Research Study For Children Adopted From Guatemala

What is the purpose of this study?

Cincinnati Children’s is conducting a research study to determine how many children adopted from Guatemala have Chagas disease.  Chagas disease is caused by Trypanosoma cruzi. T. cruzi is a parasite that is found in parts of Central and South America, and Mexico. If left untreated, it can lead to heart and nervous system problems.

Who can participate?

Children and adolescents who have been adopted from Guatemala and are at least 1 year of age may be eligible to participate.


  • Anxiety Disorders
  • Other

What is involved?

The study includes 1 visit to the International Adoption Center at Cincinnati Children’s Hospital Medical Center.  The following is a list of procedures that will take place during the study:

  • Your child will have blood drawn.
  • Your child’s blood test results will be reported to you by a staff member.
  • If your child’s test results are positive, he/she will be referred to the International Adoption Center to discuss treatment of Chagas disease.

What are the benefits?

  • Learning if your child has Chagas disease may lead to early treatment and help prevent complications
  • Information learned from this study may help determine if screening for Chagas disease is needed in this population

Will I get all the facts about the study?

Parents interested in having their child participate will be given a consent form that thoroughly explains all of the details of the study.  The form covers all of the procedures, the risks, the benefits, compensation, who to contact with questions or concerns and more.  A member of the study staff will review the consent form with you and will be sure that all of your questions are answered.  Study procedures will not begin until a parent or guardian has signed this form and, if of age, the child has given at minimum his/her verbal agreement.

What are the risks and discomforts of the study?

  • Risks associated with a blood draw
  • You may worry if you find out your child has Chagas disease. Counseling will be available through the IAC.

Do participants receive pay, compensation or reimbursement?

All study-related testing will be provided at no cost.
