[Syphilis: what's new?]

Area of Science:

• Infectious Diseases
• Microbiology
• Public Health

Background:

• Syphilis, caused by Treponema pallidum, is experiencing a significant resurgence, particularly within the men who have sex with men (MSM) community since the late 1990s.
• The disease presents diagnostic challenges, relying on serological tests and direct examination of mucocutaneous lesions.
• Early neurological and ophthalmological manifestations are common and can lead to severe functional impairment.

Purpose of the Study:

• To review recent advancements and current understanding of syphilis epidemiology, diagnosis, and management.
• To highlight the importance of early detection and treatment in mitigating long-term complications.
• To emphasize the role of serological markers in monitoring treatment efficacy.

Main Methods:

• Review of current diagnostic techniques, including serological assays and direct microscopic examination.
• Analysis of established and emerging treatment protocols, focusing on benzathine penicillin and doxycycline.
• Evaluation of treatment effectiveness based on the reduction of quantitative Venereal Disease Research Laboratory (VDRL) test results.

Main Results:

• Serological testing remains the cornerstone of syphilis diagnosis, often supplemented by direct lesion examination.
• Intramuscular benzathine penicillin and oral doxycycline are the primary treatment options.
• A decrease in quantitative VDRL titers serves as the key indicator for successful treatment.

Conclusions:

• The ongoing resurgence of syphilis necessitates heightened awareness and diagnostic vigilance.
• Prompt and appropriate treatment, guided by VDRL monitoring, is crucial for preventing severe neurological and ophthalmological sequelae.
• Continued research and public health interventions are vital to control the spread of this infection.
