Clinical Trial Summary

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.

Description:

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pulmonary Function	Forced vital capacity (FVC), forced expiratory volume in one second (FEV1) for lung volume, peak expiratory flow (PEF) for velocity, carbon monoxide diffusion capacity (DLCO) for pulmonary diffusion function.	an average of 1 to 3 months after recovery
Primary	Chest CT	Percentage of lungs that contain reticular patterns, Percentage of lungs that contain pure ground-glass opacification, Percentage of lungs that contain honeycombing, Percentage of lungs that contain traction bronchiectasis, Percentage of lungs that contain strip-like consolidation.	an average of 1 to 3 months after recovery
Primary	Changes in hematology	blood routine indexes included leucocytes(×109/L), neutrophils(×109/L), lymphocytes(×109/L), monocytes(×109/L), eosinophils(×109/L), platelets(×109/L). Biochemical and coagulation function indicators included total protein(umol/L), creatinine (umol/L), uric acid (umol/L), lactic dehydrogenase(U/L), C-reactive protein (mg/L), aspartate aminotransferase (U/L), glutamic-pyruvic transaminase (U/L), D-dimer,(ug/L), fibrinogen(g/L), Active part thrombin time (APTT), prothrombin time (PT), thrombin time (TT) and troponin (TNI).	an average of 1 to 3 months after recovery
Primary	Changes in immune and inflammatory states	Immune cells and related cell factors included CD8+T cell(×109/L), CD4+T cell(×109/L), bone marrow derived suppressor cells(×109/L), regulatory T cells(×109/L), natural killer cell(×109/L), dendritic cell(×109/L), macrophages(×109/L), interleukin-4(IL-4)ug/L, IL-2 ug/L, IL-17 ug/L, IL-15 ug/L, IL-16 ug/L, IL-1 ug/L, IL-6 ug/L, IL-10 ug/L, tumor necrosis factor ug/L, interferon gamma ug/L, eotaxin-3 ug/L, eotaxin ug/L.	an average of 1 to 3 months after recovery
