    Background: Erectile dysfunction (ED) is commonly associated with methadone usage. However, little data is known regarding the health-seeking behavior for ED in the methadone maintenance treatment (MMT) population. This study aimed to determine the health-seeking behavior of MMT patients with ED who perceived themselves as having ED. We aimed to assess the attitudes and health-seeking behavior, the effectiveness of the treatment and the factors associated with treatment-seeking behavior. Methods: This was an observational questionnaire-based study. Patients were first screened for ED (n = 154) using the International Index of Erectile Function-5 (IIEF-5). Fifty patients with ED were evaluated for health-seeking behavior for ED. Results: More than half of the patients who thought they had ED (78%) believed their sex life was affected. Most patients (48%) did not seek any information regarding ED. Education level (p = 0.017) and marital status (p = 0.008) were predictive factors of health-seeking behavior. Conclusions: The health-seeking rate among MMT patients with ED needs to be improved. Measures to increase awareness of ED in MMT patients should be taken to overcome the barrier to health-seeking behavior. Health practitioners should take action to screen ED in this population to increase the detection rate and offer appropriate management according to the patients' needs.

    Drugs with complex pharmacology are used in the management of drug use disorder (DUD) and HIV/AIDS in Malaysia and in parts of South-East Asia. Their multiethnic populations suggest complexity due to the genetic polymorphism, such as CYP2B6 that metabolizes methadone and anti-retroviral.

    INTRODUCTION: Methadone maintenance therapy (MMT) is crucial for HIV prevention and treatment in people who inject opioids. In Malaysia, a large proportion of the prison population is affected by both HIV and opioid use disorders. This study assessed individual preferences and factors associated with interest in receiving MMT among male prisoners meeting criteria for opioid dependence in Malaysia.

    METHODS: A convenience sample of 96 HIV-positive and 104 HIV-negative incarcerated men who met pre-incarceration criteria for opioid dependence was interviewed using a structured questionnaire to examine participant characteristics and attitudes toward MMT. Factors associated with interest in prison-based MMT initiation were identified using logistic regression analysis.

    RESULTS: Among all participants, 85 (42.5%) were interested in receiving MMT within prison. Independent correlates of interest in prison-based MMT were being previously married (AOR=4.15, 95% CI: 1.15, 15.02), previously incarcerated (AOR=5.68, 95% CI: 1.54, 21.02), depression (AOR=3.66, 95% CI: 1.68, 7.98), daily heroin use in the 30days prior to incarceration (AOR=5.53, 95% CI: 1.65, 18.58), and more favorable attitudes toward MMT (AOR=19.82, 95% CI: 6.07, 64.74).

    CONCLUSIONS: Overall, interest in receiving prison-based MMT was low, and was associated with adverse social, mental health, and drug use consequences. Incarceration provides a unique opportunity to initiate MMT for those who need it, however, optimal scale-up efforts must be systemic and address modifiable factors like improving attitudes toward and motivation for MMT. Informed or shared decision-making tools may be useful in improving expectations and acceptability of MMT.

    BACKGROUND: Opioid substitution with methadone maintenance treatment (MMT) is shown to reduce illicit opioid use and renew social functioning. Understanding factors that undermine clients' social functioning during MMT treatment is vital for improving treatment compliance and quality of life.

    METHOD: A total of 210 respondents who were already enrolled in a formal MMT program in Myanmar were recruited from five cities through stratified random sampling for this cross-sectional study. The addiction severity index (ASI) was used to objectively assess respondents social functioning in the last 30 days. Higher ASI scores denote poorer social functioning.

    RESULT: Respondents total ASI scores in the respective domains were: employment (47.4%), alcohol (44.4%), drug use (7.2%), legal (49.2%) and social-family relationship (10.7%). Those reported to have never injected drugs in the last 30 days had lower ASI total scores than those who reported injection drug use (p = 0.01). After identifying the differences in ASI total scores, we found there were significant associations in the clients' hepatitis C status, age category, frequency of heroin injection, quality of life score, marital status, current leisure status with family/friend, current history of injection in the last 30 days, income status, satisfaction with current marital status, as well as reported drug and alcohol use (p Treatment providers must take heed of these apparent impediment to ensure clients chequered social functioning does not undermine their treatment compliance.

    Background: Long-term opioid therapy is a risk factor for low bone mineral density (BMD). However, other factors may also contribute to low BMD. Several studies have examined the variables that might contribute to low BMD in patients receiving opioid replacement therapy (OST). However, to our knowledge, there was no systemic review conducted to address this particular issue. Thus, we reviewed the articles on the factors associated with low BMD in the population of opioid use disorder receiving substitution therapy. Methods: The articles that examined correlates or risk factors of low BMD in OST population were retrieved from OVID, SCOPUS, and PUBMED from inception until July 2020 by two independent investigators. Results: A total of 429 articles from three databases were retrieved initially. After screening based on eligibility criteria, five articles were included in the final analysis. The risk factors or correlates found to be significantly associated with low BMD in the OST population include male gender, low body mass index, low testosterone level, methadone or heroin use, and longer duration of heavy alcohol use. The review limitations include small sample sizes and inconsistent definition of variables. Conclusion: OST patients should be screened for BMD and its associated factors. Guidelines and training of practitioners involving in the OST service should be provided to increase the detection of low BMD in the OST population.

    BACKGROUND: Approximately 40%-90% of people who inject drugs (PWID) in Malaysia have hepatitis C (HCV). PWID continue to be disproportionately affected by HCV due to their lack of knowledge, perceived risk and interest in HCV treatment. Education interventions may be an effective strategy for increasing HCV knowledge in PWID, and harm reduction services are uniquely positioned to implement and deploy such interventions.

    METHODS: We recruited 176 clients from methadone maintenance treatment (MMT: N=110) and needle/syringe programs (NSP: N=66) between November 2015 and August 2016. After baseline knowledge assessments, clients participated in a standardized, 45-min HCV education program and completed post-intervention knowledge assessments to measure change in knowledge and treatment interest.

    RESULTS: Participants were mostly male (96.3%), Malay (94.9%), and in their early 40s (mean=42.6years). Following the intervention, overall knowledge scores and treatment interest in MMT clients increased by 68% and 16%, respectively (p<0.001). In contrast, NSP clients showed no significant improvement in overall knowledge or treatment interest, and perceived greater treatment barriers. Multivariate linear regression to assess correlates of HCV knowledge post-intervention revealed that optimal dosage of MMT and having had an HIV test in the past year significantly increased HCV knowledge. Having received a hepatitis B vaccine, however, was not associated with increased HCV knowledge after participating in an education session.

    CONCLUSION: Generally, HCV knowledge and screening is low among clients engaged in MMT and NSP services in Malaysia. Integrating a brief, but comprehensive HCV education session within harm reduction services may be a low-cost and effective strategy in improving overall HCV knowledge and risk behaviors in resource-limited settings. In order to be an effective public health approach, however, education interventions must be paired with strategies that improve social, economic and political outcomes for PWID. Doing so may reduce HCV disparities by increasing screening and treatment interest.

    BACKGROUND: Opioid misuse and dependence is a global issue with a huge negative impact. In Malaysia, heroin is still the main illicit drug used, and methadone maintenance treatment (MMT) has been used since 2005.
    OBJECTIVE: To evaluate the effectiveness of MMT.
    METHODS: This was a cross-sectional study conducted in 103 treatment centers between October and December 2014 using a set of standard questionnaires. Data were analyzed using SPSS Statistics 20.
    RESULTS: There were 3254 respondents (93.6% response rate); of these 17.5% (n = 570) transferred to another treatment center, 8.6% (n = 280) died, 29.2% (n = 950) defaulted, and 7.6% (n = 247) were terminated for various reasons. Hence, 1233 (37%) respondents' baseline and follow-up data were further analyzed. Respondents had a mean age of 39.2 years old and were mainly male, Malay, Muslim, married (51.1%, n = 617), and currently employed. Few showed viral seroconversion after they started MMT (HIV: 0.5%, n = 6; Hepatitis B: 0.3%, n = 4; Hepatitis C: 2.7%, n = 29). There were significant reductions in opioid use, HIV risk-taking score (p < 0.01), social functioning (p < 0.01), crime (p < 0.01), and health (p < 0.01). However, there were significant improvements in quality of life in the physical, psychological, social, and environmental domains. Factors associated with change were being married, employed, consuming alcohol, and high criminality at baseline. Lower methadone dosage was significantly associated with improvements in the physical, psychological, and environmental domains.
    Conclusion/Importance: The MMT program was found to be successful; hence, it should be expanded.

    Objective: This case report highlights the risk of Torsade de Pointes (TdP), a life threatening cardiac arrhythmia in a heroin dependent patient receiving methadone substitution therapy who was prescribed erythromycin for upper respiratory tract infection. Method: We report a case of a 35-year-old Malay man on methadone maintenance treatment who developed TdP possibly due to drug interaction between methadone and erythromycin. Results: The
    patient reported feeling unwell, chest pain and feeling dizzy after consuming 2 doses of erythromycin. ECG monitoring showed prolonged rate-corrected QT interval leading to TdP. The patient was admitted to the ward where the cardiac arrhythmia ceased following methadone discontinuation. This cardiac arrhythmia was most likely due to drug interaction between methadone and erythromycin (an enzyme inhibitor) which led to an increase in methadone concentration and potentiated the adverse effects. Conclusion: As methadone is a beneficial treatment for heroin dependent patients, the risk of cardiac arrhythmia is of great concern. To avoid complications of drug interaction, patients on methadone therapy should be advised to seek medical assessment before taking other drugs. As TdP is life threatening, it is thus important that physicians and psychiatrists involved in the treatment of
    heroin dependent patients on methadone substitution therapy be made aware of this risk.

    Methadone maintenance therapy has been found to be an effective harm reduction treatment for opioid use disorder. However evidence of its benefits over a longer duration of treatment is limited as most studies focus on its short term benefits. As methadone maintenance therapy reaches a decade since its implementation in Malaysia, this study sought to examine the effectiveness of methadone treatment, change in quality of life among patients since entry to methadone treatment, as well as factors predicting the magnitude of change in quality of life. This study found that methadone maintenance therapy was effective in reducing heroin use, injecting practices and crime, and in improving in social functioning and physical symptoms, but not in reducing sex-related HIV risk-taking behavior. Though patients had a significantly better quality of life at follow-up than at entry to methadone maintenance therapy, the improvement in quality of life was not significantly greater as the duration of treatment increased. Age above 50 years old, human immunodeficiency virus (HIV) positive status and physical symptoms predicted a poorer improvement in quality of life between baseline and follow-up. On the other hand, patients with hepatitis B showed a greater improvement in quality of life in the social relationships domain compared to patients without hepatitis B. In conclusion, methadone maintenance therapy is an effective treatment for opioid use disorder and improves quality of life but its benefits in further improving quality of life beyond a decade of treatment need further evaluation.

    Introduction: Methadone Maintenance Treatment (MMT) is the commonly used intervention for opioid dependents among Malays in FELDA settlements. However, relapse is common. Since majority of Malays are Muslims, Islamic Rehabilitation Intervention Module (ISRIM) using Health Belief Model (HBM) can be implemented as an intervention for reduction of relapse among opioid dependents in FELDA community. The objective of this study were to develop, implement and evaluate the effectiveness of ISRIM in the reduction of relapse among opioids dependent Malay males in FELDA communities in Jengka, Pahang. Methods: A single blind, cluster randomized controlled trial utilizing simple randomization was conducted, involving 10 MMT clinics. Intervention group received ISRIM for one session per week for four consecutive weeks, while control group were put on wait-list. Outcome was relapse, measured monthly for 6 months follow-up by the positive urine for drugs rapid test. Generalized Estimating Equations (GEE) was used as the main effectiveness analysis. Intention-to-treat (ITT), per protocol (PP) analysis, interaction terms, construct terms and key assumption terms were utilized. Results: Individual participation rate was 88.3%. All group comparisons at baseline were not significant (p>0.05). Cumulative relapse after 6-months follow-up for intervention and control group was 13.8% and 31.2%. There was significant difference in relapse between baseline, post-inter-vention and 6-months follow-up within intervention and control group (Q=29.06 vs 61.39,p

    BACKGROUND: As HIV incidence and mortality continue to increase in eastern Europe and central Asia, particularly among people who inject drugs (PWID), it is crucial to effectively scale-up opioid agonist therapy (OAT), such as methadone or buprenorphine maintenance therapy, to optimise HIV outcomes. With low OAT coverage among PWID, we did an optimisation assessment using current OAT procurement and allocation, then modelled the effect of increased OAT scale-up on HIV incidence and mortality for 23 administrative regions of Ukraine.

    METHODS: We developed a linear optimisation model to estimate efficiency gains that could be achieved based on current procurement of OAT. We also developed a dynamic, compartmental population model of HIV transmission that included both injection and sexual risk to estimate the effect of OAT scale-up on HIV infections and mortality over a 10-year horizon. The compartmental population model was calibrated to HIV prevalence and incidence among PWID for 23 administrative regions of Ukraine. Sources for regional data included the SyrEx database, the Integrated Biological and Behavioral Survey, the Ukrainian Center for Socially Dangerous Disease Control of the Ministry of Health of Ukraine, the Public Health Center of the Ministry of Health of Ukraine, and the Ukrainian Census.

    FINDINGS: Under a status-quo scenario (OAT coverage of 2·7% among PWID), the number of new HIV infections among PWID in Ukraine over the next 10 years was projected to increase to 58 820 (95% CI 47 968-65 535), with striking regional differences. With optimum allocation of OAT without additional increases in procurement, OAT coverage could increase from 2·7% to 3·3% by increasing OAT doses to ensure higher retention levels. OAT scale-up to 10% and 20% over 10 years would, respectively, prevent 4368 (95% CI 3134-5243) and 10 864 (7787-13 038) new HIV infections and reduce deaths by 7096 (95% CI 5078-9160) and 17 863 (12 828-23 062), relative to the status quo. OAT expansion to 20% in five regions of Ukraine with the highest HIV burden would account for 56% of new HIV infections and 49% of deaths prevented over 10 years.

    INTERPRETATION: To optimise HIV prevention and treatment goals in Ukraine, OAT must be substantially scaled up in all regions. Increased medication procurement is needed, combined with optimisation of OAT dosing. Restricting OAT scale-up to some regions of Ukraine could benefit many PWID, but the regions most affected are not necessarily those with the highest HIV burden.

    OBJECTIVES: We sought to examine the association between dispensation of methadone maintenance therapy (MMT) and antiretroviral therapy (ART) at the same facility, across multiple low-barrier dispensing outlets, and achieving optimal adherence to ART among people who use illicit drugs (PWUD).

    METHODS: We used data from the AIDS Care Cohort to Evaluate Exposure to Survival Services (ACCESS) study, a long-running study of a community-recruited cohort of HIV-positive PWUD, linked to comprehensive HIV clinical records in Vancouver, Canada, a setting of no-cost, universal access to HIV care. The longitudinal relationship between MMT-ART dispensation at the same facility and the odds of ≥ 95% ART adherence was analysed using multivariable generalized linear mixed-effects modelling. We conducted a further analysis using a marginal structural mode with inverse probability of treatment weights as a sensitivity analysis.

    RESULTS: This study included data on 1690 interviews of 345 ART- and MMT-exposed participants carried out between June 2012 and December 2017. In the final multivariable model, MMT-ART dispensation, compared with nondispensation at the same facility, was associated with greater odds of achieving ≥ 95% adherence [adjusted odds ratio (AOR) 1.56; 95% confidence interval (CI) 1.26-1.96]. A marginal structural model estimated a 1.48 (95% CI 1.15-1.80) greater odds of ≥ 95% adherence among participants who reported MMT-ART dispensation at the same facility compared with those who did not.

    CONCLUSIONS: The odds of achieving optimal adherence to ART were 56% higher during periods in which MMT and ART medications were dispensed at the same facility, in a low-barrier setting. Our findings highlight the need to consider a simpler integrated approach with medication dispensation at the same facility in low-threshold settings.

    A young male presented with many years of delusions and hallucinations, with concurrent heroin use and subsequent amphetamine uses. There were no depressive or manic symptoms and psychotic symptoms prior to the amphetamine use. After the trials of two atypical antipsychotics and later clozapine due to treatment resistance, adherence and functionality were poor and there was still persistent drug use. As a result, a long acting injectable adjunct was commenced, but only minimal effects were observed. However after initiation of directly observed treatment of clozapine with methadone, there has been functional and clinical response and drug use has ceased.

    Incarcerated people living with HIV and opioid dependence face enormous challenges to accessing evidence-based treatment during incarceration and after release into the community, placing them at risk of poor HIV treatment outcomes, relapse to opioid use and accompanying HIV transmission risk behaviors. Here we describe in detail the design and implementation of Project Harapan, a prospective clinical trial conducted among people living with HIV and opioid dependence who transitioned from prison to the community in Malaysia from 2010 to 2014. This trial involved 2 interventions: within-prison initiation of methadone maintenance therapy and an evidence-based behavioral intervention adapted to the Malaysian context (the Holistic Health Recovery Program for Malaysia, HHRP-M). Individuals were recruited and received the interventions while incarcerated and were followed for 12months after release to assess post-release HIV transmission risk behaviors and a range of other health-related outcomes. Project Harapan was designed as a fully randomized 2×2 factorial trial where individuals would be allocated in equal proportions to methadone maintenance therapy and HHRP-M, methadone maintenance therapy alone, HHRP-M alone, or control. Partway through study implementation, allocation to methadone maintenance therapy was changed from randomization to participant choice; randomization to HHRP-M continued throughout. We describe the justification for this study; the development and implementation of these interventions; changes to the protocol; and screening, enrollment, treatment receipt, and retention of study participants. Logistical, ethical, and analytic issues associated with the implementation of this study are discussed.

    Kratom is a medicinal plant that exhibits promising results as an opiate substitute. However, there is little information regarding the abuse profile of its main psychoactive constituent, mitragynine (MG), particularly in relapse to drug abuse. Using the place conditioning procedure as a model of relapse, this study aims to evaluate the ability of MG to induce conditioned place preference (CPP) reinstatement in rats. To evaluate the cross-reinstatement effects, MG and morphine were injected to rats that previously extinguished a morphine- or MG-induced CPP. Following a CPP acquisition induced by either MG (10 and 30 mg/kg, i.p.) or morphine (10 mg/kg, i.p.), rats were subjected to repeated CPP extinction sessions. A low dose priming injection of MG or morphine produced a reinstatement of the previously extinguished CPP. In the second experiment of this study, a priming injection of morphine (1, 3 and 10 mg/kg, i.p.) dose-dependently reinstated an MG-induced CPP. Likewise, a priming injection of MG (3, 10 and 30 mg/kg, i.p.) was able to dose-dependently reinstate a morphine-induced CPP. The present study demonstrates a cross-reinstatement effect between MG and morphine, thereby suggesting a similar interaction in their rewarding motivational properties. The findings from this study also suggesting that a priming exposure to kratom and an opioid may cause relapse for a previously abused drug.

    BACKGROUND AND AIMS: Although opioid agonist treatment (OAT) for opioid use disorder (OUD) is cost-effective in settings where the HIV epidemic is concentrated among people who inject drugs, OAT coverage in Ukraine remains far below internationally recommended targets. Scale-up is limited by both OAT availability and demand. This study aimed to evaluate the cost-effectiveness of a range of plausible OAT scale-up strategies in Ukraine incorporating the potential impact of treatment spillover and the real-world demand for addiction treatment.

    DESIGN, SETTING AND PARTICIPANTS: Ten-year horizon (2016-25) modeling study of opioid addiction epidemic and treatment that accommodated potential peer effects in opioid use initiation and supply-induced treatment demand in three Ukrainian cities: Kyiv, Mykolaiv and Lviv, comprising a simulated population of people at risk of and with OUD.

    MEASUREMENTS: Incremental cost per quality-adjusted life-year gained in the simulated population.

    FINDINGS: An estimated 12.2-, 2.4- and 13.4-fold OAT capacity increase over 2016 baseline capacity in Kyiv, Mykolaiv and Lviv, respectively, would be cost-effective at a willingness-to-pay of one per-capita gross domestic product (GDP) per quality-adjusted life-year gained. This result is robust to parametric and structural uncertainty. Even under the most ambitious capacity increase, OAT coverage (i.e. the proportion of people with OUD receiving OAT) over a 10-year modeling horizon would be 20, 11 and 17% in Kyiv, Mykolaiv and Lviv, respectively, owing to limited demand.

    CONCLUSIONS: It is estimated that a substantial increase in opioid agonist treatment (OAT) capacity in three Ukrainian cities would be cost-effective for a wide range of willingness-to-pay thresholds. Even a very ambitious capacity increase, however, is unlikely to reach internationally recommended coverage levels. Further increases in coverage may be limited by demand and would require addressing existing structural barriers to OAT access.

    BACKGROUND: Criminalisation of drug use and compulsory detention has largely characterised the Southeast Asia region's response to people who use drugs. Whilst access to and provision of healthcare for people living in prison are mandated by international human rights standards, many opioid dependent people living in prison continue to lack access to opioid substitution treatment (OST) during incarceration, and face uncertainties of continuity of care beyond the prison gate.

    METHODS: A scoping review using Arksey and O'Malley's framework mapped what is currently known about the continuity of OST post-release in Southeast Asia, with a focus on the three countries (Indonesia, Malaysia, Vietnam) that provide OST in at least one prison. A multi-lingual systematic search (English, Malay, Indonesian, Vietnamese) on Medline, CINAHL, Scopus, Web of Science, PsycINFO and the Cochrane Library collected and reviewed extant relevant published empirical and grey literature including government reports between 2011 and 2021. Of the 365 records found, 18 were eligible for inclusion following removal of duplicates and application of exclusion criteria. These records were charted and thematically analysed.

    RESULTS: Three main themes were generated: Facilitators of post release continuity of care, Barriers to post release continuity of care and Therapeutic considerations supporting post release continuity of care. When individual and structural gaps exist, disruptions to continuity of OST care post release are observed. Adequate methadone dosage of >80mg/day appears significantly associated with retention in post-release OST.

    CONCLUSIONS: The review highlights the facilitators, barriers and therapeutic considerations of continuity of care of OST between prison and community for people living in prisons from Indonesia, Malaysia and Vietnam. Improving community services with family support are key to supporting continued OST adherence post release along with reducing societal stigma towards people who use drugs and those entering or leaving prison. Further efforts are warranted to ensure parity, quality and continuity of OST care post release.

    The study aimed to determine the prevalence of continuity of illicit drug use and its associated factors among Malay opioid users receiving methadone treatment in Kelantan, Malaysia. This cross-sectional study involved a total of 150 respondents. Sociodemographic characteristic of participants, level of religiosity, and quality of life were collected using the self-administered questionnaires. The prevalence of continuity illicit drug use was 38.7% (n = 58) by self-report and 40.7% (n = 61) by positive urine test result for drugs. Positive hepatitis C status and high quality of life in the psychological health domain were associated with low continuity of illicit drug use by self-reported data and urine drug test results. In conclusion, the continuity of illicit drug use among methadone program users is still high, especially among those on methadone therapy for less than 2 years.

    Methadone maintenance treatment is proven to be effective treatment for opioid dependence. Of the many adverse events reported, sexual dysfunction is one of the most common side effects. However, there may be other clinical factors that are associated with sexual dysfunction among methadone users. We conducted a meta-analysis to examine the clinical factors associated with sexual dysfunction among male patients on methadone and buprenorphine treatments, of which eligible studies were selected using prior defined criteria. A total of 2619 participants from 16 eligible studies, published from inception till December 2012, were identified from the PubMed, OVID and EMBASE databases. The included studies provided prevalence estimates for sexual dysfunction among methadone users with a meta-analytical pooled prevalence of 52% (95% confidence interval (CI), 0.39-0.65). Only four studies compared sexual dysfunction between the two groups, with a significantly higher combined odds ratio in the methadone group (odds ratio=4.01, 95% CI, 1.52-10.55, P=0.0049). Our study shows that eight clinical factors are associated with sexual dysfunction among men receiving opioid substitution treatment, namely age, hormone assays, duration of treatment, methadone dose, medical status, psychiatric illness, other current substance use and familial status, and methadone versus buprenorphine treatment. Despite the methodological limitations, the findings of this meta-analysis study may offer better insights to clinicians in dealing with both sexual dysfunction and its related problems.
