lolium remotum/hypersensitivity

Phytohemagglutinin (PHA)-induced human T cell clones (TCC) derived from conjunctival flogistic tissues of 3 patients with vernal conjunctivitis produced unusually high amounts of interleukin-4 (IL-4) and no, or limited amounts of, gamma-interferon (IFN-gamma). Allergen (Dermatophagoides

BACKGROUND Prevalence of respiratory allergic diseases has increased worldwide. Identification of the aeroallergens involved in allergenic sensitisation is important for diagnosis, treatment and prevention. OBJECTIVE To verify the molecular pattern of sensitisation to aeroallergens in patients with

BACKGROUND The seasonal allergic conjunctivitis is an inflammatory disease of the ocular surface that affects mainly children, with predominance of male sex. It is an immunological disease with a typical reaction of hypersensitivity type 1 (IgE), resulted from several biological reactions

BACKGROUND The prevalence of pollinosis has doubled in the past two decades. Several studies suggest that up to 50% of adult residents of Mexico City can present manifestations of respiratory allergy, and pollens from trees, grasses and weeds are a common cause. To determine the prevalence of their

BACKGROUND Although mustard is frequently consumed in Spain and elsewhere, only isolated case reports of mustard allergy have been reported. No large series of case studies have been published. OBJECTIVE We sought to describe demographic, clinical, and immunologic characteristics of patients with

BACKGROUND Pollinosis, caused by grasses of the Poaceae family, is a problem worldwide. The relative importance of grass groups 1 and 5 major allergens is well established. However, not much is known about the recognition of these allergens by T cells and whether this T-cell reactivity correlates

We studied 500 patients with an average age of 36.25 +/- 14.27 years and did the following tests: Intradermoreaction and prick tests, total IgE by PRIST and specific IgE by RAST. The antigens used for the study were the following: Lolium Perenne, Dermatophagoides pteronyssinus, and house dust. Of de

The presence of IgE antibodies to the allergens rBet v 1 and rBet v 2 was investigated in patients with known sensitization to ryegrass (Lolium perenne) and/or olive (Olea europaea) pollen, by comparing a group of 10 patients who had allergic symptoms after ingestion of fruits (A) with a group of 17

Allergic diseases diagnosis must be based on adequate allergological anamnesis and an immunological sensitization test; the most sensitive and specific is the skin prick test. To determine the frequency of skin reactivity to aeroallergens, by age groups, in patients of the Department of Allergy and

Various works have been published, mainly by Scandinavian authors, in which a partial immunological identity has been found to exist between birch pollen and hazelnut and apple. However, our attention has been particularly drawn to the high proportion of people who are allergic to the apple and

BACKGROUND Cereals are among the major foods that account for food hypersensitivity reactions. Salt-soluble proteins appear to be the most important allergens contributing to the asthmatic response. In contrast, very limited information is available regarding cereal allergens responsible for

We report a first case of occupational allergy to chicory (Cichorium intybus) in a vegetable wholesaler. Symptoms occurred after oral, cutaneous or inhalatory exposure. The patient also reported reactions after ingestion of botanically related endive (Cichorium endivia) and lettuce (Lactuca sativa).

BACKGROUND Exposure to London Plane Tree (Platanus) bioaerosols in Sydney, Australia has been anecdotally linked to respiratory irritation, rhinitis, and conjunctivitis. OBJECTIVE To determine the relationships between Platanus bioaerosol exposure, allergic sensitization, and

BACKGROUND Local allergic rhinitis (LAR) is a phenotype of rhinitis that has been poorly studied in children. It is characterized by the same symptoms of allergic rhinitis but with the absence of markers of systemic atopy. OBJECTIVE To identify children affected by LAR and to analyze the

In recent years, an increase in the prevalence of allergic diseases has been reported, in industrialised countries. It is also a problem in non-industrialised countries, but its extent is less well documented. In this study, inhalant screening allergens (AlaTOP), food screening allergens (FP5E), and
