RESUMEN

BACKGROUND: Non-disclosure of known HIV status by people living with HIV but undergoing HIV testing leads to waste of HIV testing resources and distortion of estimates of HIV indicators. In Mozambique, an estimated one-third of persons who tested positive already knew their HIV-positive status. To our knowledge, this study is the first to assess the factors that prevent people living with HIV (PLHIV) from disclosing their HIV-positive status to healthcare providers during a provider-initiated counseling and testing (PICT) campaign. METHODS: This analysis was nested in a larger PICT cross-sectional study performed in the Manhiça District, Southern Mozambique from January to July 2019, in which healthcare providers actively asked patients about their HIV-status. Patients who tested positive for HIV were crosschecked with the hospital database to identify those who had previously tested positive and were currently or previously enrolled in care. PLHIV who did not disclose their HIV-positive status were invited to participate and provide consent, and were interviewed using a questionnaire designed to explore barriers, patterns of community/family disclosure, and stigma and discrimination. RESULTS: We found that 16.1% of participants who tested positive during a PICT session already knew their HIV-positive status but did not disclose it to the healthcare provider. All the participants reported previous mistreatment by general healthcare providers as a reason for nondisclosure during PICT. Other reasons included the desire to know if they were cured (33.3%) or to re-engage in care (23.5%). Among respondents, 83.9% reported having disclosed their HIV-status within their close community, 48.1% reported being victims of verbal or physical discrimination following their HIV diagnosis, and 46.7% reported that their HIV status affected their daily activities. CONCLUSION: Previous mistreatment by healthcare workers was the main barrier to disclosing HIV-positive status. The high proportion of those disclosing their HIV status to their community but not to healthcare providers suggests that challenges with patient-provider relationships affect this care behavior rather than social stigma and discrimination. Improving patient-provider relationships could increase trust in healthcare providers, reduce non-disclosures, and help optimize resources and provide accurate estimates of the UNAIDS first 95 goal.

RESUMEN

BACKGROUND: Urogenital Chlamydia trachomatis infection remains prevalent and causes substantial reproductive morbidity. Recent studies have raised concern about the efficacy of azithromycin for the treatment of chlamydia infection. METHODS: We conducted a randomized trial comparing oral azithromycin with doxycycline for the treatment of urogenital chlamydia infection among adolescents in youth correctional facilities, to evaluate the noninferiority of azithromycin (1 g in one dose) to doxycycline (100 mg twice daily for 7 days). The treatment was directly observed. The primary end point was treatment failure at 28 days after treatment initiation, with treatment failure determined on the basis of nucleic acid amplification testing, sexual history, and outer membrane protein A (OmpA) genotyping of C. trachomatis strains. RESULTS: Among the 567 participants enrolled, 284 were randomly assigned to receive azithromycin, and 283 were randomly assigned to receive doxycycline. A total of 155 participants in each treatment group (65% male) made up the per-protocol population. There were no treatment failures in the doxycycline group. In the azithromycin group, treatment failure occurred in 5 participants (3.2%; 95% confidence interval, 0.4 to 7.4%). The observed difference in failure rates between the treatment groups was 3.2 percentage points, with an upper boundary of the 90% confidence interval of 5.9 percentage points, which exceeded the prespecified absolute 5-percentage-point cutoff for establishing the noninferiority of azithromycin. CONCLUSIONS: In the context of a closed population receiving directly observed treatment for urogenital chlamydia infection, the efficacy of azithromycin was 97%, and the efficacy of doxycycline was 100%. The noninferiority of azithromycin was not established in this setting. (Funded by the National Institute of Allergy and Infectious Diseases; ClinicalTrials.gov number, NCT00980148.).

RESUMEN

BACKGROUND: Men who have sex with men (MSM) are at risk for cancers attributable to human papillomavirus (HPV), including oropharyngeal cancer. Human papillomavirus vaccination is recommended for US MSM through age 26 years. Oral HPV infection is associated with oropharyngeal cancer. We determined oral HPV prevalence and risk factors among young MSM. METHODS: The Young Men's HPV study enrolled MSM aged 18 through 26 years from clinics in Chicago and Los Angeles during 2012 to 2014. Participants self-reported demographics, sexual behaviors, vaccination and human immunodeficiency virus (HIV) status. Self-collected oral rinse specimens were tested for HPV DNA (37 types) by L1-consensus PCR. We calculated adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for risk factors associated with oral HPV among participants not previously vaccinated. RESULTS: Oral HPV was detected in 87 (9.4%) of 922; 9-valent vaccine types were detected in 37 (4.0%) of 922. Among HIV-positive participants, 17 (19.3%) of 88 had oral HPV detected. Oral HPV was more prevalent among those reporting first sex at 18 years of age or younger (aPR, 2.44; 95% CI, 1.16-5.12); HIV infection (aPR, 1.99; 95% CI, 1.14-3.48); greater than 5 sex partners within the past month (aPR, 1.93; 95% CI, 1.13-3.31); performing oral sex on greater than 5 partners within the last 3 months (aPR, 1.87; 95% CI, 1.12-3.13); and having greater than 5 male sex partners within the last 3 months (aPR, 1.76; 95% CI, 1.08-2.87). Only 454 (49.2%) of 922 were aware that HPV can cause oropharyngeal cancers. CONCLUSIONS: Many oral HPV infections were with types targeted by vaccination. Oral HPV infections were significantly associated with HIV and sexual behaviors. Fewer than half of participants were aware that HPV could cause oropharyngeal cancer.

RESUMEN

In 2017, rapid human immunodeficiency virus (HIV) testing services enabled the HIV diagnosis and treatment of approximately 15.3 million persons with HIV infection in sub-Saharan Africa with life-saving antiretroviral therapy (ART) (1). Although suboptimal testing practices and misdiagnoses have been reported in sub-Saharan Africa and elsewhere, trends in population burden and rate of false positive HIV diagnosis (false diagnosis) have not been reported (2,3). Understanding the population prevalence and trends of false diagnosis is fundamental for guiding rapid HIV testing policies and practices. To help address this need, CDC analyzed data from 57,655 residents aged 15-59 years in the Chókwè Health and Demographic Surveillance System (CHDSS) in Mozambique to evaluate trends in the rate (the percentage of false diagnoses among retested persons reporting a prior HIV diagnosis) and population prevalence of false diagnosis. From 2014 to 2017, the observed rate of false diagnosis in CHDSS decreased from 0.66% to 0.00% (p<0.001), and the estimated population prevalence of false diagnosis decreased from 0.08% to 0.01% (p = 0.0016). Although the prevalence and rate of false diagnosis are low and have decreased significantly in CHDSS, observed false diagnoses underscore the importance of routine HIV retesting before ART initiation and implementation of comprehensive rapid HIV test quality management systems (2,4,5).

RESUMEN

Prevalence of human papillomavirus (HPV) infections was assessed among 1033 young men who have sex with men (MSM) aged 18-26 years. HPV (any type) was detected in 742 (71.8%) anal specimens and 101 (9.8%) oral specimens. Although HPV was detected in specimens from both anatomical sites in 83 (8.0%) participants, type-specific concordance for at least 1 HPV type was found in only 35 (3.4%) participants. HIV and smoking were associated with higher prevalence at both sites and frequency of concordant types. Coinfections of identical HPV types were rare, suggesting independent infection events and/or different modes of clearance.

RESUMEN

BACKGROUND: Adult film work involves multiple sex partners, unprotected intercourse and frequent oral/rectal contact. Data on sexual networks and sexual behaviors of adult film performers (AFP) are limited. METHODS: From August 2012 to May 2013, AFPs in Los Angeles, CA, seeking care at 2 clinics that provide sexually transmitted infections (STIs) testing to performers were offered urogenital, pharyngeal, and rectal chlamydia/gonorrhea testing. Participants were 18 years or older and performed in at least 1 adult film scene within the past year. A Web-based survey was used to collect sexual behavior information. RESULTS: A total of 360 AFPs were enrolled; 75% (n = 271) were women, and the median age was 25 years (interquartile range, 22-31 years). Most reported a main partner (73%), 23% reported non-film transactional partners, and only 6% reported always using condoms on-set. Overall, 24% (n = 86) tested positive for chlamydia or gonorrhea; 15% for chlamydia (n = 54) and 11% for gonorrhea (n = 41). Prevalence of chlamydia/gonorrhea varied by time as a performer (median, year 2 vs year 3; P = 0.06), and days of adult film-work in the past 30 days (median, 6 days vs 4 days; P = 0.02). In multivariable analyses, age (adjusted odds ratio, 0.90; 95% confidence interval, 0.85-0.96) and type of scene (adjusted odds ratio for double vaginal = 2.89; 95% confidence interval, 1.29-6.48) were associated with chlamydia/gonorrhea positivity. CONCLUSIONS: Adult film performers had a high prevalence of STIs and reported low levels of condom use in the context of most sexual partnerships. Targeted intervention strategies-both in and outside the workplace-are needed to limit the spread of STIs.

RESUMEN

BACKGROUND: Since 2011, in the United States, quadrivalent human papillomavirus (HPV) vaccine has been recommended for boys aged 11 to 12 years, men through age 21, and men who have sex with men (MSM) through age 26. We assessed HPV vaccination coverage and factors associated with vaccination among young MSM (YMSM) and transgender women (TGW) in 2 cities. METHODS: During 2012-2014, 808 YMSM and TGW aged 18 to 26 years reported vaccination status in a self-administered computerized questionnaire at 3 sexually transmitted disease (STD) clinics in Los Angeles and Chicago. Associations with HPV vaccination were assessed using bivariate and multivariable models to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS: Few of the diverse participants (Hispanic/Latino, 38.0%; white, 27.0%; and black/African American, 17.9%) reported receiving 1 or more HPV vaccine doses (n = 111 [13.7%]) and even fewer reported 3 doses (n = 37 [4.6%]). A multivariable model found associations between vaccination and having a 4-year college degree or higher (aOR, 2.83; CI, 1.55-5.17) and self-reported STDs (aOR, 1.21; CI, 1.03-1.42). In a model including recommendation variables, the strongest predictor of vaccination was a health care provider recommendation (aOR, 11.85; CI, 6.70-20.98). CONCLUSIONS: Human papillomavirus vaccination coverage was low among YMSM and TGW in this 2-US city study. Our findings suggest further efforts are needed to reach YMSM seeking care in STD clinics, increase strong recommendations from health care providers, and integrate HPV vaccination with other clinical services such as STD testing.

RESUMEN

BACKGROUND: Gay, bisexual, and other men who have sex with men (MSM) are at high risk for human papillomavirus (HPV) infection; vaccination is recommended for US males, including MSM through age 26 years. We assessed evidence of HPV among vaccine-eligible MSM and transgender women to monitor vaccine impact. METHODS: During 2012-2014, MSM aged 18-26 years at select clinics completed a computer-assisted self-interview regarding sexual behavior, human immunodeficiency virus (HIV) status, and vaccinations. Self-collected anal swab and oral rinse specimens were tested for HPV DNA (37 types) by L1 consensus polymerase chain reaction; serum was tested for HPV antibodies (4 types) by a multiplexed virus-like particle-based immunoglobulin G direct enzyme-linked immunosorbent assay. RESULTS: Among 922 vaccine-eligible participants, the mean age was 23 years, and the mean number of lifetime sex partners was 37. Among 834 without HIV infection, any anal HPV was detected in 69.4% and any oral HPV in 8.4%, yet only 8.5% had evidence of exposure to all quadrivalent vaccine types. In multivariate analysis, HPV prevalence varied significantly (P < .05) by HIV status, sexual orientation, and lifetime number of sex partners, but not by race/ethnicity. DISCUSSIONS: Most young MSM lacked evidence of current or past infection with all vaccine-type HPV types, suggesting that they could benefit from vaccination. The impact of vaccination among MSM may be assessed by monitoring HPV prevalence, including in self-collected specimens.

RESUMEN

BACKGROUND: The US system for gonococcal antimicrobial susceptibility surveillance monitors trends exclusively among men with urethral infection, the population from whom the yield of gonococcal culture is highest. Little is known about the susceptibility of female urogenital isolates, and it is unclear whether gonococcal susceptibility among men who report sex exclusively with women (MSW) is representative of susceptibility among women. METHODS: Using isolates collected during a recent treatment trial in 5 US cities, we performed a secondary analysis to compare antimicrobial susceptibilities of Neisseria gonorrhoeae urogenital isolates obtained from women, MSW, and men who have sex with men (MSM). Pretreatment isolates were collected from trial participants; minimum inhibitory concentrations (MICs) were determined by agar dilution. Geometric mean MICs were adjusted for geographic location using general linear models. RESULTS: Susceptibility data for urogenital isolates from 56 women, 252 MSW, and 170 MSM were studied. The adjusted geometric mean ceftriaxone MIC was similar among women (0.0067 µg/mL; 95% confidence interval [CI], 0.0049-0.0092 µg/mL) and MSW (0.0060 µg/mL; 95% CI, 0.0053-0.0066 µg/mL). In contrast, the adjusted geometric mean ceftriaxone MIC was higher among MSM (0.0098 µg/mL; 95% CI, 0.0082-0.0119 µg/mL) than among MSW. This same pattern was observed for other antimicrobials, including cefixime and azithromycin CONCLUSIONS: Ceftriaxone, cefixime, and azithromycin MICs were higher among MSM than among MSW, but were similar among women and MSW. These findings suggest that gonococcal antimicrobial susceptibility surveillance based on urethral isolates from MSW may adequately represent susceptibility of urogenital N. gonorrhoeae in women.

RESUMEN

OBJECTIVES: We examined perceptions of and attitudes toward existing and potential syphilis interventions, including case management and Web-based programs, to increase syphilis testing among high-risk men who have sex with men (MSM). METHODS: Between October 2010 and June 2011, we conducted in-depth interviews with 19 MSM in Los Angeles, California, with repeat early syphilis infections (primary, secondary, and early latent syphilis) within the previous 5 years. We analyzed the interviews inductively to determine the most acceptable potential interventions. RESULTS: Experiences with health department and community-based standard of care case management were generally positive. The most popular interventions among respondents included a Web site providing information on syphilis and syphilis testing, automated Web reminders to test, being paid to test, free online home testing kits, and preexposure prophylactic medication. Respondents' beliefs that they would continue to practice high-risk sexual behaviors reinforced their reasons for wanting increased accessibility and convenient testing strategies. CONCLUSIONS: Public health officials should consider participant responses to potential interventions for syphilis, which suggest that high-risk MSM would consider testing more often or using other interventions.

RESUMEN

BACKGROUND: A call has recently been made by the public health and medical communities to understand the neighborhood context of a patient's life in order to improve education and treatment. To do this, methods are required that can collect "contextual" characteristics while complementing the spatial analysis of more traditional data. This also needs to happen within a standardized, transferable, easy-to-implement framework. METHODS: The Spatial Video Geonarrative (SVG) is an environmentally-cued narrative where place is used to stimulate discussion about fine-scale geographic characteristics of an area and the context of their occurrence. It is a simple yet powerful approach to enable collection and spatial analysis of expert and resident health-related perceptions and experiences of places. Participants comment about where they live or work while guiding a driver through the area. Four GPS-enabled cameras are attached to the vehicle to capture the places that are observed and discussed by the participant. Audio recording of this narrative is linked to the video via time stamp. A program (G-Code) is then used to geotag each word as a point in a geographic information system (GIS). Querying and density analysis can then be performed on the narrative text to identify spatial patterns within one narrative or across multiple narratives. This approach is illustrated using case studies on post-disaster psychopathology, crime, mosquito control, and TB in homeless populations. RESULTS: SVG can be used to map individual, group, or contested group context for an environment. The method can also gather data for cohorts where traditional spatial data are absent. In addition, SVG provides a means to spatially capture, map and archive institutional knowledge. CONCLUSIONS: SVG GIS output can be used to advance theory by being used as input into qualitative and/or spatial analyses. SVG can also be used to gain near-real time insight therefore supporting applied interventions. Advances over existing geonarrative approaches include the simultaneous collection of video data to visually support any commentary, and the ease-of-application making it a transferable method across different environments and skillsets.

RESUMEN

BACKGROUND: Ceftriaxone is the foundation of currently recommended gonorrhea treatment. There is an urgent need for backup treatment options for patients with cephalosporin allergy or infections due to suspected cephalosporin-resistant Neisseria gonorrhoeae. We evaluated the efficacy and tolerability of 2 combinations of existing noncephalosporin antimicrobials for treatment of patients with urogenital gonorrhea. METHODS: We conducted a randomized, multisite, open-label, noncomparative trial in 5 outpatient sexually transmitted disease clinic sites in Alabama, California, Maryland, and Pennsylvania. Patients aged 15-60 years diagnosed with uncomplicated urogenital gonorrhea were randomly assigned to either gentamicin 240 mg intramuscularly plus azithromycin 2 g orally, or gemifloxacin 320 mg orally plus azithromycin 2 g orally. The primary outcome was microbiological cure of urogenital infections (negative follow-up culture) at 10-17 days after treatment among 401 participants in the per protocol population. RESULTS: Microbiological cure was achieved by 100% (lower 1-sided exact 95% confidence interval [CI] bound, 98.5%) of 202 evaluable participants receiving gentamicin/azithromycin, and 99.5% (lower 1-sided exact 95% CI bound, 97.6%) of 199 evaluable participants receiving gemifloxacin/azithromycin. Gentamicin/azithromycin cured 10 of 10 pharyngeal infections and 1 of 1 rectal infection; gemifloxacin/azithromycin cured 15 of 15 pharyngeal and 5 of 5 rectal infections. Gastrointestinal adverse events were common in both arms. CONCLUSIONS: Gentamicin/azithromycin and gemifloxacin/azithromycin were highly effective for treatment of urogenital gonorrhea. Gastrointestinal adverse events may limit routine use. These non-cephalosporin-based regimens may be useful alternative options for patients who cannot be treated with cephalosporin antimicrobials. Additional treatment options for gonorrhea are needed. Clinical Trials Registration. NCT00926796.

RESUMEN

BACKGROUND: In 2007, the Los Angeles County Department of Public Health launched Check Yourself, a new social marketing campaign, as part of ongoing efforts to address the persistent syphilis epidemic among men who have sex with men (MSM) in the county. The goals of the campaign were to increase syphilis testing and knowledge among MSM. Check Yourself was planned with careful attention to the principles of social marketing, including formative research, market segmentation, and an emphasis on building a strong brand. METHODS: A cross-sectional survey using a time-location sample was conducted in 2009 for the evaluation. The survey assessed demographics, syphilis knowledge, and recent syphilis testing as well as unaided awareness, aided awareness, and confirmed awareness, meaning that a person had both awareness of the campaign and could correctly identify that the campaign was about syphilis. The total sample size was 306. RESULTS: Unaided awareness for Check Yourself was 20.7%, and aided awareness was 67.5%, bringing total campaign awareness to 88.2%; confirmed awareness was 30.4%. Unaided campaign awareness was associated with syphilis knowledge and important risk behaviors for syphilis, indicating that the campaign reached an appropriate audience. Total awareness was not associated with recent syphilis testing in a multivariate model. However, MSM with confirmed awareness were more than 6 times more likely to have been recently tested. CONCLUSIONS: The evaluation of Check Yourself found that the campaign had a very strong brand among MSM. Although total awareness was not associated with syphilis testing, confirmed awareness, a more robust measure, was strongly associated.

RESUMEN

In response to high chlamydia and gonorrhea morbidity, particularly among young African American and Latina women, the Los Angeles County Department of Public Health launched a free home testing program for Chlamydia trachomatis and Neisseria gonorrhoeae. The primary objectives were to increase chlamydia and gonorrhea testing by removing key barriers and to motivate young women to screen routinely for these sexually transmitted diseases (STDs). The program was promoted with a social marketing campaign urging women to order home collection kits online or by telephone. In the program's first year, 2927 kits were ordered and 1543 testable specimens returned; 131 women (8.5%) had a positive test result. The strong response, high morbidity, and program scalability indicated strong potential as a new tool for STD control.

RESUMEN

To determine if a structural intervention of providing one condom a week to inmates in the Los Angeles County Men's Central Jail MSM unit reduces HIV transmissions and net social cost, we estimated numbers of new HIV infections (1) when condoms are available; and (2) when they are not. Input data came from a 2007 survey of inmates, the literature and intervention program records. Base case estimates showed that condom distribution averted 1/4 of HIV transmissions. We predict .8 new infections monthly among 69 HIV-negative, sexually active inmates without condom distribution, but .6 new infections with condom availability. The discounted future medical costs averted due to fewer HIV transmissions exceed program costs, so condom distribution in jail reduces total costs. Cost savings were sensitive to the proportion of anal sex acts protected by condoms, thus allowing inmates more than one condom per week could potentially increase the program's effectiveness.

RESUMEN

BACKGROUND/OBJECTIVES: We evaluated the effectiveness of a Community-Embedded Disease Intervention Specialist (CEDIS) in providing partner notification (PN) for primary syphilis cases in a high STD morbidity, community-based clinic serving men who have sex with men in Los Angeles. METHODS: The CEDIS was trained by the same standards as the local health department Disease Investigator Specialists but was employed by and stationed at the clinic where the primary cases were diagnosed. We compared the CEDIS on specific PN outcomes before and after placement of the CEDIS and among countywide men who have sex with men primary syphilis cases, excluding the cases from the CEDIS clinic. RESULTS: In 2009-2010 after placement of the CEDIS, 100% (87) of primary cases assigned were interviewed; 28% (26) on the same day as their clinic visit and 64% (59) within 7 days. In 2006-2007 before placement of the CEDIS, 67% (43) of primary cases assigned were interviewed; only 2% (1) were interviewed within 7 days. In 2009-2010 countywide, 9% (21) of 252 primary cases assigned were interviewed on the same day as their clinic visit; 18% (45) within 7 days. After placement of the CEDIS, 15% (21) of 140 partners elicited were identified with early syphilis and brought to treatment compared with 0% of 13 partners elicited before placement of the CEDIS, and 15% (25) of 171 partners elicited countywide. CONCLUSION: The CEDIS program fosters key elements to a successful PN program, such as prompt interviewing of newly diagnosed cases and community trust.

RESUMEN

BACKGROUND: Undiagnosed sexually transmitted infections (STIs) may be common in the adult film industry because performers frequently engage in unprotected oral and anal intercourse, STIs are often asymptomatic, and the industry relies on urine-based testing. METHODS: Between mid-May and mid-September 2010, a consecutive sample of adult film industry performers recruited from a clinic in Los Angeles, California, that provides medical care to performers was offered oropharyngeal, rectal, and urogenital testing for Gonorrhea, and rectal and urogenital testing for Chlamydia. RESULTS: During the 4-month study period, 168 participants were enrolled: 112 (67%) were female and 56 (33%) were male. Of the 47 (28%) who tested positive for Gonorrhea and/or Chlamydia, 11 (23%) cases would not have been detected through urogenital testing alone. Gonorrhea was the most common STI (42/168; 25%) and the oropharynx the most common site of infection (37/47; 79%). Thirty-five (95%) oropharyngeal and 21 (91%) rectal infections were asymptomatic. Few participants reported using condoms consistently while performing or with their personal sex partners. CONCLUSIONS: Adult film industry performers had a high burden of STIs. Undiagnosed asymptomatic rectal and oropharyngeal STIs were common and are likely reservoirs for transmission to sexual partners inside and outside the workplace. Performers should be tested at all anatomical sites irrespective of symptoms, and condom use should be enforced to protect workers in this industry.

RESUMEN

BACKGROUND: This article presents an evaluation of inSPOTLA.org, a sexually transmitted disease partner notification Web site in Los Angeles County primarily targeting men who have sex with men (MSM). Since its launch in 2005, this Web site has received more than 400,000 visitors and resulted in nearly 50,000 e-mail postcards sent. However, there have been limited quantitative data concerning use of the service for actual partner notification. This study investigated awareness and use of inSPOTLA among MSM, as well as the effect of an advertising campaign. METHODS: Data from 2 cross-sectional surveys using time-location samples were used for the evaluation, with a baseline survey conducted in 2007 and a follow-up conducted in 2009. The advertising campaign was implemented between the surveys in 2008. RESULTS: Awareness of inSPOTLA was 15.8% in the baseline survey and 14.4% in the follow-up survey, with no statistically significant difference. Reported use of inSPOTLA for partner notification was less than 2% in both surveys, again with no significant difference. In addition to the surveys, a high-volume sexual health clinic that serves the MSM population in Los Angeles collected data on reason for visit, including referrals from inSPOTLA, from all patients from 2007 through 2009. In 3 years, 2 individuals stated having received an inSPOTLA e-card as the reason for their visit. CONCLUSIONS: While website user statistics seemed to indicate an impressive level of use, our evaluation of inSPOTLA found very limited evidence of program effectiveness for the purpose of actual partner notification among MSM in Los Angeles County.

RESUMEN

OBJECTIVES: We examined rates of and risk factors for repeat syphilis infection among men who have sex with men (MSM) in California. METHODS: We analyzed 2002 to 2006 California syphilis surveillance system data. RESULTS: During the study period, a mean of 5.9% (range: 4.9%-7.1% per year) of MSM had a repeat primary or secondary (PS) syphilis infection within 2 years of an initial infection. There was no significant increase in the annual proportion of MSM with a repeat syphilis infection (P = .42). In a multivariable model, factors associated with repeat syphilis infection were HIV infection (odds ratio [OR] = 1.65; 95% confidence interval [CI] = 1.14, 2.37), Black race (OR = 1.84; 95% CI = 1.12, 3.04), and 10 or more recent sex partners (OR = 1.99; 95% CI = 1.12, 3.50). CONCLUSIONS: Approximately 6% of MSM in California have a repeat PS syphilis infection within 2 years of an initial infection. HIV infection, Black race, and having multiple sex partners are associated with increased odds of repeat infection. Syphilis elimination efforts should include messages about the risk for repeat infection and the importance of follow-up testing. Public health attention to individuals repeatedly infected with syphilis may help reduce local disease burdens.
