Multicenter Study Comparative StudyEarly acute kidney injury is a risk factor that predicts mortality in patients treated with colistin.
The nephrotoxicity of colistin has been reported in the literature. A previous report has shown that acute kidney injury (AKI) occurred after an average of 13.5 days, but we have experienced that AKI developed with colistin administration earlier. We investigated clinical features of patients who developed AKI according to the time of AKI development after colistin use. ⋯ AKI occurred in 46 patients within 7 days after colistin treatment and in 19 patients after 7 days. The patients with early AKI had a higher mortality rate than those with late AKI (OR: 4.37, 95% CI: 1.34, 14.18). In conclusion, clinicians might be cautioned that the mortality rate is higher for the patients with early occurrence of AKI than that for the patients with late occurrence of AKI.

ReviewA gut feeling on endotoxemia: causes and consequences in chronic kidney disease.
Chronic inflammation is closely linked to several complications of chronic kidney disease (CKD), such as vascular calcification, accelerated atherosclerosis, loss of appetite, insulin resistance, increased muscle catabolism and anemia. As a consequence, inflammation is a predictor of mortality in this group of patients. ⋯ In this minireview, we propose that there are several potential sources of endotoxemia in CKD and that gut translocation, leading to the generation of ligands of the innate immune response, represents a potentially reversible cause. Prevention of endotoxemia, through treating foci of ET (periodontal disease, catheters, vascular access) or reducing translocation from the gut, will potentially reduce the inflammatory response.

Comparative StudyPrediction of mortality in patients undergoing maintenance hemodialysis by Charlson Comorbidity Index using ICD-10 database.
Many patients with end-stage renal disease have additional comorbidities that are important to clinical study and impact the patient's outcome. The Charlson Comorbidity Index (CCI) is a popular tool and a strong predictor of outcome in end-stage renal disease patients. We obtained comorbidity data from the hospital discharge database using the International Classification of Disease, 10th revision (ICD-10) and analyzed the mortality rate in incident patients undergoing maintenance hemodialysis (HD). ⋯ The CCI scores using the ICD-10 database information were significant predictors of mortality in incident patients undergoing maintenance HD.

Comparative StudySingle estimated glomerular filtration rate and albuminuria measurement substantially overestimates prevalence of chronic kidney disease.
Guidelines require repeatedly diminished estimated glomerular filtration rate (eGFR) and/or albuminuria to diagnose chronic kidney disease (CKD), and advise screening only in select populations. Many estimates of CKD prevalence have used single measurements. This longitudinal study assessed eGFR and albuminuria reproducibility, and impact on estimate of CKD prevalence, in factory workers. ⋯ Non-targeted screening for CKD is inaccurate and can overestimate prevalence. This study emphasises the importance of confirming abnormal eGFR and proteinuria on at least one further sample 3 months apart before categorising the individual as having CKD. This has wide implications for screening in European general populations.
