[Clinical features of community-acquired pneumonia associated with acute kidney injury in elderly patients.]

The aim of the study was to determin the incidence, severity and prognostic significance of acute kidney injury (AKI) in elderly patients with community-acquired pneumonia (CAP). 122 older patients (≥60 years) with community-acquired pneumonia were examined. Acute kidney injury was diagnosed in 49 (40,2%) patients including 47 (95,9%) patients with AKI occurring prehospital. In patients with community-acquired pneumonia associated with acute kidney injury the clinical picture of AKI was harder. Also disturbance of consciousness, dyspnea, leg swelling, tachycardia, abnormal liver function tests such as hyperbilirubinemia and hypertransaminasemia were diagnosed more frequently in this group of patients. With the development of AKI increased in-hospital mortality: odds ratio of death among patients with CAP associated with AKI was 8,3 (95% CI 2,75-25,28). So, the development of AKI in elderly patients with CAP is an actual health problem requiring the development of preventive measures and drug therapy in patients with CAP and also mandatory monitoring of patients who have had acute kidney injury.
