RESUMEN
Women living with HIV/AIDS (WLHA) encounter numerous challenges, such as stigma and gender disparities, that hinder their access to care, especially in patriarchal societies like Vietnam. We developed a hybrid intervention with online and offline (in-person) components to empower WLHA in Vietnam. The intervention was pilot tested with 91 WLHA in Hanoi. During baseline and 4-month, study investigators delivered two in-person sessions, one Zoom session, and 15 weeks of Zalo (social media platform) discussions to enhance positive coping strategies, treatment utilization and adherence, and engagement of support from family and peers. The participants continued their Zalo discussions from 4-month to 6-month without investigators' involvement. Intervention outcomes, including active coping and perceived barriers to care, were evaluated at baseline, 4-, and 6-month surveys. Mixed-effects regression models showed that the participants' active coping significantly increased from baseline (50.5 ± 9.4) to 4-month (53.8 ± 6.2; p = 0.0001), although there was a slight decrease at 6-month (52.8 ± 7.2), the change from 4-month to 6-month was not significantly significant (p = 0.3256). There was a significant reduction in participants' perceived barriers to care, from 19.8 ± 5.2 at baseline to 17.4 ± 5.2 at 4-month (p < 0.0001), which remained stable at 17.8 ± 4.3 at 6-month (p < 0.0001 compared to baseline). This intervention presents a promising model to empower WLHA in Vietnam and potentially in similar global contexts. Future interventions could benefit from leveraging natural peer leaders and adopting a more person-centered approach to meet WLHA's varying needs.
RESUMEN
BACKGROUND: Neisseria gonorrhoeae (NG) and Chlamydia trachomatis (CT) disproportionately affect men who have sex with men (MSM). Data on the prevalence, anatomical distribution, and correlates of NG and CT infections among MSM in Vietnam are limited. METHODS: Between July 2017 and April 2019, MSM 16 years or older without HIV were enrolled into an observational cohort study. Baseline data, including sociodemographics, sexual behavior, and HIV status, were collected. Testing for NG and CT were performed on urine, rectal, and pharyngeal specimens. Multivariate logistic regression models identified factors associated with NG and CT infections at baseline. RESULTS: In total, 1489 participants underwent NG/CT testing. The median age was 22 years (interquartile range, 20-26 years). There were 424 (28.5%) NG or CT infections: 322 (21.6%) with CT and 173 (11.6%) with NG. Rectal infections were most common for CT (73.9%), whereas pharyngeal infections were most common for NG (70.5%). Independent risk factors for CT or NG infection included ≥2 sex partners in the prior month (adjusted odds ratio [aOR], 2.04; 95% confidence interval [CI], 1.44-2.91), condomless anal sex (aOR, 1.44; 95% CI, 1.12-1.86), and meeting sex partners online (aOR, 1.35; 95% CI, 1.03-1.76). Recent genitourinary or rectal symptoms were not associated with infections. CONCLUSIONS: The overall and extragenital prevalences of NG and CT infections were high within this sample of young MSM without HIV in Hanoi. Testing limited to urethral specimens would have missed nearly three-quarters of CT and NG infections, supporting the need for routine testing at multiple anatomic sites.

Background: People who inject drugs are subjected to great stigmatization in many parts of the world. How they deal with stigma is closely linked to how stigma means to them. Understanding the strategies individuals employ to cope with these negative attitudes and what resources they mobilize in this process gives useful insights for clinical work and policy development. Methods: We conducted 12 months of field observation in 2017 and 2018 and 54 in-depth interviews with people who inject drugs in Haiphong, Vietnam. Grounded theory underpinned our sampling and data analysis. Results: The strategies participants used to manage stigma were both information and tension management. Many participants not only concealed their drug use but actively cultivated a pro-social image based on Vietnamese cultural virtues such as selflessness, hard work or harmonious living with others. Participants withdrew from social relationships to distance themselves from the stereotype of a money-begging drug user. They used techniques of neutralization to emphasize their good character and reframe their drug-related issues in a different light in order to negotiate their social status with their interlocutors. Conclusion: People who inject drugs endorse the same social values and aspirations as nonusers. A good support structure and resources could help them to cope more effectively with stigma.
RESUMEN
BACKGROUND: Heroin use continues to drive HIV transmission in Vietnam, but methamphetamine and alcohol use are growing rapidly and, as in other countries, polysubstance use is widespread. The objective of this study was to understand the interplay between heroin, methamphetamine, and alcohol use among people with opioid use disorder (OUD) and HIV in Vietnam. METHODS: We conducted 44 in-depth, face-to-face qualitative interviews with people with OUD and HIV who participated in the BRAVO trial of buprenorphine versus methadone in five Vietnam HIV clinics. Interviews probed participants' experiences of heroin, methamphetamine, and alcohol use and their interplay with HIV/OUD treatment. Interviews were professionally transcribed and analyzed using a thematic analysis approach. RESULTS: Of 44 participants interviewed 42 were male, on average 38.8 years of age, with 30 reporting a history of methamphetamine use and 33 reporting a history of alcohol use. Several themes emerged: 1) Methamphetamine and alcohol were perceived to have lower addiction potential than heroin 2) Social settings were key facilitators of alcohol and methamphetamine use 3) Some participants, but not all, used methamphetamine to help quit heroin 4) Consuming alcohol blunted the effects of heroin, while paradoxically serving as a catalyst for heroin use 5) Use of methamphetamine was perceived by many participants to be incompatible with treatment for HIV. CONCLUSIONS: Participant experiences reflected a significant impact of polysubstance use on treatment of HIV and OUD. Patterns of polysubstance use are subject to common preconceptions of alcohol and methamphetamine as having a low addictive potential, and these substances are deeply enmeshed in the social life of many people with OUD in Vietnam. Interventions to address complex social norms and potential harms of polysubstance use are urgently needed as the population of people receiving medication for OUD (MOUD) increases in Vietnam and globally. TRIAL REGISTRATION: BRAVO - NCT01936857 , September 2013.

BACKGROUND: Little is known about patient characteristics that contribute to initiating antiretroviral therapy (ART) and achieving viral suppression among HIV people with opioid use disorder in Vietnam. The primary objective of this analysis was to evaluate associations between participant characteristics and the critical steps in the HIV care continuum of ART initiation and HIV viral suppression among people with opioid use disorder and HIV in Vietnam. METHODS: We assessed baseline participant characteristics, ART status, and HIV viral suppression (HIV RNA PCR < 200 copies/mL) enrolled in a clinical trial of HIV clinic-based buprenorphine versus referral for methadone among people with opioid use disorder in Vietnam. We developed logistic regression models to identify characteristics associated with ART status and HIV viral suppression. RESULTS: Among 283 study participants, 191 (67.5%) were prescribed ART at baseline, and 168 of those on ART (90%) were virally suppressed. Years since HIV diagnosis (aOR = 1.12, 95% CI 1.06, 1.19) and being married (aOR = 2.83, 95% CI 1.51, 5.34) were associated with an increased likelihood of current prescription for ART at baseline. Greater depression symptoms were negatively associated with receipt of ART (aOR = 0.97, 95% CI = (0.94, 0.9963)). In the HIV suppression model, once adjusting for all included covariates, only receipt of ART was associated with viral suppression (aOR = 25.9, 95% CI = (12.5, 53.8). In bivariate analyses, methamphetamine was negatively correlated with ART prescription (p = 0.07) and viral suppression (p = 0.08). CONCLUSION: While fewer than 90% of participants had received ART, 90% of those on ART had achieved HIV viral suppression at baseline, suggesting that interventions to improve uptake of ART in Vietnam are essential for achieving UNAIDS 90-90-90 goals in people who use heroin in Vietnam. Social determinants of health associated with ART and HIV viral suppression suggest that social support may be a key to facilitating both of these steps in the HIV care continuum.

Many men who have sex with men (MSM) in low and middle income countries search for male sexual partners via social media in part due to societal stigma and discrimination, yet little is known about the sexual risk profiles of MSM social media users. This cross-sectional study investigates the prevalence of social media use to find male sex partners in Hanoi, Vietnam and examines associations between social media use and sociodemographic and behavioral characteristics, including levels of internalized, perceived and enacted stigma, high-risk sexual behaviors, and HIV testing. 205 MSM were recruited from public venues where MSM congregate as well as through snowball sampling and completed an anonymous survey. MSM who found their male sexual partners using social media in the last year were more likely to have completed a university or higher degree (aOR 2.6; 95% CI 1.2-5.7), experience high levels of MSM-related perceived stigma (aOR 3.0; 95% CI 1.1-8.0), and have more than ten lifetime male sexual partners (aOR 3.2; 95% CI 1.3-7.6) compared to those who did not use social media. A niche for social media-based interventions integrating health and stigma-reduction strategies exists in HIV prevention programs for MSM.

Little is known about the age of onset of sexual and drug risk and their association with complex patterns of recent drug use among male sex workers (MSW) in a developing country, such as Vietnam. The aim of this study was to determine whether latent class analysis (LCA) would aid in the detection of current individual and polydrug use combinations to predict how different trajectories of sexual and drug initiation contribute to different patterns of current illicit drug use. Data were collected from a cross-sectional survey administered to young MSWs between 2010 and 2011 in Vietnam (N = 710). LCA clustered participants into recent drug use groups, incorporating both the specific types and overall count of different drugs used. Men reported drug use within a 1 month period from an 11-item drug use list. LCA identified three distinct drug use classes: (1) alcohol use, (2) alcohol and tobacco use, and (3) high polydrug use. The current drug use classes are associated with sex worker status, housing stability, income level, educational attainment, marital status, sexual identity, and sexual preferences. High levels of drug use are strongly associated with being a recent sex worker, not having recent stable housing, higher than median income, more than a high school education, less likely to be currently in school and more likely to have non-homosexual preferences and heterosexual partners. An event history analysis approach (time-event displays) examined the timing of the age of onset of drug and sexual risks. Early ages of drug and sexual initiation are seen for all three classes. High current drug users show earlier onset of these risks, which are significantly delayed for moderate and low current drug users. LCA incorporating an overall count of different drugs detected three distinct current drug use classes. The data illustrates that the complexity of drug factors that must be accounted for, both in advancing our epidemiological understanding of the complexity of drug use and the use of drug and sexual risk initiation data to predict current drug use subtypes among high-risk populations.

Drawing on the changing landscape of responses to HIV in Vietnam, this article describes the key players and analyzes the relationships between global players and local interests, including both the omnipresent state and an emerging civil society presence. We discuss the critical importance of timing for policy intervention and the role of health policy in shaping the broader social terrain. The interventions of external actors such as the US President's Emergency Plan for AIDS Relief (PEPFAR) and the Global Fund were instrumental in improving both policies and programs at a critical juncture, when the national responses to the epidemic had been ineffective. At the same time, those global interventions met resistance and led to unintended consequences, both welcome and unwelcome. Furthermore, the looming specter of donor withdrawal and the very gradually emerging national ownership raise many questions about capacity for scale-up and sustainability of the significant achievements to date. Further monitoring and in-depth analysis of the Vietnamese responses to the HIV epidemic in the next few years or so, we contend, have the potential to provide unique insights into the challenges faced by developing countries caught in the complex webs of health politics and policies at both the global and the national levels.

Vietnam has a concentrated HIV epidemic, with the highest HIV prevalence being observed among people who inject drugs (PWID). Based on its experience scaling-up robust HIV interventions, Vietnam aims to further strengthen its response by harnessing the preventive benefits of antiretroviral therapy (ART). Mathematical modelling suggests that prioritizing key populations for earlier access to ART, combined with other prevention interventions, may have significant impact on the epidemic, cost-effectively reducing new HIV infections and deaths. Pilot studies are being conducted to assess feasibility and acceptability of expansion of HIV testing and counselling (HTC) and early ART among key populations and to demonstrate innovative service delivery models to address challenges in uptake of services across the care cascade. Earlier access of key populations to combination prevention interventions, combined with sustained political commitment and supportive environment for key populations, are essential for maximum impact of ART on the HIV epidemic in Vietnam.

INTRODUCTION: Compulsory drug rehabilitation is a major governmental response to illicit drug use in Vietnam and other countries in Asia. Long-term compulsory rehabilitation is associated with negative health, social and economic outcomes. The transition to community-based services for people released from compulsory drug rehabilitation has been problematic not only in Vietnam. This study utilized the WHO Health System Building Blocks Framework to examine the opportunities and challenges for people with substance use disorders (SUD) who are released from compulsory drug rehabilitation back into the community. METHODS: Between October 2021 and August 2022, we interviewed people with SUD who had recently returned from or were preparing to leave compulsory drug rehabilitation (n = 25), their family members (n = 20) and professionals working in the field of drug rehabilitation (n = 28) across three cities in Vietnam. Additionally, we conducted a review of policy documents to complement the interview data. RESULTS: The study identified opportunities and challenges within Vietnam's drug rehabilitation system concerning leadership and governance, financing, workforce, information systems and service delivery for people with SUD. Key opportunities include a legal framework that emphasizes community-based support for people with SUD, a government-funded national network of lay social workers, and ongoing efforts to connect people to community-based services. We found significant challenges caused by the lack of clear instructions for implementing supportive policies, inadequate funding for community-based services, persisting stigma from providers towards people with SUD and unavailability of community-based drug treatment other than methadone. CONCLUSION: Vietnam continues with compulsory drug rehabilitation yet endorses recovery-oriented policies to address substance use issues. Substantial challenges hinder the effective implementation of these policies. Our study recommends reinforcing existing policies and enhancing recovery-oriented community-based services by improving the quality of data collection, building capacity of lay social workers who facilitate linkages to services and expanding community-based drug treatment options.

Background: The COVID-19 pandemic has revealed significant challenges in disease forecasting and in developing a public health response, emphasizing the need to manage missing data from various sources in making accurate forecasts. Objective: We aimed to show how handling missing data can affect estimates of the COVID-19 incidence rate (CIR) in different pandemic situations. Methods: This study used data from the COVID-19/SARS-CoV-2 surveillance system at the National Institute of Hygiene and Epidemiology, Vietnam. We separated the available data set into 3 distinct periods: zero COVID-19, transition, and new normal. We randomly removed 5% to 30% of data that were missing completely at random, with a break of 5% at each time point in the variable daily caseload of COVID-19. We selected 7 analytical methods to assess the effects of handling missing data and calculated statistical and epidemiological indices to measure the effectiveness of each method. Results: Our study examined missing data imputation performance across 3 study time periods: zero COVID-19 (n=3149), transition (n=1290), and new normal (n=9288). Imputation analyses showed that K-nearest neighbor (KNN) had the lowest mean absolute percentage change (APC) in CIR across the range (5% to 30%) of missing data. For instance, with 15% missing data, KNN resulted in 10.6%, 10.6%, and 9.7% average bias across the zero COVID-19, transition, and new normal periods, compared to 39.9%, 51.9%, and 289.7% with the maximum likelihood method. The autoregressive integrated moving average model showed the greatest mean APC in the mean number of confirmed cases of COVID-19 during each COVID-19 containment cycle (CCC) when we imputed the missing data in the zero COVID-19 period, rising from 226.3% at the 5% missing level to 6955.7% at the 30% missing level. Imputing missing data with median imputation methods had the lowest bias in the average number of confirmed cases in each CCC at all levels of missing data. In detail, in the 20% missing scenario, while median imputation had an average bias of 16.3% for confirmed cases in each CCC, which was lower than the KNN figure, maximum likelihood imputation showed a bias on average of 92.4% for confirmed cases in each CCC, which was the highest figure. During the new normal period in the 25% and 30% missing data scenarios, KNN imputation had average biases for CIR and confirmed cases in each CCC ranging from 21% to 32% for both, while maximum likelihood and moving average imputation showed biases on average above 250% for both CIR and confirmed cases in each CCC. Conclusions: Our study emphasizes the importance of understanding that the specific imputation method used by investigators should be tailored to the specific epidemiological context and data collection environment to ensure reliable estimates of the CIR.

BACKGROUND: Evidence-based interventions (EBIs) often address normative behaviors. If a behavior is also common among clinicians, they may be skeptical about the necessity or effectiveness of an EBI. Alternatively, clinicians' attitudes and behaviors may be misaligned, or they may lack the knowledge and self-efficacy to deliver the EBI. Several EBIs address unhealthy alcohol use, a common and often culturally acceptable behavior. But unhealthy alcohol use may be particularly harmful to people with HIV (PWH). Here, we present an implementation trial using an experiential implementation strategy to address clinicians' knowledge, attitudes, and behaviors. Clinicians receive the experiential intervention before they begin delivering an evidence-based brief alcohol intervention (BAI) to PWH with unhealthy alcohol use. METHODS: Design: In this hybrid type 3 implementation-effectiveness cluster randomized controlled trial, ART clinics (n = 30) will be randomized 1:1 to facilitation, a flexible strategy to address implementation barriers, or facilitation plus the experiential brief alcohol intervention (EBAI). In the EBAI arm, clinicians, irrespective of their alcohol use, will be offered the BAI as experiential learning. EBAI will address clinicians' alcohol-related attitudes and behaviors and increase their knowledge and confidence to deliver the BAI. PARTICIPANTS: ART clinic staff will be enrolled and assessed at pre-BAI training, post-BAI training, 3, 12, and 24 months. All PWH at the ART clinics who screen positive for unhealthy alcohol use will be offered the BAI. A subset of PWH (n = 810) will be enrolled and assessed at baseline, 3, and 12 months. OUTCOMES: We will compare implementation outcomes (acceptability, fidelity, penetration, costs, and sustainability) and effectiveness outcomes (viral suppression and alcohol use) between the two arms. We will assess the impact of site-level characteristics on scaling-up the BAI. We will also evaluate how experiencing the BAI affected clinical staff's alcohol use and clinic-level alcohol expectations in the EBAI arm. DISCUSSION: This trial contributes to implementation science by testing a novel strategy to implement a behavior change intervention in a setting in which clinicians themselves may engage in the behavior. Experiential learning may be useful to address normative and difficult to change lifestyle behaviors that contribute to chronic diseases.

BACKGROUND: In Vietnam and other global settings, men who have sex with men (MSM) have become the population at greatest risk of HIV infection. Although HIV pre-exposure prophylaxis (PrEP) has been implemented as a prevention strategy, PrEP outcomes may be affected by low persistence and adherence among MSM with unhealthy alcohol use. MSM have a high prevalence of unhealthy alcohol use in Vietnam, which may affect PrEP outcomes. METHODS: Design: We will conduct a two-arm hybrid type 1 effectiveness-implementation randomized controlled trial of a brief alcohol intervention (BAI) compared to the standard of care (SOC) at the Sexual Health Promotion (SHP) clinic Hanoi, Vietnam. PARTICIPANTS: Sexually active MSM (n=564) who are newly initiating PrEP or re-initiating PrEP and have unhealthy alcohol use will be recruited and randomized 1:1 to the SOC or BAI arm. A subgroup of participants (n=20) in each arm will be selected for longitudinal qualitative interviews; an additional subset (n=48) in the BAI arm will complete brief quantitative and qualitative interviews after completion of the BAI to assess the acceptability of the intervention. Additional implementation outcomes will be assessed through interviews with clinic staff and stakeholders (n=35). INTERVENTION: Study participants in both arms will receive standard care for PrEP clients. In the BAI arm, each participant will receive two face-to-face intervention sessions and two brief booster phone sessions, based on cognitive behavioral therapy and delivered in motivational interviewing informed style, to address their unhealthy alcohol use. OUTCOMES: Effectiveness (PrEP and alcohol use) and cost-effectiveness outcomes will be compared between the two arms. Intervention implementation outcomes (acceptability, feasibility, adoption) will be assessed among MSM participants, clinic staff, and stakeholders. DISCUSSION: This proposed trial will assess an alcohol intervention for MSM with unhealthy alcohol use who initiate or re-initiate PrEP, while simultaneously preparing for subsequent implementation. The study will measure the effectiveness of the BAI for increasing PrEP persistence through reducing unhealthy alcohol use in a setting where excessive alcohol consumption is a normative behavior. If effective, implementation-focused results will inform future scale-up of the BAI in similar settings. TRIAL REGISTRATION: NCT06094634 on clinicaltrials.gov. Registered 16 October 2023.

BACKGROUND: Depression is a common mental disorder that significantly contributes to the global burden of disease. Studies have consistently reported that migrant workers experience higher levels of depressive symptoms, especially women. AIMS: This study aimed to examine the mediation role of sexual self-efficacy on the relationship between psychological wellbeing, and depressive symptoms among young female migrant workers in Vietnam's industrial zones. METHODS: A cross-sectional study was conducted among 1061 female migrant workers aged 18 to 29 from January to November 2020 in Hanoi, Vietnam. Anonymous interview questionnaires were used to collect data on demographic characteristics, psychosocial wellbeing (PWB), sexual self-efficacy, and depressive symptoms. Mediation analysis was conducted to explore the mediation effect of sexual self-efficacy on the relationship between PWB and depressive symptoms. RESULTS: Nearly 8% of the female migrant workers reported experiencing depressive symptoms. The final mediation model showed that the effect of overall psychological wellbeing on depressive symptoms was partially mediated by sexual self-efficacy. Specifically, 4.1% of the effect of overall PWB on depressive symptoms was mediated through sexual self-efficacy. In the PWB subdimension analyses, sexual self-efficacy mediated 14.3% of the effect of personal growth, 8.8% of the effect of purpose in life, 8.0% of the effect of autonomy, and 7.8% of the effect of environmental mastery on depressive symptoms, respectively. CONCLUSION: The study findings demonstrate that sexual self-efficacy plays an important role in the relationship between psychosocial wellbeing and depressive symptoms among female migrant workers in industrial zones in Vietnam. Improving psychosocial wellbeing and promoting sexual health including sexual self-efficacy should be prioritized when addressing depressive symptoms and mental health concerns among industrial zone female migrant workers in Vietnam, which may also be applicable in other low- and middle-income countries with similar socio-cultural settings.

Background: The provider-patient relationship has been implicated as a positive force in health outcomes. This study examined the provider-patient relationship in the setting of integrated, partially-integrated, and non-integrated opioid use disorder (OUD) and HIV care models in Vietnam. Objective: To examine the provider-patient relationship in the setting of integrated, partially integrated, and non-integrated OUD and HIV treatment in North Vietnam. Methods: Between 2013 and 2018, we conducted face-to-face qualitative interviews with 44 patients living with HIV and OUD and 43 providers in northern Vietnam. These were analyzed using a semantic, inductive approach to qualitative thematic analysis. Results: Several themes were identified. 1) Trust was important to the patient-provider relationship and sensitive to provider attitudes and competence. 2) Patients perceived greater provider competence and understanding of patient health problems in integrated treatment. 3) Patient-provider relationships were initially superficial but deepened over time, facilitated by continuity of care. Conclusions: Patient perceptions of competence and respect were important to feeling cared for. Providers felt empathy and competence came with more experience caring for patients with OUD and HIV.
RESUMEN
INTRODUCTION: Methamphetamine use threatens positive treatment outcomes in substance use and HIV, for people with opioid use disorders (POUD) in many countries. This paper describes the adaptation of four evidence-based interventions (EBI) (motivational interviewing, contingency management, Matrix group model and SMS text messaging) for treating methamphetamine use among POUD receiving methadone maintenance therapy in Vietnam. METHODS: Following the ADAPT-ITT (Assessment-Decision-Administration-Production-Topical experts-Training-Testing) framework, we conducted 16 focus group discussions with POUD (n = 25) and providers (n = 22) at four methadone clinics in two largest cities (Hanoi in the North, Ho Chi Minh City in the South) to assess patterns of methamphetamine use and to get feedback on proposed EBIs. The proposed EBIs were properly adapted and used to train providers in two of the four methadone clinics. The revised EBIs were tested over 12 weeks among 42 POUD on methadone who use methamphetamine. Post-intervention feedback served to fine-tune the revised EBIs. RESULTS: Insights about patterns of methamphetamine use suggested that EBIs should focus on different triggers to methamphetamine use among POUD receiving methadone treatment in the two cities. All EBIs should emphasise family-related topics to build a strong motivation for treatment. Participants suggested when, where and how each EBI should be delivered. Most participants were satisfied with the adapted EBIs. Limited human resources at methadone clinics might hinder implementation of the adapted EBIs. DISCUSSION AND CONCLUSIONS: We successfully completed the adaptation of EBIs for POUD who use methamphetamine on methadone in Vietnam. The pilot testing of the adapted EBIs demonstrated feasibility and acceptability. TRIAL REGISTRATION: NCT04706624. Registered 13 January 2021. https://clinicaltrials.gov/ct2/show/NCT04706624.

BACKGROUND: Buprenorphine is widely used in the treatment of opioid use disorder (OUD). There are few pharmacokinetic models of buprenorphine across diverse populations. Population pharmacokinetics (POPPK) allows for covariates to be included in pharmacokinetic studies, thereby opening the potential to evaluate the effect of comorbidities, medications, and other factors on buprenorphine pharmacokinetics. This pilot study used POPPK to explore buprenorphine pharmacokinetics in patients with and without HIV receiving buprenorphine for OUD. METHODS: Plasma buprenorphine levels were measured in 54 patients receiving buprenorphine for OUD just prior to and 2-5 h following regular buprenorphine dosing. A linear one-compartment POPPK model with first-order estimation was used to evaluate buprenorphine clearance (CL/F) and volume of distribution (V/F). Covariates included weight and HIV status. RESULTS: All HIV+ patients reported complete past-month adherence to taking antiretroviral therapy that included either efavirenz or nevirapine. Buprenorphine CL/F was 76% higher in HIV+ patients (n = 17) than HIV- patients (n = 37). Buprenorphine V/F was 41% higher in the HIV+ patients. CONCLUSIONS: POPPK can be used to model buprenorphine pharmacokinetics in a real-world clinical population. While interactions between ART and buprenorphine alter buprenorphine CL/F, we also found alteration in V/F. Proportionate changes in CL/F and V/F might indicate a primary effect on bioavailability (F) rather than two separate effects. These findings indicate reduced buprenorphine bioavailability in patients with HIV.

OBJECTIVES: To assess the severity of methamphetamine use among methadone maintenance treatment (MMT) patients in Vietnam with opioid use disorder and concurrent methamphetamine use, and to identify risk factors associated with higher severity of methamphetamine use. METHODS: We used survey data and medical record abstractions from 428 people with opioid use disorder who also use methamphetamine while partaking in methadone treatment in five clinics in Hanoi, Vietnam. We used multinomial logistic regression to assess other risk factors and problems associated with high methamphetamine use severity. RESULTS: Those who reported injecting heroin in the past 3 months (AOR = 4.05, 95% CI [1.30, 12.55], p = 0.02), having a longer history of lifetime heroin use (AOR = 1.13, 95% CI [1.03, 1.24], p < 0.01), and having higher cravings (AOR = 1.97, 95% CI [1.31, 2.98], p < 0.01) and fatigue (AOR = 1.25, 95% CI [0.96, 1.61], p = 0.09) related to methamphetamine withdrawal had greater odds of high methamphetamine use severity. One of five clinics had a significantly higher percentage of methamphetamine use severity than others. CONCLUSION: Successful MMT in patients with opioid use disorder in Vietnam may additionally require methamphetamine-focused screening and intervention.

In this study, we measured the concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) in the blood of 9-year-old children living in a dioxin hotspot area and a nonexposed area in Vietnam. Forty-five blood samples were collected in the hotspot area while twelve pooled blood samples were collected in the nonexposed area. We found that the dioxin level of children in the hotspot was significantly higher than that of children in the nonexposed area. The total TEQ of PCDD/Fs in the hotspot and the nonexposed was 10.7 and 3.3 pg TEQ/g fat, respectively. However, TCDD, the maker of Agent Orange, was not detected in the blood of children in the hotspot area. In the hotspot area, four congeners 1,2,3,4,6,7,8-HpCDD, 1,2,3,4,7,8-HxCDF, 1,2,3,6,7,8-HxCDF, and 1,2,3,4,6,7,8-HpCDF in mothers' breast milk showed a significantly positive correlation with those in children's serum although the correlations of 1,2,3,7,8-PeCDD and 2,3,4,7,8-PeCDF were not significant. In addition, the duration of breastfeeding also correlates with dioxins in children. These results suggested that children in the hotspot area were exposed to dioxin through mothers' milk and other foods or environmental factors. The present study is the first study that shows dioxin levels in Vietnamese children.
RESUMEN
BACKGROUND: Non-prescribed opioid use is illegal in Vietnam. People who are apprehended for use of non-prescribed opioids may be arrested and incarcerated or sent to compulsory rehabilitation centers. For those on medication to treat opioid use disorder (MOUD), incarceration in either setting may disrupt treatment. This study estimates the effects of incarceration and compulsory rehabilitation on MOUD and HIV treatment outcomes in Vietnam. METHODS: Data are from a clinical trial testing the effects of MOUD on HIV viral suppression in six Vietnamese HIV clinics. Participants were assessed quarterly for 12 months. We assessed the associations between incarceration or compulsory rehabilitation during months 0-9 and study outcomes of receipt of MOUD, HIV clinic engagement, and antiretroviral therapy prescription during months 9-12, among those who were released by month 9 of the study, using logistic regression and zero-inflated negative binomial models. RESULTS: At nine months, 25 of 258 participants (9.7%) were incarcerated or sent to compulsory rehabilitation at least once and completed the month 9 assessment. Of those, 19 (76.0%) did not receive MOUD in months 9 through 12. Both incarceration and compulsory rehabilitation were negatively associated with subsequent receipt of MOUD (aOR = 0.05, 95% CI = (0.01, 0.24); 0.14 (0.04, 0.50), respectively) and HIV clinic engagement (aOR = 0.13, 95% CI = (0.03, 0.71); 0.09 (0.02, 0.39), respectively). In the final three months of the study, participants who were incarcerated had 42.5 fewer days of MOUD (95% CI = 23.1, 61.9), and participants in compulsory rehabilitation had 46.1 fewer days of MOUD (95% CI = 33.8, 58.4) than those not incarcerated or in compulsory rehabilitation. CONCLUSION: Our findings suggest that both incarceration and compulsory rehabilitation disrupt MOUD and HIV treatment among people with HIV and Opioid Use Disorder in Vietnam. Prioritization of evidence-based strategies to support engagement in care for people who use drugs could potentially expand HIV and Opioid Use Disorder treatment access and curb substance use more effectively than reliance on incarceration or compulsory rehabilitation.
