Syphilis and AIDS

Abstract

Evidence is shown that syphilis has become a major public health problem again. From 1988 to 1995 the permanently growing number of new cases of syphilis in the world was observed. The majority of the syphilitic cases in the patients are difficult for curing. The central nervous system is often involved in early syphilis. Previously the neurosyphilis was very rare. The reason for development of this stage of syphilis, may be an inadequate treatment as well as a weakening of the immunological responses. The latter one very often is caused by additional non-symptomatic infection including human immunodeficiency virus (HIV). Syphilitic ulcers act as a portal of entry for HIV. Analysis of cases with double infection with Treponema pallidum and HIV indicate that HIV infection may accelerate the course of syphilis and the presence of syphilis may also have influence on progression of the chronic HIV infection to AIDS. Taking into account that HIV infection alters the response to the treatment also, one can suggest that all of the patients with syphilis should be examined for the presence of HIV infection.
