Risk Factors For Syphilis Research Articles

Analysis of 2019 Ohio Disease Intervention Specialist (DIS) Records for Syphilis Cases Using Clustering Algorithms.

Developments in natural language processing (NLP) and unsupervised machine learning methodologies (e.g., clustering) have given researchers new tools to analyze both structured and unstructured health data. We applied these methods to 2019 Ohio disease intervention specialist (DIS) syphilis records, to determine whether these methods can uncover novel patterns of co-occurrence of individual characteristics, risk factors, and clinical characteristics of syphilis that are not yet reported in the literature. The 2019 DIS syphilis records (n=1,996) contain both structured data (categorical and numerical variables) and unstructured notes. In the structured data, we examined case demographics, syphilis risk factors, and clinical characteristics of syphilis. For the unstructured text, we applied TF-IDF (term frequency multiplied by inverse document frequency) weights, a common way to convert text into numerical representations. We performed agglomerative clustering with cosine similarity using the CLUTO software. The cluster analysis yielded six clusters of syphilis cases based on patterns in the structured and unstructured data. The average internal similarities were much higher than the average external similarities, indicating that the clusters were well-formed. The factors underlying three of the clusters related to patterns of missing data. The factors underlying the other three clusters were sexual behaviors and partnerships. Notably, one of the three consisted of individuals who reported oral sex with male or anonymous partners while intoxicated, and one was comprised mainly of males who have sex with females. Our analysis resulted in clusters that were well-formed mathematically, but did not reveal novel epidemiological information about syphilis risk factors or transmission that were not already known.

Incidence and risk factors associated with acquired syphilis in HIV pre-exposure prophylaxis users.

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. 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). 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). 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.

Risk Factors of Syphilis Infection among Female Sex Workers (FSW) in Indonesia 2018/2019: A Cross Sectional Study

Background: Syphilis is one of the most common causes of curable bacterial sexually transmitted infection (STI) worldwide. Female sex workers (FSW) are the key population to be affected by STI. in Indonesia, little is known about syphilis infection in most at risk population. This study aimed to know the risk factors of syphilis among FSW in Indonesia 2018-219.Methods: This research uses Cross Sectional study design. This study used secondary data based on the Integrated Biological and Behaviour Survey (IBBS) 2018-219. The study population was 5,816FSWs who registered in the IBBS 2018-2019 in 16Districts/Municipalities in Indonesia. The study sample was derived from an eligible population that met the inclusion criteria=5,647 respondents.Results: The results show the prevalence of Syphilis among FSW was 1.3%. Syphilis infection is associated tocondom consistent (OR=1.7 ; 95%CI=1.094– 2.853 and STI Information (OR=1.7; 95%CI=1.115–1.788).Conclusion: FSWs who do not use condoms consistently and correctly when having sex with customers and those who do not receive health information about syphilis are at higher risk of syphilis infection. For this reason, FSWs must use condoms consistently and correctly every time they have sex with customers.

Prevalence of syphilis and associated risk factors among human immunodeficiency virus-infected patients at the Lagos University Teaching Hospital Nigeria: A cross-sectional study

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.

Global, regional, and national burden of syphilis, 1990-2021 and predictions by Bayesian age-period-cohort analysis: a systematic analysis for the global burden of disease study 2021.

To comprehensively assess the global burden of syphilis and related risk factors over 1990-2021, forecast future disease trends, and understand the impact of syphilis on global health. Global Burden of Disease Study 2021 (GBD 2021) data were used for age-, sex-, and region-stratified analysis of the numbers and age-standardized rates (per 100,000 population) of syphilis incidence, prevalence, deaths, and disability-adjusted life years (DALYs). Next, a differential analysis of syphilis risk factors was performed. Finally, trends for years after 2021 were predicted using Bayesian age-period-cohort (BAPC) prediction models. In 2021, the total number of syphilis prevalence globally was 70,541,482.80 (95% uncertainty interval: 54,910,897.66-88,207,651.97), with the highest numbers noted in Central Sub-Saharan Africa [4,622.60 (95% uncertainty interval: 3,591.97-5,753.45)]. Over 1990-2021, the global age-standardized prevalence and incidence rates increased, whereas the age-standardized death and DALY rates decreased. Among all groups, infants aged <5 years demonstrated the highest age-standardized DALY rates. Moreover, the lower the sociodemographic index (SDI), the higher was the age-standardized rate. The primary factor contributing to syphilis disease burden was identified to be unsafe sex. BAPC analysis revealed an overall increase in age-standardized prevalence rate in the <5-year age group over 1990-2035, and the highest age-standardized prevalence rate occurred in the 25-34-year age group. Between 1990 and 2021, syphilis occurrence and prevalence increased consistently. Projections indicated a continual increase in syphilis incidence in children aged <5 years, and age-standardized prevalence rates were the highest in adults aged 25-34 years. Our results regarding the epidemiological trends of syphilis and its variations across regions, age groups, and sexes may aid policymakers in addressing the global impact of the disease effectively.

Profile of Syphilis Risk Factors in The Productive Age Group at Dermatology and Venereology Clinic RSUD DR. Saiful Anwar, Malang Indonesia

Syphilis is a sexually transmitted infection that has the potential to cause serious complications and is closely related to the human immunodeficiency virus (HIV) infection, thus making syphilis a major public health problem. Understanding the characteristics of risk factors could be used to prevent future transmission and occurrences of syphilis. This study aimed to determine the demographic data and risk factors of syphilis in productive age at the Dermatology and Venereology Clinic, RSUD. DR. Saiful Anwar, Malang, Indonesia. This study used a descriptive approach using secondary data from the medical records of syphilis patients from January to December 2021. Sample collection was carried out using a total sampling technique. Twenty medical records that met the inclusion criteria were included, all of which belonged to the productive age group. The majority of the sample were male (70%), aged 17-25 years (45%) and 26-35 years (45%), had a high school education (55%), were private sector workers (40%), were unmarried (70%), had anogenital sexual activity (50%), never used condoms (50%), had more than one sexual partner (85%), were in the primary stage of syphilis (35%), and were HIV positive. Among male patients with syphilis-HIV coinfection, 80% of cases were homosexual. The risk factors for syphilis at a productive age include anogenital intercourse, irregular condom use, multiple sexual partners, the primary stage of syphilis, HIV infection, and homosexuality. A program focused on detecting and treating syphilis among people living with HIV/AIDS, especially those in high-risk populations such as men who have sex with men (MSM), is needed.

Epidemiological characteristics and risk factors of syphilis among blood donors in Huzhou.

To investigate the epidemiological characteristics and risk factors for syphilis in Huzhou City, and to provide data to support the design of more effective health counselling and screening measures for blood donors. A retrospective study was conducted to analyse the demographic characteristics and seropositivity of syphilis among blood donors from 2019 to 2021. The differences in the serological status of syphilis among different populations under different demographic factors were compared, and conditional logistic regression analysis was used to identify the risk factors for syphilis. The seropositivity rate of syphilis among blood donors in Huzhou City was 133/100,000, which decreased year by year. There were significant differences in the syphilis seropositivity rate among different groups in terms of age, education level, occupation, household registration, marital status and blood donation history (P<0.05). The multivariate logistic regression model showed that all six factors, including age, education level, occupation, household registration, marital status and blood donation history, had significant effects on syphilis infection (P<0.01), with OR values and 95% CIs of 2. 387 (1.381-4.127), 3.607 (1.609-8.086), 2.784 (1.657-4.679), 5.074 (1.865-13.804), 11.177 (3.481-35.888), and 11.244 (3.940-32.091), respectively. There is room for improvement in pre-donation health counselling and screening of high-risk populations. Timely monitoring and updating of demographic data for specific high-risk populations is essential.

Prevalence of syphilis in HIV-infected patients with transmission risk and influencing factors in Zhejiang Province

Objective: To investigate the prevalence of syphilis in HIV-infected patients with transmission risk and influencing factors in Zhejiang Province. Method: The information about the HIV-infected patients, who were alive, had been diagnosed with HIV for >1 year, had received no antiviral treatment or had HIV viral load ≥50 copies/ml, and were aged ≥15 years, reported in Zhejiang as of December 31, 2018 were collected from China Information System for Disease Control and Prevention. The information included general demographic characteristics, sexual behavior characteristics and antiretroviral therapy and syphilis serological test results. The prevalence of syphilis and the influencing factors were analyzed by logistic regression model. The SPSS 19.0 software was used for statistical analysis. Results: A total of 2 275 HIV-infected patients were at risk of HIV transmission, and 75.5% (1 717/2 275) of them were tested for syphilis, the prevalence rate of syphilis was 8.7% (150/1 717). Among the HIV-infected patients with syphilis, 11.3% (17/150) received no antiviral treatment, 38.7% (58/150) had viral load of 50-999 copies/ml and 50.0% (75/150) had ≥1 000 copies/ml. Multivariate logistic regression analysis showed that being men (aOR=2.04, 95%CI:1.06-3.96), homosexual transmission (aOR=1.53, 95%CI:1.04-2.27), history of sexually transmitted diseases (STDs) before HIV diagnosis (aOR=1.98, 95%CI:1.35-2.92) and HIV viral load ≥1 000 copies/ml (aOR=1.90, 95%CI:1.09-3.30) were the risk factors for syphilis. Marriage (aOR=0.47, 95%CI: 0.29-0.76) was a protective factor for syphilis. Conclusions: The prevalence of syphilis was high in HIV-infected patients with transmission risk in Zhejiang. It is urgent to carry out classified management and targeted intervention in HIV-infected patients, explore multi-disease prevention and treatment mechanism, strengthen syphilis screening and treatment in HIV-infected patients to reduce the transmission of HIV and syphilis.

HIV ve Sifilis Koinfeksiyonu Olan Hastaların İrdelenmesi

Introduction: Coinfections of human immunodeficiency virus (HIV) and syphilis can be seen due to reasons such as common risk group and transmission routes. In our study, it was aimed to investigate the seroprevalence of syphilis and the clinical features of the patients living with HIV. Materials and Methods: Data of 277 HIV-infected patients in Health Sciences University Umraniye Education and Research Hospital between January 2016 and December 2021 were evaluated retrospectively. Results: A total of 277 patients living with HIV were included in the study. Two hundred thirty-five (85%) of the patients were male and the mean age was 42.86 ± 13.40 years. HIV/syphilis coinfections were detected in 15% of newly diagnosed HIV patients and 25% during follow-up period. Among patients with HIV/syphilis coinfection 94% of patients were in the latent stage of syphilis, 6% of them were in the secondary stage. Neurosyphilis was diagnosed in one patient. The rate of syphilis was found to be statistically significantly higher in male, and alcohol-consuming patients. In heterosexual cases, the rate of not detecting syphilis was statistically significant. Conclusion: In our region, HIV/syphilis seroprevalence was found to be 25% during the study period. Syphilis coinfection was found to be statistically significant in male, and alcohol-consuming patients living with HIV. Considering the increasing seroprevalence of syphilis and HIV co-infection in the world, close follow-up of patients with HIV-infected risk factors for syphilis is recommended.

High Prevalence of Syphilis and Syphilis/HIV Coinfection among Men Who Have Sex with Men Who Attend Meeting Places in Mexico.

Men who have sex with men (MSM) are disproportionately affected by syphilis, HIV, and syphilis/HIV coinfection. Antiretroviral therapy (ART) prevents HIV transmission but does not impede the spread or acquisition of syphilis. Information about syphilis/HIV coinfection among MSM is scarce. We aimed to determine the prevalence of syphilis/HIV coinfection in a national sample of MSM who attend meeting places (such as movies, clubs, gay bars, saunas, shopping malls, and others referred to by the same MSM participants of the study) in Mexico to evaluate factors associated with syphilis, and to compare the prevalence rates of syphilis between the current survey and DGE data. We performed a laboratory diagnosis to determine the rates of syphilis and HIV among the included MSM. The national and regional prevalence of syphilis was calculated. HIV and coinfection prevalence were determined only for the survey. All prevalence rates included 95%CIs. Descriptive, bivariate, and multivariate analyses were performed. The national prevalence rates of syphilis, HIV, and coinfection were 15.2%, 10.2%, and 5.7%, respectively. The region with the highest prevalence rate was Mexico City (39.4%). The center region, minimal "goods" (i.e., a minimal number of material possessions such as a car or dryer, etc., which served as a proxy for low economic income level), use of "inhalant drugs", "HIV infection", "sexual intercourse" only with men, "rewarded sex", and "youngest age at first sexual encounter or debut" were risk factors for syphilis. In general, regional prevalence of syphilis was higher in the survey (2013) and DGE data from 2019 than in the DGE data from 2013. Similar to other countries, Mexico needs to assess elements around not only syphilis and HIV infections but also syphilis/HIV coinfection, and preventive measures focusing on MSM are needed.

Incidence and Risk Factors for Early Syphilis Among Men Who Have Sex With Men in Australia, 2013-2019: A Retrospective Cohort Study.

We aimed to examine the incidence of syphilis in men who have sex with men (MSM) and identify subgroups of MSM at a higher risk of syphilis infection. We conducted a retrospective cohort study of MSM attending a sexual health clinic in Australia, during 2013-2019, who had at least 2 syphilis serological tests during the study period. The incidence of syphilis was expressed as per 100 person-years. A cox regression analysis was conducted to identify risk factors for syphilis. A total of 24 391 individual MSM (75 086 consultations) were included. A total of 1404 new syphilis cases were diagnosed with an incidence of 3.7/100 person-years (95% confidence interval, 3.5-3.9). Syphilis incidence was higher in MSM with human immunodeficiency virus ([HIV] 9.3/100 person-years) than in MSM taking HIV pre-exposure prophylaxis (PrEP) (6.9/100 person-years) or HIV-negative MSM not taking PrEP (2.2/100 person-years). Risk factors associated with high incidence of syphilis included the following: MSM with HIV (adjusted hazard ratio [aHR] 2.7), MSM taking HIV PrEP (aHR 2.1), past history of syphilis infection (aHR 2.4), injecting drug use (aHR 2.7), condomless anal sex (aHR 1.7), >4 sexual partners in the last 12 months (aHR 1.2), and concurrent sexually transmitted infection (chlamydia and gonorrhoea) (aHR 1.6). The incidence of syphilis remains high among MSM, particularly in subgroups with associated risk factors for syphilis infections. These data highlight the need for biomedical and behavioral interventions to be targeted to subgroups of MSM at the highest risk of syphilis infection.

Prevalence of syphilis and risk factors among HIV-positive men who have sex with men in Guangdong province.

HIV-positive men who have sex with men (MSM) tend to have high syphilis incidence. Our objective is to evaluate the prevalence of syphilis and determine the risk factors of syphilis among HIV-positive MSM. A cross-sectional study with convenience sampling was performed among HIV-positive MSM in six cities of Guangdong Province from June 2020 to August 2021. Participants completed a survey including social-demographic characteristics, sexual behaviors and self-reported syphilis, chlamydia, gonorrhea, herpes, human papillomavirus statuses after HIV diagnosis. Multivariate logistic regression was used to determine the factors associated with syphilis and sexually transmitted diseases (STD). Among 944 HIV-positive MSM, 141 (14.9, 95% CI: 12.7-17.2%) men had syphilis and 220 (23.3, 95% CI: 20.6-26.0%) men had STD. Multivariate analysis indicated that MSM who met male sexual partners mainly through traditional meeting places (spa or bath house, sauna, foot or body massage parlor) in the last 6 months [adjusted Odds Ratio (aOR) = 2.91, 95% CI: 1.09-7.79], and who were diagnosed with herps after the HIV diagnosis (aOR = 3.79, 95% CI: 1.16-12.39) were more likely to have syphilis. In addition, MSM who met male sexual partners mainly through traditional meeting places in the last 6 month (aOR = 2.55, 95% CI: 1.01-6.42), and who had more than one male sexual partner in the last 6 months (aOR = 1.88, 95% CI: 1.17-3.02) were more likely to have STD. The prevalence of syphilis and other STDs is relatively high among HIV-positive MSM in southern China. Routine syphilis screening as a part of HIV monitoring among HIV-positive MSM will have important epidemiological significance for the management of infected patients, and can help reduce the spread of syphilis.

Risk Factors of Syphilis and HIV/AIDS Coinfection

Background: Syphilis infection and HIV are major health problems worldwide. Both of these diseases can be transmitted through sexual contact, so often a person suffers from both diseases at the same time. Purpose: To describe the risk factors of syphilis and HIV/AIDS coinfection in the Infectious Disease Intermediate Treatment Unit (UPIPI) inpatient and outpatient ward of Dr. Soetomo General Academic Hospital in 2019. Methods: The study design used in this study is a retrospective descriptive study aimed at evaluating sexual and non-sexual factors that cause syphilis and HIV coinfection. The research population was patients in the inpatient and outpatient rooms of UPIPI RSUD Dr. Soetomo Surabaya for the January-December 2019 period. The sampling technique was sourced from secondary data, namely medical record data from the inpatient and outpatient rooms of UPIPI RSUD Dr. Soetomo Surabaya for the period January-December 2019. The data in this study were obtained from medical records and patient biodata. Result: Based on the calculation results, it is known that age group (P=0.022&gt;0.05), and gender (P=0.024&gt;0.05) had no effect on the risk of syphilis and HIV coinfection, while marital status (P=0.048&lt;0.05), sexual orientation (P=0.048&lt;0.05), transmission model (P=0.044&lt;0.05), and type of work (P=0.046&lt;0.05fected the risk of syphilis and HIV coinfection. Conclusion: People with HIV/AIDS are expected to be active in participating in programs that are needed by patients, such as antiretroviral (ARV) therapy assistance programs and counseling that will prolong the quality of life in various aspects of life, both physical, psychological and social aspects.

Risk Factors for Syphilis at a Large Urban Emergency Department.

The prevalence of syphilis is increasing in the United States. The emergency department (ED) is an important setting to screen and treat underserved populations. To tailor testing protocols to the local population, we aimed to identify risk factors for syphilis positivity in ED patients. We performed a retrospective analysis of ED patients who were screened for syphilis between November 2018 and August 2020. Patients were screened for Treponema pallidum antibody using a multiplex flow immunoassay, and positive results were confirmed by rapid plasma reagin or T. pallidum particle agglutination. Risk factors for new syphilis diagnoses were identified using multiple logistic regression. We screened 1974 patients for syphilis (mean age, 37 ± 16 years; 56% female). We identified 201 patients with new infections without previous treatment. Independent risk factors for a new diagnosis of syphilis included housing status (undomiciled, 23% [60 of 256]; domiciled, 9% [133 of 1559]; adjusted odds ratio [aOR], 1.9 [95% confidence interval {CI}, 1.2-3.0]), history of HIV (positive, 44% [28 of 63]; negative, 9% [173 of 1893]; aOR, 5.8 [95% CI, 3.0-11.2]), tobacco use (positive, 15% [117 of 797]; negative, 4% [29 of 665]; aOR, 2.4 [95% CI, 1.5-3.9]), and illicit drug use (positive, 14% [112 of 812]; negative, 8% [52 of 678]; aOR, 2.2 [95% CI, 1.0-2.5]). Undomiciled housing status, history of HIV, history of tobacco use, and history of illicit drug use were independently associated with a new diagnosis of syphilis in the ED. Broadening targeted syphilis screening algorithms beyond sexually transmitted disease-related complaints could help identify new syphilis cases for treatment.

High prevalence of syphilis in women, minors and precarious patients: a cross-sectional study in a Reunion Island sexually transmitted infection clinic, 2017-2020.

Syphilis is a sexually transmitted infection (STI) with a global prevalence estimated at 0.5% in 2012. Syphilis has been on the rise among men who have sex with men (MSM) in high-income countries and remains at endemic levels in low- and middle-income countries. This trend, however, has not been observed in Reunion Island. To determine the prevalence, clinical characteristics and risk factors of syphilis in at-risk patients visiting the South Reunion STI clinic in Reunion Island. This monocentric cross-sectional study included all patients who visited our STI clinic between 2017 and 2020. Syphilis serology was performed on all included patients, and data were collected using a standardized self-administered questionnaire. Over the 3-year study period, 2593 patients were enrolled. The prevalence of syphilis was 7.52% (n=195, 95% CI, 6.50-8.65%) in the overall study population, 11.76% (n=18, 95% CI, 6.97-18.59%) in minors (aged under 18years) and 36.36% (n=16, 95% CI, 21-59%) in pregnant women. The risk factors identified in multivariate analysis were being female [adjusted Prevalence Ratio (aPR) 1.85, 95% CI, 1.10-3.11], being MSM (aPR 2.87, 95% CI, 1.71-4.80), being aged under 18years (aPR 3.54, 95% CI, 1.90-6.57), living in precarious conditions [aPR 3.12, 95% CI, 2.11-4.62] and being born in Reunion Island (aPR 2.43, 95% CI, 1.42-4.13). The clinical presentation was heterogeneous (plaques and papules, chancre, atypical ulcerations, multiple ulcerations, condyloma lata, etc.). These findings suggest a high prevalence of syphilis in at-risk patients visiting our STI clinic. Unlike the situation in other high-income countries, the people most at risk of syphilis in Reunion Island are local-born residents, minors, women and precarious patients. This is a source of concern, especially given the risk of resurgence of congenital syphilis on the island.

Prevalence and Factors Associated With Syphilis in People Living With HIV/AIDS in the State of Pará, Northern Brazil.

Syphilis continues to be a public health problem worldwide and its incidence has increased in people living with HIV/AIDS in recent years. This study determined the prevalence and factors associated with syphilis in people living with HIV/AIDS in the city of Belém, northern Brazil. A cross-sectional study was conducted from June to November 2018. A total of 500 people living with HIV/AIDS attended at a specialized unit of the public health network of the State of Pará were studied. Questionnaires were used to collect socio-demographic data and potential risk factors for syphilis. Blood samples were collected from all subjects and screened for syphilis using VDRL, and the seropositive were confirmed using FTA-abs. Logistic regressions were used to identify the factors associated with syphilis. Most subjects were male (56.8%), had more than 40 years (54.0%), single (63.0%), had finished high school (54.2%), had monthly income ≤1 minimum wage (72.4%), and had been born to the city of Belém (59.8%). Prevalence of syphilis was 6.4%. Eight characteristics/behaviors associated with syphilis: male, young adults, single, studied at least high school, monthly income >1 minimum wage, homosexual/bisexual, does not use or sporadically use condoms during sexual intercourse, and have had more than one sexual partner in the last three months. The prevalence of syphilis in people living with HIV/AIDS in Belém is low when compared to other Brazilian states. However, there is a need for public policies and actions to monitor, control and prevent these two sexually transmitted infections.

Serosurvey of anti-treponema pallidum (syphilis), anti-hepatitis C virus and anti-HIV antibodies in homeless persons of São Paulo city, southeastern Brazil

Homeless persons have been considered as one of the most susceptible populations to sexually transmitted infections. In Brazil, these population experienced an increase of 140% from 2012 to 2020. Accordingly, the present study aimed to assess the seroprevalence of anti-Treponema pallidum, anti-HCV, anti-HIV antibodies, and the risk factors associated with homeless persons in a daytime attendance shelter of São Paulo city during the syphilis epidemic in Brazil. Blood samples of 116 volunteers and epidemiological data were conveniently collected in the shelter from June through August 2018. Detection of syphilis, HCV, and HIV antibodies was performed by chemiluminescent microparticle immunoassay (CMIA). CMIA-reagent samples for anti-T. pallidum antibodies were confirmed by Venereal Disease Research Laboratory (VDRL) non-treponemal test. VDRL non-reagent samples were confirmed by treponemal rapid immunochromatographic test. A rapid immunoblot assay confirmed seropositivity to HIV. Overall, anti-T. pallidum antibodies were observed in 29/116 (25.0%), anti-HCV antibodies in 4/116 (3.4%), and anti-HIV antibodies in 2/116 (1.7%) individuals, both co-infected with anti-T. pallidum antibodies. Associated risk factors for syphilis in homeless persons were being born or previously living in another city (p = 0.043) and becoming homeless due to family conflicts (p = 0.035). Besides homeless vulnerability, worldwide shortage of benzathine penicillin supply and increasing of syphilis testing access through rapid testing in primary health care services may have also impacted disease spreading at the time. The prevalence of syphilis found herein is the highest worldwide to date in this population.

Seroprevalence and Risk Factors of Syphilis among Blood Donors

Abstract &#x0D; Background: Transfusion of blood /component is an essential procedure in modern days of medical practice. As far as safe transfusion is concerned, it is a prime requirement i.e. handles TTIs infections including syphilis and other adverse events.&#x0D; Aims and Objectives: Focus of the present study is to assess seroprevalence and risk factors of Syphilis among blood donors in greater Gwalior&#x0D; Materials and Methods: The present retrospective descriptive study was conducted over a period of 8 years. All the samples of voluntary and relative blood donors, who came to donate blood, were tested for transfusion transmissible infections. Prevalence of TTIs and syphilis were analyzed in the view of different parameters of donors and along with its associated risk factors. Chi square (X2) test was applied to know the significant (p value) ratio of difference statistically as required.&#x0D; Results: In the present study prevalence of TTIs is 3.44% and for syphilis it is 0.268%, most common age group is 40-51years (41.18%); male to female ratio is insignificant statistically. Ratio of voluntary versus relative donors was 94.21% and 5.79 % and male to female was 91.27% and 8.473% were female respectively.&#x0D; Conclusion: An advance knowledge, attitude, and behavior of the volunteer blood donors’ population regarding risk factors will most probably improve public health and increase blood safety and quality.
