Abstract

Although interferon-γ has been associated with control of chlamydial infections in mice, no direct evidence links it to human chlamydial infections. Therefore, interferon-γ was assayed by ELISA in endocervical secretions and plasma of women cultured for Chlamydia trachomatis. Women with positive endocervical chlamydial cultures had increased levels of interferon-γ in endocervical secretions (6.7 ± 2.8, mean ± SE, n = 47) compared with uninfected women (1.4 ± 0.4, n = 52) (P = .002). Interferon was also present in secretions of women with gonorrhea. Higher levels were seen in secretions from older women with positive chlamydial cultures. Interferon levels in secretions did not correlate with simultaneous plasma levels, the number of organisms recovered in tissue culture, or clinical correlates of inflammation. These data suggest that interferon-γ is present at the site of chlamydial infection; however, further experiments are needed to determine whether interferon is specifically involved in protection or is a nonspecific indicator of inflammation.
