- Pillar 1 (ACE/ARB)ïŒlisinopril/ramipril/perindopril/losartan/valsartan/candesartan max tolerated; acute Cr â 30% OK; monitor K; avoid combo
- Pillar 2 (SGLT2i)ïŒdapagliflozin 10 mg, empagliflozin 10 mg, canagliflozin 100 mg; eGFR ⥠20-25 cutoff; continue to dialysis
- Pillar 3 (Finerenone)ïŒ10 mg â 20 mg daily; eGFR ⥠25, K †4.8 at start; monitor K
- Pillar 4 (GLP-1 RA)ïŒsemaglutide 1 mg/week (FLOW), dulaglutide, liraglutide; tirzepatide (GIP+GLP-1) emerging
- anemiaïŒiron (oral or IV) â ESAs (epoetin, darbepoetin target Hgb 10-11.5) â HIF-PHIs (roxadustat, vadadustat, daprodustat) oral alternative
- CKD-MBDïŒnon-Ca phosphate binders (sevelamer, lanthanum, ferric citrate, sucroferric oxyhydroxide) + active vit D (calcitriol, paricalcitol) + calcimimetics (cinacalcet oral, etelcalcetide parenteral) + parathyroidectomy refractory
- hyperkalemia chronicïŒpatiromer (Veltassa) + sodium zirconium cyclosilicate (SZC, Lokelma)
- acidosisïŒsodium bicarbonate target HCO3 22-26
- emergingïŒsparsentan (atrasentan ETA + ARB) for FSGS/IgA, iptacopan (factor B inhibitor) for C3G/IgA, inaxaplin (APOL1)

- 4 pillars CKD treatment paradigmïŒACE/ARB + SGLT2i + finerenone + GLP-1 RA â ä»»äžæçŒºéœ suboptimal
- SGLT2i äžå€§ CKD trialsïŒCREDENCE (canagliflozin DKD) + DAPA-CKD (dapagliflozin CKD ± DM) + EMPA-KIDNEY (empagliflozin) â éœ â CKD progression + CV events
- finerenone (FIDELIO-DKD + FIGARO-DKD) is non-steroidal selective MRA â less hyperkalemia + less anti-androgen than spironolactone
- FLOW (2024)ïŒsemaglutide in T2DM + CKD â 24% â renal composite endpoint â adds GLP-1 RA to CKD armamentarium
- HIF-PHIs (FDA 2023)ïŒroxadustat (Evrenzo), vadadustat (Vafseo), daprodustat (Jesduvroq) â oral alternative to injectable ESAs; â EPO + â hepcidin
- chronic hyperkalemia in CKDïŒpatiromer + sodium zirconium cyclosilicate (SZC) â newer K binders better tolerated than Kayexalate; allow continuation of ACE/ARB/MRA
- CKD-MBD phosphate binder evolutionïŒnon-Ca-based (sevelamer, lanthanum, ferric citrate, sucroferric oxyhydroxide) preferred to avoid Ca load + vascular calcification
- emerging therapies for specific GNïŒsparsentan (DUPLEX FSGS, PROTECT IgA) + iptacopan (APPLAUSE-IgAN) + inaxaplin (APOL1 nephropathy, AMPLITUDE trial)
- bardoxolone methyl withdrawnïŒBEACON trial 顯瀺 â CV mortality despite eGFR improvement â important to remember (äžèŠåè)
- statin in CKDïŒSHARP trial (simvastatin + ezetimibe) â CV events; primary prevention if eGFR < 60 + albuminuria; benefit less clear in dialysis (4D, AURORA, SHARP analyses)
