What is horse ATG?
ATG is a drug made of antibodies that suppress the immune system. It is made by injecting horses with white blood cells from humans, called lymphocytes. By injecting the horses with these human lymphocytes, the horse’s immune system produce antibodies directed against these human lymphocytes.
What is ATG for aplastic anemia?
Anti-Thymocyte Globulin (ATG) ATG is approved in the U.S. to treat acquired aplastic anemia and to reduce the chance of organ rejection after a kidney or other organ transplant. It may also be used to treat MDS or reduce rejection after a bone marrow transplant. In the U.S., it is also sold under the brand name Atgam®.
What is ist in MDS?
Immunosuppressive therapy (IST) has been used in patients with LR-MDS, based on the observation that a subset of these patients develops cytopenias as a consequence of hyperactivated T cells, leading to suppression of hematopoiesis similar to that seen in aplastic anemia.
What is immunotherapy for aplastic anemia?
Immunosuppressive therapy (IST) with antithymocyte globulin (ATG) and cyclosporine A (CsA) is the first-line therapy for acquired aplastic anemia (AA) in those not suitable for bone marrow transplant. Horse ATG (hATG) is preferred for this purpose, but its use is often impeded by shortages and costs.
What is the full form of ATG?
anti-thymocyte globulin
Synonym: | lymphocyte immune globulin |

US brand name: | ATGAM Thymoglobulin |
Abbreviation: | ATG |
What is the success rate of ATG treatment?
Immunosuppressive therapy with antithymocyte globulin (ATG) and cyclosporine is the standard treatment for patients with severe aplastic anemia who do not have a human leukocyte antigen-matched related donor; it leads to a response rate of 60 to 70%.
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.
What is ATG medication?
Introduction. Antithymocyte globulin (ATG) is an antibody preparation derived from rabbits or horses hyperimmunized with human thymocytes, which is used to prevent or treat acute cellular rejection after solid organ transplantation and as a therapy of acute aplastic anemia.
What is azacitidine used to treat?
Azacitidine injection is used to treat patients with French-American-British (FAB) myelodysplastic syndrome subtypes, including refractory anemia or chronic leukemia. Azacitidine belongs to the group of medicines called metabolites. It interferes with the growth of cancer cells, which are eventually destroyed.
Does myelodysplastic syndrome cause immunosuppression?
THE PLACE OF IMMUNOSUPPRESSION IN THE TREATMENT OF MDS About one third of patients had become transfusion independent and enjoyed normal counts for years, but more commonly counts improved but did not revert to normal.
How much does ATG treatment cost?

What does ATG stand for in exercise?
Overview. Comparing ass-to-grass (ATG) and 90 degree or parallel squats is one of the more heavily debated issues in the strength and conditioning industry.
What is the availability heuristic?
The availability heuristic, also known as availability bias, is a mental shortcut that relies on immediate examples that come to a given person’s mind when evaluating a specific topic, concept, method or decision.
Does availability heuristic support Tversky and Kahneman’s findings?
In Tversky and Kahneman’s seminal paper, they include findings from several other studies, which also show support for the availability heuristic. Apart from their findings in the “K” study, they also found:
What are the three types of heuristics?
In their seminal 1974 paper published in Science, Kahneman and Tversky described three important heuristics: (i) the “representativeness heuristic,” (ii) the “availability heuristic,” and (iii) the “anchoring and adjustment heuristic” (Tversky and Kahneman, 2000 ).
Is the ease of recall factor an integral facet of availability heuristic?
Many studies since this criticism of the original availability heuristic model have repeated this initial criticism, that the ease of recall factor became an integral facet of the availability heuristic itself (see Research section).
