Diabetes mellitus is now the most common cause of new cases of end-stage kidney disease treated with kidney replacement therapy in Australia. In addition to the approximately 5000 Australians receiving maintenance dialysis or living with a kidney transplant as a consequence of diabetes, many die from untreated end-stage kidney disease due to diabetes (DM-ESKD) each year. For every Australian receiving renal replacement therapy due to diabetes, at least 50 others have earlier stages of diabetic kidney disease (DKD). ⋯ However, in contrast to the increasing prevalence of diabetes and early stages of DKD, recent trends in the incidence of DM-ESKD suggest that better management in the earlier stages of DKD has been successful in slowing rates of disease progression. Simultaneous improvements in use of renin-angiotensin inhibitors and improved glycaemic and blood pressure control are likely to be largely responsible for this trend. Primary prevention, maximizing early detection of DKD and optimal management of diabetes and kidney disease hold great potential to attenuate the future health burden attributable to DKD in Australia.

To describe renal replacement therapy (RRT) prescribing practices in Malaysian intensive care units (ICU), and compare this with previously published data from other regions. ⋯ CRRT was the first-choice modality used to treat AKI in critically ill patients. CVVH was the most common CRRT technique used, while other RRT modalities were used less frequently. Overall, RRT practices were similar to those observed in other regions, although the modality and settings used were slightly different, likely due to local availability.

Predictors of perioperative blood transfusions in patients with chronic kidney disease undergoing elective knee and hip arthroplasty.
Lower preoperative haemoglobin and older age pose a risk for perioperative allogeneic blood transfusions (ABT). The presence of chronic kidney disease (CKD) is associated with low haemoglobin, greater bleeding and ABT utilization. ⋯ CKD alone, in the absence of anaemia, does not predispose to increased risk of ABT or length-of-stay in patients with mild-to-moderate CKD undergoing elective joint surgery. However, low haemoglobin is associated with increased ABT utilization and increased length-of-stay. Considering that 1 in 4 patients undergoing elective hip or knee arthroplasty has CKD, optimal preoperative patient blood management may improve outcome in this population.

To evaluate the performance of urinary neutrophil gelatinase-associated lipocalin (uNGAL), kidney injury molecule, interleukin-18 and heat shock protein 72 for differential diagnosis between causes of acute kidney injury in kidney transplant recipients, especially immunological rejection. ⋯ The biomarkers tested are not useful in identifying immunological rejection as cause of acute kidney injury in kidney transplant recipients.

Sepsis has been shown to induce the expansion of CD4+CD25+ regulatory T cells (Tregs), and this paradoxical immune suppression has been suggested to be closely associated with the development of sepsis-induced organ dysfunction. In the present study, we aimed to investigate the possible link between immune suppression and the development of septic acute kidney injury (AKI). ⋯ These results suggest that immune suppression in sepsis may be closely linked to the development of AKI and that sCD25 or IL-10 may be useful as novel biomarkers for the development of septic AKI.
