: Globally, there are concerns about access to healthcare and harm reduction services for people who use drugs (PWUD) during the coronavirus disease 2019 (COVID-19) pandemic. Members from the Network of Early Career Professionals working in Addiction Medicine shared their experiences of providing treatment to PWUD during the COVID-19 pandemic. Drawing on these qualitative reports, we highlight the similarities and discrepancies in access to services for PWUD in 16 countries under COVID-10 restrictions. In most countries reported here, efforts have been made to ensure continued access to services, such as mobilising opioid agonist maintenance treatment and other essential medicines to patients. However, due to travel restrictions and limited telemedicine services, several Network of Early Career Professionals working in Addiction Medicine members from lower-resourced countries experienced challenges with providing care to their patients during periods of COVID-19 lock-down. The insights provided in this commentary illustrate how the COVID-19 lock-down restrictions have impacted access to services for PWUD.

INTRODUCTION: Methadone is accepted as an alternative therapy in opioid use disorders worldwide. Methadone responsiveness, however, is affected by a range of CYP450 enzymes and OPRM1 polymorphisms.
OBJECTIVE: This study sought to detect CYP2B6 and OPRM1 variants and their genotypes, as major contributors to inter-variability in methadone responsiveness and methadone dose requirements.
METHODS: We carried out a prospective experimental one-phase pharmacogenetic study in four addiction clinics in Malaysia. Patients on stable methadone maintenance therapy were recruited. The prevalence of the CYP2B6 and OPRM1 polymorphisms was determined using a nested polymerase chain reaction (PCR), followed by genotyping. A two-step multiplex PCR method was developed to simultaneously detect the 26 SNPs in these two genes.
RESULTS: 120 males were recruited for this study. The patients were between 21and 59 years old, although the majority of the patients were in their 30s. C64T and G15631T in CYP2B6and G31A, G691C, and A118G in OPRM1 were found to be polymorphic, and the allelic frequencies of each were calculated. We further detected eight new haplotypes.
CONCLUSION: C64T and G15631T in CYP2B6and G31A, G691C, and A118G in OPRM1were found to be polymorphic. The new haplotypes may give a new insight on methadone clinics.

Adherence to Antiretroviral Therapy Among Incarcerated Persons with HIV: Associations with Methadone and Perceived Safety

With adequate support, people with HIV (PWH) may achieve high levels of adherence to antiretroviral therapy (ART) during incarceration. We examined factors associated with ART utilization and adherence among incarcerated PWH (N = 150) in Indonesia. ART utilization was positively associated with HIV status disclosure (adjusted odds ratio [aOR] = 5.5, 95% CI 1.2-24.1, p = 0.023), drug dependency (aOR = 3.9, 95% CI 1.2-12.6, p = 0.022), health service satisfaction (aOR = 3.2, 95% CI 1.7-6.2, p treatment (aOR = 1.6, 95% CI 1.1-2.5, p = 0.011), and negatively associated with chance locus of control (aOR = 0.3, 95% CI 0.1-0.7, p = 0.013). Most participants utilizing ART (74.5%) reported less than "perfect" ART adherence. ART adherence was independently associated with perceived personal safety (β = 0.21, 95% CI 0.01-0.40, p = 0.032) and methadone utilization (β = 0.84, 95% CI 0.10-1.67, p = 0.047). PWH receiving methadone had a sixfold higher adjusted odds of being highly-adherent to ART (aOR = 6.3, 95% CI 1.1-35.7, p = 0.036). Interventions that increase methadone utilization and personal safety may improve ART adherence among incarcerated PWH.

Fulltext Retention in clinical trials after prison release: results from a clinical trial with incarcerated men with HIV and opioid dependence in Malaysia

Background: Study retention is a major challenge in HIV clinical trials conducted with persons recruited from correctional facilities. Objective: To examine study retention in a trial of within-prison methadone initiation and a behavioral intervention among incarcerated men with HIV and opioid dependence in Malaysia. Methods: In this 2x2 factorial trial, 296 incarcerated men with HIV and opioid dependence were allocated to (1) an HIV risk reduction intervention, the Holistic Health Recovery Program for Malaysia (HHRP-M), (2) pre-release methadone initiation, (3) both interventions, or (4) standard care (NCT02396979). Here we estimate effects of these interventions on linkage to the study after prison release and completion of post-release study visits. Results: Most participants (68.9%) completed at least one post-release study visit but few (18.6%) completed all 12. HHRP-M was associated with a 13.5% (95% confidence interval (CI): 3.8%, 23.2%) increased probability of completing at least one post-release study visit. Although not associated with initial linkage, methadone treatment was associated with an 11% (95% CI: 2.0%, 20.6%) increased probability of completing all twelve post-release study visits. Being subject to forced relocation outside Kuala Lumpur after prison release decreased retention by 43.3% (95% CI: -51.9%, -34.8%). Conclusion: Retaining study participants in HIV clinical trials following prison release is challenging and potentially related to the broader challenges that participants experience during community reentry. Researchers conducting clinical trials with this population may want to consider methadone and HHRP as means to improve post-release retention, even in clinical trials where these interventions are not being directly evaluated.
