Allergen-Specific Immunotherapy Mechanisms & The Involvement Of Treg Cells

allergen specific immunotherapy
Allergen-specific immunotherapy is highly effective in the treatment of IgE-mediated allergy diseases such as rhinitis, conjunctivitis, asthma, and venom allergy hypersensitivity. It is the only treatment that leads to lifelong tolerance against previously disease-causing allergens due to restoration of the normal immunity. (more…)

CD14 Tobacco Gene–Environment Interaction Modifies Asthma Severity & Immunoglobulin E Levels

CD14 gene
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…)

The Canadian Childhood Asthma Primary Prevention Study

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…)

Atopy Patch Test Accuracy in Diagnosing Hypersensitivity to Cow’s Milk & Hen’s Egg

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…)

Allergic Reactions To Penicillin and Skin Test Evaluation via Intradermal Injection

Intradermal Injection
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…)

Allergen Vaccine and Allergenic Source of Material

Allergen Vaccine
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.

Allergen Avoidance and Environment Control: Management of Allergy & Asthma

Allergen Avoidance
Asthma and allergic diseases are common in both children and adults. Their development depends on an interaction between asthma genetic and asthma environmental risk factors. Genetic manipulation in multi factorial diseases such as asthma is not feasible in the foreseeable future. However, theoretically, environmental exposures can be controlled in an attempt to stem the rising prevalence of these diseases (primary prevention). Environmental exposures may also influence the frequency of symptoms and the requirement for medication in those with established disease. (more…)

Immunotherapy Safety: Standardized Therapeutic Vaccines For Allergic Diseases

Immunotherapy Safety
The safety of immunotherapy has been a constraint on this form of treatment for allergic disease. Although retrospective survey studies of fatal reactions have been undertaken in North American practices, few European studies have been reported concerning fatal and non-fatal reactions to immunotherapy.

Allergy immunotherapy is stimulation of your immune system along with progressively growing dosages of the elements to that a person is allergic. (more…)

Sublingual Immunotherapy Safety In Children Below The Age Of 5 Years

Sublingual Immunotherapy Children
The increasing prevalence of allergic disease in the Western world has led to the concept of the ‘allergic march’ to describe the evolving spectrum of disease that often begins in childhood. The use of allergen immunotherapy in children has the potential of altering the natural course of allergic disease. However, concerns regarding the safety of using this treatment in children are an obstacle to attenuating the allergic march. The study of Di Rienzo and colleagues reviews the safety of Sublingual Immunotherapy in children between the ages of 3 and 5 years. (more…)

Cow’s Milk Allergy: IgE-Mediated Allergy or Lactose Intolerance?

cow milk allergy

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…)
