چکیده انگلیسی
This study was to follow IFN-γ, TNF-α and IL-10 modulation of peripheral blood mononuclear cells (PBMC) from HIV/cerebral toxoplasmosis patients (CT) during specific treatment. The results were compared with two other groups: HIV patients that had CT at least one year before (P/CT) and individuals with chronic toxoplasmosis (CHR). Blood samples (63) collected from three groups were analyzed. CT, 15 patients (3 blood samples collected one day before Toxoplasma gondii treatment; 7 and 15 days during the treatment). P/CT, 5 patients (one blood sample collected at least, one year after the treatment). CHR, 13 individuals with chronic toxoplasmosis (one blood sample). Cytokine levels were assessed by ELISA after PBMC stimulation with T. gondii antigen. CT patients had low IFN-γ; discrete increase at 7th and 15th days; and the levels were recovered in cured patients (P/CT). CT patients had high TNF-α in the beginning of the treatment. TNF-α levels decrease during the treatment (7th and 15th) and in those patients who were treated (P/CT). IL-10 levels were almost similar in CT and P/CT groups but low when compared with CHR individuals. The evolution of the infection was correlated to restoration of IFN-γ response and a decrease of the inflammation. The evaluation of the immune response can provide valuable information and better monitoring of patients during specific treatment.
