Missed opportunities for sexually transmitted infections testing for HIV pre-exposure prophylaxis users: a systematic review.

ABSTRACT:

Introduction

Given the synergistic relationship between HIV and sexually transmitted infections (STI), the integration of services has the potential to reduce the incidence of both HIV and STIs. We explored the extent to which STI testing has been offered within HIV pre-exposure prophylaxis (PrEP) programmes worldwide.

Methods

We conducted a systematic review of PrEP programmes implementing STI testing services in nine databases. We approached PrEP implementers for additional unpublished data and implementation details. Descriptive statistics were used to present the characteristics of STI testing within PrEP programmes. Content analysis of the input from PrEP implementers was conducted to summarize the barriers to and facilitators of STI testing.

Results

Of 9,161 citations, 91 studies conducted in 32 countries were included: 69% from high-income countries (HICs) and 64% from programmes targeting men who have sex with men (MSM) and transgender women (TGW) only. The majority of programmes (70%, 64/91) conducted STI testing before the initiation of PrEP. The most common STIs tested were gonorrhoea (86%, 78/91), chlamydia (84%, 76/91) and syphilis (84%, 76/91). The majority provided STI testing at three-month intervals (70%, 53/76, for syphilis; 70% 53/78, for chlamydia; 68%, 53/78, for gonorrhoea). Relative to low- and middle-income countries (LMICs), a higher proportion of PrEP programmes in HICs offered testing for gonorrhoea (92% vs. 71%, p < 0.05), chlamydia (92% vs. 64%, p < 0.01), syphilis (87% vs. 75%, p < 0.05), hepatitis A (18% vs. 4%, p < 0.05) and hepatitis C (43% vs. 21%, p < 0.05); offered testing for a higher number of STIs (mean 3.75 vs. 3.04, p < 0.05); and offered triple (throat, genital/urine and anorectal) anatomical site screening (54% vs. 18%, p < 0.001). Common implementation challenges included costs, access to STI diagnostics, programme logistics of integrating STI testing into PrEP delivery models and lack of capacity building for staff involved in PrEP provision.

Conclusions

Significant gaps and challenges remain in the provision of STI testing services within HIV PrEP programmes. We recommend more active integration of STI testing and management into PrEP programmes, supported by standardized practice guidelines, staff capacity building training and adequate funding. This could lead to improved sexual health and HIV outcomes in key populations.

Project description:Women in Africa face disproportionate risk of human immunodeficiency virus (HIV) acquisition, accounting for more than half of new infections in Africa and similarly face a disproportionate burden of sexually transmitted infections (STIs). Very high STI prevalence is being observed globally, especially among people taking pre-exposure prophylaxis (PrEP) for HIV prevention. Doxycycline post-exposure prophylaxis (dPEP) has been proposed as an STI prevention strategy to reduce chlamydia, syphilis, and possibly gonorrhea, and trials are ongoing among cisgender men who have sex with men (MSM) and transgender women who are taking PrEP in high-income settings. We designed and describe here the first open-label trial to determine the effectiveness of dPEP to reduce STI incidence among cisgender women. We are conducting an open-label 1:1 randomized trial of dPEP versus standard of care (STI screening and treatment and risk-reduction counseling without dPEP) among 446 Kenyan women aged ≥ 18 and ≤ 30 years old women taking PrEP. Women are followed for 12 months, with quarterly STI testing, treatment, and adherence counseling. The primary trial outcome will be the combined incidence of Chlamydia trachomatis, Neisseria gonorrhoeae, and Treponema pallidum, compared between the randomized groups. We will also assess dPEP acceptability, tolerability, safety, impact on sexual behavior, adherence, and occurrence of antimicrobial resistance (AMR) in N. gonorrhoeae and C. trachomatis isolates. Finally, we will estimate cost per incident STI case and complications averted accounting for nonadherence and benefits relative AMR or side effects. The results of this trial may have immediate implications for the global epidemic of STIs and sexual health. If effective, dPEP could put STI prevention into women's hands. While dPEP may be able to prevent STIs, it carries important risks that could counter its benefits; global debate about the balance of these potential risks and benefits requires data to inform policy and implementation and our study aims to fill this gap.

Project description:Background:Pre-exposure prophylaxis (PrEP) is highly effective for preventing HIV infections, but is not yet implemented in the Netherlands. As the attitudes of health-care professionals toward PrEP can influence future PrEP implementation, we studied PrEP knowledge and beliefs and their association with PrEP acceptability among professionals in clinics for sexually transmitted infection (STI professionals) and HIV treatment centers (HIV specialists). In addition, we examined preferred regimens, attitudes toward providing PrEP to key populations and to reimbursement of PrEP costs. Methods:An online questionnaire was distributed among 24 public health STI clinics and 27 HIV treatment centers nationwide in the Netherlands between January and August 2015. The acceptability of PrEP was measured on a 7-point Likert scale ranging from 1?=?low to 7?=?high acceptability. Univariable and multivariable linear regression analyses were used to explore associations between demographic characteristics, PrEP knowledge, beliefs about PrEP, and PrEP acceptability. Results:In total, 209 people (143 STI professionals and 66 HIV specialists) completed the questionnaire. The mean acceptability of PrEP implementation was 4.28 (SD 1.68) among STI professionals and 4.42 (SD 1.67) among HIV specialists. The mean score on self-perceived knowledge related to PrEP efficacy was 3.90 (SD 1.57) among STI professionals and 5.68 (SD 1.08) among HIV specialists (p-value of <0.001). Beliefs associated with lower PrEP acceptability among both groups were the fear that PrEP use will lead to a decrease in condom use and an increase in STI, the high costs of PrEP and ethical issues regarding prescribing antiretroviral medication to healthy individuals. No preference for a daily or an event-driven regimen was detected. Most participants deemed the following groups to be eligible for PrEP: men who have sex with men (MSM) who regularly get post-exposure prophylaxis, MSM who never used condoms with casual partners and MSM with an HIV-positive partner with a detectable viral load. Over half of the participants indicated that PrEP users should partly (54.1%) or fully (35.4%) pay the costs of PrEP. Conclusion:In 2015, PrEP acceptability was only moderate among Dutch STI professionals and HIV specialists, which is far from an optimal setting. Addressing barriers to PrEP acceptability in educational programs for various types of health-care professionals is needed to successfully implement PrEP in the Netherlands.
