A Rare Cause of Automated Peritoneal Dialysis-Related Peritonitis: Aeromonas caviae

  • 1Division of Nephrology, Department of Internal Medicine, Dong Rae Bong Seng Hospital, Busan, Korea. 59356815@hanmail.net


Peritonitis is a major cause of morbidity in peritoneal dialysis patients; however, Aeromonas caviae rarely causes peritonitis in these patients. We report peritonitis due to A. caviae in a 72-year-old male with end-stage renal failure who had been undergoing automated peritoneal dialysis for 1 year. The white blood cell (WBC) count in the peritoneal fluid was 2,722/mm3 with 85% neutrophils. Gram staining of the peritoneal fluid yielded Gram-negative rods. Empirical antibiotic therapy with ceftriaxone was initiated intraperitoneally. However, drug sensitivity testing revealed that the organism was resistant. On the third hospital day, A. caviae was cultured from the peritoneal effluent, and the antibiotic regimen was switched to ciprofloxacin. The patient recovered rapidly and the WBC count of the peritoneal effluent decreased. He was discharged and the intraperitoneal ciprofloxacin therapy was continued for 14 days. The peritoneal catheter was not removed.
