Objective: Intensive lowering of low-density lipoprotein cholesterol (LDL-C) with statins reduces cardiovascular risk but can cause liver-, muscle-, and possibly renal-related adverse events (AEs). We assessed the effects of rosuvastatin on the risk of developing renal impairment or renal failure among participants in the rosuvastatin clinical development program.
Methods: The analysis was based on AE data reported by investigators from 36 studies that included 40,600 participants who did not have advanced, pre-existing renal disease. Rates of renal AEs were determined based on time to first occurrence of renal impairment or renal failure.
Results: Renal impairment or renal failure was reported in 536 study participants during 72,488 patient-years of follow-up. Renal event rates were higher in patients with history of heart failure (n = 5011), hypertension (n = 21,864), diabetes (n = 5165), or estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m(2) (n = 9507) at baseline but did not differ with rosuvastatin compared with placebo or with rosuvastatin 40 mg compared with rosuvastatin 10mg. Relative risk (RR) estimates obtained from pooled analysis of placebo-controlled trials were RR: 1.03 (95% CI: 0.86-1.23, p = 0.777) for any reported renal impairment or renal failure event, RR: 1.02 (95% CI: 0.76-1.37, p = 0.894) for serious renal AEs, and RR: 0.70 (95% CI: 0.36-1.35, p = 0.282) for renal AEs leading to death.
Conclusion: These findings suggest that intensive LDL-C-lowering treatment with rosuvastatin does not affect the risk of developing renal insufficiency or renal failure in patients who do not have advanced, pre-existing renal disease.
