Resumen:
Background: Intraventricular conduction disturbances are common in patients with Chagas disease and preserved left ventricular ejection fraction, but their association with higher inflammatory activity is unknown. Objectives: The aim of this study was to determine the presence of an association between interleukin levels and intraventricular conduction disturbances in patients with positive serology for Chagas disease and preserved left ventricular function. Methods: Twenty-two patients between 22 and 80 years of age with positive serology test for Chagas disease of more than 20 years progression and left ventricular ejection fraction ≥50% were included in the study and compared with a control group of 14 healthy individuals. Plasma levels of IFN-γ, IL-1β, IL-6, IL-10, IL-12 (p70), IL-15, IL-17A, MCP-1/CCL2, MIP-1 α/CCL3, TNF α and IL-2 were measured in patients and controls. Right bundle branch block, left anterior hemiblock or left bundle branch block were considered intraventricular conduction disturbances. Results: Among the 22 patients with positive serology for Chagas disease, 10 presented intraventricular conduction disturbances (45.4%). This group had elevated levels of interleukins with high inflammatory effect, such as INF-γ, IL-15, IL-2, IL-12, MIP-1 α, compared with the control group, and high levels of IL-10 as a regulatory mechanism of an excessive immune response. Conclusions: The association between elevated levels of inflammatory interleukins and intraventricular conduction disturbances suggests that chronic inflammation may play a role in the development of these abnormalities in patients with positive serology for Chagas disease and preserved left ventricular ejection function.
