To obtain an estimate of the prevalence of chlamydia and gonorrhoea among men and women aged 18 to 34 years.
To asess whether the Chlamydia Antibody Test (CAT), used to determine the presence of antichlamydia IgG antibodies in serum for diagnostics in the fertility clinic, can serve as an intermediate marker for PID/tubal pathology caused by Chlamydia.
Assess duration of Ct positivity in the 8 weeks after treatment as well as the Ct bacterial load and RNA in time-sequential samples
We will investigate whether Chlamydia IgG antibody presence and titers in vaginal swabs (mucosa-CAT) are comparable to antibodies found in serum (serum-CAT), and as such could serve as a marker for a past Chlamydia infection with an enhanced risk of…
The main objective is to map sexual and other sexually transmitted Infections (STI)-related risk behaviour, prevalence and incidence of STI in swingers and identify determinants for STI spread.Secondary objectives are:A. Describe the (sexual)…
This study is being conducted to provide performance evaluation data for the cobas 4800 CT/NG Test. This data will be used as part of the cobas 4800 CT/NG Test CE submission package. Comparison with a 'state of the art' technique (Abbott…
The aim of this pilot implementation is first to make a serious start in Chlamydia screening and secondly to determine feasibility, affectivity and cost-effectivity. The results of this pilot implementation will be leading for the decision about the…
To understand the transmission and acquisition of anorectal CT infections in women (i.e. to and from their male sexual partners and to and from the anal and genital region of the same woman), in women who receive routine care, in order to inform…
The aim of this study is to determine the optimal anatomical sample site for the evaluation of CT viability by comparing the total CT load (as determined by route NAAT) and viable CT load (by V-PCR) from different anatomical sample sites.
To obtain an estimate of the prevalence of chlamydia and gonorrhoea among men and women aged 16.5 to 34 years.
The aim of the NEtherlands Chlamydia Cohort STudy (NECCST) is to assess the risk of developing complications and the time to pregnancy in women with and without a known previous Ct infection. Furthermore, this study aims at determining host genetic…
in this study we aim to investigate incidence of eleven Chlamydia species in deep respiratory secretionss from patients with community acquired pneumonia. The additional value of faecal samples will be investigated. In addition, we aim to…
1)to gain insight into the prevalence of HIV and other STDs among transgender people. 2) to identify determinants that are associated with HIV and STD presence (through optional questionnaires).
1. What is the prevalence of rectal chlamydia in women tested for cervical chlamydia in the general practitioners practise.2.Wat is the correlation between the sexual history en the results of rectal testing for chlamydia. In other words: predicts…
We aim to study the link between behavioural and psychological determinants and chlamydia (re-)infection, and to develop mathematical models for curable STI incorporating these determinants to be able to better estimate the impact of interventions.
