Seroprevalence of Brucellosis in Human Immunodeficiency Virus Infected Patients in Hamadan, Iran.

ABSTRACT

OBJECTIVES: Brucellosis is a systemic disease with a wide spectrum of clinical manifestations. This study aimed to determine the seroprevalence of brucellosis in human immunodeficiency virus (HIV) infected patients in Hamadan Province in the west of Iran. METHODS: A total of 157 HIV-infected patients were screened through standard serological tests, including Wright's test, Coombs' Wright test, and 2-mercaptoethanol Brucella agglutination test (2ME test), blood cultures in Castaneda media, and CD4 counting. Data were analyzed using Stata version 11. RESULTS: Wright and Coombs' Wright tests were carried out, and only 5 (3.2%) patients had positive serological results. However, all patients had negative 2ME results, and blood cultures were negative for Brucella spp. Moreover, patients with positive serology and a mean CD4 count of 355.8 ± 203.11 cells/µL had no clinical manifestations of brucellosis, and, and the other patients had a mean CD4 count of 335.55 ± 261.71 cells/µL. CONCLUSION: Results of this study showed that HIV infection is not a predisposing factor of acquiring brucellosis.
