Abstract
|
|
|
|
We experienced a rare case of a 6-year-old boy who was suspected of having lipid transfer protein (LTP) syndrome; the patient was diagnosed with LTP syndrome using the ImmunoCAP/ImmunoCAP Immuno Solid-phase Allergen Chip (ISAC) test. LTP syndrome affects patients who are already sensitized to pollens with signs and symptoms of allergic rhinitis with or without bronchial asthma. Its severity is closely associated with the geographical location as well as the level, nature, and duration of the allergen exposure in a susceptible individual with or without cofactors, such as exercise, alcohol, chemicals, or nonsteroidal anti-inflammatory drug. Patients with LTP syndrome may present with diverse manifestations ranging from local symptoms, such as mild contact urticaria, oral allergy syndrome, or gastrointestinal problems, to anaphylaxis and even anaphylactic shock. Our case highlights the usefulness of the ImmunoCAP/ImmunoCAP ISAC test in establishing a diagnosis of LTP syndrome.
