FC 116: SGLT2 Inhibitors in Kidney Transplantation: A Multicenter Study

Abstract

Abstract BACKGROUND AND AIMS SGLT2 inhibitors (SGLT2i) are the first-line therapy in patients with type 2 diabetes mellitus (DM2) and CKD, together with metformin according to most recent published guidelines. They are related to better renal and cardiovascular outcomes. SGLT2i could be potentially benefitial in terms of renal function preservation and cardiovascular outcomes in kidney transplantion (KT). Despite published data about SGLT2i in KT patients with DM2 or new-onset diabetes after transplantation are limited, their use seems to be common in everyday clinical practice. Our aim is to investigate if SGLT2i are safe and well tolerated in a cohort of KT recipients, as well as to analyze clinical and laboratory data at 6 months after SGLT2i initiation. METHOD Multicentre observational study in KT recipients with diabetes under SGLT2i treatment. RESULTS A total of 323 patients were included, and 284 completed a 6-month follow-up. Mean age was 61.2 ± 10.3 years old, 74.4% were men and 41% presented DM2. Previous antidiabetic therapies: insulin (48.1%), DPP4 inhibitors (36.1%) and metformin (33.1%). Empagliflozine was started in 55.8%, dapagliflozine in 23.2% and canagliflozin in 20.6%. After SGLT2i initiation, body weight reduction, an improvement in blood pressure and glycaemic control, higher haemoglobin levels and a decrease in cholesterol levels were observed. Also, a mild decrease in eGFR was detected while albuminuria was lower. These differences were statistically significant (Table 1). In 34 patients (10.5%), SGLT2i was stopped: 2.78% presented urinary tract infection (UTI), 1.5% balanitis and 1.2% important eGFR decreasing slope. During the study period, six patients presented a graft loss (one related to SLGT2) and six patients died (deaths not related to SGLT2i). CONCLUSION SGLT2i have a safe security profile in KT, and are related to a better glycaemic and blood pressure control, as well as to a decrease in albuminuria, and to an improvement in cardiovascular risk factors. Thus, SGLT2i should be prescribed in KT recipients with DM2 or NODAT with adequate eGFR. UTI surveillance is essential in these patients.
