Afferent Efferent Afferent Efferent Pharmacological Haemodynamic effects and clinical actions: implications: SGLT2 inhibition A • Decreased intraglomerular pressure due to increased afferent resistance in T1D-H patients Afferent constriction • Decreased hyperfiltration • Decreased intraglomerular pressure due to B decreased efferent resistance RAAS blockade • Decreased hyperfiltration Efferent dilation • Proven renal protection in clinical trials • Normalisation of intraglomerular pressure due to SGLT2 inhibition and increased afferent and decreased efferent RAAS blockade resistance? C • Potential for additive intraglomerular pressure Afferent constriction and reduction? Efferent dilation • Potential for long-term renal protection? Skrtić //Cherney.

Conclusions and key messages • SGLT2i: intraglomerular hypertension – eGFR dip: occurs in CKD stages 3a, 3b, CKD – eGFR slope, albuminuria, effects in large CV trials – CREDENCE study: stopped early due to efficacy – DAPA-CKD and empagliflozin studies • Effects relatively independent of HbA1c lowering CKD, chronic kidney disease; eGFR, estimated glomerular filtration rate; SGLT2i, sodium – glucose co-transporter 2 inhibitor; TGFB, tubuloglomerular feedback; UACR, urinary albumin:creatinine ratio
