Purpose

The survival of children who have received heart transplants has greatly improved over the last ten years. One reason for this is better control over rejection. Rejection medications require a delicate balance of enough medicine to work without causing side effects. It is a goal to avoid both rejection and side effects from the anti-rejection medicines. Usually several medicines are used together to prevent rejection. One of these medicines is often Mycophenolic Acid or CellceptThis medicine has been used longer for adults than is has for children. More information is needed on using it for children. The dose is usually determined by the patient’s weight or body surface area.

There have been some early studies of the use of Cellcept, but none have proven a relationship between the blood level of the drug and how well it works. More also needs to be known about how this drug works with other anti-rejection drugs and how it works in boys and girls. This study will look more closely at proper dosing, how Cellcept works with other anti-rejection medications, side effects, and any differences in how this medicine works in boys and girls.

All patients in the study will be receiving Cellcept and have blood levels of the drug drawn. Results of their usual treatment and testing will be recorded and evaluated for signs of rejection. All the information will be analyzed. Results of this study will be reported to transplant committees locally and nationally.

Official Title:	The Relationships Between Mycophenolic Acid Levels, T-Cell Subsets and Outcomes in Pediatric Heat Transplant Recipients Receiving Mycophenolate Mofetil (Cellcept)

Further study details as provided by Emory University:

Primary Outcome Measures:

Examine t-cell subsets to determine the correlation between MIP levels and clinical outcome as well as effect on T-cell proliferation.

Secondary Outcome Measures:

Examine histologic grading of routine endomyocardial biopsies to determine the correlation between MPS levels and acute rejections.

Estimated Enrollment:	30
Study Start Date:	January 2003
Estimated Study Completion Date:	May 2005

Detailed Description:

Pediatric heart transplant recipients receiving MMF will undergo study testing to measure MPA levels by the HPLC method and T-cell subsets by flow cytometry method. As standard of care they receive histological grading of routine endomyocardial biopsies using the International Society of Heart Lung Transplantation (ISHLT) grading scale. The data obtained from standard assessments will include medications, echocardiographic reports, pre-and post biopsy assessments/physical exams, hospital records for any inpatient hospitalization, and any laboratory assessments. Also, information will be collected on all patients which will be examined for tolerance and success (side effects and rejection) of immunosuppressive therapy.

In newly transplanted patients, study testing will occur at the same time as standard of care biopsies which are typically 1 week, 2 weeks, 3 weeks, 4 weeks, 6 weeks, 8 weeks, 3 months, 4 months, 5 months, 6 months, 8 months, 10 months, 12 months. If the patient has additional visits due to rejection or changes in immunosuppression, then more frequent study testing may be done per investigator preference. Previously transplanted patients will have study testing at the same time as their standard of care visits, usually annually.
