Allergy Immunotherapy with Depigmented Glutaraldehyde-Polymerized Extracts

Allergy Immunotherapy
Allergic rhinitis is a very common problem associated with poor quality of life, reductions in social and work activities and poor interpersonal relationships. The main goal of the management of allergic rhinitis is to improve the quality of life. Immunotherapy is a specific therapy for allergic rhinitis and several reports have documented the safety and efficacy of this treatment . Safety has been a key issue in immunotherapy and various modalities are being investigated to make allergy immunotherapy more tolerable and safe to administer. (more…)

A Chimeric Human–Cat Fusion Protein Blocks Cat-Induced Allergy

The specific treatment of allergy has previously relied upon allergen avoidance and sublingual immunotherapy. These approaches have been used predominantly in hymenoptera venom and aero-allergen-driven disease when previous food allergy immunotherapy has been unsuccessful. (more…)

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…)

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…)

Beware of Fatal Immunotherapy Reactions To Allergen Injections And Skin Testing

Allergen Injections
Allergen immunotherapy has proven to be effective in the management of allergic disease and is the only treatment that is able to modify the natural course of the disease. Its wider applicability for the treatment of allergic disease has, in part, been limited by its perceived safety profile. This study follows up previous fatal reaction surveys undertaken in the USA for the periods 1959–1984 and 1985–1989. (more…)

Otitis Media With Effusion: Allergic Inflammation In Middle Ear & Upper Airway

Otitis media with effusion is a chronic inflammatory disease of the middle ear space characterized by the accumulation of fluid. Previous investigations have suggested that the immunopathological mechanism underlying the development of middle ear effusion in allergy patients largely involves the effects of Th2 mediators. The investigators set out to determine whether the middle ear compartment may be a component of the united airways in allergic disease by comparing the inflammatory profiles of the middle ear with those of the upper airway. Middle ear effusions, torus tubaris (Eustachian tube mucosa at the nasopharyngeal orifice) and adenoidal tissue biopsies were obtained from 45 patients undergoing simultaneous tympanostomy tube placement for Otitis media with effusion and adenoidectomy for adenoid hypertrophy.

Mechanisms of Specific Immunotherapy

mechanisms immunotherapy
The precise mechanisms underlying the effects of Specific Immunotherapy are not well understood but several studies have shown that Specific Immunotherapy T inhibits both early and late immune responses to allergen exposure.

Recently, there have been many studies aimed at elucidating the mechanisms by which allergen-specific immunotherapy works. (more…)
