This work is aimed at improving the quality of life of older patients affected by type 2 diabetes. The investigators will try to amiliorate the complexity of hypogliceamic treatment in a little group of older patients with type 2 diabetes reducing the number of pills and/or insulin administration using a single daily dose of a fixed combination of insulin degludec and liraglutide. This therapeutic semplification will be done indipendently of pre-existent glicaemic control.

Older patients with type 2 diabetes often have numerous coexisting medical problems for which these subjets prescribed multiple medications. Actually, diabetes, hyertension, cardiovascular diseases (CVDs), neurodegenerative diseases (NDDs), digestive and respiratory disorders are common in aged peolple and tend to coexist. Unfortunally, the complex therapy of these diseases increases the risk of adverse drug events. Furthermore, there is marked heterogeneity in health status and functional capacity in older diabetic subjects, often making prescribing decisions complex and challenging. On the other hand, despite of the use of many medicines, undertreatment is also frequent present in the elderly and the probability of underprescription increased significantly with the number of medicines.Both conditions have a detrimental effect on quality of life (QoL) of elderly subjects increasing the risk of disability and death. Therefore, older people should benefit greatly of a simplification of drug regimens and reduction of pill burdens as well as better explanations of the reason for the prescriptions. The combination of insulin degludec (100 units/mL) and liraglutide (3.6 mg/mL), termed IDegLira, was approved in 2014 for the treatment of type 2 diabetes inadequately controlled with oral glucose-lowering agents alone or in combination with a GLP-1 receptor agonist or basal insulin (European indication). Interestingly, RCTs and real-world evidence provided insights into effectiveness and safety in routine clinical practice. However, beyond its known metabolic efficacy IDegLira has a very small hypoglicaemic rate, with a single daily and flexible administration dose and a very good safety profile that makes it suitable for fragile diabetic old patients.
