BACKGROUND A study was undertaken to validate a locus modulating total serum IgE levels on 14q13-24. METHODS A linkage and association study was performed between total serum IgE and a panel of seven microsatellites which map to the 14q13-24 region in 69 families with asthma recruited from Leeds, UK. RESULTS Non-parametric, multipoint, sib pair analysis showed no evidence of genetic linkage...

Background Skin prick tests (SPTs) has relatively a good correlation with allergen-specific IgE against house dust mites (HDM) and pollens, whereas their correlation to fungi remains low. We aimed to investigate the correlation between results of serum specific IgE and SPTs for HDM or fungi in patients with chronic lower respiratory symptoms. The clinical difference between serum fungus or HDM-...

Background Hyperimmunoglobulin E syndrome (HIES) is a rare desease caused by a primary complex immunodeficiency, with IgE serum levels over 2,000U/mL. The syndrome is characterized by the following triad: 1) recurrent staphylococcal abscesses, 2) recurrent airway infections; 3) elevated serum IgE concentration. Our pacient presented signs that are compatible with HIES in distinct moments of his...

Allergic diseases affect approximately one-quarter to one-half of the average population under 50 years age in Central Europe. Due high proportion affected individuals, allergy testing needs be performed on a large scale, with sensitivity and specificity at low cost. Skin tests are most important diagnostic measure fulfilling these requirements: they can immediately and, quite contrast laborato...

Lithospermum erythrorhizon (L. erythrorhizon) root is used in traditional medicine for its anti-inflammatory, antibacterial, and antioxidant properties. However, no studies have examined impact on allergic rhinitis (AR). Here, we explored the protective effects of L. immunoglobulin E (IgE)-stimulated RBL-2H3 cells an ovalbumin (OVA)-induced AR mouse model. In latter, nasal mucosal inflammation,...

BACKGROUND Previous studies have reported a higher prevalence of immunoglobulin E (IgE) specific for staphylococcal superantigens (SAg) in the nasal mucosa of patients with aspirin-exacerbated respiratory disease (AERD), associated with eosinophilic inflammation and leukotriene production. However, the role of SAg-specific IgE in the pathogenesis of AERD is not well understood. We evaluated the...

One hundred nineteen sera from patients with various lymphoproliferative diseases and normal sera were tested by a solid-phase radioimmunoassay (RIA) for their content in IgE-binding factor (IgE-BF), a soluble glycoprotein binding to IgE and derived from low-affinity IgE receptors (Fc epsilon R). Fc epsilon R, recently identified as CD23, are known to be expressed on the surface of B cells at t...

UNLABELLED Infections and malnutrition remain the main causes of infant mortality in developing countries. In protein-calorie malnutrition, immunologic responses are affected, which often facilitates infections. However, the presence of asthma and allergic rhinitis are not commonly recognized in malnourished individuals. The aim of this study was to evaluate serum IgE values in children with pr...

Wood, C. B. S., and Oliver, J. (1972). Archives of Disease in Childhood, 47, 890. Serum IgE in asthmatic children: relation to age, sex, eczema, and skin sensitivity tests. A simple method was used to detect raised serum concentrations of IgE immunoglobulin in 237 asthmatic children. The lower limit of sensitivity of the method was 900 units/ml. 49% of the children were found to have concentrat...
