title: C-reactive protein measurements as a marker of the severity of chronic obstructive pulmonary disease exacerbations.
abstract: Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease of the lungs. Acute exacerbations of COPD (AE-COPD) are a result of infectious or non-infectious instances. In our study, we aimed to determine whether serum C-reactive protein (CRP) levels are predictive indicators for disease severity and prognosis in hospitalized patients with AE-COPD. A total of 64 patients (36 regular ward and 28 ICU patients) were included in the study. Cases were identified and classified according to the Global Initiative for COPD. The first CRP test levels at acceptance at the ward or intensive care unit were counted in the study. CRP levels of patients in intensive care were significantly higher than those of patients in the regular ward. Mean values of CRP were detected to be 6.28 ± 6.53 mg/dl in the regular ward cases and 16.9 ± 12.03 mg/dl in the ICU patients (p < 0.01). The stage of COPD did not indicate a significant difference in terms of CRP values. Mean CRP values were found to be 16.02 ± 6.95 mg/dl in mortal cases and 9.76 ± 11.09 mg/dl in survivors (p < 0.01). High CRP levels were considered as a prognostic parameter and indicator of severity of AE-COPD. Increased mortality risk was found to be associated with high CRP values.
