From the Guidelines
For patients with chronic kidney disease (CKD) stage 3b, simvastatin is a reasonable choice due to its established benefits in reducing major cardiovascular events, as demonstrated in the Study of Heart and Renal Protection (SHARP) trial 1.
Key Considerations
- The SHARP trial showed a 25% reduction in nonhemorrhagic stroke in the treatment arm, which included simvastatin 20 mg daily plus ezetimibe 10 mg daily 1.
- Simvastatin can be used at standard doses (20-40 mg daily) in CKD stage 3b, with consideration for dose adjustment based on individual patient factors.
- While rosuvastatin may offer superior lipid-lowering efficacy, the choice between simvastatin and rosuvastatin should ultimately consider the patient's cardiovascular risk, comorbidities, concomitant medications, and individual tolerance.
Monitoring and Safety
- Patients should be monitored for muscle symptoms (myalgia, weakness), liver function abnormalities, and potential drug interactions with both medications.
- Regular monitoring of kidney function, lipid levels, and side effects is essential with either medication.
Clinical Guidelines
- The Kidney Disease: Improving Global Outcomes (KDIGO) guideline recommends treating all individuals with CKD who are older than 50 years with statins, regardless of LDL cholesterol level 1.
- The American College of Cardiology/American Heart Association (ACC/AHA) guideline recommends using a risk calculator to determine the need for statin therapy, but notes that individuals with CKD may have a higher risk of cardiovascular events than predicted by the calculator 1.
From the Research
Comparative Efficacy of Simvastatin and Rosuvastatin in CKD Stage 3b
- The available evidence does not provide a direct comparison between Simvastatin and Rosuvastatin in patients with Chronic Kidney Disease (CKD) stage 3b 2, 3, 4, 5, 6.
- However, studies suggest that statins, including Rosuvastatin, may have a beneficial effect on renal function in patients with CKD 5.
- A study found that statin use was associated with a lower risk of CKD progression in patients with CKD stage 3B-5, but not in those with CKD stage 1-3A 5.
- Rosuvastatin has been shown to improve estimated glomerular filtration rate (eGFR) and decrease albuminuria in patients with moderately impaired kidney function 2.
- Another study found that a multidisciplinary approach to CKD care, which may include statin therapy, can slow renal progression in patients with up to stage 3b CKD 4.
- The pharmacokinetic and pharmacodynamic profile of Rosuvastatin in patients with end-stage renal disease on chronic haemodialysis has been studied, but the results may not be directly applicable to patients with CKD stage 3b 6.
Key Findings
- Statins may have a beneficial effect on renal function in patients with CKD, particularly in those with CKD stage 3B-5 5.
- Rosuvastatin may improve eGFR and decrease albuminuria in patients with moderately impaired kidney function 2.
- A multidisciplinary approach to CKD care, which may include statin therapy, can slow renal progression in patients with up to stage 3b CKD 4.
Limitations
- The available evidence does not provide a direct comparison between Simvastatin and Rosuvastatin in patients with CKD stage 3b.
- The studies included in the analysis had different study designs, populations, and outcomes, which may limit the generalizability of the findings.
