[Acute renal insufficiency after the administration of tetracycline and gentamycin]

The clinical course of eight case reports of patients with acute renal failure after administration of nephrotoxic antibiotics--specially of tetracycline and gentamycin--is demonstrated. All patients were suffering on preexisting nephropathy, many of them in stage of chronic renal failure according to various etiopathogenesis. As concomitant factor inducing acute renal failure together with antibiotics are: elderly, hepatopathy, surgical interventions, administration of other nephrotoxic drugs. In 6 patients, where acute renal failure induced by nonreducted doses of antibiotics appeared, the treatment was successful, in five cases due to short term haemodialysis, once conservatively with diuretics and volume diuresis. Two patients died before the therapeutic measures and dialysis could be performed. Algorithms in diagnosis and treatment of chronic renal failure--patients where antibiotic treatment is necessary are discussed.
