Infectious spondylodiscitis in patients with central venous catheters for haemodialysis: a retrospective study

Abstract

Aim: To evaluate the prevalence of infectious spondylodiscitis associated with central venous catheters (CVC) for haemodialysis.

Methods: Descriptive and retrospective research. Clinical histories of 830 patients with a CVC for haemodialysis in our unit were reviewed from January 1999 to December 2010. Clinical data associated with spondylodiscitis were collected.

Results: Five out of 830 patients reported infectious spondylodiscitis associated with their CVC for haemodialysis. Of the five cases, the average age was 66 years (range 59-72 years), there were four females and one male. Three had diabetic nephropathy. Site of CVC: four jugular, one femoral. Signs and symptoms: fever and leucocytosis 100%, lumbar pain 85%; positive blood cultures 60%; computed axial tomography and magnetic resonance imaging showing signs suggestive of spondylodiscitis or epidural abscess 100%.

Conclusions: Although rare, infectious spondylodiscitis is a serious complication in haemodialysis patients with a CVC as vascular access. It is essential that any alarming sign of infection to be recorded daily and appropriate treatment to initiate in order to avoid fatal complications.
