Chronic inflammation may be one of the factors that contribute to the development of diabetic nephropathy (DN). However, erythropoiesis, erythrocyte circulatory half-life and erythrocyte deformability may be influenced by inflammation. Thus, red blood cell distribution width (RDW) levels increase in inflammatory conditions. We investigated the RDW values and related factors in patients with uncomplicated type 2 diabetes mellitus (DM) and diabetic patients with DN. We carried out a retrospective study on patients with type 2 DM admitted to our hospital. Subjects were divided into three groups. Group 1 consisted of healthy subjects. Group 2 consisted of patients with uncomplicated type 2 DM. Patients with various stages of DN were included in Group 3. The RDW values in group 1 subjects were significantly lower than those in group 2 and 3 patients (p

BackgroundIt has become evident that gadolinium-based contrast agents (GBCA) may have nephrotoxic potential. Oxidative stress is one of the most important pathways in the pathogenesis of iodinated contrast-induced nephropathy.PurposeTo investigate the effects of static magnetic fields and gadopentetate dimeglumine (Magnevist®) on oxidant/antioxidant status via measurement of total antioxidant capacity (TAC), total oxidant status (TOS), and serum malondialdehide (MDA).Material and MethodsTwo age- and sex-matched groups of patients not under oxidative stress conditions that underwent magnetic resonance imaging (MRI) were recruited to this study. While contrast-enhanced (Magnevist®, 0.2 mmol/kg) MRI was performed in group 1, MRI without GBCA was performed in group 2. Fasting blood glucose, C-reactive protein, serum creatinine, liver enzymes, uric acid, and lipid parameters were examined in all patients. Peripheral venous blood samples in order to determine TAC, TOS, and MDA were collected before and 6, 24, and 72 h after the MRI procedures. The TOS:TAC ratio was used as the oxidative stress index (OSI). Patients were followed up to 72 h.ResultsThere were no significant changes in serum TAC, TOS, and MDA levels (Δserum TAC, Δserum TOS, and ΔMDA) in either group 6, 24, or 72 h after the procedures (P > 0.05). Furthermore, OSI did not change after the procedures in either group (P > 0.05).ConclusionMagnetic field and gadopentetate dimeglumine (Magnevist®) do not change the oxidant or antioxidant status at a dose of 0.2 mmol/kg.

Introduction: Mean platelet volume (MPV) is an independent cardiovascular disease predictor, and characteristics of MPV in patients with diabetic nephropathy (DN) are not well known. Aim: To determine the MPV levels in patients at different stages of DN. Patients and Methods: The MPV levels were investigated in healthy participants (group 1, n = 157), patients with type 2 diabetes mellitus without complication (group 2, n = 160), diabetic patients with clinical proteinuria (group 3, n = 144), and in patients with chronic kidney disease due to DN (group 4, n = 160). Findings: The MPV level was higher in all diabetic patients than that in normal participants ( P < .05). The MPV values had a positive correlation with the serum creatinine and proteinuria, and a negative correlation with the glomerular filtration rate ([GFR] P < .001 for all, r values; .72, and .82, and −.92, respectively). Conclusion: The MPV values were higher in diabetic groups than that in normal participants. Both GFR and proteinuria were the most powerful determinants of MPV.
