Brucellosis of the spine - A global public health problem - An analysis of 37 patients from a 'high risk' region.

BACKGROUND

Brucellosis is a global public health issue. Brucellosis of the spine presents as a wide spectrum. The aim was to present the outcome analysis of patients treated for Spinal Brucellosis in the endemic region. Secondly to assess the accuracy of IgG and IgM Elisa in the diagnosis.

RESULTS

A retrospective study of all patients who were treated for Brucellosis of the spine from 2010 to 2020 was conducted. Confirmed cases of Brucellosis of spine and who had adequate follow up after completion of treatment were included. The outcome analysis was based on clinical, laboratory and radiological parameters. There were 37 patients enrolled with a mean age of 45 and an average follow up of 24 months. All of them presented with pain and 30% had neurological deficits. Surgical intervention was done in 24%(9/37patients). All the patients were treated with triple drug regimen for an average duration of 6 months. Those patients with relapse had a 14month period of triple drug regimen. The sensitivity and specificity of IgM was 50% and 85.71%. The sensitivity and specificity of IgG was 81.82% and 7.69%.76% of them had good functional outcome and 82% of them had near normal neurological recovery and 97.3%(36 patients) were healed of the disease with relapse in one patient(2.7%).

CONCLUSIONS

Majority (76%) of the patients with Brucellosis of the spine were treated conservatively. Average duration of treatment of triple drug regimen was 6 months. The sensitivity of IgM & IgG was 50% and 81.82% The specificity of IgM and IgG was 85.71% and 7.69% respectively.
