Testing for cervical Chlamydia trachomatis infection in an inner city practice

Area of Science:

• Gynecology
• Infectious Diseases
• Public Health

Background:

• Cervical Chlamydia trachomatis infections are a significant public health concern.
• Early detection and treatment are crucial to prevent long-term complications.
• Screening policies need to be effective, especially in high-risk populations.

Purpose of the Study:

• To determine the prevalence of cervical Chlamydia trachomatis infection in women undergoing speculum examinations.
• To identify risk factors associated with chlamydial infection.
• To develop a rational policy for chlamydia testing in a deprived inner London practice.

Main Methods:

• A prospective study involving 409 women aged 17-45 attending for cervical smear or vaginal examination.
• Chlamydia testing performed using the direct immunofluorescent test.
• Assessment of risk factors including age, sexual history, and clinical signs like purulent vaginal discharge and cervicitis.

Main Results:

• The prevalence of cervical Chlamydia trachomatis infection was 8.8% (36 out of 409 women).
• Significant associations were found between chlamydia infection and purulent vaginal discharge or inflammatory cervical smears.
• Age, multiple sexual partners, and history of infection were assessed as potential risk factors.

Conclusions:

• Given the prevalence and potential consequences of untreated chlamydial cervicitis, universal screening for young women attending for speculum examinations is ideal.
• If universal screening is not feasible, targeted chlamydia testing should be offered to women in high-risk groups.
• Identifying women with purulent vaginal discharge or inflammatory cervical smears is key for targeted screening.
