Design outcomes

Primary

MeasureTime frame
Main Objective: ? To compare the evolution of the parasite load at baseline and during therapy with benznidazole and in the following 16 months after therapy, in treated and untreated patients. ? To compare the evolution of the specific immune response against T. cruzi at baseline and during therapy with benznidazole and in the following 16 months after therapy, in treated and untreated patients.;Secondary Objective: ? To evaluate and standardized molecular and immunological techniques for use in clinical practice. ? To describe the safety profile of treatment with benznidazole. ? To evaluate quantitative PCR and the specific immune response against T. cruzi as long term response surrogate markers.;Primary end point(s): The change in parasite load from baseline by quantitative PCR and the development of a specific immune response against T. cruzi analising of the frequency of T. cruzi specific T-cells secreting ?-IFN and IL-2, as well as measurements of the degree of activation of CD4 and CD8 T lymphocytes and B lymphocytes.;Timepoint(s) of evaluation of this end point: At baseline, day +15, day +60, month +5, month +11 and month +18.

Secondary

MeasureTime frame
Secondary end point(s): Adverse events reported;Timepoint(s) of evaluation of this end point: Day +15 and day +60.
