Abstract

The immunomodulating chemotherapeutic drugs rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) have the ablity to pass the placenta during pregnancy and might affect the development of the immune system of exposed infants. In particular rituximab causes a transient and almost complete depletion of CD20 expressing B cells and can remain detectable in the infant several months after birth.

In this case series we report on the clinical and immunological outcomes of 3 infants exposed to R-CHOP during pregnancy because of maternal B-cell lymphoma and review other cases that have been published. We show that R-CHOP in pregnancy has a profound effect on the immune system in the first year of life, including B-cell lymphopenia, hypogammaglobinemia, neutropenia and decreased response to immunization. Immune monitoring of exposed infants is warranted.
