Abstract:
Objective:To investigate high mobility group protein 1(HMGB1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)levels and their clinical significance in elderly patients with viral pneumonia.Methods:One hundred and sixty elderly patients with viral pneumonia admitted to the Sixth Hospital Affiliated to Anhui Medical University were enrolled as research subjects.In addition, 40 elderly people who underwent regular physical examination were considered as the control group.Patients with viral pneumonia were divided into the low-risk group, middle-risk group and high-risk group according to CURB-65 scores and pneumonia severity index(PSI)scores.HMGB1, TNF-α and IL-6 levels were compared between different groups.The correlations of CURB-65 scores and PSI scores with HMGB1, TNF-α, IL-6 levels were analyzed.Multivariate Logistic regression analysis was used to examine influencing factors for the severity of viral pneumonia in elderly patients.Results:HMGB1, TNF-α and IL-6 levels were higher in research subjects than in the control group.As the severity of viral pneumonia increased, so did HMGB1, TNF-α and IL-6 levels(all P<0.05). HMGB1, TNF-α and IL-6 levels in the severe viral pneumonia group were significantly higher than those in the non-severe viral pneumonia group( P<0.05). HMGB1, TNF-α and IL-6 levels were positively correlated with CURB-65 scores and PSI scores(CURB-65 score: r=0.463, 0.392 and 0.497, P=0.015, 0.003 and 0.025; PSI score: r=0.596, 0.515 and 0.381, P=0.007, 0.011 and 0.009). HMGB1, TNF-α and IL-6 levels were influencing factors for the severity of viral pneumonia in elderly patients( OR=1.344, 1.422 and 1.351, P=0.006, 0.015 and 0.009). Conclusions:HMGB1, TNF-α and IL-6 levels are closely correlated with the severity of viral pneumonia and are helpful for early assessment of viral pneumonia.
