Abstract:
A recent increase of sexually transmitted infections (STI) of rectum and anus has been observed in France, particularly in men who have sex with men. Symptoms of STI are not specific and sometimes patients have no symptom, which implies a high risk of contamination. Ulcerations, vegetant lesions and proctitis are the main anorectal lesions observed. Infection by multiple germs is frequent. STI, particulary those including ulceration, facilitate the transmission of HIV. New therapeutic strategies have to be established as antimicrobial resistance of several sexually transmitted pathogens is increasing. The treatment of sex partners of patients diagnosed with an STI is essential. Education and counseling (use of condom) taking into account each patient's individual risk factors, are the main strategies in the prevention and control of STI.
Insights
An increase in rectal and anal sexually transmitted infections (STIs) is noted, especially among men who have sex with men. Early detection and partner treatment are crucial for controlling STI spread and preventing HIV transmission.
Area of Science:
- Public Health
- Infectious Diseases
- Epidemiology
Background:
- A rise in rectal and anal sexually transmitted infections (STIs) has been observed in France.
- Men who have sex with men are disproportionately affected.
- Asymptomatic infections and non-specific symptoms increase transmission risk.
Purpose of the Study:
- To highlight the growing concern of anorectal STIs.
- To emphasize the link between STIs and HIV transmission.
- To call for updated therapeutic and preventive strategies.
Main Methods:
- Observational analysis of STI trends.
- Clinical observation of anorectal lesions.
- Review of current treatment and prevention protocols.
Main Results:
- Common anorectal lesions include ulcerations, vegetant lesions, and proctitis.
- Co-infections with multiple pathogens are frequent.
- Antimicrobial resistance is an increasing challenge.
Conclusions:
- STIs, particularly those causing ulcerations, facilitate HIV transmission.
- New therapeutic strategies are needed due to rising antimicrobial resistance.
- Partner treatment and patient education on risk factors and condom use are essential for STI control.
