Emerging Paradigm of Primary Immunodeficiency Disease: Individualizing Immunoglobulin Dose and Delivery to Enhance Outcomes
J Clin Immunol
An emerging paradigm for the treatment of primary immunodeficiency disease (PIDD) with immunoglobulin (IgG) replacement therapy emphasizes the tailoring of treatments to each patient with the goal of preventing infections and minimizing side effects. Increasing evidence shows that the IgG dose needed to prevent infection varies with each patient, and both intravenous immunoglobulin (IGIV) and subcutaneous immunoglobulin (IGSC) have emerged as feasible modes of delivery. Although IGIV is currently the routine treatment, IGSC is increasingly being chosen as the preferred route of delivery due to greater flexibility and reduced side effects.
