Resumo
Background: Co-infection by Chlamydia trachomatis (CT) in women with Human Papillomavirus (HPV) infection
has been shown to increase the risk of developing cervical intraepithelial neoplasia (CIN). The present study was
designed to analyze the association between HPV e CT co-infection and the severity of cervical neoplasia.
Methods: Two hundred fifty-one women with PCR-confirmed HPV infection were tested for CT co-infection by
PCR, prior to cervical conizations due to CIN. Prevalence rates of CT and HPV types were reported for the
histological diagnosis categories.
Results: The prevalence of Chlamydia trachomatis was 15.1% (38/251). CT negative women showed a
significant association between age ≥ 30 years and CIN 2 or worse diagnosis; this association was not found in CT
positive women. In women < 29 years of age, negative for CT, the infection by HPV 16 /18 were detected in 50% of
the women with CIN 2 or worse diagnosis and in 19.5% of women with CIN 1 or negative (OR=5.83; 95%CI:
2.19-15.57).
Conclusion: No association with CIN 2 or worse diagnosis was observed for Chlamydia trachomatis positive
women for all age groups. These data can suggest that HPV type and no CT infection may correlate with risk for
severity of histological diagnoses in younger women.
