Summary
Propionibacteria species, a common skin bacteria, can cause serious peritonitis in peritoneal dialysis (PD) patients. This case highlights rare PD-associated peritonitis in a patient with CREST syndrome, breast cancer, and recent catheter surgery.
Area of Science:
- Nephrology
- Infectious Diseases
- Microbiology
Background:
- Peritonitis is a serious complication in peritoneal dialysis (PD) patients.
- Unusual causative agents of PD-associated peritonitis are increasingly reported.
- Propionibacteria species, a normal skin flora, can cause severe infections in at-risk individuals.
Observation:
- A 51-year-old female PD patient presented with peritonitis.
- The patient had risk factors including CREST syndrome, breast malignancy, and recent catheter surgery.
- Propionibacteria species was identified as the causative agent of peritonitis.
Findings:
- This case represents the first reported instance of PD-associated peritonitis caused by Propionibacteria species.
- The patient's specific risk factors likely contributed to the development of this rare infection.
Implications:
- This case expands the understanding of etiological agents responsible for PD-associated peritonitis.
- Clinicians should consider Propionibacteria species in the differential diagnosis of peritonitis in PD patients, especially those with similar risk factors.
- Further research may be warranted to elucidate the pathogenesis and optimal management of Propionibacteria-induced peritonitis in PD.
