Detection of anti-histone activity in sera of patients with monoclonal gammopathies.
Sera from 249 patients with monoclonal gammopathies (85 multiple myeloma, 92 benign monoclonal gammopathies, 53 cryoglobulinemia, 19 Waldenström's macroglobulinemia) were examined for the presence of anti-histone activity. Thirty-four sera were found positive. In 12 of these cases the serum monoclonal immunoglobulins were purified and in all, the anti-histone activity appeared to reside in the monoclonal component. None of the patients had symptomatology of lupus despite high titers of anti-histone activity. This study demonstrates an anti-histone activity of monoclonal components of patients with monoclonal gammopathies.
