Elevated levels of serum CDCP1 in individuals recovering from severe COVID-19 disease.

Background: COVID-19 survivors report residual lung abnormalities after discharge from the hospital. The aim of this study was to identify biomarkers in serum and induced sputum samples from patients after hospitalization for COVID-19.

Methods: Patients admitted to hospitals in Spain with laboratory-confirmed COVID-19 were recruited for this study.

Pulmonary long-term consequences of COVID-19 infections after hospital discharge.

Objectives: Coronavirus disease 2019 (COVID-19) survivors are reporting residual abnormalities after discharge from hospital. Limited information is available about this stage of recovery or the lingering effects of the virus on pulmonary function and inflammation. This study aimed to describe lung function in patients recovering from COVID-19 hospitalization and to identify biomarkers in serum and induced sputum samples from these patients.
