Chlamydial serology among patients with tubal factor infertility and ectopic pregnancy in Alexandria, Egypt.
OBJECTIVE
Little is known about the role of Chlamydia trachomatis in the etiology of tubal factor infertility and ectopic pregnancy in Egypt.


OBJECTIVE
To assess the association between past chlamydial infection, tubal factor infertility, and ectopic pregnancy in an Egyptian population.


METHODS
This report consists of two concurrent case-control studies. First, 51 patients with tubal factor infertility were compared with 48 healthy subjects who did not have tubal factor infertility and 53 pregnant subject subjects. Second, 66 patients with ectopic pregnancy were compared with 51 pregnant control subjects.


RESULTS
Geometric mean titers for Chlamydia trachomatis were higher among patients with tubal factor infertility and ectopic pregnancy, and they were more likely to have high antichlamydial titers (> or = 1:128 immunoglobulin G). Serum titer was significantly correlated with histologic evidence of salpingitis among the patients with an ectopic pregnancy.


CONCLUSIONS
Our findings, similar to those from Western societies, suggest that among Egyptian women, prior chlamydial infection is associated with an increased risk of tubal factor infertility and possibly ectopic pregnancy.
