The tunnel infection in PD: Up in the air.

Catheter-related tunnel infection may lead to peritonitis and discontinuation of performing high-quality peritoneal dialysis (PD). Tunnel infection is commonly caused by Staphylococcus aureus. Gas-forming bacterial infection is rare in patients with PD and even exceedingly rare when such a infection spreads along the PD catheter tract. The first case of emphysematous PD catheter infection is presented here.
