Immunosuppressive medications are drugs that lower the body’s immune system response. In kidney transplant patients, these medications prevent the body from rejecting the transplanted organ. They work by decreasing the activity of the immune system cells that would normally attack the transplanted kidney. Common immunosuppressive medications include tacrolimus, cyclosporine, mycophenolate mofetil, and corticosteroids.

This trial focuses on adjusting the levels of these immunosuppressive medications when transplant patients develop serious complications like septic shock (a severe infection affecting the whole body) or breathing difficulties requiring intensive care. The goal is to find the right balance between preventing organ rejection and allowing the body to fight off serious infections.

Kidney Transplant Rejection – A condition where the recipient’s immune system recognizes the transplanted kidney as foreign and attempts to attack it. The immune response can develop slowly or quickly, causing inflammation and damage to the transplanted organ. The body’s defense mechanisms activate various immune cells that begin to attack the donated kidney tissue. This process can affect the kidney’s ability to filter blood and remove waste products from the body. The rejection process may cause changes in kidney function and structure that can be detected through various medical tests.

Cytomegalovirus (CMV) Infection – A common viral infection that can affect transplant recipients due to immunosuppression. The virus belongs to the herpes family and can remain dormant in the body for long periods. When active, it can cause various symptoms and affect multiple organ systems. The virus can spread through bodily fluids and often becomes more active when the immune system is weakened.

Epstein-Barr Virus (EBV) Infection – A viral infection that commonly affects transplant patients under immunosuppression. The virus primarily targets B lymphocytes and can persist in the body indefinitely. When active in transplant recipients, it can cause various symptoms and complications. The virus spreads through saliva and can remain dormant in the body for extended periods.

BK Virus Infection – A viral infection that particularly affects kidney transplant recipients. The virus typically remains inactive in healthy individuals but can reactivate during periods of immunosuppression. It primarily affects the urinary system and transplanted kidney. The virus can cause inflammation and damage to the kidney tissue when active.
