Immunological monitoring during chemotherapy for advanced Hodgkin's disease.

A study of some immunologic in vitro and in vivo changes during the course of chemotherapy in 17 cases of advanced Hodgkin's disease was made. Skin testing with PPD, candida albicans and streptodornase antigens was studied together with studies of B and T cell numbers in the blood and responses to migration inhibition testing for PPD and PHA. An excellent correlation was found between recovery of normal immunologic responses and clinical remission despite the use of immunosuppressive chemotherapy.
