Serious pneumonia is a serious inflammation of the lungs caused by various pathogens, resulting in severe bacteraemia or toxemia, which in turn causes blood pressure drop, shock, blurred consciousness, restlessness, delirium and coma, etc., and requires intensive care and treatment in intensive care unit (ICU) because of its seriousness. There is an upward trend in the number of clinically immunosuppressed host patients, including long-term use of glucocorticoids for rheumatoid immune diseases and kidney diseases, tumor chemotherapy, organ transplantation, etc. A huge risk for these patients is the diagnosis and treatment of infections, especially lung infections. We have previously observed a significant increase in mortality from severe pneumonia in immunosuppressed patients, and our recent analysis of 204 patients with novel coronavirus pneumonia found that low lymphatic counts, immunosuppression, etc. were independent risk factors for death in patients. Early diagnosis and timely treatment are the main means to reduce the mortality rate of severe pneumonia. CD55 is an important complement regulatory protein that inhibits C3 and C5 activation by blocking the formation and accelerating the decay of new C3 and C5 convertases, both of which mediate the downstream action of all three complement activation pathways, and CD55 protects host cells from complement attack. Our previous study found that CD55 was significantly elevated in patients with severe pneumonia. Therefore, this project proposes "Early diagnosis of severe pneumonia based on combination of biomarkers with new generation pathogenesis and early clinical manifestations". It is proposed to validate the predictive effects of recently discovered markers such as CD55, HBP and CD64 on severe pneumonia through prospective single-center clinical studies, explore the establishment of new predictive models for early diagnosis of severe pneumonia, and optimize the diagnosis and treatment strategy of severe pneumonia, and provide new ideas for accurate treatment of severe pneumonia.
