[Genital chlamydia infections and extrauterine pregnancy].

Serum samples of 217 patients with ectopic pregnancy (e.p.) and of 152 women with intrauterine pregnancy (i.u.p.) were examined for their antibody content to chlamydia trachomatis by means of the indirect immunofluorescence technique. In 81% of the sera of patients with e.p., antibody could be detected, while patients with i.u.p. revealed antibody in 39%. Titres greater than or equal to 1:128 were found in 49% (e.p.) and in only 11% (i.u.p.) respectively; so they possess a high diagnostic value. These results show significant differences in the behaviour of antibodies in both groups of patients and are illustrated in 2 charts. Anamnestic data showed 54% of the patients with e.p. (i.e. adnexitis 23%, gonorrhea 12.3%, previous e.p. 18.4%); the mean age was 29 years. Affected tubes may lose their physiological function, possibly resulting in an ectopic pregnancy. The level of antibody in the serum remains stabile for many years, this enables a retrospective diagnosis of chlamydial infections. An early diagnosis and treatment, including the partners, represent the best way for prevention of complications.
