Objectives The aim of this study was to characterize the clinical, biological, imaging aspects and outcomes of infectious arthritis of sacroiliac joints in Tunisian individuals.
Methods A retrospective bicentric study involving cases of infectious arthritis of sacroiliac joint admitted to hospital between January 2002 and December 2011. Diagnosis was based on clinical examination and image, bacteriological and histological tests. Clinical, laboratory and radiological data, causative microorganism, treatment and outcome was identified.
Results We included 15 cases with septic sacro-iliitis; 9 males and 6 females. The mean age was 40,26 years (15 - 71 years). Six patients consume impasteurized milk and only one reported contact with family members known to have tuberculosis.
The most frequent symptoms are fever (86,7%) and fessialgy (80%). Pain in the sacroiliac mobilization and lameness are noted in 93,3% and 66% of patients.
Leucocitosis was present in 13,3% of patients; elevated ESR in 53,3% and elevated RCP in 40%.
Plain radiographies of 7 patients showed lesions that would suggest sacroiliitis, CT had confirmed this diagnosis in 9 patients and magnetic resonances in 6 patients. The lesion was bilateral in one case, associated with spondylodiscitis in 3 cases, and with psoas abscess in 3 cases.
The causative agent was isolated in 73,3% of patients, according to the haemocultures in 4 cases, sputum culture in one case, serology in 5 cases and nodes biopsy in one case.
The etiology was brucellosis in 5 cases, tuberculosis in 4 cases and Staphylococcus aureus in 4 cases. The causative germ was not identified in 2 cases.
Appropriate antibiotic therapy was effective for all the patients, none needed surgical treatment. None of the 15 patients showed evidence of a relapse of the lesion.
Conclusions Infection of sacro-iliac joint is a rare condition. Prompt diagnosis and appropriate antibiotherapy results in excellent outcome in most cases.
