The immune system is the body's defense to protect it against things that don't naturally belong to it and attack them. These things can include:

  • Viruses
  • Bacteria
  • "Foreign" tissue from someone else like your child's transplanted kidney

After transplant, the Pediatric Kidney Transplant team at Cincinnati Children's Hospital Medical Center will prescribe special immunosuppressant or "anti-rejection" medications for your child to take. Without these drugs to suppress the immune system, it would probably recognize the transplant as being foreign and attack it.

The most important thing that you can do to prevent a rejection episode from occurring is to ensure your child takes his / her medications every day as directed. Sometimes, though, a rejection episode can occur even though you and your child have done everything correctly.
