Study for Children/ Teens Who Need Total Parenteral Nutrition

What is the purpose of this study?

Cincinnati Children’s is conducting a research study, sometimes known as a clinical trial or clinical study, to determine if infants, children and teenagers who need TPN because of their inability to absorb sufficient nutrients have lower bone mineral density than healthy children.

Who can participate?

Infants, children and teenagers 6 months to 17 years old in need of TPN to support their nutrition may be eligible to participate.


  • From 6 To 12  months old
  • From 1 To 17  years old


  • Weight/Nutrition

What is involved?

The study involves 1 or 2 study visits. The following outlines some of the procedures included in this study:

Your child will have:

    • His/her medical record reviewed 
    • His/her information collected such as weight, height, birth date, etc.
    • A special X-ray study of the bone
    • A tibial (lower leg) ultrasound, a painless procedure that uses ultrasound waves to take measurements to determine bone strength
    • Blood draws to help measure bone health, growth factors, etc.

You will:

    • Be asked to accompany your child to all study visits 
    • Be asked about your child’s medications, birth weight, diet, including TPN and formula, other medical conditions, etc.

What are the benefits?

Your child will not receive a direct benefit from participating in this research study. The information learned from this study may benefit other patients who are TPN dependent in the future.

Will I get all the facts about the study?

You 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, the pay, 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.

What are the risks and discomforts of the study?

Your child may experience some discomfort or become uncomfortable lying still during the DXA scan and tibial ultrasound. Also, there is slight risk of radiation exposure from the DXA scan. As the study includes blood draws, your child may experience some pain, bruising or temporary discomfort at the site of the blood collection.

Do participants receive pay, compensation or reimbursement?

Families will receive a $25 gift card for time and travel.
