Simultaneous removal and replacement of the peritoneal catheter in CAPD patient with refractory peritonitis sustained by P. aeruginosa: A case-report

Pseudomonas peritonitis is often severe and associated with less than 50% complete cure rate, often requiring catheter removal, and transfer to HD. International guidelines recommend that peritoneal catheter should be removed if peritoneal dialysis (PD) effluent does not clear after 5 days of appropriate antibiotic therapy defining the episode as refractory peritonitis. To avoid the shift to hemodialysis (HD), the simultaneous removal and replacement of the peritoneal catheter (SCR) has been employed to treat recurrent peritonitis or tunnel infections associated with peritonitis, obtaining satisfactory outcomes. However, the use of SCR is still controversial in refractory episodes. At present there is growing evidence that refractory peritonitis can be sustained by bacterial adherence along the intraperitoneal portion of the catheter, especially when Pseudomonas species are involved. We describe a case of refractory peritonitis sustained by P. aeruginosa that after a partial response to antibiotics has been successfully treated by SCR.
