The intensity of free radical processes and chaperone activity in the saliva of patients with type 2 diabetes.

Introduction: Saliva is a clinically informative biological fluid that contains many biomarkers, allowing multiple analyses to be performed.

Aim: The objectives of this study were the assessment of the serum and saliva levels of biochemical parameters and intensity of free radical processes in T2DM patients and the identification of the correlation between certain criteria.

Methods: This case-control study included 40 T2DM patients, which were compared with 40 healthy individuals.

Parameters of Oxidative Stress and Activity of Antioxidant Enzymes in the Saliva of Patients with Type 1 Diabetes Mellitus.

Glucose concentration in the saliva is increased in type 1 diabetes mellitus. This parameter directly correlates with markers of the disease in the blood serum. Increased concentration of 8-oxo-2'-deoxyguanosine (8-OHdG) and diene conjugates, markers of oxidative stress, and reduced activities of superoxide dismutase and catalase were also observed in this pathology.

Inflammation is associated with impairment of oxidative status, carbohydrate and lipid metabolism in type 2 diabetes complicated by non-alcoholic fatty liver disease.

Background: Non-alcoholic fatty liver disease (NAFLD) is accompanied by inflammation and impairment of the lipid metabolism. In addition, NAFLD is one of the major complications of type 2 diabetes associated with oxidative stress. Based on this, we evaluated the tumor necrosis factor alpha (TNF-α), nuclear factor κB (NF-κB), oxidative status rates, and analyzed its correlation with carbohydrate and lipid metabolism in patients with NAFLD and type 2 diabetes.

The effect of methylethylpiridinol addition to the therapy on the level of pigment epithelium-derived factor and oxidative status in patients with diabetic nephropathy: randomized controlled open-label clinical study.

Purpose: The diabetic nephropathy is associated with oxidative stress and increases in pigment epithelium-derived factor (PEDF) level in the patient's blood. For the first time, authors investigated the effect of methylethylpiridinol addition to the therapy on oxidative status and pigment epithelium-derived factor concentrations, and examined the relationship between these indicators and clinical markers of pathology development.

Methods: Study design: open label randomized controlled trial study.
