[T-rosette test in Wilson's disease].

Twenty-three patients with Wilson's disease were studied. Using the rosette formation test it was found that the count of T-lymphocytes in the peripheral blood of these patients (29,77% +/- 12,58) was lower than in the control group (61,68% +/- 13,14). Using skin tests for demonstration of delayed hypersensitivity it was noted that in the group of patients the frequency of positive reaction with Candida albicans antigen was lower and these patients showed also less frequently positive reactions after DNCB immunization. The obtained results indicate that in Wilson's disease the functions of T-lymphocytes are distrubed. This may be the cause of previously observed hyperactivity of B-lymphocytes.
