RESUMO
BACKGROUND: Black older-teenaged women have disproportionately high rates of sexually transmitted infections (STI) and unintended pregnancy (UTP). Internet-based interventions can be delivered to large groups of people in a relatively inexpensive manner. In this randomized trial, we examine the efficacy of an evidence-based STI/UTP prevention intervention adapted for older teens and for Internet delivery. METHODS: Black women aged 18-19 years who were not pregnant/seeking to become pregnant were enrolled (n = 637) and randomized to an 8-session intervention or attention control and were followed up at 6/12 months postintervention. The primary outcome was defined as uptake of reliable contraceptives. Other secondary outcomes were examined, including intention to use condoms, intention to use reliable contraception, and STI or pregnancy rates. RESULTS: Overall, at baseline, reliable contraception was 54.8% and dual protection was 29.4%, and the prevalence of STI was 11.1%. Participants were similar by arm for most factors considered. Participation and follow-up rates were excellent (60.9% and 80.3%). There was no statistically significant difference in uptake of reliable contraception for intervention versus controls at 6 months (1.45 [0.99-2.12]) or 12 months (1.33 [0.92-1.91]). At 6 months, several secondary outcomes were improved/trended toward improvement in intervention compared with control, but this effect waned by 12 months, except for intention to use condoms which remained improved. CONCLUSION AND RELEVANCE: The intervention was efficacious for increasing some self-reported UTP and STI prevention behaviors, which waned over time, and the intervention had minimal impact on STI or pregnancy rates suggesting that this type of online intervention may need additional components.

BACKGROUND: We assessed the cost-effectiveness of the Check It program, a novel community-based chlamydia screening and expedited partner treatment program for young Black men conducted in New Orleans since 2017. METHODS: We implemented a probabilistic cost-effectiveness model using a synthetic cohort of 16 181 men and 13 419 women intended to simulate the size of the Black, sexually active population in New Orleans ages 15-24 years. RESULTS: The Check It program cost $196 838 (95% confidence interval [CI]: $117 320-$287 555) to implement, saved 10.2 quality-adjusted life-years (QALYs; 95% CI: 7.7-12.7 QALYs), and saved $140 950 (95% CI: -$197 018 to -$105 620) in medical costs per year. The program cost $5468 (95% CI: cost saving, $16 717) per QALY gained. All iterations of the probabilistic model returned cost-effectiveness ratios less than $50 000 per QALY gained. CONCLUSIONS: The Check It program (a bundled seek, test, and treat chlamydia prevention program for young Black men) is cost-effective under base case assumptions. Communities where Chlamydia trachomatis rates have not declined could consider implementing a similar program.

OBJECTIVES: This study aimed to estimate the impact of the Check It program, a novel community-based chlamydia seek, test, and treat program for young Black men who have sex with women, on test positivity rates for chlamydia in young Black women. METHODS: We used a synthetic control model to compare chlamydia test positivity rates in Orleans Parish (intervention site) with other similar parishes (control sites) in Louisiana. We estimated a model that used all other parishes as potential contributors to a synthetic control for Louisiana as well as a sample limited to the 40 parishes in Louisiana with the largest Black populations. RESULTS: The Check It program was associated with a 1.69-percentage-point decline in chlamydia positivity in the first full year of operation and a 2.44-percentage-point decline in chlamydia positivity in the second full year of operation compared with control sites with the largest Black populations (P = 0.05). Results were similar when the treatment site was compared with all other sites in Louisiana. CONCLUSIONS: The Check It program was associated with a significant decline in chlamydia testing positivity rates among women in Orleans Parish compared with control sites. Screening of young Black men who have sex with women can decrease rates in women living in the same community. Future recommendations for chlamydia screening of young men should be considered.

BACKGROUND: In a randomized controlled trial of 2 g (single-dose) metronidazole (MTZ) versus 500 mg twice daily for 7 days (multidose) for Trichomonas vaginalis treatment, multidose was superior. We examined if the effect was similar by select clinical factors to determine if treatment recommendations could be targeted. METHODS: The primary outcome was T. vaginalis repeat infection at test-of-cure (TOC) 4 weeks after completion of therapy. Analyses were stratified by T. vaginalis history, baseline genital symptoms, and concurrent diagnosis of bacterial vaginosis (BV) per Nugent score at baseline. RESULTS: Women who returned for TOC (n = 540) were included. At baseline, 52.9% had a self-reported history of T. vaginalis; 79.3%, genital symptoms; 5.8%, a gonorrhea diagnosis; and 47.5%, BV. During follow-up, 97.4% took all MTZ as instructed and 34.5% had interval condomless sex with a baseline partner. At TOC, 14.8% tested positive for T. vaginalis. In stratified analysis, women randomized to single-dose MTZ had a higher rate of TOC T. vaginalis positivity than those randomized to multidose if they were symptomatic at baseline (21.4% vs. 10.8%, P = 0.003) or had a reported history of T. vaginalis (24.1% vs. 12.6%, P = 0.01). Test-of-cure T. vaginalis positivity was higher for women receiving a single dose (18.9%) versus multidose (10.8%), irrespective of baseline BV status (P > 0.06). In multivariable analysis, only a history of T. vaginalis and single-dose MTZ were independently associated with a positive TOC for T. vaginalis. CONCLUSIONS: Although multidose MTZ is recommended for all women with T. vaginalis, it is especially important for women with a T. vaginalis history and, given high posttreatment infection rates, a TOC should be performed.

BACKGROUND: Check It is a novel, bundled, community-based seek, test, and treat Chlamydia trachomatis (Ct) screening program for 15- to 24-year-old Black men in New Orleans who have sex with women. The program design addressed barriers and facilitators to Ct screening/treatment by enlisting trusted community partners, incorporating participant input, providing free index/partner expedited treatment, developing relatable marketing materials and an educational Web site, encouraging peer referral, and providing a modest monetary incentive. METHODS: Areas of high poverty were identified using census data; ethnographic/key informant interviews identified sites in those areas where the target population congregated. Black youth informed Web site design and social marketing. Content was inspirational/educational/amusing and endorsed recruitment and brand awareness. A community advisory board, participant interviews, community partner feedback, and recruitment staff involvement in the process evaluation helped refine the program in an ongoing manner. RESULTS: During formative stages, 41 key informant/community advisory board members informed program refinement. Community partners provided venue locations (n = 65) and participant referrals. Between May 22, 2017, and February 28, 2020, 1890 men were enrolled (acceptance rate, 96.0%) with Ct infection rate of 10.2%. Overall study treatment was provided to 86.1% (71.4%-90.9%) of participants who tested positive and 28.5% (14.5%-41.5%) of their partners. Findings from in-depth interviews with participants (n = 43) led to increased treatment uptake. CONCLUSIONS: C. trachomatis community screening of young Black men was successful through collaboration with trusted community partners, by tailoring implements/marketing with participant input, reducing barriers to treatment, and providing modest monetary incentives. The Check It program can serve as a roadmap for reducing health disparities in this population.

Patterns and correlates of substance use among urban African American young women (ages 18-19, n = 459) were examined. Four patterns were identified: no/infrequent alcohol and marijuana use (64.9%); recent alcohol only use (18.2%); recent marijuana only use (7.9%); and recent alcohol and marijuana use (9.0%). Having a recent male sexual partner and a history of sexual coercion were associated with increased odds of marijuana-only and dual use. Greater family support and childhood sexual abuse were associated with increased odds of alcohol-only use. Results suggest that sexual relationships and history of abuse/coercion are important factors in young African American women's substance use.

BACKGROUND: Chlamydia trachomatis (Ct) disproportionately affects African American young people living in the Southern United States and can have negative consequences if left untreated. Patient-delivered partner therapy (PDPT) is an evidence-based practice in which individuals diagnosed with Ct can provide treatment directly to their sex partners. However, PDPT acceptance rates need improvement. Although reasons for PDPT acceptance have been explored previously, the facilitators and barriers to expedited partner therapy acceptance among young southern African American men who have sex with women have not yet been examined. METHODS: Twenty semistructured interviews were conducted as part of a community-based Ct screening and treatment intervention among African American men aged 15 to 25 years who had female sex partners. Participants were asked about why they did or did not accept PDPT for their sex partners. Data were transcribed and analyzed in NVivo qualitative software using an inductive thematic approach. RESULTS: Participants' decision making was multifaceted. Facilitators for PDPT acceptance included being able to cure their partner, convenient access to treatment, believing it was the right thing to do, having a close relationship with a partner, concern for the partner's well-being, and the perceived severity of Ct. Barriers to PDPT acceptance were the belief that a partner did not need treatment, not having a close relationship with the partner, being unable to contact the partner, and fear of conflict. CONCLUSIONS: Findings had similarities to other studies, indicating some universal messaging may be warranted alongside culturally tailored interventions for specific patient populations to increase PDPT acceptance. Implications for patient-provider communication are provided.

BACKGROUND: COVID-19 stay-at-home orders enacted in New Orleans, LA on March 16, 2020, may have caused changes in the way young men interacted with sex partners. METHODS: An online substudy was conducted (May 21, 2020 to June 9, 2020) among Black men who have sex with women, 18 years and older, and who had previously enrolled in the parent study Check It (May 17, 2017 to March 6, 2020) to assess changes in sexual behavior during the stay-at-home orders. RESULTS: Among 111 participants, from enrollment in Check It to during stay-at-home orders, recent vaginal sex declined from 96.4% to 47.8% (P < 0.0001), reports of multiple female sex partners declined from 45.0% to 14.4% (P < 0.0001), and sexual abstinence increased from 3.6% to 38.7% (P < 0.0001). Among those who did have vaginal sex, condomless sex rates did not change between enrollment in Check It and the substudy (64.5% vs 67.9%, P = 0.68). During stay-at-home orders oral sex, virtual sex, and pornography viewing were 40.5%, 42.3%, and 76.6%, respectively. Some (17.1%) acquired a new sex partner during stay-at-home orders, and 44.1% left their home to meet a partner for sex. Only 27.9% had seen information about safe sex during the pandemic. Income was diminished for 62.2% and 23.4% moved away from New Orleans when stay-at-home orders were enacted. CONCLUSIONS: Although there was an overall reduction in physical sex, half of participants reported physical sex, with many leaving their home to have sex during stay-at-home orders and many not using condoms. Others adopted sexual abstinence, increased virtual sex, and/or pornography viewing, which may have protected them from both sexually transmitted infections and COVID-19.

BACKGROUND: Screening for asymptomatic Chlamydia trachomatis (Ct) among men has not been recommended because feasibility and efficacy are unknown. Check It is a seek-test-treat community-based Ct screening program for African American men who have sex with women and who are 15 to 24 years of age. This is an evaluation of adaptations made to the program aimed at improving index/partner notification and treatment rates. METHODS: The original Check It intervention included free testing and treatment, contact tracing performed by a third party, expedited index therapy, and expedited partner therapy via pharmacy pickup. The intervention was adapted after a series of in-depth interviews eliciting information to refine the program. Changes included continuity of testing, notification, and treatment by the same staff; expanded hours; and patient-delivered partner therapy with a medication mail-delivery option. Rates of index male and partner treatment were compared using log-binomial models and generalized estimating equations. RESULTS: Men in the adapted intervention (n = 85) were more likely than men in the original intervention (n = 99) to be contacted (relative risk [RR], 1.14; 95% confidence interval [CI], 1.02-1.27), make a treatment plan (RR, 1.14; 95% CI, 1.01-1.27), and complete treatment (RR, 1.45; 95% CI, 1.20-1.75). Female sexual partners were significantly more likely to complete treatment in postadaptation (n = 153) compared with preadaptation (n = 161; RR, 3.02; 95% CI, 1.81-5.05). CONCLUSIONS: Compared with third-party notification and expedited index therapy/expedited partner therapy available by pharmacy pickup only, patient-delivered partner therapy with mail-delivery option, staff available at nontraditional hours, and staff continuity across testing, notification, and treatment significantly improved index and partner treatment completion.

BACKGROUND: Trichomonas vaginalis virus (TVV) is a non-segmented, 4.5-5.5 kilo-base pair (kbp), double-stranded RNA virus infecting T. vaginalis. The objectives of this study were to examine the TVV prevalence in US Trichomonas vaginalis isolates and TVV's associations with patient demographics, clinical outcomes, and metronidazole resistance. METHODS: Archived T. vaginalis isolates from the enrollment visits of 355 women participating in a T. vaginalis treatment trial in Birmingham, Alabama, were thawed and grown in culture. Their total RNA was extracted using a Trizol reagent. Contaminating, single-stranded RNA was precipitated using 4.0 M Lithium Chloride and centrifugation. The samples were analyzed by gel electrophoresis to visualize a 4.5 kbp band representative of TVV. In vitro testing for metronidazole resistance was also performed on 25/47 isolates obtained from the women's test of cure visits. RESULTS: TVV was detected in 142/355 (40%) isolates at the enrollment visit. Women with TVV-positive (TVV+) isolates were significantly older (P = .01), more likely to smoke (P = .04), and less likely to report a history of gonorrhea (P = .04). There was no association between the presence of clinical symptoms or repeat T. vaginalis infections with TVV+ isolates (P = .14 and P = .44, respectively). Of 25 test of cure isolates tested for metronidazole resistance, 0/10 TVV+ isolates demonstrated resistance, while 2/15 TVV-negative isolates demonstrated mild to moderate resistance (P = .23). CONCLUSIONS: Of 355 T. vaginalis isolates tested for TVV, T. vaginalis isolates tested for TVV, the prevalence was 40%. However, there was no association of TVV+ isolates with clinical symptoms, repeat infections, or metronidazole resistance. These results suggest that TVV may be commensal to T. vaginalis.

BACKGROUND: The optimal timing for nucleic acid amplification testing (NAAT) posttreatment for Trichomonas vaginalis has not been fully established. Testing too soon posttreatment may detect remnant nucleic acid that is not from viable organisms, falsely misclassifying person as infected. The purpose of this study was to examine how long T. vaginalis nucleic acid is detectable postmetronidazole (MTZ) treatment. METHODS: Women diagnosed with T. vaginalis treated with MTZ (2 g single-dose or 500 mg twice daily for 7 days multidose) self-collected a vaginal swab for NAAT at baseline and each week postcompletion of treatment through test of cure (TOC) at week 4, when a culture was also performed. Women who reported interim sexual exposure or who were culture positive at 4 weeks were excluded. Time to first negative NAAT was examined using Kaplan Meier analysis. RESULTS: All women receiving multidose metronidazole were NAAT-negative by 21 days and those receiving single dose by 28 days postcompletion of treatment. Though over half (60.7%) of the cohort reinitiated sex during follow-up¸ all reported using condoms during sex or that they and their partner were treated before sex. Six (6.7%) of 89 had a positive NAAT following their first negative NAAT. CONCLUSIONS: The optimal timing for T. vaginalis retesting after completion of treatment is 3 weeks for those receiving multidose MTZ and 4 weeks for those receiving single-dose, though sexual reexposure and false negatives should be considered.

The objectives of this study were to: (1) describe the quantity and quality of social support networks of Latino immigrants living in a new receiving environment, and (2) determine the role such networks play in their HIV/STI risk behaviors, including substance use. Double incentivized convenience sampling was used to collect egocentric social support network data on 144 Latino immigrants. Latent class analysis was used for data reduction and to identify items best suited to measure quality and quantity of social support. Moderate and high quantity and quality of social support were protective of HIV/STI sexual risk behavior compared to low quantity and quality of support, after adjustment for gender, years in New Orleans and residing with family. Neither measure of social support was associated with binge drinking. The findings suggest that increased quantity and quality of social support decrease HIV/STI sexual risk behaviors but do not influence binge drinking. Interventions that improve the quantity and quality of social support are needed for Latino immigrants.

BACKGROUND: Three recent prospective studies have suggested that the 1-g dose of azithromycin for Chlamydia trachomatis (Ct) was less effective than expected, reporting a wide range of treatment failure rates (5.8%-22.6%). Reasons for the disparate results could be attributed to geographic or methodological differences. The purpose of this study was to reexamine the studies and attempt to harmonize methodologies to reduce misclassification as a result of false positives from early test-of-cure (TOC) or reinfection as a result of sexual exposure rather than treatment failure. METHODS: Men who had sex with women, who received 1-g azithromycin under directly observed therapy for presumptive treatment of nongonococcal urethritis with confirmed Ct were included. Baseline screening was performed on urethral swabs or urine, and TOC screening was performed on urine using nucleic acid amplification tests. Posttreatment vaginal sexual exposure was elicited at TOC. Data from the 3 studies were obtained and reanalyzed. Rates of Ct retest positive were examined for all cases, and a sensitivity analysis was conducted to either reclassify potential false positives/reinfections as negative or remove them from the analysis. RESULTS: The crude treatment failure rate was 12.8% (31/242). The rate when potential false positives/reinfections were reclassified as negative was 6.2% (15/242) or when these were excluded from analysis was 10.9% (15/138). CONCLUSIONS: In these samples of men who have sex with women with Ct-related nongonococcal urethritis, azithromycin treatment failure was between 6.2% and 12.8%. This range of failure is lower than previously published but higher than the desired World Health Organization's target chlamydia treatment failure rate of < 5%.

OBJECTIVE: Among women who are human immunodeficiency virus positive (HIV+), both prevalent and persistent infections with Trichomonas vaginalis (TV) are common. TV has been shown to increase vaginal shedding of HIV, which may influence HIV sexual and perinatal transmission, making prevention important. In 1 cohort of HIV+ women in Kenya, antiretroviral therapy (ART) use, mostly nevirapine based, was associated with lower cure rates of TV for single-dose therapy. Our goal was to repeat this study in a US-based cohort of HIV+/TV+ women and compare outcomes to those with multidose therapy. METHODS: A secondary data analysis was performed on a multicentered cohort of HIV+/TV+ women who were randomized to single-dose (2 grams) or 7-day (500 mg twice daily) multidose metronidazole (MTZ) treatment. Test of cure visit, via culture, occurred 6-12 days after treatment completion. Information was collected on sex partner treatment and sexual exposures. Persistent TV infection rates were compared for women on ART at baseline vs not on ART. RESULTS: Of the 226 women included, those on ART had more treatment failures than women not on ART (24/146 [16.4%] vs 5/80 [6.3%]; P = .03). When stratified by treatment arm, more treatment failures were seen in the single-dose arm (17/73 [23.3%] vs 3/39 [7.7%]; P = .05) than in the multidose arm (7/73 [9.6%] vs 2/41 [4.8%]; P = .39). CONCLUSIONS: ART usage was associated with a higher TV persistent infection rate among those receiving the single-dose treatment, but not the multidose, providing more evidence that multidose should be the preferred treatment for HIV+ women.

BACKGROUND: Trichomonas vaginalis (TV) and bacterial vaginosis (BV) are independently associated with increased risk of vaginal shedding in HIV-positive women. Because these 2 conditions commonly co-occur, this study was undertaken to examine the association between TV/BV co-occurrence and vaginal shedding of HIV-1 RNA. METHODS: HIV-positive women attending outpatient HIV clinics in 3 urban US cities underwent a clinical examination; were screened for TV, BV, Neisseria gonorrhoeae, Chlamydia trachomatis, and vulvovaginal candidiasis; and completed a behavioral survey. Women shedding HIV-1 RNA vaginally (≥50 copies/mL) were compared with women who had an undetectable (<50 copies/mL) vaginal viral load to determine if women who were TV positive and BV positive or had co-occurrence of TV/BV had higher odds of shedding vaginally when compared with women who did not have these conditions. RESULTS: In this sample of 373 HIV-positive women, 43.1% (n = 161) had co-occurrence of TV/BV and 33.2% (n = 124) were shedding HIV-1 RNA vaginally. The odds of shedding HIV vaginally in the presence of TV alone or BV alone and when TV/BV co-occurred were 4.07 (95% confidence interval [CI], 1.78-9.37), 5.65 (95% CI, 2.64-12.01), and 18.63 (95% CI, 6.71-51.72), respectively, when compared with women with no diagnosis of TV or BV, and after adjusting for age, antiretroviral therapy status, and plasma viral load. CONCLUSIONS: T. vaginalis and BV were independently and synergistically related to vaginal shedding of HIV-1 RNA. Screening and prompt treatment of these 2 conditions among HIV-positive women are important not only clinically but for HIV prevention, as well.

OBJECTIVES: Recently developed genotyping tools allow better understanding of Trichomonas vaginalis population genetics and epidemiology. These tools have yet to be applied to T vaginalis collected from HIV+ populations, where understanding the interaction between the pathogens is of great importance due to the correlation between T vaginalis infection and HIV transmission. The objectives of the study were twofold: first, to compare the genetic diversity and population structure of T vaginalis collected from HIV+ women with parasites from reference populations; second, to use the genetic markers to perform a case study demonstrating the usefulness of these techniques in investigating the mechanisms of repeat infections. METHODS: Repository T vaginalis samples from a previously described treatment trial were genotyped at 11 microsatellite loci. Estimates of genetic diversity and population structure were determined using standard techniques and compared with previously reported estimates of global populations. Genotyping data were used in conjunction with behavioural data to evaluate mechanisms of repeat infections. RESULTS: T vaginalis from HIV+ women maintain many of the population genetic characteristics of parasites from global reference populations. Although there is evidence of reduced diversity and bias towards type 1 parasites in the HIV+ population, the populations share a two-type population structure and parasite haplotypes. Genotyping/behavioural data suggest that 36% (12/33) of repeat infections in HIV+ women can be attributed to treatment failure. CONCLUSIONS: T vaginalis infecting HIV+ women is not genetically distinct from T vaginalis infecting reference populations. Information from genotyping can be valuable for understanding mechanisms of repeat infections.

Multiple sexual partnerships (MSP), both concurrent and serial short gap, are thought to increase the risk of HIV and sexually transmitted infection (STI) acquisition and transmission. In this study we evaluate potential individual and environmental risk factors for engaging in MSP in a cohort of newly arrived Latino migrant men (LMM) in New Orleans, LA, USA. Participants were surveyed at three time points over a nine-month period to examine factors associated with MSP. Of the 113 men, 32.5 % reported ever MSP. In 290 observations, 19.5 % of men had concurrent, and 15.0 % had serial short gap partnerships in at least one interviews. Substance was associated with MSP, OR (95 % CI) 2.00 (1.16, 3.45) whereas belonging to a community organization was found to be protective, OR 0.32 (0.17, 0.59).

Formative evaluation is a crucial strategy for health promotion program improvement. Early and ongoing formative evaluation can make a major impact on program outcomes; however, there are few frameworks that provide actual guidance on how programmatic or research teams can systematically perform this kind of important work. In this article we describe the use of an iterative real-time interview feedback framework we developed for Check It, a community-wide chlamydia screening and treatment program for young African American men in New Orleans, Louisiana. The framework considers the diverse and needed perspectives of multiple stakeholders, including participants, interviewers, transcribers, program staff, and lead researchers and/or administrators. Interviews were conducted with N = 15 Check It participants utilizing this approach. Employing the framework led to critical insights that resulted in several vital programmatic and evaluation improvements. Lessons learned, including strengths and challenges of utilizing the framework, are also shared so that this model can be replicated or adapted by program planning and evaluation professionals for other kinds of programs.

The purpose of this study was to examine patterns and predictors of HIV/STI risk over time among Latino migrant men in a new receiving community. Latino men (N = 125) were interviewed quarterly for 18 months and HIV/STI tested annually. Selected individual, environmental and cultural factors by partner type and condom use were explored longitudinally and in a cross-section. Sex with female sex workers (FSWs) and multiple partners decreased, sex with main partners and abstinence increased, while the number of casual partners remained stable. Consistent condom use was highest with FSWs, lowest with main partners and midrange with casual partners with no trends over time. STI morbidity was low; no HIV was detected. Drug use and high mobility were associated with inconsistent condom use with FSW, whereas having family in the household was protective. HIV/STI prevention efforts should focus on drug using Latino migrants who are highly mobile and should foster healthy social connections.

OBJECTIVE: Trichomonas vaginalis (TV) is common in HIV+ women, and host factors may play a role in TV treatment outcomes. The purpose of this study was to examine the influence of bacterial vaginosis (BV) on the response to TV treatment among HIV+ women. METHODS: A secondary analysis was conducted of a clinical trial which randomised HIV+/TV+ women to metronidazole (MTZ) treatment: 2 g (single-dose) versus 7 day 500 mg twice daily (multidose). BV was classified using Nugent scores from baseline Gram stains. Women were recultured for TV at test-of-cure (TOC) and again at 3 months if TV-negative at TOC. Repeat TV infection rates were compared for women with a baseline TV/BV coinfection versus baseline TV infection only, and stratified by treatment arm. RESULTS: Among 244 HIV+/TV+ women (mean age=40.3, ±9.5; 92.2% African-American), the rate of BV was 66.8%. Women with BV were more likely to report douching and ≥1 recent sex partners. HIV+ women with baseline TV/BV coinfection were more likely to be TV-positive at TOC than women with baseline TV infection only (RR 2.42 (95% CI 0.96 to 6.07; p=0.05)). When stratified by treatment arm, the association was only found in the single-dose arm (p=0.02) and not in the multidose arm (p=0.92). This interaction did not persist at 3 months. CONCLUSIONS: For HIV+/TV+ women, the rate of BV was high, and BV was associated with early failure of the MTZ single-dose treatment for TV. Biological explanations require further investigation.
