Renal Abscess and Peritonitis in a Peritoneal Dialysis Patient: A Novel Route of Infection.

We present a peritoneal dialysis (PD) patient who had a renal biopsy performed during an episode of urosepsis and subsequently presented with a renal abscess at the biopsy site along with concurrent peritonitis. Microbiology from the PD effluent and from the renal abscess were both positive for We propose that the PD peritonitis was the result of seeding of the peritoneal cavity with bacteria from the renal abscess. Successful treatment was achieved through drainage of the abscess and intraperitoneal antibiotics.

Case of Mycobacterium mucogenicum in a home hemodialysis patient.

We present a case of a patient on home hemodialysis who developed Mycobacterium mucogenicum bacteremia. While infections with this particular organism are rare, disseminated infections have been reported and have been associated with significant morbidity and mortality. Diagnosis required appropriate cultures, understanding of natural habitat of organism and complete environmental analysis including blood, dialysis sample port, reverse osmosis and incoming water supply cultures.

Antibiotic Prophylaxis in Peritoneal Dialysis Patients.

Peritonitis is an important cause of morbidity, mortality, and technique failure in patients on peritoneal dialysis (PD). The most effective approach to peritonitis is prevention, which includes careful patient training and follow-up. Although peritonitis as a result of contiguous spread of bacteria or fungi during invasive procedures, or as a result of seeding of the peritoneum during bacteremia, is uncommon, the likelihood of such spread is often predictable, and the risk can be mitigated with antibiotic prophylaxis.
