Substitution of Sulfonylureas With New Generation of Hypoglycemic Drugs for the Treatment of Type 2 Diabetes Mellitus

This is a multicentric, prospective, parallel groups study. Patient recruitment will be carried out at the U.O. Departmental Endocrinology and Diabetology ASST FBF Sacco, Fatebenefratelli and Ophthalmic Hospital, and at the SSD of Endocrine Diseases and Diabetology ASST FBF Sacco, L. Sacco Hospital. At the screening visit, patients being treated with sulfonylureas / glinids will be shifted, depending on the subject\'s biochemical and phenotypic characteristics, based on current prescribing criteria and diabetes complications, to one of 4 different types of treatment: 1. GROUP 1: SGLT2 inhibitors +/- Metformin 2. GROUP 2: DPP4 inhibitors +/- Metformin 3. GROUP 3: GLP1-RA + Long-acting insulin +/- Metformin 4. GROUP 4: SGLT2 inhibitors + DPP4 inhibitors +/- Metformin At the screening visit the clinician will evaluate which new treatment to assign to the patient, based on the subject\'s biochemical and phenotypic characteristics, current prescribing criteria and existing complications (Algorithm for the treatment of diabetes mellitus, SID-AMD Care Standard 2018)
