Clinical characteristics and risk factors of virus or influenza infection among the hospitalized pneumonia in COPD patients

We examined the risk factors and clinical characteristics contributing to bacterial co-infection with virus or influenza among the hospitalized pneumonia with COPD patients.Pneumonia in COPD patients were admitted to gachon university Gil Medical Center from 1 January 2013 to 30 August 2014. They were divided into 2 groups based upon the presence of virus or influenza. One hudred fifty four patients identified virus or influenza(Virus group). Three hundred six patients not identified virus or influenza(control group). Retrospectively, we analysed the clinical characteristics, the results of blood examination and lung function tests from medical records of both groups.Mean age of each group was 74.4±9.7 years in virus group and 72.0 ± 9.7 years in control group. Age and female ratio was significantly higher in virus group. Pack year, smoking history and tuberculosis history were significantly lower in virus group. Virus group have significantly higher level of Blood pressure, serum albumin, P, hemoglobin, stable FVC(%) and FEV1 (%). Virus group have significantly lower level of FVC(L), FEV1(L), FEV1(%) and lymphocyte when they hospitalized. The two groups have no significant difference in other clinical features: hypertenstion, diabetes mellitus, ischemic heart disease, survival, hosptital day, body mass index, weight.Age, female, smoking and tuberculosis history may be associated with virus or influenza infection among the hospitalized pneumonia with COPD patien...
