Summary
Purple Urine Bag Syndrome (PUBS) is rare. This case highlights Citrobacter koseri as a potential cause, even without typical Proteus species involvement, in elderly patients with urinary catheters.
Area of Science:
- Urology
- Infectious Diseases
- Medical Microbiology
Background:
- Purple Urine Bag Syndrome (PUBS) is a rare phenomenon characterized by purple discoloration of the urine collection system.
- It is most commonly associated with indwelling urinary catheters and alkaline urine pH.
- The exact microbial causes and contributing factors are not fully elucidated.
Observation:
- A case of PUBS was observed in an 85-year-old woman with a permanent indwelling urinary catheter.
- Purple discoloration of the urine bag occurred four times over one year, independent of urine color changes.
- Episodes coincided with Gram-negative lower urinary tract infections.
Findings:
- The identified pathogens during PUBS episodes were Providencia stuartii and Citrobacter koseri.
- Citrobacter koseri, implicated in this case, has not been previously reported in association with PUBS.
- Proteus mirabilis urinary infection was present in the patient without causing PUBS, challenging previous associations.
Implications:
- This case expands the known microbial spectrum associated with PUBS, including Citrobacter koseri.
- It suggests that the presence of Proteus species may not be a prerequisite for PUBS development.
- Understanding diverse microbial triggers is crucial for managing PUBS in catheterized patients.
