Lone star tick bites are likely the cause of thousands of cases of severe red meat allergies that are plaguing patients in Southeastern states including Tennessee, North Carolina and Virginia and spreading up the Eastern Seaboard along with the deer population.
Vanderbilt's Asthma, Sinus and Allergy Program (A.S.A.P.) clinic is seeing one or more new cases each week of patients allergic to the alpha-gal sugar present in red meat, according to Robert Valet, M.D., assistant professor of Medicine.
"It is not completely understood exactly how the allergy starts," Valet said. "The thought is that the tick has the alpha-gal sugar in its gut and introduces it as part of the allergic bite and that causes the production of the allergy antibody that then cross-reacts to the meat," he said.
Valet said the allergy can cause hives and swelling, as well as broader symptoms of anaphylaxis including vomiting, diarrhea, trouble breathing, and a drop in blood pressure.
