Brief Summary:
GIOIA represents a multicenter pragmatic prospective cohort study, aimed at evaluating the effects of SGLT2 inhibitors currently marketed (dapagliflozin, canagliflozin, empagliflozin) on markers of vascular, myocardial and renal damage, in patients with type 2 diabetes not well controlled with metformin and/or basal insulin. The changes of the interest outcomes are compared with those obtained with a comparator glucose lowering class (DPP-4inhibitors) over a follow-up of two years.

Condition or disease Intervention/treatment

 Drug: DPP-4i
Sitagliptin or vildagliptin or saxagliptin or linagliptin or alogliptin add on to metformin ± basal insulin

  3. Urinary albumin to creatinine ratio excretion [ Time Frame: 24 months ]
    Development of microalbuminuria in normoalbuminuric patients at baseline or development of macroalbuminuria in patients with microalbuminuria at baseline; regression of microalbuminuria to normoalbuminuria or regression of macroalbuminuria to microalbuminuria


Secondary Outcome Measures :
  1. Weight [ Time Frame: 24 months ]

  3. Waist circumference (WC) [ Time Frame: 24 months ]
    Change in waist circumference in cm from baseline

  4. Blood pressure [ Time Frame: 24 months ]
    Change in systolic and dyastolic blood pressure in mmHg from baseline

  5. estimated Glomerular filtration rate (eGFR) [ Time Frame: 24 months ]
    Change in estimated glomerular filtration rate in mI/min/1.73 mq from baseline


Other Outcome Measures:
  1. HbA1c [ Time Frame: 24 months ]
    Change in HbA1c in % from baseline

  2. Mean amplitude glucose excursions (MAGE) [ Time Frame: 24 months ]
    Change in MAGE in mmol/L from baseline
