Answer

Ig replacement is intravenously administered on a regular basis. The half-life of IgG widely varies among patients with common variable immunodeficiency but is usually longer than 18-23 days in healthy individuals. Tailor dose and frequency to the Ig trough levels and to clinical symptoms. Measure serum IgG level before each infusion, and accordingly adjust the dose of IVIG. Maintain trough serum IgG concentrations at 400-500 mg/dL in adults, a value close to the lower limit of normal. For most patients, a dose of 400-600 mg/kg every 3-4 weeks suffices to reduce the frequency of infection. Some patients with chronic lung disease require up to 600-800 mg/kg per month. Once established on a regular regimen, IVIG can be administered at home.

Adverse reactions to IVIG include nonanaphylactic reactions, anaphylactic reactions, transmission of infectious agents, and acute renal failure.
