Diagnostic value of urea, creatinine and blood parameters in patients with pneumonia diagnosed with chronic obstructive pulmonary disease

Abstract

This study aimed to investigate the diagnostic value of urea, Background: creatinine and other blood parameters in patients with pneumonia diagnosed with chronic obstructive pulmonary disease (COPD) for the first time.In this retrospective study, patients who had been diagnosed Methods: with COPD for the first time and were diagnosed with pneumonia were included. A total of 193 patients were divided into three groups as COPD + pneumonia (n=123), COPD (n=36) and pneumonia (n=34).In total, 59 women (48.0%) and 64 men (52.0%) from the COPD + Results: pneumonia group, 13 women (36.1%) and 23 men (63.9%) from the COPD group, 21 women (61.8%) and 13 men (38.2%) from the pneumonia group were assessed. The mean age of the COPD + pneumonia group was 69.58±13.62, 66.28±12.55 for the COPD group and 53.97±19.72 for the pneumonia group. The highest values of C-reactive protein (CRP), urea, creatinine, white blood cells (WBC), neutrophils, eosinophils and hemoglobin were the highest in COPD + pneumonia group. CRP levels were significantly different between COPD + pneumonia group (p<0.05). The parameters urea, WBC and neutrophils were significantly different between COPD + pneumonia group and pneumonia group (p<0.05). There was a statistically significant difference between COPD and pneumonia groups in terms of neutrophils and eosinophils values (p<0.05). According to the results of receiver operating characteristic analysis, the diagnostic value of the urea parameter in determining the COPD + pneumonia group was not statistically significant (p>0.05). On the other hand, the diagnostic value of CRP, WBC and neutrophils values were statistically significant (p<0.05).Elevation in WBC and neutrophil values in patients Conclusions: diagnosed with pneumonia have an important role in diagnosis of COPD.

“…[12][13][14][15] Urea (ure) is produced when proteins break down in mammals' bodies. 16 Recent research has shown that measuring levels of urea in saliva can be used as an effective way to diagnose various illnesses such as kidney problems, 10,17,18 lung disease, [19][20][21] infections, 22,23 diabetes mellitus, 11,24,25 cancer, 26 hypertension, 25,27 and others. The current method for detecting salivary urea involves using absorption spectrometers.…”
