Abstract

Background

In the Amazon region, there has been a significant increase in the number of acute Chagas disease (ACD) leading to electrocardiographic and echocardiographic abnormalities. The main pathophysiological mechanisms involved in Chagas cardiomyopathy (CCM) are microvascular dysfunction, Autonomic Nervous System (ANS) dysfunction, direct parasite aggression, and inflammatory activity. Chagas disease (CD) is a perfect example of inflammatory cardiomyopathy that might influence changes in metabolic parameters and ANS. Studies on the measurement of adipocytokines and insulin levels in humans with ACD are scarce.

Objective

To evaluate adiponectin, leptin and insulin levels before and after the treatment of ACD with benznidazole and to correlate with ANS and cardiac function.

Methods

Twenty-eight subjects were divided into groups: control group (CG), with 15 subjects, and ACD group, with 13 subjects. All subjects underwent a standard 12-lead ECG, comprehensive transthoracic echocardiographic, evaluation of autonomic function and serum adiponectin, insulin and leptin levels. A level of significance of 5% (p-value < 0,05) was used.

Results

Insulin levels were lower in the ACD group both before and after the treatment when compared to the control group and lower in the post-treatment phase when compared to the pre-treatment phase. Adipocytokine, leptin and adiponectin levels showed no differences between groups.

Conclusion

Insulin levels were lower in the ACD group both before and after the treatment when compared to the control group and lower in the post-treatment phase when compared to the pre-treatment phase. There was no significant correlation between adipocytokine and insulin levels with cardiac function and the ANS parameters.

An Approach to The Acute Phase of Chagas' Disease: The Continuing Challenge it Presents in the 21(st) Century

Dário C. Sobral Filho

Chagas disease, in addition to being widespread on the American continent with around six million persons infected, is currently present in various regions of the world as a result of the migration of individuals with the disease.,

The statistics show that the incidence of acute cases has fallen from 700,000 new cases in 1990 to the current estimate of 29,000 – 30,000 per year by vector-borne transmission, plus 8,000 other cases by other modes such as transfusion and the digestive tract, owing to ingestion of food contaminated by Trypanosoma cruzi, as described by Ortiz et al. in their publication in this journal, in which they report 63 cases of cases of the acute form of Chagas disease in the state of Amazonas over a period of eight years, with oral transmission in 75% of the patients.

Ideal Cardiovascular Health and Job Strain: A Cross-Sectional Study from the Amazon Basin

Davi Dantas Muniz et al. Kamile Santos Siqueira Cristina Toledo Cornell Miguel Morita Fernandes-Silva … Pascoal Torres Muniz Odilson Marcos Silvestre

Abstract

Background:

Ideal Cardiovascular (CV) Health is characterized by four ideal lifestyle parameters and absence of cardiovascular risk factors. The prevalence of ideal CV health in the Amazon Basin and the influence of job strain on CV health in this setting are uncertain.

Objective:

To evaluate the prevalence of ideal CV health and its relationship with job strain in a secluded area from a developing country.

Methods:

Job strain was evaluated in 478 employees from an university in the Amazon Basin by a questionnaire that classified participants as passive, active, low or high strain, according to the demand-control model. CV health was evaluated using the American Heart Association 7 health factors (diet, physical activity, body mass index (BMI), smoking, hypertension, diabetes and hypercholesterolemia). Participants were classified as having ideal, intermediate or poor CV health. The level of significance was set at p < 0.05.

Results:

The mean age was 44.3 ± 12 years, 65% were men, and 35% were faculty. No participant fulfilled the criteria for ideal CV health. Intermediate CV health was found in 44 (9%) and poor in 434 (91%) individuals. Considering low strain as a reference group, individuals classified as high strain, active and passive had a non-significant (p > 0.05) increase in the chances of having poor CV health. When adjusting for possible confounders, high job strain was associated with poor BMI (> 30 kg/m2), (OR 2.11, 95%CI 1.06-4.22; p = 0.034) and poor diet (OR 2.31, 95% CI 1.29-4.13; p = 0.005).

Conclusion:

Job strain was not associated with cardiovascular health, but high job strain was related to obesity and poor diet. Given the high prevalence of poor CV health and lack of participants with ideal CV health, policies focusing on health education and lifestyle interventions are paramount to this population.
