Achromobacter xylosoxidans infection is mostly reported in immunocompromised patients. Until now, it is still rarely reported in patients undergoing peritoneal dialysis.

Patient concerns:

This is the 1st case of A xylosoxidans infection due to tunnel infection of a Tenckhoff catheter.


The diagnosis was confirmed by the report of culture.


Risk factors for this infection in peritoneal dialysis include uremia with an immunocompromised state, contamination due to inexperienced skills, and aqueous environment of the dialysate.


We believe that finding the source of A xylosoxidans contamination is the most important aspect of the overall treatment of the infection.


Environmental investigation of suspected source contamination is warranted in those with A xylosoxidans infection. Once the diagnosis is made, removal of the Tenckhoff catheter should not be delayed.
