Association between Chlamydial Infection with Ectopic and Full-Term Pregnancies: A Case-Control Study

Area of Science:

• Reproductive Health
• Infectious Diseases
• Obstetrics & Gynecology

Background:

• Ectopic pregnancy (EP) poses a significant risk to maternal health if not diagnosed early.
• Limited data exists on the association between chlamydial infection and EP in Southeast Asia.
• Understanding risk factors is crucial for timely diagnosis and intervention.

Purpose of the Study:

• To compare the prevalence of chlamydial infection in women with EP versus those with full-term pregnancies.
• To identify classical risk factors associated with EP in the study population.
• To assess the rupture status and severity of EP cases.

Main Methods:

• A case-control study involving 72 women with EP and 69 with full-term pregnancies in Malaysia.
• Data collection included demographic, clinical information, and intraoperative findings.
• Chlamydial infection was assessed via blood sample IgG levels.

Main Results:

• Women with EP showed a higher prevalence of chlamydial infection (34.7%) compared to controls (13.0%).
• The adjusted odds ratio for EP associated with chlamydial infection was 4.18 (p=0.002).
• A significant proportion of EP cases (52.8%) presented with rupture, often after six weeks gestation, with substantial blood loss.

Conclusions:

• The study indicates a significant association between prior chlamydial infection and ectopic pregnancy in this Malaysian cohort.
• Many EP cases lacked traditional risk factors, underscoring the importance of infection screening.
• Findings suggest a need to integrate chlamydia screening into early pregnancy care to mitigate EP risks.
