Abstract

Background. A multicenter survey was carried out in order to determine the prevalence and risk factors for Chlamydia trachomatis infection in the population of asymptomatic women in Hungary. Results were used to carry out a cost-effectiveness analysis of screening for chlamydial infection in women with asymptomatic genital infections. Methods. The non-amplified nucleic acid hybridization method (PACE 2 Gen-Probe) was used to diagnose C. trachomatis and Bayes' theorem was applied to assess the prevalence of the infection. Multiple logistic regression analysis was performed to differentiate the risk factors for chlamydial infections. Results. According to the test, the prevalence of Chlamydia trachomatis among 1300 pregnant women was 4.5%. The sensitivity and specificity of the test are estimated to be 70% and 99%, respectively. After Bayes' correction, the overall estimated prevalence of chlamydial infection was 5.1%. There were significant differences in proportions of chlamydial infection in different regions, and also in different age groups and different family status groups. The highest rate was for women aged below 20 years: 16.9%. Cost-effectiveness analysis, with associated sensitivity analysis was carried out for women aged below 20 years. Three screening strategies were compared: Using the ELISA method, using amplified Gen-Probe method and no screening. The amplified Gen-Probe method was best provided, the infection prevalence exceeded 16.7%, the PID rate exceeded 24% and the probability of tubal infertility in untreated women exceeded 25%. Conclusion. We conclude that screening with amplified Gen-Probe assays (followed by treatment of positive patients) is the preferred screening strategy for young women in Hungary.
