Refractory Salmonella enterica Serotype choleraesuis-Related Renal Cyst Infection in a Patient with Autosomal Dominant Polycystic Kidney Disease Undergoing Hemodialysis Treated Successfully with Intracystic Ciprofloxacin Infusion
Objective: To report a potential salvage therapy for refractory renal cyst infection secondary to Salmonellaenterica serotype choleraesuis (S. choleraesuis).Clinical Presentation and Intervention: A 52-year-old male with autosomal dominant polycystic kidney disease undergoing hemodialysis experienced an episode of S. choleraesuis-related gastroenteritis subsequently complicated by bloodstream and refractory renal cyst infection with formation of multiple pyocysts. The patient was treated with intracystic indwelling diluted ciprofloxacin solution. Conclusion: In this patient, intracystic infusion of ciprofloxacin achieved a sufficient antibiotic level in infected renal cysts and hence completely eradicated S. choleraesuis. Therefore, intracystic antiobiotic infusion could be a potential salvage therapy for refractory renal cyst infection.
