Insights
Chagas disease, caused by Trypanosoma cruzi, is an emerging threat in the US, with poor medical awareness. Targeted screening and prompt evaluation are recommended for at-risk individuals to prevent disease progression.
Area of Science:
- Infectious Diseases
- Parasitology
- Public Health
Background:
- Chagas disease (caused by Trypanosoma cruzi) is a growing global concern, with an estimated 300,000 infected individuals in the US.
- Awareness of Chagas disease among US healthcare providers is notably low.
Purpose of the Study:
- To review the clinical experience of managing Chagas disease patients in the New York City metropolitan area.
- To describe screening methods, clinical presentations, diagnostic findings, and treatment outcomes for Chagas disease.
Main Methods:
- Retrospective review of 60 Chagas disease patients managed in New York City hospitals.
- Analysis of patient demographics, country of origin, detection methods, clinical manifestations, EKG and imaging findings, and treatment regimens.
Main Results:
- The majority of patients originated from El Salvador (40%), with blood donor screening being a common detection method (35%).
- Nearly half of the patients (48%) were asymptomatic at diagnosis.
- Treatment with benznidazole or nifurtimox was initiated in 27 patients, but 7 did not complete therapy due to side effects or loss to follow-up. Ten patients developed advanced heart failure.
Conclusions:
- Recommend targeted screening for asymptomatic, at-risk populations to enable early detection before clinical disease progression.
- Advocate for comprehensive evaluation including electrocardiogram, echocardiogram, chest x-ray, and relevant gastrointestinal imaging.
- Emphasize appropriate patient treatment while cautioning providers about potential adverse effects that may hinder treatment completion.
Background:
Chagas disease, caused by the parasite Trypanosoma cruzi, once considered a disease confined to Mexico, Central America, and South America, is now an emerging global public health problem. An estimated 300 000 immigrants in the United States are chronically infected with T. cruzi. However, awareness of Chagas disease among the medical community in the United States is poor.
Methods:
We review our experience managing 60 patients with Chagas disease in hospitals throughout the New York City metropolitan area and describe screening, clinical manifestations, EKG findings, imaging, and treatment.
Results:
The most common country of origin of our patients was El Salvador (n = 24, 40%), and the most common detection method was by routine blood donor screening (n = 21, 35%). Nearly half of the patients were asymptomatic (n = 29, 48%). Twenty-seven patients were treated with either benznidazole or nifurtimox, of whom 7 did not complete therapy due to side effects or were lost to follow-up. Ten patients had advanced heart failure requiring device implantation or organ transplantation.
Conclusions:
Based on our experience, we recommend that targeted screening be used to identify at-risk, asymptomatic patients before progression to clinical disease. Evaluation should include an electrocardiogram, echocardiogram, and chest x-ray, as well as gastrointestinal imaging if relevant symptoms are present. Patients should be treated if appropriate, but providers should be aware of adverse effects that may prevent patients from completing treatment.
