Retrospective analysis of effects of sodium-glucose co-transporter 2 inhibitor in Japanese type 2 diabetes mellitus patients with chronic kidney disease
Abstract
Aim: The aim of this study was to assess the renal effects of the glucose-lowering SGLT2 inhibitors in Japanese type 2 diabetes mellitus patients with chronic kidney disease. Methods: The Kanagawa Physicians Association maintains a registry of patients who visit their 31 clinics. Clinical data of type 2 diabetes mellitus patients with chronic kidney disease, who were prescribed SGLT2 inhibitors in addition to other treatments, were collected and analysed. Results: SGLT2i was associated with a fall in HbA1c from 64.1\u2009±\u200916.7 mmol/mol (8.0\u2009±\u20091.5%) to 56.5\u2009±\u200912.9 mmol/mol (7.3\u2009±\u20091.2%) (p\u2009<\u20090.01) in 869 analysed cases, a decrease in urine albumin-creatinine ratio from a median of 47.1 to 41.1\u2009mg/gCr, and decrease in estimated glomerular filtration rate from 77.7\u2009±\u200923.9 to 75.0\u2009±\u200923.9\u2009mL/min/1.73\u2009m2 (p\u2009<\u20090.01). The effect on albumin-creatinine ratio was independent of age or stage of estimated glomerular filtration; however, there was a significant negative correlation between albumin-creatinine ratio at the initiation of SGLT2 inhibitor and change in ACR. Multiple linear regression analysis identified use of empagliflozin, β-blockers, and sulphonylureas, Δsystolic blood pressure at office, serum Cr and albumin-creatinine ratio value at initiation of SGLT2 inhibitor as independent and significant determinants of change in ACR. Conclusions: This study confirmed that the beneficial renal effects of SGLT2 inhibitor in Japanese type 2 diabetes mellitus patients with chronic kidney disease, similar to those reported in large-scale clinical trials conducted in Western countries.
