What is horse ATG treatment?
A standard treatment for SAA involves injections of rabbit-antithymocyte globulin (r-ATG). r-ATG is developed by injecting horses with a type of human white blood cells called thymocytes. The horse’s immune system reacts against these cells and makes antibodies that can destroy them.
How long does ATG treatment last?
This allows an aplastic anemia patient’s bone marrow to rebuild its supply of bone marrow stem cells, causing blood counts to go up. Usually, ATG is given by IV infusion into a vein for 8-12 hours a day, for 4 days. The schedule depends on your needs, the type of ATG used and doctor or hospital preference.
What is ATG procedure?
Anti-thymocyte globulin (ATG) is an infusion of horse or rabbit-derived antibodies against human T cells and their precursors (thymocytes), which is used in the prevention and treatment of acute rejection in organ transplantation and therapy of aplastic anemia.
How effective is ATG?
Immunosuppression with anti-thymocyte globulin (ATG) was introduced in 1977. Subsequent trials confirmed the effectiveness of this form of treatment. Overall, between 75% and 80% of the patients achieve remission, defined as freedom from transfusion, following a first course of treatment with ATG.
How do you administer an ATG?
ATG (rabbit) is administered by IV infusion. The manufacturer states that ATG (rabbit) should be infused through an inline 0.22-μm filter into a high-flow vein. Has also been administered via a peripheral vein† in some patients, but safety not fully established and may increase risk of thrombophlebitis and DVT.
What is the life expectancy of someone with aplastic anemia?
What are the survival rates for aplastic anemia? Aplastic anemia is a life-threatening condition with very high death rates (about 70% within 1 year) if untreated. The overall five-year survival rate is about 80% for patients under age 20.
What is ATG made of?
Background. Antithymocyte globulin is a hyperimmune globulin preparation made from plasma of rabbits or horses that have been immunized with human thymocytes or T cells. ATG is given by infusion only and leads to a rapid decrease in circulating T cells.
What is the cost of ATG?
Cost of transplant is about 10-12 lac, whereas cost of ATG and cyclosporine course is about 5-9 lac (lower cost is with Indian brand of ATG). However in an individual patient, decision is not easy, especially if age over 20-30. Patient should be given both options.
How much does Antithymocyte globulin cost?
The costs for basiliximab and antithymocyte globulin were calculated based on average wholesale prices (AWP). The price of basiliximab was $1224 per dose and the price of antithymocyte globulin was $262.24 per 250 mg ampoule [9].
Can ATG be given peripherally?
No phlebitis or symptomatic venous thrombosis occurred in any patients. Conclusions: Equine ATG can be safely administered via peripheral vein infusion. Its use does not require continued hospitalization or placement of a central line. Peripheral vein infusion is safe, convenient, and economical.
Can you live a full life with aplastic anemia?
Aplastic anemia is a life-threatening condition with very high death rates (about 70% within 1 year) if untreated. The overall five-year survival rate is about 80% for patients under age 20. In recent years, the long-term outcomes of aplastic anemia patients have been continuously improving.
Can you be cured from aplastic anemia?
A bone marrow transplant is the only cure for aplastic anemia. Bone marrow transplants are also called stem cell transplants.
Which is the best treatment for horse ATG?
Cyclosporine will also be given to improve the response rate of ATG treatment. Treatment with cyclosporine will start the same day as the h-ATG, either in liquid or capsule form, and continued for 6 months.
Which is better, horse ATG or rabbit ATG?
Immunosuppressive therapy with antithymocyte globulin (ATG) plus cyclosporine is an effective alternative to stem-cell transplantation and improves blood counts and survival. Although horse ATG is the standard therapy, rabbit ATG is more potent in depleting peripheral-blood lymphocytes and is preferred in other clinical circumstances.
How is R-ATG developed in a horse?
r-ATG is developed by injecting horses with a type of human white blood cells called thymocytes. The horse’s immune system reacts against these cells and makes antibodies that can destroy them. These antibodies are collected and purified to make r-ATG.
How long do you take cyclosporine for horse ATG?
After the skin test, h-ATG will be given into a vein continuously over 4 days. Cyclosporine will also be given to improve the response rate of ATG treatment. Treatment with cyclosporine will start the same day as the h-ATG, either in liquid or capsule form, and continued for 6 months.
