Analysis of the different clinical characteristics between influenza virus pneumonia and bacterial pneumonia / 中国基层医药

ABSTRACT

Objective:To analyze the difference of clinical characteristics between influenza virus pneumonia and bacterial pneumonia.Methods:The clinical data of 112 patients with influenza virus pneumonia and bacterial pneumonia in Shengjing Hospital Affiliated to China Medical University from November 2018 to April 2019 were retrospectively analyzed.In accordance with the inclusion and exclusion criteria, 40 cases in influenza viral pneumonia group, and 72 cases in bacterial pneumonia group.The clinical data of age, underlying disease, respiratory rate, blood lymphocyte count, oxygen and index, chest CT imaging changes were analyzed in the two groups.Logistic regression was used to analyze the risk factors of influenza virus pneumonia.Results:Compared between the influenza virus pneumonia group and the bacterial pneumonia group, the differences in the age[(48.45±16.28)years vs.(59.18±19.11)years] and the oxygenation index[(267.5±90.7)mmHg vs.(368.6±47.6)mmHg] were statistically significant( t=-2.997, -6.563, all P<0.01). The changes of chest CT images with ground-glass opacity and involvement of multiple lobars were risk factors for influenza virus pneumonia( OR=12.491, 20.001, all P<0.05). Conclusion:The young and middle age, low oxygenation index, the CT images of chest with ground-glass opacity, and the multi-lobar distribution of lesions are risk factors for influenza virus pneumonia.
