Early initiation of dialysis: mortality and renal function recovery in acute kidney injury patients.
The decision of when to start dialysis in Acute Kidney Injury (AKI) patients with overt uremia is strongly established, however, when blood urea nitrogen (BUN) levels is < 100 mg/dL the timing of initiation of dialysis remains uncertain. ⋯ Lower mortality and higher renal function recovery rates were associated with early dialysis initiated at lower BUN levels in AKI patients.

The recent RIFLE classification defines three degrees for severity of acute kidney injury (AKI): RISK, INJURY and FAILURE and was associated with mortality according to the grading of the severity of AKI, but little valued at prospective studies. ⋯ The severity of AKI according to RIFLE criteria was a risk marker for mortality in this population. The LRA group class Injury + Failure was associated with increased mortality when compared to the subgroup Without AKI + AKI that remained in Risk class even after adjustments for multiple variables.

Hypokalemia is found in peritoneal dialysis (PD) patients. The problem may be severe and promote mortality. Several factors may trigger the hypokalemia in PD patients, such as preexisting malnutrition and the low protein and potassium food intake. ⋯ Low levels of serum potassium were associated to lower survival in PD patients and it seems to be related to malnutrition.
