Marked Non-Infectious Elevation of Procalcitonin in a Hemodialysis Patient with Bladder Cancer: A Case Report

Background: Here, we present a rare case of a sustained hemodialysis patient with bladder cancer who had the marked elevation of procalcitonin (PCT) in the absence of evidence for infection. Case Presentation: A patient had significantly elevated PCT but without clinical manifestations of infection. Through evidence-based investigation and collaboration with physicians, clinical pharmacists successfully ruled out infection. Consequently, antibiotics were discontinued, and the patient improved and was discharged from the hospital. Conclusion: The aim is to remind clinical pharmacists and clinicians to conduct comprehensive examination and judgment when encountering similar cases to reduce the occurrence of misdiagnosis in clinical practice.
