Chagas disease is endemic to Latin America, and is of emerging importance in non-endemic countries because migration of people infected with T. cruzi. Current methods for diagnosis of T. cruzi infection are not ideal. Existing drugs for treatment are very limited, produce severe side-effects, and their effectiveness cannot be properly evaluated. Reliable biomarkers for prognosis, early diagnosis and effectiveness of treatment will be investigated.

Condition Intervention

Study Type: Observational
Study Design: Observational Model: Cohort

Further study details as provided by Barcelona Centre for International Health Research:

Primary Outcome Measures:
  • Biomarkers for prognosis, early diagnosis and effectiveness of treatment. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    • Conventional polymerase chain reaction of T. cruzi in blood
    • Measurement of Brain natriuretic factor
    • Measurement of Prothrombotic factors
    • Measurement of antibodies against specific proteins of the trypomastigote of T. cruzi
    • Investigation of the phylogenetics of the parasite and the role of the lineages of T.cruzi in the clinical presentation and disease's progression

Secondary Outcome Measures:
  • Cardiac function after antiparasitic treatment [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    - Correlation between biomarkers and alterations of the left ventricle diastolic function and segmentary contractility after antiparasitic treatment
