Human brucellosis in Tuzla Canton.

ABSTRACT

INTRODUCTION: The prevalence of human brucellosis in Bosnia and Herzegovina and the Tuzla Canton reached its peak in 2008, with a reported total of 994 cases within country, and with 104 cases within the Tuzla Canton. AIM: to analyze the clinical and epidemiological features of human brucellosis in patients hospitalized at the University Clinical Center Tuzla during the period from 01/01/2000 till the 31/12/2010. METHODS: We retrospectively analyzed the clinical symptoms, the laboratory and X-ray findings, the treatments, and the course and outcome of the disease. The diagnosis of brucellosis was based on anamnesis, clinical presentation, in correlation with a positive blood-culture, and/or serological tests. RESULTS: The majority of patients (93.18%) were from rural regions. There were more males (79.54%) than females. Most of the patients were aged between 30 to 39 years (21% cases). Contact with infected animals was registered for 83.40% of the patients. The main symptoms and signs were fever, joint-pains, night sweating, anorexia, headaches, and hepatosplenomegaly. The important laboratory findings were increased erythrocyte sedimentation rates, increased values of C-reactive protein, and anemia. Adult patients were treated with a combination of gentamicin or streptomycin with doxycycline, and the children with a combination of gentamicin, and trimethoprim-sulfametaxasol, over at least 6 weeks. Complications were documented in 20.45% of the patients. Relapses were observed in 14.20%, and a chronic form of brucellosis in 5.11% of patients. There were no cases with lethal outcomes. CONCLUSION: Brucellosis is a growing public health problem, not only within the Tuzla Canton, but throughout Bosnia and Herzegovina.
