Hyper IgE Syndromes (HIES) are rare forms of primary immunodeficiencies (PI) characterized by recurrent eczema, skin abscesses, lung infections, eosinophilia (high numbers of eosinophils in the blood), and high serum levels of immunoglobulin E (IgE). Although initially described as two forms, with autosomal dominant and autosomal recessive The lack of these other immunoglobulins makes people with hyper-IgM syndrome less able to fight off infection. Hyper-IgM syndrome is a primary immunodeficiency disorder Primary immunodeficiency Immunodeficiency disorders involve malfunction of the immune system, resulting in infections that develop and recur more frequently, are more severe Hyper-IgE syndrome is a hereditary immunodeficiency disorder characterized by recurring boils, sinus and lung infections, and a severe rash that appear during infancy. Levels of immunoglobulin E (IgE) are very high. In infants with hyper-IgE syndrome, abscesses form in the skin, joints, lungs, or other organs. These three forms of the syndrome are characterized by a complete lack of Ig somatic hypermutation (SHM) and class switch recombination (CSR). Other HIGM conditions are caused by mutations of uracil DNA glycosylase (Ung) or associated with ectodermal dysplasia due to mutations in the X-linked nuclear factor κB essential modulator (NEMO) . X-Linked Hyper IgM Syndrome (X-HIGM) patients have mutations that results in either zero expression of the CD40L protein on the surface of T-cells or no binding between that protein to the CD40 protein on B-cells. This results in lack of class-switching of the antibodies from IgM to IgG, IgA or IgE. Essentially, X-HIGM patients cannot produce The original hyper-IgE syndrome is characterized by diminished inflammatory response, in combination with Staphylococcus aureus skin abscess and pneumonia followed by pneumatocele formation. These immunological manifestations are frequently associated with skeletal and connective tissue abnormalities.
