RESUMEN

Fentanyl-mixed and substituted heroin is well-documented, but less is known about unintentional fentanyl use among people using stimulants. To determine the prevalence of and racial and ethnic disparities in unintentional fentanyl use among people experiencing a medically attended opioid overdose, we reviewed 448 suspected non-fatal overdose cases attended by a community paramedic overdose response team in San Francisco from June to September 2022. We applied a case definition for opioid overdose to paramedic records and abstracted data on intended substance use prior to overdose. Among events meeting case criteria with data on intended substance use, intentional opioid use was reported by 57.3%, 98.0% of whom intended to use fentanyl. No intentional opioid use was reported by 42.7%, with most intending to use stimulants (72.6%), including methamphetamine and cocaine. No intentional opioid use was reported by 58.5% of Black, 52.4% of Latinx, and 28.8% of White individuals (p = 0.021), and by 57.6% of women and 39.5% of men (p = 0.061). These findings suggest that unintentional fentanyl use among people without opioid tolerance may cause a significant proportion of opioid overdoses in San Francisco. While intentional fentanyl use might be underreported, the magnitude of self-reported unintentional use merits further investigation to confirm this phenomenon, explore mechanisms of use and disparities by race and ethnicity, and deploy targeted overdose prevention interventions.

RESUMEN

BACKGROUND: Incarcerated people with HIV and opioid-dependence often experience poor post-release outcomes in the absence of methadone maintenance treatment (MMT). In a prospective trial, we assessed the impact of methadone dose achieved within prison on linkage to MMT after release. METHODS: From 2010 to 2014, men with HIV (N = 212) and opioid dependence before incarceration were enrolled in MMT within 6 months of release from Malaysia's largest prison and followed for 12-months post-release. As a prospective trial, allocation to MMT was at random and later by preference design (predictive nonetheless). MMT dosing was individually targeted to minimally achieve 80 mg/day. Time-to-event analyses were conducted to model linkage to MMT after release. FINDINGS: Of the 212 participants allocated to MMT, 98 (46 %) were prescribed higher dosages (≥80 mg/day) before release. Linkage to MMT after release occurred in 77 (36 %) participants and significantly higher for those prescribed higher dosages (46% vs 28 %; p = 0.011). Factors associated with higher MMT dosages were being married, on antiretroviral therapy, longer incarceration periods, having higher levels of depression, and methadone preference compared to randomization. After controlling for other variables, being prescribed higher methadone dosage (aHR: 2.53, 95 %CI: 1.42-4.49) was the only independent predictor of linkage to methadone after release. INTERPRETATION: Higher doses of methadone prescribed before release increased the likelihood of linkage to MMT after release. Methadone dosing should be introduced into international guidelines for treatment of opioid use disorder in prisons and further post-release benefits should be explored. FUNDING: National Institute of Drug Abuse (NIDA).

RESUMEN

Background: As the overdose crisis continues in the U.S. and Canada, opioid use disorder (OUD) treatment outcomes for people with co-occurring psychiatric disorders are not well characterized. Our objective was to examine the influence of co-occurring psychiatric disorders on buprenorphine initiation and discontinuation. Methods: This retrospective cohort study used multi-state administrative claims data in the U.S. to evaluate rates of buprenorphine initiation (relative to psychosocial treatment without medication) in a cohort of 236,198 people with OUD entering treatment, both with and without co-occurring psychiatric disorders, grouping by psychiatric disorder subtype (mood, psychotic, and anxiety-and-related disorders). Among people initiating buprenorphine, we assessed the influence of co-occurring psychiatric disorders on buprenorphine retention. We used multivariable Poisson regression to estimate buprenorphine initiation and Cox regression to estimate time to discontinuation, adjusting for all 3 classes of co-occurring disorders simultaneously and adjusting for baseline demographic and clinical characteristics. Results: Buprenorphine initiation occurred in 29.3 % of those with co-occurring anxiety-and-related disorders, compared to 25.9 % and 17.5 % in people with mood and psychotic disorders. Mood (adjusted-risk-ratio[aRR] = 0.82[95 % CI = 0.82-0.83]) and psychotic disorders (aRR = 0.95[0.94-0.96]) were associated with decreased initiation (versus psychosocial treatment), in contrast to greater initiation in the anxiety disorders cohort (aRR = 1.06[1.05-1.06]). We observed an increase in buprenorphine discontinuation associated with mood (adjusted-hazard-ratio[aHR] = 1.20[1.17-1.24]) and anxiety disorders (aHR = 1.12[1.09-1.14]), in contrast to no association between psychotic disorders and buprenorphine discontinuation. Conclusions: We observed underutilization of buprenorphine among people with co-occurring mood and psychotic disorders, as well as high buprenorphine discontinuation across anxiety, mood, and psychotic disorders.

RESUMEN

BACKGROUND: Morbidity and mortality from nonprescribed opioid use and opioid use disorder (OUD) in adolescents have risen dramatically. Medication for opioid use disorder (MOUD) with buprenorphine reduces nonprescribed opioid use and prevents overdoses, though <5% of adolescents with OUD have timely access, partly because of barriers associated with buprenorphine induction. Induction in an inpatient pediatric setting has the potential to address such barriers and improve adolescent MOUD access. METHODS: We developed and implemented a protocol for inpatient buprenorphine induction and linkage to MOUD care within a safety-net health system. After 1 year, we conducted descriptive analysis of participant characteristics, rates of induction completion and treatment linkage, and adverse events. We analyzed field notes from multidisciplinary huddles to identify implementation facilitators and barriers. RESULTS: During May 2021 to July 2022, we completed 46 admissions for 36 patients aged 12 to 21 years. All used fentanyl and no other opioids. Forty of 46 (87%) admissions resulted in completed induction, and 3 additional patients never developed withdrawal symptoms and were discharged with maintenance buprenorphine. Linkage to ongoing treatment occurred within 2 weeks for 31 of 43 (72%) admissions for which buprenorphine was started. We identified facilitators and barriers to program implementation and maintenance. CONCLUSION: These results provide promising preliminary evidence of the feasibility of inpatient buprenorphine induction for adolescents with OUD. Given the public health urgency and severe shortage of adolescent access to MOUD, these results prompt consideration of broader clinical implementation and research to facilitate rapid expansion of access to evidence-based OUD care.

RESUMEN

INTRODUCTION: Mortality is elevated after prison release and may be higher in people with HIV and opioid use disorder (OUD). Maintenance with opioid agonist therapy (OAT) like methadone or buprenorphine reduces mortality in people with OUD and may confer benefits to people with OUD and HIV leaving prison. Survival benefits of OAT, however, have not been evaluated prospectively in people with OUD and HIV leaving prison. METHODS: This study prospectively evaluated mortality after prison release and whether methadone initiated before release increased survival after release in a sample of men with HIV and OUD (n = 291). We linked national death records to data from a controlled trial of prerelease methadone initiation conducted from 2010 to 2014 with men with HIV and OUD imprisoned in Malaysia. Vital statistics were collected through 2015. Allocation to prerelease methadone was by randomization (n = 64) and participant choice (n = 246). Cox proportional hazards models were used to estimate treatment effects of prerelease methadone on postrelease survival. RESULTS: Overall, 62 deaths occurred over 872.5 person-years (PY) of postrelease follow-up, a crude mortality rate of 71.1 deaths per 1000 PY (95% confidence interval [CI] 54.5-89.4). Most deaths were of infectious etiology, mostly related to HIV. In a modified intention-to-treat analysis, the impact of prerelease methadone on postrelease mortality was consistent with a null effect in unadjusted (hazard ratio [HR] 1.3, 95% CI 0.6-3.1) and covariate-adjusted (HR 1.2, 95% CI 0.5-2.8) models. Predictors of mortality were educational level (HR 1.4, 95% CI 1.0-1.8), pre-incarceration alcohol use (HR 2.0, 95% CI 1.1-3.9), and lower CD4+ T-lymphocyte count (HR 0.8 per 100-cell/mL increase, 95% CI 0.7-1.0). CONCLUSIONS: Postrelease mortality in this sample of men with HIV and OUD was extraordinarily high, and most deaths were likely of infectious etiology. No effect of prerelease methadone on postrelease mortality was observed, which may be due to study limitations or an epidemiological context in which inadequately treated HIV, and not inadequately treated OUD, is the main cause of death after prison release. TRIAL REGISTRATION: NCT02396979. Retrospectively registered 24/03/2015.

RESUMEN

OBJECTIVE: The objective of this study was to determine the availability and national distribution of HIV testing and counseling at substance use treatment facilities in the United States. METHODS: Analyses of data from the 2018 National Survey of Substance Abuse Treatment Services assessed HIV testing and counseling availability in U.S. substance use treatment facilities (excluding those in U.S. territories). Facilities were subcategorized by availability of mental health services and medication for opioid use disorders and compared by using logistic models. Descriptive statistics were calculated to characterize the availability of HIV testing and counseling by state, state HIV incidence, and facility characteristics. RESULTS: Among U.S. substance use treatment facilities (N=14,691), 29% offered HIV testing, 53% offered HIV counseling, 23% offered both, and 41% offered neither. Across states, the proportions of facilities offering HIV testing ranged from 9.0% to 62.8%, and the proportion offering counseling ranged from 19.2% to 83.3%. In only three states was HIV testing offered by at least 50% of facilities. HIV testing was significantly more likely to be offered in facilities that offered medication for opioid use disorder (48.0% versus 16.0% in those not offering such medication) or mental health services (31.2% versus 24.1% in those not offering such services). Higher state-level HIV incidence was related to an increased proportion of facilities offering HIV testing. CONCLUSIONS: Only three in 10 substance use treatment facilities offered HIV testing in 2018. This finding represents a missed opportunity for early identification of HIV among people receiving treatment for substance use disorders.

RESUMEN

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.

RESUMEN

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 < 0.001), and perceived need for medical 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 (ß = 0.21, 95% CI 0.01-0.40, p = 0.032) and methadone utilization (ß = 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.

RESUMEN

HIV testing services are the gateway into HIV treatment and are critical for monitoring the epidemic. HIV testing is recommended at least annually in high-risk populations, including people who inject drugs (PWID). In Malaysia, the HIV epidemic is concentrated among PWID, but their adherence to testing recommendations and the proportion of HIV-positive PWID who are aware of their status remain unknown. We recruited 460 PWID in Greater Kuala Lumpur using respondent-driven sampling and conducted HIV testing. We examined past testing behaviors, estimating testing frequency, correlates of testing in the past 12 months, and the proportion of those living with HIV who were aware of their status. Results showed that most PWID living with HIV (90.4%, 95% CI: 83.6%-95.9%) were aware of their status. Among those never previously diagnosed with HIV, few had accessed HIV testing in the past 12 months (14.3%, 95% CI: 11.1%-18.0%). Prison (57.0%) and compulsory drug detention centers (36.1%) were the primary locations where PWID reported ever being HIV tested, and the main correlate of recent testing in regression was recent criminal justice involvement. Although awareness of HIV status may be high among PWID living with HIV in Kuala Lumpur, testing occurs primarily in prisons and compulsory drug detention centers, where it is involuntary and linkage to care is limited. A shift in HIV testing policy is needed to align health and human rights objectives, replacing mandatory testing with voluntary testing in settings where individuals can be rapidly linked to HIV care.

RESUMEN

OBJECTIVES: HIV-related mortality is increasing in Indonesia, where prisons house many people living with HIV and addiction. We examined all-cause mortality in HIV-infected Indonesian prisoners within prison and up to 24 months post-release. MATERIALS AND METHODS: Randomly selected HIV-infected male prisoners (n=102) from two prisons in Jakarta, Indonesia completed surveys in prison and were followed up for 2 years (until study completion) or until they died or were lost to follow-up. Death dates were determined from medical records and interviews with immediate family members. Kaplan-Meier and Cox proportional hazards regression models were analyzed to identify mortality predictors. RESULTS: During 103 person-years (PYs) of follow-up, 15 deaths occurred, including ten in prison. The crude mortality rate within prison (125.2 deaths per 1,000 PYs) was surpassed by the crude mortality rate in released prisoners (215.7 deaths per 1,000 PYs). HIV-associated opportunistic infections were the most common probable cause of death. Predictors of within-prison and overall mortality were similar. Shorter survival overall was associated with being incarcerated within a specialized "narcotic" prison for drug offenders (hazard ratio [HR] 9.2, 95% confidence interval [CI] 1.1-76.5; P=0.03), longer incarceration (HR 1.06, 95% CI 1.01-1.1; P=0.01), and advanced HIV infection (CD4+ T-cell count<200cells/µL; HR 4.8, 95% CI 1.2-18.2; P=0.02). Addiction treatment was associated with longer survival (HR 0.1, 95% CI 0.01-0.9; P=0.03), although treatment with antiretroviral therapy (ART) or methadone was not. CONCLUSIONS: Mortality in HIV-infected prisoners is extremely high in Indonesia, despite limited provision of ART in prisons. Interventions to restore immune function with ART and provide prophylaxis for opportunistic infections during incarceration and after release would likely reduce mortality. Narcotics prisons may be especially high-risk environments for mortality, emphasizing the need for universal access to evidence-based HIV treatments.

RESUMEN

BACKGROUND: Sex workers face a disproportionate burden of human immunodeficiency virus (HIV) and sexually transmitted infections (STI) worldwide. For cisgender women sex workers (CWSW), global HIV prevalence is over 10%, whereas transgender women sex workers (TWSW) face an HIV burden of 19% to 27%. METHODS: We used respondent-driven sampling to recruit 492 sex workers, including CWSW (n = 299) and TWSW (n = 193) in Greater Kuala Lumpur, Malaysia. Participants completed an in-depth survey and were screened for HIV, syphilis, Chlamydia trachomatis, and Neisseria gonorrhoeae. Sample characteristics stratified by gender identity and interview site are presented. Bivariate analyses comparing CWSW and TWSW were conducted using independent samples t tests for continuous variables and χ tests for categorical variables. RESULTS: Pooled HIV prevalence was high (11.7%; 95% confidence interval [CI], 8.8-14.5), and was similar for CWSW (11.1%) and TWSW (12.4%). Rates of syphilis 25.5% (95% CI, 21.6-29.5), C. trachomatis (14.8%; 95% CI, 11.6-18.0) and N. gonorrhoeae (5.8%; 95% CI, 3.7-7.9) were also concerning. Both groups reported lifetime HIV testing (62.4%), but CWSW were less likely to have ever been HIV tested (54.5%) than TWSW (74.6%). Median time since last HIV test was 24 months. Previous screening for STI was low. Inconsistent condom use and drug use during sex work were not uncommon. CONCLUSIONS: High HIV and STI prevalence, coupled with infrequent HIV and STI screening, inconsistent condom use, and occupational drug use, underscore the need for expanded HIV and STI prevention, screening, and treatment efforts among CWSW and TWSW in Malaysia.

RESUMEN

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.

RESUMEN

Although it is well established that HIV-related stigma, depression, and lack of social support are negatively associated with health-related quality of life (HRQoL) among people living with HIV (PLH), no studies to date have examined how these psychosocial factors interact with each other and affect HRQoL among incarcerated PLH. We, therefore, incorporated a moderated mediation model (MMM) to explore whether depression mediates the effect of HIV-related stigma on HRQoL as a function of the underlying level of social support. Incarcerated HIV-infected men with opioid dependence (N = 301) were recruited from the HIV units in Kajang prison in Malaysia. Participants completed surveys assessing demographic characteristics, HIV-related stigma, depression, social support, and HRQoL. Results showed that the effect of HIV-related stigma on HRQoL was mediated via depression (a1:ß = 0.1463, p < 0.001; b1:ß = -0.8392, p < 0.001), as demonstrated by the two-tailed significance test (Sobel z = -3.8762, p < 0.001). Furthermore, the association between social support and HRQoL was positive (ß = 0.4352, p = 0.0433), whereas the interaction between HIV-related stigma and depression was negatively associated with HRQOL (ß = -0.0317, p = 0.0133). This indicated that the predicted influence of HIV-related stigma on HRQoL via depression had negative effect on HRQoL for individuals with low social support. The results suggest that social support can buffer the negative impact of depression on HRQoL and highlights the need for future interventions to target these psychosocial factors in order to improve HRQoL among incarcerated PLH.

RESUMEN

BACKGROUND: HIV is primarily concentrated among people who inject drugs (PWID) in Malaysia, where currently HIV prevention and treatment coverage is inadequate. To improve the targeting of interventions, we examined HIV clustering and the role that social networks and geographical distance play in influencing HIV transmission among PWID. METHODS: Data were derived from a respondent-driven survey sample (RDS) collected during 2010 of 460 PWID in greater Kuala Lumpur. Analysis focused on socio-demographic, clinical, behavioural, and network information. Spatial probit models were developed based on a distinction between the influence of peers (individuals nominated through a recruitment network) and neighbours (residing a close distance to the individual). The models were expanded to account for the potential influence of the network formation. RESULTS: Recruitment patterns of HIV-infected PWID clustered both spatially and across the recruitment networks. In addition, HIV-infected PWID were more likely to have peers and neighbours who inject with clean needles were HIV-infected and lived nearby (<5km), more likely to have been previously incarcerated, less likely to use clean needles (26.8% vs 53.0% of the reported injections, p<0.01), and have fewer recent injection partners (2.4 vs 5.4, p<0.01). The association between the HIV status of peers and neighbours remained significantly correlated even after controlling for unobserved variation related to network formation and sero-sorting. CONCLUSION: The relationship between HIV status across networks and space in Kuala Lumpur underscores the importance of these factors for surveillance and prevention strategies, and this needs to be more closely integrated. RDS can be applied to identify injection network structures, and this provides an important mechanism for improving public health surveillance, accessing high-risk populations, and implementing risk-reduction interventions to slow HIV transmission.

RESUMEN

Throughout Southeast Asia, repressive drug laws have resulted in high rates of imprisonment in people who inject drugs (PWID) and people living with HIV (PLH), greatly magnifying the harm associated with HIV, tuberculosis, and addiction. We review findings from Malaysia's largest prison to describe the negative synergistic effects of HIV, tuberculosis, addiction, and incarceration that contribute to a 'perfect storm' of events challenging public and personal health and offer insights into innovative strategies to control these converging epidemics. The majority of PLH who are imprisoned in Malaysia are opioid dependent PWID. Although promoted by official policy, evidence-based addiction treatment is largely unavailable, contributing to rapid relapse and/or overdose after release. Similarly, HIV treatment in prisons and compulsory drug treatment centers is sometimes inadequate or absent. The prevalence of active tuberculosis is high, particularly in PLH, and over 80 % of prisoners and prison personnel are latently infected. Mandatory HIV testing and subsequent segregation of HIV-infected prisoners increases the likelihood of tuberculosis acquisition and progression to active disease, amplifying the reservoir of infection for other prisoners. We discuss strategies to control these intersecting epidemics including screening linked to standardized treatment protocols for all three conditions, and effective transitional programs for released prisoners. For example, recently introduced evidence-based interventions in prisons like antiretroviral therapy (ART) to treat HIV, isoniazid preventive therapy to treat latent tuberculosis infection, and methadone maintenance to treat opioid dependence, have markedly improved clinical care and reduced morbidity and mortality. Since introduction of these interventions in September 2012, all-cause and HIV-related mortality have decreased by 50.0 % and 75.7 %, respectively. We discuss the further deployment of these interventions in Malaysian prisons.

RESUMEN

Negative attitudes toward HIV medications may restrict utilization of antiretroviral therapy (ART) in Indonesian prisons where many people living with HIV (PLH) are diagnosed and first offered ART. This mixed-method study examines the influence of medication attitudes on ART utilization among HIV-infected Indonesian prisoners. Randomly-selected HIV-infected male prisoners (n = 102) completed face-to-face in-depth interviews and structured surveys assessing ART attitudes. Results show that although half of participants utilized ART, a quarter of those meeting ART eligibility guidelines did not. Participants not utilizing ART endorsed greater concerns about ART efficacy, safety, and adverse effects, and more certainty that ART should be deferred in PLH who feel healthy. In multivariate analyses, ART utilization was independently associated with more positive ART attitudes (AOR = 1.09, 95 % CI 1.03-1.16, p = 0.002) and higher internalized HIV stigma (AOR = 1.03, 95 % CI 1.00-1.07, p = 0.016). Social marketing of ART is needed to counteract negative ART attitudes that limit ART utilization among Indonesian prisoners.

RESUMEN

The HIV epidemic in Malaysia is concentrated among people who inject drugs (PWID). Accurate estimates of HIV prevalence are critical for developing appropriate treatment and prevention interventions for PWID in Malaysia. In 2010, 461 PWID were recruited using respondent-driven sampling in Greater Kuala Lumpur, Malaysia. Participants completed rapid HIV testing and behavioral assessments. Estimates of HIV prevalence were computed for each of the three recruitment sites and the overall sample. HIV prevalence was 15.8 % (95 % CI 12.5-19.2 %) overall but varied widely by location: 37.0 % (28.6-45.4 %) in Kampung Baru, 10.3 % (5.0-15.6 %) in Kajang, and 6.3 % (3.0-9.5 %) in Shah Alam. Recruitment extended to locations far from initial interview sites but was concentrated around discrete geographic regions. We document the high prevalence of HIV among PWID in Greater Kuala Lumpur. Sustained support for community surveillance and HIV prevention interventions is needed to stem the HIV epidemic among PWID in Malaysia.

RESUMEN

Fishermen in Southeast Asia have been found to be highly vulnerable to HIV, with research evidence highlighting the role of sexual risk behaviors. This study aims to estimate the rate of HIV as well as hepatitis C virus (HCV) infections among Malaysian fishermen, and the risky sexual and injection drug use behaviors that may contribute to these infections. The study also includes an assessment of socio-demographic, occupational and behavioral correlates of testing positive for HIV or HCV, and socio-demographic and occupational correlates of risk behaviors. The study had a cross-sectional design and recruited 406 fishermen through respondent-driven sampling (RDS). Participants self-completed a questionnaire and provided biological specimens for HIV and HCV testing. We conducted and compared results of analyses of both unweighted data and data weighted with the Respondent-Driven Sampling Analysis Tool (RDSAT). Of the participating fishermen, 12.4% were HIV positive and 48.6% had HCV infection. Contrary to expectations and findings from previous research, most fishermen (77.1%) were not sexually active. More than a third had a history of injection drug use, which often occurred during fishing trips on commercial vessels and during longer stays at sea. Of the fishermen who injected drugs, 42.5% reported unsafe injection practices in the past month. Reporting a history of injection drug use increased the odds of testing HIV positive by more than 6 times (AOR = 6.22, 95% CIs [2.74, 14.13]). Most fishermen who injected drugs tested positive for HCV. HCV infection was significantly associated with injection drug use, being older than 25 years, working on a commercial vessel and spending four or more days at sea per fishing trip. There is an urgent need to strengthen current harm reduction and drug treatment programs for Malaysian fishermen who inject drugs, especially among fishermen who work on commercial vessels and engage in deep-sea fishing.

RESUMEN

BACKGROUND: Little is known about attitudes toward and experiences with opioid maintenance therapy (OMT) among people who inject drugs in Malaysia, a country where people who inject drugs comprise 1.3% of the adult population. METHODS: In 2010, 460 people who inject drugs in Greater Kuala Lumpur, Malaysia were surveyed to evaluate attitudes toward and experiences with OMT and treatment readiness. Attitudes towards OMT with both methadone and buprenorphine were assessed using an opinions scale. Multivariable linear regression was used to assess correlates of treatment readiness, measured with the 19-item Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES). RESULTS: All 460 participants used opioids and nearly all (99.1%) met criteria for opioid dependence. Few had had previous experience with methadone (9.3%) or buprenorphine (12.6%) maintenance therapy, yet many had used methadone (55.2%) or buprenorphine (51.7%) outside of treatment settings. Fifteen percent had injected buprenorphine in the past month, and of the few that were currently receiving buprenorphine maintenance therapy, almost all were injecting it. The majority of subjects exhibited a moderate level of treatment readiness and a preference for methadone over buprenorphine. Those with low treatment readiness scores were more likely to have previous experience with compulsory drug detention centers (p<0.01), needle/syringe exchange programs (p<0.005), or be of Indian ethnicity (p<0.001). Past use of methadone (p<0.01), older age (p<0.001), higher stress symptom severity (p<0.001), and sharing of needles or syringes (p<0.05) were associated with higher treatment readiness scores. CONCLUSION: There are suboptimal levels of OMT experience among people who inject drugs that may be improved by addressing factors that influence patient attitudes. Those individuals with moderate treatment readiness may be targeted by brief motivational and cognitive interventions in primary care, prisons or OMT clinics aimed at improving entry into and retention in treatment.
