[A new immunogenetic marker of rheumatism].

Use of monoclonal D8/17 antiserum was studied for identification of B-cell antigen in 44 rheumatic fever patients. The control group comprised healthy subjects (30) and patients suffering from rheumatoid arthritis (30), ischemic heart disease (IO); chronic tonsillitis (12) and different neoplasma of the brain (10). The preliminary genetic analysis of these patients has shown that monoclonal antiserum D8/17 can identify B-cell marker in 88-100 per cent of rheumatic fever cases.
