    Assessment of diagnostic enzyme-linked immunosorbent assay kit and serological markers in human brucellosis
    (2008) Cakan G.; Bezirci F.B.; Kacka, A.; Cesur, S.; Aksaray, S.; Tezeren, D.; Saka, D.; Ahmed, K.
    This study was performed to evaluate commercial brucella immunoglobulin G and M-enzymelinked immunosorbent assay (IgG and IgM ELISA) kits for the diagnosis of human brucellosis and to suggest a candidate prognostic marker for human brucellosis. We determined the serum levels of brucella IgG, IgM, C-reactive protein (CRP), soluble CD14 (sCD 14), and neopterin in patients with brucellosis and compared them with those of normal healthy persons, patients with tuberculosis, and patients with other diseases. It was found that the sensitivity of ELISA to diagnose brucellosis was high when both IgG and IgM ELISA were used together. This study showed that serum CRP, sCD14, or neopterin levels were significantly high during the course of human brucellosis. The above markers, alone or in combination, might have the potential to evaluate treatment outcomes in human brucellosis. The markers that can predict the variability of agglutination titer was also determined. It was found that the titer value alone does not fully represent disease status.

    Serum adenosine deaminase levels in patients with brucellosis and in healthy subjects
    (TÜBİTAK, 2004) Cesur, S.; Sunguroğlu, K.; Ahmed, Kamruddin; Tezeren, D.; Keseci, N. O.; Aksaray, S.
    The aim of this study was to determine the serum adenosine deaminase (ADA) levels in patients with brucellosis and compare them with the results of healthy individuals. Forty-eight subject were enrolled in this study : 34 patients with brucellosis and 14 healthy individuals. Serum ADA activity was assessed by spectrophotometer in patients with brucellosis and statistically compared with that of healthy individuals. A normal range of serum ADA was considered 5-35 IU/I. Serum ADA levels were also compared with Brucella agglutinations titers and serum C reactive protein (CRP). Serum ADA levels were found to be significantly higher in patients with brucellosis than in healthy individuals (43.45 ±24.19 IU/I and 27.5 ± 9.3 IU/I, respectively) (P < 0.01). Serum ADA activity did not show any correlation between the Brucella agglutination titer and CRP level. Serum ADA level showed significant alterations in patients with brucellosis compared to healthy subjects. We concluded that serum ADA level may be used in the follow up of patients with brucellosis together with clinical and other laboratory findings.
