Sexually Transmitted Infections in Pregnancy and Reproductive Health: Proceedings of the STAR Sexually Transmitted Infection Clinical Trial Group Programmatic Meeting

Associations between socio-demographics, sexual knowledge and behaviour and sexually transmitted infections among reproductive-age women in Southeast Asia: Demographic Health Survey results

Sexually Transmitted Infections (STIs) seriously affect population morbidity, mortality, and are a major public health problem worldwide. A cross-sectional study was conducted using the latest Demographic and Health Survey (DHS) data published between 2005 and 2022 for five Southeast Asian countries. The study's focus was on STI risk factors in the DHS of Timor-Leste, Philippines, Indonesia, Myanmar, and Cambodia. The study included 139,062 women of reproductive age, aged 15 to 49 years, who reported whether they had experienced an STI or its symptoms and had comprehensive information on the variables of interest, including socio-demographics, sexual behaviour and knowledge. The report shows that the prevalence of STIs or symptoms of STIs in 5 Southeast Asian (SEA) countries included in the study is 11.6%, with the highest prevalence found in Cambodia, and the lowest in Philippines. Women aged 15-24 years in Indonesia (17.08%) and Philippines (9.81%), had a higher risk of STIs than those aged 25-49 years. In most studied countries of SEA (Cambodia, Indonesia and Myanmar), poorer women had higher risk of STIs. Also, in most SEA countries (Cambodia, Indonesia, and the Philippines), knowledge of STIs was significantly associated with having an STI in women aged 15-49 years. Sexual behaviour factors showed that acceptance of beating a wife for refusing to have sex with her husband was associated with STIs in all countries except Myanmar. The association between women's characteristics in reproductive age including socio-demography, sexual knowledge and behaviour, and STIs or symptoms of STIs is varied in countries of SEA. STIs interventions can be tailored to the specific characteristics of women in each of the 5 countries of SEA.

Provincial distribution and factors associated with self-reported sexually transmitted infections and their symptoms among women in Sierra Leone

BACKGROUND

Sexually transmitted infections (STIs) are a significant public health concern worldwide. These infections can have severe consequences for women's health, including pelvic inflammatory disease, infertility, and increased risk of HIV acquisition. Understanding the prevalence and factors associated with STIs among women in Sierra Leone is crucial to developing effective prevention and treatment strategies. This study investigated the provincial distribution and factors associated with self-reported STIs (SR-STIs) and STI symptoms among women in Sierra Leone.

METHODS

The study used data from the 2019 Sierra Leone Demographic and Health Survey, comprising 13,965 women aged 15 to 49 who have ever had sex. Provincial variations in the prevalence of SR-STIs and STI symptoms were presented using a spatial map. A binary logistic regression analysis was performed to assess the factors associated with SR-STIs and STI symptoms among women in Sierra Leone. The results were presented as adjusted odds ratios (aOR) with a 95% confidence interval (CI).

RESULTS

The overall prevalence of SR-STIs and their symptoms was 21.6% [20.4, 22.9] among women in Sierra Leone. Higher odds of SR-STIs and their symptoms were associated with being aged 25-29 (aOR = 1.35, 95% CI = 1.10,1.66), 30-34 (aOR = 1.38, 95% CI = 1.09,1.74), 35-39 (aOR = 1.39, 95% CI = 1.10, 1.77), having tested for HIV (aOR = 1.16, 95% CI = 1.04, 1.29), and having multiple sexual partners (aOR = 2.25, 95% CI = 1.80, 2.83) compared to those in the reference category. Being in the rich wealth index (aOR = 1.32, 95% CI = 1.11, 1.57), living in the Northern (aOR = 2.43, 95% CI = 2.08, 2.83) and Northwestern province (aOR = 3.28, 95% CI = 2.81, 3.83), and being covered by health insurance (aOR = 3.19, 95% CI = 2.62, 3.88) were associated with higher odds of SR-STIs and their symptoms. Lower odds of SR-STIs and their symptoms were found among women with one (aOR = 0.81, 95% CI = 0.68, 0.96), two (aOR = 0.75, 95% CI = 0.61, 0.93), three (aOR = 0.66, 95% CI = 0.53, 0.83), and four or more children (aOR = 0.62, 95% CI = 0.49, 0.77], those residing in rural areas (aOR = 0.81, 95% CI = 0.69, 0.94), and women living in the Southern province (aOR = 0.67, 95% CI = 0.57, 0.80) compared to those in the reference category.

CONCLUSION

The findings indicate that SR-STIs and their symptoms are prevalent among women in Sierra Leone. Our findings underscore the urgent need for targeted public health interventions to address the SR-STIs and their symptoms among women in Sierra Leone. The increased risk among women aged 25-39, those with multiple sexual partners and those from wealthier backgrounds, suggests that educational programmes focusing on safe sexual practices and STI prevention should be prioritized in urban and affluent areas. Additionally, the lower odds of SR-STIs among women with more children and those in rural regions indicate that family dynamics and geographic factors may offer protective benefits, which could be leveraged in public health messaging. Our findings highlight the importance of tailoring health services and outreach efforts to effectively reach and support vulnerable populations, ultimately aiming to reduce the incidence of SR-STIs.

Antepartum Intimate Partner Violence: Development of a Risk Prediction Model

Objectives: To explore socio-behavioral, clinical, and imaging findings associated with antepartum intimate partner violence (IPV) and aid in risk stratification of at-risk individuals. Methods: We analyzed electronic medical records during indexed pregnancies for 108 pregnant patients who self-reported antepartum IPV (cases) and 106 age-matched pregnant patients who did not self-report antepartum IPV (controls). Sociodemographic, clinical, and radiology data were analyzed via chi-squared and Fisher's exact tests with p < 0.05 as the threshold for significance. Stepwise logistic regression was applied to derive a risk prediction model. Results: The proportion of cases reporting emotional IPV (76% vs. 52%) and/or physical IPV (45% vs. 31%) during pregnancy significantly increased from prior to pregnancy. Cases were significantly more likely to report prepregnancy substance use (odds ratio [OR] = 2.60; 95% confidence interval [CI]: 1.13-5.98), sexually transmitted infections (OR = 3.48; 95%CI: 1.64-7.37), abortion (OR = 3.17; 95%CI: 1.79, 5.59), and preterm birth (OR = 5.97; 95%CI: 1.69-21.15). During pregnancy, cases were more likely to report unstable housing (OR = 5.26; 95%CI: 2.67-10.36), multigravidity (OR = 2.83; 95%CI: 1.44-5.58), multiparity (OR = 3.75; 95%CI: 1.72-8.20), anxiety (OR = 3.35; 95%CI: 1.85-6.08), depression (OR = 5.58; 95%CI: 3.07-10.16), substance use (OR = 2.92; 95%CI: 1.28-6.65), urinary tract infection (UTI) (OR = 3.26; 95%CI: 1.14-9.32), intrauterine growth restriction (OR = 10.71; 95%CI: 1.35-85.25), and cesarean delivery (OR = 2.25; 95%CI: 1.26-4.02). Cases had significantly more OBGYN abnormalities on imaging and canceled more radiological studies (OR = 5.31). Logistic regression found housing status, sexually transmitted infection history, preterm delivery history, abortion history, depression, and antepartum UTI predictive of antepartum IPV. The risk prediction model achieved good calibration with an area under the curve of 0.79. Conclusions: This study identifies significant disparities among patients experiencing antepartum IPV, and our proposed risk prediction model can inform risk assessment in this setting.

Sex Disparities in Chlamydia and Gonorrhea Treatment in US Adult Emergency Departments: A Systematic Review and Meta-analysis

Importance

In US emergency departments (EDs), empiric antibiotic treatment for gonorrhea (GC) and chlamydia (CT) is common due to the unavailability of immediate test results. Evidence suggests sex-based disparities in treatment practices, with females potentially receiving less empiric treatment than males.

Objective

To investigate sex differences in empiric antibiotic treatment for GC and CT in EDs, comparing practices to subsequent laboratory-confirmed results.

Design Setting and Participants

This systematic review and meta-analysis included studies from US EDs reporting GC/CT testing and empiric antibiotic treatment from January 2010 to February 2021. A total of 1,644 articles were screened, with 17 studies (n = 31,062 patients) meeting inclusion criteria.

Main Outcomes and Measures

The primary outcomes were GC/CT test positivity, empiric antibiotic treatment rates, and discordance between treatment and test results, stratified by sex. Data were analyzed using a random-effects model.

Results

Overall GC/CT positivity was 14% (95% CI, 11%-16%): 11% (95% CI, 8%-14%) in females and 25% (95% CI, 23%-26%) in males. Empiric antibiotic treatment was administered in 46% (95% CI, 38%-55%) of cases: 31% (95% CI, 24%-37%) in females and 73% (95% CI, 65%-80%) in males. Among patients without a laboratory-confirmed infection, 38% (95% CI, 30%-47%) received treatment: 27% (95% CI, 20%-34%) of females and 64% (95% CI, 55%-73%) of males. Conversely, 39% (95% CI, 31%-48%) of patients with laboratory-confirmed infections were not treated: 52% (95% CI, 46%-57%) of females and 15% (95% CI, 12%-17%) of males.

Conclusions and Relevance

There is significant discordance between ED empiric antibiotic treatment and laboratory-confirmed results, with notable sex-based disparities. Females were 3.5 times more likely than males to miss treatment despite confirmed infection. These findings highlight the need for improved strategies to reduce sex-based disparities and enhance empiric treatment accuracy for GC/CT in ED settings.

Key Points

Question: Are there sex-based differences in empiric antibiotic treatment for gonorrhea and chlamydia in US emergency departments (EDs), and how do these practices compare to laboratory-confirmed results?Findings: In this systematic review and meta-analysis of 17 studies with 31,062 patients, females were significantly less likely than males to receive empiric antibiotic treatment for gonorrhea and chlamydia. Additionally, 39% of patients with a laboratory-confirmed infection were not empirically treated, with females 3.5 times more likely to miss treatment than males.Meaning: The findings indicate significant sex disparities in ED empiric antibiotic treatment for sexually transmitted infections, underscoring the need for improved strategies to ensure equitable and accurate treatment across sexes.

Evaluating Chlamydia trachomatis and Neisseria gonorrhoeae screening and treatment among asymptomatic pregnant women to prevent preterm birth and low birthweight in Gaborone, Botswana: A secondary analysis from a non-randomised, cluster-controlled trial

OBJECTIVE

To evaluate the impact of screening and treating asymptomatic pregnant women for Chlamydia (C.) trachomatis and Neisseria (N.) gonorrhoeae infections on the frequency of preterm birth or low birthweight infants in Botswana.

DESIGN

Non-randomised, cluster-controlled trial.

SETTING

Four antenatal care clinics in Gaborone, Botswana.

POPULATION

Pregnant women aged ≥15 years, attending a first antenatal care visit, ≤27 weeks of gestation and without urogenital symptoms were eligible.

METHODS

Participants in the intervention clinics received screening (GeneXpert®, Cepheid) during pregnancy and at the postnatal visit. Participants in the standard-of-care clinics received screening at the postnatal visit only. We used multivariable logistic regression and post-estimation predictive margins analysis. Post-hoc analysis was conducted among sub-samples stratified by parity.

MAIN OUTCOME MEASURES

Preterm birth (<37 weeks of gestation) and low birthweight (<2500 g).

RESULTS

After controlling for parity, hypertension, antenatal care visits and clinic site, the predicted prevalence of preterm birth or low birthweight was lower in the intervention arm (11%) compared with the standard-of-care arm (16%) (adjusted odds ratio [aOR] 0.59; 95% confidence interval [CI] 0.28-1.24). In post-hoc analysis, the intervention was more effective than the standard-of-care (aOR 0.20; 95% CI 0.07-0.64) among nulliparous participants.

CONCLUSION

A C. trachomatis and N. gonorrhoeae infection screening and treatment intervention among asymptomatic pregnant women may have reduced preterm birth or low birthweight outcomes, but results were not statistically significant. Post-hoc analysis found that the intervention reduced adverse outcomes among nulliparous participants.

The association between non-viral sexually transmitted infections and pregnancy outcome in Latin America and the Caribbean: A systematic review

Introduction

Non-viral sexually transmitted infections are known to be associated with adverse pregnancy outcomes. For these pathogens, standard antenatal screening is not broadly performed in Latin America and the Caribbean. The aim of this study was to comprehensively review the association of non-viral sexually transmitted infections and neonatal outcomes among pregnant women in the region.

Methods

Four databases (PubMed, Embase, SciELO and LILACS) were examined to identify eligible studies published up to September 2022. English or Spanish cross-sectional, case-control and cohort studies assessing the association of non-viral sexually transmitted infections and adverse pregnancy outcomes were evaluated. Articles were firstly screened by means of title and abstract. Potential articles were fully read and assessed for inclusion according to the eligibility criteria. Snowballing search was performed by screening of bibliographies of the chosen potentially relevant papers. Risk of bias within studies was assessed using the Joanna Briggs Institute reviewer's manual.

Results

A selection of 10 out of 9772 search records from five Latin America and the Caribbean countries were included. Six studies associated Treponema pallidum infection with preterm birth (1/6), history of previous spontaneous abortion (2/6), fetal and infant death (1/6), low birth weight (1/6) and funisitis of the umbilical cord (1/6). Three studies associated Chlamydia trachomatis infection with preterm birth (2/3), ectopic pregnancy (1/3) and respiratory symptoms on the newborn (1/3). One study associated Mycoplasma genitalium infection with preterm birth.

Conclusion

This review provides evidence on the association of non-viral sexually transmitted infections with adverse pregnancy outcomes. Further investigation is needed to establish more associations between non-viral sexually transmitted infections and pregnancy outcome, especially for Mycoplasma genitalium, Trichomonas vaginalis and Neisseria gonorrhoeae. Overall, this review calls for more research for public health interventions to promote screening of non-viral sexually transmitted infections during pregnancy, among high-risk population groups of pregnant women living in the region.

Highly-Specific Single-Stranded Oligonucleotides and Functional Nanoprobes for Clinical Determination of Chlamydia Trachomatis and Neisseria Gonorrhoeae Infections

Early detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) is the key to controlling the spread of these bacterial infections. An important step in developing biosensors involves identifying reliable sensing probes against specific genetic targets for CT and NG. Here, the authors have designed single-stranded oligonucleotides (ssDNAs) targeting mutually conserved genetic regions of cryptic plasmid and chromosomal DNA of both CT and NG. The 5'- and 3'- ends of these ssDNAs are differentially functionalized with thiol groups and coupled with gold nanoparticles (AuNP) to develop absorbance-based assay. The AuNPs agglomerate selectively in the presence of its target DNA sequence and demonstrate a change in their surface plasmon resonance. The optimized assay is then used to detect both CT and NG DNA extracted from 60 anonymized clinical samples with a clinical sensitivity of ∼100%. The limit of detection of the assays are found to be 7 and 5 copies/µL for CT and NG respectively. Furthermore, it can successfully detect the DNA levels of these two bacteria without the need for DNA extraction and via a lateral flow-based platform. These assays thus hold the potential to be employed in clinics for rapid and efficient monitoring of sexually transmitted infections.

The association between adverse pregnancy outcomes and non-viral genital pathogens among women living in sub-Saharan Africa: a systematic review

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.

Multiple sexually transmitted co-infections are associated with adverse reproductive outcomes in asymptomatic adolescent pregnant women; A Prospective cohort study

BACKGROUND

A prospective cohort was conducted to assess the prevalence of seven RTIs/STIs in adolescent asymptomatic pregnant women to find a significant correlation between infection and pregnancy.

METHODS

The study was restricted to 18-19 years of asymptomatic adolescent pregnant women attending Ante-Natal Care and the health status of the pregnant women were followed up to parturition. The health status of the infant was followed till 6 months post-delivery. The prevalence of the concerning pathogens and the significance of their association with adverse outcomes of pregnancy were determined.

RESULTS

Among 279 subjects, the most significant co-infections were observed for M. hominis with U. parvum (9.31%; p-value-0.0071/OR-2.6421) and U. urealyticum (7.88%; p-value-0.0119/OR-2.6455). Statistically significant associations were found between C. trachomatis [(p-value-0.0439); OR-2.9902] and M. genitalium [(p-value-0.0284); OR-3.442] with PTB, N. gonorrhoeae with LBW <2.5 kg [(p-value-0.0052);OR-4.9017], U. urealyticum with VLBW <2 kg [(p-value-0.0262);OR-3.0207], M. genitalium [(p-value-0.0184); OR-11.7976] and T. vaginalis with PROM [(p-value 0.0063); OR-19.4275] while M. genitalium [(p-value 0.0190); OR-12.9230] and U. urealyticum [(p-value 0.0063); OR-14.5149] with PPROM with 95% CI respectively.

CONCLUSIONS

Asymptomatic adolescents are at high risk of adverse pregnancy outcomes if infected with the concerned pathogens.

Prevalence of syphilis and chlamydia trachomatis infection among men who have sex with men in Jiangsu province, China: A cross-sectional survey

Background

Epidemics of sexually transmitted infections (STIs) among men who have sex with men (MSM) are major global public health concerns. This study aimed to examine the prevalence of syphilis and chlamydia trachomatis (CT) infection and associated factors among MSM in Jiangsu province, China, hoping to provide updated data for the formulation of relevant policies.

Methods

A cross-sectional survey was conducted among MSM from April to July 2021 in four cities in the province. Socio-demographic characteristics and behavioral information were collected through a face-to-face questionnaire interview. Venous blood specimens were collected for HIV, hepatitis C (HCV), and syphilis testing using serological testing methods. First-void urine specimens were collected for CT and Neisseria gonorrhoeae (NG) testing using nucleic acid amplification testing (NAAT) methods. Chi-square tests were used to compare differences in syphilis and CT infection between subgroups of variables. Multivariate logistic regression analysis was used to identify factors associated with syphilis and CT infection.

Results

A total of 1,087 participants were enrolled. The prevalence of HIV, HCV, syphilis, CT and NG infection were 6.6, 0.4, 6.3, 4.2, and 0.4%, respectively. MSM recruited online [adjusted odds ratio (aOR) = 2.189, P = 0.020], diagnosed with an STI in the past 12 months (aOR = 3.304, P < 0.001), and living with HIV (aOR = 4.721, P < 0.001) were more likely to have syphilis infection. MSM who were younger than 25 years (aOR = 4.286, P = 0.020), had senior high school level education (aOR = 2.521, P = 0.038), and were recruited via VCT clinics (aOR = 3.455, P = 0.001) were more likely to have CT infection.

Conclusions

Our study showed a high prevalence of syphilis and chlamydia among MSM in Jiangsu province, China. STI screening, diagnosis, and treatment services promotion should be a top priority on the prevention agenda.

Factors associated with testing for HIV and other sexually transmitted infections in men who have sex with men and transgender women in Bangkok, Thailand

Background

Routine screening for HIV and other sexually transmitted infections (STIs) facilitates early diagnosis and treatment, thereby preventing morbidity and onward transmission. We estimated the prevalence of prior HIV/STI testing among men who have sex with men (MSM) and transgender women (TGW) in Bangkok, Thailand, and identified factors associated with prior testing.

Methods

Cross-sectional analyses were performed using data collected at enrollment into an HIV incidence cohort. From April to October 2017, MSM and TGW were enrolled if they were aged 18–35 years, reported anal intercourse with a male or TGW partner, and reported behavioral vulnerability to HIV. Participants answered questions about demographics, sexual behaviors, and lifetime HIV/STI testing history. Multivariable robust Poisson regression was used to estimate risk ratios (RRs) and 95% confidence intervals (CIs) for factors potentially associated with prior testing.

Results

Among 1,014 participants, 348 (34.3%) were TGW and the median age was 21.6 (interquartile range 20.0-24.8) years. Prior testing for HIV was reported by 421 (41.5%) and for other STIs by 268 (26.4%). HIV testing was more common among participants aged ≥ 22 years (RR 1.37 [95% CI 1.13–1.67]), with college education as compared to secondary or less (RR 1.37 [95% CI 1.08–1.72]), and who met male sexual partners online (RR 1.52 [95% CI 1.24–1.85]), but lower among participants attracted to both men and women as compared to men only (RR 0.64 [95% CI 0.51–0.81]) and who met male sexual partners in bars (RR 0.83 [95% CI 0.72–0.97]). Similar associations were observed with prior testing for other STIs, including increased testing among participants with college education (RR 1.52 [95% CI 1.11–2.09]) and who met male sexual partners online (RR 1.73 [95% CI 1.30–2.31]), but lower among participants attracted to both men and women (RR 0.70 [95% CI 0.51–0.96]) and who met male sexual partners in bars (RR 0.67 [95% CI 0.54–0.83]).

Conclusions

Despite behavioral vulnerability, prior testing for HIV and other STIs was uncommon. Online engagement strategies may be effectively reaching Thai MSM and TGW who meet sexual partners online, but new interventions are needed to encourage testing among younger, less educated, and bisexual MSM and TGW.

Sexually transmitted infections in pregnant women from sub-Saharan Africa

Background

Sexually transmitted infections (STIs) are a major health problem in most countries of the world, particularly in developing countries where the resources and technology to diagnose and treat them are limited. Currently, there is limited data on STIs and risk factors for these infections in pregnant women living with human immunodeficiency virus (HIV), especially in sub-Saharan Africa (SSA). This review provides data on the prevalence and risk factors for STIs in pregnant women living with HIV from SSA. This review also describes the association between STIs and HIV on pregnancy and birth outcomes as well as highlights the importance of laboratory-based diagnosis of STIs.

Method

An electronic search of online databases was used to find and collect relevant research articles connected to the prevalence, adverse pregnancy and birth outcomes, health complications and risk factors associated with STIs and HIV in pregnant women from SSA. The search was limited to articles published in English. Relevant studies were identified by searching literature from January 2001 to date. The search yielded 4709 results.

Results

In SSA, STIs are highly prevalent in pregnant women and are widely known to be linked with an increased risk of poor maternal and neonatal outcomes. These infections are often asymptomatic and highly prevalent in pregnant women. The screening of STIs in pregnant women living with HIV can reduce the risk of mother-to-child transmission (MTCT) and screening and treatment for STIs can also prevent adverse perinatal outcomes. It is important to recognise regional and national STI epidemics in order to promote STI prevention and control interventions considering the test and treat approach as opposed to syndromic management.

Conclusion

This review highlights the need to use diagnostic screening methods instead of syndromic STI management in SSA. Moreover, more research into effective prevention and treatment measures for STIs in pregnant women is urgently required.

High prevalence of Chlamydia trachomatis infection among women attending STD and gynecology clinics in Jiangsu province, China: A cross-sectional survey

Epidemics of Chlamydia trachomatis (CT) infection among women are major global public health concerns. This study examined the prevalence of CT infection and associated factors among women attending sexually transmitted disease (STD) and gynecology clinics in Jiangsu province, China.A cross-sectional survey was conducted among women attending STD and gynecology clinics in the province during 2018 to 2019. Socio-demographic and behavioral information were collected through face-to-face questionnaire survey. Cervical swab specimens were collected to test for CT. Chi square tests were used to compare differences in CT prevalence between subgroups of characteristics. Multivariate logistic regression analysis was used to identify factors associated with CT infection.A total of 2664 participants were enrolled. The prevalence of CT infection was 16.6% (95% confidence interval: 15.0%-18.1%). Of those, CT prevalence among participants from STD clinics (19.4%) and South Jiangsu (18.5%) were higher. Female outpatients who were service personnel (adjusted odds ratio [aOR] = 1.667, P = .004) or farmers (aOR = 1.593, P = .039), lived in South Jiangsu (aOR = 1.796, P = .004), and were from STD clinics (aOR = 1.608, P = .022) were more likely to infect CT.Our study showed a high prevalence of CT infection among women attending STD and gynecology clinics in Jiangsu province, China. CT screening, surveillance and treatment promotion should therefore be of top priority on the CT prevention agenda.

Vaginal Microbiota of the Sexually Transmitted Infections Caused by Chlamydia trachomatis and Trichomonas vaginalis in Women with Vaginitis in Taiwan

The three most common sexually transmitted infections (STIs) are Chlamydia trachomatis (CT), Neisseria gonorrhoeae (GC) and Trichomonas vaginalis (TV). The prevalence of these STIs in Taiwan remains largely unknown and the risk of STI acquisition affected by the vaginal microbiota is also elusive. In this study, a total of 327 vaginal swabs collected from women with vaginitis were analyzed to determine the presence of STIs and the associated microorganisms by using the BD Max CT/GC/TV molecular assay, microbial cultures, and 16S rRNA sequencing. The prevalence of CT, TV, and GC was 10.8%, 2.2% and 0.6%, respectively. A culture-dependent method identified that Escherichia coli and Streptococcus agalactiae (GBS) were more likely to be associated with CT and TV infections. In CT-positive patients, the vaginal microbiota was dominated by L. iners, and the relative abundance of Gardnerella vaginalis (12.46%) was also higher than that in TV-positive patients and the non-STIs group. However, Lactobacillus spp. was significantly lower in TV-positive patients, while GBS (10.11%), Prevotella bivia (6.19%), Sneathia sanguinegens (12.75%), and Gemella asaccharolytica (5.31%) were significantly enriched. Using an in vitro co-culture assay, we demonstrated that the growth of L. iners was suppressed in the initial interaction with TV, but it may adapt and survive after longer exposure to TV. Additionally, it is noteworthy that TV was able to promote GBS growth. Our study highlights the vaginal microbiota composition associated with the common STIs and the crosstalk between TV and the associated bacteria, paving the way for future development of health interventions targeting the specific vaginal bacterial taxa to reduce the risk of common STIs.

Self-reported syndromes of sexually transmitted infections and its associated factors among reproductive (15-49 years) age women in Ethiopia

Background

Sexually Transmitted Infections (STIs) are among the most important causes of maternal and neonatal morbidity and mortality. It remains a significant public health problem and disproportionately affects women posing a large public health burden in low and middle-income countries. However, there is little information on the magnitude of self-reported syndromes of STIs among reproductive-age women in Ethiopia.

Aim

This study aimed to determine the magnitude of self-reported syndromes of sexual transmitted infections and its associated factors among women of reproductive age in Ethiopia.

Methods

The study was based on the data from the Ethiopian Demographic Health Survey of 2016. The data on the status of self-reported STIs were extracted from the individual women dataset, and a total of 15,683 reproductive-age women were involved in the study. Since the data has a hierarchical and cluster nature sampling weight was applied for all analysis procedures to account for complex survey design. Rao-scot chi-square test that adjusts for complex sample design was used to examine the association of outcome and independent variables. In, multivariable analysis, the level of statistical significance was declared at P-value ≤ 0.05.

Findings and conclusions

The magnitude of self-reported STIs was 3.0 % (95% CI: 2.92–3.08). Among self-reported syndromes of STIs only, 33.3 % (158) seek care for sexually transmitted infections. Age (Adjusted Odds Ratio (AOR = 2.15; 95%CI:1.4, 3.4)), marital status (AOR = 1.72; 95%CI:1.02, 2.90), women attending higher education and above (AOR = 2.67; 95%CI:1.57,4.57), history of termination of pregnancy (AOR = 2.85; 95%CI:2.0,4.08), and risky sexual behavior (AOR = 1.72; 95%CI:1.02,2.90) were found to be associated with self-reported syndrome of sexually transmitted infections. The magnitude of self-reported syndromes of STI and health care seeking behaviors among reproductive-age women was found low. Therefore, the government should enhance the awareness of women for sexually transmitted syndromes, and increase accessibility of STI services. Moreover, qualitative studies should be done to identify the demand, supply, and barriers related to STI among women of reproductive age women in Ethiopia.

Exploring modifiable risk-factors for premature birth in the context of COVID-19 mitigation measures: A discussion paper

During the COVID-19 pandemic, parents with sick or premature babies have faced challenges following admission to a neonatal unit due to the imposed lock-down restrictions on social contact, hospital visitation and the wearing of personal protective equipment. The negative short-term impact on neonatal care in relation to the prevention of close proximity, contact and bonding between parents and babies is potentially significant. However, an interesting finding has been reported of a reduction in premature birth admissions to the neonatal intensive care unit during the pandemic, raising important questions. Why was this? Was it related to the effect of the modifiable risk-factors for premature birth? This discussion paper focuses on an exploration of these factors in the light of the potential impact of COVID-19 restrictions on neonatal care. After contextualising both the effect of premature birth and the pandemic on neonatal and parental short-term outcomes, the discussion turns to the modifiable risk-factors for premature birth and makes recommendations relevant to the education, advice and care given to expectant mothers.

Introduction of a complementary screening system for the detection of sexually transmitted infections in patients with sterile pyuria

Objective

The aim of the study was to evaluate a complementary screening system for the detection of sexually transmitted infections in patients with sterile pyuria.

Material and methods

A prospective study was conducted using Real-time multiplex qPCR in 300 consecutive urine samples with data on sterile pyuria. STI prevalence and patient epidemiological data were analyzed.

Results

A total of 29 positive cases (9.67%) were found: 16 Chlamydia trachomatis, 5 Mycoplasma genitalium, 5 Trichomonas vaginalis and 3 co-infections. The group with sexually transmitted infections was mainly composed of women (65.5%), of which one third was pregnant.

Conclusion

This study presents an effective screening system for the detection of sexually transmitted infections that can be integrated into the laboratories’ work routine.

Prevalence, risk factors and association with delivery outcome of curable sexually transmitted infections among pregnant women in Southern Ethiopia

INTRODUCTION

Curable sexually transmitted infections (STIs) such as infection with Chlamydia trachomatis (C. trachomatis), Neisseria gonorrhoeae (N. gonorrhoeae), and Trichomonas vaginalis (T. vaginalis) can lead to adverse pregnancy and birth outcome. There are limited data on the prevalence and correlate of STI in Ethiopia, yet pregnant women are not screened for curable STI. Hence in this study, the prevalence of STIs and associated risk factors were assessed.

METHODOLOGY

A cross- sectional study was conducted on consecutive women attending the delivery ward at the Hawassa comprehensive and specialized hospital. Vaginal swabs collected at the time of labor and delivery were tested for C. trachomatis, N. gonorrhoeae and T. vaginalis using GeneXpert. Study participants responded to a questionnaire about their previous and current obstetric history and socio-demographic characteristics. Possible independent factors for curable STIs were assessed by chi-square, bivariable, and multivariable, logistic regression.

RESULTS

Of the 350 vaginal swabs tested, 51 (14.6%, 95% CI: 10.9-18.3) were positive for one or more curable STIs. The prevalence of C. trachomatis, N. gonorrhoeae and T. vaginalis were 8.3%, 4.3%, and 3.1%, respectively. STIs was associated (p<0.005) with the delivery outcomes birth weight and gestational age. A 3-fold increase in odds of acquisition STIs was found in currently unmarried women (AOR, 3.5; 95% CI: 1.1-10.4; p = 0.028), in women <25 years (AOR, 2.7; 95% CI 1.1-6.6; p = 0.031). Women reporting presence of vaginal discharge (AOR, 7.7; 95% CI: 3.2-18.6; p < 0.001) and reporting pain during urination (AOR, 6.5; 95% CI: 2.6-16.2; p <0.001) found to associate with curable STIs.

CONCLUSION

The higher magnitude of STIs found in this population, and the absence of symptoms in many illustrate the need for systematic follow-up during routine antenatal care primarily history taking and asking for signs and symptoms to provide early management and avoid long term sequelae.

Adverse pregnancy and neonatal outcomes associated with Neisseria gonorrhoeae: systematic review and meta-analysis

Objective

To examine associations between Neisseria gonorrhoeae (NG) infection during pregnancy and the risk of preterm birth, spontaneous abortion, premature rupture of membranes, perinatal mortality, low birth weight and ophthalmia neonatorum.

Data sources

We searched Medline, EMBASE, the Cochrane Library and Cumulative Index to Nursing and Allied Health Literature for studies published between 1948 and 14 January 2020.

Methods

Studies were included if they reported testing for NG during pregnancy and compared pregnancy, perinatal and/or neonatal outcomes between women with and without NG. Two reviewers independently assessed papers for inclusion and extracted data. Risk of bias was assessed using established checklists for each study design. Summary ORs with 95% CIs were generated using random effects models for both crude and, where available, adjusted associations.

Results

We identified 2593 records and included 30 in meta-analyses. Women with NG were more likely to experience preterm birth (OR 1.55, 95% CI 1.21 to 1.99, n=18 studies); premature rupture of membranes (OR 1.41, 95% CI 1.02 to 1.92, n=9); perinatal mortality (OR 2.16, 95% CI 1.35 to 3.46, n=9); low birth weight (OR 1.66, 95% CI 1.12 to 2.48, n=8) and ophthalmia neonatorum (OR 4.21, 95% CI 1.36 to 13.04, n=6). Summary adjusted ORs were, for preterm birth 1.90 (95% CI 1.14 to 3.19, n=5) and for low birth weight 1.48 (95% CI 0.79 to 2.77, n=4). In studies with a multivariable analysis, age was the variable most commonly adjusted for. NG was more strongly associated with preterm birth in low-income and middle-income countries (OR 2.21, 95% CI 1.40 to 3.48, n=7) than in high-income countries (OR 1.38, 95% CI 1.04 to 1.83, n=11).

Conclusions

NG is associated with a number of adverse pregnancy and newborn outcomes. Further research should be done to determine the role of NG in different perinatal mortality outcomes because interventions that reduce mortality will have the greatest impact on reducing the burden of disease in low-income and middle-income countries.

Point-of-Care Testing for Sexually Transmitted Infections: A Review of Recent Developments

CONTEXT.—

Sexually transmitted infections (STIs) are among the most common communicable diseases globally and are associated with significant morbidity and mortality worldwide. Point-of-care tests have the potential to revolutionize the prevention and control of STIs by enabling rapid diagnosis and early treatment of infections, thus interrupting transmission and preventing the sequelae of untreated infections. Currently, there are several point-of-care (POC) tests available for the diagnosis of Treponema pallidum, Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis infections, although these tests differ with regard to their performance, turnaround time, and cost.

OBJECTIVE.—

To provide an updated review of the POC tests available and under development for the diagnosis of T pallidum, C trachomatis, N gonorrhoeae, and T vaginalis infections, to discuss the context for which these tests might be used, and to highlight future directions for test development.

DATA SOURCES.—

We reviewed the literature pertaining to the recent development and performance evaluations of POC tests for the diagnosis of syphilis, chlamydia, gonorrhea, and trichomonas.

CONCLUSIONS.—

Recently, there has been rapid development of new POC tests for STIs. Although there are inexpensive, rapid, and accurate POC tests available for syphilis, there are few such tests available for the diagnosis of chlamydia, gonorrhea, or trichomonas, and currently none with the ability to detect antimicrobial resistance in N gonorrhoeae. Research evaluating implementation strategies for the currently available tests and the development of additional POC tests that are rapid, accurate, and affordable are urgently needed to address the rising number of STIs worldwide.

A review of prenatal HIV screening practices among physicians at a tertiary care center in Lebanon: is it culture?

HIV remains one of the major causes of mortality and morbidity among women of reproductive age; given the risk of vertical transmission to the fetus, timely prevention, monitoring and management are imperative (Melaku et al. [2014]. Causes of death among females-investigating beyond maternal causes: A community-based longitudinal study. BMC Research Notes, 7(1), 629. https://doi.org/10.1186/1756-0500-7-629). Most HIV studies in Lebanon focus on men who have sex with men, people diagnosed with sexually transmitted infections, intravenous (IV) drug users, and people infected by blood transfusion products Ministry of Public Health [2017]. National AIDS Control Program in Lebanon. https://www.moph.gov.lb/en/Pages/2/4000/aids#/en/Pages/2/4000/aids; Shaheen [2014]. Around 3,750 HIV/AIDS cases in Lebanon. The Daily Star. https://www.dailystar.com.lb/News/Lebanon-News/2014/Dec-02/279570-around-3750-hivaidscases-in-lebanon.ashx). We conducted a retrospective review of women who delivered at a tertiary academic hospital in Beirut between January 2016-Decemeber 2017 to assess prenatal HIV screening practices. In total, 1500 charts were randomly selected and reviewed: 137 (9%) women were screened for HIV, 2 (1.5%) tested positive. Odds rations were calculated for screening in relation to religion, parity, previous abortions, and mode of delivery: none were significant. No one was tested for Gonorrhoea and Chlamydia; 1250 (93.8%) were tested for Hepatitis B, 27 (1.9%) for Hepatitis C, 7 (0.5%) for HSV and, 74(5.3%) for Syphilis. Barriers to screening may include: Lack of consensus on mandated screening policy, HIV stigma, physician and patient prejudice and misconception of risk and, financial barriers as health insurance does not cover HIV screening.
