Empagliflozin in kidney transplant recipients with chronic kidney disease G3a-4 and metabolic syndrome: Five Japanese cases.

BACKGROUND

Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been shown to exert cardiorenal protective effects in diabetic patients and are widely used clinically. In addition, an increasing number of reports now suggest these drugs may even be beneficial in non-diabetic patients. However, SGLT2 inhibitors are rarely prescribed for kidney transplant recipients due to the risk of renal graft damage and urogenital infections.

CASE PRESENTATION

We report the cases of 5 renal transplant recipients with chronic kidney disease G3a-4 and metabolic syndrome who were administered the SGLT2 inhibitor empagliflozin, which yielded beneficial results in 4 cases. With the exception of one patient with an initial estimated glomerular filtration rate (eGFR) of less than 30 ml/min/1.73 m2, administration of empagliflozin elicited beneficial metabolic effects. There were no significant reductions in eGFR before or after empagliflozin administration, and no dehydration or urogenital infections were observed during the treatment course.

CONCLUSION

Empagliflozin showed some positive effects in 4 cases with better renal function than CKD stage 4. Further studies will be required to clarify the efficacy and safety of SGLT2 inhibitors in a larger group of patients with similar medical conditions.
