Brucellar Spondylodiscitis -: Mri Diagnosis
(Elsevier Science inc, 2001) Harman, M; Unal, Ö; Onbasi, KT; Kiymaz, N; Arslan, H
Early diagnosis of bruccellar spondylodiscitis is often difficult because of the long latent period. Radiographs of the spine, bone scan, and computed tomography (CT) scan provide insufficient data. Among 25 patients with brucellar spondylodiscitis studied by magnetic resonance imaging (MRI), 9 were in the acute stage and 16 were in the chronic stage. MRI is the investigation method of choice in diagnosing brucellar spondylodiscitis. (C) 2001 Elsevier Science Inc. All rights reserved.
Change in Serum Concentrations of Interleukin-2 and Interferon-Γ During Treatment of Tuberculosis
(Cambridge Med Publ, 2004) Berktas, M; Guducuoglu, H; Bozkurt, H; Onbasi, KT; Kurtoglu, MG; Andic, S
We aimed to investigate changes in serum concentrations of the cytokines interleukin (IL)-2 and interferon (IFN)-gamma during the clinical course of active tuberculosis, to establish the presence of cellular immunity before and after treatment. Blood samples were taken from 18 patients with active tuberculosis before and 2 months after therapy; IL-2 and IFN-gamma concentrations were evaluated. The mean serum IL-2 concentration before therapy was 164.5 pg/ml (range 12 - 980 pg/ml) and the concentration 2 months after therapy was 92.11 pg/ml (range 1 - 490 pg/ml). The mean serum IFN-gamma concentrations were 10.83 pg/ml (range 1 - 22.2 pg/ml) and 4.64 pg/ml (range 1 - 28.5 pg/ml), respectively. The decrease in concentrations of both cytokines after therapy was statistically significant. Further studies investigating the benefits of adding cytokines to drug treatment for tuberculosis are needed.
