Advances in newer basal and bolus insulins: impact on type 1 diabetes. Issue 1 (February 2021) - Vliebergh, Joke
Abstract : Purpose of review: Insulin administration is vitally important to maintain a good glycaemic control in people with type 1 diabetes mellitus (T1DM). The purpose of this review is to give a clinically relevant overview of the newer basal and bolus insulin analogues and to highlight their practicalities of use and advantages in specific categories of patients with T1DM. Recent findings: Second-generation rapid-acting insulin analogues (i.e. faster insulin aspart and ultrarapid-acting lispro) have shown to be safe, efficient and superior in controlling postprandial plasma glucose levels without an increase in hypoglycaemia. The newest basal insulin analogues, insulin glargine U300 and degludec, have proven to be efficient in reducing hypoglycaemic events due to a more stable action profile. Summary: The second-generation rapid-acting and basal insulin analogues approach better the desired physiological insulin pattern of the beta cell. Due to a faster absorption, it is possible to inject the prandial insulin analogues more closely or even after meals without compromising postprandial glucose control. Due to more stable release patterns, basal insulins now have more reliable and longer profiles, covering basal insulin demands in a superior way, leading to a better glycaemic control with less hypoglycaemia (especially nocturnal events) and an improved quality of life.
