Nitric oxide metabolites, leukocyte activation markers and oxidative status in dialyzed subjects.
<i>Aims:</i> Our purpose was to evaluate, in a group of 42 end-stage renal disease patients who regularly undergo hemodialysis, some indexes of leukocyte activation, nitric oxide metabolites (NOx) and other parameters that reflect the oxidative stress before and after a standard hemodialysis session. <i>Methods:</i> Elastase and myeloperoxidase (MPO) were determined by means of ELISA. The NO production was evaluated by a micromethod which measures the concentration of NOx. The oxidation of polyunsaturated fatty acids was evaluated in plasma by detection of thiobarbituric acid-reactive substances (TBARS). Total antioxidant status (TAS) was obtained using spectrophotom…
Chronic kidney disease and inflammation: Role of +896A/G pro-inflammatory polymorphism of TLR4 gene and Δ32 deletion of CCR5 gene
bstract Chronic inflammation seems implicated in the pathophysiology of chronic kidney diseases (CKD) and the development of its complications, such as cardiovascular diseases (CVD). Genes encoding inflammatory molecules are, hence, good candidates for CVD risk in haemodialysis patients (HD). We therefore evaluated whether +896A/G TLR4 polymorphism and CCR5A32 deletion are risk factors for CKD and CVD. We examined the two gene variants in 72 HD patients and in 125 controls from Sicily. No significant differences in the genotype distribution and allele frequencies of the two gene variants were observed between patients and controls. The same results were obtained by analysing the combined ef…
