05). At higher programmed DNa (140-145 mEq/L), measured DNa was greater for the BB and F4008 machines by all methods (P < 0.05), but only by ISE for the F5008 (P < 0.05).

We noted a systematic bias in DNa delivery with measured DNa being greater than that programmed by our HD machines. The magnitude of the bias varied between machines and with DNa. Our results may help explain the diverse results reported in studies of DNa.

In systemic amyloidosis, the kidney is frequently affected and renal involvement has a major impact on survival. Renal involvement is clinically characterized by decreased estimated glomerular filtration rate (eGFR) and proteinuria. The two most common renal amyloidosis types are light chain-related amyloidosis (AL) and serum amyloid A (AA) amyloidosis. Standardized histopathological scoring of amyloid deposits is crucial to assess disease progression. Therefore, we aimed to validate the proposed scoring system from Rubinstein

. (Novel pathologic scoring tools predict end-stage kidney disease in light chain (AL) amyloidosis. Amyloid 2017; 24 205-211) in an independent patient cohort.

We attempt to reproduce the scoring system, consisting of an amyloid score (AS) and a composite scarring injury score (CSIS), in a multicentre AL and AA case series. Additionally, we analysed all renal amyloidosis kidney biopsies performed in the Netherlands between 1993 and 2012.

Similar to the original study, AS and CSInal biopsies.

Foods prone to deteriorate renal function are rich in fat and in phosphorus (P), but the interaction between these two factors is not well studied.

Detailed structural and ultrastructural histopathological studies were performed on the kidneys of rats fed different amounts of fat and P low (4%) fat (LF) and normal (0.6%) P (NP), LF and high (1.2%) P (HP), high (35%) fat (HF) and NP, HF and HP, and HF with low (0.2%) P (LP) for 28 weeks.

Glomeruli of the HF groups showed segmental areas of retraction, sclerosis and thickening of the Bowman's capsule and basal membranes, which were more accentuated in the HF-HP group. Ultrastructural lesions in the glomeruli also were prominent in rats fed HF, particularly in the HF-HP group, and included thickening of the capillary membrane, endothelial damage, mesangial matrix hypercellularity and podocyte effacement. P restriction reduced the severity of endothelial damage, mesangial matrix hypercellularity, thickening of capillary basement membrane and podocyte effacement. The kidneys of rats fed HP showed significant tubular atrophy and dilatation, focal tubular hyperplasia, thickening of the tubular basal membrane, interstitial edema, inflammation and calcification. All groups fed HF also showed tubular lesions that were more prominent in the HF-HP group. P restriction had a beneficial effect on inflammation and calcification.

Intake of both HF and HP damages the kidneys and their noxious effects are additive. HF intake was preferentially associated with glomerular lesions, while lesions related to HP intake were located mainly in the tubuli and in the interstitium.

In dialysis patients, non-adherence to oral cinacalcet adds complexity to the control of secondary hyperparathyroidism. The present study aims to evaluate the use of intravenous calcimimetic, etelcalcetide, in the control of secondary hyperparathyroidism in patients adherent and non-adherent to oral calcimimetics.

The Simplified Medication Adherence Questionnaire was used to identify non-adherence. Almost half of the patients were non-adherent to the treatment with cinacalcet. Twenty-five patients (15 non-adherent) were switched from cinacalcet to etelcalcetide and were followed-up monthly for 8 months.

Cinacalcet was discontinued for 1 week before the initiation of etelcalcetide. After this period, the serum PTH levels increased by2-fold in adherent patients, whereas it did not change in non-adherent patients suggesting that they were not taking the medication. Etelcalcetide progressively reduced serum parathyroid hormone (PTH) (mean ± standard deviation) from 818 ± 395 to 367 ± 289 pg/mL (P

<

0.001) in non-adherents, and from 496 ± 172 to 228 ± 111 pg/mL (P

<

0.01) in adherent patients with a mean dose of 7.0 ± 2.3 and 5.1 ± 1.2 mg in non-adherent and in adherent patients, respectively. Etelcalcetide increased the percentage of patients with PTH on target from 28% to 58%. Patients with serum calcium <8.4 mg/dL increased from 8% to 40%, although they remained asymptomatic. The percent of patients with serum phosphate on target increased from 40% to 65%.

The lack of adherence to cinacalcet is a possible cause of the apparent lack of response to oral calcimimetic. The use of etelcalcetide ensures compliance and control of secondary hyperparathyroidism in both non-adherent and adherent patients.

Current evidence is insufficient to determine the contribution of stent grafts as treatment in partially thrombosed aneurysms or residual wall-adherent thrombi in arteriovenous fistulae (AVFs) for haemodialysis. The overall purpose of this study was to analyse patency rates of post-interventional covered stent deployment in those cases. We also assessed if patency rates differed when fistulas were punctured through the stent during dialysis sessions.

We conducted a retrospective study between 2006 and 2014 analysing post-intervention primary patency rates using the Kaplan-Meier log-rank test. Multivariate Cox proportional regression models were performed to determine if cannulation within the stent graft area was a potential risk factor for occlusion, by adjusted hazard ratio (HR).

A total of 27 procedures were included in the study. Primary patency rates (%) after stent deployment at 3, 6, 12, 24, 36 and 72 months were, respectively total 59, 32, 32, 21, 11 and 5; stent puncture 53, 21, 21, 16, 5 and 0; and no stent puncture 80, 80, 80, 40, 40 and 40.
