Abstract

Allergen specific immunotherapy (ASIT) and environmental control are the only etiologic treatments of allergic rhino-conjunctivitis, asthma and atopic dermatitis. The clinical benefit of ASIT relies on the selection of the patients and the identification and administration of the allergen, or allergens. Different routes of administration have been investigated, including subcutaneous, intradermal, epicutaneous, sublingual, inhaled, or intra-lymphatic. While subcutaneous and sublingual allergen specific immunotherapy may require from 3 to 5 years of treatment, clinical efficacy with intra-lymphatic treatment can be achieved after 3 injections. The most severe side effect of ASIT is anaphylaxis. Novel approaches are being investigated to reduce the allergenicity of immunotherapy vaccines, maintaining immunogenicity. Peptide immunotherapy has been directed mostly against autoimmune diseases, but the use of synthetic peptides for ASIT is a promising field in basic science, applied immunology and in clinical development. Short synthetic peptides bear allergen-specific CD4 T-cell epitopes which induce tolerance by stimulating regulatory (Treg) and Th1 cells. In the present patent review, we describe new trends in allergen immunothera...Continue Reading

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. Discover the latest research on atopic dermatitis here.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergies & Environmental Factors

Environmental factors are strongly associated with the prevalence of allergies and are an increasing health concern worldwide. Discover the latest research on Allergies and Environmental Factors here.

Anaphylaxis

Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
