Growth following solid organ transplantation in childhood

Area of Science:

• Pediatric medicine
• Transplantation immunology
• Growth and development

Background:

• Achieving optimal final adult height is a key goal in pediatric solid organ transplantation.
• Growth following transplantation is influenced by several common factors across different organ types.

Purpose of the Study:

• To review growth patterns in pediatric recipients of kidney, liver, heart, lung, and small bowel transplants.
• To identify key factors affecting post-transplant growth and discuss strategies to optimize final adult height.

Main Methods:

• Literature review and synthesis of factors impacting growth in pediatric solid organ transplant recipients.
• Analysis of the role of age, graft function, and immunosuppressive therapies (specifically steroids) on growth outcomes.

Main Results:

• Younger recipients show greater immediate catch-up growth.
• Graft function is critical; reduced glomerular filtration rate and re-transplantation correlate with impaired growth.
• Steroid modification/avoidance strategies impact rejection rates but can lead to normal growth velocity, especially in infant heart transplants.

Conclusions:

• Optimizing final adult height is an increasingly important quality of life issue in pediatric organ transplantation.
• With improved survival rates, attention should focus on achieving normal growth and adult height.
• Normal growth following solid organ transplantation is generally an achievable goal.
