14â16 The neuronal loss in Chagas heart disease has been postulatedto occur predominantly during the acute phase of the infec-tion, with participation of 3 mechanisms: direct parasitism ofneurons, degeneration caused by periganglionic inflamma-tion, and antineuronal autoimmune reaction.nly inthe late 1940s, through improved specific serological tests todetect antibodies against T cruzi, the clinical syndromes ofmegaesophagus, megacolon, and heart failure, by then ofunknown cause, were ascribed to Chagas disease, and the firstreport of cardiac neuronal damage appeared in the literature.
Chagas disease is caused by a parasite that is most likely found in Central or South America. This parasite, called Trypanosoma cruzi, is related to the African trypanosome that is known to cause sleeping sickness. This parasite is spread by reduvid bugs. It is a major health issue in South America. The United States may be affected by this disease because of international travel and immigration. Since 2007, many blood banks in the United States have been screening for Chagas disease.
