The efficacy of removable devices to offload and heal neuropathic plantar forefoot ulcers in people with diabetes: a single-blinded multicentre randomised controlled trial.

Non-removable offloading is the 'gold standard' treatment for neuropathic diabetic plantar forefoot ulcers. However, removable offloading is the common 'standard of care'. We compared three removable offloading devices for ulcer healing efficacy.

The association of chronic kidney disease and dialysis treatment with foot ulceration and major amputation.

Objective: The objective of this study was to investigate the risk of chronic kidney disease (CKD) stage 4-5 and dialysis treatment on incidence of foot ulceration and major lower extremity amputation in comparison to CKD stage 3.

Methods: In this retrospective study, all individuals who visited our hospital between 2006 and 2012 because of CKD stages 3 to 5 or dialysis treatment were included. Medical records were reviewed for incidence of foot ulceration and major amputation.

Distal renal tubular acidosis with multiorgan autoimmunity: a case report.

A 61-year-old woman with a history of pernicious anemia presented with progressive muscle weakness and dysarthria. Hypokalemic paralysis (serum potassium, 1.4 mEq/L) due to distal renal tubular acidosis (dRTA) was diagnosed.

Effects of sodium restriction and hydrochlorothiazide on RAAS blockade efficacy in diabetic nephropathy: a randomised clinical trial.

Background: Reduction of dietary sodium intake or diuretic treatment increases renin-angiotensin-aldosterone system (RAAS) blockade efficacy in non-diabetic nephropathy. We aimed to investigate the effect of sodium restriction and the diuretic hydrochlorothiazide, separately and in combination, added to RAAS blockade on residual albuminuria in patients with type 2 diabetic nephropathy.

Methods: In this multicentre, double-blind, placebo-controlled, crossover randomised trial, we included patients with type 2 diabetic nephropathy.

Test characteristics of the aldosterone-to-renin ratio as a screening test for primary aldosteronism.

Background: The aldosterone-to-renin ratio (ARR) is a widely used screening test for primary aldosteronism. Current guidelines recommend a cut-off value of 91  pmol/mU. Studies on its sensitivity, specificity, reproducibility and the role of medication have been conflicting.

Determinants of blood pressure reduction by eplerenone in uncontrolled hypertension.

Background: Add-on therapy with aldosterone receptor antagonists has been reported to lower blood pressure (BP) in patients with uncontrolled hypertension. We assessed potential predictors of this response.

Methods: In essential hypertensive patients with uncontrolled BP, despite the use of at least two antihypertensives, plasma renin and aldosterone concentrations and the transtubular potassium gradient (TTKG) were measured.

Impact of incidental renal artery stenosis on long-term mortality in patients with peripheral arterial disease undergoing vascular procedure.

Objective: In peripheral arterial disease (PAD), mortality is high. Incidental renal artery stenosis (RAS) is a predictor of mortality in PAD patients undergoing angiography. This might be relevant for risk-benefit assessment when vascular surgery is considered, both in terms of perioperative risk, and in terms of life expectancy.

Moderate dietary sodium restriction added to angiotensin converting enzyme inhibition compared with dual blockade in lowering proteinuria and blood pressure: randomised controlled trial.

Objective: To compare the effects on proteinuria and blood pressure of addition of dietary sodium restriction or angiotensin receptor blockade at maximum dose, or their combination, in patients with non-diabetic nephropathy receiving background treatment with angiotensin converting enzyme (ACE) inhibition at maximum dose.

Design: Multicentre crossover randomised controlled trial.

Setting: Outpatient clinics in the Netherlands.

Continuous ambulatory peritoneal dialysis after intra-abdominally placed synthetic mesh for ventral hernia repair.

Background: We present a unique experience with a patient who had undergone continuous ambulatory peritoneal dialysis (CAPD) after laparoscopic repair of ventral incisional hernia (LRVIH) with an expanded polytetrafluoroethylene (e-PTFE) mesh (DualMesh(®); WL Gore) and who later suffered from multiple episodes of CAPD-related peritonitis without any signs of mesh infection.

Methods: A 48-year-old man with an open abdominal aortic reconstruction in 1994 for occlusive arterial disease presented with an incisional ventral hernia. He underwent LRVIH using an e-PTFE mesh of 30×20 cm.

Effect of the urotensin receptor antagonist palosuran in hypertensive patients with type 2 diabetic nephropathy.

The urotensin system has been hypothesized to play an important role in the pathophysiology of diabetic nephropathy. In this multicenter, randomized, double-blind, placebo-controlled, 2-period crossover study, the effects of the urotensin receptor antagonist palosuran on urinary albumin excretion and blood pressure in hypertensive patients with type 2 diabetic nephropathy treated with a single blocker of the renin-angiotensin-aldosterone system were assessed. Patients with 24-hour albuminuria >0.

Prevention of acute kidney injury and protection of renal function in the intensive care unit. Expert opinion of the Working Group for Nephrology, ESICM.

Background: Acute renal failure on the intensive care unit is associated with significant mortality and morbidity.

Objectives: To determine recommendations for the prevention of acute kidney injury (AKI), focusing on the role of potential preventative maneuvers including volume expansion, diuretics, use of inotropes, vasopressors/vasodilators, hormonal interventions, nutrition, and extracorporeal techniques.

Method: A systematic search of the literature was performed for studies using these potential protective agents in adult patients at risk for acute renal failure/kidney injury between 1966 and 2009.

Stent placement in patients with atherosclerotic renal artery stenosis and impaired renal function: a randomized trial.

Background: Little is known about the efficacy and safety of renal artery stenting in patients with atherosclerotic renal artery stenosis (ARAS) and impaired renal function.

Objective: To determine the efficacy and safety of stent placement in patients with ARAS and impaired renal function.

Design: Randomized clinical trial.

Atherosclerotic renovascular disease and renal impairment: can we predict the effect of intervention?

Atherosclerotic renal artery stenosis (ARAS) is associated with hypertension, ischemic nephropathy, and high cardiovascular risk. We review the data on revascularization of the renal artery by percutaneous transluminal renal angioplasty (PTRA) and pharmacological therapy. In patients with severe ARAS and poorly controlled hypertension, PTRA can improve blood pressure control.

Incidental renal artery stenosis is an independent predictor of mortality in patients with peripheral vascular disease.

In patients with peripheral vascular disease (PVD), mortality is high and renal artery stenosis (RAS) is a frequent incidental finding. RAS carries a high risk for mortality, but whether incidentally discovered RAS is a risk factor for mortality is unknown. The prognostic impact of incidental RAS for mortality was studied in 550 consecutive patients who underwent intra-arterial digital subtraction angiography for PVD in a single center between 1997 and 2000.

Long-term effects of arterial stenting on kidney function for patients with ostial atherosclerotic renal artery stenosis and renal insufficiency.

It is uncertain whether renal artery stent placement in patients with atherosclerotic renovascular renal failure can prevent further deterioration of renal function. Therefore, the effects of renal artery stent placement, followed by patency surveillance, were prospectively studied in 63 patients with ostial atherosclerotic renal artery stenosis and renal dysfunction (i.e.
