Abstract：
:Aminoglycoside antibiotics play an integral role in antimicrobial chemotherapy. Unfortunately, these drugs are known to cause nephrotoxicity in man and experimental animals. In fact, the incidence of renal dysfunction during the course of clinical treatment with aminoglycoside antibiotics is approximately 10%. Over the past two decades the elucidation of the pathogenesis of aminoglycoside-induced nephrotoxicity has been the subject of numerous investigations. This review describes the recent theories postulated to play a role in the pathogenesis of antibiotic-induced renal damage. In particular, the importance of amino-glycoside levels in the renal cortex or at the membrane binding site is examined in detail. The relevance of antibiotic tissue levels is reflected in the ability of other drugs to modify nephrotoxicity through an alteration in renal aminoglycoside content. The role of factors including age and diet in drug-induced nephrotoxicity is described. In clinical practice, aminoglycoside antibiotics may often be with other agents. The influence of aminoglycoside interaction with other drugs including vancomycin, cephalosporins and cytotoxic drugs is examined in the light of reports that nephrotoxicity is potentiated in these situations. In addition, this review focuses on the role of infection (pyelonephritis and septicemia) and bacterial endotoxin as pathogenic factors involved in aminoglycoside nephrotoxicity. Both the direct influence of endotoxin and the indirect effects of vasoactive mediators and inflammatory processes will be discussed. A multiplicity of factors is involved in the pathogenesis of aminoglycoside-induced nephrotoxicity and these are further amplified in the presence of infection.
