Does partner notification of men with asymptomatic non-gonococcal non-chlamydial urethritis identify chlamydia-positive women?

The objective of this study was to identify the proportion of female contacts of men diagnosed with non-gonococcal non-chlamydial urethritis (NGNCU) who had chlamyclial infection, muco-purulent cervicitis (MPC), pelvic inflammatory disease (PID) or other genital infections, and to determine whether chlamyclial rates are higher in women who are contacts of men with NGNCU. A retrospective case-note review of men with NGNCU and their traced female contacts was performed. Seventy-five men were included in the study, of whom 75% were caucasian and 49% were asymptomatic. Twenty-four women were successfully traced equating to 0.32 contacts per index man. In total, 46% of the women were contacts of asymptomatic men. Overall, 26% of women were identified with chlamyclial infection, increasing to 36% in the contacts of asymptomatic men. The diagnosis and partner notification of men with asymptomatic NGNCU does identify female contacts with high chlamydial infection rates. However, such targeting is resource-intensive and invasive urethral screening may deter asymptomatic men from attending. It is likely that the needs of the whole health community will be better served by screening a greater number of men and operating an active partner notification system.
