RESUMEN
STI prophylaxis using doxycycline is discussed internationally for persons at high risk of STIs (Doxy-PEP). Doxy-PEP would probably have limited effect on gonorrhoea due to resistance to tetracyclines. Doxy-PEP may reduce the incidence of chlamydia and syphilis, but would not reduce the number of complicated infections. Further studies are needed on the effects of intermittent antibiotic use on the microbiome or antibiotic resistance in general.

BACKGROUND: Acquired syphilis continues to affect millions of people around the world. It is crucial to study it in the context of HIV Pre-Exposure Prophylaxis (PrEP) to achieve the goals set out in the 2030 Agenda since the literature suggests increased risk behaviors for sexually transmitted infections. This study aimed to investigate the incidence and factors associated with acquired syphilis among PrEP users. MATERIALS AND METHODS: This retrospective cohort included data on PrEP users from all over Brazil from 2018 to 2020, retrieved from the national antiretroviral logistics system. We calculated the proportion of syphilis before PrEP, the incidence during the user's follow-up, reinfections, and their possible associated factors. We conducted descriptive, bivariate, and multivariate analysis, estimating the crude Relative Risk, adjusted Odds Ratio (aOR), and their respective confidence intervals (95%CI). RESULTS: Most of the 34,000 individuals who started PrEP were male (89.0%), white (53.7%), self-identified as male (85.2%), homosexual, gay, or lesbian (72.2%), and had 12 schooling years or more (67.8%). Of these, 8.3% had syphilis in the six months before starting PrEP, and 4% had it in the first 30 days of using the prophylaxis. We identified a loss-to-follow-up rate of 41.7%, although the loss and the cohort shared similar characteristics. The proportion of missed syphilis tests was high: 33.4% in the 30 days and 38.8% in the follow-up period. In the 19,820 individuals effectively monitored, the incidence of acquired syphilis was 19.1 cases per 100 person-years, and 1.9% of users had reinfection. The rate of missed syphilis tests at the 30-day follow-up was 33.4%, and the total follow-up test period was 38.8%. The multivariate analysis identified female gender (aOR 0.3; 95%CI 0.2-0.5), being white or Black (aOR 0.9; 95%CI 0.7-0.9 and aOR 0.7; 95%CI 0.7-0.99, respectively) as protective factors for syphilis. Being homosexual, gay, lesbian (aOR 2.7; 95%CI 2.0-3.7), or having a history of syphilis in the six months before PrEP (aOR 2.2; 95%CI 1.9-2.5) were risk factors for syphilis during PrEP use. Behaviors related to the risk of syphilis included accepting something in exchange for sex (aOR 1.6; 95%CI 1.3-1.9), irregular condom use (use in less than half of sexual intercourse sessions; aOR 1.7; 95%CI 1.53-2.1) and recreational drug use (poppers; aOR 1.5; 95%CI 1.53-2.1). CONCLUSION: Syphilis in the context of PrEP has high rates and is associated with sociodemographic and behavioral factors. We recommend additional studies targeting prevention in this population to curb these figures.

BACKGROUND: Home-based sampling could create accessible testing opportunities for men who have sex with men (MSM) who use pre-exposure prophylaxis (PrEP). Blood collection is required for the most reliable laboratory results for HIV and syphilis testing. An innovative blood collection method (Tasso+) creates a vacuum and semi-automatically collects larger volumes of blood from the upper arm. This study aimed to assess acceptability and feasibility of this device among PrEP-using MSM and the performance of blood collection. METHODS: Between August 2022 and January 2023, 47 MSM were recruited during their routine PrEP consultations at a Dutch Centre for Sexual Health. Participants tested the method directly after consultation, and an online questionnaire determined acceptability and feasibility. Blood and residual serum volumes were measured after sampling and after HIV and syphilis testing. RESULTS: Of the participants, 87% had a positive attitude toward use of the device, and 77% would use it again for self-sampling at home. Participants rated the use of the blood collection device as easy (96%). On average, 536 µL whole blood (244 µL serum) was collected. All samples were tested for HIV and syphilis, and most samples had sufficient blood for routine HIV (91%) and syphilis testing (89%). Most samples (85%) had 220 µL residual blood, sufficient for further testing (e.g., confirmation). CONCLUSIONS: Blood self-sampling with a method that creates a vacuum from the upper arm is highly acceptable by users and performs well in blood collection for multiple tests. This method has promising potential for use in home-based sexual health care for PrEP-using MSM.

Introduction. ListerineÒ is a bactericidal mouthwash widely used to prevent oral health problems such as dental plaque and gingivitis. However, whether it promotes or undermines a healthy oral microbiome is unclear.Hypothesis/Gap Statement. We hypothesized that the daily use of Listerine Cool Mint would have a significant impact on the oropharyngeal microbiome.Aim. We aimed to assess if daily usage of Listerine Cool Mint influenced the composition of the pharyngeal microbiome.Methodology. The current microbiome substudy is part of the Preventing Resistance in Gonorrhoea trial. This was a double-blind single-centre, crossover, randomized controlled trial of antibacterial versus placebo mouthwash to reduce the incidence of gonorrhoea/chlamydia/syphilis in men who have sex with men (MSM) taking HIV pre-exposure prophylaxis (PrEP). Fifty-nine MSM taking HIV PrEP were enrolled. In this crossover trial, participants received 3 months of daily Listerine followed by 3 months of placebo mouthwash or vice versa. Oropharyngeal swabs were taken at baseline and after 3 months use of each mouthwash. DNA was extracted for shotgun metagenomic sequencing (Illumina Inc.). Non-host reads were taxonomically classified with MiniKraken and Bracken. The alpha and beta diversity indices were compared between baseline and after each mouthwash use. Differentially abundant bacterial taxa were identified using ANOVA-like differential expression analysis.Results. Streptococcus was the most abundant genus in most samples (n = 103, 61.7â%) with a median relative abundance of 31.5% (IQR 20.6-44.8), followed by Prevotella [13.5% (IQR 4.8-22.6)] and Veillonella [10.0% (IQR 4.0-16.8)]. Compared to baseline, the composition of the oral microbiome at the genus level (beta diversity) was significantly different after 3 months of Listerine (P = 0.006, pseudo-F = 2.29) or placebo (P = 0.003, pseudo-F = 2.49, permutational multivariate analysis of variance) use. Fusobacterium nucleatum and Streptococcus anginosus were significantly more abundant after Listerine use compared to baseline.Conclusion. Listerine use was associated with an increased abundance of common oral opportunistic bacteria previously reported to be enriched in periodontal diseases, oesophageal and colorectal cancer, and systemic diseases. These findings suggest that the regular use of Listerine mouthwash should be carefully considered.

BACKGROUND: Cost-effectiveness analyses have been conducted for many interventions for HIV/AIDS, malaria, syphilis, and tuberculosis, but they have not been conducted for all interventions that are currently recommended in all countries. To support national decision makers in the effective allocation of resources, we conducted a meta-regression analysis of published incremental cost-effectiveness ratios (ICERs) for interventions for these causes, and predicted ICERs for 14 recommended interventions for Global Fund-eligible countries. METHODS: In the meta-regression analysis, we used data from the Tufts University Center for the Evaluation of Value and Risk in Health (Boston, MA, USA) Cost-Effectiveness Registries (the CEA Registry beginning in 1976 and the Global Health CEA registry beginning in 1995) up to Jan 1, 2018. To create analysis files, we standardised and mapped the data, extracted additional data from published articles, and added variables from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD). Then we selected ratios for interventions with a minimum of two published articles and three published ICERs that mapped to one of five GBD causes (HIV/AIDS, malaria, syphilis, drug-susceptible tuberculosis, or multi-drug resistant tuberculosis), and to a GBD country; reported a currency year during or after 1990; and for which the comparator intervention was defined as no intervention, standard of care, or placebo. Our meta-regression analysis used all available data on 25 eligible interventions, and quantified the association between ICERs and factors at country level and intervention level. We used a five-stage statistical model that was developed to synthesise evidence on cost-effectiveness analyses, and we adapted it for smaller sample sizes by grouping interventions by cause and type (ie, prevention, diagnostics, and treatment). Using the meta-regression parameters we predicted country-specific median ICERs, IQRs, and 95% uncertainty intervals in 2019 US$ per disability-adjusted life-year (DALY) for 14 currently recommended interventions. We report ICERs in league tables with gross domestic product (GDP) per capita and country-specific thresholds. FINDINGS: The sample for the analysis was 1273 ratios from 144 articles, of which we included 612 ICERs from 106 articles in our meta-regression analysis. We predicted ICERs for antiretroviral therapy for prevention for two age groups and pregnant women, pre-exposure prophylaxis against HIV for two risk groups, four malaria prevention interventions, antenatal syphilis screening, two tuberculosis prevention interventions, the Xpert tuberculosis test, and chemotherapy for drug-sensitive tuberculosis. At the country level, ranking of interventions and number of interventions with a predicted median ICER below the country-specific threshold varied greatly. For instance, median ICERs for six of 14 interventions were below the country-specific threshold in Sudan, whereas 12 of 14 were below the country-specific threshold in Peru. Antenatal syphilis screening had the lowest median ICER among all 14 interventions in 81 (63%) of 128 countries, ranging from $3 (IQR 2-4) per DALY averted in Equatorial Guinea to $3473 (2244-5222) in Ukraine. Pre-exposure prophylaxis for HIV/AIDS for men who have sex with men had the highest median ICER among all interventions in 116 (91%) countries, ranging from $2326 (1077-4567) per DALY averted in Lesotho to $53â559 (23â841-108â534) in Maldives. INTERPRETATION: Country-specific league tables highlight the interventions that offer better value per DALY averted, and can support decision making at a country level that is more tailored to available resources than GDP per capita and country-specific thresholds. Meta-regression is a promising method to synthesise cost-effectiveness analysis results and transfer them across settings. FUNDING: Bill & Melinda Gates Foundation.

BACKGROUND: Partner notification (PN) is key to the control of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV). Digital interventions have been used to facilitate PN. A scoping review was conducted to describe the interventions used, user preferences and acceptability of digital PN interventions from patient and partner perspectives. METHODS: A systematic literature search was conducted of eight databases for articles published in English, available online with digital PN outcome data. Articles were assessed using the Mixed Methods Appraisal Tool. Quantitative and qualitative data were synthesised and analysed using thematic analysis. RESULTS: Twenty-six articles met the eligibility criteria. Articles were heterogeneous in quality and design, with the majority using quantitative methods. Nine articles focused solely on bacterial STIs (five on syphilis; four on chlamydia), one on HIV, two on syphilis and HIV, and 14 included multiple STIs, of which 13 included HIV. There has been a shift over time from digital PN interventions solely focusing on notifying partners, to interventions including elements of partner management, such as facilitation of partner testing and treatment, or sharing of STI test results (between index patients and tested sex partners). Main outcomes measured were number of partners notified (13 articles), partner testing/consultation (eight articles) and treatment (five articles). Relationship type and STI type appeared to affect digital PN preferences for index patients with digital methods preferred for casual rather than established partner types. Generally, partners preferred face-to-face PN. CONCLUSION: Digital PN to date mainly focuses on notifying partners rather than comprehensive partner management. Despite an overall preference for face-to-face PN with partners, digital PN could play a useful role in improving outcomes for certain partner types and infections. Further research needs to understand the impact of digital PN interventions on specific PN outcomes, their effectiveness for different infections and include health economic evaluations.

INTRODUCTION: Congenital syphilis (CS) is preventable through timely antenatal care (ANC), syphilis screening and treatment among pregnant women. Robust CS surveillance can identify gaps in this prevention cascade. We reviewed CS cases reported to the South African notifiable medical conditions surveillance system (NMCSS) from January 2020 to June 2022. METHODS: CS cases are reported using a case notification form (CNF) containing limited infant demographic and clinical characteristics. During January 2020-June 2022, healthcare workers supplemented CNFs with a case investigation form (CIF) containing maternal and infant testing and treatment information. We describe CS cases with/without a matching CIF and gaps in the CS prevention cascade among those with clinical information. FINDINGS: During January 2020-June 2022, 938 CS cases were reported to the NMCSS with a median age of 1 day (interquartile range: 0-5). Nine percent were diagnosed based on clinical signs and symptoms only. During January 2020-June 2022, 667 CIFs were reported with 51% (343) successfully matched to a CNF. Only 57% of mothers of infants with a matching CIF had an ANC booking visit (entry into ANC). Overall, 87% of mothers were tested for syphilis increasing to 98% among mothers with an ANC booking visit. Median time between first syphilis test and delivery was 16 days overall increasing to 82 days among mothers with an ANC booking visit. DISCUSSION: Only 37% of CS cases had accompanying clinical information to support evaluation of the prevention cascade. Mothers with an ANC booking visit had increased syphilis screening and time before delivery to allow for adequate treatment.
Untreated maternal syphilis has devastating consequences for the foetus. Congenital syphilis (CS) is preventable through timely maternal screening and treatment with robust surveillance. We evaluated CS surveillance data to identify gaps in CS surveillance and in the prevention cascade in South Africa.

Emergency departments (ED) provide care to populations with high rates of communicable diseases, like HIV, hepatitis C virus, and syphilis. For many patients, the ED is their sole entry point into the healthcare system and they do not routinely access screening and prevention services elsewhere. As such, the ED can serve an important public health role through communicable disease identification, treatment, and prevention. In this article, we examine national recommendations, peer-reviewed literature, and expert consensus to provide cutting edge strategies for implementing communicable infectious disease screening and prevention programs into routine ED care.

High incidences of congenital syphilis have been reported in areas along the Pacific coast of Colombia. In this retrospective study, conducted during 2018-2022 at a public hospital in Buenaventura, Colombia, we analyzed data from 3,378 pregnant women. The opportunity to prevent congenital syphilis was missed in 53.1% of mothers because of the lack of syphilis screening. Characteristics of higher maternal social vulnerability and late access to prenatal care decreased the probability of having >1 syphilis screening test, thereby increasing the probability of having newborns with congenital syphilis. In addition, the opportunity to prevent congenital syphilis was missed in 41.5% of patients with syphilis because of the lack of treatment, which also increased the probability of having newborns with congenital syphilis. We demonstrate the urgent need to improve screening and treatment capabilities for maternal syphilis, particularly among pregnant women who are more socially vulnerable.

OBJECTIVE: To evaluate the effect of preexposure prophylaxis (PrEP) initiation on bacterial sexually transmitted infection (STI) occurrence (overall; chlamydia; gonorrhea; syphilis), in MSM. DESIGN: Systematic review and meta-analysis. METHODS: Systematic searches were performed in PubMed, Embase, and Scopus without language restrictions until 1 February 2023. We sought studies reporting data for the estimation of incidence rate ratios (IRR), prevalence ratios or cumulative incidence ratios (the latter in equal time periods before and after PrEP initiation) regarding bacterial STI occurrence. Separate analyses were performed overall for any STI, syphilis, chlamydia and gonorrhea (overall; rectal; urethral; pharyngeal for the two latter conditions); ratios greater than unity denoted increase in STI occurrence after PrEP initiation. RESULTS: Twenty-three eligible studies with 11â776 participants (age range: 18-71âyears) with a median follow-up of 12âmonths were included. Overall, PrEP initiation was associated with a significant increase in the occurrence of any STI (pooled effect size: 1.15, 95% confidence interval (CI): 1.04-1.26), any gonorrhea (pooled effect size: 1.17, 95% CI: 1.02-1.34), any chlamydia (pooled effect size: 1.31, 95% CI: 1.09-1.58) and rectal chlamydia (pooled effect size: 1.31, 95% CI: 1.05-1.64), whereas a borderline increase was found in urethral chlamydia (pooled effect size: 1.25, 95% CI: 0.99-1.60, P â=â0.064). Changes in pharyngeal chlamydia and site-specific gonorrhea occurrence did not reach statistical significance. Syphilis showed virtually no change after PrEP initiation (pooled effect size: 0.99, 95% CI: 0.72-1.37). CONCLUSION: These results highlight the need for more comprehensive, accessible STI testing to tackle bacterial STI infections in PrEP users.

OBJECTIVES: Although oral pre-exposure prophylaxis (PrEP) for HIV is being rolled out in West Africa, data on sexually transmitted infections (STIs) in PrEP users are scarce. We assessed the prevalence, incidence and determinants of bacterial STIs in men who have sex with men (MSM) taking PrEP in Burkina Faso, Côte d'Ivoire, Mali and Togo. METHODS: A prospective cohort study among MSM initiating PrEP as part of a comprehensive HIV prevention package was conducted between 2017 and 2021 in community-based clinics in the four study countries. Molecular screening for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) was performed at months 0, 6 and 12. Serological testing for syphilis was performed every 3 months over the first year of follow-up. Determinants of CT and/or NG incidence were identified using Poisson generalised linear mixed models. RESULTS: A total of 598 participants with a median age of 24.7 years were included. Prevalence of CT and/or NG was 24.4% (95% CI 21.0 to 28.1), 22.4% (95% CI 18.4 to 26.8) and 29.0% (95% CI 24.2 to 34.1) at months 0, 6 and 12, respectively. The prevalence of syphilis ranged from 0.2% (95% CI 0.0 to 0.9) at month 0 to 0.8% (95% CI 0.2 to 2.4) at month 12. Ninety incident CT and/or NG infections occurred during a total follow-up time of 280.6 person-years (incidence rate 32.1 per 100 person-years, 95% CI 25.8 to 39.4). Three incident syphilis infections were detected during a total follow-up time of 459.7 person-years (incidence rate 0.7 per 100 person-years, 95% CI 0.1 to 1.9). CT and/or NG incidence was associated with condomless insertive anal sex (adjusted incidence rate ratio 1.96, 95% CI 1.04 to 3.71, p=0.038). CONCLUSIONS: CT and NG were frequent but syphilis was very infrequent in MSM using HIV PrEP in West Africa. HIV programme managers should integrate STI services into PrEP programmes.

INTRODUCTION: Doxycycline post-exposure prophylaxis (doxy-PEP) involves consuming 200 mg of doxycycline up to 72 hours after a condomless sex act to reduce the risk of bacterial sexually transmitted infections (STIs). Recent clinical trials of doxy-PEP have demonstrated significant reductions in syphilis, chlamydia and, to a lesser degree, gonorrhoea among gay, bisexual and other men who have sex with men (GBMSM). There is a high level of interest in doxy-PEP in the GBMSM community and, in response, the Australasian Society for HIV, Viral Hepatitis and Sexual Health Medicine (ASHM) held a national consensus conference with the aim of creating preliminary guidance for clinicians, community, researchers and policy makers. MAIN RECOMMENDATIONS: There was broad agreement that doxy-PEP should be considered primarily for the prevention of syphilis in GBMSM who are at risk of this STI, with a secondary benefit of reductions in other bacterial STIs. At the end of the consensus process, there remained some disagreement, as some stakeholders felt strongly that doxy-PEP should be considered only for the prevention of syphilis in GBMSM, and that the risk of increasing antimicrobial resistance outweighed any potential benefit from reductions in other bacterial STIs in the target population. The national roundtable made several other recommendations for clinicians, community, researchers and policy makers, as detailed in this article. ASHM will support the development of detailed clinical guidelines and education materials on doxy-PEP (www.ashm.org.au/doxy-pep). CHANGES IN MANAGEMENT AS A RESULT OF THIS CONSENSUS STATEMENT: For GBMSM at high risk of syphilis, and perhaps other bacterial STIs, clinicians may consider prescribing doxy-PEP for a limited period of time, followed by a review of ongoing need. Unlike human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP), doxy-PEP may not be suitable as a population-level intervention and should instead be used more selectively.

BACKGROUND: Syphilis and congenital syphilis rates have increased sharply in Colorado in the past 5 years. Congenital syphilis is passed during pregnancy in utero and can cause lifelong physical, developmental, and neurologic problems for the child, or can lead to miscarriage, stillbirth, or early infant death. Congenital syphilis is easily prevented if the mother receives timely testing, treatment, and prenatal care. Providers can play a key role in preventing congenital syphilis for women with social vulnerabilities, who have a higher likelihood of syphilis and/or congenital syphilis infection. METHODS: We surveyed 23 and interviewed 4 health care providers in southern Colorado in 2022 to record their experiences in providing sexual health care services. We asked providers with direct care experience about perceived barriers in effectively treating syphilis. RESULTS: The most significant barriers reported in the survey were the cost of treatment (26%) and the loss to follow-up (22%). Interviews revealed further challenges, including discretionary testing procedures, delays in screening results, treatment referral issues, and stigma around substance use and sexual activity. CONCLUSIONS: Elevated syphilis and congenital syphilis rates pose significant public health challenges. Coordinated interventions are necessary to effectively reduce the transmission of syphilis and congenital syphilis among women with upstream barriers. Potential care solutions include expanding rapid, point-of care testing and treatment options, supporting bicillin delivery or web-based inventory systems, offering anti-stigma training for providers, offering mental and behavioral health resources at providers' clinics, and expanding partnerships with syringe access programs.

Sexually transmitted infections (STIs) are commonly encountered in primary care. The Centers for Disease Control and Prevention and the US Preventive Services Task Force have both issued guidelines about screening for chlamydia, gonorrhea, syphilis, and HIV. By eliciting a sexual history, understanding their patients' anatomy, and considering factors which may increase the likelihood of STIs and their sequelae, clinicians can implement a practical, evidence-based approach to STI screening.

BACKGROUND: Infectious diseases including syphilis, HIV, and hepatitis B are major contributors to maternal and neonatal morbidity and mortality worldwide, especially in low- and middle-income countries (LMICs). The World Health Organization has prioritized elimination of vertical transmission of these three diseases. OBJECTIVES: To rapidly assess the impact of interventions designed to improve antenatal screening rates for syphilis, HIV, and hepatitis B in LMICs and to identify areas for future implementation research. SEARCH STRATEGY: A comprehensive search was conducted across PubMed, Embase, and EconLit, targeting articles published between January 1, 2013, and June 27, 2023. SELECTION CRITERIA: We included quantitative interventional studies in English, involving pregnant adults (15 years or older) from LMICs. Exclusions were studies based in high-income countries, qualitative studies, or those investigating accuracy of diagnostic methods. DATA COLLECTION AND ANALYSIS: From an initial 5549 potential studies, 27 were finalized for review after various screening stages. Data extraction covered aspects such as study design, intervention details, and outcomes. Findings were qualitatively synthesized within a systems thinking framework. MAIN RESULTS: The interventions assessed varied in terms of geographic locations, health care system levels, and modalities. The review highlighted the effectiveness of interventions such as community health interventions, service quality improvements, and financial incentives. CONCLUSIONS: The study underscores the potential of specific interventions in enhancing antenatal screening rates in LMICs. However, there is a discernible research gap concerning hepatitis B. The findings emphasize the importance of capacity building and health systems strengthening in public health interventions.
