Abstract
Prevalence of co-infecting sexually transmitted infections (STIs) among patients newly diagnosed with anogenital warts is under-reported. Our objective is to determine the prevalence of six common STIs, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), genital herpes (herpes simplex virus type 2 [HSV-2]), HIV, and syphilis for patients visiting a sexual health clinic in Guangzhou, China. Demographics, sexual health, and medical histories were collected at patient intake. Patients diagnosed with anogenital warts (N = 200) were invited to participate. We collected urine samples, and urethral, cervical, and rectal swabs to test for CT, NG, and MG, and blood samples for serological detection of HSV-2, syphilis, and HIV. Overall 49 (24.5%) had a co-infection (22.2% of men and 27.7% of women). All six STIs were observed among men: CT (6.8%), NG (3.4%), MG (5.1%), HIV (4.3%), HSV-2 (4.3%), and syphilis (1.7%). Women had fewer STIs, but at higher rates: CT (13.3%), MG (6.0%), and HSV-2 (8.4%). Individual men had up to two co-infections, while women had no more than one co-infection. Chlamydia was the most common STI. Patients aged 18-25 years (35.4%) had the highest prevalence. Although opportunistic screening is often applied for high-risk groups, expansion to patients with anogenital warts in all health-care settings would improve detection of problematic asymptomatic co-infections, thereby increasing China's capacity to contribute toward global surveillance systems.

Abstract
INTRODUCTION Chlamydia, gonorrhea and trichomonas are the most common curable STI. improved access to testing could reduce infection rates and prevent sequelae. nucleic acid amplification tests are the recommend class of diagnostic assay for these infections which are often asymptomatic. Areas covered: A description of the BD MAX™ System (MAX) and the BD MAX CT/GC/TV assay is provided along with data from a large US clinical trial. The capacity of the system for other tests and for lab developed assays is also described. Expert commentary: The CT/GC/TV assay on the MAX is a triplex PCR assay suitable for use with female urine and vaginal or endocervical swab samples. Male urine can be tested by ordering the CT/GC results but has not yet been evaluated for trichomonas. The assay performance characteristics are similar to those of assays run on high-throughput platforms with sensitivity ≥91.5% and specificity ≥98.6% for all analytes. Screening with the CT/GC/TV assay can be combined with testing for vaginitis which would provide a greater depth of coverage for common co-infections. The throughput is moderate (1-48 samples per 8-hour shift) but the menu includes assays beyond STI pathogens making this a suitable platform for moderate volume laboratories.

Abstract
This guideline aims to provide comprehensive information regarding the management of infections caused by Chlamydia trachomatis in European countries. The recommendations contain important information for physicians and laboratory staff working with sexually transmitted infections (STIs) and/or STI-related issues. Individual European countries may be required to make minor national adjustments to this guideline as some of the tests or specific local data may not be accessible, or because of specific laws.

Abstract
Chlamydia (C.) trachomatis female genital tract infections usually remain asymptomatic and untreated. Therefore, an adequate immune response, rather than antibiotic treatment, is essential to clear the pathogen. Most women will effectively clear C. trachomatis infections, but some will have persistent C. trachomatis infections, which may ascend to the upper genital tract and increase the risk of tubal factor subfertility. Pattern recognition receptors (PRRs) of the toll-like receptor (TLR) and nucleotide-binding oligomerization domain (NOD) families recognize C. trachomatis and initiate the immune response. Host immune factors are determinants of the course of C. trachomatis infections. Genetic variations in TLR and NOD genes may affect receptor function, leading to inadequate recognition of C. trachomatis, an inadequate immune response, and consequently an increased risk of persistence and late sequelae. For the risk assessment of tubal pathology in subfertile women, C. trachomatis immunoglobulin (Ig) G antibody testing (CAT) in serum is widely used. A positive CAT is indicative of a previous infection but not of a persistent infection. Measuring serological markers of persistence, of which C-reactive protein (CRP) seems promising, in CAT-positive women may identify a subgroup of subfertile women with persistent C. trachomatis infections and the highest risk of tubal pathology.

Population prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae in the Netherlands. Should asymptomatic persons be tested during population-based Chlamydia screening also for gonorrhoea or only if chlamydial infection is found? BMC Infect Dis 2006; 6:42. [PMID: 16522201 PMCID: PMC1450285 DOI: 10.1186/1471-2334-6-42] [Citation(s) in RCA: 16] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2005] [Accepted: 03/07/2006] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Screening and active case finding for Chlamydia trachomatis (CT) is recommended to prevent reproductive morbidity. However insight in community prevalence of gonococcal infections and co-infections with Neisseria gonorrhoea (NG) is lacking. METHODS Nested study within a large population-based Chlamydia Screening Pilot among 21.000 persons 15-29 year. All CT-positive (166) and a random sample of 605 CT-negative specimens were as well tested for gonococcal infection. RESULTS Overall Chlamydia prevalence in the Pilot was 2.0% (95% CI: 1.7-2.3), highest in very urban settings (3.2%; 95% CI: 2.4-4.0) and dependent of several risk factors. Four gonococcal infections were found among 166 participants with CT infection (4/166 = 2.4%; 95% CI: 0.1%-4.7%). All four had several risk factors and reported symptoms. Among 605 CT-negative persons, no infection with NG could be confirmed. CONCLUSION A low rate of co-infections and a very low community prevalence of gonococcal infections were found in this population based screening programme among young adults in the Netherlands. Population screening for asymptomatic gonococcal infections is not indicated in the Netherlands. Although co-infection with gonorrhoea among CT-positives is dependent on symptoms and well-known algorithms for elevated risks, we advise to test all CT-positives also for NG, whether symptomatic or asymptomatic.

Abstract
BACKGROUND Urine-based chlamydia tests enable screening in non-clinical settings. GOAL The goal of this study was to determine the prevalence of chlamydia infection among high-risk youth and young adults in non-clinical settings. DESIGN County sexually transmitted disease (STD) programs implemented chlamydia screening projects in non-clinical settings using nucleic acid amplification tests. Demographic and access to care data were collected. RESULTS Overall, 16,279 female and male youth were screened for chlamydia in 24 counties throughout California. The 158 screening venues included 32 educational, 32 correctional, and 94 community-based settings. Chlamydia infection rates varied significantly by gender, age, and venue type. Among females, the highest prevalence was found in jail settings (14.6%), juvenile detention (13.0%), and alternative schools (10.0%). Among males, the highest prevalence was found in jail (7.9%) and juvenile detention (5.8%). Venue types that serve populations with poor access to care and high rates of infection were identified. CONCLUSIONS Screening projects in non-clinical settings identify high-risk youth in need of STD care, improve access to STD screening and education, and foster local collaborations.
