Kim HW, Kim SH, Kim YO, Jin DC, Song HC, Choi EJ, Kim YL, Kim YS, Kang SW, Kim NH, Yang CW, Kim YK.   Perit Dial Int.   2014 Oct 7;

Zoungas S, Chalmers J, Neal B, Billot L, Li Q, Hirakawa Y, Arima H, Monaghan H, Joshi R, Colagiuri S, Cooper ME, Glasziou P, Grobbee D, Hamet P, Harrap S, Heller S, Lisheng L, Mancia G, Marre M, Matthews DR, Mogensen CE, Perkovic V, Poulter N, Rodgers A, Williams B, MacMahon S, Patel A, Woodward M, ADVANCE-ON Collaborative Group.   N Engl J Med.   2014 Oct 9;371(15):1392-406

In this 6-year follow-up study of patients enrolled in ADVANCE, there was no evidence that intensive glucose control during the trial led to long-term benefits with respect to mortality or macrovascular events. Though event rates were small, there was a reduction in end-stage renal disease in those patients in the intensive glucose arm, hazard ratio 0.54; […]

In this RCT, patients with ANCA-associated vasculitis who achieved complete remission after a cyclophosphamide-glucocorticoid regimen were randomly assigned to receive intermittent rituximab (days 0 and 14 and at months 6, 12, and 18) or daily azathioprine until month 22.  Major relapse was less common in the rituximab arm than the azathioprine arm (5% vs 29%) […]

Blood Pressure in Early Autosomal Dominant Polycystic Kidney Disease

In patients with early PKD, dual blockage of the RAS system provided no advantage over ACE inhibitor alone.  Patients targeted to the standard blood pressure target (120/70 to 130/80 mm Hg) vs a low blood-pressure target (95/60 to 110/75 mm Hg) had reduced annual % increase in total kidney volume (6.6% vs. 5.6%, P=0.006) and more reduction in […]

Garg AX, Kurz A, Sessler DI, Cuerden M, Robinson A, Mrkobrada M, Parikh CR, Mizera R, Jones PM, Tiboni M, Font A, Cegarra V, Gomez MF, Meyhoff CS, VanHelder T, Chan MT, Torres D, Parlow J, Clanchet Mde N, Amir M, Bidgoli SJ, Pasin L, Martinsen K, Malaga G, Myles P, Acedillo R, Roshanov PS, Walsh M, Dresser G, Kumar P, Fleischmann E, Villar JC, Painter T, Biccard B, Bergese S, Srinathan S, Cata JP, Chan V, Mehra B, Wijeysundera DN, Leslie K, Forget P, Whitlock R, Yusuf S, Devereaux PJ, POISE-2 Investigators.   JAMA.   2014 Dec 3;312(21):2254-64

In this sub-study of the POISE-2 study, neither ASA or clonidine reduced the risk of acute kidney injury after non-cardiac surgery. Of note, aspirin increased the risk of major bleeding (which was associated with a greater risk of acute kidney injury).  As well, clonidine increased the risk of clinically important hypotension (which was associated with […]
