[Chlamydia trachomatis: should it be systematically be screened or treated? Literature review and cost/benefit estimation in France].
Chlamydia trachomatis is a primary cause of acute or silent salpingitis leading to infertility and ectopic pregnancy. The C. trachomatis epidemic, undiscovered in most cases, spreads, mostly in adolescents, during the years following the onset of sexual activity. As opposed to gonococcal infection which has greatly decreased, C. trachomatis cervical and urethral infection is commun in young occidentals. More then 30 different studies covering 200-12000 subjects screened in family planning centers, college women and men, students and military recruits in different parts of the USA, in Scandinavian countries and France, indicate a prevalence of 5-20% (mean 10%) in apparently healthy young females < 25 years and 5-10% in males. Female prevalence is strongly related to age, being highest (5-20%) in women < 20 years old. Several cost-benefit analysis show that the total cost of the general screening in young populations, which can easily be carried out for women in family planning centers, could save twice the cost of treatment for pelvic inflammatory disease caused by C. trachomatis and six times the total cost of C. trachomatis epidemics if late sequelae are taken into account (tubal infertility treatment, ectopic pregnancy). In France, screening should save 12 to 48 millions French francs each year, depending of the cost of detection. The final benefit of detection should be the eradication of the epidemic as obtained to date in Scandinavian countries.
