Nephrotoxic acute renal failure due to common drugs.
Antibiotics are the most common drugs implicated in clinical reports of drug-induced nephrotoxicity. The experimental basis for proposed mechanisms of acute renal failure in association with three groups of antibiotics--aminoglycoside, cephalosporin, and amphotericin B--are reviewed in detail. Proposed mechanisms of antibiotic-induced acute renal tubular necrosis involve either altering plasma membrane permeability or interference with cellular energy derived from mitochondria, For either aminoglycoside or cephalosporin antibiotics, cellular accumulation followed by interruption of mitochondrial respiration is the concept that has greatest support, although the possibility of an induced phospholipidosis involving intracellular lysosomes cannot be excluded. Altered renal tubular cell permeability due to the incorporation of amphotericin B into the pore structure of the plasma membrane is consistent with in vivo observation in either clinical or experimental examples of nephrotoxicity with this agent. The metal cis-platinum, used in treatment of neoplastic disease, has a clearly defined incidence of clinical nephrotoxicity with little insight as to cellular mechanisms. A possible mediation involving cis-platinum reducing the protein-bound sulfhydryl group of renal tissue has been proposed. With the ever increasing potency of modern pharmacologic agents come a rising risk of serious toxic side effects.
