Purpose: Serum uric acid (SUA) is a novel risk factor for acute kidney injury (AKI), which adversely affects renal blood flow autoregulation, glomerular filtration rate (GFR), and promotes inflammation and angiogenesis. This pilot study investigated the effect of lowering SUA therapy on AKI, by using traditional and non-traditional markers.
Materials And Methods: In this prospective, double-blind, placebo-controlled, randomized pilot trial, 26 hyperuricemic patients undergoing cardiac surgery were randomized to receive rasburicase or placebo in the preoperative period.
Background: Previously, we reported that the prophylactic use of nesiritide did not reduce the incidence of dialysis or death following cardiovascular (CV) surgery despite reducing the incidence of acute kidney injury (AKI) in the immediate postoperative period. Therefore, we investigated whether the observed renal benefits of nesiritide had any long-term impact on cumulative patient survival and renal outcomes.
Methods: Participants of the Nesiritide Study, a previously reported prospective, double-blind, placebo-controlled, randomized clinical trial investigating the effect of nesiritide on the incidence of dialysis or death at 21 days in adult patients undergoing high-risk CV surgery, were included in the study.
Background: Uric acid has been reported to be a risk factor for the development of chronic kidney disease; however, no study has examined whether uric acid may confer a risk for acute kidney injury.
Methods: We investigated the relation between serum uric acid and the incidence of postoperative acute kidney injury in patients undergoing high-risk cardiovascular surgery (cardiac valve and aneurysm surgery).
Results: Following cardiovascular surgery, 18 of 58 patients (31%) developed acute kidney injury, with 11 of 24 (45.
Intra-abdominal hypertension (IAH), leading to abdominal compartment syndrome (ACS), is a frequent cause of acute kidney injury (AKI) in surgical and trauma intensive care units not commonly recognized by nephrologists. Multiple organ systems are often affected and frequently culminate in disastrous outcomes. The diagnosis of AKI as a manifestation of IAH requires a high index of clinical suspicion, especially, because laboratory and imaging studies are unreliable.
