Introduction: There is no report of efficacy and safety of canagliflozin, a sodium glucose cotransporter 2 (SGLT2) inhibitor in post kidney transplant patients with diabetes.
Materials and methods: A pilot study was undertaken in stable renal transplant recipients with preexisting diabetes or new onset diabetes after transplantation (NODAT) to look at the efficacy of SGLT2 inhibitor, cangliflozin. With the introduction of canagliflozin (100 mg), the dose of insulin and/or other oral hypoglycemic agents was reduced if the blood sugar control improved. The parameters monitored were body weight, blood pressure (BP), serum creatinine, HbA1c, and tacrolimus trough level. Safety was assessed by adverse event (AE) reports. Each patient was followed for a minimum period of 6 months.
Results: The study included 24 (23 males and 1 females) stable kidney transplant patients with diabetes. The mean age of the patients was 53.8 ± 7.12 years. The mean body weight of study subjects was 78.6 ± 12.1 kg before and 76.1 ± 11.2 kg 6 months after starting canagliflozin (P < 0.05). The mean systolic and diastolic BP (mm Hg) was 142 ± 21 and 81 ± 9 before and 134 ± 17 and 79 ± 8, 6 months after starting canagliflozin, respectively (P < 0.05 for systolic BP). There was no significant change in creatinine level (mg/dL). It was 1.1 ± 0.2 before and 1.1 ± 0.3 after starting canagliflozin. The tacrolimus level (ng/mL) was 6.7 ± 3.7 before and 6.1 ± 2, 6 months after starting canagliflozin. The mean HbA1c before was 8.5 ± 1.5%. At 6 months, it was 7.6 ± 1%. Hypoglycemia was not seen. There was no increase in infections.
Conclusion: Canagliflozin provided reductions in body weight, BP, HbA1c, and the requirement of other hypoglycemic agents without any hypoglycemic episodes and without significant AEs.
