![]() Scott doesn’t remember being bitten by a tick but went deer hunting the winter before and thinks that is where the bite occurred. She said sometimes health care professionals would look at her “like I am crazy.” Looking back, Scott believes she’s had alpha-gal syndrome for some time because she kept developing rashes, had a swollen belly and other skin sensitivities.ĭoctors originally suspected she had rheumatoid arthritis. Jaclyn Scott has alpha-gal, which causes an allergic reaction to meat and is caused by a tick bite. How AGS is affecting patients in the Springfield area A lab in Lee’s Summit, Missouri, is the nation’s leading provider of the test, she said. Merritt is co-owner of the patent for the alpha-gal test. Platts-Mills also later developed AGS and used his own blood to further his experiments.ĭr. ![]() Platts-Mills figured out the reactions were mostly in the mid-South and figured out they matched the distribution of the Lone Star tick,” Merritt said.Īccording to an article from UVA, Dr. The cancer drug was grown in an animal cell line which added the carbohydrate. ![]() The researchers realized Cetuximab had alpha-gal carbohydrate attached to the monoclonal antibody. Platts-Mills to develop a test,” she said. In 2005, a patient died in Bentonville on the first infusion of Cetuximab. They found four samples were positive for IgE to Cetuximab, the allergy antibody.ĭr. Platts-Mills to develop a test to see why some patients had anaphylaxis on the first infusion of the drug. ImClone, a biopharmaceutical company, and an oncologist at UVA asked Dr. Thomas Platts-Mills, professor of medicine and microbiology and head of the division of allergy and clinical immunology at University of Virginia (UVA). Merritt was training with the man credited with this discovery: Dr. It started in 2001 when Cetuximab, a monoclonal antibody drug to treat cancer, was causing anaphylaxis in a small number of patients.Īt that time, Dr. In the medical field, this is a relatively new diagnosis and many people, sometimes every primary care physicians, aren’t aware of it and don’t know to test for it. “I had one patient who had swelling of her lips for a decade,” said Dr. Bill Micka is an allergist at CoxHealth.īoth physicians say they have had patients come in with chronic gastrointestinal problems or chronic hives. “It is a very odd allergy and that is one of the reasons it took so long to discover it,” Micka said.ĭr. The other significant difference is the allergic reaction is not immediate, like it is with peanuts or shellfish, and usually occurs hours later, said Dr. First, in many food allergies the body reacts to proteins in food, while AGS is a reaction to a sugar molecule, said Mertensmeyer.

Some people are also allergic to dairy.Īnd some people, like Scott, are so allergic that even fumes from meat cooking trigger reactions. Some people get stomach cramps, diarrhea, vomiting. The reactions are not equal across the board. This allergy has been identified around the world so other ticks cause it, too, she said. Tina Merritt, who owns the Allergy & Asthma Clinic of NWA in Bentonville, Arkansas is an expert on alpha-gal syndrome and has the syndrome herself.
