In recent years, new resources have been appearing in order to improve glycaemic control in patients with type 1 diabetes. These include new insulin analogues, glucose monitoring, smart insulin pens and hybrid close-loop systems.

Finally, in the following years biological drugs such as teplizumab will be incorporated, which will be the first etiological treatment for type 1 diabetes.
