En gros, on a 80% de moins de fumeurs chez les patients Covid qu\u2019en population g\u00e9n\u00e9rale de m\u00eame sexe et de m\u00eame \u00e2ge\u201d, explique le Professeur de m\u00e9decine interne Zahir Amoura, qui a men\u00e9 l\u2019\u00e9tude, sur France Inter.<\/div>\n<div>D\u00e9but avril, des donn\u00e9es de l\u2019AP-HP allaient \u00e9galement dans ce sens, montrant que parmi les 11.000 patients hospitalis\u00e9s pour cause de Covid-19, 8,5% \u00e9taient fumeurs, alors que le taux de fumeurs quotidiens est de 25,4%.<\/div>\n<div><\/div>\n<div><strong>*Distribution de patchs de nicotine<\/strong><\/div>\n<div>Comme Zahir Amoura le pr\u00e9cise, c\u2019est lors d\u2019une rencontre fortuite avec Jean-Pierre Changeux que l\u2019id\u00e9e d\u2019\u00e9tudier l\u2019impact de la nicotine sur la maladie a germ\u00e9.

Mais \u00e0 cette th\u00e9orie s\u2019en oppose une autre: la nicotine pourrait ralentir la r\u00e9ponse immunitaire.<\/div>\n<div>Pour faire le tri, et une fois le feu vert des autorit\u00e9s obtenu, les chercheurs de la Piti\u00e9-Salpetri\u00e8re distribueront des patchs nicotiniques dans des dosages diff\u00e9rents, et \u00e0 plusieurs publics.
