Researchers think the hallmark time-delayed reaction of alpha-gal syndrome is due to the alpha-gal molecules taking longer than other allergens to be digested and enter your circulatory system. More research is needed to understand the connection between ticks that carry alpha-gal in certain regions and cases of alpha-gal syndrome that don't seem directly linked to tick bites. Cetuximab-induced cases of this condition are most common in regions with a high population of Lone Star ticks, suggesting a possible link between Lone Star tick bites and an increased vulnerability to alpha-gal syndrome. People with antibodies related to alpha-gal syndrome can have allergic reactions to the cancer drug cetuximab (Erbitux). People who are exposed to many tick bites over time may develop more-severe symptoms. When a carrier tick bites a human, the tick injects alpha-gal into the person's body.įor unknown reasons, some people have such a strong immune response to these molecules that they can no longer eat red meat or products made from mammals without a mild to severe allergic reaction. Ticks that cause alpha-gal syndrome are believed to carry alpha-gal molecules from the blood of the animals they commonly bite, such as cows and sheep. Bites from other types of ticks can lead to the condition in the U.S., Europe, Australia and Asia.

Don't rule out red meat as a possible cause of your reaction, especially if you live or spend time outdoors in the southeastern United States or in other parts of the world where alpha-gal syndrome is known to occur. See your primary care doctor or a doctor who specializes in the diagnosis and treatment of allergies (allergist) if you experience food allergy symptoms after eating - even several hours after eating. A possible connection between a T-bone steak with dinner and hives at midnight was far from obvious. A severe, potentially deadly allergic reaction that restricts breathing(anaphylaxis)ĭoctors think the time delay between eating red meat and developing an allergic reaction is one reason the condition was overlooked until recently.
