ABSTRACT
We established the COVID Human Genetic Effort (www.covidhge.com) to discover the human genetic and immunological bases of the vast interindividual clinical variability between humans infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We found that about 3% of patients with life-threatening coronavirus disease 2019 (COVID-19) pneumonia were ill because of inborn errors of genes controlling type I interferon (IFN)-dependent immunity (which controls influenza virus), and at least 10% of patients with life-threatening COVID-19 pneumonia had neutralizing auto-Abs against some of the 17 individual type I IFNs. These findings indicate that impaired type I IFN immunity underlies life-threatening COVID-19 pneumonia in at least 13% of patients. These discoveries pave the way for further research into unexplained severe cases, and provide a rationale for preventing and treating the disease in individuals at risk, with recombinant type I IFNs.
Nous avons créé le COVID Human Genetic Effort (www.covidhge.com) afin de découvrir les bases génétiques et immunologiques expliquant l'immense variabilité clinique interindividuelle entre les humains infectés par le nouveau coronavirus 2 du syndrome respiratoire aigu sévère (SRAS-CoV-2). Nous avons découvert qu'environ 3% des patients atteints de pneumonie sévère à coronavirus 2019 (COVID-19) menaçant leur pronostic vital étaient malades en raison de défauts génétiques dans les gènes contrôlant l'immunité dépendant de la voie de l'interféron (IFN) de type I (qui contrôle le virus de la grippe), et qu'au moins 10% de ces patients avaient des auto-anticorps neutralisants contre certains des 17 IFN de type I. Ces résultats indiquent qu'un défaut de l'immunité dépendante des IFN de type I est à l'origine de la sévérité de la pneumopathie à COVID-19 chez au moins 13% des patients. Ces découvertes ouvrent la voie à d'autres recherches sur des cas graves inexpliqués de COVID-19 et sont un argument en faveur de l'utilisation d'IFNs de type I recombinants pour la prévention et le traitement de la maladie chez les personnes à risque.
