Abstract

In 1982, aminoglycosides still are widely prescribed and considered indispensable for the treatment of severe gram-negative infections. All the aminoglycosides are nephrotoxic, but both experimental works and clinical investigations indicate that they do not all have the same nephrotoxic potential. Within the renal tubular cell in several animal species and in man, the initial and the most extensive changes are those that occur in the lysosomes. We compared the effects of gentamicin, tobramycin, netilmicin and, amikacin on (a) lysosomal structural latency, (b) the activity of several enzymes, either lysosomal or those contained in the proximal tubular cell brush border, and (c) the accumulation of myeloid bodies in the lysosomes. From our results, it appears that gentamicin is the aminoglycoside that induces the greatest number of lysosomal changes whereas amikacin induces the least, with the effects of netilmicin and tobramycin quite close to those of amikacin. Other works comparing the nephrotoxicity of aminoglycosides reveal the same high nephrotoxic potential of gentamicin.
