ABSTRACT
Abstract Chagas disease (CD) is caused by the protozoan Trypanosoma cruzi and affects about six to seven million individuals worldwide. The distribution of cases is concentrated mainly throughout Latin America, especially in rural areas. This study aims to evaluate microRNAs (miRNAs) as indicators in CD diagnosis for possible contributions to its management. This is a literature review study, carried out in the PubMed, SciELO, Bireme Library, NCBI, Science Direct, and Embase databases, through which a total of 12 articles were included for qualitative analysis. The discussion of this review was based on the thematic axes regarding the modulation of T. cruzi in the immune system and the expression of miRNAs, their production and action, the modulation mechanism of host gene expression, how they act as biomarkers, the importance of miRNAs in the diagnosis of CD, and how their regulation occurs in Chronic Chagas Cardiomyopathy (CCC). Moreover, T. cruzi infection is associated with the downregulation of several miRNAs, which directly related to the findings of hypertrophy and fibrosis. When quantified, these could be used as consistent indicators for CD to support the diagnosis of patients with CD complications, as well as a possible therapeutic target. However, the need for clinical studies that evaluate the usefulness of this biomarker in humans is emphasized, considering that in the present study, only experimental in vitro studies were evaluated, reflecting a lack of studies with practical applicability.
