Once a CF patient has received a lung transplant, does CF "go away?"
Transplanted lungs come from people who do not have CF, so these "new" lungs do not have CF. However, CF is still in the sinuses, pancreas, intestines, sweat glands, and reproductive tract of the person after the lung transplant. Because of this, the new lungs can become infected with germs that remain in the upper airways.
What happens to the body after transplant?
The immune system protects persons from foreign material, e.g., anything not belonging in the body. This includes germs and transplanted organs. The immune system naturally reacts against - or rejects - the organs. Drugs to stop the immune system from rejecting the organ (e.g., immunosuppressive drugs) must be taken daily, for life. These drugs decrease one's ability to fight infection and may cause side-effects such as diabetes, kidney problems, cancer-like tumors and osteoporosis (e.g., thinning of the bones). The doctor changes the dose of these drugs at different times after the transplant to reduce the chance of rejection and side effects
