Abstract:
Objective:To assess the effect of flash glucose monitoring (FGM) compared with self-monitoring of blood glucose (SMBG) on glycemic control, residual islet function, and patient-reported outcomes in children and adolescents with newly diagnosed type 1 diabetes within 1 year.Methods:133 children and adolescents with newly diagnosed T1DM in the T1D clinic of the Second Xiangya Hospital of Central South University from January 2016 to January 2020 were divided into two groups: FGM group ( n=82) and SMBG group ( n=51). The observation indexes included hemoglobin A1c (HbA 1c), fasting and postprandial blood glucose (FBG and 2 h BG), C-peptide (FCP and 2 h CP) during the one-year follow-up, Δ CP (2 h CP-FCP), patient-reported hypoglycemia and questionnaires regarding self-management of diabetes and quality of life. Results:At 6 months, HbA 1c in 2 groups was significantly decreased (all P<0.05); at 6 to 12 months, HbA 1c in FGM group tended to be stable ( P>0.05); at 12 months, HbA 1c in SMBG group was significantly increased compared with 6 months ( P=0.001). At 12 months, HbA 1c in SMBG group was higher than that in FGM group ( P=0.001). At 12 months, FBG in FGM group was equivalent to the baseline level ( P>0.05), while FBG in SMBG group was significantly higher than the baseline level ( P=0.006). 2 h BG only decreased at the 6th and 12th month in FGM group (all P<0.05). The FCP of SMBG group was significantly decreased at 12 months ( P<0.05), and the 2 h CP, Δ CP in the two groups decreased gradually (all P<0.05). FGM group had more hypoglycemic events at 6 and 12 months (all P<0.05). At 6 months, the score of Self-Management of T1D for Adolescents (SMOD-A) in FGM group was significantly improved ( P=0.001). During the follow-up period, the quality of life score of FGM group was stable ( P>0.05), while the quality of life score of SMBG group had a downward trend ( P=0.052). Conclusions:In newly diagnosed children and adolescents with T1DM, early application of FGM for blood glucose management will help to improve HbA 1c and reduce postprandial blood glucose. In addition, the self-management ability of children with FGM was improved after 6 months.
