This Guideline replaces the Note for Guidance on " Allergen products " (CPMP/BWP/243/96). This Guideline lays down the quality recommendations for allergen products of biological origin, including allergen extracts derived from natural source material and allergens produced through recombinant DNA technology, used for specific immunotherapy (SIT) or in vivo diagnosis of immunoglobulin E (IgE)-m...

the aim of the present study was to characterize allergen-specific immunoglobulin e (ige) among children in fez region. eighty one children were recruited from the hospital university center of fez. all of them had completed a questionnaire before taking sera. the sera were used to measure total ige and specific data to proteins of egg's white (ewp), peanuts (pp) and gliadins (g). in last part,...

IgG4 purified from patients undergoing specific allergen immunotherapy inhibits the activities of the serum IgE in in vitro assays and is thought to reduce the symptoms of the disease. However, it is not known whether this is related to an intrinsic property of this subclass or only the allergen specificity. We tested the hypothesis that allergen specificity is the critical determinant for this...

background: melon (cucumis melo) allergy is one of the most common food allergies, characterized by oral allergy syndrome. to date, two allergen molecules, cuc m 1 and cuc m 2, have been fully characterized in melon pulp, but there are few reports about the molecular characteristics of cuc m 3. methods:the cuc m 3 cdna has been characterized by rapid amplification of cdna ends (race), which rev...

background: during the last two decades, significant advances have been made in the fields of lactococcal genetics and protein expression. lactococcus lactis (l. lactis) is an effective vector for protein expression and can be used as an antigen delivery system. hence, l. lactis is an ideal candidate for mucosal immunotherapy. profilin (che a 2), the major allergen in chenopodium album, is one ...

the relationship between mycoplasma pneumoniae (mp) infection and asthma has rarely been explored through examination of airway reactivity. the aim of this study was to determine airway reactivity changes after mp infection in children. first, 106 children were divided into four groups according to the existence of mp infection and/or asthma. then children with only mp belonged to the mp group;...

During the past 20 years, major advances have been made in understanding the molecular and cellular mechanisms of allergen tolerance in humans. The demonstration of T cell tolerance, particularly that mediated by the immune-suppressive functions of IL-10, led to a major conceptual change in this area. Currently, the known essential components of allergen tolerance include the induction of aller...

Allergen immunotherapy is performed with allergenic products derived from a wide variety of sources in differing formulations, dilutions, and expressed potencies. The use of standardized allergen products is leading to more uniform potency designations with these products, but only a few products have been standardized. Increased information regarding allergen crossreactivity and the stability ...

Allergen immunotherapy plays an important role in the treatment of allergic diseases and asthma. This article is a brief review of the current approaches, including patient and allergen selection, routes of administration, and use of standardized allergen vaccines. New approaches offering potentially useful strategies based on recent studies of T-cell epitopes, cytokines, and anti-IgE and DNA v...

Background and aim: Eczema is a common inflammatory skin disease. Although history and physical examination are important in diagnosis of allergen, because of extent of environmental allergens, those are not simply recognized. The objective of this study was to determine allergens in patients with contact or atopic dermatitis referred to Razi hospital.Materials and Meth...
