Facing the future of substance use disorders treatment in Vietnam - A case study for international development and cooperation.

Vietnam made progress transitioning from a criminal justice to a health treatment response for substance use disorders (SUD) in recent years. This case study describes the evolution of Vietnam's SUD treatment system from 2005 to 2020 to understand and learn from the phases of its development. The case study is based on data from a predesigned interview guide for 47 respondents, literature and policy desk review and direct experience of the authors. Vietnam saw remarkable growth of opioid use disorder (OUD) treatment from 2005 when methadone was unavailable, to 2020 with 335 methadone clinics in all 63 provinces serving more than 52,200 patients. The growth in OUD treatment accounts for much of Vietnam's success managing its HIV epidemic for which injection drug use was a major vector. An unintended consequence, however, focused only on OUD as a strategy to address HIV and was unable to address multiple substances. Most elements of a modern evidence and community-based SUD treatment system exist in Vietnam; however, they are siloed and influenced by multiple government administrative jurisdictions. Faced with rising amphetamine and persistent alcohol use, the path ahead for Vietnam involves a choice between a reliance on compulsory rehabilitation centers or a plan to broaden the scope of substances and treatments, and further integrate with Vietnam's commune-based primary health system.

IVIg for Treatment of Severe Refractory Heparin-Induced Thrombocytopenia.

BACKGROUND: Heparin-induced thrombocytopenia (HIT) complicated by severe thrombocytopenia and thrombosis can pose significant treatment challenges. Use of alternative anticoagulants in this setting may increase bleeding risks, especially in patients who have a protracted disease course. Additional therapies are lacking in this severely affected patient population. METHODS: We describe three patients with HIT who had severe thromboembolism and prolonged thrombocytopenia refractory to standard treatment but who achieved an immediate and sustained response to IVIg therapy. The mechanism of action of IVIg was evaluated in these patients and in five additional patients with severe HIT. The impact of a common polymorphism (H/R 131) in the platelet IgG receptor FcγRIIa on IVIg-mediated inhibition of platelet activation was also examined. RESULTS: At levels attained in vivo, IVIg inhibits HIT antibody-mediated platelet activation. The constant domain of IgG (Fc) but not the antigen-binding portion (Fab) is required for this effect. Consistent with this finding, IVIg had no effect on HIT antibody binding in a solid-phase HIT immunoassay (platelet factor 4 enzyme-linked immunoassay). The H/R131 polymorphism in FcγRIIa influences the susceptibility of platelets to IVIg treatment, with the HH131 genotype being most susceptible to IVIg-mediated inhibition of antibody-induced activation. However, at high doses of IVIg, activation of platelets of all FcγRIIa genotypes was significantly inhibited. All three patients did well on long-term anticoagulation therapy with direct oral anticoagulants. CONCLUSIONS: These studies suggest that IVIg treatment should be considered in patients with HIT who have severe disease that is refractory to standard therapies.

Methadone maintenance therapy in Vietnam: an overview and scaling-up plan.

Vietnam is among the countries with the highest rate of HIV transmission through injecting drug users. HIV prevalence among injecting drug users is 20% and up to 50% in many provinces. An estimated number of drug users in the country by the end of 2011 were 171,000 in which the most common is heroin (85%). Detoxification at home, community, and in rehabilitation centers have been the main modalities for managing heroin addiction until Methadone Maintenance Treatment (MMT) was piloted in 2008. Recent reports have demonstrated positive treatment outcomes. Incidence of HIV was found remarkably low among patients on MMT. Treatment has significantly improved the quality of life as well as stability for society. The government has granted the Ministry of Health (MoH) to expand Methadone treatment to at least 30 provinces to provide treatment for more than 80,000 drug users by 2015. The Vietnam Administration for HIV/AIDS Control (VAAC) and MOH have outlined the role and responsibility of key departments at the central and local levels in implementing and maintaining MMT treatment. This paper will describe the achievements of the MMT pilot program and the scaling-up plan as well as strategies to ensure quality and sustainability and to overcome the challenges in the coming years.

HIV risk among drug-using men who have sex with men, men selling sex, and transgender individuals in Vietnam.

Knowledge about drug use and its association with HIV risk among men who have sex with men is limited. Although the HIV epidemic among this population in Vietnam is increasingly acknowledged, understanding the impact of drug use on the spread of HIV is largely lacking. Using qualitative data from in-depth interviews and focus group discussions with 93 drug users, 15 non-drug users and 9 community stakeholders, this analysis explores emerging patterns of drug use and risk factors for engaging in risk behaviours among drug-using men having sex with men, men selling sex and transgender individuals in Hanoi and Ho Chi Minh City. Findings revealed that drug use is shifting from heroin to ecstasy and ice. Drug users reported unsafe sex associated with drug use and men selling sex were particularly at elevated risk because of using drugs as a tool for sex work and trading sex for drugs. These findings are guiding development of programmes addressing unmet HIV-prevention needs in Vietnam.

A national study of the substance abuse treatment workforce.

This study's purpose is to gain a current perspective on the substance abuse treatment field's workforce. The data are from the Retrospective Study of treatment professionals designed to document how the Treatment Improvement Protocols published by the Center for Substance Abuse Treatment have influenced the implementation of best practices. The Retrospective Study consisted of a two-wave cross-sectional survey with telephone follow-up. Data for this study were from demographic information on Wave 1 study participants, which had a response rate of 80.1% (N = 3,267). The results of the study showed that most treatment professionals are White (84.5%) and middle-aged (i.e., between 40 and 55 years old) and slightly more are female (50.5.0%) than male (49.5%). Treatment professionals tend to enter the field and stay in it, and almost 80.0% of respondents possess a bachelor's degree or higher. In addition, most treatment professionals are licensed or certified and treat clients from different racial and ethnic backgrounds than themselves. Implications for the provision of treatment services are discussed.
