[Circulating immune complexes in primo-secondary and serological syphilis (author's transl)].

Some clinical features of syphilis suggest that immune complexes may be a pathogenetic factor in the syphilitic lesions. Recently, circulating immune complexes have been reported in six patients with secondary syphilis by Søling et al. In our study, the presence of circulating immune complexes was investigated in 42 patients with syphilis (primary, secondary, serological) by the method of C1q binding test.
