OBJECTIVE Eosinophilia and increased serum IgE levels are indicators of atopy; however, other factors can also play a key role, such as intestinal parasitic infections. This study assesses the relationship between total serum IgE, eosinophil count, and anti-Ascaris IgE in individuals with asthma and/or allergic rhinitis. METHODS A cross-sectional study was carried out in adolescents with asth...

As part of an ongoing project, male Brown Norway rats (67 weeks old) were exposed via the intraperitoneal route to either isolated SLG, semi-skimmed or whole milk (coadministered with carrageenan or alum as IgE-selective adjuvants). Sera isolated at various time points were assa ed for PLG-specific rat IgE, performed using H V an,y/or AChE-based ELISAs. Where necessary, single-tailed paired Stu...

We have generated high titers (up to 1 mg/ml) of antibodies to isotypic determinants of IgE by immunization of A/J mice with syngeneic monoclonal IgE conjugated to keyhole limpet hemocyanin. As much as 3 mg of anti-idiotypic antibodies per ml was induced at the same time. In contrast to conventional rheumatoid factors, the anti-isotypic antibodies are of moderately high affinity (10(7)-10(8) M-...

Recently, we have demonstrated that anti-ulcer drugs, such as H2-receptor blockers and proton pump inhibitors, promote the development of immediate type food allergy toward digestion-labile proteins in mice. The aim of this study was to examine the allergological relevance of these findings in humans. In an observational cohort study, we screened 152 adult patients from a gastroenterological ou...

BACKGROUND Clinically it is recognized that tree nut allergies such as hazelnut allergy are not usually outgrown. Specific mechanisms underlying the persistence of such food allergies are incompletely understood. Here we studied the natural history and the long-term immune and clinical characteristics of hazelnut allergy in an adjuvant-free mouse model. METHODS BALB/c mice were sensitized to ...

BACKGROUND Molecular allergens enable the definition of sensitization profiles in allergic patients. AIM To validate the most helpful allergens for the diagnosis of latex allergy in different clinical situations. METHODS 130 patients suspected to be allergic to latex with positive IgE against natural rubber latex (NRL) have been studied: 97 were confirmed as latex allergic (among which 55 p...

the efficacy of allergen immunotherapy for the treatment of allergic rhinoconjunctivitis with or without seasonal bronchial asthma and anaphylaxis caused by the sting of the hymenoptera class of insects has been clearly demonstrated in numerous well-designed, placebo-controlled trials. immunotherapy whether by subcutaneous injection of allergen extract or by oral/sublingual routes modifies peri...

Abstract Mast cells play a critical role in the effector phase of immediate hypersensitivity and allergic reactions. Propolis exerts multiple biological effects exhibits immunomodulatory antioxidant properties. However, its antidinitrophenyl (DNP) immunoglobulin E (IgE)-activated mast has not been investigated. In this study, we examined mechanism underlying inhibitory effect propolis (Unibee p...
