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…)

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 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.

Cow’s milk allergy results when antibodies against milk allergens are produced by the immune system.
Milk allergens are proteins; more than 25 distinct milk proteins have been identified in the various fractions of milk. The fractions include casein, whey, serum, and certain additional ingredients. (more…)

If the breast-fed baby is lactose intolerant (usually a temporary condition following intestinal infection at this age), mothers can continue to breast-feed, or pump their milk and treat it with lactase enzyme, until the baby’s symptoms stop. Details concerning feeding the lactose-intolerant infant are provided. There is no point in mothers’ eliminating milk and milk products from their diet to treat lactose intolerance in the baby, because their breast milk will contain 6 percent lactose (w/v) regardless of whether or not they consume cow’s milk.

Patients (and many doctors) frequently use the term ‘allergy’ when referring to any adverse drug reaction, even one that has no features of an IgE-mediated allergy response. However, IgE-mediated allergy explains only about 10% of all adverse reactions to antigen antibody reactions from antibiotics. Patients who have experienced unexplained symptoms during treatment with two or more antibiotics are often said to have ‘multiple antibiotic allergy’; using this definition, the description can be applied to one patient in every 22.

Gastrointestinal allergy can be classified according to the triggering antigen, the mechanism of immune reaction, or the anatomic site of reaction.
