Efficiency of Endothelial Dysfunction Correction with Methylethylpyridinol in Patients with Type 1 Diabetes Mellitus

Aim. To measure endothelial factors (nitric oxide (NOx) metabolites, endothelin-1 (ET-1), and basic fibroblast growth factor (bFGF)) in children and adolescentswith diabetes mellitus (DM) during development of diabetic peripheral polyneuropathy (DPNP). Materials and methods. A total of 130 children and adolescents with diabetes mellitus were examined. Duration of DM varied from 3 months to 14 years. Thecontrol group comprised 20 children and adolescents without DM or neurologic pathology. Subjective manifestations of DPNP were assessed based on thedata of a standardized Neuropathy Symptom Score (NSS) questionnaire. Neuropathy Disability Score (NDS) questionnaire was used to monitor objectivechanges of DPNP. NOx metabolites were detected with Griess reagent (Aldrich Chemical Co, USA). Serum ET-1 and bFGF were measured using solid-phaseimmunoenzyme assay (DRG, USA) and CYTIMMINE (USA) kits respectively. Results. All children and adolescents with DM1 had lower NOx and bFGF levels than controls. ET-1 level in DM patients was 3.5 times that in controls. DMpatients with DPNP had more pronounced endothelial dysfunction than DM patients without DPNP and control subjects. Patients with hyperproduction ofNOx had DM for more than 10 years and their total NDS score was significantly higher than in two other groups. Conclusion. Endothelial dysfunction in children and adolescents with type 1 diabetes mellitus progresses with the development of DPNP. Depletion of endothelialfunctional reserve is responsible for the unfavourable course of DPNP.

Diabetic kidney disease belongs to the major complications of diabetes mellitus. Here, hyperglycaemia is a key metabolic factor that causes endothelial dysfunction and vascular changes within the renal glomerulus. The aim of the present study was to assess the function of the vascular endothelium in children with type 1 diabetes mellitus (type 1 diabetes) by measuring selected endothelial lesion markers in blood serum. The selected markers of endothelial lesions (sVCAM-1, sICAM-1, sE-SELECTIN, PAI-1, ADMA and RAGE) were assayed by the immunoenzymatic ELISA method. The study involved 66 patients (age: 5–18 years) with type 1 diabetes and 21 healthy controls (age: 5–16 years). In the type 1 diabetes patients, significantly higher concentrations of all of the assayed markers were observed compared to the healthy controls (p < 0.001). All of the evaluated markers positively correlated with the disease duration, the age, and BMI of the patients, while only PAI-1 and sE-SELECTIN were characteristic of linear correlations with the estimated glomerular filtration rate (eGFR). It can be concluded that endothelial inflammatory disease occurs in the early stages of type 1 diabetes mellitus in children. The correlations between PAI-1, sE-SELECTIN, and eGFR suggest an advantage of these markers over other markers of endothelial dysfunction as prognostic factors for kidney dysfunction in children with type 1 diabetes.
