Abstract
OBJECTIVE Cryptococcosis predominantly presents as a meningoencephalitis in Thailand. Early and expeditious diagnosis is essential for reducing both mortality and morbidity associated with cryptococcal meningitis. We aim to define and establish the diagnostic performances between the benchmark commercially available diagnostic kit (CrAg® LFA) and the large-scale prototype of an inexpensive in-house immunochromatographic test (ICT) based on monoclonal antibody (MAb) 18B7. METHODS We have developed the large-scale prototype for the rapid detection of cryptococcal polysaccharide antigens by utilizing a single antibody sandwich ICT format employing MAb 18B7, which is highly specific to Cryptococcus neoformans glucuronoxylomannan (GXM) antigens. An in-house MAb18B7 ICT was manufactured in accordance with industry standards under the control of the International Organization for Standardization (ISO) 13485. RESULTS The diagnostic sensitivity, specificity, and accuracy for the in-house MAb 18B7 ICT were 99.10%, 97.61%, and 97.83%, respectively. The agreement kappa (κ) coefficient was 0.968 based on the retrospective evaluation of 580 specimens from patients living in northern Thailand with clinically suspected cryptococcosis. CONCLUSION The data suggest that this in-house MAb 18B7 ICT will be highly beneficial for addressing the issue of cryptococcal infection in Thailand. Moreover, it is anticipated that this inexpensive ICT can play a pivotal role in various global strategies aimed at eradicating cryptococcal meningitis among individuals living with HIV by 2030.

Toledo LDSG, Almeida AIS, Bastos FI. Mapping projects for expanding rapid HIV testing in key populations, Brazil, 2004-2021. CAD SAUDE PUBLICA 2024; 40:e00182323. [PMID: 38775573 PMCID: PMC11105351 DOI: 10.1590/0102-311xen182323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 01/18/2024] [Accepted: 01/22/2024] [Indexed: 05/25/2024] Open
Abstract
The HIV/AIDS epidemic remains a persistent and real issue, especially in key populations such as men who have sex with men (MSM), travestis and transgender persons. Projects for expanding rapid HIV testing are strategic initiatives aimed at the earliest possible identification of individuals' serological status and thus early treatment, screening of sex partners, and upscaling of preventive actions to interrupt the transmission chain. This study thus maps, describes, and systematizes the projects for expanding rapid HIV testing implemented from 2004 to 2021 in Brazil, highlighting the on-going contribution of civil society organizations and discussing the interoperability and cooperation resulting from public governance processes. We selected 67 documents for analysis, including 30 scientific publications retrieved from electronic databases and 37 documents produced by government institutions and nongovernmental organizations (NGOs). Find Out (Fique Sabendo), I Want to Get Tested (Quero Fazer), The Time is Now (A Hora É Agora), Live Better Knowing (Viva Melhor Sabendo), and Live Better Knowing Young (Viva Melhor Sabendo Jovem) were the projects mapped. Results show that the projects have used strategies adapted to the key population, such as mobile testing units, peer education, and innovative community engagement approaches. Such actions were enabled by effective cooperation and interoperability between participating stakeholders, especially NGOs.

A comparative study of transgender women accessing HIV testing via face-to-face and telemedicine services in Chiang Mai, Thailand during the COVID-19 pandemic and their risk of being HIV-positive. BMC Public Health 2023; 23:2161. [PMID: 37925430 PMCID: PMC10625702 DOI: 10.1186/s12889-023-17124-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Accepted: 11/01/2023] [Indexed: 11/06/2023] Open
Abstract
BACKGROUND Due to the restricted availability of health services in Thailand, there are still some transgender women (TGW) who do not have access to HIV counseling and testing. Telehealth, which is accessible to individuals who are reluctant to undergo face-to-face interviewing, played an especially important role during the COVID-19 epidemic. The objectives of this study are to compare the characteristics, pattern of accessing HIV testing, and the HIV-positive rates of TGW between the face-to-face and telemedicine services. METHODS We conducted a cross-sectional study to compare the access to HIV testing and the HIV-positive rates among TGW via face-to-face service and telemedicine services and examined the influence of potential associated factors on the risk of being HIV-positive. RESULTS Of the 637 TGW participants, 26 (4.1%) were HIV-positive. Accessing the telemedicine service increased in the third and fourth COVID-19 waves (28.1% in the first and second vs. 71.9% in the third and fourth). There was no difference in the risk of being HIV-positive between the types of service. Having sex work experience (adjusted odds ratio (aOR) = 5.92; 95% confidence interval (CI): 1.57-22.30) and either never having been or tested more than 1 year ago were independently significantly associated with a higher risk of being HIV-positive (aOR = 4.05; 95% CI: 1.11-14.77). CONCLUSION The telemedicine service became more popular among TGW during the COVID-19 pandemic and was not related to a higher risk of being HIV-positive. Moreover, it proved to be an effective alternative channel to access HIV testing, especially for intravenous drug users. Sex work experience and irregular HIV testing are key risk factors for HIV infection in TGW seeking either the telemedicine or face-to-face service.

JMIR Public Health Surveill 2023; 9:e43394. [PMID: 36795477 PMCID: PMC9982722 DOI: 10.2196/43394] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 01/06/2023] [Accepted: 01/11/2023] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND Mobile voluntary counseling and testing (VCT) for HIV has been carried out to improve the targeting of at-risk populations and HIV case detection for men who have sex with men (MSM). However, the HIV-positive detection rate using this screening strategy has declined in recent years. This may imply unknown changes in risk-taking and protective features jointly influencing the testing results. These changing patterns in this key population remain unexplored. OBJECTIVE The aim of this study was to identify the nuanced group classification of MSM who underwent mobile VCT using latent class analysis (LCA), and to compare the difference in characteristics and testing results between subgroups. METHODS A cross-sectional research design and purposive sampling were applied between May 21, 2019, and December 31, 2019. Participants were recruited by a well-trained research assistant through social networking platforms, including the most popular instant messenger app Line, geosocial network apps dedicated to MSM, and online communities. Mobile VCT was provided to participants at an assigned time and place. Demographic characteristics and risk-taking and protective features of the MSM were collected via online questionnaires. LCA was used to identify discrete subgroups based on four risk-taking indicators-multiple sexual partners (MSP), unprotected anal intercourse (UAI), recreational drug use within the past 3 months, and history of sexually transmitted diseases-and three protective indicators-experience of postexposure prophylaxis, preexposure prophylaxis use, and regular HIV testing. RESULTS Overall, 1018 participants (mean age 30.17, SD 7.29 years) were included. A three-class model provided the best fit. Classes 1, 2, and 3 corresponded to the highest risk (n=175, 17.19%), highest protection (n=121, 11.89%), and low risk and low protection (n=722, 70.92%), respectively. Compared to those of class 3, class 1 participants were more likely to have MSP and UAI within the past 3 months, to be ≥40 years of age (odds ratio [OR] 2.197, 95% CI 1.357-3.558; P=.001), to have HIV-positive results (OR 6.47, 95% CI 2.272-18.482; P<.001), and a CD4 count ≤349/μL (OR 17.50, 95% CI 1.223-250.357; P=.04). Class 2 participants were more likely to adopt biomedical preventions and have marital experience (OR 2.55, 95% CI 1.033-6.277; P=.04). CONCLUSIONS LCA helped derive a classification of risk-taking and protection subgroups among MSM who underwent mobile VCT. These results may inform policies for simplifying the prescreening assessment and more precisely recognizing those who have higher probabilities of risk-taking features but remain undiagnosed targets, including MSM engaging in MSP and UAI within the past 3 months and those ≥40 years old. These results could be applied to tailor HIV prevention and testing programs.

Abstract
PURPOSE OF REVIEW This review summarizes recently published research on sexually transmitted infections (STIs) and sexually transmitted diseases (STDs) among men who have sex with men (MSM) in Asia, covering four main areas: prevalence and consequences of STIs/STDs, factors associated with STI risk, strategies and measures of STI prevention, challenges in the prevention of SITs. RECENT FINDINGS Studies show that STIs among Asian MSM are still prevalent, with the prevalence of STIs varying slightly from country to country. In addition to the number of sexual partners, frequency of condom use, high-risk sexual behaviors, the influence of Confucianism, law, and COVID-19 are also related to STI risk. Social stigma, weak health systems, lack of funding and policy support are the current challenges for STIs prevention. SUMMARY In the future, new media technologies are encouraged to be used to enhance education and reduce stigma and discrimination against MSM and STIs. Expanding STI screening, strengthening STI knowledge propaganda and education among MSM population, and providing necessary counseling and medical services are main strategies in STI prevention. It is also important to strengthen STI awareness and policy support at the national level.

Abstract
Although HIV pre-exposure prophylaxis (PrEP) is free in Thailand, many transgender women discontinue taking it after initiation. We determined the loss to follow-up (LTFU) rate of transgender women who initiated PrEP at the Mplus Foundation, Chiang Mai, Thailand, and identified associated risk factors using Cox proportional hazard models. Of 235 participants who initiated PrEP, 59 (55%) out of 108 remaining participants had reactive syphilis. The LTFU rate at 6 months was 38% (95% confidence interval [CI]: 29-48%). Multivariable analysis indicates that LTFU is independently associated with age ≥ 26 years old (adjusted hazard ratio [aHR] = 2.09; 95% CI: 1.06-4.14) and reactive syphilis (aHR = 1.98; 95% CI:1.01-3.88). Delayed appointment scheduling by the PrEP providers and the syphilis clinic was associated with transgender women having reactive syphilis, and the lockdown policy during the COVID-19 pandemic might have influenced them to discontinue PrEP and their subsequent LTFU.

Increased Work Experience Associated with Less Stigmatizing Attitudes towards People Living with HIV among Thai Healthcare Personnel. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18189830. [PMID: 34574754 PMCID: PMC8465955 DOI: 10.3390/ijerph18189830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 09/01/2021] [Accepted: 09/13/2021] [Indexed: 11/17/2022]
Abstract
HIV-related stigma in health facilities has been suggested as a primary target for HIV-related stigma reduction. The objective of this study was to describe negative attitudes among Thai healthcare personnel (HCP) toward PLHIV. This nationwide probability sampled survey was conducted in 2019 in 12 provinces in Thailand and Bangkok, the capital. Participants were considered to have stigmatizing attitudes toward PLHIV if they had a stigmatizing view in response to at least one of the four questions. Eighty-two percent of the 3056 respondents had at least one stigmatizing attitude. Younger HCP, ages < 30 (AOR = 1.60; 95%CI: 1.18–2.18) and 30–39 (AOR = 1.60; 95%CI: 1.21–2.12) were more likely to have stigmatizing attitudes towards PLHIV compared to those aged 50 and older. Being support staff, support-clinical (AOR = 1.89; 95%CI: 1.44–2.49) and support-nonclinical (AOR = 1.71; 95%CI: 1.24–2.36) as opposed to professional staff also increased the likelihood of having stigmatizing attitudes. Stigma was also more likely to be present in HCPs who did not work at HIV-focused clinics (AOR = 1.97; 95%CI: 1.57–2.48). HCP who had more work experience, especially related to PLHIV care, were less likely to have stigmatizing attitudes. These personnel could be good peer educators or role models for a stigma reduction campaign within their healthcare facilities.
