Clinical Manifestations and Laboratory Findings of Brucellosis at Boo-Ali-Siena Hospital of Ghazvin Province of Iran

[Background]Brucellosis as a zoonotic disease is controlled in many developed countries though it still remains endemic in the majority of Middle Eastern and developing countries.[Objectives]The purpose of this study was to identify the demographic features, clinical manifestations, and laboratory tests of patients diagnosed with brucellosis in Ghazvin province of Iran.[Methods]In this cross-sectional study, medical records of 83 cases with brucellosis (54 males and 29 females) over a 3-year period (from June, 2012 to June, 2015) were reviewed, retrospectively. Demographic features, clinical signs and symptoms, hematologic findings, and liver enzyme level were derived from the patients’ medical record.[Results]The mean age of cases was 42.5±18.3 years. Constitutional symptoms, which were noted in 45 (54%) cases, were the most common symptom of the disease. Clinical manifestations, including Sacroileitis, arthritis, and epididymo-orchitis were seen in 20 (24.1%), 10 (12%), and 7 (8.4%) cases, respectively. One case of Endocarditis (1.2%) was noted. Anemia as the most frequent blood abnormality was seen in 44 (53%) cases. Leukopenia and leukocytosis were noted in 17 (20.5%) and 9 (10.8%) patients, respectively. Thrombocytopenia and thrombocytosis were detected in 26 (31.3%) and 3 (3.6%) of the patients, respectively. Bicytopenia and pancytopenia were revealed in 9 (10.8%) and 11 (13.3%) cases, respectively. Elevated level of liver enzymes, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) were detected in 29 (34.9), 37 (44.6), and 51 (61.5) patients, respectively.[Conclusions]Brucellosis could affect every organ system of the human body. Variable manifestations and laboratory findings of brucellosis must be kept in mind, especially in endemic areas.
