Descrição: dc.descriptionPro-inflammatory immune response is usually associated with Chagas disease pathogenesis, but is also relevant to treatment effectiveness. Cross-sectional studies have suggested that this activated state may persist for years after therapeutic intervention. However, short-term longitudinal investigation has suggested that the Benznidazole treatment (Bz-treatment) leads to decreased immunological activation. In order to elucidate this issue, we performed a longitudinal study to evaluate the immunological status following Bz-treatment during early indeterminate Chagas disease. Our results demonstrated that Bz-treatment led to higher activation status of circulating monocytes but was negatively associated with the number of IL-12þCD14þ cells. Moreover, Bz-treatment triggered a high frequency of circulating CD3_CD16þCD56_ NK cells, in addition to elevated activation status associated with a type 1-modulated cytokine pattern. Bz-treatment induced substantial T and B-cell activation status associated with an overall IL-10 modulated type 1 cytokine profile. In summary, these findings provide new information regarding immune activation status following the etiological treatment of Chagas disease. These results suggest that in addition to the increased number of activated leukocytes in the peripheral blood, Bz-treatment may also involve a qualitative change in their functional capacity that drives their activation state toward a modulated cytokine profile. These changes may account for the benefits of etiological treatment of Chagas disease.-
