Le poumon vieilli face au COVID-19
Résumé
Le coronavirus 2019 (Covid-19) a jusqu’à présent tué de nombreuses personnes. La majorité des décès est survenue chez des personnes de plus de 65 ans. Une des constatations les plus fréquentes est que la gravité et l’évolution du Covid-19 dépendent en grande partie de l’âge du patient. La combinaison de trois facteurs pourrait expliquer ce constat : le premier est lié au vieillissement pulmonaire, le second est lié aux comorbidités associées chez le sujet âgé et le troisième est lié aux particularités de Covid-19. Dans cette mise au point, nous soulignons les modifications liées au vieillissement pulmonaire physiologiques et leur rôle dans l’aggravation de la maladie covid19 chez le sujet âgéTéléchargements
