Little data exist on outcome of acute kidney injury (AKI) in diabetes. We describe short-term recovery of renal function, patient mortality and progressive renal dysfunction following AKI in diabetic patients. ⋯ Although acute mortality is comparable following an AKI episode in diabetic patients compared with that associated with AKI in a non-diabetic cohort, for those surviving the acute episode, its impact on renal function is significantly less than in a non-diabetic group.

Comparative Study Observational Study
Association of serum sodium levels with all-cause and cardiovascular mortality in chronic kidney disease: Results from a prospective observational study.
The prevalence of hyponatraemia in the outpatient setting has not been thoroughly explored, and little is known about the prognostic implication of dysnatraemia in chronic kidney disease (CKD) patients, in particular accommodating the effect of concurrent medications. ⋯ Hyponatraemia in the ambulatory setting is associated with all-cause but not cardiovascular mortality in CKD, independent of concomitant medications and co-morbidities.

The use of cardiopulmonary bypass (CPB) can cause changes in serum creatinine and cystatin C independent of glomerular filtration rate. We aimed to quantify the temporal changes of these biomarkers and C-reactive protein (CRP) after CPB. ⋯ Serum creatinine and cystatin C appear not to be interchangeable biomarkers during and immediately after CPB. Processes unrelated to kidney function such as acute inflammation have a significant effect on post-CPB changes in these biomarkers, and may result in significant increases in serum cystatin C that could erroneously be interpreted as AKI.

Patients with chronic heart failure (CHF) are often characterized by the cardiorenal syndrome (CRS). The aim of the present study was to assess whether novel markers of kidney injury are able to predict progression of chronic kidney disease (CKD) in patients with CHF. ⋯ During long-term follow-up chronic heart failure patients with CKD show a relevant disease progression. The current study emphasizes a strong association of the tubular biomarkers NAG and KIM-1 with CKD progression in chronic heart failure and suggests their usefulness as cardiorenal markers.

Observational Study
Dipstick albuminuria and acute kidney injury recovery in critically ill septic patients.
Acute kidney injury (AKI) is a frequent complication of sepsis, a pro-inflammatory state that alters tubular handling of filtered albumin. We hypothesized that dipstick albuminuria (DA) is associated with a lower rate of AKI recovery in septic patients. ⋯ Dipstick albuminuria ≥30 mg/dL is independently associated with lower rate of AKI recovery at 30 days post-discharge. Our findings emphasize the potential utility of a simple routine test of DA in the risk-stratification of AKI recovery in ICU septic patients.
