[Peritoneal dialysis-associated peritonitis caused by Rhizobium species - a case report]

Area of Science:

• Nephrology
• Infectious Diseases
• Microbiology

Background:

• Peritonitis is a significant complication in patients undergoing peritoneal dialysis (PD).
• High rates of morbidity and mortality are associated with PD-related peritonitis.
• Prompt and accurate diagnosis is crucial for effective management.

Observation:

• A case of PD-associated peritonitis caused by the rare pathogen Rhizobium is presented.
• Initial treatment with vancomycin and tobramycin failed, with persistent bacterial growth.
• Antimicrobial susceptibility testing guided a change in therapy.

Findings:

• Intravenous meropenem and intraperitoneal ciprofloxacin were administered based on susceptibility results.
• The patient recovered successfully without the need for PD-catheter removal.
• This demonstrates the efficacy of targeted antimicrobial therapy against unusual pathogens.

Implications:

• Patients on PD are susceptible to infections by uncommon microbial agents.
• Unusual pathogens should be considered in cases of antibiotic treatment failure in PD peritonitis.
• Preserving the PD catheter through effective treatment is a key goal in managing PD-associated infections.
