Alpha-Gal Syndrome in a Pediatric Patient From Northeast Florida.

Alpha-gal syndrome (AGS) is a rare, tick-borne condition that is characterized by a delayed hypersensitivity reaction to galactose-α-1,3-galactose (alpha-gal), a carbohydrate found in mammalian meat products. AGS is increasingly recognized in adults; however, cases often remain underreported or misdiagnosed in children. We report on a 10-year-old male in Northeast Florida presenting with gastrointestinal symptoms, urticaria, and oropharyngeal itching. These symptoms developed hours after consuming a cheeseburger. His medical history revealed multiple previous Lone Star tick bites. After an alpha-gal IgE panel was performed, the elevated specific IgE levels, in addition to the patient's prior history of tick bites, led to a diagnosis of AGS. The patient was prescribed avoidance of mammalian meat and an epinephrine auto-injector. There is a growing need for correct symptom recognition in pediatric cases, and improved clinical recognition may facilitate earlier diagnosis in pediatric patients. Florida's warm climate and abundant wooded and marshy areas support tick activity. Unlike typical IgE-presenting allergens, AGS reactions may occur hours after ingestion, leading to cases remaining underreported or misdiagnosed. Repeated exposures can lead to more severe symptoms, emphasizing the need for early diagnosis. With very limited surveillance, the true prevalence and incidence of AGS in Florida are unknown due to underreporting, and this case report sheds light on the clinical presentation of a pediatric AGS case in Northeast Florida.

Mammalian meat allergy emerges after tick bite: the alpha-gal syndrome.

Alpha-gal syndrome (AGS) is a hypersensitivity reaction to mammalian meat that develops after tick bite exposure. AGS was first described in 2009 and testing for the allergy has become available in the last decade. We report the case of a 56-year-old farmer with a history of frequent lone star tick bites who presented with a 7-year history of diffuse urticaria occurring hours after eating red meat. AGS is likely underdiagnosed because of the unusual presentation of the allergy, historic lack of available testing, and deficiency of physician knowledge about the condition. Recognition of AGS is important both to help alleviate symptom burden and to avoid iatrogenesis. Patients with AGS should not receive products containing mammalian products, such as cat-gut suture, porcine-derived heart valves, and bovine-derived vaccines. Patients with AGS may present in a variety of clinical environments and physicians of all kinds should be able to recognise the symptoms.
