Bacterial Sexually Transmitted Infections Among HIV-Infected Patients in the United States: Estimates From the Medical Monitoring Project

imageBackground: 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. 04/01/2015 01:00 AM
 

Concurrent Sexual Partnerships Among Young Heterosexual Adults at Increased HIV Risk: Types and Characteristics

imageBackground: The impact of concurrency on sexually transmitted infection transmission depends on coital frequency, condom use, duration of relationship overlap, and number of partners. Previous research has identified distinct concurrency types; however, little is known about their risk characteristics. Methods: Men (n = 261) and women (n = 275) aged 18 to 30 years at increased risk for acquiring HIV were recruited from community locations in Los Angeles. Participants completed 4 in-person interviews for 12 months. Partnership data were used to characterize the prevalence of 4 types of concurrency: transitional (2 overlapping relationships in which the first relationship ended before the second), single day (a second relationship of 1 day’s duration during the course of another relationship), contained (a second relationship >1 day began and ended during the course of another), and multiple (≥3 overlapping relationships). Multilevel random intercept models were used to estimate mean coital frequency, proportion of condom-protected acts, total duration of overlap, and lifetime sex partners. Results: At baseline, 47% of male and 32% of female participants reported any type of concurrency in the previous 4 months, and 26% of men and 10% of women reported multiple concurrencies. Condom use ranged from 56% to 64%, with the highest use in transitional concurrency (61% for men, 68% for women) and the lowest in contained (52% for men, 54% for women). Coital frequency, total overlap, and lifetime sex partners also varied by concurrency type. Conclusions: Inconsistent condom use and repeated opportunities for exposure characterize common types of concurrency among high-risk young adults. 04/01/2015 01:00 AM
 

Community-Based Sexually Transmitted Infection Screening and Increased Detection of Pharyngeal and Urogenital Chlamydia trachomatis and Neisseria gonorrhoeae Infections in Female Sex Workers in Hong Kong

imageBackground: Female sex workers (FSWs) are vulnerable to sexually transmitted infections (STIs) and are one of the key populations being infected most by Chlamydia trachomatis and Neisseria gonorrhoeae infections. In Hong Kong, limited data on the burden of chlamydial and gonococcal infections exist because regular screenings are not offered. This study aimed to investigate the prevalence of C. trachomatis and N. gonorrhoeae in FSWs and to assess predictors associated with unprotected fellatio. Methods: A cross-sectional study was conduct on 340 FSWs attending a community organization for HIV/STI screening, and a questionnaire addressing sociodemographic and behavioral characteristics was administered to all FSWs. Results: The prevalence of syphilis infection was 2.1%, and none was tested positive for HIV. The positivity for pharyngeal C. trachomatis and N. gonorrhoeae was 3.2% and 4.4%, respectively, whereas that for urogenital chlamydial and gonococcal infection was 10.6% and 0.9%, respectively. Of 313 FSWs offering fellatio, having unprotected fellatio with clients was significantly associated with the perceived low risk of contracting STI via fellatio (adjusted odds ratio [OR], 1.88), working in clubs (adjusted OR, 11.14), working on streets (adjusted OR, 3.28), recently started working in the sex industry for 1 year or less (adjusted OR, 3.05), and reporting group sex in the previous year (adjusted OR, 11.03). Conclusions: The prevalence of HIV and syphilis infection remains low. This study reveals a relatively high prevalence of N. gonorrhoeae detected mostly in the pharynx. Offering pharyngeal screening for STI would facilitate early diagnosis and treatment of gonococcal infection in FSWs in Hong Kong. 04/01/2015 01:00 AM
 

Identifying Psychosocial and Social Correlates of Sexually Transmitted Diseases Among Black Female Teenagers

imageBackground: Black teenagers have relatively high rates of sexually transmitted diseases (STDs), and recent research suggests the role of contextual factors, as well as risk behaviors. We explore the role of 4 categories of risk and protective factors on having a biologically confirmed STD among black, female teenagers. Methods: Black teenage girls (14–19 years old) accessing services at a publicly funded family planning clinic provided a urine specimen for STD testing and completed an audio computer-assisted self-interview that assessed the following: risk behaviors, relationship characteristics, social factors, and psychosocial factors. We examined bivariate associations between each risk and protective factor and having gonorrhea and/or chlamydia, as well as multivariate logistic regression among 339 black female teenagers. Results: More than one-fourth (26.5%) of participants had either gonorrhea and/or chlamydia. In multivariate analyses, having initiated sex before age 15 (adjusted odds ratio [aOR], 1.87) and having concurrent sex partners in the past 6 months (aOR, 1.55) were positively associated with having an STD. Living with her father (aOR, 0.44), believing that an STD is the worst thing that could happen (aOR, 0.50), and believing she would feel dirty and embarrassed about an STD (aOR, 0.44) were negatively associated with having an STD. Conclusions: Social factors and attitudes toward STDs and select risk behaviors were associated with the risk for STDs, suggesting the need for interventions that address more distal factors. Future studies should investigate how such factors influence safer sexual behaviors and the risk for STDs among black female teenagers. 04/01/2015 01:00 AM
 

Sociodemographic and Behavioral Correlates of Anogenital Warts and Human Papillomavirus-Related Knowledge Among Men Who Have Sex With Men and Transwomen in Lima, Peru

imageBackground: Human papilloma virus (HPV) is the most common sexually transmitted infection (STI) globally, with a high burden of anogenital warts (AGW) among men who have sex with men (MSM) and transwomen (TW). Methods: Six-hundred HIV negative MSM and TW (300 with AGW, 300 without) were recruited for a prospective cohort study to examine HPV outcomes and HPV vaccine knowledge. Participants completed a self-administered online questionnaire. Logistic regression was used to assess the association between sociodemographic and behavioral characteristics with HPV vaccine knowledge. Results: The average participant age was 25.5 years. Most (67%) were single and 41.2% self-reported STI symptoms. The average age of first anal intercourse was 17 years, with self-reported sexual role as active (36%), passive (36%), and both (27%). Three quarters (77%) of participants reported engaging in condomless anal or oral sex up to six months prior to the study. Less than half (48%) of participants had heard of HPV. Participants with AGW were more likely to report that condoms helped prevent HPV (p=0.01) and that the absence of genital warts does not mean the absence of HPV (p < 0.01). Conclusion: Study participants had low levels of HPV knowledge but likely high HPV exposure due to condomless anal sex. The HPV knowledge gap may be explained in part by the stigma of sex work, underreporting of STIs, the high cost of the HPV vaccine in Peru, and misinformation about HPV vaccine. More work is needed to educate MSM and TW on HPV and the HPV vaccine. 04/01/2015 01:00 AM
 

Factors Associated With Visible Anogenital Warts Among HIV-Uninfected Peruvian Men Who Have Sex With Men and Transwomen: A Cross-Sectional Study

imageBackground: Visible, anogenital warts may be associated with risk factors for HIV infection. This cross-sectional study examined the factors associated with visible anogenital warts among HIV-uninfected Peruvian men who have sex with men (MSM) and transwomen. Methods: Six hundred HIV-uninfected MSM and transwomen were recruited from a community-based setting in metropolitan Lima, Peru, through outreach activities. Participants were tested for syphilis, completed a behavioral questionnaire, and were examined for visible anogenital warts. Logistic regression was used to assess the independent association between sample characteristics, HIV-related risk factors, and visible anogenital warts. Results: A tertiary education versus a primary/secondary (adjusted odds ratio [AOR], 1.79; 95% confidence interval [CI], 1.07–2.99), a first experience of anal intercourse at age 20 years or older versus younger ages (AOR, 2.80; 95% CI, 1.45–5.38), and self-reporting of current sexually transmitted infection symptoms (AOR, 2.38; 95% CI, 1.61–3.52) were significant correlates of visible anogenital warts, whereas syphilis infection, transactional sex, receptive anal intercourse, and self-identifying as a transwoman were not. Conclusions: Although not associated with key risk factors for HIV infection in Peruvian MSM and transwomen, the presence of visible anogenital warts should prompt clinicians to consider the possibility of unreported same-sex sexual behaviors and other risk sexually transmitted infection/HIV risk factors. 04/01/2015 01:00 AM
