A comparison between audio computer-assisted self-interviews and clinician interviews for obtaining the sexual history.

Objective: The objective of this study was to compare reporting between audio computer-assisted self-interview (ACASI) and clinician-administered sexual histories. Goal: The goal of this study was to explore the usefulness of ACASI in sexually transmitted disease (STD) clinics. Study: The authors conducted a cross-sectional study of ACASI followed by a clinician history (CH) among 609 patients (52% male, 59% white) in an urban, public STD clinic. We assessed completeness of data, item prevalence, and report concordance for sexual history and patient characteristic variables classified as socially neutral (n = 5), sensitive (n = 11), or rewarded (n = 4). Results: Women more often reported by ACASI than during CH same-sex behavior (19.6% vs. 11.5%), oral sex (67.3% vs. 50.0%), transactional sex (20.7% vs. 9.8%), and amphetamine use (4.9% vs. 0.7%) but were less likely to report STD symptoms (55.4% vs. 63.7%; all McNemar chi-squared P values <0.003). Men’s reporting was similar between interviews, except for ever having had sex with another man (36.9% ACASI vs. 28.7% CH, P <0.001). Reporting agreement as measured by kappas and intraclass correlation coefficients was only moderate for socially sensitive and rewarded variables but was substantial or almost perfect for socially neutral variables. ACASI data tended to be more complete. ACASI was acceptable to 89% of participants. Conclusions: ACASI sexual histories may help to identify persons at risk for STDs.

Hiv Serosorting in Men Who Have Sex With Men: Is It Safe?

Background:Serosorting is the practice of preferentially having sex with partners of concordant HIV status or of selectively using condoms with HIV-discordant partners. Methods:We evaluated the epidemiology of serosorting among men who have sex with men (MSM) seen in a sexually transmitted disease clinic, Seattle, WA, 2001-2007, and defined the percentage of visits during which MSM tested HIV positive based on whether they reported nonconcordant unprotected anal intercourse (UAI), UAI only with partners thought to be HIV negative (serosorters), no UAI, or no anal intercourse. Results:Men reported serosorting during 3295 (26%) of 12,449 visits. From 2001 to 2007, the proportion of visits during which men reported serosorting increased (P = 0.02); this change was greater among HIV-infected MSM than among HIV-uninfected MSM. Among men who tested HIV negative in the preceding year, HIV tests were positive in 49 (3.5%) of 1386 who reported nonconcordant UAI, 40 (2.6%) of 1526 serosorters, 28 (1.5%) of 1827 who had only protected anal intercourse, and 0 of 410 who had no anal intercourse (P < 0.0001); 32% of new HIV infections occurred in serosorters. The prevalence of HIV was higher among serosorters tested during 2004-2007 than among those tested during 2001-2003 (0.85% vs. 3.2%, P = 0.03). Conclusions:Serosorting offers MSM limited protection from HIV.

Partner notification for HIV and STD in the United States: low coverage for gonorrhea, chlamydial infection, and HIV.

Background Little is known about the scope of current public health partner-notification (PN) activities in the United States. Goal The goal of the study was to define what PN services U.S. health departments provide in areas with high STD/HIV-related morbidity. Study Design The study involved a survey of STD program staff members in U.S. areas with the highest reported rates of infectious syphilis, gonorrhea, chlamydia, and HIV in 1998. Results Staff members of 60 (77%) of 78 health departments provided data. PN interviews were conducted with 7583 (89%) of 8492 cases of syphilis, 23,097 (17%) of 139,287 cases of gonorrhea, and 26,487 (12%) of 228,210 cases of chlamydia. In areas with mandatory HIV reporting, 4375 (52%) of 8328 persons infected with HIV were interviewed for PN. Conclusions Except for patients with syphilis, public health PN services affect only a minority of persons with STD or HIV infection in high-morbidity areas of the United States.

Standard Treatment Regimens for Nongonococcal Urethritis Have Similar but Declining Cure Rates: A Randomized Controlled Trial

BACKGROUND Azithromycin or doxycycline is recommended for nongonococcal urethritis (NGU); recent evidence suggests their efficacy has declined. We compared azithromycin and doxycycline in men with NGU, hypothesizing that azithromycin was more effective than doxycycline. METHODS From January 2007 to July 2011, English-speaking males ≥16 years, attending a sexually transmitted diseases clinic in Seattle, Washington, with NGU (visible urethral discharge or ≥5 polymorphonuclear leukocytes per high-power field [PMNs/HPF]) were eligible for this double-blind, parallel-group superiority trial. Participants received active azithromycin (1 g) + placebo doxycycline or active doxycycline (100 mg twice daily for 7 days) + placebo azithromycin. Urine was tested for Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), Ureaplasma urealyticum biovar 2 (UU-2), and Trichomonas vaginalis (TV) using nucleic acid amplification tests. Clinical cure (<5 PMNs/HPF with or without urethral symptoms and absence of discharge) and microbiologic cure (negative tests for CT, MG, and/or UU-2) were determined after 3 weeks. RESULTS Of 606 men, 304 were randomized to azithromycin and 302 to doxycycline; CT, MG, TV, and UU-2 were detected in 24%, 13%, 2%, and 23%, respectively. In modified intent-to-treat analyses, 172 of 216 (80%; 95% confidence interval [CI], 74%-85%) receiving azithromycin and 157 of 206 (76%; 95% CI, 70%-82%) receiving doxycycline experienced clinical cure (P = .40). In pathogen-specific analyses, clinical cure did not differ by arm, nor did microbiologic cure differ for CT (86% vs 90%, P = .56), MG (40% vs 30%, P = .41), or UU-2 (75% vs 70%, P = .50). No unexpected adverse events occurred. CONCLUSIONS Clinical and microbiologic cure rates for NGU were somewhat low and there was no significant difference between azithromycin and doxycycline. Mycoplasma genitalium treatment failure was extremely common. Clinical Trials Registration.NCT00358462.

Prediction of HIV acquisition among men who have sex with men.

Objective: To develop and validate an easy-to-use prediction model for HIV acquisition among men who have sex with men (MSM). Methods: We developed prediction models using medical records data from an STD clinic (2001–2008) and validated these models using data from the control arm of Project Explore, an HIV prevention trial (1999–2003). Results: Of 1903 MSM who tested for HIV more than once in the development sample, 101 acquired HIV over 6.7 years of follow-up. Annual HIV incidence was 2.57% (95% confidence interval [CI]: 2.09%, 3.12%). During 4 years of follow-up of 2081 Project Explore control arm participants, 144 acquired HIV for an incidence of 2.32% (95% CI: 1.96%, 2.73%). A prediction model that included variables indicating use of methamphetamine or inhaled nitrites in the prior 6 months, unprotected anal intercourse with a partner of positive or unknown HIV status in the prior year, ≥10 male sex partners in the prior year, and current diagnosis or history of bacterial sexually transmitted infection was well calibrated overall (expected-observed ratio = 1.01; 95% CI: 0.97, 1.05) and had modest discriminatory accuracy at 1 year (area under the receiver-operator characteristic curve = 0.67; 95% CI: 0.60, 0.75) and at 4 years (area under the receiver-operator characteristic curve = 0.66; 95% CI: 0.61, 0.71). Over 4 years, cumulative incidence ranged from 3.9% to 14.3% for groups of men defined by the prediction model. Conclusions: A new risk score was predictive of HIV acquisition and could assist providers in counseling MSM and in targeting intensified prevention to MSM at greatest risk for HIV infection. Its accuracy requires further evaluation.

Persistence of racial differences in attitudes toward homosexuality in the United States.

Background:Stigma may mediate some of the observed disparity in HIV infection rates between black and white men who have sex with men (MSM). Methods:We used data from the General Social Survey to describe race-specific trends in the US populations attitude toward homosexuality, reporting of male same-sex sexual behavior, and behaviors that might mediate the relationship between stigma and HIV transmission among MSM. Results:The proportion of blacks who indicated that homosexuality was “always wrong” was 72.3% in 2008, largely unchanged since the 1970s. In contrast, among white respondents, this figure declined from 70.8% in 1973 to 51.6% in 2008 with most change occurring since the early 1990s. Participants who knew a gay person were less likely to have negative attitudes toward homosexuality (relative risk, 0.60; 95% confidence interval, 0.52 to 0.69). Among MSM, twice as many black MSM reported that homosexuality is “always wrong” compared with white MSM (57.1% versus 26.8%, P = 0.003). MSM with unfavorable attitudes toward homosexuality were less likely to report ever testing for HIV compared with MSM with more favorable attitudes (relative risk, 0.50; 95% confidence interval, 0.31 to 0.78). Conclusions:US attitudes toward homosexuality are characterized by persistent racial differences, which may help explain disparities in HIV infection rates between black and white MSM.

Targeted screening for primary HIV infection through pooled HIV-RNA testing in men who have sex with men

HIV-RNA testing may identify individuals with primary HIV infection. Men who have sex with men (MSM) having HIV testing through Public Health, Seattle and King County were screened for primary infection through pooled RNA testing. Eighty-one out of 3525 specimens (2.3%) had detectable antibody and RNA, and seven out of 3439 antibody-negative specimens (0.2%) had HIV RNA. Targeted screening for primary infection through pooled RNA testing in MSM is a useful addition to HIV case finding.

Don’t ask, don’t tell: patterns of HIV disclosure among HIV positive men who have sex with men with recent STI practising high risk behaviour in Los Angeles and Seattle

Objectives: A high incidence of HIV continues among men who have sex with men (MSM) in industrialised nations and research indicates many MSM do not disclose their HIV status to sex partners. Themes as to why MSM attending sexually transmitted infection (STI) clinics in Los Angeles and Seattle do and do not disclose their HIV status are identified. Methods: 55 HIV positive MSM (24 in Seattle, 31 in Los Angeles) reporting recent STI or unprotected anal intercourse with a serostatus negative or unknown partner from STI clinics underwent in-depth interviews about their disclosure practices that were tape recorded, transcribed verbatim, coded, and content analysed. Results: HIV disclosure themes fell into a continuum from unlikely to likely. Themes for “unlikely to disclose” were HIV is “nobody’s business,” being in denial, having a low viral load, fear of rejection, “it’s just sex,” using drugs, and sex in public places. Themes for “possible disclosure” were type of sex practised and partners asking/disclosing first. Themes for “likely to disclose” were feelings for partner, feeling responsible for partner’s health, and fearing arrest. Many reported non-verbal disclosure methods. Some thought partners should ask for HIV status; many assumed if not asked then their partner must be positive. Conclusions: HIV positive MSM’s decision to disclose their HIV status to sex partners is complex, and is influenced by a sense of responsibility to partners, acceptance of being HIV positive, the perceived transmission risk, and the context and meaning of sex. Efforts to promote disclosure will need to address these complex issues.

Mycoplasma genitalium: Should We Treat and How?

Mycoplasma genitalium is associated with acute and chronic urethritis in men. Existing data on infection in women are limited and inconsistent but suggest that M. genitalium is associated with urethritis, cervicitis, pelvic inflammatory disease, and possibly female infertility. Data are inconclusive regarding the role of M. genitalium in adverse pregnancy outcomes and ectopic pregnancy. Available data suggest that azithromycin is superior to doxycycline in treating M. genitalium infection. However, azithromycin-resistant infections have been reported in 3 continents, and the proportion of azithromycin-resistant M. genitalium infection is unknown. Moxifloxacin is the only drug that currently seems to uniformly eradicate M. genitalium. Detection of M. genitalium is hampered by the absence of a commercially available diagnostic test. Persons with persistent pelvic inflammatory disease or clinically significant persistent urethritis or cervicitis should be tested for M. genitalium, if possible. Infected persons who have not previously received azithromycin should receive that drug. Persons in whom azithromycin therapy fails should be treated with moxifloxicin.

Unsafe sexual behavior and correlates of risk in a probability sample of men who have sex with men in the era of highly active antiretroviral therapy.

Objective: To assess the levels and correlates of potential exposure to and transmission of HIV in a contemporary, community-based probability sample of men who have sex with men (MSM). Methods: In 2003, 311 sexually active MSM participated in a random-digit dial telephone survey in Seattle neighborhoods with a high prevalence of MSM. The primary outcomes were potential exposure to and transmission of HIV, defined as unprotected anal intercourse with a man of opposite or unknown HIV status in the preceding 12 months. Results: Fourteen percent of respondents reported being HIV-positive, 77% reported being HIV-negative, and 8% had not been tested. Of 241 HIV-negative MSM, 25 (10%; 95% confidence interval [CI], 7–15%) were potentially exposed to HIV; among 45 HIV-positive MSM, 14 (31%; 95% CI, 20–46%) were potential HIV-transmitters. Among HIV-negative men, the strongest bivariate correlates of potential exposure to HIV were recent bacterial sexually transmitted disease (odds ratio [OR], 5.8), number of recent male sexual partners (OR, 1.01 per partner), recent sex at a bathhouse (OR, 9.1), and recent use of sildenafil (OR, 4.4), amyl nitrite (OR, 6.2), and methamphetamine (OR, 8.0). Among HIV-infected men, the strongest correlates of potential HIV transmission were recent use of amyl nitrite (OR, 3.1), number of recent male sex partners (OR, 1.07 per partner), and having a male spouse or domestic partner (OR, 0.3). Conclusions: Most MSM knew their HIV status and adopted safer sexual behaviors to reduce their risk of HIV acquisition or transmission. However, 10% of HIV-negative MSM and 31% of HIV-positive MSM recently engaged in behaviors that placed them at high risk for acquiring or transmitting HIV.
