Chagas disease, also known as American trypanosomiasis, is an infectious disease that affect various organs.
General
- Essentially a South American disease.
- Etiology: protozoa Trypanosoma cruzi - transmitted by reduvid bugs,[1] also known as kissing bug.[2]
Clinical:[3]
- Depends on phase of infection.
- Arrhythmias (late).
- Toxic megacolon.[4]
- Chagas disease esophagopathy.[5]
- Achalasia-like pathology with dilation of the esophagus.
Dx:[6]
- Usually serology.
- Thin blood smear.
Tx:
- Antimicrobials: benznidazole, nifurtimox.[1]
Microscopic
Features - heart:
- Inflammation - main finding.[3]
- Intramuscular organisms (without an inflammatory response).
- Neuronal loss in atrial ganglia.[7]
DDx:
- Toxoplasmosis.[8] (???)
Images:
IHC
- Anti–T cruzi immunoperoxidase.[7]
