Rheumatologic manifestations of brucellosis

Abstract

Brucellosis, an endemic disease in certain parts of the world is usually accompanied by osteoarticular involvement. The present study was performed to determine the types and frequency of rheumatologic manifestations in patients with brucellosis diagnosed in the north of Iran. Diagnosis of active brucellosis was based on the serological tests along with compatible clinical findings. Musculoskeletal involvement of brucellosis was confirmed by clinical and radiographic examinations; 51 (32 males, 19 females) patients with mean (SD) age of 35 (19) years old were studied. Rheumatological manifestations were observed in 94% of patients. The most frequent skeletal findings in order of frequency were peripheral arthritis, sacroiliitis; and spondylitis which occurred in 37; 31 and 8% of patients, respectively. Back pain, arthralgia, myalgia, and enthesopathy were also reported in 49, 34, 11.7% of patients, respectively. Based on the findings of this study, rheumatologic manifestations are common in brucellosis; therefore, in the endemic areas, brucellosis should be considered in the differential diagnosis of patients who present with any type of rheumatologic manifestations.
