Statins against drug-induced nephrotoxicity

Area of Science:

• Nephrology
• Pharmacology
• Biomedical Science

Background:

• Drug-induced nephrotoxicity (DIN) is a significant cause of hospital-acquired acute kidney injury, leading to substantial morbidity and mortality.
• Despite efforts to mitigate DIN, it remains a clinical concern.
• Statins possess antioxidant, anti-inflammatory, and anti-apoptotic properties, suggesting potential renoprotective effects against DIN.

Purpose of the Study:

• To review existing in vitro and in vivo studies on the renoprotective efficacy of statins against nephrotoxic agents.
• To evaluate the potential of statins in preventing or mitigating drug-induced kidney damage.

Main Methods:

• Comprehensive literature search of Medline, PubMed, Scopus, and Cochrane databases.
• Inclusion of English-language articles examining statins as renoprotective agents against various nephrotoxic drugs.
• Analysis of both in vitro and in vivo study data.

Main Results:

• Chronic statin use may decrease susceptibility to contrast-induced nephropathy (CIN).
• Short-term, high-dose statin administration might reduce CIN incidence in statin-naïve individuals, particularly in low-risk patients with normal or mildly impaired kidney function.
• Animal studies suggest statins may protect against gentamicin-, cisplatin-, and cyclosporine-induced nephrotoxicity, though human data are pending.

Conclusions:

• Statins demonstrate potential as renoprotective agents, particularly against CIN in specific patient populations.
• Further clinical validation is required to confirm the protective effects of statins against other forms of drug-induced nephrotoxicity observed in animal models.
