Patients with type 2 diabetes (T2D) are more prevalent with aging-related comorbidities and frailty, which leads to a shorter life expectancy than non-diabetic individuals and that this excess mortality is largely attributable to cardiovascular causes. Therefore, since diabetes accelerates cellular senescence, attenuating aging process in patients with T2D is expected to reduce progression of comorbidities and eventually increase lifespan. According to previous studies, sodium-glucose cotransporter 2 (SGLT2) inhibitors have shown increased ketone bodies not only in blood but in various tissues including liver, kidney and colon, which could lead to beneficial effects in metabolic diseases. Especially, β-hydroxybutyrate (βHB) inhibits oxidative stress and reduces insulin resistance, which has a positive effect on preventing cardio-renal-metabolic diseases and aging process in patients with T2D. In this context, SGLT2 inhibitor can be a promising option to alleviate senescence process in patients with T2D. However, despite the accumulating evidence that support anti-senescent effect of SGLT2 inhibitor in preclinical models, no clinical study has investigated association between SGLT2 inhibitor use and senescence patients with T2D. Thus, the objective of this study is to determine whether the use of SGLT2 inhibitor is associated with anti-senescent effect in patients with T2D, which may expand the indications of SGLT2 inhibitor other than glycemic control.
