title: [Is it possible to reduce the incidence of aminoglycoside-induced nephrotoxicity?].
abstract: The incidence of nephrotoxicity due to aminoglycosides should be sharply reduced. The indications for prescribing these antibiotics should be limited to infectious disorders induced by aerobic Gram-negative bacteria and by some Gram-positive bacteria requiring treatment in specialized hospital units using an association of aminoglycosides and another antibiotic. Daily doses should not exceed those indicated by the manufacturer, and the length of treatment should be as short as possible, with a relay to other antibiotics that are not or are less nephrotoxic. The possibilities for reducing the incidence of nephrotoxicity are few. It is not possible to prevent the antibiotic from entering the renal tubular cell or from producing deleterious effects therein. However, by using short-term intravenous infusion as the administration route, prolonged contact between the antibiotic and its receptors on the brush borders of the proximal tubular cells can be avoided, particularly since the process of cellular absorption is saturable. Essentially, doses should be adapted according to the age and the glomerular filtration of the patient, since renal function usually decreases with age. Volemic and hydroelectrolytic disorders favour nephrotoxicity and should be corrected. Associations with other nephrotoxic drugs should either be avoided or used with increased caution. The same is true in special situations such as endotoxaemia, severe renal parenchymatous infections and cholestasis. In any case, given the well-known insidious onset of nephropathy, aminoglycoside treatment always requires laboratory follow-up consisting of repeated testing of creatinemia during the two weeks of treatment.
