Abstract
INTRODUCTION: Anaphylaxis to jackfruit (Artocarpus heterophyllus) is rare. Two previously reported cases have been published in two healthcare workers from jackfruit endemic regions. Latex allergy and birch pollen cross reactivity have both been associated with jackfruit anaphylaxis, providing two separate mechanisms of sensitization. We present a case of jackfruit anaphylaxis in a young latex allergic non-healthcare worker in a non-endemic region. CASE REPORT: A 21-year-old male had an anaphylactic reaction immediately after ingesting dried jackfruit. He had a history of allergic rhinitis and latex allergy. He was born premature and required neonatal intensive care and multiple surgeries in infancy, which could possibly be the source of his latex sensitization. Skin prick testing was positive for jackfruit and latex. DISCUSSION: Jackfruit anaphylaxis has only been described in conjunction with a latex allergy or a birch pollen allergy. As jackfruit becomes more available across the world, it is important for physicians and patients with these sensitivities to be aware of these possible cross reactions. Fruit sensitivities in latex allergic patients have been well established as Latex-fruit syndrome. Our case highlights the association of latex sensitization and jackfruit anaphylaxis. CONCLUSION: We present a case of Jackfruit anaphylaxis associated with latex allergy in a non-healthcare worker from Midwestern United States. As jackfruit becomes more popular in non-endemic regions, its possible cross reactivity with latex, as well as birch pollen should be recognized.
