Actinomyces Peritonitis In Setting of Peritoneal Dialysis Catheter

Abstract Background: A patient presents with an exceptionally rare Actinomycesperitoneal dialysis infection, which has only been recorded 4 times prior in literature. Case presentation: A 46-year-old female with end stage kidney disease on peritoneal dialysis presented to the emergency department with shortness of breath. She recently was hospitalized due to her peritoneal dialysis catheter malfunctioning. During the hospitalization Computed Tomography of her abdomen showed a small amount of ascites around the newly placed peritoneal dialysis catheter. The patient was treated with intraperitoneal ceftriaxone for a total of four total weeks of therapy. The patient had good clinical response and repeat cultures and cell count were unremarkable. Conclusions: Intraperitoneal antibiotics may be an effective treatment for peritoneal dialysis catheter peritonitis caused by Actinomyces. If the Actinomycesorganism is susceptible to ceftriaxone, it could be a good option for intraperitoneal dialysis due to its once daily dosing and was successful in this case.
