Summary

The acute lung injury caused by SARS and 2003 were both related to the inflammatory cytokine storm in patients. The biochemical test showed abnormal increase in related indicators such as interleukin-8, and CT images showed a medical "white" lung". According to the experience of SARS treatment in 2003, the use of hormones will indeed help the patients to alleviate their illness, but patients who survived SARS either had too much hormone at that time and took too long. Although the lungs could recover, but the femoral head was necrotic Either the amount of hormones was very conservative at the time, which kept the lungs in the storm of inflammatory factors, leading to the emergence of irreversible pulmonary fibrosis. So is there a medicine that can anti-inflammatory, reduce the load of hormone use, and have the effect of treating and preventing pulmonary fibrosis complicated by severe viral lung? At present, pirfenidone has achieved encouraging results in the treatment of idiopathic Pulmonary Fibrosis (CTD-ILD) diseases. It is particularly encouraging that the values announced at the 2019 ATS Annual Conference suggest that pirfenidone has more anti-inflammatory and anti-oxidant effects than its own outstanding anti-fibrotic ability. The data shows early use, Its strong anti-SOD activity can effectively inhibit IL-1beta and IL-4, and can open the prevention mode of pulmonary interstitial fibrosis. Based on the above, this project intends to make the following scientific assumptions: based on the homology of the pathogens of the new coronavirus-infected pneumonia and the coronavirus infection of pneumonia in 2003, the similarities in the occurrence and development of the disease, that is, the pulmonary inflammatory storm occurs first, and thereafter The progress of fibrosis and the progressive decline of lung function and mortality are higher than those of ordinary pneumonia. We hope that by adding pirfenidone as a treatment program in addition to standard treatment, it will be a new and severe type of coronavirus infection. Patient clinical treatment provides an effective and practical method.

Criteria

Inclusion Criteria:

(1) Age ≥ 18 years. (2) Clinically diagnosed patients with new type of coronavirus pneumonia include: on the basis of meeting the criteria for suspected cases, one of the following pathogenic evidence: ① real-time fluorescent RT-PCR of respiratory specimens or blood specimens for detection of new coronavirus nucleic acid; Respiratory or blood specimens are genetically sequenced and highly homologous to known new coronaviruses. (3) The time interval between the suspected neocoronary pneumonia pneumonia case and the random enrollment is determined within 4 days to 7 days according to the history symptoms and chest CT imaging. Cough, diarrhea, or other related symptoms can be used. The imaging changes are mainly based on chest CT.
