Supplementary Material for: Chronic Kidney Disease and Risk of Death from Infection

Background: Infection, bacteremia and sepsis are major sources of morbidity and mortality in patients with end-stage renal disease. This study sought to determine the association between predialysis chronic kidney disease (CKD) and infection-related mortality. Methods: We analyzed participants in the Third National Health and Nutrition Examination Survey (NHANES III). The study included adults ≧45- years-old without end-stage renal disease. Estimated glomerular filtration rate (eGFR) was categorized as ≧60, 45–59.9 and 2, and urinary albumin-to-creatinine ratio (ACR) as Results: Of 7,400 participants included in the study, 206 died from infections. Compared to individuals with eGFR ≧60 ml/min per 1.73 m2, infection-related mortality was higher for those with lower eGFR [adjusted HR = 1.36 (95% CI: 0.81, 2.30) and 2.36 (1.04, 5.38) for eGFR of 45–59.9 and 2, respectively; p trend = 0.06]. Compared to individuals with ACR Conclusions: Reduced eGFR and albuminuria are associated with increased risk for infection-related mortality. Efforts are needed to reduce its incidence and mitigate the effects of infections among individuals with CKD.
