Multicenter Study Comparative Study
Long-term outcomes of end-stage kidney disease for patients with IgA nephropathy: A multi-centre registry study.
Clinical outcomes of patients with end-stage kidney disease (ESKD) receiving renal replacement therapy (RRT) secondary to IgA nephropathy (IgAN) have not been well described. ⋯ IgAN ESKD was associated with better dialysis and renal transplant outcomes compared with other forms of ESKD. The survival outcomes of ESKD patients with HSPN were worse than kidney-limited IgAN.

Acute kidney injury (AKI) is a common complication associated with high morbidity and mortality in hospitalized patients. One potential mechanism underlying renal injury is ischaemia/reperfusion injury (IRI), which attributed the organ damage to the inflammatory and oxidative stress responses induced by a period of renal ischaemia and subsequent reperfusion. ⋯ In this review, we examine the technique of remote ischaemic preconditioning (rIPC), which has been shown by several trials to confer organ protection by applying transient, brief episodes of ischaemia at a distant site before a larger ischaemic insult. We provide an overview of the current clinical evidence regarding the renoprotective effect of rIPC in the key clinical settings of cardiac or vascular surgery, contrast-induced AKI, pre-existing chronic kidney disease (CKD) and renal transplantation, and discuss key areas for future research.

This study aimed to evaluate the long-term outcome of patients after a severe episode of acute kidney injury (AKI) on survival and progression to chronic kidney disease (CKD) and to identify risk factors associated with these outcomes. ⋯ This study showed that AKI patients have high mortality after hospital discharge and age, diabetes, liver disease, and Cr value at the time of discharge were factors associated with long-term mortality. The risk factors for this progression to CKD were age, the presence of diabetes and the number of AKI episodes.

Approximately 30-40% of children with steroid sensitive nephrotic syndrome have frequently relapsing nephrotic syndrome (FRNS) or steroid-dependent nephrotic syndrome (SDNS). Mycophenolate mofetil (MMF) and tacrolimus (TAC) are often alternative treatment choices for these patients. ⋯ In combination with low-dose steroids, MMF or TAC presented similar efficacy in maintaining remission in children with FRNS/SDNS in the present study. Therapy with MMF or TAC is a promising strategy with a moderate risk of side effects in children who are steroid sensitive but have FRNS/SDNS.

Erythropoiesis-stimulating agents (ESAs) are all effective for renal anaemia in patients with chronic kidney disease (CKD). However, it was reported that the haemoglobin (Hb) concentration decreases to 8.4 g/dL during the initial phase of dialysis despite treatment with recombinant human erythropoietin (rHuEPO). This study compared Hb at the initiation of dialysis among patients treated with three different ESAs (rHuEPO, darbepoetin alfa [DA], and a continuous erythropoietin receptor activator [CERA]). ⋯ Long-acting ESAs may be more useful for predialysis patients with CKD because they do not attend hospital frequently, unlike haemodialysis patients.
