Syphilis with HIV in Florence, 2003-2009: a 7-year epidemiological study

Area of Science:

• Infectious Diseases
• Epidemiology
• Public Health

Background:

• Syphilis incidence has seen a resurgence globally.
• Understanding transmission dynamics and co-infections is crucial for effective control.
• HIV co-infection presents unique diagnostic and management challenges.

Purpose of the Study:

• To analyze trends in acquired syphilis in Florence and its province over a 7-year period (2004-2008).
• To investigate sexual behaviors among individuals diagnosed with syphilis.
• To examine the prevalence and characteristics of syphilis/HIV co-infection.

Main Methods:

• Retrospective analysis of 259 acquired syphilis cases.
• Data collection on patient demographics (age, sex) and HIV status.
• Assessment of transmission routes and clinical presentation.

Main Results:

• A significant increase in syphilis cases by 248% from 2004 to 2008.
• Men who have sex with men (MSM) were a predominant group among male and HIV-positive patients.
• Oral sex identified as a major transmission route, often unrecognized by patients.
• 33% of HIV-positive patients were late-presenters, with syphilis being the initial indicator of HIV infection.

Conclusions:

• The study highlights a dramatic rise in acquired syphilis in the Florence area.
• Sexual behaviors, particularly oral sex among MSM, are critical factors in transmission.
• Syphilis can serve as an early diagnostic marker for undiagnosed HIV infection, facilitating timely intervention.
