Management of Candida peritonitis by prolonged peritoneal lavage containing 5-fluorocytosine

A 55 year old woman on chronic maintenance peritoneal dialysis developed Candida albicans peritonitis. This was successfully treated by continous five day peritoneal lavage containing 5-fluorocytosine. By this technique stable serum levels of the drug (58 mug/ml +/- 3.2 SEM) could be maintained. The peritoneal clearance of 5-fluorocytosine was found to be 7.5 ml/min (for peritoneal dialysis flow rate 1.2 1/hr) and the serum half-life 34 hours. The use of this drug in renal failure and its kinetics are reviewed.
