Immunosuppression in patients with syphilis and problems of human immunodeficiency virus infection.

An investigation of the induced suppression and cytotoxicity of T lymphocytes, carried out in 57 patients with different forms of syphilis, has made it possible to find some reasons for the depression of cell-mediated immunity (CMI) in patients with early syphilis. The analysis of the immunoreaction of patients with different forms of syphilis clarifies the influence of the human immunodeficiency virus (HIV) on the dynamics and formation of syphilis manifestations.
