Randomized Controlled Trial Comparative StudyCreatinine fluctuation has a greater effect than the formula to estimate glomerular filtration rate on the prevalence of chronic kidney disease.
Cases of chronic kidney disease (CKD) are defined by the estimated glomerular filtration rate (eGFR), calculated using the Modified Diet in Renal Disease (MDRD) or, more recently, the CKD Epidemiology Collaboration (CKD-EPI) formula. This study set out to promote a systematic approach to reporting CKD prevalence. ⋯ A standardised approach to reporting case finding would allow a better comparison of prevalence estimates. Using a single eGFR tends to inflate the reported prevalence of CKD by ignoring creatinine fluctuation; this effect is greater than the difference between MDRD and CKD-EPI.

Medically important venomous snakes in Latin America belong to the genus Bothrops, Crotalus, Lachesis and Micrurus. The Bothrops genus is responsible for the majority of accidents. ⋯ Snake venoms cause local and systemic damage, including acute kidney injury, which is the most important cause of death among patients surviving the early effects of envenoming by the Crotalus and Bothrops genuses. Venom-induced acute kidney injury is a frequent complication of Bothrops snakebite, carrying relevant morbidity and mortality.

Chronic kidney disease (CKD) is not a priority on the health agenda in Africa and it remains a 'forgotten condition'. Most people in Africa do not have access to dialysis or transplantation, if they develop end-stage renal disease. Cardiovascular disease (CVD) and HIV/AIDS enjoy a more prominent profile as a serious cause of morbidity and mortality, but despite the clear links of CVD and HIV with CKD, there has been a failure to highlight the link between chronic illnesses like diabetes, hypertension and HIV/AIDS and both CKD and CVD. ⋯ This is aggravated by shortages of both financial and human resources and failure to strengthen health systems managing chronic diseases. The result is that very few people in Africa with CKD are managed early or receive dialysis or transplantation. This article investigates some of the issues impacting on the recognition of CKD as a public health issue, and will also consider some factors which could make CKD a more prominent chronic disease in Africa.

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.

Randomized Controlled Trial Comparative StudyUrinary neutrophil gelatinase-associated lipocalin and progression of diabetic nephropathy in type 1 diabetic patients in a four-year follow-up study.
Neutrophil gelatinase-associated lipocalin (NGAL), a marker of renal tubular damage, predicts progression in non-diabetic chronic kidney. We evaluated urinary (u)-NGAL as a predictor of progression in diabetic nephropathy in type 1 diabetic (T1D) patients. ⋯ Elevated u-NGAL was not related to decline in GFR during a 4-year follow-up. Elevated u-NGAL was associated with the development of ESRD and death, but not after adjustment.
