Cervical Chlamydia trachomatis Infection Related Mucopurulent Cervicitis (MPC) among Commercial Sex Workers Attending a Private Sexually Transmitted Diseases (STD) Clinic

Abstract

Objective To study the prevalence of cervical Chlamydia trachomatis infection among
masseuses who are female commercial sex workers (CSWs), and the association
between C. trachomatis and mucopurulent cervicitis (MPC).
Design Cross-sectionalstudy.
Setting A private Sexually Transmitted Clinic (STD) affiliated with Hat Yai STD unit.
Subjects The study group was 125 masseuses work at a modern massage parlor in
Hat Yai who regularly visited the clinic to have routine check-up for common STD
every week.
Main outcome measures Chlamydial isolation, and PMN criteria of endocervical smear
stain.
Results The prevalence of cervical C. trachomatis infection is 12 in 125 cases (9.6%).
Most (11 in 12 cases) of cervical C. trachomatis infection (91.6%) had no abnormal
vaginal discharge (AVD). Half (6 in 12 cases) of cervical C.trachomatis infection
had associated with MPC. According to the PMN criteria of 10 or more, cervical
C.trachomatis infection were found 6 in glcases (6.5%) of non-MPC, and 6 in 34
cases (17.6%) of MPC. ln comparison with the PMN criteria of 30 or more, cervical
C.trachomatis infection were found 7 in 87 cases (8.0%) of non-MPC, and 5 in 38
cases (13.2/.) of MPC. There were no statistical difference (P > 0.5) between
two different PMN criteria and cervical C. trachomatis infection or MPC.
Conclusion The AVD is only suggestive information; but PMN criteria either >10 or > 30 is found to be confirmative diagnosis of MPC, but no difference is
associated with positive C. trachomatis.
