Unexpected and striking effect of heparin-free dialysis on cytokine release

Heparin (both unfractionated and low molecular weight) is not only a potent anticoagulant but also has many pleiotropic effects, some of which are mediated by cytokine release. We compared the effect of hemodialysis (HD) with enoxaparin as an anticoagulant and without systemic anticoagulation (heparin-grafted membrane—Evodial) on the release of monocyte chemoattractant protein 1...

The effect of nephrectomy on Klotho, FGF-23 and bone metabolism

Background Increased concentration of fibroblast growth factor 23 (FGF-23) and decreased levels of soluble Klotho (sKL) are linked to negative clinical outcomes among patients with chronic kidney disease and acute kidney injury. Therefore, it is reasonable to hypothesize that GFR reduction caused by nephrectomy might alter mineral metabolism and induces adverse consequences...

Liver disease vs systemic inflammation in haemodialysis patients

importance in maintenance HD patients. Further studies are needed before this new trait is definitely excluded. Medical University Bialystok Poland Email: Jacek Borawski Beata Naumnik Michal Mys liwiec

Enoxaparin but not unfractionated heparin causes a dose-dependent increase in plasma TGF-β1 during haemodialysis: a cross-over study

Background. Transforming growth factor-β1 (TGF-β1) is a multi-functional cytokine that presents as a mediator of the heparin's pleiotropic action. In this cross-over study, we compared the effects of enoxaparin and unfractionated heparin (UFH) used as anticoagulants during haemodialysis (HD) on plasma TGF-β1 levels and some platelet activation markers: platelet-derived growth...

Tissue factor and its inhibitor in human non-crescentic glomerulonephritis—immunostaining vs plasma and urinary levels

Background. Tissue factor (TF)—the most potent trigger of coagulation and emerging antiapoptotic, proliferative and angiogenic factor, along with its principal inhibitor (tissue factor pathway inhibitor, TFPI) are known to be involved in crescentic glomerulonephritis (GN). We studied the relationship between plasma and urinary levels as well as renal biopsy immunostaining of TF...

Striking increase in circulating hepatocyte growth factor during enoxaparin-anticoagulated haemodialysis

Different effects of enoxaparin and unfractionated heparin on extrinsic blood coagulation during haemodialysis: a prospective study

Background. Heparin inhibits prothrombotic tissue factor (TF) and releases its inhibitor, tissue factor pathway inhibitor (TFPI), from the endothelium, but repeated administration of heparin depletes vascular stores of TFPI. We studied the anticoagulant effects of unfractionated heparin (UFH) vs low‐molecular‐weight enoxaparin—used for thrice‐weekly maintenance haemodialysis (HD...

Renal function, proteinuria and ACE‐inhibitor therapy as determinants of plasma levels of endothelial markers

Endothelial dysfunction marker von Willebrand factor antigen in haemodialysis patients: associations with pre‐dialysis blood pressure and the acute phase response

Background. Increased plasma soluble von Willebrand factor antigen (vWF : Ag) level, a marker of vascular endothelial cell dysfunction, is a strong predictor of atherosclerotic cardiovascular disease (CVD) in the general population. We studied cross‐sectional associations between vWF : Ag level, prevalence of CVD, and related factors including pre‐dialysis arterial blood pressure...

Soluble thrombomodulin is associated with viral hepatitis, blood pressure, and medications in haemodialysis patients

Background. The level of soluble thrombomodulin (sTM), a traditional marker of endothelial injury, is also dependent on renal excretory function. We studied serum sTM in chronic haemodialysis (HD) patients to determine which factors are predictive of its levels in this population. Methods and results. sTM levels of 10.7 (5.72–30.7) ng/ml in 100 HD patients were higher than in 30...
