Study on the Recovery of Pulmonary Function, Chest CT, Airway Microbiota, Hematologic, and Immune & Inflammatory Conditions in COVID-19 Rehabilitation Patients

Union Hospital, Tongji Medical College, Huazhong University of Science and Technology

The intent of this study was to examine the health status of individuals who had been confirmed with COVID-19 in the year after their recovery. Parameters studied included serum levels of SARS coronavirus 2 (SARS-CoV 2) IgG antibody, SARS-CoV-2 nucleic acid test, hematology indicators (blood routine, liver function, kidney function, myocardial enzymes, coagulation function, etc), lung function test, imaging data and airway microbiota data. In addition, we explored the systematic Immune & Inflammation in some of the individuals recovering from COVID-19.

About 20% of COVID-19 developed into a critical illness and about 2% died. The global epidemic continues to develop, but some patients in China have entered the rehabilitation period, which is accompanied by a large number of respiratory symptoms and pulmonary fibrosis, bringing serious harm to the country. Therefore, early accurate detection and prediction of the development trend of patients in rehabilitation period and targeted treatment measures for corresponding patients are the key to the success of COVID-19 rehabilitation period. It will play a key role in the stratified management of the post-epidemic situation, which is crucial to improve the quality of life of COVID-19 patients. We aim to explore the clinical characteristics of rehabilitation patients by detecting some indicators of patients in rehabilitation period, including serum IgG and IgM antibody of SARS-CoV 2, SARS-CoV-2 nucleic acid, hematology indicators (blood routine, liver function, kidney function, myocardial enzymes, coagulation function, etc), pulmonary function, chest CT imaging, systematic Immune & Inflammation states.
