Results from a large cross-sectional study assessing Chlamydia trachomatis, Ureaplasma spp. and Mycoplasma hominis urogenital infections in patients with primary infertility.

ABSTRACT: Female and male infertility have been associated to Chlamydia trachomatis, Ureaplasma spp. and Mycoplasma hominis urogenital infections. However, evidence from large studies assessing their prevalence and putative associations in patients with infertility is still scarce. The study design was a cross-sectional study including 5464 patients with a recent diagnosis of couple's primary infertility and 404 healthy control individuals from Cordoba, Argentina. Overall, the prevalence of C. trachomatis, Ureaplasma spp. and M. hominis urogenital infection was significantly higher in patients than in control individuals (5.3%, 22.8% and 7.4% vs. 2.0%, 17.8% and 1.7%, respectively). C. trachomatis and M. hominis infections were significantly more prevalent in male patients whereas Ureaplasma spp. and M. hominis infections were more prevalent in female patients. Of clinical importance, C. trachomatis and Ureaplasma spp. infections were significantly higher in patients younger than 25 years. Moreover, Ureaplasma spp. and M. hominis infections were associated to each other in either female or male patients being reciprocal risk factors of their co-infection. Our data revealed that C. trachomatis, Ureaplasma spp. and M. hominis are prevalent uropathogens in patients with couple's primary infertility. These results highlight the importance of including the screening of urogenital infections in the diagnostic workup of infertility.

Project description:ObjectivesTo review the literature for non-standard treatment options for uncomplicated Chlamydia trachomatis (CT) infections in adolescents and adults.DesignSystematic review.Data sourcesOvid MEDLINE/PubMed, Ovid EMBASE, Cochrane Trials & Systematic Review Databases, CINAHL Plus with Full Text, Web of Science Core Collection, Scopus, ProQuest Dissertations & Theses Global, ClinicalTrials.gov and Health Canada Trials Database were searched for studies in English or French from 1 January 2006 to 6 August 2017. Keywords included CT, anti-infective or anti-bacterial agents, therapy/pharmacotherapy/management.Review methodsIncluded were primary research studies. Outcome measures included clinical or microbiological cure, treatment failure and adverse events. We followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were assessed for risk of bias using the Revised Cochrane Risk of Bias V.2.0 tool for randomised and the Newcastle-Ottawa Quality Assessment Scale for non-randomised studies.Funding sourcePublic Health Agency of Canada.ResultsOf the 6899 records identified through the database search, 11 studies were included. One randomised controlled trial reported that delayed release doxycycline was non-inferior to azithromycin. Two studies examined higher doses of azithromycin but reported no additional benefit. One study looked at a 5-day azithromycin treatment regimen and reported a high cure rate. Two studies reported efficacy of sitafloxacin, and a single study supports the use of levofloxacin. Two phase 2 studies reported efficacy of single-dose rifalazil in both men and women. Only one retrospective study was identified that examined treatment in pregnant women and reported that efficacy with single-dose azithromycin exceeded that of amoxicillin and erythromycin. A single study examining the efficacy of a beta-lactam antibiotic was stopped early due to high treatment failures.ConclusionsThe paucity of existing data highlights the need for further adequately powered studies to evaluate rifalazil, delayed release doxycycline, levofloxacin and other agents for the treatment of uncomplicated CT infections.Prospero registration numberCRD42017073096.
