The relationship between sensitization to common allergens and the development of asthma and seasonal allergic rhinitis (SAR) was investigated in a total of 419 schoolchildren in a farming community where allergens of both Dermatophagoides farinae (Df) and orchard grass (OG) pollen predominate.
Specific immunotherapy with unmodified formalinized allergoids is effective in grass-pollen allergy, but systemic reactions have been observed. A high-molecular-weight formalinized allergoid (HMW-GOID) was fractionated by gel filtration, retaining molecules of greater than 85,000 daltons in the
Allergic asthma is a multifactorial disease involving well known environmental factors and less identified genetic components. In several studies the HLA genes have been implicated in the development of asthma and atopy, but the importance of these associations remains unclear. The aim of the
This work describes three patients suffering from bronchial asthma after being naturally exposed to airborne plane-tree pollen. The three patients gave immediate response in skin tests and dual response in bronchial provocations using Platanus hybrida extract. There was specific seric IgE activity
In patients with respiratory allergy to pollen it is common to correlate the onset, duration and intensity of clinical symptoms with the count of atmospheric allergenic pollen grains. Pollen counts, however, may not reflect the total airborne allergen exposure since previous data suggest that pollen
Experiments are reported for the evaluation of an indirect ELISA using peroxidase conjugate for the detection of IgG antibodies to Dactylis glomerata (DG), a grass pollen antigen frequently responsible for allergic rhinitis and asthma. When optimized, the test proved to be useful in clinical
MAST, which stand for multiple antigen simultaneous test, uses enzyme-linked anti-human IgE and chemiluminogenic substate to determine IgE. This system is characterized by simultaneous analysis of multiple allergen items, up to 35, together with total IgE determination. We evaluated usefulness of
BACKGROUND
Castanea sativa pollen allergy has generally been considered to be uncommon and clinically insignificant. In our geographical area (Plasencia, Cáceres, Spain) Castanea sativa pollen is a major pollen.
OBJECTIVE
To determine the atmospheric fluctuations and prevalence of patients
We have shown previously that female sex is a determinant of cough sensitivity to inhaled capsaicin, but the relationship between atopy and the cough sensitivity has not been examined. The capsaicin cough threshold, defined as the lowest concentration of capsaicin causing five or more coughs,
BACKGROUND
Recent advances in medical care have drastically improved life prognosis of severe life-threatening diseases in newborns and young children. However, 'intact' survival without sequelae for all the children is still to be achieved and prevalence of severe motor and intellectual
Matrix metalloproteinase 9 (MMP9) gene has been shown to be involved in the pathogenesis of allergic rhinitis (AR) and asthma. Previous studies suggested that single-nucleotide polymorphisms (SNPs) of the MMP9 gene conferred a risk for childhood asthma. However, whether the SNPs confer a risk for AR
One hundred and twenty-six allergic subjects were divided into three groups based on the RAST results for Dermatophagoides pteronyssinus (D.p) and Japanese cedar (J.C.). We compared sex, age of examination for RAST, serum IgE, family history of allergic diseases, prevalence rate of bronchial asthma
BACKGROUND
ImmunoCAP® Rapid is a rapid test kit to measure the allergen-specific IgE to the eight major inhalation allergen (cat, mite, orchard grass, ragweed, wormwood, dog, cockroach, Japan cedar).
METHODS
We performed ImmunoCAP® Rapid 83 patients with allergic disease (26 males, 57 females,
Five-year changes in the percentage of positive intradermal test to allergens in patients with bronchial asthma (BA) and allergic rhinitis (AR) over a period of 30 years from 1969 to 1998 were analyzed, with consideration of their association with the yearly changes in the levels of airborne pollens
Seasonal allergic rhinitis (SAR) is an inflammatory disease of the nose and eyes that follows sensitization to air-born pollens. We conducted a genome-wide linkage screening of 48 Japanese families (188 members) with orchard grass (OG)-sensitive SAR children (67 affected sib-pairs) in a farming
