Pharmacotherapy of type 1 diabetes - part 1: yesterday.

Abstract

Introduction: Type 1 diabetes is a unique autoimmune attack on the β cell of the pancreatic islet resulting in progressive destruction of these cells and as a result the ability of the body to maintain insulin production. The consequences of insulin deficiency are very severe, and the disease was fatal prior to the ability to extract insulin from animal pancreas in 1921. We review progress in the treatment of childhood type 1 diabetes over the past 100 years.

Areas covered: We used PubMed and standard search engines to search for the evolution of diagnosis and treatment of type 1 diabetes.

Expert opinion: Insulin replacement proved lifesaving for children afflicted with type 1 diabetes. However, it was observed that these children suffered from microvascular and large vessel disease. The Diabetes Control and Complications Trial (DCCT) with its extension Epidemiology of Diabetes Interventions and Complications Trial (EDIC) proved that control of blood glucose as close to normal as possible could prevent these diabetes-related conditions. Many formuations of insulin with varying onset and duration of action have been developed; yet normalization of glucose levels is difficult due to hypoglycemic events. There is continued progress toward that goal.
