Design outcomes

Primary

MeasureTime frame
Expected therapeutic efficacy assessed from the parasitological response defined as sustained elimination of the parasite in 10 months of follow-up after or treatment determined by serial qualitative PCR results

Secondary

MeasureTime frame
To analyze the efficacy of treatment with Benznidazole at a dose of 300 mg/day for 8 weeks based on the genotyping of T. cruzi;To compare the safety of Benznidazole at a dose of 300 mg/day for 8 weeks in comparison with NFX at a dose of 600mg/day for 8 weeks without treatment of Chagas disease in the chronic phase in its indeterminate or mild cardiac forms;To assess parasitic kinetics by detecting parasitic DNA measured by qualitative PCR in peripheral blood at 4, 6, 8 and 12 months after the start of treatment in participants with chronic Chagas disease, in its indeterminate or mild cardiac forms treated with each um two or two therapeutic regimens;To measure longitudinal changes in the quality of life of two participants with Chagas disease in the chronic phase in its indeterminate or mild cardiac forms treated with each of two therapeutic regimens through two WHOQoL-BREF and EQ-5D-3 questionnaires;The frequency of adverse events that lead to discontinuation of treatment is expected to be evaluated.;To compare the efficacy of Benznidazole based on the geographic origin of the participant versus Nifurtimox
