| Abstract: | Ectopic pregnancy is one of the most serious sequelae to acute salpingitis. Chlamydia trachomatis seems to be the most common etiologic agent of acute salpingitis. In the present study, we tested whether women with ectopic pregnancy had serologic evidence of a current or past chlamydial infection. Sixty-five percent of the women with ectopic pregnancy had IgG serum antibodies to C. trachomatis, and 21% of women pregnant in utero had such antibodies. Eleven percent of women with infertile husbands, 42% of women with cervicitis, and 69% of women with salpingitis had IgG serum antibodies to C. trachomatis. In women with ectopic pregnancy, there was a correlation between the occurrence of IgG antibodies and a history of salpingitis or gross evidence of a previous tubal inflammation. We conclude that previous chlamydial salpingitis may be a major etiologic factor leading to ectopic pregnancy. |
