Knowledge, attitudes, and practices regarding antiretroviral management, reproductive health, sexually transmitted infections, and sexual risk behavior among perinatally HIV-infected youth in Thailand.

More than 30% of perinatally HIV-infected children in Thailand are 12 years and older. As these youth become sexually active, there is a risk that they will transmit HIV to their partners. Data on the knowledge, attitudes, and practices (KAP) of HIV-infected youth in Thailand are limited. Therefore, we assessed the KAP of perinatally HIV-infected youth and youth reporting sexual risk behaviors receiving care at two tertiary care hospitals in Bangkok, Thailand and living in an orphanage in Lopburi, Thailand. From October 2010 to July 2011, 197 HIV-infected youth completed an audio computer-assisted self-interview to assess their KAP regarding antiretroviral (ARV) management, reproductive health, sexual risk behaviors, and sexually transmitted infections (STIs). A majority of youth in this study correctly answered questions about HIV transmission and prevention and the importance of taking ARVs regularly. More than half of the youth in this study demonstrated a lack of family planning, reproductive health, and STI knowledge. Girls had more appropriate attitudes toward safe sex and risk behaviors than boys. Although only 5% of the youth reported that they had engaged in sexual intercourse, about a third reported sexual risk behaviors (e.g., having or kissing boy/girlfriend or consuming an alcoholic beverage). We found low condom use and other family planning practices, increasing the risk of HIV and/or STI transmission to sexual partners. Additional resources are needed to improve reproductive health knowledge and reduce risk behavior among HIV-infected youth in Thailand.

Outreach strategies to promote HIV testing and linkage-to-care focusing on a young sexual and gender-diverse population in Bangkok, Thailand.

INTRODUCTION: Human Immunodeficiency Virus (HIV) prevalence among young gender-diverse (a wide range of gender identities for people whose gender identity is different from the sex that they were assigned at birth) individuals is high but testing coverage among this key population remains low. We aim to evaluate strategies for outreach, HIV testing, and linkage to proper management in young men-who-have-had-sex-with-men (MSM, homosexual male) and transgender women (TGW) in Bangkok, Thailand. METHODS: The "YM2M outreach program" consisted of two strategies: 1) online platforms (OP) and 2) physical outreach activities (POA). Participant questionnaires were completed on a voluntary basis during outreach activities during 2018-2021. Demographic and behavioral characteristics were assessed for association with HIV positivity. RESULTS: A total of 3,972 homosexual male and TGW participated in the YM2M program: 2,973 by OP and 999 by POA. Of 2,230 participants who reported gender identity, 603/1,392 (43.3%) of OP and 252/985 (25.6%) of POA were gender diverse. Of 631 (21.2%) participants in OP and 970 (97.1%) in POA who underwent testing, 286 (45.3%) in OP and 41 (4.2%) in POA were HIV-positive. The venue reporting highest HIV yield was the Mor-Lam (11.5%). Among those with an HIV-positive test, 175 (61.2%) from OP and 23 (51.1%) from POA were successfully linked to HIV care. The independent factors associated with HIV positive in OP were being youth (adjusted odd ratio (aOR), 0.37; 95%CI 0.16-0.81; P = 0.01) and suspected or confirmed STI (aOR 15.39; 95%CI 7.17-33.03, P<0.01); while those in in POA at Mor-Lam were being gender diverse (aOR, 8.43; 95%CI 1.94-36.62; P<0.01) and reactive syphilis test (aOR, 5.40;95%CI 2.45-11.88; P<0.01). Linkage to pre-exposure prophylaxis (PrEP) among HIV-negative participants was low, 4.9% and 2.6% in OP and POA participants, respectively. CONCLUSIONS: While uptake of HIV testing was higher in POA while OP was more effective in identifying undiagnosed people living with HIV/AIDS and linking them to care. Neither strategy was considered effective in linkage to PrEP.

A pilot program of HIV pre-exposure prophylaxis in Thai youth.

INTRODUCTION: There are gaps in knowledge and experience of antiretroviral pre-exposure prophylaxis (PrEP) delivery in adolescents. METHODS: This pilot study enrolled Thai adolescents 14-20 year-old without HIV who reported risk behaviour. All participants were offered daily tenofovir/emtricitabine (TDF-FTC) and followed for 24 weeks. HIV testing, renal function, bone density scan, and sexually transmitted infection (STI) testing including syphilis serology and urine molecular testing for gonorrhoea and C. trachomatis were performed at baseline and weeks 12 and 24. Adherence was evaluated through intracellular tenofovir diphosphate (TFV-DP) levels in dried blood spots. RESULTS: Of the 61 enrolled adolescents, median age 18.1 (IQR: 14.8-20.9) years, 46 (75.4%) were males and 36 (59%) were MSM. Retention to week 24 was 80.3%. One third (36%) had TFV-DP levels consistent with taking ≥6 pills/week at week 12 and 29% at week 24. The factors associated with taking ≥6 pills/week were being MSM (adjusted odds ratio [aOR]: 53.2, 95% CI: 1.6-1811; p = 0.027), presence of STI at baseline (aOR: 9.4, 95% CI: 1.5-58.5; p = 0.016), and self-report of decreased condom use while taking PrEP (aOR: 8.7, 95% CI: 1.4-56.6; p = 0.023). 31% had an STI at baseline and this declined to 18% at week 24. No renal or bone toxicity was observed and there were no HIV seroconversions. CONCLUSIONS: Daily oral PrEP with FTC-TDF in high-risk Thai adolescents is feasible, accepted, well-tolerated, and had no increased risk compensation; however, low adherence was a major challenge. Adolescent-specific PrEP strategies including long-acting modalities are needed for successful HIV prevention.

Development of a diagnosis disclosure model for perinatally HIV-infected children in Thailand.

While disclosure of HIV status to perinatally HIV-infected children has become an increasingly important clinical issue, specific disclosure guidelines are lacking. We developed a pediatric HIV diagnosis disclosure model to support caretakers. All HIV-infected children greater than 7-years-old at two participating hospitals in Bangkok, Thailand, and their caretakers, were offered disclosure according to the 4-step protocol: (1) screening; (2) readiness assessment; (3) disclosure; and (4) follow-up. Disclosure occurred after agreement of both providers and caretakers. Among 438 children who were screened, 398 (89%) were eligible. Readiness assessment was completed for 353 (91%) of eligible children and 216 (61%) were determined ready. Disclosure was done for 186 children. The mean age at eligibility screening was 10.5 years (range: 6.8-15.8 years); the mean age at disclosure was 11.7 years (range: 7.6-17.7 years). The mean duration between eligibility screening and disclosure was 15.2 months. There were no significant negative behavioral or emotional outcomes reported in children following disclosure. This HIV diagnosis disclosure model was feasible to implement and had no negative outcomes. As the time for preparation process was over 1 year for most cases, the disclosure process can be initiated as early as age 7 to allow enough time for disclosure to be completed by the age of adolescence.

Disclosure of HIV status to sexual partners among perinatally HIV-infected youth in Thailand.

Data regarding disclosure of HIV status to sexual partners among perinatally acquired HIV-infected (PHIV) youth are limited, particularly from Asian countries. This cross-sectional study assessed the patterns of, attitudes about, and factors associated with HIV disclosure to sexual partners among PHIV youth aged 15-24 years who attended a pediatric HIV clinic in Thailand. Participants were interviewed using a semi-structured questionnaire designed to elicit demographic and sexual behavior information. Those who had sexual partners were queried about their relationship and HIV status disclosure. Reasons to disclose or not to disclose were assessed accordingly. Among the 51 (44.4%) youth who had sexual partners, 55.8% had steady partners, 45.1% did not always use condoms, and 41.2% disclosed their HIV status. Reasons to disclose included trust and concern about the risk of infection to their partners. Reasons not to disclose included fear of rejection and stigmatization, and not knowing how to disclose. Most youth reported a need for disclosure-related guidance. Knowing their sexual partner's HIV status was the only independent factor associated with disclosure (aOR 14.6; 95% CI 2.8-75.4). This study demonstrates a high rate of unsafe sex and a low rate of partner disclosure in PHIV youth, and highlights the need for a comprehensive guideline for HIV disclosure to sexual partners.

Developmental screening by the Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS) in HIV- infected children.

Bayley Scales of Infant Development (BSID) is considered to be a standard test for child development. The test requires experienced evaluator and is time consuming; therefore, it is not easy to apply in busy clinic. The Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS) is an easy assessment method that has been demonstrated to correlate with BSID in many studies among normal and developmental delayed children, including in HIV-infected infants. We created a pilot system of CAT/CLAMS assessment applied to 16 HIV-infected infants ages 12-34 months. They were all in the normal range score of developmental quotient (DQ). However, longitudinal follow-up by CAT/CLAMS assessment is needed in these HIV-infected children. When DQ score is below 70 (assuming to be delayed development), the child should be evaluated by BSID. In this way delayed development can be screened easily and early developmental stimulation program can be implemented appropriately.

Diagnosis disclosure in HIV-infected Thai children.

BACKGROUND: Increasing number of children with perinatally acquired HIV-infection are now surviving into school age and adolescence. Disclosure of diagnosis to these children has become an important clinical issue. Clinical reports and studies from other countries suggest that a significant number of these children have not been told of their HIV status. The objective of this study was to assess diagnosis disclosure status of perinatally acquired HIV-infected Thai children. MATERIAL AND METHOD: Primary caregivers of 96 HIV-infected children aged 5 years and older were interviewed to assess the child disclosure status and the caregivers reasons to disclose or not to disclose the diagnosis to the child. The disclosed children were also interviewed to assess perception of their illness. RESULTS: Nineteen of 96 children (19.8%) had been told of their HIV diagnosis by their caregivers. The mean age of the disclosed children was 9.6 years. Eighty-four percent of the disclosed children reported perception of their illness as having HIV infection or AIDS. Common reasons for non-disclosing were concerns that the child was too young, that the child might be psychologically harmed, and that the child could not keep the secret. Of 77 non-disclosing caregivers, 54 reported that they plan to disclose HIV status to the children in the future. CONCLUSION: This study demonstrates that diagnosis disclosure was made in only 1/5 of HIV-infected children, and that most of the caregivers were reluctant in disclosing serostatus to the child. Development of an appropriate guideline for assisting the caregivers and the children to deal with the difficult disclosure process is needed.
