- Abstract
Treating uridine as a product of UTP degradation and hypoxanthine as a degradation product of ATP, we assessed the concentration of uridine and hypoxanthine in the blood of children with newly diagnosed type 1 diabetes. We also sought to define the relationship between indicators of the degree of metabolic control of diabetes (fructosamine, HbA1c) and the concentration of the tested catabolites. This study was carried out on 33 children aged 12.26 ± 4.49 with newly diagnosed type 1 diabetes during their first hospitalization. The concentration of uridine and hypoxanthine was determined by high-performance liquid chromatography (HPLC). The results showed significantly elevated levels of hypoxanthine and uridine in the blood. We further show that blood uridine level is associated with purine metabolism and hyperglycaemia, and we demonstrate a significant positive correlation between the concentration of uridine and (i) the percentage of HbA1c and (ii) fructosamine levels, which indicate the role of hyperglycaemia in the pathogenesis of pyrimidine nucleotide metabolism in type 1 diabetes prior to diagnosis. The results confirm the existence of a relationship between the degree of metabolic control of diabetes and pyrimidine metabolism. Presumably, the analysis of uridine could be used as an adjunct marker of the severity of diabetic complications in newly diagnosed patients.
