Evaluation of this state through the levels of pro-inflammatory cytokines [interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α)], and acute-phase proteins [C-reactive protein (CRP)] may help predict the risk of all-cause mortality and cardiovascular mortality in patients with chronic renal failure receiving hemodialysis [4,5]. This evidence concerns the gene IL6 and chronic kidney disease.
