Past, present, and future of allergen immunotherapy vaccines.

Allergen-specific immunotherapy (AIT) is an allergen-specific form of treatment for patients suffering from immunoglobulin E (IgE)-associated allergy; the most common and important immunologically mediated hypersensitivity disease. AIT is based on the administration of the disease-causing allergen with the goal to induce a protective immunity consisting of allergen-specific blocking IgG antibodies and alterations of the cellular immune response so that the patient can tolerate allergen contact. Major advantages of AIT over all other existing treatments for allergy are that AIT induces a long-lasting protection and prevents the progression of disease to severe manifestations.

Expression and characterization of recombinant Par j 1 and Par j 2 resembling the allergenic epitopes of Parietaria judaica pollen.

The weed wall pellitory, Parietaria judaica, is one the most important pollen allergen sources in the Mediterranean area causing severe symptoms of hay fever and asthma in allergic patients. We report the expression of the major Parietaria allergens, Par j 1 and Par j 2 which belong to the family of lipid transfer proteins, in insect cells. According to circular dichroism analysis and gel filtration, the purified allergens represented folded and monomeric proteins.

Evaluation of treatment satisfaction in children with allergic disease treated with an antihistamine: an international, non-interventional, retrospective study.

Background And Objectives: Histamine H(1)-receptor antagonists (antihistamines) have been shown to be efficacious and safe in children and are recommended as first-line treatment for the symptoms of allergic rhinitis and urticaria. No published study to date has directly compared satisfaction with the different antihistamines in children in a real-life clinical setting. This study aimed to investigate parent and physician satisfaction with the efficacy and tolerability of oral antihistamine treatment in children and to compare satisfaction between levocetirizine and the other antihistamines used by children in this cohort.
