Effects of SGLT2 inhibitors (SGLT2i) on renal functions were examined in patients with type 2 diabetes followed by our clinic. Subjects were 395 outpatients treated with SGLT2i (ipragliflozin 135; empagliflozin 101; canagliflozin 83; dapagliflozin 76; age 51.6 ± 11.3 years; duration of diabetes 7.21 ± 6.8 years; BMI 28.6 ± 4.5). Changes in eGFR at 1 year before and 2 years after the administration of SGLT2i versus at baseline were retrospectively analyzed in 2 groups divided by the baseline eGFR; eGFR&lt;90 ml/min/1.73m2 group and eGFR≧90 group. The changes in urinary albumin excretion rate (UAER) and HbA1c levels were also examined. The average values of each four measures in a year were used as the levels for each period. In the eGFR&lt;90 group (n = 179), the annual change in eGFR (ΔGFR) was -2.1 ± 5.5/year before administration of SGLT2i (p &lt;0.001), -1.4 ± 7.5/year after 1 year (p = 0.020) and +0.2 ± 5.9/year between 1 and 2 years (p = 0.704). In the eGFR≧90 group (n = 164), ΔGFR was -1.2 ± 8.0/year before administration of SGLT2i (p = 0.180), -3.2 ± 11.6/year after 1 year (p = 0.001) and -1.2 ± 8.2/year between 1 and 2 years (p = 0.133). In the group with ΔGFR?-5/year before administration of SGLT2i (n = 56), ΔGFR was -9.1 ± 3.5/year before administration (p &lt;0.001), -0.9 ± 8.9/year after 1 year (p = 0.473) and -2.4 ± 10.6/year between 1 and 2 years (p = 0.176). In the group with ΔGFR &gt;-5/year before administration (n = 137), ΔGFR was +1.9 ± 5.3/year before administration (p &lt;0.001), -4.1 ± 9.5/year after 1 year (p &lt;0.001) and +0.6 ± 6.0/year between 1 and 2 years (p = 0.306). UAER changes in total subjects were +41.1 ± 267.5 mg/g creatinine/year before administration of SGLT2i (p = 0.039), -8.8 ± 220.1/year after 1 year (p = 0.474) and +8.0 ± 88.0/year between 1 and 2 years (p = 0.144).
HbA1c levels were 7.27 ± 1.19% and 7.67 ± 1.31 at 1 year before and baseline, respectively, and decreased at 2 years (-0.49 ± 1.16%, p &lt;0.001, n = 145). These observations suggest that SGLT2i may have protective effects on renal functions in the real-world clinical practice.
