Randomized controlled trial on the effectiveness of counseling messages for avoiding unprotected sexual intercourse during sexually transmitted infection and reproductive tract infection treatment among female sexually transmitted infection clinic patients

Effectiveness of erectogenic condom against semen exposure among women in Vietnam: Randomized controlled trial

A key barrier to the consistent use of condoms is their negative effect on sexual pleasure. Although sexual pleasure is a primary motivation for engaging in sex and is an integral part of overall sexual health, most programs to improve sexual health operate within a pregnancy and disease-prevention paradigm. A new condom, CSD500 (Futura Medical Developments; Surrey, UK), containing an erectogenic drug was developed for use among healthy couples to improve sexual pleasure by increasing penile firmness, size and erection duration. We conducted a randomized controlled trial to test whether promoting the novel condom CSD500 for improved sexual pleasure is effective in reducing condomless sex compared to the provision of standard condoms with counseling for pregnancy and disease prevention. We randomized 500 adult, heterosexual, monogamous couples in Thanh Hoa province, Vietnam to receive either CSD500 (n = 248) or standard condoms (n = 252). At enrollment and after 2, 4, and 6 months, we interviewed women and sampled vaginal fluid to test for the presence of prostate-specific antigen (PSA), an objective, biological marker of recent semen exposure. We registered the protocol before trial initiation at ClinicalTrials.gov (identifier: NCT02934620). Overall, 11.0% of women were PSA positive at enrollment. The proportion of follow-up visits with PSA-positivity did not differ between the intervention (6.8%) and control arms (6.7%; relative risk, 1.01; 95% confidence interval, 0.66-1.54). Thus, we found no evidence that promoting an erectogenic condom to women in a monogamous, heterosexual relationship in Vietnam reduced their exposure to their partner's semen. These findings might not hold for other populations, especially those with a higher frequency of condomless sex.

Sexually Transmitted Infections Treatment Guidelines, 2021

These guidelines for the treatment of persons who have or are at risk for sexually transmitted infections (STIs) were updated by CDC after consultation with professionals knowledgeable in the field of STIs who met in Atlanta, Georgia, June 11-14, 2019. The information in this report updates the 2015 guidelines. These guidelines discuss 1) updated recommendations for treatment of Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis; 2) addition of metronidazole to the recommended treatment regimen for pelvic inflammatory disease; 3) alternative treatment options for bacterial vaginosis; 4) management of Mycoplasma genitalium; 5) human papillomavirus vaccine recommendations and counseling messages; 6) expanded risk factors for syphilis testing among pregnant women; 7) one-time testing for hepatitis C infection; 8) evaluation of men who have sex with men after sexual assault; and 9) two-step testing for serologic diagnosis of genital herpes simplex virus. Physicians and other health care providers can use these guidelines to assist in prevention and treatment of STIs.

Intravaginal Practices Among Women Attending a Sexually Transmitted Disease Clinic-Philadelphia, 2017

ABSTRACT

We conducted a survey among women attending an urban public sexually transmitted disease clinic to determine the type and frequency of intravaginal cleansing practices. Both intravaginal washing and douching were frequent, performed mostly for routine hygiene, and associated with self-report of sexually transmitted infection and bacterial vaginosis (douching and intravaginal washing).

Risky Sexual Behavior and Associated Factors among Adolescents Aged 15-19 Years at Governmental High Schools in Aksum Town, Tigray, Ethiopia, 2019: An Institution-Based, Cross-Sectional Study

INTRODUCTION

The impact of risky sexual practice on the general health of adolescents is enormous; little attention has been given on identification and intervention plans. Therefore, the aim of this study was to find the magnitude of risky sexual behavior and associated factors among adolescents aged 15-19 years in high schools at Aksum town, Tigray, Ethiopia.

METHODS

An institution-based cross-sectional study was conducted at governmental high schools of Aksum town. We recruited a total of 659 adolescents aged 15-19 years by using a systematic random sampling technique. Data was collected with a face-to-face interview. An Amharic version of the sexual risk behavior scale was used to measure risky sexual behaviors. The patient health questionnaire 9, the Oslo-3 social support scale, and an adverse childhood experience questionnaire were used to assess the factors. The coded data were entered into EpiData v.4.1 and analyzed using Statistical Package for the Social Sciences version 22. Bivariate and multivariate logistic regressions were done. An adjusted odds ratio at a p value < 0.05 with 95% confidence interval was taken to declare statistical significance.

RESULT

A total of 644 students have participated with a response rate of 97.7%. The prevalence of risky sexual behavior among adolescents aged 15-19 years was found to be 17.2%. Factors like poor social support (AOR = 5.59, 95% CI: 2.71-11.53), living out of family (AOR = 1.93, 95% CI: 1.21-3.07), experiencing parental neglect (AOR = 1.87, 95% CI: 1.18-2.94), and drinking alcohol (AOR = 2.55, 95% CI: 1.55-4.20) were statistically associated with risky sexual behavior. Conclusion and Recommendations. The prevalence of risky sexual behavior was found to be alarming among adolescents of high school aged 15-19 years. This can significantly affect health quality in the community and the country at large. We recommend setting strategies that are against the determining factors of risky sexual behavior; the control of alcoholic beverages among adolescents aged 15-19 years must be enhanced, and awareness creation must be made regarding its unpleasant consequences.

PrEP Use Among Female Sex Workers: No Evidence for Risk Compensation

Supplemental Digital Content is Available in the Text.

Little is known about risk compensation among female sex workers (FSW) on HIV pre-exposure prophylaxis (PrEP), and self-report of sexual behaviors is subject to bias.

A novel nested polymerase chain reaction targeting the testis-specific protein Y-encoded family of genes for high sensitivity of recent semen exposure detection: Comparison with four other assays of semen detection

OBJECTIVES

Because self-report of sexual behaviours is prone to biases, biomarkers of recent semen exposure are increasingly used to assess unprotected sex. We aimed to present a novel nested polymerase chain reaction (PCR) assay targeting testis-specific protein Y-encoded (TSPY) genes and to compare its performance in detecting recent semen exposure with that of four other assays.

METHODS

Forty-five vaginal samples were selected at baseline of a prospective observational demonstration study of early antiretroviral treatment and pre-exposure prophylaxis among female sex workers in Benin. Semen exposure was assessed with: a rapid prostate-specific antigen (PSA) detection assay, a quantitative PCR targeting the sex-determining region (SRY) gene, a standard PCR targeting SRY, a standard PCR targeting TSPY, and a nested PCR targeting TSPY (n-TSPY). Because we had hypothesized that n-TSPY would be the most sensitive of the five assays while remaining specific, and as our results suggested that it was the case, sensitivity and specificity were calculated for each assay in comparison with n-TSPY.

RESULTS

The n-TSPY could detect male DNA at concentration 16 and 64 times lower compared to s-TSPY and s-SRY, respectively. Among the 45 vaginal samples, prevalences of semen exposure according to the different assays varied from 22.2% (95%CI: 11.2%-37.1%) to 70.5% (95%CI: 54.8%-83.2%), with the highest prevalence measured with n-TSPY. The n-TSPY products were of expected size and we observed no false-positive in female DNA controls. The assay that offered the second best performance in detecting semen exposure was the PSA rapid test, with a sensitivity of 61.3% and a specificity of 100% compared to n-TSPY.

CONCLUSIONS

Compared to n-TSPY, all other PCR assays had poor performance to detect semen exposure. The n-TSPY is an accessible assay that may have great utility in assessing semen exposure in studies where many factors are expected to accelerate biomarkers' clearance.

Sexual Relationship Power and Semen Exposure Among Female Patients at a Sexually Transmitted Infection Clinic in Kingston, Jamaica

Women's power in sexual relationships is thought to be an important predictor of condom use. However, research on correlates of condom use often relies on participant reporting of behavior, which has questionable validity. We evaluated the association between scores from the modified Sexual Relationship Power Scale (SRPS-M) and biological detection of semen exposure in a prospective study of adult women attending a sexually transmitted infection clinic in Kingston, Jamaica with cervicitis or abnormal vaginal discharge in 2010-2011. At enrollment, women were counseled to avoid sex while on treatment and were asked to return in 6 days for a follow-up visit. At both study visits, women were administered a questionnaire and had vaginal swabs collected to test for prostate-specific antigen (PSA), a biological marker of recent semen exposure. We found no significant association at enrollment or follow-up between SRPS-M scores and semen exposure, as measured with either self-reported data or PSA positivity. Semen biomarkers could be used to develop and validate new scales on relationship power and self-efficacy related to condom use.

Test-Retest Reliability of Self-Reported Sexual Behavior History in Urbanized Nigerian Women

BACKGROUND

Studies assessing risk of sexual behavior and disease are often plagued by questions about the reliability of self-reported sexual behavior. In this study, we evaluated the reliability of self-reported sexual history among urbanized women in a prospective study of cervical HPV infections in Nigeria.

METHODS

We examined test-retest reliability of sexual practices using questionnaires administered at study entry and at follow-up visits. We used the root mean squared approach to calculate within-person coefficient of variation (CVw) and calculated the intra-class correlation coefficient (ICC) using two way, mixed effects models for continuous variables and [Formula: see text] statistics for discrete variables. To evaluate the potential predictors of reliability, we used linear regression and log binomial regression models for the continuous and categorical variables, respectively.

RESULTS

We found that self-reported sexual history was generally reliable, with overall ICC ranging from 0.7 to 0.9; however, the reliability varied by nature of sexual behavior evaluated. Frequency reports of non-vaginal sex (agreement = 63.9%, 95% CI: 47.5-77.6%) were more reliable than those of vaginal sex (agreement = 59.1%, 95% CI: 55.2-62.8%). Reports of time-invariant behaviors were also more reliable than frequency reports. The CVw for age at sexual debut was 10.7 (95% CI: 10.6-10.7) compared with the CVw for lifetime number of vaginal sex partners, which was 35.2 (95% CI: 35.1-35.3). The test-retest interval was an important predictor of reliability of responses, with longer intervals resulting in increased inconsistency (average change in unreliability for each 1 month increase = 0.04, 95% CI = 0.07-0.38, p = 0.005).

CONCLUSION

Our findings suggest that overall, the self-reported sexual history among urbanized Nigeran women is reliable.

Substance use and STI acquisition: Secondary analysis from the AWARE study

OBJECTIVES

Sexually transmitted infections (STIs) are significant public health and financial burdens in the United States. This manuscript examines the relationship between substance use and prevalent and incident STIs in HIV-negative adult patients at STI clinics.

METHODS

A secondary analysis of Project AWARE was performed based on 5012 patients from 9 STI clinics. STIs were assessed by laboratory assay and substance use by self-report. Patterns of substance use were assessed using latent class analysis. The relationship of latent class to STI rates was investigated using Poisson regression by population groups at high risk for STIs defined by participant's and partner's gender.

RESULTS

Drug use patterns differed by risk group and substance use was related to STI rates with the relationships varying by risk behavior group. Substance use treatment participation was associated with increased STI rates.

CONCLUSIONS

Substance use focused interventions may be useful in STI clinics to reduce morbidity associated with substance use. Conversely, gender-specific sexual health interventions may be useful in substance use treatment.

Sexual abstinence and other behaviours immediately following a new STI diagnosis among STI clinic patients: Findings from the Safe in the City trial

BACKGROUND

Few studies have assessed patients' sexual behaviours during the period immediately following a new diagnosis of a curable sexually transmitted infection (STI).

METHODS

Data were analysed from a behavioural study nested within the Safe in the City trial, which evaluated a video-based STI/HIV prevention intervention in three urban STI clinics. We studied 450 patients who reported having received a new STI diagnosis, or STI treatment, 3 months earlier. Participants reported on whether they seriously considered, attempted and succeeded in adopting seven sex-related behaviours in the interval following the diagnostic visit. We used multivariable logistic regression to identify, among men, correlates of two behaviours related to immediately reducing reinfection risk and preventing further STI transmission: sexual abstinence until participants were adequately treated and abstinence until their partners were tested for STIs.

RESULTS

Most participants reported successfully abstaining from sex until they were adequately treated for their baseline infection (89%-90%) and from sex with potentially exposed partners until their partners were tested for HIV and other STIs (66%-70%). Among men who intended to be abstinent until they were adequately treated, those who did not discuss the risks with a partner who was possibly exposed were more likely not to be abstinent (OR, 3.7; 95% CI 1.5 to 9.0) than those who had this discussion. Similarly, among men who intended to abstain from sex with any potentially exposed partner until the partner was tested for HIV and other STIs, those who reported not discussing the risks of infecting each other with HIV/STIs were more likely to be sexually active during this period (OR, 3.5; 95% CI 1.6 to 8.1) than were those who reported this communication.

CONCLUSIONS

Improved partner communication could facilitate an important role in the adoption of protective behaviours in the interval immediately after receiving a new STI diagnosis.

Effects of initiating a contraceptive implant on subsequent condom use: A randomized controlled trial

OBJECTIVE

To evaluate whether initiation of a contraceptive implant, a method of long-acting reversible contraception, reduces condom use, as measured by a biomarker of recent semen exposure [prostate-specific antigen (PSA)].

STUDY DESIGN

We conducted a randomized controlled clinical trial in which 414 Jamaican women at high risk for sexually transmitted infections (STIs) attending family planning clinics received the contraceptive implant at baseline ("immediate" insertion arm, N=208) or at the end ("delayed" insertion arm, N=206) of a 3-month study period. Participants were tested for PSA at baseline and two follow-up study visits and were asked about their sexual activity and condom use.

RESULTS

At baseline, 24.9% of women tested positive for PSA. At both follow-up visits, the prevalence of PSA detection did not significantly differ between the immediate versus delayed insertion arm [1-month: 26.1% vs. 20.2%, prevalence ratio (PR)=1.3, 95% confidence interval (CI)=0.9-1.9; 3-month: 25.6% vs. 23.1%, PR= 1.1, 95% CI=0.8-1.6]. The change in PSA positivity over the three study visits was not significantly larger in the immediate arm compared to the delayed arm (1-sided p-value of .15).

CONCLUSIONS

Contraceptive implants can be successfully introduced into a population at high risk of unintended pregnancy and STIs without a biologically detectable difference in unprotected sex in the short term. This information strengthens the evidence to support promotion of implants in such populations and can help refine counseling for promoting and maintaining use of condoms among women who choose to use implants.

IMPLICATIONS

Sex unprotected by a condom was not higher over 3 months in women receiving a contraceptive implant, compared with those not receiving the implant.

Differences in misreporting of sexual behavior over time: implications for HIV trials

We used data from a prospective study of 300 women attending a sexually transmitted infection clinic in Kingston, Jamaica, to compare participant self-report of recent semen exposure to actual semen exposure measured by prostate-specific antigen in vaginal swabs. Underreporting of semen exposure was significantly more frequent at follow-up than baseline, suggesting that the accuracy of reports of sexual behavior may vary over time.

Sexually transmitted diseases treatment guidelines, 2015

These guidelines for the treatment of persons who have or are at risk for sexually transmitted diseases (STDs) were updated by CDC after consultation with a group of professionals knowledgeable in the field of STDs who met in Atlanta on April 30-May 2, 2013. The information in this report updates the Sexually Transmitted Diseases Treatment Guidelines, 2010 (MMWR Recomm Rep 2010;59 [No. RR-12]). These updated guidelines discuss 1) alternative treatment regimens for Neisseria gonorrhoeae; 2) the use of nucleic acid amplification tests for the diagnosis of trichomoniasis; 3) alternative treatment options for genital warts; 4) the role of Mycoplasma genitalium in urethritis/cervicitis and treatment-related implications; 5) updated HPV vaccine recommendations and counseling messages; 6) the management of persons who are transgender; 7) annual testing for hepatitis C in persons with HIV infection; 8) updated recommendations for diagnostic evaluation of urethritis; and 9) retesting to detect repeat infection. Physicians and other health-care providers can use these guidelines to assist in the prevention and treatment of STDs.

An application of propensity score weighting to quantify the causal effect of rectal sexually transmitted infections on incident HIV among men who have sex with men

Background

Exploring causal associations in HIV research requires careful consideration of numerous epidemiologic limitations. First, a primary cause of HIV, unprotected anal intercourse (UAI), is time-varying and, if it is also associated with an exposure of interest, may be on a confounding path. Second, HIV is a rare outcome, even in high-risk populations. Finally, for most causal, non-preventive exposures, a randomized trial is impossible. In order to address these limitations and provide a practical illustration of efficient statistical control via propensity-score weighting, we examine the causal association between rectal STI and HIV acquisition in the InvolveMENt study, a cohort of Atlanta-area men who have sex with men (MSM). We hypothesized that, after controlling for potentially confounding behavioral and demographic factors, the significant STI-HIV association would attenuate, but yield an estimate of the causal effect.

Methods

The exposure of interest was incident rectal gonorrhea or chlamydia infection; the outcome was incident HIV infection. To adjust for behavioral confounding, while accounting for limited HIV infections, we used an inverse probability of treatment weighted (IPTW) Cox proportional hazards (PH) model for incident HIV. Weights were derived from propensity score modeling of the probability of incident rectal STI as a function of potential confounders, including UAI in the interval of rectal STI acquisition/censoring.

Results

Of 556 HIV-negative MSM at baseline, 552 (99%) men were included in this analysis. 79 men were diagnosed with an incident rectal STI and 26 with HIV. 6 HIV-infected men were previously diagnosed with a rectal STI. In unadjusted analysis, incident rectal STI was significantly associated with subsequent incident HIV (HR (95%CI): 3.6 (1.4-9.2)). In the final weighted and adjusted model, the association was attenuated and more precise (HR (95% CI): 2.7 (1.2-6.4)).

Conclusions

We found that, controlling for time-varying risk behaviors and time-invariant demographic factors, diagnosis with HIV was significantly associated with prior diagnosis of rectal CT or GC. Our analysis lends support to the causal effect of incident rectal STI on HIV diagnosis and provides a framework for similar analyses of HIV incidence.

Prostate-specific antigen is unlikely to be a suitable biomarker of semen exposure from recent unprotected receptive anal intercourse in men who have sex with men

A biomarker of unprotected receptive anal intercourse could improve validity of sexual behavior measurement. We quantified prostate-specific antigen (PSA) from rectal swabs from men who have sex with men (MSM). One swab was PSA positive. Using current methods, PSA is an inadequate biomarker of recent unprotected receptive anal intercourse in men who have sex with men.

Review of HIV in the Caribbean: significant progress and outstanding challenges

This paper reviews the recent literature on HIV in the Caribbean and discusses the challenges faced. HIV incidence in the Caribbean has declined by 49 % in the past decade, coverage of persons living with HIV among those eligible for antiretroviral treatment as per national guidelines was 70 % in 2012, and some countries are meeting the target of virtual elimination of mother-to-child transmission. HIV prevalence in the Caribbean is 1 % with features of both a generalized and concentrated HIV epidemic. HIV prevalence among female sex workers has declined but remains unacceptably high among men who have sex with men. Social and cultural factors, gender norms, and strong stigma associated with HIV and homosexuality contribute to the continued spread of HIV. Caribbean countries and their partners have invested significant resources, creative effort and impressive research in strengthening the HIV response nationally and regionally. However, in order to control the HIV epidemic, leaders at all levels, and the people, must address fundamental structural barriers in society that deny marginalized persons their rights, undermine public health goals, and impede universal access to HIV prevention, treatment, and care.

The use of biomarkers of semen exposure in sexual and reproductive health studies

Biomarkers of semen exposure have been used in studies investigating the safety and efficacy of barrier methods of contraception. They have been used as objective indicators of semen exposure when studying sexual behaviors and in human immunodeficiency virus/sexually transmitted infection research interventions where participants are advised to avoid unprotected sex. Semen biomarkers have also been used to assess or validate self-reported sexual behaviors or condom use in reproductive health settings. Prostate-specific antigen (PSA) and Y chromosome DNA (Yc-DNA) have each been evaluated in the past as semen biomarkers and are the most widely used in the field. While both are considered reliable for evaluating exposure to semen, each has unique characteristics. In this report, we summarize the literature and provide some considerations for reproductive health researchers who are interested in using PSA or Yc-DNA as semen biomarkers. We also synthesize our previous published work on the optimal conditions of collecting and storing specimens and assay performance in the presence of other vaginal products that may influence various assays. Semen biomarkers are innovative and promising tools to further study and better understand women's reproductive and sexual health and behavior. More research is needed to better understand the strengths, limitations, and optimal performance conditions of specific assays in vivo.

Biological markers of sexual activity: tools for improving measurement in HIV/sexually transmitted infection prevention research

Research on interventions to prevent HIV and other sexually transmitted infections (STIs) is heavily influenced by participant reporting of sexual behavior, despite uncertainty about its validity. Exclusive reliance on participant self-report often is based, overtly or by implication, on 4 assumptions: (1) no feasible alternatives exist; (2) misreporting can be minimized to levels that can be disregarded; (3) misreporting tends to underreport sensitive behaviors; and (4) misreporting tends to be nondifferential with respect to the groups being compared. The objective of this review are to evaluate these assumptions, including a review of studies using semen biomarkers to evaluate the validity of self-reported data, and to make recommendations for applying biological markers of semen exposure detectable in women to further strengthen research on HIV/STI prevention. Increasing evidence shows that semen biomarkers provide an important means of assessing and augmenting the validity of studies on HIV/STI prevention. Additional biomarkers are needed to assess male exposure to vaginal sex and both male and female exposure to anal sex. Methods and study designs that incorporate biomarkers into studies collecting self-reported behavioral data should be considered where possible.

Intravaginal cleansing among women attending a sexually transmitted infection clinic in Kingston, Jamaica

OBJECTIVES

Although common worldwide, intravaginal cleansing is associated with poor health outcomes. We sought to describe intravaginal cleansing among women attending a sexually transmitted infection (STI) clinic in Jamaica.

METHODS

We examined intravaginal cleansing ("washing up inside the vagina", douching, and products or materials used) among 293 participants in a randomized trial of counselling messages at an STI clinic in Kingston. We focussed on information on intravaginal cleansing performed in the 30 days and three days preceding their baseline study visit. We describe reported cleansing behaviours and used logistic regression to identify correlates of intravaginal cleansing.

RESULTS

Fifty-eight per cent of participants reported intravaginal cleansing in the previous 30 days, and 46% did so in the three days before baseline. Among those who cleansed in the previous 30 days, 88% reported doing so for hygiene unrelated to sex, and three-fourths reported generally doing so more than once per day. Soap (usually with water) and water alone were the most common products used for washing; commercial douches or detergents were reported infrequently. Intravaginal cleansing in the three days before the baseline visit was positively associated with having more than one sex partner in the previous three months (adjusted odds ratio [AOR], 1.9; 95% CI, 1.1, 3.2), and negatively associated with experiencing itching in the genital area at baseline (AOR, 0.6; 95% CI, 0.4, 1.0).

CONCLUSIONS

A large proportion of women attending STI clinics in Jamaica engage in frequent intravaginal cleansing, indicating a need for clinicians to discuss this topic with them accordingly.
