The intersection between HIV and syphilis in men who have sex with men: some fresh perspectives.

Abstract

Syphilis is increasing in men who have sex with men and disproportionately affects HIV-infected men. Here we review the epidemiology, diagnostic techniques, treatment guidelines, follow-up procedures and control of syphilis. The difference in these factors in HIV-infected men and uninfected men and evidence for this is reviewed. We explain that HIV-infected men are at higher risk of syphilis acquisition as a result of different behavioral factors. Thus, some control strategies may be different for HIV-infected men owing to these factors and also because HIV-infected men are more closely linked with medical care. There is no strong evidence to suggest there should be any differences in diagnostic techniques, treatment guidelines or follow-up procedures between HIV-infected and uninfected men.
