HIV disproportionally affects key populations including men who have sex with (MSM). prevalence among MSM varies from 17% in Brazil and Mexico to 13% Peru, whereas it is below 0.5% for the general population each country. Pre-exposure prophylaxis (PrEP) emtricitabine/tenofovir being implemented context of combination prevention. Reports on willingness use PrEP started emerge over last few years. Previously reported factors associated include awareness, higher sexual risk behavior, previous...
In spite of its immutable susceptibility to penicillin, Treponema pallidum ( T . ) subsp. continues cause millions cases syphilis each year worldwide, resulting in significant morbidity and mortality underscoring the urgency developing an effective vaccine curtail spread infection. Several technical challenges, including absence vitro culture system until very recently, have hampered efforts catalog diversity strains collected worldwide. Here, we provide near-complete genomes from 196...
Although gay, bisexual, and other cisgender men who have sex with (MSM) transgender women the highest HIV burden in Latin America, pre-exposure prophylaxis (PrEP) implementation is poor. We aimed to assess feasibility of same-day oral PrEP delivery Brazil, Mexico, Peru.Implementation (ImPrEP) was a prospective, single-arm, open-label, multicentre study conducted Brazil (14 sites), Mexico (four Peru (ten sites). MSM were eligible participate if they aged 18 years or older, HIV-negative,...
Abstract Introduction The HIV epidemic continues to disproportionately impact Latin‐American transgender women (TGW). We assessed factors associated with long‐term pre‐exposure prophylaxis (PrEP) engagement and adherence among TGW enrolled in the Implementation of PrEP (ImPrEP) study, largest demonstration study Latin America. Methods HIV‐negative aged ≥18 years reporting 1+eligibility criteria 6 months prior enrolment (e.g. sex partner known be living HIV, condomless anal [CAS],...
Abstract Background Most forcibly displaced persons are hosted in low- and middle-income countries (LMIC). There is a growing urbanization of persons, whereby most refugees nearly half internally live urban areas. This scoping review assesses the sexual reproductive health (SRH) needs, outcomes, priorities among living LMIC. Methods Following The Joanna Briggs Institute methodology we searched eight databases for literature published between 1998 2023 on SRH needs SHR was operationalized as...
Abstract Background Syphilis rates have been increasing. At the same time, important shortages of benzathine penicillin G reported. Existing alternatives, doxycycline, tetracycline, and azithromycin are inadequate to treat syphilis in all patients due absence safety data pregnancy children, or antibiotic resistance, respectively. Linezolid is an FDA-approved, safe, low-cost, oral that crosses blood-brain barrier. It has shown efficacy against Treponema pallidum vitro animal studies. Although...
Background: Men who have sex with men (MSM) and male-to-female transgender women (TW) are at increased risk of HIV sexually transmitted infections (STIs). We evaluated factors associated incidence HIV, HSV-2, chlamydia gonorrhea (anal pharyngeal). Methods: used data from the Comunidades Positivas trial MSM/TW in Lima, Peru. Participants were asked about sexual behaviors underwent HIV/STI testing baseline 9- 18-month follow-ups. discrete time proportional hazards regression to calculate...
HIV status awareness is key to prevention, linkage-to-care and treatment. Our study evaluated the accessibility potential willingness of self-testing among men who have sex with (MSM) transgender women in Peru. We surveyed four pharmacy chains Peru ascertain commercial availability oral self-test. The pharmacies confirmed that self-test kits were available; however, those available not intended for individual use, but clinician use. interviewed 147 MSM 45 women; nearly all (82%) reported...
Increased HIV testing frequency among high-risk populations such as men who have sex with (MSM) and male-to-female transgender women (TW) can lead to earlier treatment potentially reduce transmission.
HIV incidence estimation is critical for monitoring the epidemic dynamics and effectiveness of public health prevention interventions. We aimed to identify sexual gender minorities (SGM) with recent infections, factors associated infection, estimate annualised rates.
Background Further research is necessary to understand the factors contributing high prevalence of HIV/STIs among men who have sex with (MSM) in Peru. We compared HIV/STI and risk between two non-probability samples MSM, one passively enrolled from an STI clinic other actively community venues surrounding Lima, Methods A total 560 self-identified MSM were May-December, 2007. 438 subjects a municipal 122 during outreach visits. All participants underwent screening for HIV, syphilis, HSV-2,...
Pre-exposure prophylaxis (PrEP) scale-up is urgent to reduce new HIV cases among gay, bisexual, and other men who have sex with (MSM) in Latin America. Different PrEP modalities may increase uptake adherence, especially young MSM.
Abstract Background Syphilis has reemerged as a global health concern. The standard treatment for all stages of syphilis is injectable benzathine penicillin G. Cefixime an FDA-approved, oral antibiotic widely available, low-cost, and safe in pregnancy. A previous pilot study showed cefixime was likely efficacious treating early syphilis. This aims to evaluate the efficacy comparison Methods We are conducting randomized, multisite, open-label, non-inferiority clinical trial compare...
Abstract Background Benzathine penicillin is the antimicrobial treatment of choice for syphilis, but worldwide shortages have caused disruptions in patient care. Therefore, a need new compounds that are effective at curing Treponema pallidum subsp. (Tp) infections not subject to same supply chain issues currently effecting benzathine availability. To this end, we tested vitro susceptibility four different strains Tp (Nichols, Mexico A, UW231B, and UW249B) linezolid. Methods There two...
Abstract Introduction: The Peruvian public healthcare system is characterized by various shortcomings that adversely affect quality as perceived the general and minority populations, including Afro-Peruvian community. This population has demonstrated reduced access due to discrimination differential treatment, reflecting broader societal inequities. Objective: study explores experiences perceptions of individuals regarding treatment they receive from primary providers in metropolitan Lima....
Decentralizing HIV services is an evidence-based strategy recommended by the World Health Organization to expand healthcare access shifting most care from specialty (SHCs) primary health centers (PHCs) with goal of maximizing outcomes. To accelerate Peru Ministry Health's 2020 priority transition centers, we assessed multilevel stakeholders' perspectives on barriers and opportunities for scaling-up decentralization care. Between January March 2024, used nominal group technique (NGT), a...
