Seroinfection of Antibodies to Toxoplasma gondii, Parvovirus B19, Treponema pallidum, and HIV in a Pregnant Attending a Medical Center in Northern Peru. Infect Dis Obstet Gynecol 2024; 2024:8844325. [PMID: 38883209 PMCID: PMC11178423 DOI: 10.1155/2024/8844325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2023] [Revised: 03/23/2024] [Accepted: 05/02/2024] [Indexed: 06/18/2024] Open
Abstract
Introduction Transplacental infections are frequent, especially in developing countries, where limited screening is performed to find infectious agents in the pregnant population. We aim to determine the clinical and epidemiological characteristics and seroinfection of antibodies against Toxoplasma, parvovirus B19, T. pallidum, and HIV in pregnant women who attended the Motupe Health Center in Lambayeque, Peru during July-August 2018. Methods A descriptive cross-sectional study was conducted in 179 pregnant women interviewed with a standardized questionnaire. ELISA was used to determine antibodies to Toxoplasma and parvovirus B19. The detection of syphilis and HIV was conducted using immunochromatography, while the detection of hepatitis B was conducted using FTA-ABS and immunofluorescence, respectively. Results Of 179 pregnant women, syphilis and HIV infections routinely included in the screening of pregnant women presented a seroinfection of 2.2 and 0.6%, respectively. Toxoplasmosis seroinfection was 25.1%, while IgM antiparvovirus B19 was 40.8%, revealing that pregnant women had an active infection at the time of study. Conclusion The level of seroinfection of toxoplasmosis reveals the risk to which pregnant women who participated in the study are exposed. The high seroinfection of parvovirus B19 could explain the cases of spontaneous abortion and levels of anemia in newborn that have been reported in Motupe, Lambayeque, Peru. However, future causality studies are necessary to determine the significance of these findings.

Seroprevalence of Treponema pallidum infection in Brazilian indigenous people: a cross-sectional study. Sci Rep 2024; 14:11822. [PMID: 38782949 PMCID: PMC11116400 DOI: 10.1038/s41598-024-59369-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Accepted: 04/09/2024] [Indexed: 05/25/2024] Open
Abstract
Indigenous communities in Brazil have a complex epidemiological profile, which increases their chances of contracting sexually transmitted diseases. However, limited data is available on Treponema pallidum infections in this population. We investigated the seroprevalence and risk factors associated with T. pallidum infection in an indigenous population of Dourados, Mato Grosso do Sul. Blood samples were collected from September 2017 to March 2020, and the participants were interviewed to obtain comprehensive data on demography and sexual behavior. Serological tests were performed to detect T. pallidum infection. Besides conducting descriptive analysis, we performed Chi-squared tests and determined the bivariate odds ratio. The data were also analyzed using logistic regression. Among the 2190 invited individuals, 1927 (88%) were included in this study. The seroprevalence of T. pallidum infection was 2.91%. The results of a multivariate analysis showed that individuals who were 30-39 years old, with up to 4 years of school education, living in households without piped water, with a history of genital lesions, multiple sexual partners, and having a history of STIs had the highest seroprevalence of T. pallidum. This study showed that behavioral, social, and economic factors play an important role in the transmission of T. pallidum within the indigenous population. Thus, targeted intervention, including imparting education in the native language, mass testing initiatives, and implementing public policies to improve socioeconomic indicators, is needed to reduce the cases of syphilis in this community.

[PMID: 36875380 PMCID: PMC9982104 DOI: 10.3389/fpubh.2023.1082637] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Accepted: 01/30/2023] [Indexed: 02/19/2023] Open
Abstract
Background In China, the HIV/AIDS epidemic among men who have sex with men (MSM) has been expanding in recent years. Substance abuse in MSM was not well studied as the independent risk factor for HIV and syphilis infection and other sexually transmitted diseases. The present review aimed to determine the correlation between HIV/Syphilis infections and substance abuse and other sexual risk behaviors among MSM. Methods We conducted a comprehensive search of PubMed, Web of Science, Embase, Scopus, Chinese National Knowledge Infrastructure, Chinese Wanfang Data, and VIP Chinese Journal Database for relevant articles of quantitative studies published between 2010 and May 31, 2022. Meta-analysis was performed using R software. Pooled estimated of the association-odds ratio, with 95% confidence intervals were calculated using random-effects models stratified by study design. Q statistics and I2 were used to measure the heterogeneity. Results Our meta-analysis included 61,719 Chinese MSM from 52 eligible studies. The pooled HIV prevalence rate among substance-abusing MSM was 10.0% (95% CI = 0.08-0.13). Substance abusers were more likely to have a higher prevalence of HIV (OR = 1.59) and syphilis (OR = 1.48) infections than non-substance abusers. Substance abusers were also more likely to seek sexual partners through the internet or social media applications (OR = 1.63), engage in unprotected anal intercourse (UAI) (OR = 1.69), group sex (OR = 2.78), and engage in commercial intercourse (OR = 2.04) compared to non-users. Regarding testing behaviors, substance abusers had a higher proportion of HIV or STI testing in their lifetime (OR = 1.70) compared with non-substance abusers (p < 0.05). They were also more likely to have had more sexual partners (≥2; OR = 2.31) and more likely to have consumed alcohol (OR = 1.49) in the past 6 months. Conclusions Our study shows the correlation between substance abuse and HIV/Syphilis infection. Eliminating disparities in HIV/Syphilis infection among substance abusing men who have sex with men (MSM) can be achieved if the Chinese government and public health sectors could provide targeted knowledge popularization and diagnosis interventions among high-risk populations.

Abstract
Background People living with HIV (PLWH) are at an increased risk of syphilis infection. The objectives of this study were to assess the overall prevalence of syphilis among PLWH in China and identify factors associated with syphilis infection among PLWH. Methods We searched Medline, Embase, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journals Database (VIP), Wan-fang Data, and Chinese Biomedical Literature Database (CBM) to identify studies that reported the prevalence of syphilis among PLWH in China and were published in English or Chinese from January 1, 1990, to May 31, 2022. The reference lists of retrieved articles and relevant reviews were also checked to identify additional studies. A random-effect model was fitted to calculate the pooled syphilis prevalence among PLWH. Subgroup analyses, meta-regression analyses and sensitivity analyses were conducted to determine the potential source of heterogeneity. Results Of the 1,599 articles screened, 29 studies involving 34,740 participants were eligible for inclusion in this meta-analysis. The overall prevalence of syphilis among PLWH in China was 19.9% [95% confidence interval (CI): 15.4-24.8%, I 2 = 98.9%]. Subgroup analysis showed that the pooled prevalence of syphilis among men who have sex with men (MSM) with HIV (21.9%, 95% CI: 17.2-26.9%) was much higher than that among heterosexuals (10.3%, 95% CI: 5.2-16.8%); there was regional diversity in the prevalence of syphilis, the highest in northern China (31.7%, 95% CI: 17.9-47.4%), followed by central-southern China (26.7%, 95% CI: 11.4-45.7%), and the lowest in northwestern China (15.0%, 95% CI: 6.9-25.4%); the syphilis prevalence among PLWH decreased as CD4 + T cell count increased (19.6% in CD4 + T cell < 200 vs. 8.7% in ≥ 500) and was higher among non-antiretroviral therapy (non-ART) HIV-infected patients (21.0%, 95% CI: 9.9-35.0%) than that among ART ones (16.1%, 95% CI: 3.9-34.3%). Conclusions Our study showed a significantly high prevalence of syphilis among PLWH in China, particularly among MSM with HIV. Developing national guidelines for the integrated screening, monitoring, and management of HIV and syphilis as well as syphilis diagnosis and treatment training programs for physicians at designated HIV treatment hospitals is urgent and crucial to combat HIV and syphilis coinfection in China.

Abstract
Background New HIV diagnoses are rising in Turkiye. Men who have sex with men (MSM) are estimated to be the main driver of the epidemic. Pre-exposure prophylaxis (PrEP) was proven to be effective in reducing new HIV diagnoses and PrEP recently became available in Turkiye. Objective To assess awareness of and willingness to use PrEP and the level of off-licence use among MSM. Methods An anonymous self-completed questionnaire was sent out over the Hornet Gay Social Network from December 2019 to February 2020, available in Turkish and Arabic. It included 20 questions on HIV and STI testing, PrEP awareness, PrEP use, willingness to use, chemsex and sexual happiness level. Results Overall 4761 respondents who responded to more than 1/3 of the questions were eligible for analyses; 5.5% was Arabic speaking. The mean age was 30.5 years, 31.4% had never tested for HIV, 40.5% knew what PrEP was, the most common source of knowledge was the internet (44.5%), 2.5% (120) had used PrEP in the last 12 months and 1.7% (83) was current users. PrEP users had accessed drugs over the internet (47.6%), pharmacy (23%), and friends (13.8%). Almost 40% were willing to use PrEP in the following 6 months. Younger and Arabic speaking respondents had lower rates of HIV testing ( p = .001) and lower awareness for PrEP than comparators ( p = .004). Conclusion Awareness and willingness to use PrEP is high among MSM in Turkiye. The recent availability of PrEP in the country is a big step forward in terms of prevention.

Abstract
Background In the past years, we observed a sharp increase of Syphilis, especially among male who have sex with male (MSM), either HIV-infected, or on pre-exposure prophylaxis (PrEP). Our aim was to assess syphilis prevalence and incidence among people living with HIV (PLWH) and PrEP users. Methods PLWH were included from 2010 to 2020 and PrEP users from 2016 to 2020 from the Dat’AIDS French cohort. We calculated syphilis prevalence and incidences for first infections, re-infections, and iterative infections (> 2 times). T-Tests, Wilcoxon tests and Chi2 test were used for descriptive analysis and multivariate logistic regression models were used to estimate Odds ratios (OR) and 95% confidence intervals (95% CI) for factors associated with syphilis. Results Among the 8 583 PLWH, prevalence of subject with past or present syphilis was 19.9%. These subjects were more likely MSM or transgender and aged over 35 years, but prevalence was lower in AIDS subjects. Same pattern was seen for incident infection and re-infection. Incidence was 3.8 per 100 person-years for infection and 6.5 per 100 person-years for re-infection. Among 1 680 PrEP users, syphilis prevalence was 25.8%, with an estimated 7.2% frequency of active syphilis. Risk of syphilis infection was higher in male and increased with age. Incidence was 11.2 per 100 person-years for infection and 11.1 per 100 person-years for re-infection. Conclusion Syphilis prevalence and incidence were high, especially in older MSM with controlled HIV infection and PrEP users, enhancing the need to improve syphilis screening and behavioral risk reduction counseling among high-risk subjects.

Abstract
PURPOSE To investigate the ocular manifestation changes in human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) patents in a tertiary eye clinic in China over the past 18 years. METHODS In this retrospective cross-sectional study, 264 HIV/AIDS patients (528 eyes) were recruited at the Department of Ophthalmology, Peking Union Medical College Hospital, from 2001 to 2018. Patients underwent ophthalmic examinations, including best-corrected visual acuity (BCVA), slit-lamp microscopy, and indirect ophthalmoscopy, and completed a registration form including demographic characteristics, medical history, and immune status data. Kruskal-Wallis test or Mann-Whitney test was used to compare continuous variables, and Pearson's chi-squared test or Fisher's exact test was performed to compare categorical variables. RESULTS Regarding demographic characteristics, there was a significant increasing trend in male patients, sexual transmission, and HIV/AIDS-syphilis coinfection (all P < 0.001). For systemic features, more patients received cART, and fewer patients had systemic syndromes after 2003 (P < 0.001). For ocular manifestations, there were no significant changes between time intervals in CMVR and HIV retinopathy patients (P = 0.149, P = 0.643), but the proportion of patients with uveitis increased from 1.14% to 19.32% (P < 0.001). CONCLUSION CMVR was the most common ocular compilation in HIV/AIDS patients, followed by uveitis and HIV retinopathy. The proportion of patients with CMVR and HIV retinopathy was stable over time, but the proportion of patients with uveitis showed a significant increasing trend. Therefore, immediate ophthalmic examination should be performed at the point of care or as soon as possible after entry into the health care system.

Abstract
OBJECTIVE It has been reported that approximately 90% of patients who are infected with human immunodeficiency virus (HIV) have various cutaneous symptoms that are related to the virus. This study aims to describe the cutaneous disorders that have developed in HIV-infected patients and to investigate the factors that may be related, such as relationships to drug use and CD4 counts. METHODS This cross-sectional study included people who were living with HIV and being followed by our hospital's infectious diseases clinic after they had been referred to the dermatology clinic because of skin lesions. These patients had been diagnosed with HIV by enzyme-linked immunosorbent assay tests and were included in the study if they were older than 18 years and had agreed to participate. Findings from detailed dermatological examinations were recorded, along with the patients' CD4 counts, the durations of their illnesses, and the treatments they received. RESULTS 144 patients were included in the study. The most common mucocutaneous manifestation was seborrheic dermatitis, at 28.5% (n = 41). The mean CD4 count was 607.1 (min-max = 10.6-1982).The CD4 counts were divided into three groups in the study as follows: 22 (15.3%) patients with <200, 35 (24.3%) patients between 200 and 500, and 87 (60.4%) patients with >500. There were no statistical differences between these groups in terms of dermatological findings. Nevertheless, the highest rate of patients with three or more dermatological conditions was found among those with CD4 counts <200 (n = 11.50%). CONCLUSION Skin manifestations are common in patients who are HIV-positive; however, many skin disorders can be seen in HIV/acquired immunodeficiency syndrome (AIDS) patients whatever CD4 cell counts of these patients are.

Abstract
Syphilis, one of the earliest diseases to be discovered in humans, still remains an enigma when it comes to its myriad manifestations and changing epidemiological profiles. There has been a surge in cases in the last few decades due to various factors. The human immunodeficiency virus (HIV) epidemics, global travel, increased incidence of male to male sexually transmitted diseases, online relationships culminating in casual sex are few of the important factors. Increased awareness could also be a factor for increased diagnosis. The multitude of clinical features especially when it comes to secondary syphilis and the rare tertiary manifestations, which can mimic various systemic disorders still pose a diagnostic challenge to the best of venereologists and physicians. This review aims to discuss the causes of resurgence in syphilis and few recent developments in pathogenesis, which could have led to this resurgence.

Abstract
Although the HIV epidemic in Athens, Greece has reemerged and spread in men who have sex with men (MSM), state-supported PrEP programs have not been instituted. A PrEP intervention was implemented building upon an existing network cohort of MSM (308 participants; 1212 network members). A PrEP intervention cohort of 106 participants was selected based upon sex behaviors. Individual, partner, and network characteristics were compared between the cohorts. The PrEP cohort members were more highly connected and in more influential positions in the network than their peers. Further, their sexual network connections' behaviors increased their vulnerability to HIV infection relative to the rest of the network's sex partners. This included greater stimulant use (24.2% vs 7.0%; χ2 = 28.2; p < 0.001), greater rates of at least weekly condomless sex (OR = 2.7; 95% CI 2.1-3.5; χ2 = 59.2; p < 0.001) and at least weekly use of drugs or alcohol during sex (OR = 3.4; 95% CI 2.6-4.3; χ2 = 89.7; p < 0.001). Finally the PrEP cohort's social networks showed similarly increased vulnerability to seroconversion, including greater rates of injection drug use (4.1% vs 0.5%; χ2 = 3.9; p = 0.04), greater stimulant use (33.6% vs 14.6%; χ2 = 16.9, p < 0.001), and higher rates of recent STIs (21.6% vs 13.1%; χ2 = 4.4; p = 0.04). Thus, this PrEP intervention engaged individuals in vulnerable positions with vulnerable connections within an MSM community.

Abstract
BACKGROUND 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. METHODS 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. RESULTS 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]). CONCLUSIONS 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.

Effects of Case Management on Risky Sexual Behaviors and Syphilis Among HIV-Infected Men Who Have Sex With Men in China: A Randomized Controlled Study. Sex Transm Dis 2022; 49:22-28. [PMID: 34192724 PMCID: PMC8663520 DOI: 10.1097/olq.0000000000001502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Accepted: 06/07/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND The prevalence of syphilis is very high in human immunodeficiency virus (HIV)-positive men who have sex with men (MSM), and effective interventions are needed to educate HIV-positive individuals about behavioral and biological risk factors. Therefore, we developed a standard case management process and conducted a randomized controlled study to investigate the impact on risky sexual behaviors and syphilis in HIV-positive MSM. METHODS Men who have sex with men (n = 220) were enrolled and randomized to the case management intervention group and the control group between May 2016 and January 2017. The control group received routine HIV-related care. In addition to routine HIV-related care, those in the intervention group regularly received extended services from a well-trained case manager. Epidemiological information was collected during the baseline face-to-face interviews by a trained investigator. Serological tests for syphilis and assessments of risky sexual behaviors were performed at baseline and 6 and 12 months after the initiation of treatment. RESULTS The syphilis incidence rates in the intervention and control groups were 11.3 per 100 person-years and 20.6 per 100 person-years, respectively. The multivariable-adjusted hazard ratio (95% confidence inter) for syphilis in case management group was 0.34 (0.14-0.87). The percentages of participants who resumed risky sexual behaviors in both groups were significantly reduced (P < 0.05) but did not significantly differ between the 2 groups. CONCLUSIONS A case management intervention reduced the incidence of syphilis in HIV-positive MSM. We should further increase the content of case management on the basis of providing routine HIV-related care to those people.

Expressions of interferon-stimulated genes in peripheral blood mononuclear cells from patients with secondary syphilis. INFECTION GENETICS AND EVOLUTION 2021; 96:105137. [PMID: 34781038 DOI: 10.1016/j.meegid.2021.105137] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/06/2021] [Revised: 10/26/2021] [Accepted: 11/09/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Syphilis is a sexually transmitted disease that threatens human health worldwide. However, the immune regulation cascade caused by treponemia pallidum (TP) infection remains still largely unclear. METHODS To investigate the expression of ISGs in secondary syphilis (SS), we recruited 64 patients with SS and equal number of healthy participants to obtain their peripheral blood mononuclear cells (PBMCs). qRT-PCR was performed to estimate the expression of interferon-stimulated genes (ISGs) including CXCL10, OAS3, OAS1, MX1, IFIT3, IFIT2, IFI6 and AIM2. Receiver-operating characteristic (ROC) analysis was adapted to diagnostic value of these genes to distinguish healthy controls and patients with SS. RESULTS ISGs including CXCL10, OAS3, OAS1, MX1, IFIT3, IFIT2, IFI6 and AIM2 were all upregulated in PBMCs of patients with SS. Area under the ROC curve (AUC) of the 8 ISGs were all more than 0.5. IFIT3 exhibited the highest diagnostic value, followed by AIM2, IFIT2 and CXCL10, according to the Yoden Index. CONCLUSION ISGs including CXCL10, OAS3, OAS1, MX1, IFIT3, IFIT2, IFI6 and AIM2 were upregulated in patients with SS and they have diagnostic value for syphilis.

Abstract
Introduction Although syphilis is a frequent co-infection in patients with human immunodeficiency virus (HIV) infection, the influence of syphilis on immune response and virologic failure in HIV-infected patients following initiation of antiretroviral therapy (ART) is not well-defined. Methods A retrospective study was conducted at Tianjin Second People's Hospital to evaluate the prevalence of syphilis and immune status in 4171 ART-naïve patients. The study included patients who initiated ART between August 2009 and June 2019. Results The prevalence of syphilis was 40.1% in all ART-naïve patients and 42.5% in ART-naïve men who have sex with men. HIV/syphilis co-infection was associated with higher virologic failure (odds ratio (95% confidence interval): 1.30 (1.04, 1.63)). Patients with HIV/syphilis co-infection had lower median CD4+ T cell counts and CD4/CD8 ratios at baseline. After initiation of ART, patients co-infected with HIV/syphilis had smaller increases in CD4+ T cell counts and CD4/CD8 ratios than patients infected only with HIV. The rate of recurrence of syphilis or reinfection was 9% (n = 128) during seven years of ART. Conclusion HIV/syphilis co-infection had a negative impact on immune recovery and antiretroviral effectiveness. RPR titer and HIV viral load should be monitored in patients co-infected with HIV/syphilis, especially in patients with high RPR titers.

Abstract
BACKGROUND Syphilis represents a major public health concern disproportionately affecting HIV positive patients and in many cases both infections are newly diagnosed at the same time. To date, limited studies are available on syphilis incidence in patients with a new HIV diagnosis. METHODS Patients newly diagnosed with HIV in 2010-2018 were included in the study and screening tests for syphilis were performed at baseline and at least once a year. Primary aims were to analyse the incidence rate of HIV-syphilis co-infection and syphilis re-infection. Secondary objective was to identify characteristics independently associated with co-infection and re-infection. RESULTS Of 500 newly diagnosed HIV patients, 20% presented a concomitant positive syphilis serology. Among them, 54 patients had a serology indicative for an active syphilis requiring therapy, while 46 had a history of prior treatments. The independent factors for syphilis acquisition were: MSM contact (OR:2.64; 95%CI 1.48-4.72; p<0.001), male gender (OR:2.43; 95%CI 1.08-5.48; p=0.032), and age (OR:1.03; 95%CI 1.01-1.05; p=0.005 per year increasing). Presence of syphilis at the time of HIV diagnosis remained fairly stable during the study period (P for trend, p=0.689). We observed 52 syphilis re-infections related to 37 people. Patients with at least one re-infection were all males and 86.5% MSM. CONCLUSIONS Males and MSM with HIV presented high rates of syphilis co-infection and re-infection suggesting persistent high-risk sexual behaviours and the need for appropriate intervention strategies in order to early detect and treat syphilis avoiding life-threatening complications and the spread of the infection in the community.

Abstract
In Brazil, the increasing prevalence of HIV infection in young people makes it critical to know its distribution in university communities. In this cross-sectional study, we evaluated the impact of STI/HIV testing campaigns on university campuses from 2013 to 2017. The participants took part in rapid testing for HIV, syphilis, hepatitis B and C, and counseling sessions. A total of 2691 people participated in the campaigns. Of these, 79.4% were single, and 50.3% were women. The median age was 24 years old, and 77.9% of participants had ≥12 years of formal education. Most reported having unprotected sex in the last year (87.4%). The positivity rates for HIV, syphilis, hepatitis B virus, and hepatitis C virus were 0.56%, 1.20%, 0.19%, and 0.11%, respectively. The characteristics associated with HIV infection were being men who have sex with men (MSM) (aOR = 12.06; 95% CI = 3.83-37.99) and having <12 years of schooling (aOR = 3.28; 95% CI = 1.03-10.38). Factors associated with syphilis seropositivity were older age (aOR = 1.06; 95% CI = 1.03-1.09), multiple partners (aOR = 2.44; 95% CI = 1.08-5.50), and being MSM (aOR = 5.40; 95% CI = 2.49-11.72). Positivity for hepatitis B tended to decrease with the years of testing (p = 0.023) and for hepatitis C to increase with age (p = 0.035). Our study observed a high vulnerability to HIV and syphilis infection in a university community, which needs an early prevention strategy, including regular testing, continuing sexual education, easy access to condoms, and pre- and postexposure HIV prophylaxis.

Abstract
Background: Syphilis is a global health issue, which continues to occur at high rates worldwide, particularly in HIV-infected men, who have sex with men (MSM). Hepatitis can present as an uncommon manifestation of syphilis, and the diagnosis may be overlooked in favor of more common causes of liver injury in this group. Objectives: This study aimed to determine the prevalence and risk factors of syphilitic hepatitis among HIV-infected individuals diagnosed with acute syphilis. Methods: This cross-sectional study was conducted on HIV-infected individuals who regularly attended a tertiary clinic in Istanbul. The data were collected and analyzed between 2016 and 2019. Cases of syphilitic hepatitis were included according to the following criteria: (I) VDRL-confirmed Treponema pallidum infection after or simultaneously diagnosed with HIV infection; (II) elevated liver enzymes, including ALT, AST, and ALP, that resolved after penicillin treatment; and (III) exclusion of other causes of hepatitis. Sociodemographic characteristics of the participants, clinical and laboratory findings were evaluated using medical records. Results: Among 1,057 HIV-infected patients, 141 (13.3%) were diagnosed to have an early stage of syphilis, 138 of them were male. Nine (6.4 %) out of 141 patients had syphilitic hepatitis, and all of them were self-identified MSM. Moreover, 5 out of these 9 patients were simultaneously diagnosed with syphilis and HIV infection. Up to 10-fold increase in ALT/AST was noted in all of them, and a 3.5-fold increase in bilirubin was observed in two cases. The most prominent laboratory abnormalities in syphilitic hepatitis patients were the detection of a considerable increase in ALP and HIV RNA levels. Conclusions: Syphilitic hepatitis is not encountered rarely in HIV-infected individuals, predominantly MSM populations. Since HIV/syphilis coinfected patients are more infective as a result of higher HIV RNA levels, early diagnosis, and treatment are crucial.
