A70-years of age, male patient with underlying type 2 diabetes mellitus, hypertension, dyslipidemia and ischemic heart disease had undergone continuous ambulatory peritoneal dialysis (CAPD) for 3 years without any episodes of peritonitis.
He was diagnosed with necrotizing fasciitis and later developed peritonitis after receiving a laceration from an aquatic injury
suffered during the flood disaster of 2011. The blood culture, necrotic tissue and the clear dialysate collected upon admission
had shown Aeromonas sobria. The route of peritonitis may be from the hematogenous spread of A. sobria resulting in
necrotizing fasciitis. A. sobria should be considered as the pathogen of peritonitis in PD patients who have history of wounds from contaminated water. We suggest that the PD patients who present with septicemia and did not meet the criteria for peritonitis, the initial dialysate effluent should be sent for culture. The benefit of this is to allow early recognition and treatment of peritonitis.
