Methods: We studied retrospectively 87 patients hospitalized in the Department of Infectious Diseases between 1995 and 2013. They were divided into 2 groups: G1 (57 patients with TS; 65.5%) and G2 (30 patients with BS; 34.5%). Clinical, radiological and biological characteristics were collected in 2 groups as well as management and outcome features.
Results: The mean age of patients was similarly in 2 groups (46.9±19 vs. 50.5±15 years; p=0.3). There were 25 males (43.8%) in G1 and 22 males in G2 (73.3%; p=0,009). Four TS patients had a previous history of tuberculosis (7%). Ingestion of unpasteurized milk was more frequent in G2 (43.8 vs.93.3%; p<0.0001 and OR=20). Fever and sweats were predominant in BS patients (43.8 vs. 66.7%; p=0.04 in each case). Neurological symptoms had shown no difference between 2 groups. There was no BS patient suffering from spinal cord compression (vs. 9 TS patients (15.8%); p=0.025). White blood cells counted 8154±3614 E/mm3 in G1 (vs. 6142±1832 E/mm3 in G2; p=0.001). Wright Serology was positive in all BS patients (100%). Discovertebral biopsy was performed in 36 TS patients (63.1% vs. 26.7%; p=0.001). BS involved predominantly lumbar vertebrae (45.6 vs. 83.3%; p=0.001) while dorsal level was more frequently affected in TS (54.3 vs. 26.7%; p=0.013). The mean duration of treatment was far longer in G1 (13.3± 5.8 vs. 7.5±3 months; p<0.0001). Eleven TS patients (19.3%) were referred to surgery while no BS patient needed surgical treatment (p=0.014). Sequelae were noted similarly in 2 groups (67.5 vs. 50%; p=0.1).
Conclusion: Our study underlined the difficulty of etiological diagnosis in cases of spondylodiscitis especially in areas with a high prevalence of brucellosis. Further studies are in need to help physicians in these cases.
