Colposcopy Clinic

Background: Chlamydia trachomatis is a major public health issue, with notifications of this sexually transmitted disease continuing to rise in Australia. Women attending colposcopy clinics are referred for treatment of cervical abnormalities often associated with human papilloma virus (HPV) infection. There is evidence that women who have acquired one sexually transmitted infection, such as HPV, are at higher risk of acquiring another. Women attending colposcopy clinics may therefore be at risk of undiagnosed infection with C. trachomatis. Aim: To determine the prevalence of C. trachomatis in women attending a public metropolitan colposcopy clinic in Victoria. Methods: A cross-sectional study was performed. Institutional ethics committee approval and informed consent were obtained. Consecutive women attending the colposcopy clinic completed a questionnaire and had a swab collected from the endocervix for analysis by polymerase chain reaction for C. trachomatis. Positive screens were treated in accordance with best practice. Data were analysed with Minitab Version 2004 (Minitab Inc, State College, PA, USA). Results: Of 581 women approached to participate in the trial, consent was obtained from 568 women (98%) and final outcome data was available on 560 women (99%). The overall rate of chlamydial infection was 2.1% (95% CI 1.5–2.7%). However, in women aged 25 years or less the rate was 5.8% (95% CI 3.8–7.8%) and in women over 25 years it was only 0.9% (95% CI 0.4–1.4%). Apart from age, no other demographic factor was significantly associated with chlamydial infection. Conclusion: Although the prevalence of chlamydial infection in the colposcopy clinic population as a whole does not warrant a policy for routine screening, screening directed at women aged 25 years or less would gain the greatest yields in terms of cost efficacy. Such a policy should be implemented as standard practice.

Abstract Background Recommendations for sexually transmitted infection (STI) screening vary significantly across countries. This study evaluated the prevalence of urogenital and extragenital infections with Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Mycoplasma genitalium (MG) in patients visiting a French STI clinic in the Indian Ocean region to determine whether current STI screening practices should be updated. Methods This cross-sectional study examined all patients who visited the STI clinic between 2014 and 2015. Triplex polymerase chain reaction screening for CT, NG, and MG was performed on urine, vaginal, pharyngeal, and anal specimens (FTD Urethritis Basic Kit, Fast Track Diagnostics, Luxembourg). Results Of the 851 patients enrolled in the study, 367 were women (367/851, 43.2%) and 484 were men (484/851, 56.0%). Overall, 826 urogenital specimens (826/851, 97.1%), 606 pharyngeal specimens (606/851, 71.2%), and 127 anal specimens (127/851, 14.9%) were taken from enrolled patients. The prevalence of urogenital CT and MG was high in women ≤25 years (19/186, 10.21%; 5/186, 2.69%) and in men who have sex with women ≤30 years (16/212, 7.54%; 5/212, 2.36%). Among patients with urogenital CT infection, 13.7% (7/51) had urethritis. All patients with urogenital MG infection were asymptomatic. Men who have sex with men had a high prevalence of pharyngeal CT (2/45, 4.44%) and NG (3/44, 6.81%) and a high prevalence of anal CT (2/27, 7.41%), NG (2/27, 7.40%), and MG (1/27, 3.70%). After excluding patients with concomitant urogenital infection, extragenital infections with at least 1 of the 3 pathogens were found in 20 swabs (20/91, 21.9%) taken from 16 patients (16/81, 19.7%), all of them asymptomatic. Conclusions Routine multisite screening for CT, NG, and MG should be performed to mitigate the transmission of STIs in high-risk sexually active populations.

Human papillomavirus (HPV) is the most common sexually transmitted infection in the world. Several studies have shown a higher prevalence of HPV infection in HIV-infected women. The aim of this study was to determine the prevalence and the genotype diversity of HPV infection in HIV-infected women. From April 2010 to December 2012 cervical specimens were collected from 169 HIV-infected women who screening for cervical cancer at Reference Unit in Belém. The detection of HPV infection was performed by nested PCR and HPV type was performed using a commercial system. The prevalence of HPV infection was 63.3%. Of the 47 genotyped samples, 40.4% was found positive for high risk-HPV 16 and 12.8% for high risk-HPV 52. HPV infection was predominant in the group of women with no incidence of cytological abnormalities and more prevalent in women of reproductive age, unmarried, low education level, and who reported use condoms during sexual intercourse. It was observed an association between HPV infection and independent variables, such as condom use, multiple sexual partners, and history of sexually transmitted diseases. High-risk types of HPV infection were prevalent in our study. Infection with multiple high-risk HPV genotypes may potentiate the development of cervical cancer in HIV-infected women.

Sexually transmitted infections are an important public health issue. The purpose of this study is to analyse the association between different sexual habits and the prevalence of sexually transmitted infections in the population of Granada who consult with a specialised centre. An observational, cross-sectional study was conducted based on the medical records of 678 people from the Sexually Transmitted Diseases and Sexual Orientation Centre of Granada, who were diagnosed positively or negatively with a sexually transmitted infection, during the 2000−2014 period. Sociodemographic and clinical data, as well as data on frequency and type of sexual habits, frequency of condom use and sexually transmitted infection positive or negative diagnosis were collected. Univariate and bivariate analyses were conducted. The most popular sexual habits were vaginal intercourse, oral sex (mouth–vagina and mouth–penis) and the least popular were anus–mouth and anal sex. The use of condom is frequent in vaginal and anal sex and less frequent in oral sex. Sexually transmitted infection is associated with mouth–penis (p = 0.004) and mouth–vagina (p = 0.023) oral sex and anal sex (p = 0.031). It is observed that there is a relationship between the presence of STIs and oral sex practices, people having such practices being the ones who use condoms less frequently. There is also a relationship between anal sex and the prevalence of STIs, although in such sexual practice the use of condom does prevail.

Objective: Human Papilloma Virus (HPV) infection is the most common sexually transmitted among young people of both sexes. It is also the main cause of cervical cancer. This study aimed at assessing students’ knowledge and health beliefs about HPV infection and the use of the vaccine.Methods: The sample of the cross-sectional study was 120 randomly selected nursing students from the Faculty of Public Health, University of Vlore “Ismail Qemali” Albania. Anonymous, self-administered questionnaire based on the literature and Health Belief Model, was used for data collection in May 2017. The questionnaire included assessment questions for students’ knowledge and health beliefs about HPV and vaccine use. Also, questions about socio-demographic characteristics were included. Data analysis included the calculation of averages, frequencies, and confidence intervals. P values ≤0.05 were accepted as statistically significant.Result: Mean age 20.3±2.2 years, 92.44 % of students were female. 65.83% of students know that HPV is a sexually transmitted infection and a vaccine is available to prevent it. Ambiguities and uncertainties exist in regard to screening with Pap test after vaccination. Perceived benefits are high for 50.83% of students. Perceived severity appeared low as only 25% of students agree that they may be affected by HPV. Statistical association, p =0.0347 was found between perceived risk and the year of study. The parents’ role in vaccination against HPV have a strong statistical association, p=0.0058 with the year of study as only 8.33 % of students in the third year agree with the fact that that parents do not allow them to be vaccinated against HPV. Conclusion: The study noted the student’s ambiguity and misconceptions about HPV infection. Low severity and lack of knowledge about the vaccine emphasizes that identifying their current level of knowledge and the main source of information are essential to provide comprehensive and appropriate health education.

Abstract Background Chlamydia trachomatis (CT) is a common sexually transmitted infection (STI) with significant morbidity. The study aimed to explore the willingness to undergo routine CT screening and its associated factors among hospital-based patients in Shenzhen. Methods We used data from the Shenzhen Gonorrhea and Chlamydia Intervention Programme. Participants were recruited with a stratified purposeful sampling design from 1 April 2018 to 16 May 2018. A structured questionnaire was used to obtain data on baseline characteristics and CT-related participant information. Results Of the 16,546 participants, 64.79% were women, with a mean age of 31.85 ± 7.31 of all participants. Of the participants, 88.78% were willing to undergo routine CT screening. According to multivariate logistic regression analyses, willingness to undergo routine CT screening was associated with the following (P < 0.05): being a woman (AOR = 1.53, 95% CI = 1.34–1.75), one year or more residency in Shenzhen (AOR = 1.64, 95% CI = 1.37–1.95), any secondary education (AOR = 2.46, 95% CI = 1.92–3.15), monthly income ≥ RMB 10,000 (AOR = 1.24, 95% CI = 1.01–1.51), having forgotten CT diagnosis history (AOR = 1.42, 95% CI = 1.12–1.79), without current STI-related symptoms (AOR = 1.24, 95% CI = 1.10–1.41), and having correct understanding of the sequelae of CT infection (AOR = 1.68, 95% CI = 1.39–2.03). Conclusion This study reported high willingness to undergo routine CT screening among hospital-based patients in Shenzhen, and provided evidence for the promotion and the implementation of strategies and recommendations on routine CT screening in China.

Abstract Background Pharyngeal and rectal Neisseria gonorrhoeae and Chlamydia trachomatis play important roles in infection and antibacterial resistance transmission, but no US Food and Drug Administration (FDA)–cleared assays for detection at these sites existed prior to this study. The objective was to estimate performance of assays to detect those infections in pharyngeal and rectal specimens to support regulatory submission. Methods We performed a cross-sectional, single-visit study of adults seeking sexually transmitted infection testing at 9 clinics in 7 states. We collected pharyngeal and rectal swabs from participants. The primary outcome was positive and negative percent agreement for detection of N. gonorrhoeae and C. trachomatis for 3 investigational assays compared to a composite reference. Secondary outcomes included positivity as well as positive and negative predictive values and likelihood ratios. Subgroup analyses included outcomes by symptom status and sex. Results A total of 2598 participants (79% male) underwent testing. We observed N. gonorrhoeae positivity of 8.1% in the pharynx and 7.9% in the rectum and C. trachomatis positivity of 2.0% in the pharynx and 8.7% in the rectum. Positive percent agreement ranged from 84.8% to 96.5% for different anatomic site infection combinations, whereas negative percent agreement was 98.8% to 99.6%. Conclusions This study utilized a Master Protocol to generate diagnostic performance data for multiple assays from different manufacturers in a single study population, which ultimately supported first-in-class FDA clearance for extragenital assays. We observed very good positive percent agreement when compared to a composite reference method for the detection of both pharyngeal and rectal N. gonorrhoeae and C. trachomatis. Clinical Trials Registration NCT02870101.

Abstract Background Chlamydial infection is a difficult-to-diagnose type of sexually transmitted disease that occurs mainly in young people. We report a case of bowel obstruction caused by intrapelvic adhesions formed by chlamydial infection. Case presentation This patient was a 23-year-old woman who had been suffering from acute abdominal pain. She had been previously treated several times for intrapelvic abscesses and had a history of chlamydial infection. Endometriosis was thought to be the cause of her pelvic abscess based on endoscopic findings. Computed tomography demonstrated a small bowel obstruction caused by a pelvic abscess. However, the diagnosis could not be confirmed. She underwent laparoscopic surgery and was diagnosed with bowel obstruction due to adhesion of chlamydial infection based on the intraoperative findings and Chlamydia trachomatis antibody test. She was discharged 5 days after surgery. Conclusions It is necessary to consider the possibility of chlamydial infection as a cause for lower abdominal pain and unexplained bowel obstruction in female patients.

Chlamydia trachomatisis a leading cause of sexually transmitted infection worldwide and responsible for myriad of immunopathological changes associated with reproductive health. Delayed secretion of proinflammatory chemokine interleukin (IL)-8 is a hallmark of chlamydial infection and is dependent on chlamydial growth. We examined the effect of iron chelators on IL-8 production in HeLa 229 (cervix epitheloid cell, CCL2) cells infected withC. trachomatis. IL-8 production was induced by Iron chelator DFO and Mimosine, however, synergy with chlamydial infection was obtained with DFO only. Temporal expression of proinflammatory secreted cytokines IL-1beta, TNF-alpha, and IL-8 did not show synchrony inChlamydia trachomatisinfected cells. Secretion of IL-8 from Hela cells infected withC. trachomatiswas not dependent on IL-1 beta and TNF- alpha induction. These results indicate towards involvement of iron in chlamydia induced IL-8 production.

OBJECTIVE: To discuss the occurrence of genital chlamydia in developed countries and review the literature assessing the potential risk factors for this sexually transmitted disease.DATA SOURCES: A MEDLINE search was performed for all English citations from 1985 to 2000 that contain the keywords "Chlamydia trachomatis", "chlamydial infections", "risk factors" and "sex behaviour". All relevant references cited in articles that were obtained from the search were also included.DATA EXTRACTION: All articles obtained from the above sources were examined, and were included in the review if they met the following criteria: primary study examining sociodemographic or behavioural risk factors associated with genital chlamydial infection using multivariate analysis; study subjects 12 years of age and older; and study setting in a developed country.DATA SYNTHESIS AND CONCLUSIONS: Genital chlamydial infection has become the most commonly reported bacterial infection in North America over the past decade. Thirty-eight cross-sectional studies and six cohort studies were included in the present review. Most studies demonstrated that young men and women are at higher risk of being infected with chlamydia than older subjects. Chlamydia seems to be found in a diverse group of people, and unlike gonorrhea, is not concentrated in low income, minority core groups with high rates of partner change. However, a number of studies have shown that communities with well-established control programs are beginning to demonstrate this pattern. There is no clear evidence that chlamydia is associated with type of partners, contraceptive use, or age at first intercourse. Future research should follow this sexually transmitted disease as it evolves through the epidemiological stages to ensure that preventive and treatment services are reaching those people who are most likely to be infected.
