Hypogammaglobulinaemia during pregnancy in identical twin sisters

Intravenous immunoglobulin replacement therapy for common variable immunodeficiency during pregnancy

Patients with common variable immunodeficiency (CVID), characterized by impaired antibody production, have a high susceptibility to bacterial infections and need supplements of immunoglobulin G (IgG). We report two pregnancies in a woman with CVID. Differences in the outcome of the two pregnancies suggest the need for adjustment of replacement therapy during pregnancy.

IgG replacement therapy for primary hypogammaglobulinaemia during pregnancy: report of 9 pregnancies in 4 patients

We report the cases of four pregnant women with primary hypogammaglobulinaemia, who received intramuscular, intravenous or no replacement therapy with IgG in late pregnancy, and review the literature. Intravenous replacement administered to the mother during pregnancy produces adequate serum IgG levels in the neonate, and should be the treatment of choice in this situation.
