— The lymphocytes in peripheral blood and cerebrospinal fluid of patients with chronic progressive multiple sclerosis (MS) were characterized with monoclonal antibodies to surface antigens of T cells, helper/inducer T cells and suppressor/cytotoxic T cells. The influence of cyclophosphamide treatment on these immune parameters was investigated. Compared to healthy persons, the mononuclear cell fraction of the peripheral blood of patients with chronic progressive MS consisted of normal %s of T cells and helper/inducer T cells, but decreased %s of suppressor/cytotoxic T lymphocytes. Intensive as well as chronic treatment of MS patients with cyclophosphamide resulted in a decline in the %s of T cells and helper/inducer T cells, whereas the %s of suppressor/cytotoxic T cells returned to normal. In cerebrospinal fluid, cyclophosphamide also induced a relative decrease in the % of helper/inducer T cells and an increase in the % of suppressor/cytotoxic T cells compared to untreated MS patients. Intensive as well as chronic therapy with cyclophosphamide both led to a significant decrease in the absolute number of T cells and T cell subsets in the blood of the patients.
