Faster-acting insulin aspart reduces glycaemic variability in sensor-augmented pump treated type 1 diabetes patients.

AIM: To evaluate the effect of faster aspart over glycaemic variability in type 1 diabetes (T1D) patients treated with sensor-augmented pump (SAP) in a real-world scenario. METHODS: Observational study with SAP-treated adult T1D patients treated with faster aspart for three months. The primary endpoint was the mean amplitude of glucose excursions (MAGE). RESULTS: Fifty patients were treated with faster aspart. Eleven patients (23%) withdrew during the follow-up mainly due to worsening of diabetes control (9 patients). Mean age was 41.2 yrs. (range 21-59) and T1D duration 22.4±10.0 yrs. Mean SAP treatment duration was 3.6±3.1 yrs. We detected a reduction of -7.0 (95% CI -1.1, -12.9; p=0.021) in MAGE at the end of the study. Other glycemic variability indices were also improved: standard deviation of mean interstitial glucose (-3mg/dl; 95% CI, -1, -5; p=0.01), CONGA4 (-2.2; 95% CI -0.3, -4.2; p=0.029), CONGA6 (-2.6; 95% CI -0.6, -4.6; p=0.011), GRADE (-0.5; 95% CI -0.1, -0.9; p=0.022), HBGI (-0.7; 95% CI -0.2, -1.3; p=0.013), J-index (-2.9; 95% CI -0.7, -5.0; p=0.011) and MODD (-5.7; 95% CI -1.7, -9.7; p=0.006). A slight reduction in mean glucose management indicator was also detected (-0.14%; 95% CI, -0.02, -0.27; -1.4mmol/mol; 95% CI -0.1, -3.3; p=0.03). CONCLUSIONS: In SAP-treated T1D patients, faster aspart insulin was associated with reduced glycaemic variability, but also a high percentage of dropouts due to worsened glycaemic control.

Impacto de faster aspart sobre el control glucémico en niños y adolescentes con diabetes tipo 1 en tratamiento con un sistema integrado / The impact of «faster aspart» on blood glucose control in children and adolescents with type 1 diabetes treated using a sensor-augmented insulin pump

Introducción y objetivos: El control glucémico postprandial es fundamental para conseguir los objetivos metabólicos en pacientes con diabetes mellitus tipo 1 (DM1). La nueva insulina faster aspart presenta un perfil farmacológico caracterizado por una absorción e inicio de acción más rápidos, mayor disponibilidad precoz y menor incremento de la glucosa postprandial. El objetivo principal del estudio fue analizar su eficacia en pacientes con DM1 tratados con un sistema integrado.Pacientes y métodos: Estudio analítico, longitudinal, prospectivo y multicéntrico, evaluando el empleo de faster aspart durante tres meses en pacientes en edad pediátrica con DM1 con sistema integrado MiniMed640G® tratados previamente con insulina aspart. Al inicio y final del estudio se analizaron para posterior comparación: glucosa media, porcentajes de tiempo en objetivo, tiempo en hipoglucemia e hiperglucemia, área bajo la curva (AUC) < 70 y > 180 mg/dL, glucosa media pre y postprandial en comidas principales, necesidades diarias de insulina, porcentaje basal/bolo y HbA1c. Se registraron complicaciones agudas y eventos adversos, y se evaluó grado de satisfacción mediante encuesta.Resultados: Se incluyeron 31 pacientes de 13,49 ± 2,42 años de edad con DM1 de 7,0 ± 3,67 años de evolución. Faster aspart se asoció con menor porcentaje de tiempo en hiperglucemia > 180 mg/dL (25,8 ± 11,3 vs. 22,4 ± 9,5; p = 0,011) y > 250 mg/dL (5,2 ± 4,9 vs. 4,0 ± 3,6; p = 0,04) y AUC > 180 mg/dL (10,8 ± 6,5 vs. 9,3 ± 6,1; p = 0,03), incrementándose el tiempo en objetivo (71,4 ± 10,0 vs. 74,3 ± 9,2; p = 0,03) sin aumentar hipoglucemias. Las necesidades de insulina, porcentajes basal/bolo y HbA1c no se modificaron significativamente. Faster aspart fue bien tolerada y valorada por los participantes.Conclusiones: Faster aspart consigue un mejor control glucémico, aumentando el tiempo de glucosa en objetivo en niños y adolescentes con DM1 en tratamiento con un sistema integrado.

Background and aims: Post-prandial glucose control is essential to achieve metabolic goals in patients with type 1 diabetes mellitus (T1DM). The new «faster aspart» insulin has a pharmacological profile noted for its faster absorption and onset of action, and increased early availability, resulting in improved blood glucose control after meals. The main objective of the study was to analyse the efficacy of «faster aspart» vs. «insulin aspart» in children and adolescents with DM1 on sensor-augmented pump treatment.Patients and methods: Multicentre, longitudinal and prospective analytical trial evaluating the use of faster aspart insulin for three months in children with T1DM with MiniMed640G® sensor-augmented pumps previously treated with aspart insulin. At the beginning and end of the study the following variables were analysed for subsequent comparison: mean sensor glucose, percentage of time in range, hypoglycaemia and hyperglycaemia, area under the curve (AUC) < 70 and > 180 mg/dL, mean sensor glucose pre and postprandial in main meals, daily insulin requirements, basal/bolus percentage, and HbA1c. Acute complications, adverse events and satisfaction survey were assessed.Results: The study included 31 patients with a mean of 13.49 ± 2.42 years of age and with T1DM of 7.0 ± 3.67 years of onset. The use of faster aspart was associated with lower time in hyperglycaemia > 180 mg/dL (25.8 ± 11.3 vs. 22.4 ± 9.5; p = 0.011) and > 250 mg/dL (5.2 ± 4.9 vs. 4.0 ± 3.6; p = 0.04), lower AUC > 180 mg/dL (10.8 ± 6.5 vs. 9.3 ± 6.1; p = 0.03), and increased time in range (71.4 ± 10.0 vs. 74.3 ± 9.2; p = 0.03). No significant changes in hypoglycaemia, HbA1c, insulin requirements, and basal/bolus percentages were detected. Faster aspart was safe and well-evaluated by patients and caregivers.Conclusions: Faster aspart achieves better glycaemic control by increasing glucose time in range in children and adolescents with T1DM on treatment with sensor-augmented pumps.
