Background. A concern about the susceptibility of immunocompromised patients to the worldwide pandemic of coronavirus disease 2019 (COVID-19) has been raised. We aimed at describing COVID-19 infections in the French cohort of lung transplant (LT) patients. Methods. Multicenter nationwide cohort study of all LT recipients with COVID-19 diagnosed from March 1 to May 19, 2020. Recipient main characteristics and their management were retrieved. Hospitalization characteristics, occurrence of complications and survival were analyzed. Results. Thirty-five LT patients with a COVID-19 infection were included. Median age was 50.4 (40.6-62.9) years, 16 (45.7%) were female, and 80% were double-LT recipients. Infection was community-acquired in 25 (71.4%). Thirty-one (88.6%) required hospitalization, including 13 (41.9%) in the intensive care unit. The main symptoms of COVID-19 were fever, cough, and diarrhea, present in 71.4%, 54.3%, and 31.4% of cases, respectively. Extension of pneumonia on chest CT was moderate to severe in 51.4% of cases. Among the 13 critically ill patients, 7 (53.9%) received invasive mechanical ventilation. Thrombotic events occurred in 4 patients. Overall survival rate was 85.7% after a median follow-up of 50 days (41.0-56.5). Four of 5 nonsurvivors had had bronchial complications or intensification of immunosuppression in the previous weeks. On univariate analysis, overweight was significantly associated with risk of death (odds ratio, 16.0; 95% confidence interval, 1.5-170.6; P = 0.02). Conclusions. For the 35 LT recipients with COVID-19, the presentation was severe, requiring hospitalization in most cases, with a survival rate of 85.7%.
The MDS classification, established by a consensus of French experts in bronchoscopy, could represent a standardized, universally acceptable system to describe central airway complications after lung transplant.
These results suggest that prestent planning by noninvasive method of obtaining CT scan provides optimal stent size and position, possibly avoiding a diagnostic bronchoscopy and reducing complications. Further prospective study is needed to confirm these results because of limitation of this study's design.
Intravenous Ig post-LT achieved similar survival and CLAD-free survival in recipients with hypogammaglobulinemia as compared to those with normal IgG plasmatic rate. A randomized control trial is required to confirm benefic effects of IVIg and disentangle mechanisms, including protection from infections, acute cellular and humoral rejections in patients with hypogammaglobulinemia after LT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
