Insights
This study found lower insulin levels in acute Chagas disease (ACD) patients before and after treatment. No significant correlation was found between metabolic parameters and cardiac or autonomic function in ACD.
Area of Science:
- Cardiology
- Infectious Diseases
- Metabolic Syndrome
Background:
- Acute Chagas disease (ACD) is rising in the Amazon, causing cardiac abnormalities.
- Chagas cardiomyopathy (CCM) involves microvascular and autonomic nervous system (ANS) dysfunction.
- Limited research exists on metabolic parameters like adipocytokines and insulin in ACD.
Purpose of the Study:
- To assess adiponectin, leptin, and insulin levels pre- and post-benznidazole treatment for ACD.
- To correlate these metabolic markers with ANS and cardiac function.
Main Methods:
- Compared 13 ACD patients with 15 controls.
- Evaluated ECG, echocardiography, ANS function, and serum adiponectin, insulin, and leptin.
- Statistical significance set at p < 0.05.
Main Results:
- Insulin levels were significantly lower in ACD patients compared to controls, both before and after treatment.
- Insulin levels further decreased after treatment in the ACD group.
- Adiponectin, leptin, and adipocytokine levels did not differ between groups.
Conclusions:
- Lower insulin levels characterize ACD, persisting post-treatment.
- No significant correlation was observed between adipocytokines, insulin, and cardiac/ANS parameters in ACD patients.
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.
