Abstract

STAT3 hyper-IgE syndrome (STAT3-HIES) patients presented with significantly lower Staphylococcus aureus-specific serum IgG compared to cystic fibrosis patients despite recurrent S. aureus infections. Immunoglobulin replacement therapy increased S. aureus-specific IgG in STAT3-HIES patients and attenuated the clinical course of disease suggesting a role of humoral immunity in S. aureus clearance.
