Background:
Peritonitis is a frequent complication of PD that can lead to technique discontinuation and increase morbidity and mortality. It is caused mainly by gram-positive bacteria (up to 70%); however, gram-negative organisms usually have relatively poor outcomes. Among gram-negative bacteria, Acinetobacter is rare, especially Acinetobacter ursingii.
Case Report:
We report the third case of PD peritonitis caused by Acinetobacter ursingii, treated with directed intraperitoneal antibiotics with good clinical response and favorable outcome.
Conclusion:
Although Acinetobacter ursingii is rare, it is potentially harmful because of its challenging identification and antibiotic resistance with therapeutic consequences, requiring at least two antibiotics and careful follow up. Keeping in mind that it is ubiquitous, careful technique, training/retraining seems highly recommended.
Insights
Peritonitis in peritoneal dialysis (PD) is serious, often caused by gram-negative bacteria. This case highlights Acinetobacter ursingii peritonitis, a rare but challenging infection requiring specific antibiotic treatment for a favorable outcome.
Area of Science:
- Nephrology
- Infectious Diseases
- Microbiology
Background:
- Peritonitis is a significant complication of peritoneal dialysis (PD), increasing morbidity and mortality.
- Gram-negative bacteria in PD peritonitis are associated with poorer outcomes compared to gram-positive organisms.
- Acinetobacter species, particularly Acinetobacter ursingii, are rare causes of PD peritonitis.
