Abstract
Chronic Chagas heart disease (CCHD affects about 30% of patients with chronic Chagas disease (CCD). Systemic arterial hypertension (SAH) afflicts about 25% of patients with CCD. The association of CCHD with SAH (CCHD-SAH) predisposes patients to develop chronic heart failure. The role of cytokines in disease progression in patients with CCHD-SAH is unknown. Accordingly, the aim of this study was to evaluate the plasma levels of cytokines expressing the Th1, Th2, Th17 pattern, as well as Treg cytokines, TNF-alpha, IL-1β, IL-8, IL-7 in patients with SAH-CCHD to get insight into the immunomodulation process in patients with this condition. Fifteen patients with CCHD, 22 patients with CCHD-SAH, and 28 controls were studied. All patients underwent history-taking, physical examination, 12-lead resting ECG, chest X-ray, and Doppler-echocardiogram. Ten of 15 (66%) patients with CCHD, and 16 of 22 (73%) patients with CCHD-SAH had decreased left ventricular ejection fraction (p > 0.05). Cytokines levels were performed on plasma samples using the ELISA method. Overall, proinflammatory, anti-inflammatory, and regulatory cytokine levels were increased in patients with CCHD-SAH in comparison to patients with CCHD and controls. However, such a difference was higher regarding IL-2, IL-5, IL-17, IL-12, and TNF-alpha cytokine levels, respectively. Cytokine levels were higher in CCHD patients in comparison to controls. Patients with CCHD-SAH have increased plasma levels of pro-inflammatory, anti-inflammatory, and regulatory cytokines in comparison with CCHD patients, thus suggesting a higher level of immunomodulation in patients with CCHD-SAH.
