Introduction:

Hyper IgE syndrome is a rare primary immunodeficiency of unknown etiology, with multi systemic impact; it is caused by dominant mutations of the gene that codifies the protein transducer of signal and activator of transcription (STAT-3), therefore it determines a deficit in the generation of Th17 cells from T CD4+ cells, and explains the sensitivity of these patients to the infections caused by Stafilococus aureus and Candida albicans.

Objective:

Contribute to the knowledge of this immunodeficiency for its early detection and timely treatment.

Case presentation:

Newborn with wide nasal bridge, hypermovility, eczematose rash since the neonatal period; cutaneous, ear, and pulmonary infections with presence of neumotoceles and mucocutaneous candidiasis. There were detected high concentrations of seric IgE and eosinophilia. The patient was treated with immunomodulators, antihestamines, antimicrobial drugs and vitaminotherapy. It was achieved a clinical improvement.

Conclusions:

Hyper IgE syndrome-AD is a rare primary immunodeficiency characterized by high concentrations of IgE, eosinophilia, cutaneous abscesses, eczemas, chronical mucocutaneous candidiasis and recurrent pulmonary infections, neumatoceles and bronchiectasis; it also presents alterations in the connective, skeletal and vascular tissue. It is required a high level of clinical suspicion and it is important the early care of the infections, which generally present a systemic torpid response. The therapeutic alternatives are directed to prevent a sepsis and to control the symptoms.
