ABSTRACT Aims/Introduction Few studies have assessed whether dynamic kidney function prior to sodium–glucose cotransporter‐2 inhibitor (SGLT2i) initiation influenced subsequent renal outcomes. Thus, the study aimed to investigate whether combining estimated glomerular filtration rate (eGFR) slope and urinary albumin/creatinine ratio (UACR) change prior to using SGLT2i contributes to subsequent kidney outcomes. Materials and Methods This retrospective cohort study utilized data from the Kaohsiung Medical University Hospital Research Database (KMUHRD) in Taiwan. We identified 975 SGLT2i new users with type 2 diabetes from 2016 to 2020, who had an eGFR >60 mL/min/1.73 m 2 and UACR 30% eGFR decline with a drop in eGFR categories and a >43% UACR increase with progression in UACR categories. Results After SGLT2i treatment, compared with the non‐progressive renal function group, the glomerular injury group significantly lowered the risk of eGFR decline (adjusted hazard ratio 95% CI 0.384 0.199, 0.740) and UACR progression (adjusted hazard ratio 95% CI 0.514 0.313, 0.846). In addition, for those with a major eGFR decline before starting SGLT2i, significant improvements in the eGFR slope ( P < 0.05) were observed after the treatment, irrespective of UACR increase. Conclusions Early initiation of SGLT2i among type 2 diabetes patients with low‐risk renal disease progression and glomerular injury renal status may prevent them from progressing into chronic kidney disease.
