Effectiveness of Faster Aspart versus Insulin Aspart in Children with Type 1 Diabetes: A Meta-Analysis.

BACKGROUND: Intensive insulin regimens are recommended to achieve glycemic goals in children and adolescents with type 1 diabetes. Fast-acting insulin aspart (faster aspart) is a new formulation of insulin aspart (IAsp) in which L-arginine and niacinamide are added to assure formulation stability, early absorption, and ultra-fast action. This meta-analysis compares faster aspart with IAsp for blood sugar control in children with type 1 diabetes. This study suggested treating diabetes with insulin, especially in children with type 1 diabetes.

METHODS: PubMed, MEDLINE, Embase, Cochrane Library, Web of Science, and Google Scholar were searched from 2000 to 2023 without language restrictions. Blood glucose monitoring, HbA1c, care model, insulin aspart, IAsp, faster aspart, type 1 diabetes, and pediatrics are Mesh keywords. Cochrane Q statistics and index tested heterogeneity. To account for heterogeneity, Q=145.99 ( P -value < 0.001) and =97.26%, and the random-effect model was used to aggregate primary study results. The meta-analysis of randomized-controlled trials was conducted in accordance with PRISMA standards.

RESULTS: The overall estimate measure i.e. mean difference was found to be 5.44 [0.45, 10.44] and 7.71 [7.16, 8.26] which indicate significant reduction in the HbA1C level in the fast acting insulin aspart group as compared to the IAsp in T1D. However, the mean difference with respect to BMI was found to be -0.06 [-0.60, 0.48] which indicate non-significant reduction.

CONCLUSION: Faster aspart had faster onset and more early exposure than IAsp in children and adolescents with greater and more variable anti-insulin antibody levels than adults did. Hence fast-acting insulin aspart may provide better glucose control than IAsp in T1D.
