Dr. Tina Merritt, allergist and immunologist at Allergy & Asthma Clinic of Northwest Arkansas, was recently featured in Medscape for her pioneering role in the discovery and study of alpha-gal syndrome. In the interview, Dr. Merritt recounts how her work began during her fellowship at the University of Virginia, where researchers were investigating unexpected reactions to the cancer drug cetuximab. That early work, done alongside Dr. Thomas Platts-Mills, eventually led to the development of a diagnostic test for alpha-gal IgE reactivity and the landmark finding that lone star tick bites are the trigger for this unusual food allergy. The connection became personal when Dr. Merritt learned that a beef and pork allergy she had carried since childhood was itself a case of alpha-gal syndrome.
The Medscape interview covers the full scope of Dr. Merritt’s roughly two decades of research, including how clinical understanding of the condition has evolved, why it remains difficult to diagnose, and what factors may influence who develops the allergy after a tick bite. She also addresses an often-overlooked risk: the presence of mammal-derived ingredients in medications, capsules, and vaccines that can trigger reactions in alpha-gal patients. Dr. Merritt co-holds the patent for the IgE reactivity test used to identify the condition, and continues to see and treat alpha-gal patients at her practice in Bentonville.
