Evaluation of Patient Reported Satisfaction and Clinical Efficacy of Insulin Glargine 300 U/mL Versus 100 U/mL in Patients With Type 1 Diabetes Using Flash Glucose Monitoring System

BACKGROUND AND AIMS: To analyze patient-reported satisfaction and clinical effectiveness of concentrated insulin glargine 300 U/mL (Gla-300) among patients with type 1 diabetes (T1D) using a flash glucose monitoring (FGM) system. METHODS: This comparative study was conducted among 86 patients with T1D (aged 14-40 years), who were treated with Glargine 100 U/mL (Gla-100) and switched to Gla-300 at day 1 (baseline). The following data were collected from each patient: demographic information, clinical parameters. and glycemic control markers. All patients completed the Diabetes Treatment Satisfaction Questionnaire (Arabic version). first at baseline and then after 12 weeks. A comparison was done for all the data recorded at baseline (on Gla-100) and after 12 weeks (on Gla-300) and subjected to analysis. RESULTS: Compared to patients treated with Gla-100, significant improvements were observed in the Gla-300 group, in terms of the ambulatory glucose profile (AGP) markers, such as percentage of time spent within the target range of the glucose levels (70-180 mg/dL) (P = .037). percentage which fell below the target (<70 mg/dL) (P = .027), and percentage of time spent (<54 mg/dL) (P = .043). Compared to Gla-100. patients treated with Gla-300 experienced significant improvements in the current treatment satisfactions (P = .047), convenient finding treatment recently (P = .034), and flexible finding treatment recently (P = .041). recommend the current treatment (P = .042) and satisfied to continue the current treatment (P = .035). CONCLUSION: Compared to the patients on Gla-100. patients treated with Gla-300 exhibited significant improvements in the AGP markers and degree of treatment satisfaction.
