Abstract

A man in his early 50s with no significant prior renal history was admitted with acute kidney injury and sepsis secondary to right lower limb cellulitis, requiring prompt multidisciplinary management and further evaluation of the underlying etiology. Initial treatment included hemodialysis, following which the patient developed polyarticular septic arthritis (PASA), a rare condition. Examination revealed significant swelling and tenderness in multiple joints, and microbiological analysis confirmed a Staphylococcus aureus infection. Hemodialysis precipitated the bloodstream infection, as blood cultures were negative before hemodialysis but positive for Staphylococcus aureus post-dialysis. The patient underwent multiple joint washouts and was treated with intravenous vancomycin and linezolid. The patient's renal function normalized after treatment, and his symptoms resolved without recurrence. This case highlights the potential for PASA in an immunocompetent individual after a single hemodialysis session, emphasizing the role of catheter-related bloodstream infection (CRBSI) in its pathogenesis and underscoring the importance of timely diagnosis and treatment to prevent severe outcomes. Such presentations underscore the importance of heightened clinical vigilance, as delayed recognition can result in significant morbidity.
