RESUMEN
Background: Severe COVID-19 survivors may exhibit functional impairment, radiological sequelae and persistent symptoms at short to mid-term follow-up. Aim(s): To determine the trajectories of respiratory recovery after severe COVID-19, and factors that could influence it. Method(s): Prospective, multicentre, longitudinal cohort study of adult patients hospitalized for severe COVID-19 (LOS >= 7d, oxygen flow >= 3L), evaluated at 3 months from hospital discharge with conditional follow-up at 6 and 12 months. Result(s): 486 participants from 13 French hospitals were included (median age 61y;female sex 27%): 173 needed oxygen only, 96 required non invasive ventilatory support and 217 were intubated. 454 (93%) patients were evaluated at 3 months, whereas 294 (60%) and 163 (34%) were followed up at 6 and 12 months, respectively. At 3- months assessment, a restrictive lung defect, an altered diffusion capacity and significant radiological abnormalities were observed in 33%, 71% and 57% of the cases, respectively. In case of extended follow-up, FVC (% pred.) increased by 4 points at M6 and by 7 points at M12, in mean;DLCO (% pred.) by 5 and 7 points, respectively. Age, sex, obesity, immunodepression, chronic cardiac or respiratory disease, initial extension of pneumonia and mechanical ventilation over 14 days were associated with lung function at 3 months but not with respiratory trajectories from this time point. Conclusion(s): A systematic follow-up seems justified after a severe COVID-19, especially in patients with extensive radiological lesions during acute illness. Pulmonary function and residual radiological abnormalities may improve up to 1-year after hospital discharge. Covid-19 A.

RESUMEN
Introduction: Les survivants de formes severes a critiques de COVID-19 peuvent presenter des sequelles fonctionnelles et radiologiques et des symptomes persistants a distance de l'episode aigu justifiant un suivi prolonge. L'objectif de l'etude est de determiner les trajectoires de recuperation respiratoire apres un COVID-19 severe, et les facteurs qui pourraient l'influencer. Methodes: Etude de cohorte prospective, multicentrique, longitudinale de patients adultes hospitalises pour COVID-19 severe (duree d'hospitalisation >= 7 j, debit d'oxygene >= 3 L) ou critique (intubation), evalues (clinique, TDM, EFR, test de marche, questionnaires de symptomes et de qualite de vie) 3 mois apres leur sortie de l'hopital, avec un suivi ulterieur conditionnel a 6 et 12 mois. Resultats: Au total, 486 participants ont ete inclus dans 13 hopitaux francais (age median : 61 ans;sexe feminin : 27 %) : 173 avaient necessite de l'oxygene seul, 96 un support ventilatoire non invasif (CPAP, OHD ou VNI) et 217 avaient ete intubes. Au total, 454 patients (93 %) ont ete evalues a 3 mois, 294 (60 %) et 163 (34 %) ont ete suivis respectivement jusqu'a 6 et 12 mois. Une dyspnee d'effort, un syndrome restrictif, un trouble de la diffusion et des anomalies radiologiques significatives ont ete observees respectivement dans 62 %, 33 %, 71 % et 57 % des cas a M3. En cas de suivi prolonge, la DLCO (% theo.) et la CVF (% theo.) augmentaient en moyenne de +4 points a M6 et respectivement de +6 points et +7 points a M12. Le sexe, l'indice de masse corporelle, les maladies cardiovasculaires ou respiratoires chroniques, l'immunodepression, l'etendue de la pneumonie pendant la phase aigue de la maladie et la duree prolongee (> 14 j) de ventilation mecanique invasive etaient associes a la DLCO a M3, mais pas a sa trajectoire ulterieure. Parmi 476 patients (97,9 %) ayant eu au moins une TDM thoracique au cours du suivi, 196 (41 %) avaient des sequelles significatives sur leur derniere imagerie. Le sexe, l'etendue de la pneumonie a la phase aigue, la duree de la ventilation mecanique invasive et la DLCO a M3 etaient independamment associes au resume des composantes physiques du SF-36, tandis que seul l'age etait associe au resume des composantes mentales du SF-36. Conclusion(s): Bien que la fonction respiratoire s'ameliore et que les anomalies radiologiques residuelles regressent jusqu'a 1 an apres l'episode aigu, une proportion importante des survivants de formes severes ou critiques de COVID-19 ont des sequelles radiologiques et fonctionnelles importantes et des symptomes residuels pouvant affecter leur qualite de vie et justifiant un tel suivi.

RESUMEN
The objective of this document is to formalize a degraded mode management for patients with thoracic cancers in the context of the COVID-19 pandemic. The proposals are based on those of the French High Council for Public Health, on published data outside the context of COVID-19, and on a concerted analysis of the risk-benefit ratio for our patients by a panel of experts specialized on thoracic oncology under the aegis of the French-Language Society of Pulmonology (SPLF)/French-language oncology group. These proposals are evolving (10 April 2020) according to the situations encountered, which will enrich it, and are to be adapted to our institutional organisations and to the evolution of resources during the COVID-19 epidemic. Patients with symptoms and/or COVID-19+ are not discussed in this document and are managed within the framework of specific channels.
