新型冠状病毒、流感病毒和腺病毒肺炎的临床特征的比较OA

Objective To explore the unique clinical characteristics of several common types of viral pneumonia and clarify that these characteristics are of great significance for early diagnosis and treatment.Methods A retrospective analysis was con-ducted on the clinical data of 224 patients with pneumonia clinically diagnosed as caused by COVID-19,influenza viruses(Type A and Type B),and adenovirus infections.Data statistics and comparative analyses were performed with Excel and SPSS soft-wares.Results The inpatients with COVID-19 were mainly elderly people.Adenovirus infection was more common among young and middle-aged people.Among patients with influenza A and adenovirus infection,the proportion of those with a body tempera-ture exceeding 39 ℃ was relatively high.Patients with influenza B and adenovirus infection often had symptoms of the central nervous system,such as dizziness and headache.The lymphocyte count of patients with COVID-19 was significantly decreased,and the level of alkaline phosphatase was relatively low,but still within the normal range.However,alanine aminotransferase was elevated when patients with adenovirus pneumonia were admitted to the hospital.Radiologically,COVID-19 was characterized by thickening of small blood vessels and subpleural distribution.Most patients with influenza had exudative inflammation,and wedge-shaped fillings often occurred under the pleura.Adenovirus pneumonia was manifested as thickening of the bronchial wall,ground-glass opacity accompanied by consolidation.In addition,there were certain differences in the composition of pathogens that caused co-infection with different viruses.Conclusion Different types of viral pneumonia have certain specificity in clinical manifestations.
