ObjectiveTo investigate the role on adverse prognosis and risk factors of acute kidney injury (AKI) in hospitalized patients with chronic obstructive pulmonary disease (COPD). MethodsClinical data from hospitalized patients with COPD between January 2009 and June 2012 were studied retrospectively.AKI was diagnosed and classified by AKIN criterion. ResultsThree hundred and sixty-nine patients were enrolled,among whom 69(18.6%) were complicated with AKI.The patients with AKI were older,and had higher levels of hemoglobin,hematocrit value and sodium concentration,and higher rates of comorbidities of diabetes mellitus,proteinuria and shock,compared with the controls.Those with AKI had a 24.1% increased risk for ventilator,121.5% for intensive care,and 89.8% for death.And a higher AKI grade was related to a worse prognosis.The increased risk of AKI was 142.1% for every 5-year increase of age,155.7% for every 0.1 increase of hematocrit value,70.5% for every 0.1 increase of sodium concentration,and 49.1%,89.2%,148.2% and 685.7% for being complicated with proteinuria,coronary artery disease,diabetes mellitus and shock. ConclusionAKI is associated with adverse prognosis in hospitalized patients with COPD.Age,proteinuria,increased levels of hematocrit value and sodium concentration,and comorbidities of coronary artery disease,diabetes mellitus and shock are independent risk factors for AKI
Acute kidney injury (AKI) is characterized by a rapid decrease in renal function caused by different etiologies and can involve multiple organs and systems. AKI is a potentially reversible disease. However, it can also progress to chronic kidney disease (CKD) without proper treatment. The concept of acute kidney disease (AKD) is recently recommended as a derivative between AKI and CKD. At present, AKI still lacks specific drug treatment; therefore prevention and early diagnosis are crucial in AKI management. Due to the heterogeneity of the pathogenesis, the epidemiological features of AKI vary across nations and regions, so the strategies for prevention and control are different. This papers reports new progress of epidemiological features of AKI in different countries, so as to provide reference for assessing the disease burden and formulating public health policies.
