Autonomic neuroimmunomodulation in chagasic cardiomyopathy

Experimental Physiology
Marcus Paulo Ribeiro Machado, Valdo Jose Dias da Silva

Abstract

Chagas disease is an endemic parasitic disease, caused by the flagellate protozoan Trypanosoma cruzi, with a high prevalence in Latin America. During its chronic phase, chronic chagasic cardiomyopathy is the most apparent clinical form, affecting 25-30% of patients. This clinical form may present as congestive heart failure, thromboembolic phenomena, cardiac arrhythmias and sudden death. Pathological findings in the heart include mononuclear inflammatory infiltrate, focal myocarditis, epicarditis and neuroganglionitis, associated with variable focal fibrosis and widely variable autonomic dysfunction. The immune-inflammatory response has been considered to be the cause of the autonomic dysfunction, which may trigger life-threatening arrhythmias and sudden death. In the last few years, several reports in the literature have described the marked role played by the autonomic nervous system in the modulation of the immune-inflammatory response in some experimental models of infectious, ischaemic and autoimmune diseases. However, nothing is known about this autonomic neural modulation of the immune response in Chagas disease. In the present report, we discuss several sets of evidence suggesting that changes in the autonomic drive dir...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
