How should a PD patient be managed if effluent culture is negative after suspected peritonitis but symptoms persist?

• A. Stop antibiotics
• B. Switch to hemodialysis
• C. Reassess diagnosis, consider repeat culture, continue antimicrobial therapy for the recommended duration, and monitor clinical response
• D. Ignore symptoms

Answer: (C)

A suspected PD-related peritonitis with a negative effluent culture still requires continued treatment based on the clinical picture; culture negativity does not rule out infection. Cultures can be negative for several reasons, such as prior antibiotics, low bacterial load, or growth challenges with unusual organisms. When symptoms persist despite a negative culture, the appropriate approach is to reassess the diagnosis, consider repeating the culture to detect organisms that were not identified initially, continue antimicrobial therapy for the full recommended duration, and monitor the patient’s clinical response. This strategy treats the patient’s ongoing infection risk while you verify the diagnosis and adjust as needed. Stopping antibiotics or ignoring symptoms would risk worsening infection, and switching to hemodialysis is not the immediate, evidence-based step just because the culture is negative. If there’s no improvement after an appropriate course, further evaluation and management decisions, including possible catheter considerations, would be warranted.
