    Abstract:
    The aim of this study was to retrospectively evaluate the clinical and laboratory characteristics, complications and treatment oucomes of 151 brucellosis cases (age range: 15-79 years; 89 female), who were followed in our clinic between the period of January 2003-July 2005. Of them, 66.2% were diagnosed as acute, 23.8% as subacute and 9.9% as chronic brucellosis. Risk factors were detected as consumption of unpasteurized milk and diary products (80%), stock-breeding (14%) and risky profession such as veterinary, laboratory technician and butcher (3.3%). Most common complaints were arthralgia (87.4%), malaise (86%), fever (79.5%), sweating (78%), and waist pain (71%). In view of laboratory findings, increased erytrocyte sedimentation rate was detected in 61.6%, C-reactive protein positivity in 60%, lymphomonocytosis in 44.4% and anemia in 51.7% of them. Blood cultures were performed from 125 of the patients, and 64 (51.2%) of them yielded Brucella spp. The other specimens in which bacterial growth were detected in one of each, were bone marrow, sternoclavicular joint, psoas abscess, urine and pleural fluid. Standard tube agglutination (STA) test was found negative in 1.3% of patients who were culture positive, while it was positive at 1/160 titer in 20.5%, at 1/320 in 14%, at 1/640 in 14.6% and > or = 1/1280 in 49.7 percent. The most common complication was found as musculo-skeletal system involvement (30 spondylodiscitis, 15 sacroileitis, five peripheric arthritis, one tendinitis) with a rate of 33.7 percent. Other complications were nervous system involvement in 6% (two acute and seven chronic meningitis), genitourinary involvement in 5.3% (five epididymo-orchitis, two prostatitis, one with Brucella positive urine culture), peritonitis in 0.6% and skin involvement in 0.6 percent. Seven different therapy protocols were applied to the patients according to complications and case specialty, however doxycycline+rifampicin combination during six weeks was the most preferred one. Relapse and unresponsiveness to the therapy were detected in 8% and 2% of the cases, respectively. Gastrointestinal intolerance was found as the most common side effect. In conclusion, since brucellosis which is endemic in Turkey, displays diagnostic difficulties due to the various clinical presentations and leads to labor loss due to serious complications, it should be considered in the differential diagnosis of numerous diseases.
