Partial and Transient Clinical Response to Omalizumab in IL-21-Induced Low STAT3-Phosphorylation on Hyper-IgE Syndrome.

Hyper-IgE syndrome (HIES) is a rare primary immunodeficiency characterized by elevated levels of immunoglobulin E (IgE), eczematous dermatitis, cold abscesses, and recurrent infections of the lung and skin caused by . The dominant form is characterized by nonimmunologic features including skeletal, connective tissue, and pulmonary abnormalities in addition to recurrent infections and eczema. Omalizumab is a humanized recombinant monoclonal antibody against IgE.

Infectious episodes during pregnancy, at particular mucosal sites, increase specific IgA1 or IgA2 subtype levels in human colostrum.

Background: Colostrum is the primary source of maternal immunoglobulin A (IgA) for the newborn. IgA participates in protection and regulation mechanisms of the immune response at the neonate's mucosa. Several studies have evaluated infectious diseases and vaccine protocols effects during pregnancy on maternal milk IgA levels, with the aim to understand lactation protecting effect on newborn.

In the classification of primary immunodeficiencies, hyper-IgE syndrome, identified with OMIM code # 147060 in the Online Mendelian Inheritance in Man catalog, belongs to the group of syndromes associated with combined immunodeficiencies. It is characterized by elevated levels of IgE, eosinophilia, recurrent skin abscesses, pneumonia, lung parenchyma lesions, recurrent infections, rashes in newborns, eczema, sinusitis, otitis, and mucocutaneous candidiasis. Hyper-IgE syndrome can be transmitted by autosomal dominant or autosomal recessive modes of inheritance.

Somatic mosaicism in B cells of a patient with autosomal dominant hyper IgE syndrome.

Hyper IgE syndrome (HIES) is characterized by recurrent skin abscesses, eczema, pneumonia, and high levels of serum IgE. Nonimmunologic manifestations of HIES include a characteristic face, pathologic dentition, scoliosis, bone alterations, hyperextensible joints, and vascular abnormalities. Somatic mosaicism is defined by the presence of two or more populations of cells with different genotypes in one individual.
