Hemodiafiltration With Endogenous Reinfusion Improved Microinflammation and Endothelial Damage Compared With Online-Hemodiafiltration: A Hypothesis Generating Study.

Hemodiafiltration with endogenous reinfusion (HFR) after ultrafiltrate passage through a resin cartridge combines adsorption, convection, and diffusion. Our prospective single-center crossover study compared HFR and online-hemodiafiltration (OLHDF) effects on two uremic toxins and 13 inflammatory, endothelial status, or oxidative stress markers. After an 8-week run-in period of high-flux hemodialysis, 17 eligible stable dialysis patients (median age 65 years, 10 male) without overt clinical inflammation were scheduled for four 8-week periods in the sequence: HFR/OLHDF/HFR/OLHDF.

Efficiency of Original versus Generic Intravenous Iron Formulations in Patients on Haemodialysis.

Aims: The appropriate use of intravenous (i.v.) iron is essential to minimise the requirements for erythropoiesis-stimulating agents (ESAs).

Effectiveness of haemodiafiltration with ultrafiltrate regeneration in the reduction of light chains in multiple myeloma with renal failure.

Acute kidney failure in multiple myeloma (MM) occurs in 12%-20% of patients and is a poor prognostic factor for patient survival. Recent studies have shown that dialysis with a High-Cut-Off membrane (HCO) removes free light chains (FLC) effectively although with significant albumin loss. Other adsorption-based techniques, such as haemodiafiltration with ultrafiltrate regeneration by adsorption in resin (SUPRA-HFR), have not been studied.

Losartan prevents the development of the pro-inflammatory monocytes CD14+CD16+ in haemodialysis patients.

Background: The principal cause of mortality in haemodialysis (HD) patients is cardiovascular disease, which is linked to chronic inflammation. Recent studies have demonstrated that angiotensin II receptor AT1 antagonists have anti-inflammatory properties. In this study, we evaluated the effect of losartan on CD14+CD16+ monocytes in HD patients.

Effects of intravenous iron on mononuclear cells during the haemodialysis session.

Background: This study analysed, in vivo and in vitro, the effects of four different intravenous iron preparations (iron gluconate, iron sucrose, iron dextran and ferric carboxymaltose) on activation and damage of mononuclear cells.

Methods: A randomized prospective study was conducted in 10 haemodialysis (HD) patients. Blood samples were collected at baseline (T0); 1 h after starting HD, just before the iron or saline administration (T1); 30 min after the iron or saline infusion (T2) and at the end of HD (T3).

CD14+CD16+ monocytes from chronic kidney disease patients exhibit increased adhesion ability to endothelial cells.

Chronic kidney disease (CKD) patients present an inflammatory process that induces endothelial damage and therefore plays a role in the high rates of cardiovascular morbidity and mortality reported in these patients. Although new therapies have reduced the elevated serum levels of inflammatory mediators such as cytokines and CRP in CKD patients, the rise in the level of activated immunocompetent cells is maintained in peripheral blood, which appears to play a prominent role in the endothelial damage suffered by these patients. CD14+CD16+ monocytes are a subset of activated monocytes that are found in greater numbers in the peripheral blood of CKD patients.

The imbalance in the ratio of Th1 and Th2 helper lymphocytes in uraemia is mediated by an increased apoptosis of Th1 subset.

Background: In uraemia there is a reduction in the total number of T lymphocytes and an imbalance in the ratio of Th1/Th2 T-helper (Th) lymphocytes. A higher rate of apoptosis in T lymphocytes has been reported in haemodialysis patients. The aims of the present study were to assess the Th1/Th2 pattern in uraemia and to evaluate whether a relative increase in Th1 apoptosis may explain the Th1/Th2 imbalance observed in uraemic patients.
