IgE was isolated from a patient with the hyper IgE, recurrent infection syndrome by immunoadsorption on sepharose bound goat anti-human IgE. Addition of this IgE to a monolayer culture of human monocytes resulted in a dose-dependent increase in PGE2 secretion. The addition of F(ab')2 fraction of goat anti-human IgE in the presence of sub-stimulating doses of IgE markedly increased PGE2 secretio...
Understanding how class switch recombination (CSR) is regulated to produce immunoglobulin E (IgE) has become fundamental because of the dramatic increase in the prevalence of IgE-mediated hypersensitivity reactions. CSR requires the induction of the enzyme AICDA in B cells. Mutations in AICDA have been linked to Hyper-IgM syndrome (HIGM2), which shows absence of switching to IgE as well as to I...
Background The measurement of total serum IgE is made in some cases to investigate if there is the occurrence of allergic processes. However, does not identify specific antibodies. When it is high may indicate an allergic process, or the ability to initiate some. However, increased IgE levels may also indicate other problems such as parasitic diseases, IgE myeloma, hyper-IgE syndrome and some s...
BACKGROUND Olmsted syndrome is a rare congenital skin disorder presenting with periorifical hyperkeratotic lesions and mutilating palmoplantar keratoderma, which is often associated with infections of the keratotic area. A recent study identified de novo mutations causing constitutive activation of TRPV3 as a cause of the keratotic manifestations of Olmsted syndrome. METHODS Genetic, clinical...
BACKGROUND Atopic eczema is a common childhood disease associated with high IgE and eosinophilia. We characterized the clinical features associated with hyper-IgE (defined as IgE > 2000 IU/L) in eczema. METHODS Nottingham Eczema Severity Score (NESS), family and personal history of atopy, skin prick test (SPT) for common food and aeroallergens, highest serum IgE ever and eosinophil counts wer...
