Chagas cardiomyopathy associated with serological cure after trypanocidal treatment during childhood

Area of Science:

• * Infectious Diseases
• * Cardiology
• * Parasitology

Background:

• * Chagas disease, caused by Trypanosoma cruzi, is a chronic parasitic infection with potential cardiac complications in about one-third of cases.
• * Benznidazole and nifurtimox are standard treatments for Trypanosoma cruzi infection.
• * Cure is traditionally defined by sustained negative serological tests post-treatment.

Observation:

• * A case study of a patient treated for Chagas disease at age 13.
• * The patient achieved seroconversion, indicating successful eradication of Trypanosoma cruzi.
• * Despite initial cure, the patient later developed Chagas disease cardiomyopathy in adulthood.

Findings:

• * Negative seroconversion after treatment does not guarantee the absence of long-term cardiac sequelae.
• * Chagas disease cardiomyopathy can manifest years after apparent cure.
• * This case challenges the conventional criterion for cure in Chagas disease.

Implications:

• * Long-term cardiac monitoring is crucial for individuals treated for Chagas disease, irrespective of initial serological cure.
• * Re-evaluation of cure criteria and long-term follow-up strategies for Chagas disease is warranted.
• * Understanding the pathogenesis of late-onset cardiomyopathy in treated Chagas disease patients is essential for improved patient outcomes.
