Abstract
Background The epidemic of HIV infection among men who have sex with men (MSM) is a major public health concern in some parts of China, but data on trends in HIV incidence are limited. This study aimed to examine the trends in HIV incidence and factors associated with recent HIV infection among MSM in Jiangsu province, China, based on the limiting-antigen avidity enzyme immunoassay (LAg-Avidity-EIA) method. Methods Six consecutive surveys were implemented among MSM throughout Jiangsu province from 2016 to 2021. Participants were recruited in three ways. Socio-demographic and behavioral information were collected through face-to-face interviews. Venous blood samples were taken to test for HIV and syphilis. HIV incidence was estimated using the LAg-Avidity-EIA method. Chi-square trend tests were used to observe trends over the years. Multivariate regression analyses were used to identify factors associated with recent HIV infection. Results A total of 15,401 participants were enrolled in the study. The prevalence of HIV infection ranged from 8.0 to 9.8%, with no consistent rise or fall over the years (P = 0.189). HIV incidence ranged from 5.0 to 9.0%, and no uptrend or downtrend was shown (P = 0.418). MSM who lived locally for more than 2 years (aOR = 1.366, P = 0.019), had a lack of comprehensive HIV knowledge (aOR = 1.643, P = 0.031), had engaged in unprotected anal intercourse (UAI) in the past 6 months (aOR = 7.373, P < 0.001), had been tested for HIV within 12 months (aOR = 1.292, P = 0.035), and tested positive for syphilis (aOR = 2.840, P < 0.001) were likely to be recently infected with HIV. Conclusions HIV incidence among MSM has remained at a high level in Jiangsu province. In China, health education, condom use, and HIV/syphilis testing should continue to be top priorities for HIV prevention among MSM to reduce HIV transmission.

Abstract
Syphilis and HIV are important public health issues in the United States, especially in the southeastern region. This study aimed to determine and describe the co-infection pattern in Mississippi by using a case-controlled design to analyze cases diagnosed with syphilis or HIV from 2007 to 2016. Direct matching was employed to identify cases that were co-infected during the same calendar year, and binary logistic regression analysis was used to determine predictors of co-infection. Results showed that 1736 (34.0%) of syphilis and HIV cases were co-infected during the same calendar year. Binary logistic regression results demonstrated that race, gender, age group, and exposure category were independently associated with co-infection status. These analyses highlighted the progressive increase of co-infection rates in Mississippi. Collaboration between STI/HIV surveillance teams may identify high-risk individuals and reduce transmission of both diseases.

Abstract
For millions of years, microbiota residing within us, including those in the oral cavity, coexisted in a harmonious symbiotic fashion that provided a quintessential foundation for human health. It is now clear that disruption of such a healthy relationship leading to microbial dysbiosis causes a wide array of infections, ranging from localized, mild, superficial infections to deep, disseminated life-threatening diseases. With recent advances in research, diagnostics, and improved surveillance we are witnessing an array of emerging and re-emerging oral infections and orofacial manifestations of systemic infections. Orofacial infections may cause significant discomfort to the patients and unnecessary economic burden. Thus, the early recognition of such infections is paramount for holistic patient management, and oral clinicians have a critical role in recognizing, diagnosing, managing, and preventing either new or old orofacial infections. This paper aims to provide an update on current understanding of well-established and emerging viral, bacterial, and fungal infections manifesting in the human oral cavity.

Abstract
Background Since 2000, the incidence of syphilis has been increasing, especially among gay, bisexual, and other men who have sex with men (MSM) in the United States. We assessed temporal trends and associated risk factors for newly diagnosed syphilis infections among human immunodeficiency virus (HIV)-infected patients during a 16-year period. Methods We analyzed data from the HIV Outpatient Study (HOPS) cohort participants at 10 US HIV clinics during 1999-2015. New syphilis cases were defined based on laboratory parameters and clinical diagnoses. We performed Cox proportional hazards regression analyses of sociodemographic, clinical, and behavioral risk factors for new syphilis infections. Results We studied 6888 HIV-infected participants; 641 had 1 or more new syphilis diagnoses during a median follow-up of 5.2 years. Most participants were male (78%), aged 31-50 years, and 57% were MSM. The overall incidence was 1.8 (95% confidence interval [CI], 1.6-1.9) per 100 person-years (PY) and it increased from 0.4 (95% CI, .2-.8) to 2.2 (95% CI, 1.4-3.5) per 100 PY during 1999-2015. In multivariable analyses adjusting for calendar year, risk factors for syphilis included age 18-30 years (hazard ratio [HR], 1.3 [95% CI, 1.1-1.6]) vs 31-40 years, being MSM (HR, 3.1 [95% CI, 2.4-4.1]) vs heterosexual male, and being non-Hispanic black (HR, 1.6 [95% CI, 1.4-1.9]) vs non-Hispanic white. Conclusions The increases in the syphilis incidence rate through 2015 reflect ongoing sexual risk and highlight the need for enhanced prevention interventions among HIV-infected patients in care.

Abstract
OBJECTIVES The HIV epidemic is worsening among men who have sex with men (MSM) in China, especially among those who are younger than 25 years old [younger MSM (YMSM)]. The aim of the study was to compare the prevalences of HIV incidence and recent HIV infection as well as factors associated with recent HIV infection in YMSM and older MSM (OMSM). METHODS A multicentre cross-sectional survey was conducted among 4496 MSM recruited from seven Chinese cities. YMSM were defined as those aged < 25 years. Data on demographics and sexual behaviours were collected using structural questionnaires. Blood samples were tested for recent HIV infection and other sexually transmitted infections. RESULTS Among the participants, 1313 were YMSM and 3183 were OMSM. Compared with OMSM, YMSM had a higher prevalence of recent HIV infection [5.4% (71 of 1313) for YMSM vs. 3.6% (115 of 3175) for OMSM; P = 0.006] and a higher HIV incidence [11.8 per 100 person-years (PY) (95% confidence interval (CI) 9.0-14.5) for YMSM vs. 7.6 per 100 PY (95% CI 6.3-9.0) for OMSM]. The incidence increased with age among YMSM, especially between the ages of 16 and 21 years. In contrast, the incidence declined with age among OMSM. Anal bleeding, recreational drug use, syphilis and herpes simplex virus 2 (HSV-2) infection were independent risk factors for recent HIV infection among YMSM. The prevalence of all these risk factors increased with age between the ages of 16 and 21 years. Anal bleeding (19.8%) and recreational drug use (19.5%) had the highest adjusted population attributable fractions (aPAFs) among YMSM. The highest aPAFs of anal bleeding (27.4%) and syphilis infection (25.5%) were found between the ages of 19 and 21 years. CONCLUSIONS The HIV incidence in Chinese YMSM was significantly higher than that in OMSM. YMSM aged 16-21 years had an extremely high risk of recent HIV infection.

Abstract
OBJECTIVE We aim to analyze trend of syphilis and factors associated with recurrent episodes of syphilis among adults and adolescents attended in a STI/AIDS reference centers in Campinas, state of São Paulo, 2004 to 2012. METHODS Medical records, pharmacy data, and notification database were accessed to analyze trends of syphilis and sociodemographic, epidemiological and clinical variables associated with reinfection of syphilis. After univariate analysis, a hierarchical logistic regression model was adjusted to analyze variables associated with more than one episode of syphilis (dependent variable). First step (sex, age, and years of schooling) were tested and in the second, epidemiological and clinical variables. RESULTS A total of 1,009 episodes of syphilis were identified among 860 adolescents and adults, 117 individuals (13.6%) presented with more than one episode of syphilis. Factors associated with more than one episode of syphilis were sex (male) (OR = 4.28; 95%CI 1.31–14.0), age (OR = 1.02; 95%CI 1.00–1.04), homosexual/bisexual orientation (OR = 2.29; 95%CI 1.22–4.32), HIV coinfection (OR = 3.54; 95%CI 2.22–5.63), and absence of STI symptoms at the time of syphilis diagnostic (OR = 1.70; 95%CI 1.03–2.80). CONCLUSIONS The number of cases of syphilis and proportion in relation to STI increased in recent years in a specific population attended in a STI/AIDS reference centers in Campinas. Association with HIV, homosexual/bisexual orientation and the silent clinical characteristic of cases confirm the necessity to implement more aggressive strategies to prevent the occurrence of syphilis and other STI in specific populations with higher disease risk.

Abstract
INTRODUCTION Outbreaks of syphilis have been described among HIV-infected men who have sex with men (MSM) in Western communities, whereas reports in Asian countries are limited. We aimed to characterize the incidence and temporal trends of syphilis among HIV-infected MSM compared with HIV-infected non-MSM in Asian countries. METHODS Patients enrolled in the TREAT Asia HIV Observational Database cohort and with a negative non-treponemal test since enrolment were analyzed. Incidence of syphilis seroconversion, defined as a positive non-treponemal test after previously testing negative, was evaluated among patients at sites performing non-treponemal tests at least annually. Factors associated with syphilis seroconversion were investigated at sites doing non-treponemal testing in all new patients and subsequently testing routinely or when patients were suspected of having syphilis. RESULTS We included 1010 patients from five sites that performed non-treponemal tests in all new patients; those included had negative non-treponemal test results during enrolment and subsequent follow-ups. Among them, 657 patients were from three sites conducting regular non-treponemal testing. The incidence of syphilis seroconversion was 5.38/100 person-years (PY). Incidence was higher in MSM than non-MSM (7.64/100 PY vs. 2.44/100 PY, p<0.001). Among MSM, the incidence rate ratio (IRR) for every additional year from 2009 was 1.19 (p=0.051). MSM status (IRR 3.48, 95% confidence interval (CI) 1.88-6.47), past syphilis diagnosis (IRR 5.15, 95% CI 3.69-7.17) and younger age (IRR 0.84 for every additional 10 years, 95% CI 0.706-0.997) were significantly associated with syphilis seroconversion. CONCLUSIONS We observed a higher incidence of syphilis seroconversion among HIV-infected MSM and a trend to increasing annual incidence. Regular screening for syphilis and targeted interventions to limit transmission are needed in this population.

Abstract
INTRODUCTION Sexually transmitted diseases (STDs) are a major public health issue in Europe. Numerous outbreaks of syphilis have been described recently and an increased prevalence of high-risk sexual practices has raised concern about the transmission of HIV and other STDs. Similarly, an increase in sexually transmitted infections has been recorded in Northern Greece. METHODS This report describes a recent outbreak of syphilis in people living with HIV. The demographic, clinical, and serologic data of HIV patients diagnosed with syphilis were recorded and analyzed. Data on syphilis incidence from the general population was also compared to HIV patients' data. RESULTS Fifty-eight HIV-patients of the Infectious Diseases Unit of a tertiary hospital (5.2%) were diagnosed with syphilis during a three-year period (2008-2010). Highly active antiretroviral therapy (HAART) and coexistence of other STDs were independent predictors of syphilis (OR: 2.4, 95CI%: 1.26, 4.63, p=0.008; OR: 9.4, 95%CI: 4.49, 19.64, p<0.001, respectively). Origin from a country other than Greece (p=0.005), and homosexual contact (p=0.003), were separate risk factors for syphilis in the general population in the same area. CONCLUSION Diagnosis of a sexually transmitted disease in an HIV patient is a crucial clinical event that should trigger the clinician's suspicion for high-risk sexual behavior. Sexual health assessments should be a routine process for HIV patients.

Abstract
Epidemics of HIV among men who have sex with men (MSM) are major public health concerns in most parts of China. This study examined the trends in HIV incidence and associated factors among MSM in Jiangsu Province. Five consecutive cross-sectional surveys were conducted among MSM from 2011 to 2015 in eight cities throughout Jiangsu Province. Participants were recruited from MSM venues or via the internet. Demographic and behavioral data were collected through HIV bio-behavioral surveys. Blood specimens were collected to test for HIV and syphilis. HIV incidence was estimated by the IgG-capture BED-EIA (BED) method and a chi-square trend test was used to compare differences over the years. Multivariate logistic regression analysis was used to identify factors associated with recent infection. A total of 2433, 2678, 2591, 2610 and 2541 participants were enrolled in 2011, 2012, 2013, 2014 and 2015, respectively. HIV incidence increased from 5.10% in 2011 to 6.62% in 2015 (p = 0.025). MSM who had an education level of junior high school or less (aOR = 1.472, p = 0.018), engaged in condomless anal sex in the past 6 months (aOR = 2.389, p < 0.001), did not have an HIV test in the past 12 months (aOR = 3.215, p < 0.001), and were currently infected with syphilis (aOR = 2.025, p = 0.001) were likely to be recently infected with HIV. HIV incidence is increasing among MSM in Jiangsu Province, China. Condom usage and HIV testing promotion should be prioritized when attempting to reduce HIV transmission among MSM in China.

Abstract
BACKGROUND Voluntary medical male circumcision reduces the risk of HIV heterosexual transmission in men, but its effect on male-to-male sexual transmission is uncertain. METHODS Circumcision status of men who have sex with men (MSM) in China was evaluated by genital examination and self-report; anal sexual role was assessed by questionnaire interview. Serostatus for HIV and syphilis was confirmed. RESULTS Among 1155 participants (242 were seropositive and 913 with unknown HIV status at enrollment), the circumcision rate by self-report (10.4%) was higher than confirmed by genital examination (8.2%). Male circumcision (by examination) was associated with 47% lower odds of being HIV seropositive [adjusted odds ratio (aOR): 0.53; 95% confidence interval (CI): 0.27 to 1.02] after adjusting for demographic covariates, number of lifetime male sexual partners, and anal sex role. Among MSM who predominantly practiced insertive anal sex, circumcised men had 62% lower odds of HIV infection than those who were uncircumcised (aOR: 0.38; 95% CI: 0.09 to 1.64). Among those whose anal sex position was predominantly receptive or versatile, circumcised men have 46% lower odds of HIV infection than did men who were not circumcised (aOR: 0.54; 95% CI: 0.25 to 1.14). Compared to uncircumcised men reporting versatile or predominantly receptive anal sex positioning, those who were circumcised and reported practicing insertive sex had an 85% lower risk (aOR: 0.15; 95% CI: 0.04 to 0.65). Circumcision was not associated clearly with lower syphilis risk (aOR: 0.91; 95% CI: 0.51 to 1.61). CONCLUSIONS Circumcised MSM were less likely to have acquired HIV, most pronounced among men predominantly practicing insertive anal intercourse. A clinical trial is needed.

Abstract
Background: The national annually reported proportion of men who have sex with men (MSM) among people living with HIV (PLWH) is growing in China. To better inform the public health sector how to improve HIV prevention strategies, it is necessary to understand the current level of HIV incidence and its correlates. Methods: Google Scholar, PubMed, Web of Science and three major Chinese electronic publication databases (http://qikan.cqvip.com/, http://g.wanfangdata.com.cn/, http://www.cnki.net/, respectively) were searched for studies reporting HIV incidence. Comprehensive Meta-Analysis (CMA) 2.0 statistical software (Biostat, Inc. Englewood, NJ, USA) was used to calculate the pooled HIV incidence and perform subgroup-analysis to find correlates for HIV seroconversion in Chinese MSM. Random effects modelling was then conducted. Results: Twenty-five eligible studies were included in this meta-analysis. The calculated pooled HIV incidence was 5.61/100 person years (PY), with an increasing trend over time (3.24/100PY, 5.29/100PY, 5.50/100PY in 2005-2008, 2009-2011, 2012-2014 respectively, χ2 test for trend P = 0.04). Subgroup analyses indicated that age <25 years (rate ratio (RR) = 1.85), junior college education and below (RR = 1.87), having ≥ 2 male sexual partners in past 6 months (RR = 2.50), baseline syphilis infection (RR = 2.99), homosexual orientation (RR = 1.91), preferred bottom/versatile roles in anal sexual intercourse (RR = 2.33), and having unprotected anal intercourse in the past 6 months (RR = 2.16) significantly increased the risk for HIV seroconversion (each P < 0.05). Uncircumcised MSM had a marginal statistically significant higher HIV incidence (RR = 3.35, P = 0.051). Conclusion: HIV incidence is still alarmingly high among Chinese MSM. Stronger HIV intervention strategies should be implemented, in particular targeting young, less educated and syphilis-infected MSM.

Abstract
BACKGROUND Reverse sequence screening for syphilis, in which an automatable treponemal assay (enzyme immunoassay [EIA]/chemiluminescence assay [CIA]) is performed first and followed by a nontreponemal test for reactive specimens, has been used increasingly in the United States. The EIA is objective, efficient, and believed to be more sensitive than the rapid plasma reagin (RPR) because treponemal antibodies appear before nontreponemal antibodies. We sought to compare the sensitivity of a commonly used EIA, the Trep-Sure EIA (TS-EIA), to the RPR in cases of suspected primary syphilis infection in our clinic. METHODS A retrospective medical record review of patients with sexually transmitted infection clinic visits from January 2009 to December 2011 was conducted, and 52 patients met the following inclusion criteria: suspected primary syphilis symptoms, at least 1 positive syphilis test result at visit, and no history of syphilis. Sensitivity analyses compared the TS-EIA and RPR, using the reference standard of concordantly positive/reactive TS-EIA/RPR or positive fluorescent treponemal antibody absorption test (FTA-ABS) result. We considered equivocal TS-EIA results to be positive for sensitivity calculations because such results typically reflex to additional testing and therefore may still result in identifying new infections. RESULTS Twenty-eight (53.8%) of the 52 patients had a positive or equivocal TS-EIA. Twenty-five (89.3%) of those were RPR reactive; the remaining 3 (10.7%) were RPR nonreactive, FTA-ABS positive. Forty patients (76.9%) had a positive RPR, including 15 patients (37.5%) with negative TS-EIA results; all 15 were FTA-ABS positive. Nine additional patients were TS-EIA negative and RPR nonreactive but had a positive FTA-ABS result. The RPR was significantly more sensitive than the EIA (76.9% vs. 53.8%, P = 0.005). Trep-Sure EIA positivity was also significantly associated with higher median RPR titer (P = 0.011). CONCLUSIONS Use of the TS-EIA may result in underdetection of primary syphilis compared with the RPR. Further evaluation of the sensitivity of the TS-EIA in high-morbidity settings is warranted before the adoption of reverse sequence screening algorithms.

Abstract
BACKGROUND To better understand the factors associated with HIV- and sexually transmitted disease (STD)-transmitting behavior among HIV-infected persons, we estimated STD prevalence and incidence and associated risk factors among a diverse sample of HIV-infected patients in primary care. METHODS We analyzed data from 557 participants in the SUN Study, a prospective observational cohort of HIV-infected adults in primary care in 4 US cities. At enrollment and 6 months thereafter, participants completed an audio computer-assisted self-interview about their sexual behavior, and were screened for genitourinary, rectal, and pharyngeal Neisseria gonorrhoeae and Chlamydia trachomatis infections by nucleic acid amplification testing, and for serologic evidence of syphilis. Women provided cervicovaginal samples and men provided urine to screen for Trichomonas vaginalis by polymerase chain reaction. RESULTS Thirteen percent of participants had a prevalent STD at enrollment and 7% an incident STD 6 months later. The most commonly diagnosed infections were rectal chlamydia, oropharyngeal gonorrhea, and chlamydial urethritis among the men and trichomoniasis among the women. Other than trichomoniasis, 94% of incident STDs were identified in men who have sex with men. Polysubstance abuse other than marijuana, and having ≥4 sex partners in the 6 months before testing were associated with diagnosis of an incident STD. CONCLUSIONS STDs were commonly diagnosed among contemporary HIV-infected patients receiving routine outpatient care, particularly among sexually active men who have sex with men who used recreational drugs. These findings underscore the need for frequent STD screening, prevention counseling, and substance abuse treatment for HIV-infected persons in care.

Abstract
Objectives To assess HIV incidence and its associated risk factors among young men who have sex with men (YMSM) in urban areas, China. Design The study used a prospective cohort study design and standard diagnostic tests. Methods A twelve-month prospective cohort study was conducted among YMSM (18–25 years old) in 8 large cities in China. The participants were recruited via snowball sampling. A total of 1102 HIV-negative YMSM completed baseline assessment, 878 YMSM participants completed 6-month follow-up, and 902 completed 12-month follow-up. HIV was screened by an enzyme-linked immunosorbent assay and confirmed with Western Blot. Syphilis was screened via rapid plasma reagent and confirmed by treponema pallidum particle agglutination assay. Results 78 HIV seroconversions were identified within 1168.4 person-year observations yielding an incidence rate of 6.7 per 100 person-years. HIV seroconversion was associated with non-student status (RR = 2.61, 90% CI = 1.3–5.26), low HIV transmission knowledge (RR = 8.87, 90% CI = 2.16–36.43), and syphilis infection (RR = 5.04, 90% CI = 2.57–9.90). Conclusions Incidence of HIV among YMSM is high in urban areas of China. Interventions measures are required to contain the HIV epidemic within this population.

Abstract
OBJECTIVE Syphilis incidence has been steadily increasing among HIV-infected men in the United States, representing an important public health challenge to HIV prevention. Clinic-based HIV prevention interventions are available but may need to be revisited in response to syphilis epidemic. We wanted to better understand the current epidemiology of syphilis in rural HIV-infected men who routinely received HIV risk-reduction counseling in order to plan more effective HIV prevention strategies in clinical care. METHODS We conducted a retrospective cohort study to examine factors associated with syphilis infections in rural HIV-infected men who received sexually transmitted disease screening and HIV risk-reduction counseling during HIV primary care from January 2008 to June 2013. We assessed patients' demographic, clinical, behavioral and psychosocial characteristics and performed a multivariable exact logistic regression to identify factors related to syphilis. RESULTS Despite routine risk screening and HIV risk-reduction counseling, a total of 51 syphilis infections were diagnosed among 702 HIV-infected men (5 patients were diagnosed ≥ 2 episodes). The majority of the study participants was sexually active and reported at least one unsafe sexual behavior, mainly inconsistent condom use. Younger age (<35 years, adjusted odds ratio (aOR)=3.09), higher educational attainment (some college or above, aOR=3.72), and perception that the partner may have sex with other people (aOR=3.10) were significantly associated with syphilis infection. Non-injection drug use was related to syphilis in HIV-infected men who have sex with men (aOR=2.86). DISCUSSION Some HIV-infected men, especially young, educated men, or those who perceived that their partners may have sex with other people, continue to have high-risk behaviors that increase their own risks of acquiring syphilis and may also facilitate HIV transmission. New strategies need to be developed for HIV primary care providers to help HIV-infected patients maintain safer sex practices.

Abstract
OBJECTIVE To present a retrospective analysis of multicentre case series of oral syphilis and a review of relevant literature. SUBJECTS AND METHODS A PUBMED search was carried out from 1950 to 2011. Clinical records of patients with exclusive/prevalent oral manifestations of syphilis were collected and examined in three independent hospitals. RESULTS Of 23 reports describing 34 patients were detected through the review (35% primary, 56% secondary, and 9% tertiary disease), describing unspecific ulcers (59%), mucosal patches (23%), keratosis (6%), pseudomembranes (3%), and gumma (9%). Multicentre case series revealed 12 patients with oral syphilis, of which 17%, 58%, and 25% with, respectively, primary, secondary, and tertiary lesions. Clinically, patients showed white patches (17%), blistering mucositis (8%), chronic unspecific ulcers with/without skin lesions (50%), gumma (17%), and necrosis of the dorsum of the tongue (8%). Oral bullae and tongue necrosis are never described in the current review. CONCLUSIONS Diagnosis of syphilis remains a challenge because of the multiform and polymorphous clinical pattern at onset and its ability to imitate different diseases. It is mandatory to include syphilis in the differential diagnosis of unusual oral lesions. Diagnosis of oral lesions of syphilis is often difficult, and biopsy is required in controversial cases.

Abstract
To date, there are no studies from El Salvador among people with HIV to inform prevention programs. We conducted a study in El Salvador in 2008 among people with HIV using audio computer-assisted interviews on risk behaviors and access to health care. Blood was tested for syphilis and herpes simplex type 2 (HSV-2). Active syphilis was defined as RPR titer ≥1:8. Genital specimens were tested for other sexually transmitted infections (STI) by PCR. We evaluated factors associated with unprotected sex with last stable partner of HIV-negative or unknown status among those reporting a stable partner. A total of 811 HIV-positive individuals participated: 413 men and 398 women. Prevalence of Chlamydia and gonorrhea was low (≤1%), while prevalence of other STI was high: Mycoplasma genitalium (14%), syphilis (15% seropositivity, active syphilis 3%) and HSV-2 (85%). In multivariate analysis, disclosing HIV status to partner (OR 0.2, 95% CI: 0.1-0.3, p<0.001), participation in HIV support groups (OR 0.3, 95% CI: 0.1-0.8, p=0.01), easy access to condoms (OR 0.4, 95% CI: 0.2-0.9, p=0.04) were protective factors for unprotected sex. Reporting a casual partner in the last 12 months (OR 3.6, 95% CI: 1.5-8.5, p=0.004). and having an STI (OR 2.6, 95% CI:1.3-5.5, p=0.02) were associated with an increased odds of unprotected sex. Prevention interventions among HIV-positives in El Salvador should focus on increasing condom access, promoting HIV disclosure and couples testing and reducing the number of partners. The positive role of support groups should be used to enhance behavioral change.

Abstract
OBJECTIVE To investigate the relationship of lower urinary tract symptoms (LUTS) to urinary tract infection, prostatitis, sexually transmitted infection, lifetime sexual partner count, and recreational drug use in a population of men who have sex with men. LUTS in men are a source of considerable morbidity, distress, and medical expense. METHODS We conducted a cross-sectional, Internet-based survey of urinary quality-of-life outcomes in men who have sex with men. The main outcome was the International Prostate Symptom Score (IPSS), classified as none/mild (IPSS 0-7), moderate/severe (IPSS 8-35), or severe (IPSS 20-35). The participants were also asked whether they ever sought medical attention for urinary problems. RESULTS The survey web site was accessed by 2783 men, of whom 2348 (84.3%) completed the questionnaire. The median age was 39 years (range 18-81). Age, depression, human immunodeficiency virus infection, gonorrhea, syphilis, prostatitis, and prescription drug abuse were all associated with LUTS. Men who sought medical attention for LUTS were more likely to report older age, diabetes, depression, gonorrhea, urinary tract infection history, and prostatitis. CONCLUSION Specific infectious conditions of the urinary tract and depressive symptoms are independent predictors of LUTS in men who have sex with men. Although LUTS are often multifactorial, a common unifying explanation for our finding could be the effects of local and systemic inflammation on the lower urinary tract.

Abstract
A large-scale national survey was conducted in 2008 across 61 cities throughout China, covering over 18,000 men who have sex with men (MSM). The prevalence of human immunodeficiency virus (HIV) was 4.9% and incidence ranged from 2.6 to 5.4 per 100 person-years. The prevalence of sexually transmitted diseases ranged from 2.0% to 29.9% among MSM in different parts of China. Syphilis status, recruitment of sexual partners mainly from gay saunas, duration of MSM experience, and unprotected sex with regular male sex partners and multiple male sex partners predicted HIV seroconversion. The prevalence of consistent condom use was low during anal sex, ranging from 29.4% to 37.3%. Within this context, this paper considers the factors surrounding HIV prevention activity, and identifies a number of public health challenges which need to be considered if optimum outcomes are to be achieved. HIV prevention targeting MSM is a delayed response. The high risk associated with gay saunas and the need for steady condom supply at these venues needs urgent consideration. In addition, approximately one-third of MSM in China reported bisexual behavior, which may be attributed to sociocultural reasons and stigma against MSM. Female sex partners of MSM are seldom aware of their exposure to high risk of HIV transmission. Finally, the primitive nature of non-government organizations for HIV prevention and issues around their sustainability pose another serious challenge for the future of HIV prevention campaigns targeting MSM in China.

Abstract
A respondent-driven sampling survey was conducted to investigate HIV related serological and behavioral characteristics of men who have sex with men (MSM) in Guangzhou, China, and to identify associated factors potentially driving the epidemic. Respondent-Driven Sampling Analysis Tool and SPSS were used to generate adjusted estimates and to explore associated factors. Three hundred seventy-nine eligible participants were recruited. The adjusted prevalence of HIV and current syphilis infection are 5.2% and 17.5% respectively. 60.3% have unprotected anal sex in the past 6 months. Unprotected anal sex, having receptive anal sex and current syphilis infection are significant factors associated with HIV infection. The potential for a rapid rise of HIV and syphilis infections among MSM in Guangzhou exists. Targeted interventions with voluntary counseling and testing (VCT) and sexually transmitted infection (STI) services are needed to address the epidemic, with a focus on such subgroups as those of with current syphilis, and non-official Guangzhou residence status.

Abstract
OBJECTIVE A rebound of syphilis cases has recently been observed. This study describes the trend in syphilis infection among persons attending the AIDS information and prevention center of Valencia, Spain. METHODS We performed a cohort study of all persons attended from 2000 to 2006. The calendar effect was assessed by a logistic regression model adjusted by sexual and sociodemographic variables. RESULTS A total of 71% were heterosexuals (HT) and 19% were men who had sex with men (MSM). Among the 10,850 users of the center, the prevalence of syphilis was 0.7%. Among MSM, the prevalence of syphilis was 2.4% for the whole period and was 4.6% for 2006. Multivariate analysis showed that the risk of infection was lower in persons with a university education (OR=0.10; 95%CI: 0.03-0.59) than in those without. The risk was higher in persons who took drugs (OR=5.49; 95%CI: 1.55-19.43) or who practiced prostitution (OR=6.83; 95%CI: 2.52-18.53). In 2006, the risk of having syphilis was greater (OR=5.05; 95%CI: 1.12-22.72). CONCLUSIONS Syphilis infection increased substantially among MSM. In this collective, the prevalence of infection is related to educational level, prostitution and the use of non-injected recreational drugs.

Abstract
OBJECTIVES The emergence of non-AIDS-related events in the HIV-infected population experiencing a longer life expectancy implies the implementation of a comprehensive approach of HIV clinical management through better access to care, prevention, and early diagnosis of co-morbidities. METHODS The Orchestra program is a computer-assisted HIV care and support tool implemented since December 2004 in the outpatient clinic of a University Hospital set in Paris, France. The intervention aims at improving access to HIV information care and support specifically targeted five areas of actions: cardiovascular risk factors; gynecological follow-up; anti-hepatitis B virus (HBV) vaccine coverage; sexuality and prevention of sexually transmitted infections; and compliance to antiretrovirals. The impact of this program was examined prospectively on a "before-after" basis after a two-year implementation. RESULTS In the two-year period, 1717 patients were regularly followed. The level of the database information significantly increased in time (low density lipoprotein (LDL) cholesterol and glycemia were informed in 74% of patients at inclusion versus 95% at two years, and 83% versus 97%, p < 0.001, respectively). The number of targeted interventions was also higher. For eligible women, papanicolaou smears and mammography were prescribed in 52% of cases after intervention, versus 44% at inclusion, p0.04 and 83% versus 50%, p < 0.001, respectively. Indicators of care eventually improved significantly. Initially 72% non-adherent patients declared to be adherent after the intervention ( p < 0.001) and 67% of patients with initial LDL-hypercholesterolemia normalized their LDL level within two years ( p < 0.001). CONCLUSION The Orchestra program has provided a unique opportunity to assess and improve prevention and management of co-morbidities in HIV patients.

HIV and hepatitis B and C incidence rates in US correctional populations and high risk groups: a systematic review and meta-analysis. BMC Public Health 2010; 10:777.

Abstract
BACKGROUND High Human Immunodeficiency Virus (HIV) prevalence and high risk behaviors have been well documented within United States (US) correctional systems. However, uncertainty remains regarding the extent to which placing people in prison or jail increases their risk of HIV infection, and regarding which inmate populations experience an increased incidence of HIV. Describing these dynamics more clearly is essential to understanding how inmates and former detainees may be a source for further spread of HIV to the general US population. METHODS The authors conducted a systematic review and meta-analysis of studies describing HIV incidence in US correctional facility residents and, for comparison, in high risk groups for HIV infection, such as non-incarcerated intravenous drug users (IVDU) and men who have sex with men (MSM) in the US. HIV incidence rates were further compared with Hepatitis B and Hepatitis C Virus rates in these same populations. RESULTS Thirty-six predominantly prospective cohort studies were included. Across all infection outcomes, continuously incarcerated inmates and treatment recruited IVDU showed the lowest incidence, while MSM and street recruited IVDU showed the highest. HIV incidence was highest among inmates released and re-incarcerated. Possible sources of heterogeneity identified among HIV studies were risk population and race. CONCLUSIONS Although important literature gaps were found, current evidence suggests that policies and interventions for HIV prevention in correctional populations should prioritize curtailing risk of infection during the post-release period. Future research should evaluate HIV incidence rates in inmate populations, accounting for proportion of high risk sub-groups.

Epidemiological study of phylogenetic transmission clusters in a local HIV-1 epidemic reveals distinct differences between subtype B and non-B infections. BMC Infect Dis 2010; 10:262.

Abstract
Background The number of HIV-1 infected individuals in the Western world continues to rise. More in-depth understanding of regional HIV-1 epidemics is necessary for the optimal design and adequate use of future prevention strategies. The use of a combination of phylogenetic analysis of HIV sequences, with data on patients' demographics, infection route, clinical information and laboratory results, will allow a better characterization of individuals responsible for local transmission. Methods Baseline HIV-1 pol sequences, obtained through routine drug-resistance testing, from 506 patients, newly diagnosed between 2001 and 2009, were used to construct phylogenetic trees and identify transmission-clusters. Patients' demographics, laboratory and clinical data, were retrieved anonymously. Statistical analysis was performed to identify subtype-specific and transmission-cluster-specific characteristics. Results Multivariate analysis showed significant differences between the 59.7% of individuals with subtype B infection and the 40.3% non-B infected individuals, with regard to route of transmission, origin, infection with Chlamydia (p = 0.01) and infection with Hepatitis C virus (p = 0.017). More and larger transmission-clusters were identified among the subtype B infections (p < 0.001). Overall, in multivariate analysis, clustering was significantly associated with Caucasian origin, infection through homosexual contact and younger age (all p < 0.001). Bivariate analysis additionally showed a correlation between clustering and syphilis (p < 0.001), higher CD4 counts (p = 0.002), Chlamydia infection (p = 0.013) and primary HIV (p = 0.017). Conclusions Combination of phylogenetics with demographic information, laboratory and clinical data, revealed that HIV-1 subtype B infected Caucasian men-who-have-sex-with-men with high prevalence of sexually transmitted diseases, account for the majority of local HIV-transmissions. This finding elucidates observed epidemiological trends through molecular analysis, and justifies sustained focus in prevention on this high risk group.

Abstract
OBJECTIVE To examine the prevalence and correlates of HIV/syphilis infections and sexually transmitted diseases (STDs) among men who have sex with men (MSM) in Chongqing, China. METHOD Cross-sectional surveys were conducted to provide information, including sociodemographics, sexual and drug use behaviors, HIV knowledge, and HIV-related services in 2006 and 2007, respectively. Multiple methods, including venue-based recruitment, community outreach, Internet advertisements, and peer referral, were used to identify men in Chongqing willing to participate in this study. RESULTS Of the 1692 participants, 10.8% were HIV-infected (range by district: 7.0%-15.0%), 8.6% were syphilis-infected, and 15.3% self-reported STD-related symptoms. HIV infection was associated with older age, recruitment from bathhouses/saunas, less education, more male sex partners, sex with a woman in the past 6 months, syphilis infection, and STD-related symptoms. Syphilis infection was associated with older age, less education, inconsistent condom use with a man, STD-related symptoms, and HIV infection. STD-related symptoms were associated with older age, being of nonlocal residency, inconsistent condom use with a humans, having ever paid for sex with a humans, HIV infection, and being from District 1. CONCLUSIONS HIV and syphilis infections have reached alarmingly high rates in Chongqing's MSM population. Better targeted, in-depth and comprehensive intervention strategies are needed urgently, including education, condom promotion and distribution, STD control, drug use-related intervention, and advocacy for HIV counseling and testing with bridges to HIV prevention and care services. Widespread testing for HIV, syphilis, and other major STDs in this risk group should be considered as measures for control.

Abstract
Few behavioral interventions have been conducted to reduce high-risk sexual behavior among HIV-positive Men who have Sex with Men (HIV+ MSM). Hence, we lack well-proven interventions for this population. Positive Connections is a randomized controlled trial (n = 675 HIV+ MSM) comparing the effects of two sexual health seminars--for HIV+ MSM and all MSM--with a contrast prevention video arm. Baseline, 6-, 12- and 18-month follow-up surveys assessed psychosexual variables and frequency of serodiscordant unprotected anal intercourse (SDUAI). At post-test, intentions to avoid transmission were significantly higher in the sexual health arms. However, SDUAI frequency decreased equally across arms. HIV+ MSM engaging in SDUAI at baseline were more likely to leave the study. Tailoring interventions to HIV+ MSM did not increase their effectiveness in this study. A sexual health approach appeared as effective as an untailored video-based HIV prevention intervention in reducing SDUAI among HIV+ MSM.

Abstract
OBJECTIVES To assess the prevalence of sexually transmitted infections (STI) and relationships between them and sociodemographic/behavioural data in the major Venereology Clinic in Lisbon. METHODS Every patient attending this STI clinic for the first time in the first 17 weeks of 2007 was enrolled in this study. Early syphilis, Chlamydia trachomatis infection, gonorrhoea, human immunodeficiency virus (HIV) first diagnosed and genital warts were considered for the study of statistical associations with sociodemographic/behavioural variables or other STI. Data were analysed with an exact significance level of 5%. RESULTS A total of 743 patients were included. In women (n = 296), the only significant associations found were for C. trachomatis and being non-Caucasian (OR = 2.13, CI 1.17-3.9) or being younger than 25 years (OR = 1.9, CI 1.31-2.79). Men who have sex with men (176 of the 447 male patients) contributed to 39% of the STI, although more than half of the early syphilis, gonorrhoea and HIV cases were diagnosed in this group. CONCLUSIONS Despite its limitations, our study allows some insight into the relationships between sociodemographic factors and STI in a selected population attending Lisbon's major Venereology Clinic. The results were similar to those of other European studies and to recent trends in STI, but differ in the association between C. trachomatis infection and non-Caucasian women, which is similar to cities with significant African minorities. Attention should be given to the associations found between men who have sex with men and STI such as gonorrhoea, syphilis and HIV, as these associations can lead to serious difficulties in the control of HIV infection in Portugal.

Abstract
"Stop the Sores" (STS), a humor-based syphilis prevention campaign, was implemented in response to increasing syphilis prevalence among gay and bisexual men in Los Angeles County. In 2004, 564 men completed surveys measuring exposure and reactions to the campaign and syphilis testing. Mean age was 39, and men of color comprised a significant proportion of the sample (46.8%). Most men reported being HIV-negative (79.3%). Overall, 7.8% of the sample reported ever having syphilis; HIV-positive men were six times more likely to report this. Over one half of the sample (58.5%) reported exposure to the campaign. Men reporting any recent unprotected anal sex were twice more likely (than those who did not) to see the campaign. Men of color were twice more likely than White men to report wanting to speak to their friends about it. Finally, 39.1% of men exposed to the campaign reported being tested for syphilis as a result. Factors related to higher likelihood to test for syphilis included HIV seropositive status, any recent unprotected anal insertive sex, recent use of methamphetamine, recent use of "poppers," and recent use of erectile dysfunction drugs. Although STS was somewhat effective, outreach efforts to particular subgroups may need to increase.

Abstract
Many HIV-positive persons reportedly continue to engage in at-risk behavior. We compared the sexual and drug-using practices of HIV-positive persons before and after the diagnosis of HIV infection to determine whether their behavior had changed. To this end, in 2006, we conducted a cross-sectional study involving clinical centers in five Italian cities. Each center was asked to enroll 100 persons aged 18 years or older who had a diagnosis of HIV infection that dated back at least 2 years. Data were collected with a specifically designed questionnaire, administered during a structured interview. The McNemar chi2 test was used to compare the data before and after the diagnosis. A total of 497 persons participated (65.5% males; median age of 40 years; age range, 34-45 years). The most common exposure categories were: heterosexual contact (43.4%), homosexual contact (27.2%), and injecting drug use (20.6%). Although the percentage of drug users significantly decreased after diagnosis, 32.4% of injectors continued to use drugs, and approximately half of them exchanged syringes. Regarding sexual behavior, after diagnosis there was a significant decrease in the number of sexual partners and in stable relationships and an increase in condom use, both for persons with stable partners and those with occasional partners, although the percentage varied according to the specific sexual practice. These results indicate that though at-risk behavior seems to decrease after the diagnosis of HIV infection, seropositive persons continue to engage in at-risk practices, indicating the need for interventions specifically geared toward HIV-positive persons.

Abstract
BACKGROUND Successful conduct of HIV vaccine efficacy trials entails identification and enrollment of at-risk populations, assessment of appropriate end points as measures of vaccine efficacy for prevention of HIV acquisition, and amelioration of disease course among infected vaccinees, as well as identification of potential confounders or effect modifiers. Although not invariably useful and bringing their own cost in terms of measurement and validation, a variety of biomarkers may aid at each stage of trial conduct. METHODS A review of selected articles, chosen based on quality, relevance of the biomarker to HIV vaccine trials, and availability of the publication, was conducted. The authors also drew experience from current trials and other planned or ongoing trials. CONCLUSIONS Biomarkers are available to assess HIV incidence in potential study populations, but care is needed in interpreting results of these assays. During trial conduct, sexually transmitted infections such as herpes simplex virus type 2 may act as effect modifiers on primary and secondary end points, including HIV incidence and set point viral load. The utility of sexually transmitted infection biomarkers will likely depend heavily on local epidemiology at clinical trial sites. Analyses from recent large HIV vaccine efficacy trials point to the complexities in interpreting trial results and underscore the potential utility of biomarkers in evaluating confounding and effect modification.

Abstract
Syphilis is caused by Treponema pallidum an anaerobic filamentous spirochete. In recent years, striking outbreaks have occurred in USA, Canada, Russia, China and some areas of Central and Eastern Europe. Main epidemiology changes reflect sex industry, sexual promiscuity, decreasing use of barrier protection (i.e. condoms) due to false sense of security that nowadays sexually transmitted diseases are curable and lack of pertinent knowledge. Considering that the initial presentation of syphilis may be the oral cavity, it is of great relevance to include this disease in the differential diagnosis of unusual oral ulcerations and white patches. Primary syphilis is a highly infectious disease in which inappropriate treatment may be apparently curative while the patient remains highly infectious. It is then of pivotal importance that clinicians maintain a high clinical index of suspicion. At the present time, clinical-pathologic correlation together with serologic studies remain essential in establishing the diagnosis of syphilis.

Abstract
Given the increasing emphasis on "prevention with positives" programs designed to promote HIV transmission risk reduction among people living with HIV/AIDS, better understanding of influences upon serostatus disclosure in sexual situations is needed. Based on grounded theory analyses of individual interviews, this exploratory research hypothesizes and interprets how 15 HIV-positive men who have sex with men (MSM) formed personal HIV disclosure policies for sexual situations. Participants described five elements influencing development of their personal policies, including: (1) making sense of having been infected, (2) envisioning sex as an HIV-positive man, (3) sorting through feelings of responsibility for others, (4) responding to views of friends and the gay community, and (5) anticipating reactions and consequences of disclosure. The article concludes with implications for current initiatives for prevention with positives.

Abstract
BACKGROUND Genital ulcer disease (GUD), including syphilis, is an important cause of morbidity in low and middle income (LMI) countries and syphilis transmission is associated with HIV transmission. METHODS We conducted a literature review to evaluate syphilis infection among drug users in LMI countries for the period 1995-2007. Countries were categorized using the World Bank Atlas method [The World Bank. (2007). Data and statistics: Country groups. Retrieved online October 18, 2007 at http://go.worldbank.org/D7SN0B8YU0] according to 2006 gross national income per capita. RESULTS Thirty-two studies were included (N=13,848 subjects), mostly from Southeast Asia with some from Latin America, Eastern Europe, Central and East Asia, North Africa and the Middle East but none from regions such as Sub-Saharan Africa. The median prevalence of overall lifetime syphilis (N=32 studies) was 11.1% (interquartile range: 6.3-15.3%) and of HIV (N=31 studies) was 1.1% (interquartile range: 0.22-5.50%). There was a modest relation (r=0.27) between HIV and syphilis prevalence. Median syphilis prevalence by gender was 4.0% (interquartile range: 3.4-6.6%) among males (N=11 studies) and 19.9% (interquartile range: 11.4-36.0%) among females (N=6 studies). There was a strong relation (r=0.68) between syphilis prevalence and female gender that may be related to female sex work. CONCLUSION Drug users in LMI countries have a high prevalence of syphilis but data are limited and, in some regions, entirely lacking. Further data are needed, including studies targeting the risks of women. Interventions to promote safer sex, testing, counselling and education, as well as health care worker awareness, should be integrated in harm reduction programs and health care settings to prevent new syphilis infections and reduce HIV transmission among drug users and their partners in LMI countries.

Abstract
We examined changes and correlates of sexual risk behavior of men who have sex with men (MSM) compared with heterosexual men and women over three time periods. Data from the 1997, 1999, and 2003 Los Angeles County Health Surveys, a population-based telephone survey, were analyzed to examine the association of sociodemographic and health-related factors with sexual risk behaviors among the three groups. In each time period, MSM reported a significantly greater percentage of sexual risk (i.e., both inconsistent condom use and multiple sex partners in the past 12 months) compared with heterosexual men and women. Multivariate analyses indicated that MSM and heterosexual men reported greater sexual risk than heterosexual women. Respondents who were younger, U.S. born, reported heavy alcohol consumption, or had been tested for HIV in the past 24 months were more likely to report sexual risk behavior. The findings suggest the need for continued targeted prevention for MSM and prevention efforts for segments of the general population at elevated risk for HIV.

Abstract
OBJECTIVES To evaluate the incidence of early syphilis based on time from initiation of highly active antiretroviral therapy (HAART) in human immunodeficiency virus (HIV)-infected patients. STUDY DESIGN Five hundred thirty-nine HIV-positive patients undergoing HAART were followed up to 4 years to identify early (primary or secondary) syphilis. Incidence rate trends according to time from HAART initiation were evaluated by Poisson regression after adjustment for calendar year. RESULTS With median follow-up of 2.9 years, 56 (10.4%) patients experienced early syphilis, 17 (3.2%) with primary syphilis, and 39 (7.2%) with secondary syphilis. The overall incidence rate of early syphilis for 4 years after the start of HAART was 4.57 per 100 person-years (95% confidence interval, 3.45-5.93). The incidence rate of early syphilis significantly increased in proportion to the years after the start of HAART (3.4-6.1 per 100 person-year, P for trend <0.001). CONCLUSIONS Early syphilis incidence in HIV-infected patients increased in proportion to HAART duration. The finding suggests that screening for syphilis in HIV-infected patients who initiate HAART should be encouraged with attention to the time passed since HAART initiation.

Chesson HW, Collins D, Koski K. Formulas for estimating the costs averted by sexually transmitted infection (STI) prevention programs in the United States. COST EFFECTIVENESS AND RESOURCE ALLOCATION 2008; 6:10. [PMID: 18500996 PMCID: PMC2426671 DOI: 10.1186/1478-7547-6-10] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2007] [Accepted: 05/23/2008] [Indexed: 01/30/2023] Open
Abstract
Background Sexually transmitted infection (STI) prevention programs can mitigate the health and economic burden of STIs. A tool to estimate the economic benefits of STI programs could prove useful to STI program personnel. Methods We developed formulas that can be applied to estimate the direct medical costs and indirect costs (lost productivity) averted by STI programs in the United States. Costs and probabilities for these formulas were based primarily on published studies. Results We present a series of formulas that can be used to estimate the economic benefits of STI prevention (in 2006 US dollars), using data routinely collected by STI programs. For example, the averted sequelae costs associated with treating women for chlamydia is given as (Cw)(0.16)(0.925)(0.70)($1,995), where Cw is the number of infected women treated for chlamydia, 0.16 is the absolute reduction in the probability of pelvic inflammatory disease (PID) as a result of treatment, 0.925 is an adjustment factor to prevent double-counting of PID averted in women with both chlamydia and gonorrhea, 0.70 is an adjustment factor to account for the possibility of re-infection, and $1,995 is the average cost per case of PID, based on published sources. Conclusion The formulas developed in this study can be a useful tool for STI program personnel to generate evidence-based estimates of the economic impact of their program and can facilitate the assessment of the cost-effectiveness of their activities.

Abstract
OBJECTIVE To estimate human immunodeficiency virus (HIV) incidence and associated risk factors among men who have sex with men (MSM) participating in the Omega Cohort Study in Montreal, 1996-2003. METHODS Longitudinal study of 1587 MSM seronegative at baseline with > or =1 six-month follow-up visit. Multivariate Cox regression with time-dependent variables was used for data analysis. RESULTS HIV incidence was 0.62 per 100 person-years (95% confidence interval: 0.41-0.84). In multivariate analyses compared with subjects not reporting any anal sex with serodiscordant or casual partners, those reporting anal sex with such partners (all P values <0.05), whether consistently protected [hazard ratio (HR) = 3.4], or unprotected exclusively receptive (HR = 12.0), exclusively insertive (HR = 4.7), or both receptive and insertive (HR = 8.3), were at increased risk of seroconversion. Sexual behaviors with seroconcordant regular partners were not associated with seroconversion. CONCLUSION These results observed in a cohort of MSM with low HIV incidence provide new insights regarding the debate about harm-reduction strategies to prevent sexual HIV transmission.

Abstract
In light of the abruptness and severity of the HIV/AIDS epidemic in Asia, there has been growing concern in recent years about the HIV/AIDS risks with the steady rate of Asian and Pacific Islander (AAPI) migration to the United States. Little is known, however, about existing HIV risks among non-MSM (men who have sex with men) AAPIs. The purpose of this study was to examine self-reported HIV testing behaviors and their correlates among a sample of 604 Southeast Asians living in a U.S. urban setting. The HIV testing rate among our sample adults is 30.8%, lower than the median HIV testing rate in the U.S. adult population by state, lower than that of the general adult testing rate in the study city, and lower than that of the AAPI MSM population. A low sexually transmitted infection (STI) testing rate as a proxy for low perceived sexual risks and a dearth of HIV knowledge were associated with the low HIV testing rate. Traditional health care access measures, such as availability of medical insurance and a personal doctor, cannot explain the low HIV testing rate in this predominantly immigrant population. Culturally and linguistically appropriate HIV prevention campaigns could increase the awareness of HIV/STI risk in this AAPI population.

Abstract
OBJECTIVE To review the epidemiology, clinical features, diagnosis, and treatment of syphilis. DATA SOURCES Studies and reviews were abstracted from MEDLINE (1950-April 2007) using the search term syphilis. All papers were cross-referenced to identify additional studies and reviews for inclusion. STUDY SELECTION AND DATA EXTRACTION Pertinent original research articles, review articles, and book chapters were evaluated. DATA SYNTHESIS Syphilis is a spirochetal disease that has plagued mankind for centuries. Following a low incidence of syphilis in the US for the last 2 decades, rates are now increasing both in the US and other parts of the world. Once acquired, syphilis can pass through 4 distinct stages of disease: primary syphilis, secondary syphilis, latent syphilis, and tertiary syphilis, with each stage being characterized by different symptoms and levels of infectivity. Diagnosis is made primarily by serologic assays with nontreponemal tests such as the Venereal Disease Research Laboratory and the Rapid Plasma Reagin assay used for screening. Treponemal tests including the Treponema pallidum particle agglutination and the fluorescent treponemal antibody absorption test are then used for confirmation. Recommended treatment regimens are based largely on uncontrolled trials and clinical experience. Penicillin is the treatment of choice, with the preparation and treatment duration varying for different stages. Benzathine penicillin is the treatment of choice for all stages of syphilis except neurosyphilis, for which aqueous crystalline penicillin or procaine penicillin is used due to the central nervous system penetration of these formulations. Coinfection with both syphilis and HIV occurs frequently due to common risk factors. These 2 diseases interact with each other, making both diagnosis and treatment more complicated. CONCLUSIONS Clinicians should be aware of the signs and symptoms of syphilis as well as current guidelines for the management and treatment of this disease.

Abstract
BACKGROUND Since 1996, there has been a resurgence in sexually transmitted infections (STIs) among men who have sex with men (MSM) in Western Europe. This has coincided with a significant decrease in HIV-associated mortality following the introduction of highly active antiretroviral therapies (HAART) and a corresponding increase in the number of MSM living with HIV. Levels of unprotected anal intercourse have also increased. In this article, we use STI surveillance data from a number of Western European countries to better understand the contribution of HIV-positive MSM to the recent increase in STIs. METHODS Published literature, surveillance reports, and ad hoc publications relating to HIV prevalence trends and STIs among HIV-positive MSM in Western Europe were reviewed. RESULTS Post-HAART, HIV prevalence among community samples of MSM ranged from 5% to 18%. HIV prevalence among MSM diagnosed with an STI was substantially higher. On average, HIV prevalence among MSM diagnosed with syphilis in 11 countries was 42% (range 14%-59%). Most HIV-positive MSM with syphilis were aware of their HIV status. In England and Wales, 32% of MSM with gonorrhea were HIV-positive in 2004. Outbreaks of lymphogranuloma venereum have been documented in 9 countries; HIV-positive MSM accounted for 75% of cases on average (range 0%-92%). Cases of sexually transmitted hepatitis C have been predominantly identified among HIV-positive MSM in Rotterdam, Paris, Amsterdam, and the United Kingdom. CONCLUSIONS In Western Europe, STIs have been disproportionately diagnosed among HIV-positive MSM post-HAART. Improved survival coupled with serosorting among HIV-positive MSM appears to explain the high prevalence of HIV among MSM with STIs. STI transmission among HIV-positive men will have contributed substantially to increasing STI trends seen among MSM in Western Europe, since 1996. These findings highlight the need for routine STI testing among HIV-positive MSM as well as safer sex messages highlighting the implications of STI coinfection.

Abstract
The epidemic use of methamphetamine in the United States is a growing public health problem. Recently its use has increased among gay men who live in urban areas, with accompanying increases in sexually transmitted diseases. This study examined how methamphetamine and sexual health are framed. It investigated the stigma associated with heterosexuals and gay men. Stories from 13 urban newspapers in cities with large populations of gay men published from 2000 to 2006 were analyzed. Results indicated that methamphetamine and sexual health were framed primarily as an individual, present problem. Stories framed methamphetamine as a health problem slightly more often than as a crime problem, but health was the dominant frame in stories mentioning gay men. Crime was the dominant frame in stories with heterosexuals. Articles tied gay men to sexual health issues. Findings indicate gay men and heterosexuals are stigmatized in news coverage of sexual issues and methamphetamine but in different ways.
