Glycemic control parameters in children with type 1 diabetes treated with fast-acting insulin aspart domestic biosimilar by continuous subcutaneous infusion

Introduction. Type 1 diabetes (T1D) is a chronic autoimmune disease requiring constant insulin therapy under regular continuous monitoring of glycemic parameters. The use of domestic insulin bioanalogues in CSII therapy is currently not sufficiently covered in the literature. Aim. To evaluate glycemic control parameters in children with T1D treated with the domestic fast-acting insulin aspart biosimilar by CSII. Materials and methods. Retrospective study was carried out on the basis of K.A. Raukhfus center St. Petersburg State Medical and Biomedical Center VMT. Fifty-five children with T1D aged 6 to 17 years (mean age 12 ± 4) were examined, including 29 boys (52.7%, mean age 11 ± 3 years) and 26 girls (47.3%, mean age 13 ± 4 years). Insulin therapy was carried out by systems of CSII Glycemic parameters were monitored by continuous and flash glycemic monitoring systems. The center visits frequency was once a month. Results . During dynamic follow-up after 3 and 6 months, children showed statistically significant (p < 0.05) improvement in glycemic control parameters–decrease in HbA1c level from 8.0 ± 1.8% to 7, 1 ± 1.2% and 6.8 ± 0.6%, increase in TIR from 60.4 ± 20.6% to 71.5 ± 13.0% and 75.9 ± 9.4%, decrease in TAR from 31.1 ± 22.1% to 23.0 ± 12.8% and 20.3 ± 9.3%, decrease in TBR from 9.1 ± 8.2% to 5.8 ± 4.3% and 4.1 ± 1.8%, and decrease in CV from 40.0 ± 9.1% to 33.7 ± 6.7% and 32.5 ± 5.6%. Discussion. The use of domestic biosimilar insulin aspart in insulin pumps iis associated with significant improvement in glycemic control in children and adolescents with T1D. Dynamic observation together with therapeutic education contribute to the maintenance of the achieved parameters at a high level. Conclusions. Therapy with the domestic fast-acting insulin aspart biosimilar by CSII allows achieving target glycemic control in children with T1D.
