[Prevention of nephrotoxicity of amphotericin B during the treatment of deep candidiasis].

Previous observations suggest that tubulo-glomerular feedback could be involved in amphotericin B nephrotoxicity. We then investigated the influence of sodium status on the occurrence of renal damage during amphotericin B therapy. A retrospective survey demonstrated that impaired renal function occurred during therapy in 67 per cent of the patients who received amphotericin B alone and in 12 per cent of the patients who received amphotericin B and ticarcillin (parenteral sodium supplement of 100-150 meq per day). Prospective studies were then undertaken both in adults and children. Intravenous sodium supplement was given intravenously as routine prophylaxis with amphotericin B therapy. In all courses amphotericin B was successfully administered without deterioration in renal function. These results support the hypothesis that parenteral sodium supplementation reduces the frequency of developing impaired renal function during amphotericin B therapy.
