Cytokine and chemokine dysregulation in hyper-IgE syndrome.

Hyper-IgE syndrome is characterized by severe recurrent staphylococcal infections, eczema, bone abnormalities, and markedly elevated levels of immunoglobulin E (IgE). The genetic basis is not known and the central immunologic defect is largely undefined. Reduced neutrophil chemotaxis is often described, and variable T cell defects have been demonstrated in some patients. It has been hypothesized that hyper-IgE is associated with a Th1/Th2 imbalance. We wished to characterize cytokine and chemokine imbalances that might reflect the underlying disease process or reflect ongoing pathologic processes. Nine patients with hyper-IgE syndrome and six controls were studied. Radioimmunoassays, flow cytometry, and gene array analyses were performed to characterize cytokine and chemokine production. Hyper-IgE patients express more IL-12, while ENA-78, MCP-3, and eotaxin are markedly underexpressed. Underexpression of a set of chemokines could explain a number of features of hyper-IgE syndrome and may offer a new paradigm for the understanding of this disorder.[1]
