Effect of Early Syphilis Infection on Plasma Viral Load and CD4 Cell Count in Human Immunodeficiency Virus-Infected Men: Results From the FHDH-ANRS CO4 Cohort

BACKGROUND Concomitant syphilis and human immunodeficiency virus (HIV) infection is increasingly frequent in industrialized countries. METHODS From a large hospital cohort of HIV-infected patients followed up in the Paris area between 1998 and 2006, we examined the effect of early syphilis on plasma HIV-1 RNA levels and CD4 cell counts. We compared 282 HIV-1-infected men diagnosed as having incident primary or secondary syphilis with 1233 syphilis-free men matched for age (±5 years), sexual orientation, participating center, length of follow-up (±6 months), and immunologic and virologic status before the date of syphilis diagnosis (index date). Increase in viral load (VL) (plasma HIV-1 RNA) of at least 0.5 log or a rise to greater than 500 copies/mL in patients with previously controlled VL during the 6 months after the index date was analyzed, as were CD4 cell count variations and CD4 slope after the index date. RESULTS During the 6 months after the index date, VL increase was observed in 77 men with syphilis (27.3%) and in 205 syphilis-free men (16.6%) (adjusted odds ratio [aOR], 1.87; 95% CI, 1.40-2.49). Even in men with a VL of less than 500 copies/mL undergoing antiretroviral therapy, syphilis was associated with a higher risk of VL increase (aOR, 1.52; 95% CI, 1.02-2.26). The CD4 cell count decreased significantly (mean, -28/μL) compared with the syphilis-free group during the syphilis episode (P?=?.001) but returned to previous levels thereafter. CONCLUSIONS In HIV-infected men, syphilis was associated with a slight and transient decrease in the CD4 cell count and with an increase in VL, which implies that syphilis may increase the risk of HIV transmission, even in patients receiving antiretroviral therapy and with a VL of less than 500 copies/mL.     

Use of crystal methamphetamine among gay men in London

AIM: To examine the use of crystal methamphetamine (crystal meth) and its association with high-risk sexual behaviour among gay men in London. DESIGN: Cross-sectional surveys using self-administered questionnaires. SETTINGS: National Health Service (NHS) out-patient human immunodeficiency virus (HIV) treatment clinic in London; NHS HIV testing/sexual health clinics in London; central London gyms. PARTICIPANTS: HIV-positive gay men attending the HIV treatment clinic in 2002-03 (n = 388); HIV-negative gay men attending the HIV testing/sexual health clinics in 2002-03 (n = 266); gay men using the gyms between January and March 2003 (n = 445), 2004 (n = 653) and 2005 (n = 494). MEASUREMENTS: Percentage of gay men who reported: (i) using crystal meth in the previous 12 months; (ii) using other recreational drugs (e.g. cocaine, ecstasy, ketamine); (iii) high-risk sexual behaviour in the previous 3 months. FINDINGS: The percentage of gay men who had used crystal meth in the previous year varied by sample (HIV treatment clinic, 12.6%; HIV testing/sexual health clinics, 8.3%; gyms, 19.5%; P < 0.001) but did not change over time in the gyms (19.8%, 20.7%, 17.8%; P = 0.5). In all samples, the majority of men used crystal meth only once or twice a year. Most crystal meth users (> 80%) had taken other recreational drugs. Crystal meth and other drug users were more likely to report high-risk sexual behaviour than other men, e.g. HIV treatment clinic sample: crystal meth users, 34.7%; other drug users, 18.9%, non-users, 10.6%, P < 0.001. Cause and effect could not be established. CONCLUSION: Among gay men in London surveyed in clinics, approximately one in 10 reported using crystal meth in the previous 12 months (HIV-positive men 12.6%; HIV-negative men 8.3%). Most men used it infrequently--only once or twice a year. There was no evidence of increasing use of crystal meth between 2003 and 2005.     

Recent syphilis trends in Belgium and enhancement of STI surveillance systems

Over the past five years, a series of syphilis outbreaks mainly occurring among gay men have been observed in Europe. One of these outbreaks was reported in the city of Antwerp, Belgium, during the first quarter of 2001. This outbreak is still ongoing in 2004. Furthermore, active syphilis diagnoses reported by the Sentinel Laboratory Network rose by 89% in the country during the fourth quarter of 2003. An increase in Brussels was also observed during the same quarter (+300%; 24 cases reported). Overall, the sentinel network of clinicians reported that 93.4% of patients were male; among them, 79.9% were men having sex with men (MSM). The overall proportion of patients co-infected with HIV was 50.5% (MSM: 58.6%; male heterosexuals: 23.8%; females: 8.3%); 76.1% of co-infected patients were already aware of their HIV infection at the time they were diagnosed with syphilis.     

Use of anabolic steroids and associated health risks among gay men attending London gyms

Aim To examine, by HIV status, the use of anabolic steroids among London gay men and their effect on physical and mental health. Design Cross‐sectional survey using self‐administered questionnaire. Setting Six gyms in central London. Participants 772 gay men using the gyms in January–February 2000. Measurements Proportion of gay men who reported (i) using steroids, (ii) sharing injecting equipment, (iii) experiencing side‐effects and (iv) having suicidal thoughts or feeling depressed. Findings Of 772 gay men, 117 (15.2%) had used and 90 (11.7%) had injected steroids in the previous 12 months: HIV positive men (steroid use) 31.7% (40/126), HIV negative men 14.5% (69/477), never‐tested for HIV 4.7% (8/169) (p < 0.001). No one reported sharing needles or syringes. HIV positive men were more likely to have used steroids for medical reasons than other men (24.3% versus 5.9%, p = 0.01). Nearly all steroid users (96.4%) reported side effects including testicular atrophy (51.0%), insomnia (47.7%), depression between cycles (25.2%) and hypertension (19.0%). Steroid users were more likely to have had suicidal thoughts in the previous 6 months than non‐users (22.6% versus 11.2%, adjusted odds ratio after controlling for HIV status 1.84; 95% CI 1.10–3.12, p = 0.02) or to have felt depressed (49.1% versus 38.5%, adjusted OR 1.52, 95% CI 1.01–2.30, p = 0.047) Conclusion One in seven gay men surveyed in central London gyms in 2000 said they had used steroids in the previous 12 months. HIV positive men were more likely to have used steroids than other men, some therapeutically. Side effects were reported widely and steroid use was associated with having had suicidal thoughts and feeling depressed, although cause and effect could not be established. Our findings suggest that steroid use among gay men may have serious consequences for both physical and mental health.     

The introduction of HIV during 1979-80 in a sexually active homosexual population of Stockholm

Serological tests for hepatitis A (HA) and B (HB), syphilis and HIV were performed on blood samples from 3 groups of homosexual men: 220 and 124 asymptomatic men being investigated in 1978 and 1980 respectively and another 98 men suffering from HA during the winter 1979-80. The two asymptomatic groups revealed similar test results with respect to HA, HB and syphilis: about 25% had markers for HA, 50% for HB and 10-16% for syphilis. The 1979-80 HA group had a comparatively high frequency of markers for HB (64%) and for syphilis (34%), indicating that these men were sexually highly active. While all of the men in the 1978 test group were free from HIV antibodies, 2% of the 1980 and 6% of the 1979-80 group had antibodies to the virus. The results indicate that HIV was introduced to the gay population of Stockholm during 1979-80.     

Repeat HIV testing: high-risk behaviour or risk reduction strategy?

OBJECTIVE: To examine the characteristics of repeat and first-time HIV testers and consider their implications for HIV test counselling. METHODS: An anonymous questionnaire was completed by nearly 1500 people seeking an HIV test between September 1997 and July 1998 at a same-day HIV testing clinic in London, United Kingdom. Repeat testers were those people who had previously tested HIV negative and were returning for another test. Information was collected on self-reported unprotected penetrative sex (UPS) in the previous 3 months and reasons for seeking the present test. RESULTS: Overall, 50.6% (721/1446) of all clinic attenders were repeat testers: gay men 71.7% (337/470), heterosexual men 42.1% (208/494) and heterosexual women 38.6% (186/482). No significant differences were found between repeat and first time testers in the frequency of UPS (P > or = 0.06). However, gay men (but not heterosexual men and women) reporting three or more previous HIV tests were significantly more likely to report higher-risk UPS (i.e. with a partner whose HIV status was either positive or unknown) (42.2%) than those who had had one-two or no previous tests (25.3 and 25.4%, respectively; P = 0.002). Over half the heterosexual men and women, and one third of gay men said they were seeking the current HIV test in preparation for a new relationship; these proportions did not differ significantly between repeat and first-time testers (P > 0.1). CONCLUSION: In this London HIV testing clinic, no significant differences were found in the frequency of UPS between repeat and first-time testers with the exception of gay men with a history of three or more previous HIV tests, who reported elevated levels of high-risk sexual behaviour. For many people, repeat HIV testing has become part of a risk reduction strategy to establish seroconcordance with a regular partner. HIV test counselling provides the opportunity both to address high-risk behaviour and to reinforce personal risk-reduction strategies.     

The epidemiology of infectious syphilis in the Republic of Ireland

In response to the increasing numbers of syphilis cases reported among men having sex with men (MSM) in Dublin, an Outbreak Control Team (OCT) was set up in late 2000. The outbreak peaked in 2001 and had largely ceased by late 2003. An enhanced syphilis surveillance system was introduced to capture data from January 2000. Between January 2000 and December 2003, 547 cases of infectious syphilis were notified in Ireland (415 were MSM). Four per cent of cases were diagnosed with HIV and 15.4% of cases were diagnosed with at least one other STI (excluding HIV) within the previous 3 months. The mean number of contacts reported by male cases in the 3 months prior to diagnosis was 4 (range 0-8) for bisexual contacts and 6 for homosexual contacts (range 1-90). Thirty one per cent of MSM reported having had recent unprotected oral sex and 15.9% of MSM reported having had recent unprotected anal sex. Sixteen per cent of cases reported having had sex abroad in the three months prior to diagnosis. The results suggest that risky sexual behaviour contributed to the onward transmission of infection in Dublin. The outbreak in Dublin could be seen as part of a European-wide outbreak of syphilis. The rates of co-infection with HIV and syphilis in Ireland are comparable with rates reported from other centres. There is a need to improve surveillance systems in order to allow real time evaluation of interventions and ongoing monitoring of infection trends.     

Bisexual behavior and infection with HIV and syphilis among men who have sex with men along the east coast of China

This study examined the correlates of bisexual behavior and infection with HIV/syphilis among men who have sex with men only (MSM-only) and those who have sex with both men and women (MSMW) in Shandong, China. Cross-sectional surveys probed sociodemographic information, sexual and drug use behaviors, knowledge, and use of prevention services; blood samples were tested for HIV/syphilis status. Of 2996 participants, 39.5% acknowledged being MSMW; 60.5% being MSM-only; 2.5% were HIV-infected with similar rates for MSMW (2.5%) and MSM-only (2.6%); 5.5% syphilis-infected with comparable rates for MSMW (5.6%) and MSM-only (5.5%). In multivariable models, MSMW were more likely than MSM-only to be older, local residents, recruited from outdoor cruising area, drug users, and less likely to have used a condom during last anal sex with a male partner. HIV-infected MSMW were more likely to have syphilis and other sexually transmitted diseases (STDs) and less likely to have received peer education. HIV-infected MSM-only were more likely to be older, nonlocal residents, and have syphilis and other STDs. MSMW with syphilis were more likely to be recruited from Jinan, Qingdao, and Zibo (versus Yantai), infected with HIV, and less likely to have received lubricant promotion. MSM-only with syphilis were more likely to be recruited from Jinan and Qingdao (versus Yantai), drug users, infected with HIV, and have had sex with male partners in the past 6 months. High prevalence of bisexual behavior and HIV/other STDs with common unprotected sex and multiple sexual partners among Shandong's gay community revealed in this study highlighted the importance of bisexuals as a potential epidemiologic bridge. Further research is needed to investigate the impact of bisexual behaviors on population transmission.     

Syphilis outbreak in Walsall, UK: lessons for control and prevention

An assessment of risk-taking behaviour among men who have sex with men (MSM) attending a sauna venue was undertaken, using a standardized questionnaire, after which outreach screening was introduced targeting MSM. The epidemiology of the continuing outbreak of syphilis was reviewed to determine the factors driving the outbreak and assess the benefit of continuing outreach screening. Findings among the 163 respondents at the sauna included a high rate of casual sex and a tendency not to disclose HIV status. Over 12 months, 51 cases of early syphilis were recorded. Our review showed a decline in incidence in MSM after outreach screening, but an increase in heterosexual spread. Given the frequent anonymous nature of syphilis transmission, traditional contact tracing is ineffective. Outreach screening is required at gay venues and other community settings to target at-risk populations.     

Sexual risk behaviour among gay men in a relationship.

OBJECTIVE: To examine whether gay men in a relationship have adopted negotiated safety as an HIV risk reduction strategy. METHODS: A confidential, anonymous questionnaire was completed by 1004 gay men attending gyms in central London in September-October 1997. Information was sought on sociodemographic characteristics, HIV testing and sexual risk behaviour. Men reporting unprotected anal intercourse (UAI) in the previous 3 months were classified as 'status-unknown' if they did not know their own HIV status, that of their UAI partner(s) or both. Men who knew their own and their UAI partner's HIV status were classified as 'status-known'. RESULTS: Of the 1004 men surveyed, 986 provided complete information on relationship, personal HIV test history and HIV status of UAI partner. Over half (539) said they were currently in a relationship with another man, of whom 173 reported UAI in the previous 3 months; 140 (80.9%) with their main partner only, 18 (10.4%) with a casual partner only and 15 (8.7%) with both their main and casual partners. Of the 140 men reporting UAI only with their main partner, 62 (44.3%) did not know their own HIV status or that of their partner. Overall, a quarter (26.0%) of the men in a relationship reported UAI only with their main partner in the previous 3 months; 11.5% status-unknown UAI, 14.5% status-known UAI. In a multivariate logistic model, both age and being in a relationship were significantly associated with UAI (status-unknown and status-known). CONCLUSION: Gay men in a relationship, surveyed in central London gyms, have for the most part adopted the first principle of negotiated safety: only to have UAI with their main partner. However, not all have embraced the second principle: to establish HIV seroconcordance. Nearly half the men reporting UAI only with their main partner were unaware of their own HIV status, their partner's or both. As a consequence, more than one in 10 men in a relationship reported high-risk (i.e. status-unknown) UAI with their main partner. Because the study population, from central London gyms, was not randomly selected, these findings may not be generalizable to all gay men in London. Nonetheless, HIV prevention programmes should continue to encourage gay men in a relationship to seek an HIV test and establish seroconcordance if they wish to have UAI with each other.     

The people living with HIV stigma survey UK 2015: HIV-related sexual rejection and other experiences of stigma and discrimination among gay and heterosexual men

We aim to understand the difference in stigma and discrimination, in particular sexual rejection, experienced between gay and heterosexual men living with HIV in the UK. The People Living with HIV StigmaSurvey UK 2015 recruited a convenience sample of persons with HIV through over 120 cross sector community organisations and 46 HIV clinics to complete an online survey. 1162 men completed the survey, 969 (83%) gay men and 193 (17%) heterosexual men, 92% were on antiretroviral therapy. Compared to heterosexual men, gay men were significantly more likely to report worrying about workplace treatment in relation to their HIV (21% vs. 11%), worrying about HIV-related sexual rejection (42% vs 21%), avoiding sex because of their HIV status (37% vs. 23%), and experiencing HIV-related sexual rejection (27% vs. 9%) in the past 12 months. In a multivariate logistic regression controlling for other sociodemographic factors, being gay was a predictor of reporting HIV-related sexual rejection in the past 12 months (aOR 2.17, CI 1.16, 4.02). Both gay and heterosexual men living with HIV experienced stigma and discrimination in the past 12 months, and this was higher for gay men in terms of HIV-related sexual rejection. Due to the high proportion of men reporting sexual rejection, greater awareness and education of the low risk of transmission of HIV among people on effective treatment is needed to reduce stigma and sexual prejudice towards people living with HIV.     

An outbreak of syphilis in Oslo

During 1999 and 2000, an outbreak of syphilis occurred in Norway: 93 cases were reported to the National Institute of Public Health. This report summarizes a retrospective investigation of the medical records of 60 patients with primary, secondary and early latent syphilis treated during 1999-2000 at the Department of STD at the Ullev?l University Hospital in Oslo. Five women and 55 men were treated, mean age 38.6 and 44.9 years, respectively. Of the 60 cases, 14 (23.3%) had primary, 39 (65.0) secondary and seven (11.7%) early latent syphilis. Men who have sex with men (MSM) constituted 78.2% (43/55) of the male patients. Transmission among MSM was related to casual sexual contacts in bathhouses in Oslo. Two cases occurred among men with previously diagnosed HIV infection. Two new cases of HIV were reported. Condom use was inconsistent, and seldom used for oral sex.     

Being Unaware of Being HIV-Infected is Associated with Alcohol Use Disorders and High-Risk Sexual Behaviors Among Men Who have Sex with Men in Peru

This study compared the correlates of HIV risk among men who have sex with men (MSM) with newly diagnosed versus previously known HIV infection among 5,148 MSM recruited using modified snowball sampling in 5 Peruvian cities. Participants, if age ≥18 years and reporting sex with a male in the previous 12 months, underwent standardized computer-assisted risk assessments and HIV and syphilis testing. Overall, 420 (8.2 %) participants tested HIV seropositive, most of whom (89.8 %) were unaware of their HIV status. Compared to those who knew themselves to be HIV-infected, multivariate logistic regression demonstrated that unprotected anal intercourse at last encounter [AOR = 2.84 (95 % CI 1.09–7.40)] and having an alcohol use disorder (AUD) [AOR = 2.14 (95 % CI 1.01–5.54)] were independently associated with a newly diagnosed HIV infection. Being unaware of being HIV-infected was associated with high-risk sexual behaviors and AUDs, both of which are amenable to behavioral and medication-assisted therapy interventions.     

Gay Men Who Engage in Group Sex are at Increased Risk of HIV Infection and Onward Transmission

Among 746 participants in the Three or More Study (TOMS) of gay men who engaged in group sex in the previous 6 months, 22.4% reported unprotected anal intercourse (UAI) with any partners they did not know to be the same HIV serostatus as themselves. Not knowing oneself to be HIV-negative, not having a clear intention to use condoms, and more frequent group sex were independently associated with UAI. This study shows that gay men who engage in group sex represent an important priority for targeted HIV prevention activities and research.     

Sustained Reduction in Sexual Behavior that May Pose a Risk of HIV Transmission Following Diagnosis During Early HIV Infection Among Gay Men in Vancouver,British Columbia

Increased viral load during early HIV infection (EHI) disproportionately contributes to HIV transmission among gay men. We examined changes in sexual behavior that may pose a risk of HIV transmission (condomless anal sex (AS) with a serodiscordant or unknown status partner, CAS-SDU) in a cohort of 25 gay men newly diagnosed during EHI who provided information on 241 sexual partners at six time points following diagnosis. Twenty-two (88%) participants reported ≥1 AS partner (median time to first AS 80 days) and 12 (55%) reported ≥1 partnership involving CAS-SDU (median 116 days). In hierarchical generalized linear mixed effects models, AS was significantly less likely in all time periods following diagnosis and more likely with serodiscordant partners. The likelihood of CAS-SDU decreased three months after diagnosis and was higher in recently versus acutely infected participants. Most men in our study abstained from sex immediately after diagnosis with sustained longer-term reduction in CAS-SDU, confirming the importance of timely diagnosis during EHI.

目的了解汕头地区性病门诊患者梅毒及艾滋病感染情况。方法对皮肤性病防治院2004年1月至2011年12月性病门诊患者进行梅毒、艾滋病血清学检测,并对检测结果及临床资料进行统计分析。结果 14 491例性病门诊患者中,共确认梅毒阳性666例,阳性率4.60%。其中男性患者感染率为3.76%(384/10 214),女性患者感染率为6.59%(282/4 277),两者差异有统计学意义(P<0.01)。确认HIV阳性者20例,阳性率0.14%。其中男性患者HIV阳性率0.14%(14/10 214),女性患者阳性率0.14%(6/4 277),两者差异无统计学意义(P>0.05)。有6例HIV阳性者合并感染梅毒。结论汕头地区性病门诊就诊患者梅毒及HIV感染率近年虽未见明显增长,但还应继续做好性病高危人群HIV及梅毒的防治工作,争取早发现、早治疗,防范HIV及梅毒向一般人群的传播。     

Correlates of Unprotected Receptive Anal Intercourse Among Gay and Bisexual Men: Kampala, Uganda

We conducted a respondent-driven sampling survey (N = 215) to characterize correlates of risk for HIV infection among gay and bisexual men in Kampala, Uganda. We used RDSAT software to produce population estimates for measures and created exportable weights for multivariable analysis. Overall, 60.5% of gay/bi men identify as gay and 39.5% as bisexual; 91.6% are Ugandans. Unprotected receptive anal intercourse (URAI) was associated with identifying as gay, being younger and having had an HIV test in the past 6 months. Perceptions of being low risk to acquire or transmit HIV infection were paradoxically associated with higher likelihood of URAI. Programs to address risk of HIV infection among gay and bisexual men in Kampala need to address perceptions of risk among gay identified men.     

Recruiting London gay men into an HIV vaccine trial: is it feasible?

This paper describes a study among HIV-negative gay men in London to examine willingness to volunteer for an HIV vaccine trial. HIV-negative gay men (n=506) were surveyed in central London gyms in February-March 2002. Information was collected on willingness to volunteer for an HIV vaccine trial, attitudes toward HIV vaccines and sexual risk behaviour. Men reporting unprotected anal intercourse (UAI) in the previous three months with a man of unknown or discordant HIV status were classified as being at high risk of exposure to HIV (n=94, 18.6%). The remainder, who reported no UAI or UAI only with another HIV-negative man, were considered to be at low risk (n=412, 81.4%). Just under a quarter of the HIV-negative men in the study (23.4%) said they were either quite likely or very likely to volunteer for an HIV vaccine trial. High-risk men were more likely to say they would volunteer for a trial than low-risk men (37.2% versus 20.2%, p<0.001). Of the 506 HIV-negative men surveyed, eight (1.6%) were both high risk and very likely to volunteer for an HIV vaccine trial, while a further 27 (5.3%) were both high risk and quite likely to volunteer. Based on these figures, we estimated that to recruit 1,000 high-risk HIV-negative men into a vaccine trial between 15,000 and 62,000 HIV-negative men would need to be approached in the community. Compared with those at low risk, a greater proportion of high-risk men said that if they were in an HIV vaccine trial they would be more likely to have unprotected sex (23.4% versus 7.8%, p<0.001); that an effective vaccine will make safe sex less important (45.7% versus 31.3%, p=0.01); and that they would participate in an HIV vaccine trial even if they thought the vaccine might not work (46.8% versus 29.9%, p<0.01). This study suggests that, in London, to recruit high-risk HIV-negative gay men for an HIV vaccine trial many thousands of gay men may need to be approached in the community. Some HIV-negative men said that they would be more likely to have unprotected sex if they took part in a trial.     

CDC-funded HIV testing,HIV positivity,and linkage to HIV medical care in non-health care settings among young men who have sex with men (YMSM) in the United States

In the United States, HIV infection disproportionately affects young gay, bisexual, and other men who have sex with men, aged 13–24 years (collectively referred to as YMSM), specifically black YMSM. Knowledge of HIV status is the first step for timely and essential prevention and treatment services. Because YMSM are disproportionately affected by HIV, the number of CDC-funded HIV testing events, overall and newly diagnosed HIV positivity, and linkage to HIV medical care among YMSM in non-health care settings were examined from 61 health department jurisdictions. Differences by age and race/ethnicity were analyzed. Additionally, trends in number of HIV testing events and newly diagnosed HIV positivity were examined from 2011 to 2015. In 2015, 42,184 testing events were conducted among YMSM in non-health care settings; this represents only 6% of tests in non-health care settings. Overall and newly diagnosed HIV positivity was 2.8% and 2.1%, respectively, with black/African–American YMSM being disproportionately affected (5.6% for overall; 4% for newly diagnosed); 71% of YMSM were linked within 90 days. The newly diagnosed HIV positivity among YMSM decreased from 2.8% in 2011 to 2.4% in 2015, and the number of newly diagnosed YMSM also decreased. Further targeted testing efforts among YMSM are needed to identify undiagnosed YMSM, specifically black YMSM.
