Periprostetic Joint Infection Caused by : Case Reports of Two Azathioprine and Prednisolone Induced-immunocompromised Patients.

Periprosthetic joint infection (PJI) due to is rare. It frequently occurs patients receiving immunosuppressive medicine. We describe two periprosthetic infection of two immunocompromised patients. Both of patients were receiving azathioprine and prednisolone therapy. First patient presented six years after total hip arthroplasty with a huge abscess on her right thigh that was reached to femoral component through the lytic area of lateral femur. Second patient presented with drainage from his hip and he had undergone two-step revision surgery for PJI 3 months ago. There is no consensus in the treatment of periprosthetic salmonella infections. We prefer two-step revision surgery for these infections as previously described in the literature.
