Abstract
ABSTRACT Chlamydia trachomatis (CT) is the most commonly reported sexually transmitted infection in the United States. Untreated urogenital infection in women can result in adverse sequelae such as pelvic inflammatory disease and infertility. Despite national screening and treatment guidelines, rates continue to rise; because most infections are asymptomatic, the actual prevalence of CT infection is likely significantly higher than reported. Spontaneous clearance of CT in women (in the absence of antibiotic treatment) has been described in multiple epidemiologic studies. Given the serious consequences and high prevalence of CT infection, there is growing interest in understanding this phenomenon and factors that may promote CT clearance in women. Spontaneous CT clearance is likely the result of complex interactions between CT, the host immune system, and the vaginal microbiota (i.e., the communities of bacteria inhabiting the vagina), which has been implicated in CT acquisition. Herein, we briefly review current literature regarding the role of each of these factors in spontaneous CT clearance, identify knowledge gaps, and discuss future directions and possible implications for the development of novel interventions that may protect against CT infection, facilitate clearance, and prevent reproductive sequelae.

Gamberini C, Juliana NCA, de Brouwer L, Vogelsang D, Al-Nasiry S, Morré SA, Ambrosino E. The association between adverse pregnancy outcomes and non-viral genital pathogens among women living in sub-Saharan Africa: a systematic review. FRONTIERS IN REPRODUCTIVE HEALTH 2023; 5:1107931. [PMID: 37351522 PMCID: PMC10282605 DOI: 10.3389/frph.2023.1107931] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Accepted: 05/18/2023] [Indexed: 06/24/2023] Open
Abstract
Adverse pregnancy outcomes are the main causes of maternal and neonatal morbidity and mortality, including long-term physical and psychological sequelae. These events are common in low- and middle-income countries, particularly in Sub Saharan Africa, despite national efforts. Maternal infections can cause complications at any stage of pregnancy and contribute to adverse outcomes. Among infections, those of the genital tract are a major public health concern worldwide, due to limited availability of prevention, diagnosis and treatment approaches. This applies even to treatable infections and holds true especially in Sub-Saharan Africa. As late as 2017, the region accounted for 40% of all reported treatable non-viral genital pathogens worldwide, many of which have been independently associated with various adverse pregnancy outcomes, and that include Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Treponema pallidum. Two databases (PubMed and Embase) were examined to identify eligible studies published up to October 2022. This study reviewed findings on the association between infections by treatable non-viral genital pathogens during pregnancy and adverse pregnancy outcomes among women living in Sub-Saharan Africa. Articles' title and abstract were screened at first using keywords as "sexually transmitted infections", "non-viral", "adverse pregnancy outcome", "Africa", "sub-Saharan Africa", "pregnant women", "pregnancy", and "pregnancy outcome". Subsequently, according to the eligibility criteria, potential articles were read in full. Results showed that higher risk of preterm birth is associated with Treponema pallidum, Chlamydia trachomatis and Candida albicans infections. Additionally, rates of stillbirth, neonatal death, low birth weight and intrauterine growth restriction are also associated with Treponema pallidum infection. A better insight on the burden of non-viral genital pathogens and their effect on pregnancy is needed to inform antenatal care guidelines and screening programs, to guide the development of innovative diagnostic tools and other strategies to minimize transmission, and to prevent short- and long-term complications for mothers and children.

Abstract
The aim of this study was to classify the diversity of anal HPV and non-HPV sexually transmitted infections (STIs) and compare the concordance between anal and genital infections in HIV-infected and uninfected women living in the Tapajós region, Amazon, Brazil. A cross-sectional study was performed with 112 HIV-uninfected and 41 HIV-infected nonindigenous women. Anal and cervical scrapings were collected and analyzed for HPV, Chlamydia trachomatis (CT), Neisseria gonorrheae (NG), Trichomonas vaginalis (TV), Mycoplasma genitalium (MG), and Human alphaherpesvirus 2 (HSV-2). The Kappa test evaluated the concordance between anal and genital infections. The overall prevalence of anal HPV infection was 31.3% in HIV-uninfected and 97.6% in HIV-infected women. The most frequent anal high-risk HPV (hrHPV) types were HPV18 and HPV16 in HIV-uninfected women and HPV51, HPV59, HPV31, and HPV58 in HIV-infected women. Anal HPV75 Betapapillomavirus was also identified. Anal non-HPV STIs were identified in 13.0% of all participants. The concordance analysis was fair for CT, MG, and HSV-2, almost perfect agreement for NG, moderate for HPV, and variable for the most frequent anal hrHPV types. Thus, a high prevalence of anal HPV infection with moderate and fair concordance between anal and genital HPV and non-HPV STIs was observed in our study.

Abstract
Sexually transmitted infections (STIs) are a major health problem with an estimated burden of disease transmission as high as one million new cases per day globally. Chlamydia trachomatis, a member of the genus Chlamydia, is one of the most common and curable causative agents of STIs. C. trochomatis infections usually affect sexually active young adults and adolescents; and are composed of a broad spectrum of diseases varying from asymptomatic infection to severe genito-urinary infection leading to infertility and acute or chronic ocular infection (trachoma), which may result in blindness and pneumonia. Among the members of the genus Chlamydia, there are also two pathogenic species, Chlamydia pneumoniae and Chlamydia psittaci which are responsible for acute respiratory tract infections and febrile illness in humans. The incidence, pathophysiology, and diagnostic methods are discussed in detail in the previous chapters. The purpose of this chapter is to elucidate the management of infections due to C. trachomatis, C. pneumoniae, and C. psittaci including antibiotic susceptibility and resistance mechanisms, treatment recommendations for ocular infections, genito-urinary and respiratory tract infections, and management of sex partners, pregnant women, neonates, and children according to the latest data.

Abstract
Background: A comparative analysis of the results of a survey of young people (belonging to two different generations: millennials and zoomers) on sexual behavior and awareness of STIs and HIV infection allows us to assess the existing characteristics of the sexual behavior of young people and contribute to the further improvement of preventive measures among young people regarding STI/HIV infection.
Aims: Comparative analysis of sexual behavior and assessment of the level of knowledge about STIs and HIV infection among young people (generations Y and Z).
Materials and methods: For a comparative assessment of the level of awareness on the issues of prevention and risky sexual behavior in relation to STIs and HIV infection, data from earlier sociological surveys of young people in 20012002 and in 20172020 in the city of Novosibirsk were used. Among the respondents, a questionnaire was used, consisting of 23 questions, developed by the staff of the Department of Dermatovenereology of the St. acad. I.P. Pavlov and the Center for the Sociology of Deviance and Social Control of the Institute of Sociology of the Russian Academy of Sciences, adapted by the authors. Statistical analysis was carried out using Microsoft Excel and SPSS programs. The 2 test and the independent Student's t-test were evaluated. Statistical significance was set as p0.05
Results: A total of 772 young men took part in the study, of which 321 students were interviewed in 2001-2002. (Generation Y), and 451 students in 2017-2020. (Generation Z). The results show that generations of young people (millineals and zoomers) differ from each other in terms of the source of information about STIs, sexual intercourse with strangers, condom use, and the frequency of same-sex sexual intercourse.
Conclusions: There is a positive trend in the sexual behavior of the younger generation. But a more structured promotion of STI/HIV prevention is needed, which will take into account current trends and features of obtaining information from young people.

Abstract
Chlamydia trachomatis (C. trachomatis) is the most common etiological agent of bacterial sexually transmitted infections (STIs) and a worldwide public health issue. The natural course with C. trachomatis infection varies widely between individuals. Some infections clear spontaneously, others can last for several months or some individuals can become reinfected, leading to severe pathological damage. Importantly, the underlying mechanisms of C. trachomatis infection are not fully understood. C. trachomatis has the ability to adapt to immune response and persist within host epithelial cells. Indoleamine-2,3-dioxygenase (IDO) induced by interferon-gamma (IFN-γ) degrades the intracellular tryptophan pool, to which C. trachomatis can respond by converting to a non-replicating but viable state. C. trachomatis expresses and encodes for the tryptophan synthase (TS) genes (trpA and trpB) and tryptophan repressor gene (trpR). Multiple genes interact to regulate tryptophan synthesis from exogenous indole, and persistent C. trachomatis can recover its infectivity by converting indole into tryptophan. In this review, we discuss the characteristics of chlamydial infections, biosynthesis and regulation of tryptophan, the relationship between tryptophan and C. trachomatis, and finally, the links between the tryptophan/IFN-γ axis and C. trachomatis persistence.

Abstract
There is a lack of data on the burden of Chlamydia trachomatis and Neisseria gonorrhoeae among human immunodeficiency virus- (HIV-) infected pregnant women in South Africa. We conducted a cross-sectional study which included 385 HIV-infected pregnant women attending antenatal clinic at the King Edward VIII Hospital in Durban, South Africa. The women provided vaginal swabs which were tested for C. trachomatis and N. gonorrhoeae. The prevalence of the individual STIs was as follows: C. trachomatis (47/385, 12.2%) and N. gonorrhoeae (16/385, 4.1%). Having a circumcised partner, testing positive for N. gonorrhoeae, and perceiving themselves of being at risk for infection were shown to increase the risk for C. trachomatis infection. Without controlling for the other factors, testing positive for N. gonorrhoeae increased the risk for C. trachomatis infection by 10-fold (OR: 10.17, 95% CI: 3.39-29.66, p < 0.001). Similarly, adjusting for the other factors, the risk for C. trachomatis infection in women who tested positive for N. gonorrhoeae was 9-fold (OR: 9.16, 95% CI: 2.19-40.18, p = 0.003). The following factors were associated with the increased risk of N. gonorrhoeae infection: not knowing their partner's HIV status, partner having other partners, and C. trachomatis infection status. Without controlling for the other factors, testing positive for C. trachomatis increased the risk for N. gonorrhoeae infection by 6-fold (OR: 6.52, 95% CI: 2.22-18.49, p < 0.001). Similarly, adjusting for the other factors, the risk for N. gonorrhoeae infection in women who tested positive for C. trachomatis was 6-fold (OR: 6.09, 95% CI: 1.73-22.03, p = 0.005). We found a significant association between C. trachomatis and N. gonorrhoeae in the pregnant women and the risk factors associated with these pathogens. Future studies are urgently required to investigate the impact of C. trachomatis/N. gonorrhoeae coinfections in HIV pregnant women since this data is lacking in our setting. In addition, etiological screening of C. trachomatis and N. gonorrhoeae during antenatal clinic is urgently required to prevent adverse pregnancy and birth outcomes associated with these infections.

Abstract
We investigated the vaginal microbiota (VMB) composition, prevalence of genital pathogens and their association among pregnant and post-delivery women in Pemba Island, Tanzania. Vaginal swabs were collected from 90 women, at two time points during pregnancy (<20 weeks of gestational age [GA] and ≥20 weeks GA) and once after delivery, when possible. IS-pro assay was used for VMB characterization. Chlamydia trachomatis (CT), Neisseria gonorrhea (NG), Trichomonas vaginalis (TV), Mycoplasma genitalium (MG) and human papillomavirus (HPV) were detected by qPCRs. VMB were mostly Lactobacillus dominant during pregnancy and non-Lactobacillus dominant post-delivery. A significant decrease in VMB richness was observed during pregnancy among paired and unpaired samples. Shannon diversity was significantly lower during pregnancy than post-delivery among unpaired samples. Klebsiella species and Streptococcus anginosus were the most commonly identified pathobionts at all timepoints. A high abundance of pathobionts was mostly seen in women with non-Lactobacillus dominant VMB. At ≥20 weeks GA timepoint during pregnancy, 63.0% of the women carrying one or more genital pathogen (either HPV, CT, TV, or MG) had L. iners dominant VMB. NG was not detected pre-delivery. This study contributes evidence on VMB composition, its changes during pregnancy and post-delivery, and their association with pathobionts and genital pathogens.

Abstract
Sexually transmitted diseases (STDs) affect mainly young individuals and cause health, social, and economic problems worldwide. The present study used a web questionnaire to assess the awareness, knowledge, sexual behaviors, and common practices regarding STDs in young Greek adults. The 1833 individuals, aged 18–30 years, who responded to the study seem to be particularly knowledgeable regarding STDs such as AIDS (97.7%), warts (97%), Chlamydia (92.2%), genital herpes (89.9%), syphilis (81.9%), and gonorrhea (72.1%), whereas lower percentages were noted for trichomoniasis (39.3%), Molluscum contagiosum (12.9%), mycoplasmosis (11.6%), and amoebiasis (7.4%). Regarding oral STD transmission, participants replied correctly for genital herpes (45%), warts (35.8%), and AIDS (HIV; 33.8%), whereas 30.2% were unfamiliar with oral sexual transmission. Of the participants, 52% were not aware that STDs might cause infertility. Only 40.4% of the respondents reported always using condoms during sexual intercourse, and 48.6% had never been tested for STDs. The majority of the young population (55%) presented a moderate knowledge STD score (41–60%) and was associated with demographic parameters such as age, gender, sexual preference, number of sexual partners, and residence (p < 0.05). These findings provide important information regarding the prevention of STDs and highlight the significance of developing more effective sex education programs for young people in Greece.
