Contact urticaria to potato was confirmed by skin testing in a 26-year-old male with atopic dermatitis, birch-pollen rhinoconjunctivitis and a history of immediate finger itching upon handling raw potato. The potato peel was non-reactive. The urticarial reactivity to potato could be transferred by
A 19-year-old man exhibited symptoms of immediate urticaria and angioedema related to contact with raw potato. A prick-by-prick test with potato pulp and rub test were positive. Specific IgE to potato was positive (class 2).
BACKGROUND
Potato contains multiple heat-labile proteins which can induce immediate hypersensitivity reactions. Rhino-conjunctivitis, asthma, contact urticaria and protein contact dermatitis have been described in association with potato exposure.
OBJECTIVE
A patient with possible airborne facial
Although potatoes represent a large part of diets worldwide, adverse reactions to them are considered uncommon and usually result from ingestion, mainly in children. In contrast, immediate reactions to contact with raw potato has been reported more frequently in adults, usually in the form of an
BACKGROUND
Peeling of raw potatoes may cause allergic symptoms, such as sneezing, wheezing, and contact urticaria, for adults. For children, potatoes as food may cause various allergic reactions. However, the identity and molecular structure of the putative allergens in potato have remained
Immediate reactions against contact to raw potato has been reported in adults with generally being in the form of an oral contact dermatitis or contact urticaria, but it may also manifest as rhinitis symptoms, wheezing or even anaphylaxis. Cooked or raw potato allergy has been rarely reported in
Allergy to white potato has rarely been described. We report two cases of atopic patients, housewives, in whom peeling raw potatoes precipitated rhinoconjunctivitis and asthmatic attacks, and, in one of them, contact urticaria. Type I hypersensitivity to raw potato antigens was demonstrated by means
OBJECTIVE
Although potato is greatly consumed all over the world, adverse reactions to potato are uncommon. Our aim is to describe the clinical features of potato sensitivity in allergic children.
METHODS
Forty children with sensitivity to potato were followed up in the Pediatric Immunology and
Allergy to potato is uncommon, and even more uncommon is allergy to potato pollen. The occurrence of both phenomena in the same patient made it possible to study cross-reactivity patterns of potato antigens. An 11-year-old girl, exclusively breast-fed for her first 4 months, developed anaphylactic
305 patients suffering from chronic urticaria were tested according to a special program, which combined the common allergologic skin testing with the searching for foci of inflammation. The central part of the diagnosis, however, are oral provocation tests during potato/rice diet with non-steroidal
Contact urticaria appears half an hour after application of allergens on skin area of contact. It is favoured by atopy. Two cases are reported. 16-years-old boy had dermatitis of perioral area, hands and more slightly nape of the neck with urticaria due to local application of potato, carrot and
BACKGROUND
Potato allergy has been described rarely, generally in relation to the Oral Allergy Syndrome (OAS). Adults with seasonal allergic rhinitis have been reported in whom peeling of raw potatoes causes oculonasal symptoms, wheezing, and contact urticaria. Skin testing with fresh fruits and
BACKGROUND
Allergy to heat stable potato proteins can cause severe allergic disease in children.
OBJECTIVE
To study diagnostic criteria for allergy to cooked potatoes and to describe its clinical characteristics and natural history.
METHODS
Thirty-six children, aged 4-36 months, with atopic symptoms
