Visfatin has been associated with some inflammatory disease. This study aimed to compare plasma visfatin levels in patients with community-acquired pneumonia and healthy controls and to furthermore investigate the relationship between their concentrations and 30-day mortality in patients. Plasma visfatin concentrations were measured in 176 patients and 95 healthy controls. The admission visfatin levels were significantly increased in all patients, survivals and non-survivals with community-acquired pneumonia compared with healthy control individuals, associated with pneumonia severity index score, Acute Physiology and Chronic Health Evaluation II score, white blood cell count, and plasma C-reactive protein level, and identified as an independent predictor for 30-day mortality. Its predictive value was similar to those of pneumonia severity index score and Acute Physiology and Chronic Health Evaluation II score. However, visfatin did not statistically significantly improve the predictive values of pneumonia severity index score and Acute Physiology and Chronic Health Evaluation II score. Thus, higher plasma visfatin level correlates with disease severity and markers of system inflammation and represent a novel biomarker for predicting 30-day mortality in patients with community-acquired pneumonia.
