[Detection of B-cell marker of rheumatism using monoclonal antibodies D8/17 in families of patients with rheumatism (report 1)].

Results of clinico-genealogical and immunogenetic examination of 220 persons including 150 patients suffering from rheumatism and members of their families have been presented. The object of the examination was a B-cell marker carriership to be determined by means of monoclonic antibodies D8/17 with the use of the microlymphocytotoxic method. The marker carriership was detected in 96 per cent of probands-patients with rheumatism and in 40.3 per cent of their relatives and in 6.7 per cent of healthy individuals of the control group. A possible contribution of the B-cell marker to rheumatism liability was suggested. A further study of the role of the given marker in rheumatism has been found advisable.
