No previous research has examined these outcomes in children-adolescents with type 1 diabetes (T1D) who use instant scanning CGM (isCGM) starting within the first month after diagnosis. Aim: To evaluate the impact of isCGM early after diabetes diagnosis on metabolic control and quality of life (QoL), comparing a group who use it from the onset with another one who didn’t have the device during the first year. Subjects and methods: Patients who initiated isCGM within 1 month from T1D diagnosis were enrolled in group A; those who didn’t have the device during the first year were considered as control group (group B). HbA1c and total daily insulin were evaluated at 3 (T1), 6 (T2) and 12 (T3) months post-baseline (T0, diabetes onset), QoL after 1 year. In group A, we also recorded isCGM glucose metrics. Results: 85 patients were enrolled in group A and 67 patients in group B. In group A isCGM was well accepted during follow up: no patient dropped out; percentage of time with active sensor was in mean > 87%; number of scans/day remained stable. QoL was higher in group A than in group B in children (p<0.0001) and in parents (p 0.003). Group A presented lower HbA1c during the first year after diagnosis (p<0.001), and this data correlated with GMI, TIR and mean glucose. The mean±SD hypoglycemia duration decreased during follow-up and honeymoon period lasted more in group A than in B (p 0.01). Conclusions: Early use of isCGM, starting within the first month after diagnosis, improves metabolic control and QoL in pediatric patients with T1D.
