underlying conditions and genetic factors in patients with severe viral infections, particularly regarding the role of anti-IFN autoantibodies, to improve patient outcomes.
