ObjectivesIn 2006, a new variant of Chlamydia trachomatis (nvCT) was discovered in Sweden. It has a deletion in the plasmid resulting in failed detection by the single target systems from Abbott and Roche used at that time, whereas the third system used, from Becton Dickinson (BD), detects nvCT. The proportion of nvCT was initially up to 65% in counties using Abbott/Roche systems. This study analysed the proportion of nvCT from 2007 to 2015 in four selected counties and its impact on chlamydia-associated complications.MethodsC. trachomatis-positive specimens collected from 2007 to 2015 were analysed by a specific PCR to identify nvCT cases. Genotyping was performed by multilocus sequence typing (MLST) and ompA sequencing. Ectopic pregnancy and pelvic inflammatory disease records were extracted from the national registers.ResultsIn total, 5101 C. trachomatis-positive samples were analysed. The nvCT proportion significantly decreased in the two counties using Roche systems, from 56% in 2007 to 6.5% in 2015 (p<0.001). In the two counties using BD systems, a decrease was also seen, from 19% in 2007 to 5.2% in 2015 (p<0.001). Fifteen nvCT cases from 2015 and 102 cases from 2006 to 2009 had identical MLST profiles. Counties using Roche/Abbott systems showed higher mean rates of ectopic pregnancy and pelvic inflammatory disease compared with counties using BD systems.ConclusionsThe nvCT proportion has decreased in all counties and converged to a low prevalence irrespective of previous rates. Genotyping showed that nvCT is clonal and genetically stable. Failing detection only marginally affected complication rates.

Abstract Background We evaluated the risk of pelvic inflammatory disease (PID), ectopic pregnancy, and infertility in women with a previous Chlamydia trachomatis (CT) diagnosis compared with women who tested negative for CT and CT untested women, considering both targeted and incidental (ie, prescribed for another indication) use of CT-effective antibiotics. Methods This was a retrospective study of women aged 12–25 years at start of follow-up within the Clinical Practice Research Datalink GOLD database linked to index of multiple deprivation quintiles, 2000–2013. CT test status and antibiotic use were determined in a time-dependent manner. Risk of PID, ectopic pregnancy, or female infertility were evaluated using of Cox proportional hazard models. Results We studied 857 324 women, contributing 6 457 060 person-years. Compared with women who tested CT-negative, women who tested CT-positive had an increased risk of PID (adjusted hazard ratio [aHR], 2.36; 95% confidence interval [CI], 2.01–2.79), ectopic pregnancy (aHR, 1.87; 95% CI, 1.38–2.54), and infertility (aHR, 1.85; 95% CI, 1.27–2.68). The PID risk was higher for women with 2 or more positive CT tests than those with 1 positive test. PID risk increased with the number of previous antibiotic prescriptions, regardless of CT test status. Conclusions We showed an association between CT-positive tests and 3 adverse reproductive health outcomes. Moreover, this risk increased with repeat CT infections. CT-effective antibiotic use showed no decreased risks of subsequent PID regardless of CT history. Our results confirm the reproductive health burden of CT, which requires adequate public health interventions.

The focus on Chlamydia trachomatis in gynecologic practice 20 years ago was in treating its potential consequences: pelvic inflammatory disease, infertility and ectopic pregnancy. Although these conditions are still important, the current focus of C. trachomatis management for the obstetrician and gynecologist is early detection and treatment. The majority of women with C. trachomatis are asymptomatic, therefore, screening programs are being devised so that C. trachomatis can be treated prior to the occurence of any adverse consequences. Novel tests have allowed the use of urine samples and self-collected vulvovaginal swabs in the detection of C. trachomatis. This article will review the consequences of C. trachomatis infection in women, methods of identification of the organism, the prevalence in various populations, and treatment and screening strategies.

Objectives: Chlamydia trachomatis infection of the upper genital tract often results in pelvic inflammatory disease (PID), and its sequels include ectopic pregnancy (EP), miscarriage and tubal infertility. This study was aimed to evaluate the rate of C. trachomatis detection as well as anti-C trachomatis antibodies in women with EP.

Pelvic inflammation has been implicated in the genesis of ovarian cancer. We conducted serologic measurements ofChlamydia trachomatisantibodies as a surrogate marker of chlamydial pelvic inflammatory disease. Women with ovarian cancer (n=521) and population-based controls (n=766) were tested. IgG antibodies to serovar D of chlamydia elementary bodies (EBs) were detected using an ELISA assay. The odds of having ovarian cancer among women with the highest titers (≥0.40 OD units) were 0.6 (95% CI 0.4–0.9). These data do not support our earlier finding of elevated titers for antibodies toC. trachomatisamong women with ovarian cancer.

ObjectivesA better understanding of Chlamydia trachomatis infection (chlamydia)–related sequelae can provide a framework for effective chlamydia control strategies. The objective of this study was to estimate risks and risk factors of pelvic inflammatory disease (PID), ectopic pregnancy and tubal factor infertility (TFI) with a follow-up time of up until 8 years in women previously tested for chlamydia in the Chlamydia Screening Implementation study (CSI) and participating in the Netherlands Chlamydia Cohort Study (NECCST).MethodsWomen who participated in the CSI 2008–2011 (n=13 498) were invited in 2015–2016 for NECCST. Chlamydia positive was defined as a positive CSI-PCR test, positive chlamydia serology and/or self-reported infection (time dependent). Data on PID, ectopic pregnancy and TFI were collected by self-completed questionnaires. Incidence rates and HRs were compared between chlamydia-positive and chlamydia-negative women corrected for confounders.ResultsOf 5704 women included, 29.5% (95% CI 28.3 to 30.7) were chlamydia positive. The incidence rate of PID was 1.8 per 1000 person-years (py) (1.6 to 2.2) overall, 4.4 per 1000 py (3.3 to 5.7) among chlamydia positives compared with 1.4 per 1000 py (1.1 to 1.7) for chlamydia negatives. For TFI, this was 0.4 per 1000 py (0.3 to 0.5) overall, 1.3 per 1000 py (0.8 to 2.1) and 0.2 per 1000 py (0.1 to 0.4) among chlamydia positives and negatives, respectively. And for ectopic pregnancy, this was 0.6 per 1000 py (0.5 to 0.8) overall, 0.8 per 1000 py (0.4 to 1.5) and 0.6 per 1000 py (0.4 to 0.8) for chlamydia negatives. Among chlamydia-positive women, the strongest risk factor for PID was symptomatic versus asymptomatic infection (adjusted HR 2.88, 1.4 to 4.5) and for TFI age <20 versus >24 years at first infection (HR 4.35, 1.1 to 16.8).ConclusionWe found a considerably higher risk for PID and TFI in chlamydia-positive women, but the incidence for ectopic pregnancy was comparable between chlamydia-positive and chlamydia-negative women. Overall, the incidence rates of sequelae remained low.Trial registrationNTR-5597.

The aim of this study was to investigate the role of Chlamydia trachomatis as a risk factor in ectopic pregnancy in Iraqi women. The study involves two groups, the first group included 24 women diagnosed as ectopic pregnancy, while the second group included 24 women as control group diagnosed as normal pregnancy. Both groups were admitted to Al-Elweya Teaching Hospital, Baghdad from November 2009 to July 2010. Serum antichlamydial antibodies were investigated in both studied groups using enzyme_linked immunosorbent assay (ELISA). Results revealed a significant(p<0.05) percentage of IgG antichlamydial antibodies in women detected as ectopic pregnant, as compared with control normal pregnant (45 vs. 8.3%). On the other hand, ectopic pregnant women exhibited low (p<0.05)IgM antichlamydial antibodies 4% as compared with control group. In conclusion all women with seropositive to Chlamydia trachomatis antibodies had pelvic inflammatory disease (PID).
