Jardiance (Empagliflozin) in Chronic Kidney Disease: Clinical Considerations
For patients with chronic kidney disease, empagliflozin is strongly recommended to reduce CKD progression and cardiovascular events in patients with an eGFR ≥20 mL/min/1.73 m² regardless of albuminuria status. 1, 2
Efficacy in CKD
Empagliflozin provides significant benefits for patients with CKD:
- Reduces risk of kidney disease progression by 28% regardless of diabetes status 2
- Slows the rate of eGFR decline by 50% after initial hemodynamic dip 3
- Decreases risk of hospitalization from any cause by 14% 2
- Benefits extend across all CKD etiologies, including diabetic and non-diabetic kidney disease 4
Dosing Guidelines
- Initiation threshold: Can be started in patients with eGFR ≥20 mL/min/1.73 m² 1, 5
- Continuation: Can be continued even if eGFR falls below initiation threshold until dialysis or transplant 1
- Dosing: 10 mg once daily 2
- Monitoring: Assess renal function before initiation and periodically thereafter 6
Mechanism of Renal Protection
Empagliflozin provides renoprotection through multiple mechanisms:
- Reduces intraglomerular pressure by affecting tubuloglomerular feedback 1
- Decreases renal cortical hypoxia by reducing glucose reabsorption burden 1
- Improves structure and function of kidneys damaged by diabetes 1
- Reduces albuminuria and oxidative stress in the kidney 5
Safety Considerations
Volume Status
- May cause intravascular volume contraction 6
- Consider patient's volume status, especially when used with diuretics 1
- Monitor for signs of hypovolemia, particularly during initiation 1
Acute Kidney Injury Risk
- Temporarily discontinue during periods of reduced oral intake or fluid losses 6
- Use caution in patients with risk factors for acute kidney injury 6
Metabolic Considerations
- Risk of euglycemic ketoacidosis, especially in insulin-dependent patients 6
- Consider pausing during acute illness or stressors 1
- Maintain at least low-dose insulin in insulin-requiring individuals 1
Infections
- Increased risk of genital mycotic infections (6% vs 1% with placebo) 1
- Monitor for urinary tract infections, including urosepsis and pyelonephritis 6
Special Populations
Diabetic CKD
- Empagliflozin reduces cardiovascular events and slows CKD progression in diabetic patients 1
- Benefits are independent of glucose-lowering effects 1
Non-diabetic CKD
- Recent evidence from EMPA-KIDNEY trial shows similar benefits in non-diabetic CKD patients 2, 4
- Effective across various etiologies of CKD, including glomerular disease and hypertensive nephropathy 4
Low Albuminuria
- Benefits extend to patients with minimal albuminuria 3
- Relative reduction in chronic eGFR slope was actually greater (86%) in patients with uACR <30 mg/g 3
Practical Implementation
- Before starting: Assess volume status, renal function, and risk factors for adverse effects
- Patient education: Explain potential side effects, especially genital infections and signs of volume depletion
- Sick day protocol: Advise temporary discontinuation during acute illness or 3-4 days before elective procedures 1
- Monitoring: Check renal function at baseline, after 2-4 weeks, and then every 3-6 months 5
Empagliflozin represents a significant advance in CKD management, with benefits extending beyond glycemic control to include direct kidney and cardiovascular protection across a wide spectrum of kidney function and disease etiologies.
