The asymptomatic course of Chlamydia trachomatis (CT) infections can result in underestimated CT lifetime prevalence. Antibody testing might improve this estimate. We assessed CT antibody positivity and predictive factors thereof in the Netherlands Chlamydia Cohort Study. Women who had ≥1 CT Nucleic Acid Amplification Test (NAAT) in the study (2008–2011) and who provided self-reported information on NAATs were tested for CT major outer membrane protein specific IgG in serum (2016). CT antibody positivity was assessed and predictive factors were identified using multivariable logistic regressions, separately for CT-positive women (≥1 positive NAAT or ≥1 self-reported positive CT test) and CT-negative women (negative by study NAAT and self-report). Of the 3,613 women studied, 833 (23.1%) were CT -positive. Among the CT-negative women, 208 (7.5%, 95%CI 6.5–8.5) tested positive for CT antibodies. This increased CT lifetime prevalence with 5.8% (95%CI 5.0–6.5). Among women with a CT-positive history, 338 (40.6%, 95%CI 38.5–44.1) tested positive. Predictive factors for antibody positivity related to lower social economic status, sexual risk behavior, multiple infections, higher body mass index, and non-smoking. CT antibody testing significantly increased the lifetime prevalence. Combining NAAT outcomes, self-reported positive tests, and antibody testing reduced misclassification in CT prevalence estimates.

A prospective observational pilot study was conducted in the Netherlands between October 12, 2013 and February 21, 2014 to measure the effectiveness and safety of three immunisation options against influenza, as well as changes in participants' well-being. It appears that vaccination against influenza may not be the most effective and safest option and that the use of homeoprophylaxis against influenza should be studied in larger cohorts.
