Sexually transmitted infections (STIs) continue to increase in the United States with more than 2.5 million cases of gonorrhea, chlamydia, and syphilis reported to the Centers for Disease Control and Prevention in 2022. Untreated STIs in women can lead to adverse outcomes, including pelvic inflammatory disease, infertility, chronic pelvic pain, and pregnancy complications such as ectopic pregnancy, early pregnancy loss, stillbirth, and neonatal transmission. STI-related guidelines can be complex and are frequently updated, making it challenging to stay informed on current guidance. This article provides high-yield updates to support clinicians managing STIs by highlighting changes in screening, diagnosis, and treatment. One important topic includes new guidance on syphilis screening, including a clarified description of high community rates of syphilis based on Healthy People 2030 goals, defined as a case rate of primary or secondary syphilis > 4.6 per 100,000. Reproductive aged persons living in counties above this threshold should be offered syphilis screening. Additionally, American College of Obstetricians & Gynecologists now recommends syphilis screening three times during pregnancy regardless of risk—at the first prenatal visit, during the third trimester, and at delivery. In addition, new guidance to support consideration for extragenital screening for gonorrhea and chlamydia in women at sites such as the anus and pharynx is discussed. Other topics include the most recent chlamydia, gonorrhea, trichomoniasis, and pelvic inflammatory disease treatment recommendations; screening and treatment guidance for Mycoplasma genitalium; genital herpes screening indications and current diagnostic challenges; and the diagnosis and management of mpox in women and during pregnancy.

Syphilis and congenital syphilis (CS) cases have been rising in the U.S. and internationally since the 2000s. Social factors have been shown to increase the risk of CS transmission. The COVID-19 pandemic may have contributed to increased syphilis transmission. We aimed to quantify the rise in congenital syphilis (CS) rates at a large urban hospital and the impact of the COVID-19 pandemic on CS rates. We completed a retrospective chart review of 61 pregnant women with a positive test or previous diagnosis of syphilis at an urban academic hospital between 1 January 2016 and 1 June 2022. Maternal syphilis and CS rates increased over the 5 years (p < 0.001), particularly pre- and post-COVID-19 (p < 0.001). Of the mothers studied, 34.6% received adequate prenatal care, 62.7% received adequate screening, and 81.3% received adequate treatment. Stillbirth was noted in 6.6% of pregnancies. Of liveborn infants, 97.6% received appropriate treatment, and 45.1% received adequate follow-up. CS development was significantly associated with homelessness (p = 0.028) and past opioid use (p = 0.031). We concluded that maternal syphilis and CS rates have increased at our hospital, particularly during the COVID-19 pandemic. Access to prenatal care and timely maternal treatment are target areas for improvement. [ABSTRACT FROM AUTHOR]

Introduction: The incidence of sexually transmitted infections (STI) increased in the United States between 2017-2021. There is limited data describing STI co-testing practices and the prevalence of STI co-infections in emergency departments (ED). In this study, we aimed to describe the prevalence of co-testing and co-infection of HIV, hepatitis C virus (HCV), syphilis, gonorrhea, and chlamydia, in a large, academic ED. Methods: This was a single-center, retrospective cross-sectional study of ED patients tested for HIV, HCV, syphilis, gonorrhea or chlamydia between November 27, 2018-May 26, 2019. In 2018, the study institution implemented an ED-based infectious diseases screening program in which any patient being tested for gonorrhea/chlamydia was eligible for opt-out syphilis screening, and any patient 18-64 years who was having blood drawn for any clinical purpose was eligible for opt-out HIV andHCV screening. We analyzed data from all ED patients ≥13 years who had undergone STI testing. The outcomes of interest included prevalence of STI testing/co-testing and the prevalence of STI infection/co-infection. We describe data with simple descriptive statistics. Results: During the study period there were 30,767 ED encounters for patients ≥13 years (mean age: 43 ± 14 years, 52% female), and 7,866 (26%) were tested for at least one of HIV, HCV, syphilis, gonorrhea, or chlamydia. We observed the following testing frequencies (and prevalence of infection): HCV, 7,539 (5.0%); HIV, 7,359 (0.9%); gonorrhea, 574 (6.1%); chlamydia, 574 (9.8%); and syphilis, 420 (10.5%). Infectious etiologies with universal testing protocols (HIV and HCV) made up the majority of STI testing. In patients with syphilis, co-infection with chlamydia (21%, 9/44) and HIV (9%, 4/44) was high. In patients with gonorrhea, co-infection with chlamydia (23%, 8/35) and syphilis (9%, 3/35) was high, and in patients with chlamydia, co-infection with syphilis (16%, 9/56) and gonorrhea (14%, 8/56) was high. Patients with HCV had low co-infection proportions (<2%). Conclusion: Prevalence of STI co-testing was low among patients with clinical suspicion for STIs; however, co-infection prevalence was high in several co-infection pairings. Future efforts are needed to improve STI co-testing rates among high-risk individuals. [ABSTRACT FROM AUTHOR]

Background: The primary risk of HIV transmission in China has shifted from injecting drug use (IDU) to sexual contact since 2006. We evaluated the prevalence trends of HIV, hepatitis C virus (HCV), syphilis, and sexual and drug use behaviors among drug users. Methods: People who use drugs participated in any of four rounds of cross-sectional surveys during 2010–2017 in Chongqing. Participants were tested for HIV, HCV, and syphilis. Questionnaire interviewing was conducted to collect behavioral information. Chi-square and trend tests were employed to assess the changes in diseases and behaviors over time. Results: A total of 8,171 people who inject drugs (PWID) and 5,495 non-injection drug users (NIDU) were included in the analyses. HIV prevalence among PWID in four rounds of the survey in 2010–11, 2012–13, 2014–15, and 2016–17 was 11.5%, 9.7%, 6.5%, and 6.9%, and among NIDU, 2.4%, 1.4%, 2.1% and 2.6%, respectively. HCV prevalence among PWID was 83.5%, 85.2%, 67.1% and 79.7% (P < 0.001), and among NIDU, 22.2%, 10.8%, 13.4% and 14.8%, (P < 0.001). Conclusions: The declining HIV and HCV prevalence among PWID is coincident with declining risky drug use behaviors. Tailored disease prevention and interventions targeting PWID and NIDU are needed.

Female sex workers (FSWs) are considered a high-risk group for sexually transmitted infections (STIs). However, limited data exist on the prevalence and trends of HIV, syphilis and HCV among FSWs in the Sino-Vietnam border area. To determine the prevalence, trends and correlates of STIs among Chinese local FSWs (CL-FSWs) and cross-border migrant FSWs (CM-FSWs), we conducted consecutive cross-sectional surveys from 2016 to 2021, recruiting 7747 CL-FSWs and 932 CM-FSWs. The overall HIV, syphilis and HCV prevalence declined from 1.0%, 8.8% and 1.7% to 0.1%, 0.9% and 0.3%, respectively. There was no significant downward trend in the overall HIV and syphilis prevalence. However, HCV prevalence showed a decreasing trend among CL-FSWs. CM-FSWs had higher HIV prevalence (2.5% vs. 0.6%). Similarities and differences in STIs-related factors existed between CM-FSWs and CL-FSWs. For instance, receiving HIV-related services in the last year reduced the risk of HIV infection (for CM-FSWs: aOR = 0.234, 95% CI: 0.055–0.993; for CL-FSWs: aOR = 0.182, 95% CI: 0.058–0.567). Serving male clients at least 50 years old increased the risk of syphilis infection (for CM-FSWs: aOR = 4.277, 95% CI: 1.535–11.917; for CL-FSWs: aOR = 1.404, 95% CI: 1.087–1.815). Moreover, CM-FSWs with past-year STIs history had a higher risk of HIV (aOR = 34.976, 95% CI: 5.338–229.176) and HCV infection (aOR = 17.649, 95% CI: 1.846–168.846), both of which were associated with multiple factors in CL-FSWs. It is therefore necessary to develop effective, accessible, high-quality and targeted interventions for CM-FSWs and CL-FSWs. [ABSTRACT FROM AUTHOR]

Background: Worldwide, there was an estimated 7.1 million new cases of syphilis in 2020, and most of the infections were found in developing countries like Nigeria. The objective of the study was to determine the prevalence and risk factors for syphilis among human immunodeficiency virus (HIV)‑infected patients in Lagos. Methods: A cross‑sectional study was conducted in an HIV Clinic in Lagos, Nigeria, from April to June 2017 and 385 HIV‑infected adult participants 18 years and above were recruited into the study. Structured questionnaires were used to collect data on sociodemographic and risk factors for syphilis. Blood samples were collected from all participants and tested for syphilis using rapid plasma reagin and Treponema pallidum hemagglutination assay test kits. Data were analyzed using SPSS (IBM) V. 20. Bivariate analysis was carried out using Chi‑square, Fisher’s exact test, and Student’s t‑test on sociodemographic and risk behavioral factors. Multivariable logistic regression analysis was performed with variables that were significantly associated with syphilis in bivariate analysis. A P < 0.05 was considered to be statistically significant. Results: Out of 388 HIV‑infected patients recruited into the study, 262 (67.5%) were female. The mean age was 43.6 ± 10.1 years, and 137 (35.3%) of them were in the age group of 41–50 years. The prevalence of syphilis in HIV‑infected patients was 1.8%. The prevalence of syphilis was significantly higher in males (4.8%) than females (0.4%). The prevalence of syphilis was higher in those with no education or primary school education, and multiple sexual partners were statistically significant in the bivariate analysis but not in the multivariate analysis. Male gender was the only independent risk factor for syphilis, with an odds ratio of 11.79 (95% confidence interval [1.26–106.5], P = 0.03) in multivariate analysis. Conclusion: The prevalence of syphilis in this study was lower than previous work done in other HIV‑positive cohorts in Nigeria. Males were more affected significantly in this study. Routine screening and testing for syphilis should be integrated into HIV care, especially in males. [ABSTRACT FROM AUTHOR]

Objectives: Our objective was to obtain long‐term data on the incidence of sexually transmitted infections (STIs) and their association with behavioural factors after widespread pre‐exposure prophylaxis (PrEP) implementation. Methods: This was a time‐to‐event analysis of a national PrEP cohort in Switzerland (SwissPrEPared study). Participants were people without HIV interested in taking PrEP with at least two STI screening visits. Primary outcomes were incidence rate of gonorrhoea, chlamydia, and syphilis. The association between behavioural factors and STI diagnosis was expressed using hazard ratios. We adjusted for testing frequency and calendar year. Results: This analysis included 3907 participants enrolled between April 2019 and April 2022, yielding 3815.7 person‐years of follow‐up for gonorrhoea (15 134 screenings), 3802.5 for chlamydia (15 141 screenings), and 3858.6 for syphilis (15 001 screenings). The median age was 39 years (interquartile range [IQR] 32–47), 93.8% (n = 3664) identified as men who have sex with men (MSM). The incidence was 22.8 (95% confidence interval [CI] 21.3–24.4) per 100 person‐years for gonorrhoea, 26.3 (95% CI 24.7–28.0) for chlamydia, and 4.4 (95% CI 3.8–5.1) for syphilis. Yearly incidence rates decreased between 2019 (all bacterial STIs: 81.6; 95% CI 59.1–109.9) and 2022 (all bacterial STIs: 49.8; 95% CI 44.6–55.3). Participants reporting chemsex substance use were at higher risk of incident STIs, as were those reporting multiple sexual partners. Younger age was associated with a higher risk of gonorrhoea and chlamydia. Conclusions: Incidence rates of bacterial STIs decreased over time. Young MSM, those with multiple partners, and those using chemsex substances were at increased risk of STIs. [ABSTRACT FROM AUTHOR]

Syphilis is a primarily sexually transmitted chronic infection caused by the spirochete, Treponema pallidum. There has been a dramatic increase in cases of syphilis in the Western world, with cases tripling in England between 2010 and 2019. Syphilis can present in a dental setting and dentists should enquire about sexual history if suspicious of syphilis to ensure early diagnosis and treatment. We present five cases seen with variable presentations of oral syphilis between 2016 and 2021 in a dental hospital. [ABSTRACT FROM AUTHOR]

Aim: The aim of this study is to evaluate the demographic and clinical features of syphilis patients followed up in a tertiary referral hospital, and thus to provide current contributions to epidemiological data related to syphilis. Material and Methods: The demographic characteristics, clinical and laboratory findings, and treatments received of all patients diagnosed with syphilis and followed up in our clinic between January 2019 and June 2023 were evaluated retrospectively. Results: We included a total of 118 patients, 24 women and 94 men. The average age of the patients was 36.56±5.1 years. Fortyone of the patients (34.7%) were married, 56 were single (47.4%) and the marital status of 21 (17.8%) was unknown. Sixty-two of the patients (52.5%) had primary syphilis, 29 (24.6%) had secondary syphilis and 27 (22.9%) had latent syphilis. When the patients' admission symptoms were evaluated, genital chancre was found in 58 (49.1%), roseola syphilitica in 24 (20.3%), mucous plaque in 11 (9.3%), condyloma lata in 7 (5.9%) and syphilis papulosa psoriasiformis in 3 (2.5%) patients. Twenty-five patients (21.1%) were asymptomatic. Transmission from spouse was in 14 (11.9%) patients while suspicious sexual contact was in 77 (65.3%) patients. The source of transmission was unknown in 27 (22.9%) patients. Response to treatment was obtained in all of the patients who were not lost to follow up. Twenty-two of the patients (18.64%) were HIV positive. Conclusion: Rising syphilis incidence which is observed globally in the recent years indicates the need to raise the level of public awareness about the disease and its transmission routes. In addition, since it can mimic many diseases, it should always be considered in the differential diagnosis, especially in patients with a history of suspicious sexual contact. It is necessary to investigate other sexually transmitted diseases, especially HIV, in patients diagnosed with syphilis. [ABSTRACT FROM AUTHOR]

Syphilis remains a global public health problem, with growing incidence in most regions of the world, particularly among women of childbearing age. This alarming trend has led to an increase in cases of congenital syphilis, resulting in devastating consequences. While the implementation of measures by the World Health Organization (WHO) and various governments has contributed to a decline in the global incidence of congenital syphilis, many countries are facing an escalating crisis, as incidence continues to rise. This mini-review aims to provide an overview of the current state of this disease in different parts of the world, focusing on the most affected populations and highlighting congenital syphilis as a marker of vulnerability. It also focuses on Switzerland, a country with a robust economy, to identify shortcomings in the healthcare system that contribute to the persistence of congenital syphilis, even though the infection is easily detectable and treatable. In conclusion, this mini-review highlights the persistent risk of congenital syphilis worldwide, regardless of country prevalence or economic status, and underscores the need for sustained efforts to reach underserved women, emphasizing the vital role of comprehensive training for healthcare professionals.

The incidence of syphilis has been increasing in the USA since 2000. Notably, the coronavirus disease 2019 pandemic negatively impacted the public health efforts to contain the spread of sexually transmitted diseases including syphilis and congenital syphilis. Clinical manifestations of syphilis are predominantly mucocutaneous lesions, thus dermatologists are primed to recognize the myriad presentations of this disease. Primary syphilis is classically characterized by a painless transient chancre most often located in the genital area. Secondary syphilis typically manifests clinically as systemic symptoms in addition to a mucocutaneous eruption of which a variety of forms exist. Although less common in the era of effective penicillin treatment, late clinical manifestations of syphilis are described as well. In addition to recognition of syphilis on physical examination, several diagnostic tools may be used to confirm infection. Treponema pallidum spirochetes may be detected directly using histopathologic staining, darkfield microscopy, direct fluorescent antibody, and polymerase chain reaction assays. A table detailing the histopathologic features of syphilis is included in this article. Serologic testing, non-treponemal and treponemal tests, is the preferred method for screening and diagnosing syphilis infections. Two serologic testing algorithms exist to aid clinicians in diagnosing positive syphilis infection. Determining the correct stage of syphilis infection combines results of serologic tests, patient history, and physical examination findings. Using the current Centers for Disease Control and Prevention case definitions and treatment guidelines, a management algorithm is proposed here. Penicillin remains the pharmacological treatment of choice although specific clinical situations allow for alternative therapies. Syphilis is a reportable disease in every state and should be reported by stage according to individual state requirements. Screening recommendations are largely based upon risks encountered through sexual exposures. Likewise, sexual partner management includes evaluating and treating persons exposed to someone diagnosed with an infective stage of syphilis. Close clinical follow-up and repeat testing are recommended to ensure appropriate response to treatment. This guide will discuss the current epidemiology of syphilis and focus on practice aspects of diagnosis and management, including public health reporting. [ABSTRACT FROM AUTHOR]

Syphilis infection disproportionately impacts Black sexual and gender minorities (SGM) in the United States. The extent of this impact among those living with HIV has been minimally examined. This study sought to examine lifetime syphilis prevalence and associated factors in a community sample of predominantly Black SGM living with HIV in the Southeastern US. Participants (N = 174) enrolled in a stigma-mitigation trial for people living with HIV in Atlanta, Georgia, completed a sub-study involving testing for Treponema pallidum antibodies, indicative of lifetime syphilis infection. We performed chi-square and Fisher's exact tests to assess sociodemographic and healthcare differences by presence/absence of lifetime syphilis infection. Most participants identified as non-Hispanic Black (n = 142/174; 81.6%) and cisgender male (n = 146/174; 83.9%). More than two thirds (n = 120/174) identified as gay/homosexual. We documented a 55.7% (n = 97/174) lifetime prevalence of syphilis infection and observed differences by sexual identity, with 77.3% (n = 75/97) of those screening positive reporting gay/homosexual identity relative to 58.4% (n = 45/77) of those screening negative (chi-square[1] = 7.8, p < 0.010). Findings underscore how syphilis prevention efforts have missed the most marginalized, warranting a renewed, comprehensive strategy for improving the sexual health of Black SGM. Embedding targeted, respectful community engagement, expanded testing access, and healthcare provider training into broader sexual health and psychosocial wellness efforts is needed.

Background: The yearly incidence of syphilis has risen markedly in Japan and worldwide. There has also been an increased incidence of human papilloma virus associated oropharyngeal cancer, which presents with clinical features similar to those of syphilis. Objective: A case of syphilis with clinical manifestation resembling that of human papilloma virus associated oropharyngeal cancer is reported, along with a literature review of similar cases. Methods: Clinical case reports and review of previous literature. Conclusion: Syphilis may cause irregular mucosal lesions of the oropharynx and cystic lymphadenopathy. It is difficult to diagnose syphilis only by examining pathological specimens, without clinical information such as Treponema pallidum antibody findings. It is necessary to correctly understand the characteristics of syphilis and human papilloma virus associated oropharyngeal cancer to ensure prompt diagnosis and treatment. [ABSTRACT FROM AUTHOR]

The resurgence of syphilis and subsequent risk for newborns has been described worldwide; however, European data on this congenital infection is lacking. We report the activity of a multidisciplinary specialized unit assisting a large area in the Southern Italy. A retrospective cohort study has been conducted at the Perinatal and Pediatric Infectious Diseases Units of the Federico II University of Naples, enrolling all newborns and children referred from January 2010 to June 2022 exposed to Treponema pallidum in utero and/or congenitally infected. A total of 323 patients were included in the analysis. Twenty (6.2%) received a diagnosis of confirmed congenital syphilis (CS) and one died. Fifteen CS cases had typical clinical features. Since 2017, the number of referred neonates tripled while the rate of late maternal diagnoses did not significantly differ. When compared with mothers of exposed infants, mothers of CS cases were younger (25 ± 7.2 vs 29.9 ± 6 years, p = 0.041), had less previous pregnancies (0.64 vs 1.11, p = 0.044), and received a diagnosis of syphilis at a later stage of pregnancy (86% vs 20%, from third trimester or later on; p < 0.001). Appropriate maternal therapy was protective against vertical transmission (− 1.2; − 1.4, − 1 95% CI; p < 0.001). Paternal syphilis status was known in 36% of cases. Conclusion: CS has still a significant impact. Prevention should be implemented towards specific maternal risk profiles. A specialized unit is the preferable model to improve surveillance and healthcare for this neglected population. What is Known: • The resurgence of syphilis and subsequent risk for newborns has been described worldwide. • European data on this congenital infection is lacking. What is New: • Congenital syphilis has a significant impact still in Europe and prevention should be implemented towards specific maternal risk profiles. • A specialized unit is the preferable model to improve surveillance and healthcare for this neglected population.

Objectives: Syphilis has been called the great mimicker or the great imitator due to its myriad of clinical presentations. Despite strenuous concerted efforts toward the elimination of syphilis, it still remains a goal to be achieved. During recent years, many different trends of syphilis have been reported from around the globe. Methods: A retrospective observational clinico-investigative study was carried out to analyze the 10-year trends of syphilis at one of the largest public sector hospitals in India. Results and Conclusion: Both venereal disease research laboratory and Treponema pallidum Hemagglutination assay positivity rates showed a significant declining trend from 2007 to 2016, reflecting the success of the National Sexually Transmitted Infection Prevention and Control Program.

Background: Syphilis is a treatable bacterial infection caused by Treponema pallidum. There has been a change in incidence of syphilis in various nations over the years. Aim: To study the epidemiological trends, demographic profile, high-risk behaviour, clinical pattern, and stage of syphilis over the last ten years in patients presenting to an STD clinic in a tertiary care hospital. Material and Methods: This was a retrospective observational study over ten years. Records of all confirmed syphilis cases were analysed in relation to demography and clinical profile. Results: There were a total of 3,110 STD patients among whom 31 cases (accounting for 0.99%) of confirmed syphilis were seen. There was a significant increase in cases in the last five years of study, especially in the last year. An increase in primary (PS) and secondary syphilis (SS) was observed. Males outnumbered females (3:1). Mean age of patients was 35.0 ± 11.53 years. Professionals were most common (22.6%) having syphilis followed by farmers (19.35%). A significant proportion (45.1%) of our patients were at least graduates. Unprotected sex was seen in all the patients followed by extramarital/premarital sex (71.35%). There were 16.12% of cases who had a history of paid sex and 9.7% were homosexuals. SS and latent syphilis were more common (38.7% each) than PS (19.35%). In PS single chancre and in SS truncal asymptomatic rash was the commonest clinical presentation. Limitation: Single-centre study, including only self-reported patients leading to a small sample size, is the major limitation of the study. Conclusion: The increased trend of primary and secondary syphilis in recent years highlights that there is a risk of an impending epidemic. [ABSTRACT FROM AUTHOR]

Background: There is a change in the pattern and prevalence of acquired syphilis due to better awareness, surveillance, laboratory diagnosis, and treatment in India in recent years. However, restrictive measures for COVID-19 may produce different effects on incidence. Aims and Objectives: We aimed to study the changing trend of acquired syphilis in relation to COVID-19 outbreak in a tertiary care hospital in North India. Materials and Methods: A retrospective analysis of all the cases of sexually transmitted infections (STIs) was done from January 2016 to June 2022. Demographic, clinical, and laboratory data of acquired syphilis were recorded and analyzed for changing trends in prevalence, clinical presentations, association with HIV and other sexually transmitted diseases (STDs), and its relation to COVID-19. Statistical analysis was done using SPSS software. Results: A total of 1105 patients attended STD clinic from January 2016 to June 2022, of which 216 patients were venereal disease research laboratory and Treponema pallidum hemagglutination assay positive (19.5%). Before COVID-19, there was an increasing trend of acquired syphilis (late latent). Patients diagnosed with syphilis pre- and postlockdown did not differ significantly in their mean age, median age, male/female ratio, and HIV status. However, there is an increase in number of cases of primary and secondary syphilis postlockdown which was statistically significant. Conclusion: Restrictive measures for COVID-19 during the lockdown produced a declining trend of syphilis. It is unclear whether the observed decrease in number of STI cases was due to true decline, inadequate testing, underreporting, or avoidance of high-risk sexual activities. The upsurge in the number of cases of acquired syphilis after lockdown suggests the possibility that lockdowns did not completely disrupt STI transmission. [ABSTRACT FROM AUTHOR]

Background We describe trends in prevalence and identify factors associated with Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), syphilis, and Trichomonas vaginalis (TV) diagnosed in pregnancy among US people with human immunodeficiency virus (PWH) and evaluate associations of sexually transmitted infections (STIs) with preterm birth (PTB). Methods We included pregnant PWH enrolled in the Surveillance Monitoring for ART Toxicities dynamic cohort of the Pediatric HIV/AIDS Cohort Study network who delivered between 2010 and 2019. Multivariable log-binomial or Poisson generalized estimating equation models were used to estimate the association of calendar year with each STI, controlling for confounders; the association of demographic and clinical factors with each STI; and the association of each STI with PTB. Results The sample included 2241 pregnancies among 1821 PWH. Median age at delivery was 29.2 years; 71% of participants identified as Black or African American. STI prevalence was: CT 7.7%, NG 2.3%, syphilis 2.4%, and TV 14.5%; 30% had unknown TV status. There were no temporal changes in STI prevalence. Younger age and initial HIV viral load ≥400 copies/mL were associated with increased risk of CT, NG, and TV. Recreational substance use was a risk factor for NG, syphilis, and TV. No STI was associated with PTB. Conclusions Unlike nationwide trends, no changes in STI prevalence during the study period were observed. The large proportion with unknown TV status underscores the need for increased adherence to screening guidelines. STIs diagnosed during pregnancy in PWH were not associated with risk of PTB.

Aim: Sexually transmitted infections remain a neglected area of research in geriatrics. However, in the global aging societies, sexual health among the middle‐aged and older adults is an emerging public concern. High‐income countries are facing a resurgence of syphilis cases among young generations, but little is known about its prevalence in older populations. We aimed to investigate the national trend of syphilis cases in Japan. Methods: This nationwide observational study used the publicly‐available database (2009–2019) to calculate crude and age‐adjusted incidence rates of syphilis per 100 000 population by age, sex and clinical stage. We collected data from patients aged ≥50 years and performed joinpoint regression analysis to estimate long‐term trends and average annual percentage changes (AAPCs). Results: The total number of patients with syphilis increased about 8‐fold from 165 in 2009 to 1280 in 2019. AAPCs of crude incidence rates significantly increased in every age category; 33.2% in 50–59 years, 23.8% in 60–69 years and 20.9% in ≥70 years. Age‐adjusted incidence rates have surged at AAPCs of 28.7% in men and 23.1% in women, reaching 4.09 in men and 0.71 in women in 2019. By clinical stage, marked increases were observed in primary (AAPCs, 42.3% in men and 41.6% in women) and secondary syphilis (AAPCs, 24.9% in men and 24.2% in women). Conclusions: An up‐toward trend of syphilis among people aged ≥50 years was observed. The importance of sexual health among older people should be highlighted in this aging Japanese society.

Coronavirus (COVID-19) laid bare the disproportionate effects of infectious agents on vulnerable communities. However, historically, infectious diseases have long been known to affect certain communities to a greater extent than others. The mechanisms behind these differences are multifactorial, and lie less in biological susceptibility and instead more on socioeconomic factors and other social determinants of health. This article highlights health disparities in common infections such as respiratory syncytial virus, tuberculosis, HIV, syphilis, and influenza and will use lessons learned from previous pathogens and infectious disease disparities in vulnerable populations to provide context to the COVID-19 pandemic.

The rate of syphilis infections among sexual minority men (SMM) has continued to increase in recent decades. As such, this analysis sought to identify demographic, biological, and behavioral factors associated with recent syphilis infection in emerging adult SMM. Data were drawn from a 3-year cohort study of emerging adult SMM (n = 665), from July 2014 to March 2019. Biannual study assessments included rapid HIV testing and behavioral surveys. At baseline, and at the 18- and 36-month time points, participants underwent chlamydia, gonorrhea, and syphilis screening. Generalized estimating equations were used to generate four models of repeated syphilis screening. In this racially/ethnically and socioeconomically diverse sample of SMM, 5.0% of participants tested positive for syphilis at baseline and 9.0% had an infection at the subsequent time points. Across all models, racial/ethnic minority SMM had higher odds of syphilis. Higher odds of syphilis infection were also significantly associated with more frequent condomless anal sex, more frequent marijuana use, HIV seropositivity, not currently using pre-exposure prophylaxis (PrEP), and not receiving syphilis testing in the previous 6 months; lower odds were associated with more frequent oral sex and more frequent alcohol use. These findings support current screening guidelines based on SMM who may be at increased risk for sexually transmitted infection (STI) acquisition, such as people living with HIV or those who engage in condomless sex. Further, our findings of reduced syphilis incidence among those who are on PrEP and engaged in regular STI testing support existing efforts to increase the availability and accessibility of preventive sexual health care for SMM.

Background: The awareness and willingness to use doxycycline-based syphilis chemoprophylaxis among men who have sex with men (MSM) in China remain largely unknown.Methods: We recruited MSM online from Nanjing, Wuhan and Changsha between August and October of 2021, collected data from online survey, analyzed their data using descriptive statistics, and constructed binary logistic regression for factors associated with awareness and willingness to use chemoprophylaxis for syphilis and HIV.Results: Of 725 participants (44.0% of which resided in Nanjing, 37.7% in Changsha, and 18.3% in Wuhan), a majority were under 25 years of age; 62.2% had college degrees; 11.3% were HIV positive; and 5.10% had prior syphilis infection. Only 28.83% of participants had heard of syphilis chemoprophylaxis before. Odds of knowing syphilis chemoprophylaxis were higher in those who think it is necessary to have syphilis chemoprophylaxis versus those who think it is unnecessary (P = 0.002), and were higher in those whose acquaintance had chemoprophylaxis experience before (P < 0.001). Meanwhile, those who had no previous doxycycline using history, or had positive attitude were more likely to be willing to accept syphilis chemoprophylaxis (P = 0.009, P < 0.001). Over two-thirds (67.8%) of participants preferred the PEP mode in syphilis chemoprophylaxis, and side-effects of drugs remains their most worrying aspect.Conclusions: We observed elevated interest in syphilis chemoprophylaxis in MSM in our investigational areas, indicating that the combination of HIV and syphilis chemoprophylaxis in China is promising.

Background: Birth asphyxia is one of the leading causes of neonatal mortality worldwide. In Uganda, it accounts for 28.9% of all neonatal deaths. With a view to inform policy and practice interventions to reduce adverse neonatal outcomes, we aimed to determine the prevalence and factors associated with birth asphyxia at two referral hospitals in Northern Uganda.Methods: This was a cross-sectional study, involving women who gave birth at two referral hospitals. Women in labour were consecutively enrolled by the research assistants, who also attended the births and determined Apgar scores. Data on socio-demographic characteristics, pregnancy history and care during labour, were obtained using a structured questionnaire. Participants were tested for; i) malaria (peripheral and placental blood samples), ii) syphilis, iii) white blood cell counts (WBC), and iv) haemoglobin levels. The prevalence of birth asphyxia was determined as the number of newborns with Apgar scores < 7 at 5 min out of the total population of study participants. Factors independently associated with birth asphyxia were determined using multivariable logistic regression analysis and a p-value < 0.05 was considered statistically significant.Results: A total of 2,930 mother-newborn pairs were included, and the prevalence of birth asphyxia was 154 [5.3% (95% confidence interval: 4.5- 6.1)]. Factors associated with birth asphyxia were; maternal age ≤ 19 years [adjusted odds ratio (aOR) 1.92 (1.27-2.91)], syphilis infection [aOR 2.45(1.08-5.57)], and a high white blood cell count [aOR 2.26 (1.26-4.06)], while employment [aOR 0.43 (0.22-0.83)] was protective. Additionally, referral [aOR1.75 (1.10-2.79)], induction/augmentation of labour [aOR 2.70 (1.62-4.50)], prolonged labour [aOR 1.88 (1.25-2.83)], obstructed labour [aOR 3.40 (1.70-6.83)], malpresentation/ malposition [aOR 3.00 (1.44-6.27)] and assisted vaginal delivery [aOR 5.54 (2.30-13.30)] were associated with birth asphyxia. Male newborns [aOR 1.92 (1.28-2.88)] and those with a low birth weight [aOR 2.20 (1.07-4.50)], were also more likely to develop birth asphyxia.Conclusion: The prevalence of birth asphyxia was 5.3%. In addition to the known intrapartum complications, teenage motherhood, syphilis and a raised white blood cell count were associated with birth asphyxia. This indicates that for sustained reduction of birth asphyxia, appropriate management of maternal infections and improved intrapartum quality of care are essential. [ABSTRACT FROM AUTHOR]- Published

We assessed HIV and syphilis infection among MSM and TGW attending Silom Community Clinic from 2017 to 2019. Walk-in and referral clients completed a registration application including a question on gender identity. We compared the prevalence of HIV, syphilis, and HIV and syphilis coinfection among TGW and MSM. In a total of 1050 clients, 276 (26.3%) were TGW and 774 (74.7%) were MSM. Among TGW clients, HIV prevalence was 29.8%, syphilis prevalence was 38.4%, and coinfection prevalence was 18.5%. Comparing prevalence among TGW to MSM, the adjusted prevalence ratio (aPR) for HIV was 1.8 (95% CI:1.4–2.3), for syphilis was 1.2 (95% CI:1.0–1.4), and for HIV and syphilis coinfection was 2.1 (95% CI:1.4–2.9). The prevalence of syphilis was higher than HIV among TGW, with a PR of 1.3 (95% CI:1.1–1.6), and among MSM, with a PR of 1.4 (95% CI:1.2–1.7). TGW age 15–21 years had an HIV prevalence of 16.9% and syphilis prevalence of 30.8%. After adjusting for age, referral, and sexual behaviors, TGW remain significantly associated with HIV and syphilis prevalence. There is a substantial burden of HIV and HIV/syphilis co-infection among TGW. HIV/STI prevention are needed for TGW, including linkage to HIV care. [ABSTRACT FROM AUTHOR]

Objectives. To determine the prevalence of antibodies against Treponema pallidum and herpes simplex virus type 2 (HSV-2), and to identify the factors associated with these infections among migrants in transit in Chiapas, Mexico. Methods. Cross-sectional study conducted during 2021-2022, in three migrant shelters in Chiapas, Mexico. Participants answered a questionnaire and provided a blood sample to detect antibodies against Treponema pallidum and HSV-2. The study calculated seroprevalence and assessed associated factors using Chi-square (χ²) tests and odds ratios. Results. A total of 462 migrants participated, with an average age of 31.2 years; 56.9% were women, and 41.1% came from Honduras. The seroprevalence of HSV-2 was 29.9%; for syphilis it was 4.5%, and it was higher in men (8.0%) than in women (1.9%). Among pregnant women, 15.4% had antibodies against syphilis. Notable variables associated with syphilis include being male, having a history of genital lesions, having same-sex partners, and seropositivity to HSV-2. Regarding HSV-2, factors associated with infection included being female, age, schooling, sleeping in the street, a history of HIV testing, early sexual debut, number of sexual partners, and syphilis. Conclusions. A high prevalence of syphilis and HSV-2 was found among the migrant population evaluated. Syphilis is confirmed as a re-emerging infection, even in women. Migrants have vulnerabilities associated with sexual behavior, so prevention, diagnosis, and treatment measures should be focused on this population group. [ABSTRACT FROM AUTHOR]

Objective: To report the clinicopathologic features of acquired oral syphilis cases in South American countries. Materials and Methods: Clinical data were retrospectively collected from the records of 18 oral diagnostic services in Argentina, Brazil, Chile, Colombia, Venezuela, Uruguay, and Peru. Serologies of nontreponemal and treponemal tests were used for diagnosis. Results: The series comprised 339 cases of acquired oral syphilis. Secondary syphilis ranked as the most common stage (86.7%). Lesions were more frequent among males (58.0%) and young adults with a mean age of 33.3 years. Individuals aged 20–29 years were most affected (35.3%). The most commonly involved sites were the tongue (31.6%), lip/labial commissure (25.1%), and hard/soft palate (20.4%). Clinically, acquired oral syphilis usually presented as mucous patches (28.4%), papules (25.7%), and ulcers (18.1%). Skin manifestations occurred in 67.7% of individuals, while lymphadenopathy and fever were observed in 61.3% and 11.6% of all subjects, respectively. Most patients were treated with the benzathine penicillin G antibiotic. Conclusion: This report validates the spread of acquired oral syphilis infection among young adults in South America. Our directives include accessible diagnostic tools for proper disease screening, surveillance, and counselling of affected individuals, especially in low‐ and middle‐income countries.

Background: Although data from large implementation trials suggest that sexually transmissible infection (STI) risk increases among gay and bisexual men who initiate HIV pre-exposure prophylaxis (PrEP), there are few data on the trends in population-level STI incidence in the years following widespread PrEP implementation. We aimed to describe trends in bacterial STI incidence among gay and bisexual men using PrEP across Australia in the context of broad PrEP availability through Australia's subsidised medicines scheme.Methods: We analysed linked clinical data from HIV-negative gay and bisexual men aged 16 years or older who had been prescribed PrEP across a sentinel surveillance clinical network, including 37 clinics in Australia, between Jan 1, 2016, and Dec 31, 2019. Patients were included if they had STI testing at least twice during the observation period. Repeat testing methods were used to calculate chlamydia, gonorrhoea, syphilis, and any STI incidence rates during individuals' periods of PrEP use. Incidence rate ratios (IRRs) for estimated change in incidence per half calendar year (6-month) period were calculated using negative binomial regression. Secondary analyses compared STI incidence rates across individuals initiating PrEP in each year from 2016 to 2019, as well as by length of time using PrEP (per each additional 6 months of PrEP use).Findings: 22 730 men were included in the analyses. During the observation period, 11 351 chlamydia infections were diagnosed in 6630 (30·1%) of 22 034 men over 25 991·2 person-years of PrEP use (incidence rate 43·7 cases [95% CI 42·9-44·5] per 100 person-years). Chlamydia incidence decreased from 48·7 cases per 100 person-years in July-December, 2016, to 42·0 cases per 100 person-years in July-December, 2019 (IRR for estimated change per 6-month period 0·98 [95% CI 0·97-0·99]; p=0·0031). 9391 gonorrhoea infections were diagnosed in 5885 (26·9%) of 21 845 men over 24 858·7 person-years of PrEP use (incidence rate 37·8 cases [95% CI 37·0-38·5] per 100 person-years). Gonorrhoea incidence decreased from 45·5 cases per 100 person-years in July-December, 2016, to 37·2 cases per 100 person-years in July-December, 2019 (IRR 0·97 [95% CI 0·96-0·98]; p<0·0001). Declines in chlamydia and gonorrhoea incidence were most prominent in the first 18 months of observation and incidence was stable thereafter. 2062 syphilis infections were diagnosed in 1488 (7·7%) of 19 262 men over 21 978·9 person-years of PrEP use (incidence rate 9·4 cases [95% CI 9·0-9·8] per 100 person-years). Syphilis incidence increased from 6·2 cases per 100 person-years in July-December, 2016, to 9·8 cases per 100 person-years in July-December, 2019 (IRR 1·08 [95% CI 1·05-1·10]; p<0·0001).Interpretation: Chlamydia and gonorrhoea incidence among gay and bisexual men using PrEP were highest in the early months of PrEP implementation in Australia and stabilised at slightly lower rates thereafter following wider PrEP uptake. Lower prospective STI risk among people initiating PrEP in later years contributed to the observed trends in STI incidence. Widespread PrEP implementation can contribute to increased STI screening and detection.Funding: Australian Department of Health, National Health and Medical Research Council.

Background Despite rising rates of syphilis among people with human immunodeficiency virus (HIV; PWH) in the United States, there is no optimal syphilis screening frequency or prioritization. Methods We reviewed records of all PWH in care between 1 January 2014 and 16 November 2018 from 4 sites in the Centers for AIDS Research Network of Integrated Clinical Systems Cohort (CNICS; N = 8455). We calculated rates of syphilis testing and incident syphilis and used Cox proportional hazards models modified for recurrent events to examine demographic and clinical predictors of testing and diagnosis. Results Participants contributed 29 568 person-years of follow-up. The rate of syphilis testing was 118 tests per 100 person-years (95% confidence interval [CI]: 117–119). The rate of incident syphilis was 4.7 cases per 100 person-years (95% CI: 4.5–5.0). Syphilis diagnosis rates were highest among younger cisgender men who have sex with men and transgender women, Hispanic individuals, people who inject drugs, and those with detectable HIV RNA, rectal infections, and hepatitis C. Conclusions We identified PWH who may benefit from more frequent syphilis testing and interventions for syphilis prevention. [ABSTRACT FROM AUTHOR]

Background: This study aimed to examine variations in the incidence rates of sexually transmitted infections (STIs; i.e., chlamydia, gonorrhea, and syphilis) across the urban-rural and area-deprivation continua from January of 2013 to December of 2018 in Yakima County, Washington. The rates of STIs has been increasing in the United States in the past decade. Historically, Yakima County has higher rates of STIs than state and national rates. In addition, Yakima County contains rural areas and areas with greater deprivation that face gaps in access to care.Methods: The Washington State Department of Health Database Surveillance System was used to conduct the study. The data set included diagnosed cases of chlamydia, gonorrhea, and syphilis with positive laboratory test results for the duration of the study period. Incidence rates of STIs were calculated and statistically analyzed across the urban-rural and area-deprivation continua using rural-urban commuting area codes and the area deprivation index.Results: The incidence rates of STIs increased from January of 2013 to December of 2018. Rates of STI did not differ in micropolitan, small town, and rural block groups compared with the metropolitan block groups. Most-deprived block groups had significantly higher STI rates compared with less deprived block groups.Conclusions: There is a need for increased STI intervention in higher deprivation areas including STI education. Public health officials and health care providers should be aware of these risk factors and tailor interventions to the neighborhood they serve. [ABSTRACT FROM AUTHOR]- Published

Background: We sought to examine the correlates for stimulant use in persons diagnosed with infectious syphilis during an outbreak in Alberta to help guide public health interventions.Methods: Infectious syphilis data were extracted from the Communicable Disease and Outbreak Management database from January 1, 2018, to December 31, 2019. Behavioral, demographic, and lifetime reported stimulant use data were obtained. Descriptive analyses and logistic regression were performed for 3 subpopulations (gay, bisexual, and other men who have sex with men; men who have sex with women; and women).Results: Of 3627 individuals diagnosed with infectious syphilis, 23.9% (n = 867) cases were not interviewed for substance use and were removed from further analysis. Of the remaining 2759 people, 41.8% (n = 1153) self-reported lifetime stimulant use. Gay, bisexual, and other men who have sex with men reported stimulant use less often than women (24.6% vs. 44.1%; P < 0.0001) and men who have sex with women (24.6% vs. 46.2%; P < 0.0001). Multivariable analyses demonstrated that stimulant use was associated with persons who injected drugs, had correctional involvement, or reported multiple sex partners. Men who have sex with women were more likely to self-report First Nations ethnicity (adjusted odds ratio, 1.76 [95% confidence interval, 1.25-2.49]), and women were more likely to have a concurrent gonorrhea infection (adjusted odds ratio, 1.62 [95% confidence interval, 1.15-2.28]).Conclusions: Nearly half of infectious syphilis cases in Alberta reported lifetime nonprescription stimulant use. Infectious syphilis cases with stimulant use were associated with injection drug use, multiple sex partners, and correctional involvement. Our observations highlight the need for integration of sexual health services into programs for people who use substances and those in corrections custody. [ABSTRACT FROM AUTHOR]- Published

Background: The Centers for Disease Control and Prevention (CDC) and US Preventive Services Task Force (USPSTF) guidelines recommend screening for human immunodeficiency virus (HIV) in patients aged 15 to 65 years, as well as those at increased risk. Patients screened in the emergency department (ED) for gonorrhea (GC) and/or chlamydia represent an increased-risk population. Our aim was to assess compliance with CDC and USPSTF guidelines for HIV testing in a national sample of EDs.Methods: We examined data from the 2010 to 2018 Nationwide Emergency Department Sample, which can be used to create national estimates of ED care to query tests for GC, chlamydia, HIV, and syphilis testing. Weighted proportions and 95% confidence intervals (CIs) were reported, and Rao-Scott χ 2 tests were used.Results: We identified 13,443,831 (weighted n = 3,094,214) high-risk encounters in which GC/chlamydia testing was performed. HIV screening was performed in 3.9% (95% CI, 3.4-4.3) of such visits, and syphilis testing was performed in 2.9% (95% CI, 2.7-3.2). Only 1.5% of patients with increased risk encounters received both HIV and syphilis cotesting.Conclusions: Despite CDC and USPSTF recommendations for HIV and syphilis screening in patients undergoing STI evaluation, only a small proportion of patients are being tested. Further studies exploring the barriers to HIV screening in patients undergoing STI assessment in the ED may help inform future projects aimed at increasing guidance compliance.

Introduction: Globally, gay and bisexual men (GBM) are over-represented in HIV, syphilis and gonorrhoea cases. However, surveillance systems rarely provide meaningful measures of inequity, such as population-specific rates, due to a lack of sexual orientation denominators. HIV, gonorrhoea and syphilis are legally notifiable diseases in New Zealand (NZ); we calculate rates by sexual orientation for the first time.Methods: We analysed 2019 national surveillance data on HIV, syphilis and gonorrhoea notifications disaggregated by sexual orientation. Unique health records identified duplicate notifications and reinfections. Missing data were imputed from known cases. We used the NZ Health Survey 2014/2015 to estimate population sizes by sexual orientation, measured in two ways (current sexual identity, sexual contact in the previous 12 months with men, women or both). We calculated notification rates per 100 000 for each sexual orientation subgroup and rate ratios.Results: In 2019, GBM accounted for 76.3%, 65.7% and 39.4% of HIV, syphilis and gonorrhoea notifications, respectively. Population rates per 100 000 for HIV were 158.3 (gay/bisexual men) and 0.5 (heterosexuals); for syphilis, population rates per 100 000 were 1231.1 (gay/bisexual men), 5.0 (lesbian/bisexual women) and 7.6 (heterosexuals); for gonorrhoea (imputed), population rates per 100 000 were 6843.2 (gay/bisexual men), 225.1 (lesbian/bisexual women) and 120.9 (heterosexuals). The rate ratios for GBM compared with heterosexuals were: 348.3 (HIV); 162.7 (syphilis); and 56.6 (gonorrhoea). Inequities remained in sensitivity analysis (substituting sexual identity with sexual behaviour in the previous 12 months).Conclusion: GBM in NZ experience profound inequities in HIV, syphilis and gonorrhoea. Rate ratios by sexual orientation provide useful 'at-a-glance' measures of inequity in disease incidence. [ABSTRACT FROM AUTHOR]- Published

Objectives: This study aimed to determine syphilis coinfection prevalence in people living with HIV (PLHIV) and risk factors for coinfection. Methods: This single-center retrospective cohort study screened PLHIV who were monitored in our center between March 2000 and February 2020 via the hospital’s database and analyzed them by grouping as TPHA-positive and TPHAnegative. TPHA positivity was considered as indicative of Treponema pallidum exposure. Results: The study included 474 PLHIV of whom median age (IQR) was 37 (30-47), and 429 (90.5%) were male. Of the male participants, 206 (47.9%) were MSM. The syphilis coinfection rate was 30.2% (143/474). Among the participants with syphilis coinfection, 80 (16.9%) were found to be coinfected with syphilis at the time of their HIV diagnosis, while 63 (13.3%) got infected with syphilis at a median (IQR) time of 60 (36-84) months into their HIV follow-up and treatment. Syphilis coinfection was related to being male (p<0.001), MSM (p=0.008) and single (p=0.007). Regular condom use was inversely related to syphilis coinfection (p=0.002). Conclusion: HIV and syphilis have similar transmission routes, and HIV and syphilis coinfection is common among men, MSM and people who do not use condoms. PLHIV should be tested regularly for syphilis and informed about risky sexual behaviors and protection methods. [ABSTRACT FROM AUTHOR]

- Abstract
Background: HIV and syphilis are common sexually transmitted infections in sub-Saharan Africa. We aimed to investigate the prevalence and distribution of active syphilis while considering HIV status, demographic characteristics, and behavioural characteristics., Methods: The Population-based HIV Impact Assessment surveys used a cross-sectional, two-stage, stratified cluster sample design to collect data in Ethiopia, Tanzania, Uganda, Zambia, and Zimbabwe from 2015 to 2018. Eligible participants were aged 15 years and older and provided demographic information, behavioural information, and blood specimens for HIV and syphilis testing. Active syphilis was defined as the presence of both treponemal and non-treponemal antibodies, measured using an antigen-based rapid test. Multivariable logistic regression models with survey weights were applied. The estimated number of participants with active syphilis in each country was calculated by multiplying the survey-weighted syphilis prevalence by the corresponding participant population size from the latest national census data. The total burden across the five countries was obtained by summing these estimates., Findings: 102 831 participants enrolled in the five surveys (54 583 [57·6%] participants were female, 48 248 [42·4%] participants were male, 9036 [9·9%] participants were HIV positive). Population-based syphilis prevalence was 0·9% (95% CI 0·7-1·1) in Tanzania and Zimbabwe, 2·1% (1·9-2·4) in Uganda, and 3·0% (2·7-3·4) in Zambia. Overall, an estimated 1 027 615 (95% CI 877 243-1 158 246) participants had active syphilis across the five countries (266 383 HIV-positive and 761 232 HIV-negative individuals). Syphilis prevalence was higher among people living with HIV (range from 2·6% [95% CI 1·1-4·0] in Ethiopia to 9·6% [8·1-11·0] in Zambia) than among those without HIV (range from 0·8% [0·7-1·0] in Tanzania to 2·1% [1·8-2·4] in Zimbabwe). The odds of active syphilis were higher among people living with HIV than in those who were HIV negative (adjusted odds ratio [aOR] range from 2·5 [95% CI 1·8-3·4] in Uganda to 5·9 [3·8-9·2] in Zimbabwe), among divorced, separated, or widowed individuals (aOR range from 1·5 [1·1-2·0] in Uganda to 2·7 [1·7-4·3] in Zimbabwe), and among those reporting two or more sexual partners in the previous 12 months (aOR range from 1·1 [CI 0·8-1·5] in Uganda to 1·9 [1·1-3·3] in Zimbabwe)., Interpretation: This study shows the high burden of syphilis in five sub-Saharan African countries, with a correlation between HIV and active syphilis, underscoring the need for integrated sexual health services and targeted diagnosis, prevention, and treatment strategies to address this public health challenge., Funding: The President's Emergency Plan for AIDS Relief through the US Centers for Disease Control and Prevention., Competing Interests: Declaration of interests We declare no competing interests., (Copyright © 2024 The Author(s).

- Abstract
Based on the distinctive spatial diffusion characteristics observed in syphilis transmission patterns, this paper introduces a novel reaction-diffusion model for syphilis disease dynamics, incorporating general incidence functions within a heterogeneous environment. We derive the basic reproduction number essential for threshold dynamics and investigate the uniform persistence of the model. We validate the model and estimate its parameters by employing the multi-objective Markov Chain Monte Carlo (MCMC) method, using real syphilis data from the years 2004 to 2018 in China. Furthermore, we explore the impact of spatial heterogeneity and intervention measures on syphilis transmission. Our findings reveal several key insights: (1) In addition to the original high-incidence areas of syphilis, Xinjiang, Guizhou, Hunan and Northeast China have also emerged as high-incidence regions for syphilis in China. (2) The latent syphilis cases represent the highest proportion of newly reported cases, highlighting the critical importance of considering their role in transmission dynamics to avoid underestimation of syphilis outbreaks. (3) Neglecting spatial heterogeneity results in an underestimation of disease prevalence and the number of syphilis-infected individuals, undermining effective disease prevention and control strategies. (4) The initial conditions have minimal impact on the long-term spatial distribution of syphilis-infected individuals in scenarios of varying diffusion rates. This study underscores the significance of spatial dynamics and intervention measures in assessing and managing syphilis transmission, which offers insights for public health policymakers., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interest., (Copyright © 2024 The Author(s).

- Abstract
Sexually transmitted infections (STIs) are more commonly seen in patients with human immunodeficiency virus (PWH). Routine sexual history taking and appropriate multisite screening practices support prompt identification and treatment of patients, which in turn reduces morbidity and spread of STIs including HIV. Nucleic acid amplification testing has high accuracy for diagnosing many of the major STIs. Diagnosis of syphilis remains complex, requiring 2 stage serologic testing, along with provider awareness of the myriad symptoms that can be attributable to this disease. Prevention through mechanisms such as vaccines and postexposure prophylaxis hold promise to reduce the burden of STIs in PWH., Competing Interests: Disclosure Dr J. Tuan: no conflicts; Dr W.

- Abstract
In this research, we developed an epidemic model with a combination of Atangana-Baleanu Caputo derivative and classical operators for the hybrid operator's memory effects, allowing us to observe the dynamics and treatment effects at different time phases of syphilis infection caused by sex. The developed model properties, which take into account linear growth and Lipschitz requirements relating the rate of effects within its many sub-compartments according to the equilibrium points, include positivity, unique solution, exitance, and boundedness in the feasible domain. After conducting sensitivity analysis with various parameters influencing the model for the piecewise fractional operator, the reproductive number R0 for the biological viability of the model is determined. Generalized Ulam-Hyers stability results are employed to preserve global stability. The investigated model thus has a unique solution in the specified subinterval in light of the Banach conclusion, and contraction as a consequence holds for the Atangana-Baleanu Caputo derivative with classical operators. The piecewise model that has been suggested has a maximum of one solution. For numerical solutions, piecewise fractional hybrid operators at various fractional order values are solved using the Newton polynomial interpolation method. A comparison is also made between Caputo operator and the piecewise derivative proposed operator. This work improves our knowledge of the dynamics of syphilis and offers a solid framework for assessing the effectiveness of interventions for planning and making decisions to manage the illness., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Saleem et al.

We set out to use routinely collected data from blood donors in Blantyre district, Malawi to explore HIV and syphilis prevalence and identify sero-conversions among repeat donors. We conducted a retrospective cohort analysis of blood donation data collected by the Malawi Blood Transfusion Service from 2015 to 2021. All blood donations were routinely screened for HIV and syphilis. We characterized donor demographics as well as screening outcomes, including identifying sero-conversions among repeat donors who previously tested negative on their last donation. A total of 23,280 donations from 5,051 donors were recorded, with a median frequency of donations of 3 (IQR:2-6). Most donors were male (4,294; 85%) and students (3,262; 64.6%). Prevalence of HIV at first donation was 1.0% (52/5,051) and prevalence of syphilis was 1.6% (80/5,051); 52 HIV sero-conversions and 126 syphilis sero-conversions were identified, indicating an incidence rate per 1,000 person-years of 5.9 (95% CI: 4.7, 7.4) and 13.3 (95% CI:11.4, 15.4) respectively. Students had a lower prevalence of HIV and syphilis but higher risk of syphilis seroconversion. While blood donors are generally considered a low-risk population for HIV and syphilis, we were able to identify relatively high rates of undiagnosed HIV and syphilis infections among donors. Routinely collected data from national blood donation services may be used to better understand local HIV and syphilis epidemiology, with the potential to enhance disease surveillance systems. These findings may be used to identify priority prevention areas and populations in Blantyre district that can inform targeted interventions for improved disease prevention, testing and treatment., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Singogo et al.

- Abstract
Objective: The study aimed to estimate the prevalence of acquired syphilis and associated factors in a national survey., Methods: TransOdara was a cross-sectional study comprising transgender women and travestis (TGW) in five major cities in Brazil during December of 2019 and July of 2021. The sample was recruited using the respondent-driven sampling (RDS) method. The outcome "active syphilis" was defined as a positive treponemal test and Venereal-Disease-Research-Laboratory (VDRL) title greater than∕ equal to ⅛. Sociodemographic variables were described. Bivariate and multiple logistic regression were performed, and odds ratios (OR) and 95% confidence intervals (95%CI) were estimated. All analyses were performed in R, 4.3.1., Results: A total of 1,317 TGW were recruited, with 1,291 being tested for syphilis, and 294 (22.8%) meeting the criteria for active syphilis. In bivariate analysis, black/mixed race (OR=1.41, 95%CI 1.01-1.97), basic level of education (OR=2.44, 95%CI 1.17-5.06), no name change in documents (OR=1.39, 95%CI 1.00-1.91) and sex work (past only OR= 2.22, 95%CI 1.47-3.32; partial OR=2.75, 95%CI 1.78-4.25; full time OR=3.62, 95%CI 2.36-5.53) were associated with active syphilis. In the multivariate analysis, sex work was the only associated factor, 2.07 (95%CI 1.37-3.13) past sex work, 2.59 (95%CI 1.66-4.05) part-time sex work and 3.16 (95%CI 2.04-4.92) sex work as the main source of income., Conclusion: The prevalence of active syphilis in this study was elevated compared with other countries in Latin America. Sex work was an important associated factor with active syphilis, highlighting the impact that this condition of vulnerability may have in the health of TGW, as members of a key, marginalized population.

- Abstract
Objective: To investigate the prior testing for HIV, syphilis, hepatitis B (HBV), and hepatitis C (HCV) among transgender women and travestis (TGW) in five Brazilian cities and identify factors associated with each of these previous tests., Methods: This is a cross-sectional study with the recruitment of TGW through respondent-driven sampling (TransOdara Study). The investigated outcome variable was prior testing for HIV, syphilis, HBV, and HCV in the last 12 months. The association between sociodemographic and behavioral factors with the outcome was analyzed using a binomial logistic regression with mixed effects. Adjusted odds ratios (aOR) and 95% confidence intervals (CI95%) were estimated., Results: The proportions of individuals with prior testing in the past year were as follows: 56.3% for HIV, 58.0% for syphilis, 42.1% for HBV, and 44.7% for HCV. Negative associations with prior testing were observed for individuals aged 35 years or older, whereas positive associations were found for those with high school education, those who experienced verbal or psychological violence in the last 12 months, and those who had commercial or casual partners in the last 6 months., Conclusion: There was low frequency of testing in the 12 months preceding the study for HIV, syphilis, HBV, and HCV compared to the guidelines established by the Ministry of Health. Expanding access to and engagement with healthcare and prevention services for TGW is an essential strategy in reducing the transmission chain of HIV and other sexually transmitted infections (STIs).
