Investigation of Cell Mediated Immunity in Patients with Behcet's Syndrome, Using the DNCB Sensitization / 대한피부과학회지

Various immunologic investigations of 159 patients with Behqets syndrome undertaken included; the DNCB sensitization test, total T-cells and T-cell subsets and the lymphocyte transformation test using PHA. The percentage of positive esponsiveness to DNCB decreased in the order of possible (65%), suspected (60%), incomplete (37%) and complete type (37%), The number of patients with impaired LTT was larger in the group of patients with DNCB( + ) responsiveness (seventeen of 32) than in DNCB(+) group (six of 25), There was significant impairment of cell mediated immunity in Behcets syndrome compared to normal subjects, when analyzed by the impaired LTT and decreased proportions of helper T-cells.
