Background Blood pressure ( BP ) varies over time within individual patients and across different BP measurement techniques. The effect of different BP targets on concordance between BP measurements is unknown. The goals of this analysis are to evaluate concordance between (1) clinic and ambulatory BP , (2) clinic visit-to-visit variability and ambulatory BP variability, and (3) first and second ambulatory BP and to evaluate whether different clinic targets affect these relationships.

Urine markers can quantify tubular function including reabsorption (α-1 microglobulin [α1m]) and β-2-microglobulin [β2m]) and protein synthesis (uromodulin). Individuals with tubular dysfunction may be less able to compensate to insults than those without, despite similar estimated glomerular filtration rate (eGFR) and albuminuria. Among Systolic Blood Pressure Intervention Trial (SPRINT) participants with an eGFR under 60 ml/min/1.

Background And Objectives: The Systolic Blood Pressure Intervention Trial (SPRINT) demonstrated that intensive BP lowering reduced the risk of cardiovascular disease, but increased eGFR decline. Serum parathyroid hormone (PTH) and fibroblast growth factor-23 (FGF23) concentrations are elevated in CKD and are associated with cardiovascular disease. We evaluated whether intact PTH or intact FGF23 concentrations modify the effects of intensive BP control on cardiovascular events, heart failure, and all-cause mortality in SPRINT participants with CKD.

Heparin and citrate are used as catheter lock solutions to reduce risk of catheter dysfunction and infection in hemodialysis. There is a paucity of data comparing these two locks in the short-term, inpatient setting. We compared the efficacy of 2.

An acute increase in the international normalized ratio (INR; a comparison of prothrombin time to monitor the effects of warfarin) over 3 in patients with chronic kidney disease (CKD) is often associated with an unexplained acute increase in serum creatinine (SC) and an accelerated progression of CKD. Kidney biopsy in a subset of these patients showed obstruction of the renal tubule by red blood cell casts, and this appears to be the dominant mechanism of the acute kidney injury. We termed this warfarin-related nephropathy (WRN), and previously reported cases of WRN only in patients with CKD.

Hemodialysis requires reliable and recurrent access to the central circulation and arteriovenous fistulas or grafts are the preferred modes of vascular access. However, in many patients the use of external tunneled vascular catheters may be necessary. The major complication of tunneled catheters is infection.

The aortic injection of adenoviral-microsphere complexes is a useful technique for in vivo gene transfer (transduction) to the glomerulus. In this approach, the appearance of the foreign transprotein in the glomerulus may result from glomerular cell gene transfer and local synthesis or hepatic cell transduction followed by synthesis, secretion, and deposition in the glomerulus. We postulated that glomerular expression of the foreign transgene was the result of glomerular cell transduction.
