How might hyper IgM syndrome be treated?

The cornerstone of treatment for individuals with hyper IgM syndrome is regular injections of intravenous immunogloblulin (IVIG). This treatment not only supplies missing IgG antibodies, but also prompts a drop in IgM antibodies.[1][2] Patients with neutropenia can take granulocyte colony-stimulating factor (G-CSF). Antibiotics may also be prescribed to prevent the respiratory infection, pneumocystis carinii pneumonia.[2]

Most children with hyper-IgM syndrome respond well to treatment, become symptom-free and resume normal growth.[1]
