The study aimed to assess the functional state of the kidneys and to study the relationship of I/D polymorphism of the ACE gene with the stage of chronic kidney disease in children and adolescents of the Uzbek population with type 1 diabetes according to the new recommendations of K/DOQI (2012). We examined 120 children and adolescents with type 1 diabetes. Clinical, biochemical and genetic studies have been carried out. The study revealed that children with diabetes in the stage of compensation (НbА1с ≤7.5%) have CKD stages II (28.6%) and III (4.8%). The use of the new classification K/DOQI (2012) reveals a decrease in kidney function at earlier stages, in 61.9% of children and adolescents with type 1 diabetes, even at the NAU stage, a GFR of 80.6 ± 7.5 ml/min/1.73m², which corresponds to stage II of CKD and 16.7% have a GFR of 45.1 ± 9.5 ml/min/1.73m², which corresponds to stage III of CKD. Also, 28.6% of children and adolescents at the MAU stage have CKD II, 75.0% of CKD stage III, respectively. ACE I/D polymorphism is a molecular genetic marker of susceptibility to the development of CKD type 1 diabetes in children and adolescents.
