Background and Aims

In 2018, the Russified version of Free Style Libre (FSL) was registered in the Russian Federation.

To evaluate the metabolic profile and satisfaction with the use of the Russified version of FSL in children.

Methods

During 3 months, 10 children were held FSL. The age of the children was 4.4-14.4 years (7 boys, 3 girls). Initial HbA1с values were 5.8-9.0%. At the beginning and the end of the study, time in range, HbA1c, insulin dose, survey of children and parents with an assessment of satisfaction with the monitoring were analyzed. Satisfaction was rated on a five-point scale, where 5 - fully satisfied.

Results

1. HbA1с — in 50% of cases increased by 0.2-0.5%, 50% decreased by 0.3-0.7% 2. Time in range - 60% of children increased their time in range, 20% did not change and 20% decreased. In 80% of observations, the frequency and duration of hypoglycemia decreased. In 60% of children, hyperglycemia time decreased, in 40% this time slightly increased. 3. Insulin requirement - there was a general trend towards a significant reduction in the requirement and total daily dose of insulin. 4. Survey of participants - Patients and parents were fully satisfied with the monitoring system in 60% of cases, and 40% were satisfied.

Conclusions

FSL allows improve the glycemic profile of children, increase time in range, reduce the frequency and duration of hypo and hyperglycemia. Participants were highly satisfied with the use of FSL and the main wish was to include a warning system.
