Canagliflozin should be prescribed with caution to individuals with type 2 diabetes and high risk of amputation
Around 80% of lower extremity amputations (LEA) in individuals with diabetes are preceded by a diabetic foot ulcer . Diabetic foot ulcers usually occur due to a direct or indirect trauma associated with loss of protective sensation and are frequently accompanied by peripheral artery disease. Several factors increase the risk of LEA in diabetic individuals with or without diabetic foot ulcers, such as male sex, sensory neuropathy, peripheral artery disease, prior history of foot ulcer or amputation, poor glycaemic control, renal dysfunction, non-Asian ethnicity and presence of infection [2, 3, 4, 5, 6, 7, 8]. Recently, the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial, in which individuals were randomised to receive intensive therapy (HbA1c <42 mmol/mol [<6%]) or standard glycaemic control (HbA1c 53–63 mmol/mol [7.0–7.9%]), showed that the intensive regimen resulted in a significant decrease in LEA risk and that mean HbA1cstrongly predicted LEA...
