"I Assumed that He Knows Because He's Seen My Profile": HIV Status Disclosure and Condom Use Decisions Among Men who have Sex with Men (MSM) Using Hookup Apps and Websites

In the present study, we sought to better understand how MSM make decisions about HIV disclosure when using hook-up apps/websites and how these decisions relate to condom use during app/website-facilitated sexual encounters. Semi-structured interviews were conducted with 60 MSM (30% living with HIV) who had used hook-up apps and websites to meet sexual partners within the past three months. Results demonstrated a variety of approaches to HIV status disclosure. Some men reported usually discussing HIV status, but others discussed HIV status selectively (e.g., only when asked, when a relationship became more serious). Some men reported that listing one's status in a profile precluded the need to discuss it further. Others noted that leaving an HIV status blank "hinted" at their own or others' HIV positive or negative status. These approaches were closely linked to decisions about condom use. Many men reported serosorting based on inferences or assumptions about partners' HIV status. Together, results highlighted potential gaps in communication that can lead to faulty assumptions about HIV status and subsequent serodiscordant condomless sex and suggest that interventions that promote HIV status disclosure address these potential faulty assumptions.

Missed opportunities for HIV control: Gaps in HIV testing for partners of people living with HIV in Lima, Peru

Introduction

Based on the hypothesis that HIV programs struggle to deliver health services that harmonize necessities of treatment and prevention, we described the outcomes of routinely provided HIV testing to partners of people living with HIV (PLWH) through a secondary analysis of routine data collected at a public hospital in Lima, Peru.

Methods

Among PLWH enrolled in the study center’s HIV program between 2005 and 2014, we identified index cases (IC): PLWH who reported a unique partner not previously enrolled. We grouped partners according to their HIV status as reported by IC and collected data on HIV testing, clinical characteristics and admissions. The main outcome was the frequency of HIV testing among partners with reported unknown/seronegative HIV status.

Results

Out of 1586 PLWH who reported a unique partner at enrollment, 171 had a previously enrolled partner, leaving 1415 (89%) IC. HIV status of the partner was reported as unknown in 571 (40%), seronegative in 325 (23%) and seropositive in 519 (37%). Out of 896 partners in the unknown/seronegative group, 72 (8%) had HIV testing, 42/72 (58%) tested within three months of IC enrollment. Among the 49/72 (68%) who tested positive for HIV, 33 (67%) were enrolled in the HIV program. The proportion in WHO clinical stage IV was lower in enrolled partners compared to IC (37% vs 9%, p = 0.04). Non-tested partners (824) were likely reachable by the hospital, as 297/824 (36%) of their IC were admitted in the study center at least once, 51/243 (21%) female IC had received pregnancy care at the study center, and 401/692 (64%) of IC on antiretroviral therapy had achieved viral suppression, implying frequent visits to the hospital for pill pick-up.

Conclusion

In this setting, HIV testing of partners of PLWH was suboptimal, illustrating missed opportunities for HIV control. Integration of HIV strategies in primarily clinical-oriented services is a challenging need.

A Randomized-Controlled Trial of Computer-based Prevention Counseling for HIV-Positive Persons (HPTN 065)

OBJECTIVE

Decreasing the risk of HIV transmission from HIV-positive individuals is an important public health priority. We evaluated the effectiveness of a computer-based sexual risk reduction counseling intervention (CARE+) among HIV-positive persons enrolled in care.

METHODS

HIV-positive eligible participants (N=1075) were enrolled from 11 care sites in the Bronx, NY and Washington, DC and randomized 1:1 to either a tablet-based self-administered CARE+ intervention or standard of care (SOC). The primary outcome was the proportion of participants reporting any unprotected vaginal/anal sex at last sex, among all partners, HIV-negative or HIV-unknown-status partners and for primary and non-primary partners.

RESULTS

At baseline, 7% of participants in both arms reported unprotected sex with an HIV-negative or HIV-unknown-status partner, while 13% in the CARE+ arm and 17% in the SOC arm reported unprotected sex with any partner. Most participants (88%) were on antiretroviral therapy (ART) at baseline. There was no significant difference in changes over time in unprotected vaginal/anal sex between the CARE+ and SOC arms for any partners (p=0.67) or either HIV-negative or HIV-unknown-status partners (p=0.40). At the Month 12 visit, most participants (85%) either strongly agreed or agreed that computer counseling would be a good addition to in-person counseling by a provider.

CONCLUSION

The CARE+ intervention was not effective at reducing sexual risk behaviors among HIV-positive patients in care, most of whom were on ART. Further research may be warranted around the utility of computer-based counseling for HIV prevention.

Relationships between neighbourhood characteristics and current STI status among HIV-infected and HIV-uninfected women living in the Southern USA: a cross-sectional multilevel analysis

OBJECTIVES

Neighbourhood characteristics (eg, high poverty rates) are associated with STIs among HIV-uninfected women in the USA. However, no multilevel analyses investigating the associations between neighbourhood exposures and STIs have explored these relationships among women living with HIV infection. The objectives of this study were to: (1) examine relationships between neighbourhood characteristics and current STI status and (2) investigate whether the magnitudes and directions of these relationships varied by HIV status in a predominantly HIV-infected cohort of women living in the Southern USA.

METHODS

This cross-sectional multilevel analysis tests relationships between census tract characteristics and current STI status using data from 737 women enrolled at the Women's Interagency HIV Study's southern sites (530 HIV-infected and 207 HIV-uninfected women). Administrative data (eg, US Census) described the census tract-level social disorder (eg, violent crime rate) and social disadvantage (eg, alcohol outlet density) where women lived. Participant-level data were gathered via survey. Testing positive for a current STI was defined as a laboratory-confirmed diagnosis of chlamydia, gonorrhoea, trichomoniasis or syphilis. Hierarchical generalised linear models were used to determine relationships between tract-level characteristics and current STI status, and to test whether these relationships varied by HIV status.

RESULTS

Eleven per cent of participants tested positive for at least one current STI. Greater tract-level social disorder (OR=1.34, 95% CI 0.99 to 1.87) and social disadvantage (OR=1.34, 95% CI 0.96 to 1.86) were associated with having a current STI. There was no evidence of additive or multiplicative interaction between tract-level characteristics and HIV status.

CONCLUSIONS

Findings suggest that neighbourhood characteristics may be associated with current STIs among women living in the South, and that relationships do not vary by HIV status. Future research should establish the temporality of these relationships and explore pathways through which neighbourhoods create vulnerability to STIs.

Reducing non-injection drug use in HIV primary care: A randomized trial of brief motivational interviewing, with and without HealthCall, a technology-based enhancement

AIMS

In HIV-infected individuals, non-injection drug use (NIDU) compromises many health outcomes. In HIV primary care, the efficacy of brief motivational interviewing (MI) to reduce NIDU is unknown, and drug users may need greater intervention. We designed an enhancement to MI, HealthCall (HC), for daily patient self-monitoring calls to an interactive voice response (IVR) phone system, and provided participants with periodic personalized feedback. To reduce NIDU among HIV primary care patients, we compared the efficacy of MI+HealthCall to MI-only and an educational control condition.

DESIGN

Participants age >18 with >4days of NIDU during the prior 30days were recruited from large urban HIV primary care clinics. Of the 240 participants, 83 were randomly assigned to control, 77 to MI-only, and 80 to MI+HC. Counselors provided educational control, MI-only or MI+HC at baseline. At 30 and 60days (end-of-treatment), counselors briefly discussed drug use, moods and health behaviors, using HealthCall-generated graphs with MI+HC patients. Primary outcomes (last 30days) were number of days used primary drug (NumDU), and total quantity of primary drug used (dollar amount spent; QuantU), derived from the Time-Line Follow-Back.

FINDINGS

Across all groups, at end-of-treatment, frequency and quantity of NIDU decreased, with significantly greater reductions in the MI-Only group. A twelve-month post-treatment follow-up indicated sustained benefits of MI+HC and MI-only relative to control.

CONCLUSIONS

Brief interventions can be successfully used to reduce non-injection drug use in HIV primary care. IVR-based technology may not be sufficiently engaging to be effective. Future studies should investigate mobile technology to deliver a more engaging version of HealthCall to diverse substance abusing populations.

Bacterial sexually transmitted infections among HIV-infected patients in the United States: estimates from the Medical Monitoring Project

BACKGROUND

Bacterial sexually transmitted infections may facilitate HIV transmission. Bacterial sexually transmitted infection testing is recommended for sexually active HIV-infected patients annually and more frequently for those at elevated sexual risk. We estimated percentages of HIV-infected patients in the United States receiving at least one syphilis, gonorrhea, or chlamydia test, and repeat (≥2 tests, ≥3 months apart) tests for any of these sexually transmitted infections from mid-2008 through mid-2010.

DESIGN

The Medical Monitoring Project collects behavioral and clinical characteristics of HIV-infected adults receiving medical care in the United States using nationally representative sampling.

METHODS

Sexual activity included self-reported oral, vaginal, or anal sex in the past 12 months. Participants reporting more than 1 sexual partner or illicit drug use before/during sex in the past year were classified as having elevated sexual risk. Among participants with only 1 sex partner and no drug use before/during sex, those reporting consistent condom use were classified as low risk; those reporting sex without a condom (or for whom this was unknown) were classified as at elevated sexual risk only if they considered their sex partner to be a casual partner, or if their partner was HIV-negative or partner HIV status was unknown. Bacterial sexually transmitted infection testing was ascertained through medical record abstraction.

RESULTS

Among sexually active patients, 55% were tested at least once in 12 months for syphilis, whereas 23% and 24% received at least one gonorrhea and chlamydia test, respectively. Syphilis testing did not vary by sex/sexual orientation. Receipt of at least 3 CD4+ T-lymphocyte cell counts and/or HIV viral load tests in 12 months was associated with syphilis testing in men who have sex with men (MSM), men who have sex with women only, and women. Chlamydia testing was significantly higher in sexually active women (30%) compared with men who have sex with women only (19%), but not compared with MSM (22%). Forty-six percent of MSM were at elevated sexual risk; 26% of these MSM received repeat syphilis testing, whereas repeat testing for gonorrhea and chlamydia was only 7% for each infection.

CONCLUSIONS

Bacterial sexually transmitted infection testing among sexually active HIV-infected patients was low, particularly for those at elevated sexual risk. Patient encounters in which CD4+ T-lymphocyte cell counts and/or HIV viral load testing occurs present opportunities for increased bacterial sexually transmitted infection testing.

Prevalence of sexually transmitted infections in at-risk adolescent females at a comprehensive, stand-alone adolescent health center in New York City

BACKGROUND

Sexually transmitted infections (STIs) are common among adolescents, and multiple STIs over one's lifetime can increase health risks. Few studies have assessed lifetime STI prevalence. This study evaluates minority, underserved adolescents' self-reported lifetime STI history and objective STI rates.

METHODS

Lifetime STI rates of female patients at an urban adolescent health center were obtained from self-administered questionnaires. Additionally, STI test results were retrieved from electronic medical records.

RESULTS

Patients reported a high lifetime prevalence of STIs. By comparing self-report and objective data, underreporting was identified for chlamydia, gonorrhea, and herpes.

CONCLUSIONS

STI rates in at-risk adolescent females are higher than in the general population and remain elevated over time. Lifetime STI reports could expand our understanding of sexual health and should be further studied. Underreporting, which may increase health risks and hinder health care delivery, requires further investigation. Improvements in STI screening and prevention targeting at-risk populations are warranted.

Μanagement of patients with hepatitis B and C before and after liver and kidney transplantation

New nucleos(t)ide analogues (NAs) with high genetic barrier to hepatitis B virus (HBV) resistance (such as entecavir, tenofovir) have improved the prognosis of patients with HBV decompensated cirrhosis and have prevented HBV recurrence after liver transplantation (LT). NAs are considered the most proper approach for HBV infection in patients under renal replacement therapy but their doses should be adjusted according to the patient's creatinine clearance. In addition, physicians should be aware of the potential nephrotoxicity. However, patients with chronic hepatitis C and decompensated cirrhosis can receive only one therapeutic option before LT, as well as for Hepatitis C virus (HCV) recurrence after LT, which is the combination of subcutaneous Peg-IFN and ribavirin. Generally, therapy for HCV after renal transplantation should be avoided. Although the optimal antiviral therapy for HCV infection has not been established, attention has turned to a new, oral direct acting antiviral treatment which marks a promising strategy in prognosis and in amelioration of these diseases.

Sexual risk behavior and viremia among men who have sex with men in the HIV Outpatient Study, United States, 2007-2010

BACKGROUND

Recent US data on unsafe sexual behaviors among viremic HIV-infected men who have sex with men (MSM) are limited.

METHOD

Using data abstracted from medical records of the participants in the HIV Outpatient Study (HOPS) and a supplemental behavioral survey, we assessed the frequency of high-risk sexual practices among HIV-infected MSM in care and examined the factors associated with risky sexual practices. We also compared the frequency of unprotected anal sex (UAS) with HIV-negative or unknown serostatus partners among viremic (HIV viral load ≥400 copies per milliliter) vs virologically suppressed (HIV viral load <400 copies per milliliter) MSM.

RESULTS

Among 902 HIV-infected MSM surveyed, 704 (78%) reported having sex in the past 6 months, of whom 54% reported UAS (37% insertive, 42% receptive) and 40% UAS with a male partner who was HIV-negative or of unknown serostatus (24% insertive, 31% receptive). In multivariable regression with an outcome of engaging in any UAS with a male partner who was HIV-negative or of unknown serostatus, MSM aged <50 years, who reported injection drug use risk, had ≥2 sex partners, and who disclosed their HIV status to some but not to all of their sex partners were more likely to report this practice. Among MSM who reported any UAS, 15% were viremic; frequency of the UAS did not differ between viremic and virologically suppressed MSM.

CONCLUSIONS

The high frequency of UAS with HIV-negative or unknown-status partners among HIV-infected MSM in care suggests the need for targeted prevention strategies for this population.

Impact of a computer-assisted, provider-delivered intervention on sexual risk behaviors in HIV-positive men who have sex with men (MSM) in a primary care setting

Innovative strategies are needed to assist providers with delivering secondary HIV prevention in the primary care setting. This longitudinal HIV clinic-based study conducted from 2004-2007 in a Birmingham, Alabama HIV primary care clinic tested a computer-assisted, provider-delivered intervention designed to increase condom use with oral, anal and vaginal sex, decrease numbers of sexual partners and increase HIV disclosure among HIV-positive men-who-have-sex-with-men (MSM). Significant declines were found for the number of unprotected insertive anal intercourse acts with HIV+ male partners during the intervention period (p = 0.0003) and with HIV-/UK male partners (p = 0.0007), as well as a 47% reduction in the number of male sexual partners within the preceding 6 months compared with baseline (p = 0.0008). These findings confirm and extend prior reports by demonstrating the effectiveness of computer-assisted, provider-delivered messaging to accomplish risk reduction in patients in the HIV primary care setting.

An integrated approach for antiretroviral adherence and secondary HIV transmission risk-reduction support by nurses in Kenya

Ongoing antiretroviral therapy (ART) adherence and secondary HIV transmission-risk reduction (positive prevention) support are needed in resource-limited settings. We evaluated a nurse-delivered counseling intervention in Kenya. We trained 90 nurses on a brief counseling algorithm that comprised ART and sexual-risk assessment, risk-reduction messages, and health-promotion planning. Self-reported measures were assessed before, immediately after, and 2 months post-training. Consistent ART adherence assessment was reported by 29% of nurses at baseline and 66% at 2 months post-training (p < .001). Assessment of patient sexual behaviors was 25% at baseline and 60% at 2 months post-training (p < .001). Nurse practice behaviors recommended in the counseling algorithm improved significantly at 2 months post-training compared with baseline, odds ratios 4.30-10.50. We found that training nurses in clinical counseling for ART adherence and positive prevention is feasible. Future studies should test impact of nurse counseling on patient outcomes in resource-limited settings.

Messages HIV clinicians use in prevention with positives interventions

Prevention with Positives (PwP) is a component of the US HIV prevention strategy that targets HIV-infected persons who are aware of their seropositive status. This paper examines the use of prevention messages by clinical providers during the PwP intervention period of the US Health Resources and Services Administration's Special Projects of National Significance program. Quantitative approaches were used to learn which prevention topics were most discussed and qualitative interviews were also utilized to better understand the clinician perspective in providing prevention counseling. At 12-month follow-up, there was a significant increase in the percent of patients receiving all PwP counseling messages (p<0.01). Providers reported discussing safer sex with 91% of patients when sexually transmitted infection (STI) screening was conducted during a visit, an increase from baseline (83.5%). The percent of providers reporting they regularly explained the risk of superinfection to their clients also increased from 75% at baseline to 90% at 12-month follow up (p<0.001). Qualitative data suggest that providers prioritize individual care over public health approaches to PwP in counseling. Discussing superinfection offered providers a way to discuss HIV prevention from a non-judgmental clinical perspective while focusing on a patient-centered philosophy of care. However, the threat of superinfection may not be the best counseling option. Examples such as STI screening, giving messages to reduce the number of sexual partners and adherence to medication, are more evidence-based approaches to changing HIV transmission risk behavior and may be more important in PwP. Findings suggest that in order for HIV care providers to incorporate HIV prevention discussions into their practice, acceptable approaches to speaking about risk behavior and prevention of HIV transmission must be developed.

Interventions to prevent sexually transmitted infections, including HIV infection

The Centers for Disease Control and Prevention (CDC) Sexually Transmitted Disease (STD) Treatment Guidelines were last updated in 2006. To update the "Clinical Guide to Prevention Services" section of the 2010 CDC STD Treatment Guidelines, we reviewed the recent science with reference to interventions designed to prevent acquisition of STDs, including human immunodeficiency virus (HIV) infection. Major interval developments include (1) licensure and uptake of immunization against genital human papillomavirus, (2) validation of male circumcision as a potent prevention tool against acquisition of HIV and some other sexually transmitted infections (STIs), (3) failure of a promising HIV vaccine candidate to afford protection against HIV acquisition, (4) encouragement about the use of antiretroviral agents as preexposure prophylaxis to reduce risk of HIV and herpes simplex virus acquisition, (5) enhanced emphasis on expedited partner management and rescreening for persons infected with Chlamydia trachomatis and Neisseria gonorrhoeae, (6) recognition that behavioral interventions will be needed to address a new trend of sexually transmitted hepatitis C among men who have sex with men, and (7) the availability of a modified female condom. A range of preventive interventions is needed to reduce the risks of acquiring STI, including HIV infection, among sexually active people, and a flexible approach targeted to specific populations should integrate combinations of biomedical, behavioral, and structural interventions. These would ideally involve an array of prevention contexts, including (1) communications and practices among sexual partners, (2) transactions between individual clients and their healthcare providers, and (3) comprehensive population-level strategies for prioritizing prevention research, ensuring accurate outcome assessment, and formulating health policy.

HIV intervention for providers study: a randomized controlled trial of a clinician-delivered HIV risk-reduction intervention for HIV-positive people

Clinician-delivered prevention interventions offer an opportunity to integrate risk-reduction counseling as a routine part of medical care. The HIV Intervention for Providers study, a randomized controlled trial, developed and tested a medical provider HIV prevention training intervention in 4 northern California HIV care clinics. Providers were assigned to either the intervention or control condition (usual care). The intervention arm received a 4-hour training on assessing sexual risk behavior with HIV-positive patients and delivering risk-reduction-oriented prevention messages to patients who reported risk behaviors with HIV-uninfected or unknown-status partners. To compare the efficacy of the intervention versus control on transmission risk behavior, 386 patients of the randomized providers were enrolled. Over six-months of follow-up, patients whose providers were assigned the intervention reported a relative increase in provider-patient discussions of safer sex (OR = 1.49; 95% CI = 1.06 to 2.09), assessment of sexual activity (OR = 1.60; 95% CI = 1.05 to 2.45), and a significant decrease in the number of sexual partners (OR = 0.49, 95% CI = 0.26 to 0.92). These findings show that a brief intervention to train HIV providers to identify risk and provide a prevention message results in increased prevention conversations and significantly reduced the mean number of sexual partners reported by HIV-positive patients.

Trends in sexually transmitted diseases and risky behaviors among HIV-infected patients at an outpatient clinic in southern Taiwan

BACKGROUND

Little is known about the prevalence of concurrent sexually transmitted diseases (STDs) and associated risky behaviors among patients living with HIV in Taiwan.

METHODS

A cross-sectional study was conducted using HIV-infected patients who attended the outpatient clinic of an AIDS referral center in Taiwan between August 2005 and December 2005. Participants received physical examinations, serological tests for syphilis, and urine tests for both Neisseria gonorrhoea and Chlamydia trachomatis by the polymerase chain reaction method. A self-administered questionnaire concerning sexual behaviors and history of STDs was collected. The history of repeat STDs since the diagnosis of HIV was retrieved by chart review.

RESULTS

A total of 123 HIV-infected patients were enrolled. Among these, 43.1% reported a history of STDs before the diagnosis of HIV infection. A total of 36.1% had concurrent STDs at the time of HIV diagnosis, and 8.9% were diagnosed with STDs at enrollment. Syphilis was the most common STD. The rate of condom usage for the last sexual intercourse was 68.3%, and the use of illicit/recreational drugs was 7.9%. HIV diagnosis within 3 months (odds ratio [OR], 46.5; 95% confidence interval [CI], 3.9-552.0; P = 0.002) and repeated infection with STDs since HIV diagnosis (OR, 18.7; 95% CI, 1.7-201.6; P = 0.016) were 2 independent predictors of participants with active STDs at enrollment.

CONCLUSION

HIV-infected individuals had a high rate of concurrent STDs before and after diagnosis of HIV infection. Our study findings highlight the importance of secondary prevention strategies for patients living with HIV.

Parent-adolescent sexual communication: associations of condom use with condom discussions

This study investigated the relationship between parent-teen sexual communication, discussion of condoms, and condom use among adolescents in mental health treatment. Adolescents with a history of sexual intercourse and their parents completed questionnaires assessing adolescent sexual risk behavior, sexual communication, and discussion of sexual topics. Greater condom use by adolescents was associated with parent-adolescent condom discussion but was not associated with openness in sexual communication. Seventy-six percent of adolescents reported that parents had discussed condoms with them and these discussions were significantly associated with protected sexual acts. In a logistic regression, accounting for age, gender, race, and psychiatric diagnosis teens that discussed condoms with their parent were more likely to report condom use at last sex. Increasing direct communication about condoms may be an important step in increasing adolescent's safer sex behavior. Mental health disorders and family distress may make such discussions challenging but are not an insurmountable barrier to direct discussions about condoms.

Population prevalence of reported and unreported HIV and related behaviors among the household adult population in New York City, 2004

BACKGROUND

Surveillance for HIV likely underestimates infection among the general population: 25% of US residents are estimated to be unaware of their HIV infection.

OBJECTIVE

To determine the prevalence of HIV infection and risk behaviors among New York City (NYC) adults and compare these with surveillance findings.

METHODS

The NYC Health and Nutrition Examination Survey (HANES) provided the first opportunity to estimate population-based HIV prevalence among NYC adults. It was conducted in 2004 among a representative sample of adults > 20 years. Previously reported HIV infection was identified from the NYC HIV/AIDS Surveillance Registry. A blinded HIV serosurvey was conducted on archived blood samples of 1626 NYC HANES participants. Data were used to estimate prevalence for HIV infection, unreported infections, high-risk activities, and self-perceived risk.

RESULTS

Overall, 18.1% engaged in one or more risky sexual/needle-use behaviors, of which 92.2% considered themselves at low or no risk of HIV or another sexually transmitted disease. HIV occurred in 21 individuals (prevalence 1.4%; 95% confidence interval (CI), 0.8-2.5]; one infection (5%; 95% CI, 0.7-29.9) was not reported previously and possibly undiagnosed. HIV infection was significantly elevated in those with herpes simplex virus 2 (4%), men who have sex with men (14%), and needle-users (21%) (P < 0.01).

CONCLUSIONS

Among NYC adults, HIV prevalence was consistent with surveillance findings overall. The proportion of unreported HIV was less than estimated nationally, but findings were limited by sample size. Most adults with risky behaviors perceived themselves to be at minimal risk, highlighting the need for risk reduction and routine HIV screening.

Internet social support groups as moral agents: the ethical dynamics of HIV+ status disclosure

This paper examines how, on Internet HIV/AIDS support groups, participants discuss the ethics of disclosing HIV seropositivity to partners. The data consist of all mentions of disclosure culled from over 16,000 pages overall of posts from 16 different groups, hosted on seven separate sites. The paper focuses on two main questions. First, apart from providing support and information, did the groups also debate moral dilemmas (and, despite groups' common perception as 'safe spaces' for non-judgmental exchanges, did these discussions include moral judgments and conflicts)? Secondly, did use of this new medium generate a new, alternative ethical discourse, or merely replicate existing discourses? The data demonstrate that online support groups did engage in debating, and trying verbally to enforce, certain views of the ethics of seropositivity disclosure. The most common view advocated full disclosure, though a range of positions existed. Unlike with most online support groups described elsewhere, these discussions often included harshly-expressed moral judgments. The groups did not generate a truly new, alternative discourse, but served as clearinghouses for and transmitters of existing 'off-line' discourses, both mainstream and alternative. Implications and limitations of the present study, and areas for further research, are discussed.

The Treatment Advocacy Program--Sinai: a peer-based HIV prevention intervention for working with African American HIV-infected persons

As HIV/AIDS continues to disproportionately affect African American communities, there is a growing need for empirically based, culturally appropriate, tailored interventions for this clientele. As part of a Health Resources and Services Administration (HRSA)/Special Projects of National Significance (SPNS) initiative to increase prevention amongst those living with HIV, we implemented the Treatment Advocacy Program Intervention at Mount Sinai Hospital in Chicago, IL, USA. The main goal of the intervention was to help patients increase their medication adherence and sexual safety skills. This paper describes the rationale for implementing this peer-based HIV-prevention intervention, discusses how the intervention was tailored to work within our low socio-economic status, urban patient population, and reviews the training and quality assurance activities needed to integrate the intervention into our primary care clinic. We review the intervention content in detail, including the structure of the multiple, one-on-one education sessions, and the core topics covered (medication adherence and sexual safety). Finally, we discuss the challenges in implementing this program, many of which arise from the chaotic social situations that our patients experience.

Ongoing risk behavior among persons with HIV in medical care

We surveyed randomly selected patients in the largest HIV clinic in Seattle, WA in 2005 and 2006. A total of 397 patients completed usable surveys. Twenty-seven percent of men who have sex with men (MSM) and 22% of women or heterosexual men reported having non-concordant unprotected anal or vaginal intercourse in the preceding year. Compared to 2005, more MSM in 2006 reported meeting a sex partner via the Internet (15% vs. 33%), and fewer met partners in bathhouses (23% vs. 13%). Twenty-four percent of MSM reported deciding not to have sex with a potential partner because he was HIV negative, and 31% of MSM reported that another man had decided not to have sex with them because they were HIV positive. Among all participants, 22% had told a sex partner they were HIV negative since their HIV diagnosis. These findings demonstrate the persistence of high-risk behavior among persons with HIV, a rapid increase in the use of the Internet among MSM to find sex partners, and provide direct evidence for serosorting among MSM.

[Prevention practices of primary health care physicians in Switzerland in the context of the HIV/Aids epidemic: changes between 1990 and 2002]

BACKGROUND

Individual preventive counseling offered to the general public by private doctors working in primary health care is an essential component of the Swiss National Aids Prevention strategy. Surveys were conducted to assess to what extent they fulfill this role and how this may have changed over time.

METHODS

Three cross-sectional surveys were conducted in 1990, 1995, and 2002 by anonymous mailed questionnaire in a random sample of primary health care physicians. Dimensions of the physicians HIV prevention practices investigated were: practice of HIV risk assessment, content and frequency of HIV pretest counseling, and, in 2002 only, care of patients living with HIV/AIDS. Trends over the 12-year period were calculated; logistic regressions were performed to investigate factors associated with the frequency of counseling given to HIV positive patients.

RESULTS

Risk assessment has increased dramatically over the period for certain groups of patients (patients requesting contraception, young people and new patients). In 2002, routine screening is often or always performed by 93% of physicians for intravenous drug patients or patients with a sexually transmitted infection; 77% for homosexuals; 76% for patients requesting contraception; 63% for young people. It is less frequent in other groups (migrants: 40%; separated/divorced patients: 29%). More than half of physicians care for patients with HIV. Around two-thirds of physicians regularly discuss with their HIV positive patients issues related to patients' professional, social and private life. There are few differences among specialties regarding the propensity to discuss these topics.

CONCLUSION

Prevention activities by primary care physicians have increased in the last decade. Nonetheless, potential for increased prevention still exists in some areas of risk assessment and counseling.

HIV/AIDS: Management of Herpes Simplex Virus Type 2 Infection in HIV Type 1–Infected Persons

Human immunodeficiency virus type 1 (HIV-1)-infected persons have high rates of herpes simplex virus type 2 (HSV-2) infection, ranging from 50% to 90% in studies of HIV-infected populations from different parts of the world. Genital herpes in persons with HIV type 1 (HIV-1) infection is associated with more-severe and chronic lesions, as well as increased rates of asymptomatic genital shedding of HSV-2. Nucleoside analogues (acyclovir, valacyclovir, and famciclovir) decrease the frequency and severity of HSV-2 recurrences and asymptomatic HSV-2 reactivation and are effective, safe, well-tolerated drugs in patients with HIV-1 infection. These anti-HSV drugs may result in additional clinical and public health benefits for persons with HIV-1 and HSV-2 coinfection by decreasing HIV-1 levels in the blood and genital tract. Given these benefits, HIV-1-infected persons should be routinely tested for HSV-2 infection using type-specific serologic tests. Persons with HSV-2 infection should be offered HSV-2 education and treatment options. Studies to quantify the potential clinical and public health benefits of treating individuals who have HIV-1 and HSV-2 coinfection with anti-HSV therapy are underway.

Illicit drug use and HIV-1 disease progression: a longitudinal study in the era of highly active antiretroviral therapy

This study assessed the association between longitudinal patterns of illicit drug use and clinical progression of human immunodeficiency virus (HIV) disease. Confidential computer-based interviews, which addressed illicit drug use and other factors, were completed by HIV-infected participants in Baltimore, Maryland, at 6-month intervals from 1998 onward. To assess this association, the authors used a random-effects model in which clinically defined opportunistic conditions were linked to self-reported periods of drug use, enabling four categories of drug use to be distinguished: nonusers, intermittent users during abstinent periods, intermittent users during active periods, and persistent users. Included in the analysis were 1,851 participants who completed > or = 1 survey. For participants who used drugs intermittently over time, the risk of developing new opportunistic conditions during periods of abstinence was similar to that for those who never used drugs (odds ratio = 1.2, 95% confidence interval: 0.9, 1.7). In contrast, compared with that for nonusers, the risk of opportunistic infection was significantly higher for intermittent drug users during periods of active use (odds ratio = 2.2, 95% confidence interval: 1.4, 2.9) and for persistent drug users (odds ratio = 1.9, 95% confidence interval: 1.2, 2.8). Active drug use is temporally linked to HIV disease progression and mortality. Effectively targeting and treating active substance abuse in HIV treatment settings may provide a mechanism to improve clinical outcomes.

Sexual behaviors and sexual risk in a prospective cohort of HIV-positive men and women in New York City, 1994-2002: implications for prevention

As an ever-increasing number of people infected with HIV are living longer, healthier lives, concerns about continued transmission are growing along with an awareness of the need to develop "prevention for positives." This study of HIV-positive adults in New York City is the first examination of patterns of sexual behavior in a large, representative cohort of HIV-infected individuals followed over an extended time period. A total of 968 HIV-positive adults were interviewed every 6-12 months between 1994 and 2002 and reported considerable variability in sexual behaviors over time. Many persons were not sexually active at all for months at a time; some continued to have multiple partners. Over one third of the cohort had one or more periods when they had engaged in unprotected sex with a partner who was HIV-negative or status unknown (unsafe sex) and one in five reported exchanging sex. Periods of unsafe sex alternated with periods of safer sex. Predictors of sexual risk varied by gender, and among men who had sex with men, and men sexually active with women only. Contextual factors such as partner relations, housing status, and receipt of HIV services were as important as individual attributes as predictors of unsafe sex and sex exchange. The variability observed in sexual risk behavior reported over time provides new insight into the importance of engaging persons living with HIV in ongoing prevention programs.

The population effectiveness of highly active antiretroviral therapy: Are good drugs good enough?

Despite the success of highly active antiretroviral therapy (HAART) at reducing mortality from HIV infection, there is evidence that it is not reaching the all of the population that needs it, even in the developed world. To be maximally effective at the population level, all persons with HIV infection must be diagnosed; those persons with an indication for HAART must enter care, must receive HAART, and then must adhere to appointments and, finally, HAART itself. There is considerable evidence that significant portions of the population infected with HIV have not completed all of these steps of HIV care even in the developed world. Although new medications to treat HIV are certainly needed, significant improvements in viral, immunologic, and clinical outcomes could be achieved from improving timely diagnosis, access to HAART, and adherence to appointments, as well as adherence to HAART.

A randomized controlled trial to reduce HIV transmission risk behaviors and sexually transmitted diseases among women living with HIV: The WiLLOW Program

OBJECTIVE

To evaluate the efficacy of an intervention to reduce HIV transmission risk behaviors and sexually transmitted diseases (STDs) and enhance HIV-preventive psychosocial and structural factors among women living with HIV.

DESIGN

A randomized controlled trial of 366 women living with HIV in Alabama and Georgia.

INTERVENTION

The intervention emphasized gender pride, maintaining current and identifying new network members, HIV transmission knowledge, communication and condom use skills, and healthy relationships.

PRIMARY OUTCOME

Unprotected vaginal intercourse. OTHER OUTCOMES: Proportion never used condoms, incident STDs, psychosocial factors, and number of supportive network members.

RESULTS

Over the 12-month follow-up, women in the WiLLOW intervention, relative to the comparison, reported fewer episodes of unprotected vaginal intercourse (1.8 vs. 2.5; P = 0.022); were less likely to report never using condoms (odds ratio [OR] = 0.27; P = 0.008); had a lower incidence of bacterial infections (Chlamydia and gonorrhea) (OR = 0.19; P = 0.006); reported greater HIV knowledge and condom use self-efficacy, more network members, fewer beliefs that condoms interfere with sex, and fewer partner-related barriers to condom use; and demonstrated greater skill in using condoms.

CONCLUSION

This is the first trial to demonstrate reductions in risky sexual behavior and incident bacterial STDs and to enhance HIV-preventive psychosocial and structural factors among women living with HIV.

Patients referred to an urban HIV clinic frequently fail to establish care: factors predicting failure

To measure the success with which patients newly entering outpatient care establish regular care, and assess whether race/ethnicity was a predictive factor, we conducted a medical record review of new patients seen 20 April 1998 to 31 December 1998 at The Thomas Street Clinic, a county clinic for uninsured persons. Patients were considered 'not established' if they never saw a physician in the 6 months after intake (the 'initial period'), 'poorly established' if seen but a > 6-month gap in care began in the initial period, and 'established' if there were no such gaps. Of 404 patients, 11% were 'not established', 37% 'poorly established', and 53% 'established'. Injection drug use as HIV risk factor (IDU), admitted current alcohol and drug use, age < 35 years, and CD4 count > or = 200 cells/mm(3) were most common in the 'not established' group and least common in the 'established' group. In multivariate ordinal logistic regression, difficulty establishing care was associated with IDU, admitted current alcohol use, and admitted former drug use. Age > 35 years was protective. Half the indigent patients entering care in this single-site study fail to establish regular care. Substance use and younger age are predictors of failure to establish care.

Sexually transmitted disease testing protocols, sexually transmitted disease testing, and discussion of sexual behaviors in HIV clinics in Los Angeles County

OBJECTIVE/GOAL

The objective of this study was to evaluate the use of written protocols for sexually transmitted disease (STD) screening, the frequency and types of STD tests performed, and the occurrence and frequency of obtaining sexual risk assessments among HIV clinics.

STUDY

A survey was administered to 36 medical directors, clinic directors, and HIV providers representing 48 HIV healthcare clinics in Los Angeles.

RESULTS

The use of a written or electronic protocol for STD testing was reported by 50% of clinics. Clinics with written or electronic STD protocols were significantly more likely to report questioning patients at each visit regarding their sexual practices (prevalence ratio, 2.2; 95% confidence interval, 1.4-3.4). Clinics with written or electronic protocols were not more likely to report more frequent STD testing.

CONCLUSIONS

Written or electronic protocols for STD testing may promote sexual risk assessment questioning among HIV healthcare providers and may help to ensure STD testing per Centers for Disease Control and Prevention/IDSA guidelines for HIV-positive persons at sexual risk.

A National Survey of Clinic Sexual Histories for Sexually Transmitted Infection and HIV Screening

BACKGROUND

Optimal elements of a sexual history for sexually transmitted infection (STI) and HIV risk assessment remain undefined.

GOAL

The goal of this study was to describe sexual histories in use at STI clinics across the United States.

STUDY

This study consisted of a cross-sectional survey of facilities in cities with populations >200,000 (n = 65). Within each city, a public health STI clinic (71% of the sample) or other STI care facility (29%) was randomly selected and sexual history forms were requested. Information was obtained from 48 clinics (74% response).

RESULTS

Most forms recorded information on symptoms and prior STI (96%), condom use (88%), other contraception (85%), and numbers and gender (83%) of sex partners. Common HIV risk questions were injecting drug use (IDU; 94%), sex for drugs or money (58%), and sex with an HIV-positive or IDU partner (52%). Ascertainment of time during which risks occurred (contact periods) varied from the past 14 days to the past 12 months, with only 38% of clinics using any 1 time period. Few histories (17%) incorporated questions for men who have sex with men (MSM). Only 2 (4%) had space to record information about sexual behaviors by the HIV status of the sex partner. Condom use was infrequently assessed specifically for vaginal and anal sex (13%), and condom use problems were rarely explored (10%). Most forms documented STI/HIV counseling, although few (25%) included specific risk reduction plans.

CONCLUSIONS

Sexual histories are highly variable. Although challenging to accomplish, STI/HIV care, surveillance, and prevention may be improved by developing consensus on core questions to be used in sexual histories.

Reductions in transmission risk behaviors in HIV-positive clients receiving prevention case management services: findings from a community demonstration project

Prevention case management (PCM) for HIV-infected persons is an HIV risk reduction intervention designed to assist clients who are aware of their HIV infection and who continue to engage in risk transmission behaviors. PCM combines individual risk reduction counseling with case management to address the psychosocial factors affecting HIV transmission. More than 350 HIV-positive clients participated in PCM in Wisconsin between 2000 and 2003, and 109 completed both baseline and follow-up risk assessments. The percentage of clients reporting risk transmission behaviors, specifically unprotected vaginal intercourse, insertive anal intercourse, or needle sharing with partners of negative or unknown HIV status, declined from 41.3% at baseline to 29.4% at follow-up (p = 0.04). Furthermore, clients showed progression (p < or =.05) through stages of change using Prochaska and DiClemente's transtheoretical model on seven domains related to HIV transmission risk, including personalizing risk of HIV transmission and sexual risk behavior.

Influence of liver fibrosis on highly active antiretroviral therapy-associated hepatotoxicity in patients with HIV and hepatitis C virus coinfection

BACKGROUND

Coinfection with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) is a known risk factor for hepatotoxicity in patients receiving highly active antiretroviral therapy (HAART). The aim of this study was to evaluate the role of HCV-related liver fibrosis in HAART-associated hepatotoxicity.

METHODS

In a prospective study involving 107 patients who underwent liver biopsy, fibrosis was graded according 5 stages, from F0 (no fibrosis) to F4 (cirrhosis). Hepatotoxicity was defined as an increase in levels of aspartate aminotransferase and alanine aminotransferase to >5 times the upper limit of normal, or a >3.5-fold increase if baseline levels were abnormal. The incidence of hepatotoxicity was compared with liver fibrosis stage and with time and composition of HAART.

RESULTS

Overall, 27 patients (25%) had hepatotoxic events (5.1 events/100 person-years of therapy). The incidence was greater for patients with stage F3 or F4 fibrosis (38%) than for those with stage F1 or F2 fibrosis (15%; 7.6 vs. 3 events/100 person-years; relative risk, 2.75; 95% confidence interval, 1.08-6.97; P=.013). Duration of HCV infection, duration of HAART, diagnosis of acquired immunodeficiency syndrome, HCV load, HCV genotype, and nadir CD4(+) cell count did not affect the risk of hepatotoxicity. Of the 86 patients who received nonnucleoside reverse-transcriptase inhibitors (NNRTIs), 11 (13%) developed liver toxicity. In these patients, fibrosis stages F1 and F2 were associated with similar rates of toxicity (3 events/100 person-years for patients who received nevirapine, 3.3 events/100 person-years for those who received efavirenz, and 3.4 events/100 person-years for those who received non-NNRTIs). There was a greater incidence among patients with F3 or F4 fibrosis who received NNRTIs (11.7 events/100 person-years for patients who received nevirapine, and 8.6 events/100 person-years for those who received efavirenz), compared with those who received non-NNRTIs (4 events/100 person-years).

CONCLUSIONS

HAART-associated hepatotoxicity correlates with liver histological stage in patients coinfected with HIV and HCV. There was no difference in hepatotoxicity risk for different antiretroviral therapies in patients with mild-to-moderate fibrosis.

The efficacy of an integrated risk reduction intervention for HIV-positive women with child sexual abuse histories

Child sexual abuse (CSA) is associated with HIV risk behaviors [Bensley, L., Van Eenwyk, J., and Simmons, K. W., 2003.] and more prevalent among women living with HIV than in the general population [Koenig, L. J., and Clark, H., 2004]. This randomized Phase~I clinical trial tested the impact of a culturally congruent psychoeducational intervention designed to reduce sexual risks and increase HIV medication adherence for HIV-positive women with CSA histories. An ethnically diverse sample of 147 women were randomized to two conditions: an 11-session Enhanced Sexual Health Intervention (ESHI) or an attention control. Results based on "intent to treat'' analyses of pre-post changes are reported here. Additional analyses explored whether the observed effects might depend on "intervention dose,'' i.e., number of sessions attended. Women in the ESHI condition reported greater sexual risk reduction than women in the control condition. Although there were no differences between women in the ESHI and control groups on medication adherence, women in the ESHI condition who attended 8 or more sessions reported greater medication adherence at posttest than control women. The findings provide initial support for this culturally and gender-congruent psychoeducational intervention for HIV-positive women with CSA, and highlight the importance of addressing the effects of CSA on sexual risk reduction and medication adherence in preventive interventions for women.

Interventions for Seropositive Injectors—Research and Evaluation

BACKGROUND

Behavioral interventions to address the complex medical and HIV risk reduction needs of HIV-seropositive (HIV-positive) injection drug users (IDUs) are urgently needed. We describe the development of Interventions for Seropositive Injectors-Research and Evaluation (INSPIRE), a randomized controlled trial of an integrated intervention for HIV-positive IDUs, and the characteristics of the baseline sample.

METHODS

HIV-positive IDUs were recruited from community settings in 4 US cities. After completing a baseline assessment, participants who attended the first session were randomly assigned to (1) a 10-session peer mentoring intervention designed to improve utilization of HIV care, to improve adherence to HIV medications, and to reduce sexual and injection risk or (2) an 8-session videotape control. Periodic follow-up for 12 months is ongoing.

RESULTS

A total of 1161 HIV-positive IDUs completed the baseline assessment, and 966 (83%) were randomized. Retention rates are greater than 80% for all follow-up periods. Approximately 79% of baseline participants reported a recent medical visit, 49% were taking highly active antiretroviral therapy, and 19% had an undetectable viral load. Use of injection and noninjection substances was prevalent, and sexual and injection risks were each reported by more than 25% of participants.

CONCLUSION

There is a need for an integrated intervention for HIV-positive IDUs, and these data show the acceptability of such an approach.
