How is transplant rejection treated?
After an organ transplant, you will need to take immunosuppressant (anti-rejection) drugs. These drugs help prevent your immune system from attacking ("rejecting") the donor organ. Typically, they must be taken for the lifetime of your transplanted organ.
What happens immune rejection?
Rejection is caused by the immune system identifying the transplant as foreign, triggering a response that will ultimately destroy the transplanted organ or tissue. Long term survival of the transplant can be maintained by manipulating the immune system to reduce the risk of rejection.
What treatments can be used to prevent tissue rejection?
Preventing RejectionTacrolimus (Prograf) or cyclosporine (Neoral, Gengraf)Prednisone.Mycophenolate (CellCept, Myfortic) or azathioprine (Imuran)Sirolimus (Rapamune)Everolimus (Zortress)
What happens if stem cells are rejected?
If the donor stem cells are not a good match (and sometimes even if they are): The body's immune system can attack the donor stem cells. This is called rejection. The transplanted cells can attack the body's cells.
When a patient starts to have rejection problems with a transplanted organ The problems are usually caused by?
Cell-mediated rejection, which occurs more commonly within the first year after a transplant, is caused by immune cells called T cells attacking the transplant. This type of rejection responds well to treatment with non-specific immunosuppressants such as steroids.
How is acute rejection treated?
Tissue biopsy remains the gold standard for evaluating immunologic graft damage, and the histologic definition of acute rejection has evolved in recent years. Intravenous steroids and T cell depletion remain the standard therapy for T cell-mediated rejection and are effective in reversing most cases.
What are side effects of anti rejection drugs?
Most side effects are dose-related and may decrease or subside as the dose is adjusted:Headache.Nausea.Trembling or shaking of hands.Excessive hair growth.High blood pressure.Swollen or bleeding gums.Increased risk for infections.Abnormal kidney function.
What causes immune rejection?
This is because the person's immune system detects that the antigens on the cells of the organ are different or not "matched." Mismatched organs, or organs that are not matched closely enough, can trigger a blood transfusion reaction or transplant rejection.
What are some complications from an organ transplant or transplant rejection?
Complications After TransplantationRejection.Infections.Cancer.Atherosclerosis.Kidney problems.Gout.Graft-versus-host disease.Osteoporosis.

What are the cons of stem cell research?
Cons of the stem cell therapy include: Adult stem cells are hard to grow for long period in culture. There is still no technology available to generate adult stem cells in large quantities. Stimulated pluripotent cells normally do not have any p method of maintenance and reproducibility.
What are the risks of using stem cells?
The risks to research participants undergoing stem cell transplantation include tumour formation, inappropriate stem cell migration, immune rejection of transplanted stem cells, haemorrhage during neurosurgery and postoperative infection.
Diagnosis
Treatment
- Treatments for primary immunodeficiency involve preventing and treating infections, boosting the immune system, and treating the underlying cause of the immune problem. In some cases, primary immune disorders are linked to a serious illness, such as an autoimmune disorder or cancer, which also needs to be treated.
Clinical Trials
- Explore Mayo Clinic studiestesting new treatments, interventions and tests as a means to prevent, detect, treat or manage this condition.
Coping and Support
- Most people with primary immunodeficiency can go to school and work like everyone else. Still, you might feel as if no one understands what it's like to live with the constant threat of infections. Talking to someone who faces similar challenges may help. Ask your doctor if there are support groups in the area for people with primary immunodeficiency or for parents of children with the disease. The Immune Deficiency Foundation has a peer su…
Preparing For Your Appointment
- You'll likely start by seeing your family doctor or primary doctor. You might then be referred to a doctor who specializes in disorders of the immune system (immunologist). Here's some information to help you get ready for your appointment.
