Aim: The objective of this study was to analyse the presentation, aetiology, diagnosis, management, and outcome of infectious discitis.
Methods: A screening prospective case‐finding study was carried out at Al‐Yarmouk teaching hospital in Baghdad, Iraq from 1997 to 2006. Fifty adult patients (12 men and 38 women) were diagnosed with infectious discitis from different referral sources. The diagnosis was based on laboratory biochemical tests, isolation of micro‐organisms from blood and needle aspiration tissue, and radiological investigations including magnetic resonance images (MRI).
Results: Of the 50 cases, 32 (64%) patients presenting within 4 weeks, 94% had pelvic and abdominal surgical interventions, 70% presented with severe neck pain and 36% had neurological deficits. Marked elevation of erythrocyte sedimentation rate and high serum C‐reactive protein levels were observed in all patients. Positive blood, percutaneous disc aspiration and surgical exploration samples for Staphylococcus aureus, Streptococcus viridans, E. coli, Pseudomonas aureginosa and Candida albicans were found. Radiological images showed that disc involvement did not exceed more than one intervertebrate disc with two adjacent vertebrae. The clinical outcome was full recovery (86%), residual neurological deficits (10%) and death (4%).
Conclusions: Infectious discitis in adults should be suspected in every case presenting with severe neck or back pain, followed by pelvic or abdominal surgical interventions. Therefore, MRI techniques should be performed on every case and an early empirical antibiotic therapy is advised.
