title: Immunoglobulin substitution therapy in a patient with primary hypogammaglobulinaemia and anti-IgA antibodies.
abstract: Permanent immunoglobulin substitution therapy was performed in a 44-year-old patient with common variable immunodeficiency, recurrent respiratory tract infections, total absence of serum IgA and a high titre of class-specific anti-IgA antibodies. An IgA-depleted i.v. immunoglobulin (IG) preparation was used. Infusions were well tolerated by the patient although minor anaphylactoid symptoms regularly occurred. Anti-IgA antibody titres rose during the first 4 months of treatment and gradually fell during the following 8 months. Regular IG substitution therapy led to a substantial improvement in the patient's health and quality of life.
