title: Immunosuppressive factors detected during convalescence in a patient with severe serum sickness induced by carbamazepine.
abstract: We report on a patient with severe serum sickness induced by carbamazepine in whom anticarbamazepine IgG antibodies were detected in the serum. The T cells of the patient showed impairment of phytohemagglutinin-induced proliferation, and hypergammaglobulinemia was evident. The clinical features and immunological abnormalities were compatible with immunoblastic lymphadenopathy. Immunosuppressive factors were also detected in the patient. Their molecular weights ranged from 20,000 to 30,000 as evaluated by Sephadex G-200 gel filtration. Such immunosuppressive cytokines were not detected in other patients with carbamazepine allergy who did not develop the clinical manifestations of immunoblastic lymphadenopathy. These results suggest that the T cell functional deficiency of immunoblastic lymphadenopathy is induced by these immunosuppressive cytokines.
