Early effects of gentamicin, tobramycin, and amikacin on the human kidney.


The early alterations at the level of the proximal tubule of the human kidney caused by the three most currently used aminoglycosides, gentamicin, tobramycin, and amikacin, were studied. A prospective, randomized, and comparative approach using multidisciplinary methods was used. The patients received either no treatment or one of the three aminoglycosides at a therapeutic dose for 4 days preceding nephrectomy for neoplasia partly involving one kidney. The three aminoglycosides studied induce an early lysosomal phospholipidosis. Gentamicin and tobramycin cannot be distinguished on the basis of drug tissue accumulation, lysosomal overloading, or effect on lysosomal phospholipase A1. Amikacin induces significantly lower lysosomal overloading and no loss of phospholipase A1 activity.
