title: Increased numbers of suppressor-cytotoxic cells in a patient with carbamazepine hypersensitivity.
abstract: A patient is presented with a clinical syndrome of erythroderma, fever, liver function abnormalities, eosinophilia and atypical lymphocytosis due to carbamazepine hypersensitivity. Immunological analysis of peripheral blood mononuclear cells was performed using mouse monoclonal antibodies against T-cell and Ia antigens. A 12-fold increase in the absolute numbers of suppressor-cytotoxic T-cells was found, resulting in a reversed helper/suppressor ratio. Also the number of Ia-positive cells was greatly increased. Carbamazepine may induce a reversible proliferation and activation of the suppressor-cytotoxic subset of T-cells. Implications and pathogenetic possibilities are briefly discussed.
