For a patient with an antibody deficiency, which preparation would you recommend?

• A. Monoclonal antibody.
• B. Specific human immune serum globulin.
• C. Standard human immune serum globulin.
• D. Animal serum antitoxins.

Answer: (C)

In antibody deficiency, you want to restore the broad repertoire of antibodies a person normally has. Standard human immune serum globulin provides a wide, polyclonal mix of IgG from many donors, delivering broad protection against many pathogens. This makes it suitable as lifelong immunoglobulin replacement therapy for conditions like agammaglobulinemia or common variable immunodeficiency, whether given by IV or subcutaneous routes. Monoclonal antibodies target a single antigen, so they don’t replenish the full range of antibodies a deficient patient needs and are used for specific diseases or conditions, not general antibody deficiency. Hyperimmune or specific human immune serum globulins contain high levels of antibodies to particular pathogens, which is useful in certain exposure situations but not for broad, ongoing protection. Animal serum antitoxins pose higher risk of adverse reactions and aren’t appropriate for chronic antibody replacement.
