CD14 is part of the receptor complex for endotoxin, which is a component of tobacco smoke. The CD14 gene is located on chromosome 5q, a region previously demonstrated to be linked to asthma when stratified for smoke exposure. This study was designed to extend these findings by determining whether polymorphisms in the CD14 gene are related to this gene–environment interaction on asthma. Puerto Rican (n = 362 trios) and Mexican (n = 259 trios) families ascertained through a child with asthma were studied. (more…)

Avoidance of any one of the individual risk factors associated with childhood asthma has not been successful in preventing its development. The purpose of this study was to determine the effectiveness of a multifaceted intervention programme for the primary prevention of asthma in high-risk infants at 7 years of age. Five hundred and forty-five high-risk infants with an immediate family history of asthma and allergies were prospectively randomized into intervention and control groups pre-natally. (more…)

Diagnosis of food hypersensitivity is a clinical challenge and the only current definitive test is the Double Blind Placebo-Controlled Food Challenges. Although the Double Blind Placebo-Controlled Food Challenges is the current gold standard, it is difficult to perform and is very time-consuming. Hence, researchers are continually evaluating new tests and assessing the value of the available serum tests. (more…)

Over the last 5 years some studies have suggested that the atopy patch test (APT) may be a useful test in atopic dermatitis children who have suspected food hypersensitivity and may even obviate the need for oral challenges. An alternative test to oral allergy challenges with high sensitivity and specificity would be helpful in the diagnosis of food hypersensitivity. (more…)

This population-based cross-sectional study, funded by a UK government agency, aimed to establish the rate of sensitization to food allergens, reported food hypersensitivity, food avoidance and objectively assessed food hypersensitivity in 11- and 15-year-olds living on the Isle of Wight, UK. The researchers approached the teenagers via their schools, and a questionnaire completed by the parents and children formed the basis of capturing data to determine the prevalence of current reported food hypersensitivity and rates of food avoidance. This information was available on 775 individuals aged 11 years and 757 aged 15 years. (more…)

This study compared the diagnostic value of intradermal tests and patch tests in 20 patients with non-immediate reactions to penicillin (none had IgE antibodies to benzylpenicillin or amoxicillin detectable using a commercial RAST [radioallergosorbent test] method), using 30 patients tolerant to penicillin as controls. Intradermal tests assessed reactivity to injection of major and minor determinants of benzylpenicillin, amoxicillin and ampicillin. Allergy patch testing involved the same hapten solutions used for intradermal testing, either embedded in a patch disk or mixed with petrolatum. (more…)

Being an immunological disease, the characteristics of allergy are those of specificity and memory. Regardless of whether the clinical manifestation is rhinoconjunctivitis, rhinitis, or asthma, the underlying immunological response disorder is based on the adverse reactions of cells in the immune system upon contact with allergens. These cells are specific for epitopes that are structural parts of allergens present in the allergenic source material. Two types of cells (i.e., T cells and B-cells) produce receptor molecules (i.e., T-cell receptors and immunoglobulin [IgE] antibodies) that, through high-affinity interactions with the allergen, efficiently catalyze the presence of even minute amounts of allergens into clinical symptoms, the extreme consequence of which may be life-threatening to the patient.

Systemic allergic reactions are a relatively common clinical emergency. In their mildest form, they may just manifest as systemic cutaneous reactions with pruritis, allergy urticaria and angioedema. In more severe cases there are cardiorespiratory symptoms such as stridor, wheeze, difficulty in breathing or hypotension. Anaphylaxis has been defined as a ‘severe, life-threatening generalized or systemic hypersensitivity reaction’. The prevalence of systemic allergic reactions is unclear because of the lack of a clear, consistent definition and large prospective population studies. (more…)

Food allergies represent a hard challenge to maintain weight loss in when you are frequently eating out in restaurant. Last summer I had a severe reaction to peanuts. Then after allergy tests, I discovered that I am allergic to peanuts, nuts, eggs, fish and seafood. Since then doctor told me that I can eat eggs and seafood in moderate proportions, but I m still allergic to peanuts and nuts. This is what a very pleasant experience is normally now turns in a very stressful experience. I was managing to alleviate this tension by adopting a few basic principles like bellow. (more…)

At least a million Spanish suffer allergic reactions to food, some of them as common as milk, eggs, fruit or fish. Many of them are children who are constrained in their quality of life and opportunities to participate in activities as usual for other children and enjoy a family meal, eating at school, have a pizza or a bagel or even attend a children’s party. An accidental ingestion of a food to which you are allergic (which happens often due to lack of identification of many food allergy ingredients) can have serious consequences, from allergic urticaria to anaphylaxis symptoms.
