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. Patients with neutropenia can take granulocyte colony-stimulating factor (G-CSF). Antibiotics may also be prescribed to prevent the respiratory infection, pneumocystis carinii pneumonia. Most children with hyper-IgM syndrome respond well to treatment, become symptom-free and resume normal growth.
