Sexually Transmitted Diseases in Men Who Have Sex with Men: A Clinical Review

Syphilis on the rise: A prolonged syphilis outbreak among HIV-infected patients in Northern Greece

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.

HIV and sexually transmitted diseases

While STDs have an important impact on HIV transmission, experimental intervention studies demonstrating that STD control reduces HIV incidence have had mixed results. STDs can impact the clinical management of patients infected with HIV by increasing both viral load and HIV infectiousness. The clinical management of STDs is a dynamic field that has seen the advent of new diagnostic assays as well as changes in susceptibility to and availability of antimicrobial agents. As a result, excellence in HIV medical care requires physicians to be current in STD medicine. Physicians who care for patients with HIV infection should be familiar with recent guidelines recommending routine risk assessment and STD screening in these patients.

A meta-analysis of the effect of new-media interventions on sexual-health behaviours

BACKGROUND AND OBJECTIVES

Direct access to individuals in non-intrusive ways, as well as the technical abilities of new-media to provide tailored information in relatively inexpensive ways, creates a unique opportunity for the delivery of health-related information. The aim of the present research was to examine the effect that new-media-based sexual-health interventions have on sexual-health behaviours in non-clinical populations and to determine the factors that moderate the effect of technology-based sexual-health interventions on sexual--health behaviours.

DATA SOURCES

A systematic literature search of the following databases was conducted: MEDLINE, psycINFO, Global health, and EMBASE, using terms that captured three subject areas-'Sexual-health', 'New Technology' and 'Intervention'.

STUDY ELIGIBILITY CRITERIA

Randomised controlled trial, or a quasi-experiment; delivered exclusively via new-media; included sexual risk behaviour change as an outcome measure and delivered to non-clinical groups.

RESULTS

Twelve studies tested the effect of new-media interventions on condom use, whereas nine tested the effect on sexually transmitted disease testing. Results indicated that new-media interventions led to significant increases in both outcomes; however, these effects were not homogeneous. Moderation analyses revealed that interactivity of the intervention, target population and study design influenced the efficacy of interventions on both sexual-health outcomes, whereas intervention duration influenced sexually transmitted infection testing.

CONCLUSIONS AND IMPLICATIONS

Interventions aiming to improve condom use are more successful when an interactive component is used. Further research needs to be conducted to reach specific at-risk populations.

Ongoing sexually transmitted disease acquisition and risk-taking behavior among US HIV-infected patients in primary care: implications for prevention interventions

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.

Routine brief risk-reduction counseling with biannual STD testing reduces STD incidence among HIV-infected men who have sex with men in care

BACKGROUND

We evaluated whether routine biannual sexually transmitted disease (STD) testing coupled with brief risk-reduction counseling reduces STD incidence and high-risk behaviors.

METHODS

The SUN study is a prospective observational HIV cohort study conducted in 4 US cities. At enrollment and every 6 months thereafter, participants completed a behavioral survey and were screened for STDs, and if diagnosed, were treated. Medical providers conducted brief risk-reduction counseling with all patients. Among men who have sex with men (MSM), we examined trends in STD incidence and rates of self-reported risk behaviors before and after exposure to the risk-reduction intervention. The "preintervention" visit was the study visit that was at least 6 months after enrollment STD screening and treatment and at which the participant was first exposed to the intervention. The "postintervention" visit was 12 months later.

RESULTS

Among 216 MSM with complete STD and behavioral data, median age was 44.5 years; 77% were non-Hispanic white; 83% were on highly active antiretroviral treatment; 84% had an HIV RNA level <400 copies/mL and the median CD4 (cluster of differentiation 4) count was 511 cells/mm. Twelve months after first exposure to the risk-reduction intervention, STD incidence declined from 8.8% to 4.2% (P = 0.041). Rates of unprotected receptive or insertive anal intercourse with HIV-positive partners increased (19% to 25%, P = 0.024), but did not change with HIV-negative partners or partners of unknown HIV status (24% to 22%, P = 0.590).

CONCLUSIONS

STD incidence declined significantly among HIV-infected MSM after implementing frequent, routine STD testing coupled with risk-reduction counseling. These findings support adoption of routine STD screening and risk-reduction counseling for HIV-infected MSM.

Condom use problems during anal sex among men who have sex with men (MSM): findings from the Safe in the City study

Our research aims were to: (1) assess the prevalence of two condom use problems: breakage or slippage and partial use (delayed application or early removal) among men who have sex with men (MSM) seeking services in urban US STD clinics; and (2) examine the association between these condom use problems and participant, partner and partnership characteristics. Analysis was restricted to HIV-negative MSM who reported having anal sex at least once in the preceding 3 months and who completed both the baseline and 3 month follow-up assessments. Two models were fitted using the generalized estimating equations (GEE) approach. A total of 263 MSM (median age=32 years) reported 990 partnerships. Partnerships with no condom use 422 (42.6%) were excluded. Thus, 207 MSM and 568 partnerships were included. Among condom users, 100% use was reported within 454 partnerships (79.9%) and <100% within 114 (20.1%), and 21(3.7%) reported both condom use problems, 25 (4.4%) reported only breakage, 67 (11.8%) reported only partial use, and 455 (80.1%) reported no errors. The breakage or slippage and partial use rates per condom used were 3.4% and 11.2%, respectively. A significantly higher rate of breakage or slippage occurred among non-main partnerships. Characteristics associated with increased odds for condom breakage or slippage were: lower education level (OR=2.78; CI: 1.1-7.5), non-main partner status (OR=4.1; CI: 1.5-11.7), and drunk or high during sex (OR=2.0; CI: 1.1-3.8), and for partial use: lower education level (OR=2.6; CI: 1.0-6.6), perceived partner sexually transmitted infections (STI) risk (OR=2.4; CI: 1.3-4.2), and inconsistent condom use (OR=3.7; CI: 2.0-6.6). A high percentage of MSM partnerships reported no condom use and among condom users, a sizable proportion did not use them consistently or correctly. MSM may benefit from interventions designed to increase proficiency for condom use with a particular focus on the behaviors of inconsistent and partial condom use.

Emerging issues in management of sexually transmitted diseases in HIV infection

Sexually transmitted diseases (STDs) occur often among sexually active persons with HIV infection. Incident STDs may complicate the course of HIV infection and potentiate HIV transmission in the coinfected individual by mucosal disruption and an increase in HIV concentration in ulcers and involved mucous membranes. Conducting ongoing periodic sexual risk assessments in HIV-positive patients in routine medical care is critical to identifying asymptomatic infections. HIV clinicians should be familiar with updated recommendations for screening, diagnosis, and treatment of bacterial and viral STDs, including those specific to HIV infection. This article addresses emerging issues in the management of STDs in HIV-infected persons and summarizes the latest evidence that can be applied to clinical decision-making in this population.

Prevalence and correlates of HIV and syphilis infections among men who have sex with men in Chongqing Municipality, China

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.

An integrated model of care to counter high incidence of HIV and sexually transmitted diseases in men who have sex with men - initial analysis of service utilizers in Zurich

BACKGROUND

As other countries, Switzerland experiences a high or even rising incidence of HIV and sexually transmitted infections (STI) among men who have sex with men (MSM). An outpatient clinic for gay men ("Checkpoint") was opened in 2006 in Zurich (Switzerland) in order to provide sexual health services. The clinic provides counselling, testing, medical treatment and follow-up at one location under an "open-door-policy" and with a high level of personal continuity. We describe first experiences with the new service and report the characteristics of the population that utilized it.

METHODS

During the 6-month evaluation period, individuals who requested counselling, testing or treatment were asked to participate in a survey at their first visit prior to the consultation. The instrument includes questions regarding personal data, reasons for presenting, sexual behaviour, and risk situations. Number and results of HIV/STI tests and treatments for STI were also recorded.

RESULTS

During the evaluation period, 632 consultations were conducted and 247 patients were seen by the physician. 406 HIV tests were performed (3.4% positive). 402 men completed the entry survey (64% of all consultations). The majority of respondents had 4 and more partners during the last 12 months and engaged in either receptive, insertive or both forms of anal intercourse. More than half of the responders used drugs or alcohol to get to know other men or in conjunction with sexual activity (42% infrequently, 10% frequently and 0.5% used drugs always). The main reasons for requesting testing were a prior risk situation (46.3%), followed by routine screening without a prior risk situation (24.1%) and clarification of HIV/STI status due to a new relationship (29.6%). A fifth of men that consulted the service had no history of prior tests for HIV or other STIs.

CONCLUSION

Since its first months of activity, the service achieved high levels of recognition, acceptance and demand in the MSM community. Contrary to common concepts of "testing clinics", the Checkpoint service provides post-exposure prophylaxis, HIV and STI treatment, psychological support and counselling and general medical care. It thus follows a holistic approach to health in the MSM community with the particular aim to serve as a "door opener" between the established system of care and those men that have no access to, or for any reason hesitate to utilize traditional health care.

Epidemic infectious syphilis in inner Sydney - strengthening enhanced surveillance

OBJECTIVE

To report the results of a 2001-04 enhanced syphilis surveillance program in south-eastern Sydney and a subset of cases from the Sydney Sexual Health Centre (SSHC).

METHODS

For all laboratory syphilis notifications, a questionnaire was sent to the referring doctor requesting demographic data, clinical information about disease classification and the presence of symptoms. Sex of partner/s and HIV status were collected from a subset of cases seen at SSHC.

RESULTS

During 2001-04, 1,275 syphilis notifications were received and 1,112 (87%) were able to be classified as 361 (28%) cases of infectious syphilis, 221 (17%) non-infectious syphilis and 530 (42%) treated syphilis. From mid 2002, an increase in the number of infectious syphilis notifications was noted. Of the 361 cases of infectious syphilis, most were in men (348, 97%). From a subset of 47 cases of infectious syphilis from SSHC, 43 (91%) were in gay men and nine (21%) had concurrent HIV infection.

CONCLUSIONS

Inner Sydney has recently experienced a rapid increase in infectious syphilis affecting a defined population: men, aged 30-39, English speaking and Australian born. These results support recent reports of outbreaks among men who have sex with men, but without routine collection of additional risk factors control programs may be misguided.

IMPLICATIONS

In light of the review of the NSW Public Health Act 1991, it is recommended that reducing barriers to the collection of HIV status and sex of sexual partners in de-identified syphilis notifications be explored as a matter of urgency.

Primary care health issues among men who have sex with men

PURPOSE

The purpose of the article is to examine "appropriate" health care for men who have sex with men (MSM), which is not to suggest "special" health care. As a group, MSM are at increased risk for sexually transmitted infections, anal cancer, and mental health disorders. Focus areas in this article will address health issues that the primary care nurse practitioner (NP) may encounter in clinical practice: anal carcinoma, sexually transmitted diseases (STDs), high-risk sexual practices, depression, and substance abuse were topics chosen for inclusion in this article. These topics were among those highlighted in the Healthy People 2010 Companion Document for LGBT Health, which served to examine the healthcare disparities and lack of access to needed services related to sexual orientation.

DATA SOURCE

Extensive literature review of research articles, journals, clinical practice guidelines, books, and public health department Internet Web sites.

CONCLUSIONS

There are unique health disparities that exist for MSM related to social, emotional, and mental health factors, in addition to physical issues such as STDs. There is an increasing need for primary care providers to be aware of these disparities, as well as the factors that influence these disparities, in order to provide multidimensional care and health counseling that is unique to NP practice.

IMPLICATIONS FOR PRACTICE

Both the primary care NP and the patient should be aware of the unique healthcare issues among MSM that should be incorporated into the patient's routine health maintenance program. As primary care providers, it is within the standards of practice for NPs to provide culturally competent care, along with health promotion and disease prevention for MSM.

Managing Syphilis in the HIV-infected Patient

Syphilis has re-emerged in the United States and elsewhere, and clinicians caring for HIV-infected patients are challenged with syphilis diagnosis and management decisions. HIV alters the natural history of syphilis to an extent that is poorly understood, and initial presentation may be more varied in coinfected patients. Although commonly available diagnostic assays for syphilis should be interpreted as usual, such tests rely on antibody measurement and may be an imperfect indicator of active infection. Assessment of all available clinical and risk behavior data remains critically important in the diagnosis of syphilis in coinfected patients. Treatment of syphilis in such patients requires stage-appropriate therapy, with careful serologic monitoring to assess response. Clinicians must have heightened appreciation of the role of frequent risk assessment, serologic screening, symptom recognition, and follow-up of treated patients, as well as an understanding of public health functions such as sex partner treatment and communicable disease reporting.
