1 Characterization of Persistent Pulmonary Abnormalities Following COVID-19 Pneumonia

Severe Acute Respiratory Syndrome SARS-CoV-2, name of the Coronavirus Group of international Committee on taxonomy of viruses, is an emerging virus from the family of coronaviridae, responsible for the COVID-19 pandemic. This infection can progress to viral pneumonia, and in 3% of cases up to acute respiratory distress syndrome (ARDS) which conditions the prognosis of the disease. Due to its unusual clinical presentation with a risk of sudden deterioration on the 8th day as a result of possible hyperinflammatory response, the respiratory impairment of COVID is unique and many questions remain unanswered concerning its evolution once the acute phase has passed. Knowledge of the evolution of pulmonary involvement, particularly in patients requiring hospitalization, can help reduce the morbidity linked to the persistent abnormalities identified by establishing early therapeutic management. It can also provide a better understanding of the mechanisms of pulmonary involvement in the acute phase. Current data regarding the acute phase of COVID-19 suggest that persistent abnormalities remain distant from this infection at all levels of the respiratory system: gas exchange, perfusion, ventilatory mechanics, and interstitial lung disease. The main objective is to characterize persistent gas exchange anomalies 4 months after documented COVID-19 pneumonia, resulting in oxygen desaturation and requiring hospitalization.

NCT04422613 Pneumonia, Viral Diagnostic Test: pulmonary anomalies 4 months after documented COVID-19 pneumonia
MeSH:Pneumonia, Viral Pneumonia
HPO:Pneumonia

Primary Outcomes

Description: Alteration of the DLCO test defined by a corrected DLCO value <70% of theoretical and / or desaturation in the 6 Minute Walk Test (loss of 4% or more of SpO2)

Measure: Alteration of the DLCO

Time: 4 month

Secondary Outcomes

Description: The mechanism of the alteration of gas exchanges will be specified by the analysis of the values obtained during the diffusing CO / NO test, at 4 month after COVID- 19 pneumonia

Measure: Mechanism of the alteration of gas exchanges

Time: 4 month

Description: The mechanism of the alteration of gas exchanges will be specified by the analysis of the other values obtained during the measurement of lung volumes in respiratory function tests at 4 month after COVID- 19 pneumonia

Measure: Measurement on lung volumes

Time: 4 month

Description: The mechanism of the alteration of gas exchanges will be specified by the analysis of the other values obtained during chest CT-scan at 4 month after COVID- 19 pneumonia

Measure: mechanism of the alteration of gas exchanges by chest scan

Time: 4 month

Description: The mechanism of the alteration of gas exchanges identified will be specified by the analysis of the other values obtained during pulmonary scintigraphy, at 4 month after COVID- 19 pneumonia :

Measure: mechanism of the alteration of gas exchanges by scintigraphy

Time: 4 month

Description: the existence of respiratory symptoms, defined by dyspnea, cough, sputum, haemoptysis, chest pain, sign of right ventricular failure, sleep disorders or a 6-minute walk test value <80% of theoretical, at 4 month after COVID- 19 pneumonia

Measure: Respiratory symptom

Time: 4 month

Description: the existence of persistent bronchial or ventilatory anomalies at 4 months, defined on current respiratory function tests (plethysmography, forced oscillometry test, diaphragmatic explorations, measurement of exhaled NO)

Measure: Bronchial or ventilatory anomalies

Time: 4 month

Description: Persistent respiratory anomalies at 4 months will be evaluated at 12 months of the acute episode by an appropriate paraclinical assessment : mechanism of the alteration of gas exchanges, Respiratory symptom and bronchial or ventilatory anomalies will be evaluated

Measure: Persistent respiratory anomalies

Time: 12 month
