Mass General Brigham to study alpha gal on Martha’s Vineyard

Key Points:

• Researchers at Martha’s Vineyard Hospital have launched a pioneering two-year study to track up to 300 residents bitten by lone-star ticks, aiming to understand why some develop alpha-gal syndrome, a potentially deadly allergy to red meat and dairy.
• Alpha-gal syndrome is caused by an immune reaction to a sugar molecule in tick saliva, leading to delayed allergic responses after consuming mammalian meat or dairy; cases have surged on Martha’s Vineyard, with positive test rates rising from 44% in 2022 to nearly 60% in 2023.
• The study will monitor participants’ immune responses and symptoms over time to identify risk factors and disease progression, with hopes of improving diagnosis, prevention, and possibly developing treatments or vaccines.
• Massachusetts has recently made alpha-gal syndrome a reportable condition and taken measures such as extending deer hunting seasons to reduce tick populations, reflecting growing concern over tick-borne illnesses in the region.
• The research is supported by philanthropic funding and involves collaboration among local health officials, who are optimistic that the study will lead to better care and management of alpha-gal syndrome on the island.
