Increased oxidative stress and inflammation with uremia lead to the development of anemia. In this context, we aimed to investigate the relationship between Hb variability and oxidative stress and inflammation. Material and Method: The data of 114 patients followed by dialysis service of Gaziantep University were included in this study retrospectively. Myeloperoxidase (MPO), nitrotyrosine (NTY), total antioxidant capacity (TAC), interleukin-6 (IL-6), Hs-CRP, and plasminogen activator inhibitor-1(PAI-1) levels of the patients whom we divided into 6 groups according to their Hg variability were measured. A control group (n = 30) was also formed demographically and clinically appropriate to this group. Results: The mean MPO, NTY, IL-6, Hs-CRP, and PAI-1 levels were higher in the dialysis patients than in the control group, whereas TAC levels were lower. Prooxidant, inflammation and procoagulant activity levels were lower in the Group 6 (Hg>12) and the Group 3 (stable, Hg=11-12 gr/dl) but higher in wide Hg variable group (Group 5) and Group 1 (Hg <12 gr/dl). Discussion: Oxidative stress, inflammation, and procoagulant activity, which are associated with higher CVD and mortality were found to be high in wide Hg variable and anemic groups in patients who underwent dialysis. The present study has a valuable finding in terms of elucidating the possible mechanism of increased mortality in patients with wide variable Hg course.
