Amphetamine-Type Stimulant Use and Associated Factors Among Men Who have Sex with Men in Bangkok.

Amphetamine-type stimulants (ATS) have become prevalent among men who have sex with men (MSM), often associated with a higher risk of HIV acquisition. However, little is known about ATS use among MSM in Thailand. This study identifies ATS use patterns and associated factors among MSM in Bangkok, Thailand.

The natural history of anal high-grade squamous intraepithelial lesions among MSM and transgender women in an acute HIV cohort in Thailand.

Objective: To describe the incidence and clearance rates of anal high-grade squamous intraepithelial lesions (HSIL) among MSM and transgender women who initiated immediate antiretroviral therapy during acute HIV acquisition.

Design: A prospective cohort study of MSM and transgender women diagnosed with acute HIV acquisition in Bangkok, Thailand.

Methods: Participants who were enrolled from May 2017 to June 2020 underwent anal human papillomavirus (HPV) genotyping, high-resolution anoscopy, and anal biopsies as indicated, at baseline and 6-monthly follow-up visits.

Pooled Pharyngeal, Rectal, and Urine Specimens for the Point-of-Care Detection of and by Lay Providers in Key Population-Led Health Services in Thailand.

Routine testing for (CT) and (NG) in people with heightened risk is lacking in Thailand. This study aimed to assess the performance of the Cepheid Xpert CT/NG assay, conducted by key population (KP) lay providers, for CT and NG detection on single-site and pooled specimens from the pharynx, rectum, and urine. Between August and October 2019, 188 men who have sex with men and 11 transgender women were enrolled.

The epidemiological impact and cost-effectiveness of key population-led PrEP delivery to prevent HIV among men who have sex with men in Thailand: A modelling study.

Background: Although key populations (KPs), such as men-who-have-sex-with-men (MSM) are disproportionately affected by HIV, many prevention and treatment services are not easily accessible for KP members. To address the needs of KPs, Thailand established pre-exposure prophylaxis (PrEP) service delivery together with and led by KP members. This study determines the epidemiological impact and cost-effectiveness of key population-led (KP-led) PrEP.

Differentiated service delivery for HIV treatment models in Thailand: A cross-sectional assessment of real-world implementation and uptake.

Objectives: First, to describe the antiretroviral therapy (ART) delivery models available in Thailand to understand differentiated service delivery for further service system optimization and expansion of best practices; second, to determine the client characteristics associated with model uptake.

Methods: Across-sectional assessment using secondary data was conducted to describe ART models implemented as routine services at four public hospitals in three major provinces with a high-HIV burden in Thailand. From April to October 2020, ART clients were screened consecutively according to the inclusion criteria: Thai, aged ≥18 years, and on ART for ≥6 months.

Acceptability and retention of the key population-led HIV treatment service for men who have sex with men and transgender women living with HIV in Thailand.

Introduction: In Thailand, where the HIV epidemic is concentrated among key populations (KPs), particularly men who have sex with men (MSM) and transgender women (TGW), an HIV service delivery model tailored to KPs was piloted. This study evaluated the acceptability and retention of clients who accepted and declined the KP-led HIV treatment service.

Methods: A retrospective cohort study was conducted using secondary data from three community-based organizations (CBOs) and three hospitals in Thailand.

Estradiol and Testosterone Concentrations Among Thai Transgender Women in a Transgender-Led, Integrated Gender-Affirming Care and Sexual Health Clinic: A Real-World Analysis.

Purpose: Feminizing hormone therapy (FHT) is used by many transgender women as a pharmacological method to mitigate gender dysphoria. However, information on hormone concentrations among those who use FHT is lacking. We aimed to determine the proportion of Thai transgender women who were using FHT who had hormone concentrations within target ranges in a real-world clinic setting.

Key population-led community-based same-day antiretroviral therapy (CB-SDART) initiation hub in Bangkok, Thailand: a protocol for a hybrid type 3 implementation trial.

Background: Same-day antiretroviral therapy (SDART) initiation, in which people living with HIV (PLHIV) who are antiretroviral therapy (ART)-naïve, willing, and clinically eligible start ART on the same day of HIV diagnosis, has been implemented in several healthcare facilities in Thailand since 2017. This evidence-based practice has demonstrated increased ART uptake, virologic suppression, and retention in care. However, linkage to care gaps exist in community-based organizations (CBOs) in Bangkok whereby as much as 20% of key populations (KP), mainly men who have sex with men and transgender women, living with HIV were lost to follow-up pre-ART initiation.

Long-acting preexposure prophylaxis in low- and middle-income countries: key considerations for implementation.

Purpose Of Review: HIV preexposure prophylaxis (PrEP) is a key tool in ending the HIV epidemic. Long-acting cabotegravir (LA- CAB) phase II/III studies revealed promising efficacy in preventing HIV acquisition. Here, we discuss key considerations for implementing LA-CAB in low- and middle-income countries (LMIC).

Age-Specific Prevalence of Anal and Cervical Human Papillomavirus Infection and High-Grade Lesions in 11 177 Women by Human Immunodeficiency Virus Status: A Collaborative Pooled Analysis of 26 Studies.

Background: Age-specific data on anal, and corresponding cervical, human papillomavirus (HPV) infection are needed to inform female anal cancer prevention.

Methods: We centrally reanalyzed individual-level data from 26 studies reporting HPV prevalence in paired anal and cervical samples by human immunodeficiency virus (HIV) status and age. For women with HIV (WWH) with anal high-grade squamous intraepithelial lesions or worse (HSIL+), we also investigated concurrent cervical cytopathology.

Assessment of U=U understanding, PrEP awareness, HIV risk behaviours and factors associated with low HIV knowledge among users of Hornet, an online dating application for LGBTQ, in Thailand.

Background: Over 50% of HIV infections in Thailand annually occur among men who have sex with men (MSM) and transgender women who use online applications to meet their sexual partners. We conducted a cross-sectional study assessing undetectable=untransmittable (U=U) understanding, pre-exposure prophylaxis (PrEP) awareness, sexual behaviours and factors associated with HIV knowledge among users of Hornet in Thailand.

Methods: From November 2019 to January 2020, a survey was conducted using convenience sampling on Hornet in Thailand.

Evaluation of the integration of telehealth into the same-day antiretroviral therapy initiation service in Bangkok, Thailand in response to COVID-19: a mixed-method analysis of real-world data.

Introduction: Same-day antiretroviral therapy (SDART) initiation has been implemented at the Thai Red Cross Anonymous Clinic (TRCAC) in Bangkok, Thailand, since 2017. HIV-positive, antiretroviral therapy (ART)-naïve clients who are willing and clinically eligible start ART on the day of HIV diagnosis. In response to the first wave of the coronavirus disease 2019 (COVID-19) outbreak in March 2020, telehealth follow-up was established to comply with COVID-19 preventive measures and allow service continuation.

Acceptability and satisfaction towards self-collection for chlamydia and gonorrhoea testing among transgender women in Tangerine Clinic, Thailand: shifting towards the new normal.

Introduction: Provider-collected swabs are an unappealing procedure for many transgender women and may have led to suboptimal rates of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) testing. Self-collection for CT/NG testing is recommended for men who have sex with men. However, the information on acceptability and clinical performance to support a recommendation for transgender women is lacking.

Client and provider preferences for HIV care: Implications for implementing differentiated service delivery in Thailand.

Introduction: Differentiated service delivery (DSD) for antiretroviral therapy (ART) maintenance embodies the client-centred approach to tailor services to support people living with HIV in adhering to treatment and achieving viral suppression. We aimed to assess the preferences for HIV care and attitudes towards DSD for ART maintenance among ART clients and providers at healthcare facilities in Thailand.

Methods: A cross-sectional study using self-administered questionnaires was conducted in September-November 2018 at five healthcare facilities in four high HIV burden provinces in Thailand.

Demedicalisation of HIV interventions to end HIV in the Asia-Pacific.

Despite the challenges to the HIV response in the Asia-Pacific, a demedicalisation of HIV intervention has been demonstrated to be an important strategy to maximise the uptake of HIV prevention tools among key populations in this region. Demedicalisation of HIV interventions translates medical discourse and shifts the paradigm from a disease-focused to a people-centred approach. It also recognises real-life experiences of key populations in the HIV response by empowering them to voice their needs and be at the forefront of the epidemic control.

Go Where the Virus Is: An HIV Micro-epidemic Control Approach to Stop HIV Transmission.

Essentially all HIV transmission is from people living with HIV who are not virally suppressed. An HIV micro-epidemic control approach that differentiates treatment support and prevention services for people living with HIV and their network members according to viral burden could optimize the impact of epidemic control efforts.

Evaluation of a pre-exposure prophylaxis programme for men who have sex with men and transgender women in Thailand: learning through the HIV prevention cascade lens.

Introduction: Men who have sex with men (MSM) and transgender women (TGW) are two key populations (KPs) in Thailand at high risk for HIV. Uptake and scale-up of pre-exposure prophylaxis (PrEP) among them has been slow. We used data from Princess PrEP, Thailand's largest KP-led PrEP programme, to operationalize PrEP service cascades.

Cervical determinants of anal HPV infection and high-grade anal lesions in women: a collaborative pooled analysis.

Background: Cervical cancer screening might contribute to the prevention of anal cancer in women. We aimed to investigate if routine cervical cancer screening results-namely high-risk human papillomavirus (HPV) infection and cytohistopathology-predict anal HPV16 infection, anal high-grade squamous intraepithelial lesions (HSIL) and, hence, anal cancer.

Methods: We did a systematic review of MEDLINE, Embase, and the Cochrane library for studies of cervical determinants of anal HPV and HSIL published up to Aug 31, 2018.

The Association of Gender, Age, Efavirenz Use, and Hypovitaminosis D Among HIV-Infected Adults Living in the Tropics.

Vitamin D, which is important for calcium homeostasis and bone metabolism, has several noncalcemic actions. Low vitamin D levels have been observed in HIV-infected patients from high latitudes, with consequently reduced bone mineral density (BMD), but data from the tropics are scarce. We aimed to determine the prevalence of and risk factors for hypovitaminosis D among HIV-infected patients in the tropics.

Cervical and anal HPV infection: cytological and histological abnormalities in HIV-infected women in Thailand.

Background: Women infected with human immunodeficiency virus (HIV) have higher rates of persistent infection with high-risk human papillomavirus (hr-HPV) and cervical and anal dysplasia. We describe the epidemiology of hr-HPV, and cervical and anal intra-epithelial abnormalities in HIV-infected women in Thailand.

Methods: HIV-infected women aged 18-49 years, either HAART-naïve or -experienced, were enrolled in Bangkok, Thailand.

Advanced liver fibrosis by transient elastography, fibrosis 4, and alanine aminotransferase/platelet ratio index among Asian hepatitis C with and without human immunodeficiency virus infection: role of vitamin D levels.

Background And Aim: Vitamin D insufficiency plays an important role in liver fibrosis in hepatitis C virus (HCV)-infected patients. We assessed liver fibrosis by transient elastography and 25 hydroxy vitamin D [25(OH)D] status in HCV-infected patients, with (HIV/HCV) or without HIV co-infection (HCV) from Thailand.

Methods: Fibrosis stage was defined as mild (< 7.

Ergotism in Thailand caused by increased access to antiretroviral drugs: a global warning.

Ergotism is a toxic condition resulting from overexposure to the ergot compounds produced by various fungi of the genus Claviceps. Traditionally, such exposure was due to ingestion of infected grains, but long-term or excessive use of medications containing ergot derivatives or drug-drug interactions between these medications can result in ergotism. Ergotamine, typically used to treat migraine, has less than 5% bioavailability due to extensive first-pass metabolism by cytochrome P450 3A4 (CYP3A4).

Decline in serum 25 hydroxyvitamin D levels in HIV-HBV-coinfected patients after long-term antiretroviral therapy.

Background: Vitamin D insufficiency plays an important role in the development of fibrosis in chronic liver disease.

Methods: This was a cross-sectional study from Thailand. Liver fibrosis was assessed by transient elastography.

Factors associated with the use of irreversible contraception and continuous use of reversible contraception in a cohort of HIV-positive women.

Background: Effective contraception can be lifesaving by reducing maternal mortality linked to childbirth and unsafe abortion and by reducing vertical and horizontal transmission of HIV, in the case of an HIV-positive woman.

Study Design: This study is a secondary analysis of a prospective cohort study. We assessed factors associated with the use of irreversible contraception and the continuous use of reversible contraception in HIV-positive Thai women.
