Redressing the epidemics of opioid overdose and HIV among people who inject drugs in Central Asia: the need for a syndemic approach

A systematic review of the distribution of take-home naloxone in low- and middle-income countries and barriers to the implementation of take-home naloxone programs

Background

Opioid overdose epidemic is hitting record highs worldwide, accounting for 76% of mortality related to substance use. Take-home naloxone (THN) strategies are being implemented in many developed countries that suffer from high opioid overdose death rates. They aim to provide overdose identification and naloxone administration training, along with THN delivery to opioid users and others likely to witness an overdose incident such as family members and peers. However, little is known about such measures in low- and middle-income countries (LMIC), where opioid use and opioid-related deaths are reportedly high. This systematic literature review aims to examine the distribution of THN in LMIC, review studies identifying barriers to the implementation of THN programs worldwide, and assess their applicability to LMIC.

Methods

The literature was searched and analyzed for eligible studies with quality assessment.

Results

Two studies were found from LMIC on THN programs with promising results, and 13 studies were found on the barriers identified in implementing THN programs worldwide. The main barriers to THN strategies were the lack of training of healthcare providers, lack of privileges, time constraints, cost, legislative/policy restrictions, stigma, fear of litigation, and some misperceptions around THN.

Conclusions

The barriers outlined in this paper are probably applicable to LMIC, but more difficult to overcome considering the differences in their response to opioid overdose, their cultural attitudes and norms, the high cost, the waivers required, the legislative differences and the severe penalties for drug-related offenses in some of these countries. The solutions suggested to counter-act these obstacles can also be more difficult to achieve in LMIC. Further research is required in this area with larger sample sizes to provide a better understanding of the obstacles to the implementation, feasibility, accessibility, and utilization of THN programs in LMIC.

Toxic desomorphine encephalopathy due to the use of “Krokodil”: clinical and neuroimaging features

Background: Toxic desomorphine encephalopathy (TDE) is a pathological condition that develops as a result of the intravenous use of a drug called Krokodil containing desomorphine, made in the artisanal conditions using codeine-containing drugs, organic solvents (gasoline), iodine and red phosphorus. This disease is more often observed in the CIS countries. In addition to the acute and chronic pathological conditions with the damage to various organs, the use of Krokodil is characterized by pronounced extrapyramidal manifestations in the form of dystonia, parkinsonism, postural disorders, as well as the occurrence of cognitive and affective disorders. Aims: To find the clinical and neuroimaging features of toxic desomorphine encephalopathy, as well as possible methods of its treatment. Methods: A clinical analysis of the medical documentation of 21 TDE patients (11 women and 10 men) with a history of the use of Krokodil was carried out, the patients had been under observation from 2014 to 2021. All the patients underwent a clinical physical and neurological examination, 14 of them underwent neuroimaging (brain MRI and/or MSCT). The observation of these patients revealed a number of characteristic clinical and neuroimaging features inherent in the majority of drug addicts. Results: The clinical picture of patients with TDE was dominated by movement disorders. All the patients had pronounced postural disorders and gait disturbance. Parkinsonism was observed in 20 of 21 patients. The hyperkinetic syndrome was presented in 17 patients (80.9%) and was manifested by dystonia of various localization with polymorphic manifestations. The brain MRI data taken from the Krokodil users for 3 years were characterized by symmetrical focal changes in the basal ganglia, brainstem, cerebellum and internal capsule of the thalamus in the form of an increase in the intensity of the MR signal in the T1 mode and attenuation in the T2-weighted images mode (7 of 11 cases), with the subsequent regression of these characteristics based on the results of the subsequent MRI studies. Conclusion: The study results have revealed the clinical manifestations characteristic of TDE polymorphic extrapyramidal disorders, as well as neuroimaging changes reflecting these data.

More than saving lives: Qualitative findings of the UNODC/WHO Stop Overdose Safely (S-O-S) project

BACKGROUND

The Stop Overdose Safely (S-O-S) initiative-developed in compliance with WHO guidelines-aims to prevent opioid overdose deaths. Under the umbrella of this initiative a multi-country project was implemented in Kazakhstan, Kyrgyzstan, Tajikistan, and Ukraine, that involved overdose recognition and response training, including the provision of take-home naloxone (THN). More than 14,000 potential overdose witnesses were trained and more than 16,000 THN kits were distributed across the participating countries. This paper reports on the qualitative component of an evaluation aiming to understand the views and experiences of S-O-S project participants.

METHODS

Data were drawn from focus group discussions with 257 project participants from across all four countries, including people who use and inject drugs, and others likely to witness an opioid overdose. Data were analysed thematically.

RESULTS

Findings revealed how past experiences of trauma and loss related to overdose death were common, as was appreciation and gratitude for the opportunity to participate in the S-O-S training. Participants described how they shared knowledge and skills with others. Empowerment and destigmatising narratives featured prominently, and highlighted how for people who use drugs, feeling valued and cared about-not only by families and friends, but by health care providers, and sometimes police-was a positive outcome of their participation. Nevertheless, findings also revealed how real experiences of fear regarding police intervention was a barrier to carrying naloxone and intervening when faced with an overdose situation.

CONCLUSION

Our analysis found that the S-O-S project produced positive outcomes that go well beyond saving lives. Despite identifying barriers to THN uptake, our findings support a growing body of evidence that broad access to THN as part of a continuum of care can enhance the health and wellbeing of people who use drugs and their communities, in low- to middle-income countries.

Assessing HIV and overdose risks for people who use drugs exposed to compulsory drug abstinence programs (CDAP): A systematic review and meta-analysis

BACKGROUND

Evidence supports integrating drug use treatment, harm reduction, and HIV prevention services to address dual epidemics of drug use disorders and HIV. These dual epidemics have spurred a rise in legally-enforced compulsory drug abstinence programs (CDAP), despite limited evidence on its effectiveness. We conducted a systematic review and meta-analysis evaluating the association between CDAP exposure and HIV and overdose-related risk.

METHODS

We searched PubMed, EBSCOhost and Sociological Abstracts for studies that contained an individual-level association between CDAP exposure and related HIV or overdose risks, with no date restrictions. Meta-analyses were conducted on data abstracted from eligible studies, using pooled random-effects models and I-squared statistics. We assessed quality of the studies across 14 criteria for observational studies.

RESULTS

Out of 2,226 abstracts screened, we included 8 studies (5253 individuals/776 events) across China, Mexico, Thailand, Norway, and the United States. All but two were cross-sectional analyses, limiting strength of observed associations. In the two studies that reported association between CDAP and HIV seropositivity or receptive syringe sharing, findings were inconsistent and did not indicate that those with exposure to CDAP had increased odds of HIV or syringe sharing. However, we found the odds of experiencing non-fatal overdose in lifetime and in the last 6-12 months were 2.02 (95% CI 0.22 - 18.86, p = 0.16) to 3.67 times higher (95% CI 0.21 - 62.88, p = 0.39), respectively, among those with CDAP exposure than those without.

CONCLUSION

Research assessing HIV risk associated with CDAP is scant and inconclusive, while evidence of robust associations between CDAP and overdose risk continues to mount. More rigorous, longitudinal studies are needed to evaluate the causal relationships between CDAP and these health outcomes. Aside from the growing evidence base on collateral harms, ethical considerations dictate that voluntary, evidence-based drug treatment should be prioritized to address the drivers of excess morbidity and mortality among people who use drugs.

Cost-Effectiveness of an Opioid Abuse-Prevention Program Using the Narcotics Information Management System in South Korea

OBJECTIVES

To assess the cost-effectiveness of an opioid abuse-prevention program embedded in the Narcotics Information Management System ("the Network System to Prevent Doctor-Shopping for Narcotics") in South Korea.

METHODS

Using a Markov model with a 1-year cycle length and 30-year time horizon, we estimated the incremental cost-utility ratio (ICUR) of implementing an opioid abuse-prevention program in patients prescribed outpatient opioids from a Korean healthcare payer's perspective. The model has 6 health states: no opioid use, therapeutic opioid use, opioid abuse, overdose, overdose death, and all-cause death. Patient characteristics, healthcare costs, and transition probabilities were estimated from national population-based data and published literature. Age- and sex-specific utilities of the general Korean population were used for the no-use state, whereas the other health-state utilities were obtained from published studies. Costs (in 2019 US dollars) included the expenses of the program, opioids, and overdoses. An annual 5% discount rate was applied to the costs and quality-adjusted life-years (QALYs). Parameter uncertainties were explored via deterministic and probabilistic sensitivity analyses.

RESULTS

The program was associated with 2.27 fewer overdoses per 100 000 person-years, with an ICUR of $227/QALY. The ICURs were generally robust to parameter changes, although the program's effect on abuse reduction was the most influential parameter. Probabilistic sensitivity analysis showed that the program reached a 100% probability of cost-effectiveness at a willingness-to-pay threshold of $900/QALY.

CONCLUSIONS

The opioid abuse-prevention program appears to be cost-effective in South Korea. Mandatory use of the program should be considered to maximize clinical and economic benefits of the program.

Using syndemic theory to understand food insecurity and diet-related chronic diseases

Syndemic Theory (ST) provides a framework to examine mutually enhancing diseases/health issues under conditions of social inequality and inequity. ST has been used in multiple disciplines to address interacting infectious diseases, noncommunicable diseases, and mental health conditions. The theory has been critiqued for its inability to measure disease interactions and their individual and combined health outcomes. This article reviews literature that strongly suggests a syndemic between food insecurity (FI) and diet-related chronic diseases (DRCDs), and proposes a model to measure the extent of such interaction. The article seeks to: (1) examine the potential syndemic between FI and DRCDs; (2) illustrate how the incorporation of Life History Theory (LHT), into a syndemic framework can help to highlight critical lifeperiods when FI-DRCD interactions result in adverse health outcomes; (3) discuss the use of mixed methods to identify and measure syndemics to enhance the precision and predictive power of ST; and (4) propose an analytical model for the examination of the FI-DRCD syndemic through the life course. The proposed model is more relevant now given the significant increase in FI globally as a result of the ongoing COVID-19 pandemic. The differential impact that the pandemic appears to have among various age groups and by other demographic factors (e.g., race, gender, income) offers an opportunity to examine the potential FI-DRCD syndemic under the lens of LHT.

The protective effect of trusted dealers against opioid overdose in the U.S

BACKGROUND

Opioid overdose has become the leading cause of death among adults between 25 and 54 years old in the U.S. The purpose of this study is to explore the social and relational factors that shape the current opioid overdose epidemic.

METHODS

Between January 2016 and February 2017, adults in Providence, Rhode Island, who use opioids were recruited to complete structured survey and semi-structured interview about the social context of their substance use.

RESULTS

A total of 92 individuals completed a survey and an interview. Of those, 51 individuals (68.6% male, 49.0% white) discussed their relationships with drug suppliers in their interview and were included in this sub-study. Many of these participants indicated that long-term relationships with trusted dealers represent a key strategy for reducing the risk of substance use-related harm due to suppliers' alleged adoption of consumer protection strategies (e.g. refusing to sell fentanyl) and quality assurance measures (e.g. testing batches of drugs for fentanyl prior to sale).

CONCLUSION

Interpersonal relationships between individuals who use drugs and their suppliers strongly influence the risk and protective factors experienced by people who use drugs in today's opioid overdose epidemic. Evidence-based prevention strategies that are based on an awareness of-or even designed to harness-those positive and/or protective relationships that people who use drugs have already constructed for themselves are likely merited.

Association of History of Injection Drug Use with External Cause-Related Mortality Among Persons Linked to HIV Care in an Urban Clinic, 2001-2015

High mortality rates among persons with HIV with a history of injection drug use (PWID) are thought to be driven in part by higher rates of external cause-related mortality. We followed 4796 persons aged 18-70 engaged in continuity HIV care from 2001 to 2015 until death or administrative censoring. We compared cause-specific (csHR) and subdistribution hazards (sdHR) of death due to external causes among PWID and persons who acquired their HIV infection through other routes (non-IDU). We standardized estimates on age, sex, race, and HIV-related health status. The standardized csHR for external cause-related death was 3.57 (95% CI 2.39, 5.33), and the sdHR was 3.14 (95% CI 2.16, 4.55). The majority of external cause-related deaths were overdose-related and standardized sdHR was 4.02 (95% CI 2.40, 6.72). Absolute rate of suicide was low but the csHR for PWID compared to non-IDU was most elevated for suicide (6.50, 95% CI 1.51, 28.03). HIV-infected PWID are at a disproportionately increased risk of death due to external causes, particularly overdose and suicide.

Opioid epidemic and liver disease

Opioid use in the United States and in many parts of the world has reached epidemic proportions. This has led to excess mortality as well as significant changes in the epidemiology of liver disease. Herein, we review the impact of the opioid epidemic on liver disease, focusing on the multifaceted impact this epidemic has had on liver disease and liver transplantation. In particular, the opioid crisis has led to a significant shift in incident hepatitis C virus infection to younger populations and to women, leading to changes in screening recommendations. Less well characterized are the potential direct and indirect hepatotoxic effects of opioids, as well as the changes in the incidence of hepatitis B virus infection and alcohol abuse that are likely rising in this population as well. Finally, the opioid epidemic has led to a significant rise in the proportion of organ donors who died due to overdose. These donors have led to an overall increase in donor numbers, but also to new considerations about the better use of donors with perceived or actual risk of disease transmission, especially hepatitis C. Clearly, additional efforts are needed to combat the opioid epidemic. Moreover, better understanding of the epidemiology and underlying pathophysiology will help to identify and treat liver disease in this high-risk population.

Overdose mortality rates in Croatia and factors associated with self-reported drug overdose among persons who inject drugs in three Croatian cities

BACKGROUND

Drug overdose is the major cause of morbidity and mortality among persons who inject drugs (PWID). We assessed factors associated with the non-fatal drug overdose among PWID in three Croatian cities and national trends of overdose-related mortality (OM), and rates of uptake of opioid agonist drug treatment (OAT).

METHODS

We used a respondent-driven sampling method to recruit 830 PWID in Zagreb, Split and Rijeka in 2014/2015. Participants completed behavioural questionnaires that included questions about overdose history, and we used Poisson regression to assess factors associated with self-reported overdose. We used joinpoint regression to calculate national trends of OM from 2001 to 2015 and rates of uptake of drug treatment from 2005 to 2015.

RESULTS

Lifetime prevalence of self-reported drug overdose in our RDS sample was 45.2%, while 4.1% of PWID reported overdose in the past 12 months; PWID who injected more than one type of drug in the past 12 months (adjusted prevalence ratio [aPR] = 4.56, 95% confidence intervals [CI] = 1.35-15.38) compared to injecting only heroin, and those enrolled in OAT (aPR = 1.94, 95% CI = 1.01-3.74) were more likely to report overdose in the past 12 months. We observed an increase in annual percent change (APC) of the national OM rates from 2001 to 2007 (APC = 22.5%, 95% CI = 16.3-29.0) and a decline from 2007 to 2015 (APC = -8.0%, 95% CI = -5.3- -10.5). The national rates of drug treatment enrollment increased from 2005 to 2010 (APC = 12.0%, 95% CI = 10.3-13.8), mostly due to increase in provision of buprenorphine from 2005 to 2008 (APC = 130.4%, 95% CI = 102.1-162.7).

CONCLUSION

Injecting more than one type of drugs and enrollment in OAT while still injecting drugs was positively associated with non-fatal overdose in our sample. To further reduce OM in Croatia we suggest improvements in coverage and delivery of OAT and establishment of provision of naloxone for PWID.

Intimate relationships and patterns of drug and sexual risk behaviors among people who inject drugs in Kazakhstan: A latent class analysis

BACKGROUND

Multiple drug and sexual risk behaviors among people who inject drugs (PWID) in intimate relationships increase the risk of HIV and HCV transmission. Using data on PWID in intimate partnerships in Almaty, Kazakhstan, this study performed latent class analysis (LCA) on drug and sexual risk behaviors and estimated associations between dyadic relationship factors and membership in latent classes.

METHODS

LCA was performed on a sample of 510 PWID (181-females/FWID, 321-males/MWID) to identify levels of drug and sexual risk behaviors. Generalized structural equation modeling with multinomial regressions estimated associations between relationship factors (length risk reduction communication, risk reduction self-efficacy) and class membership after adjusting for substance use severity, overdose, depression, binge drinking, intimate partner violence, structural factors, and sociodemographic characteristics. Models were sex-stratified to include FWID and PWID.

RESULTS

A 3-class model best fit the data and consisted of low, medium, and high-risk classes. GSEM found that greater injection self-efficacy was associated with a lower likelihood of membership in the high-risk class for PWID and FWID. For MWID, greater length of the relationship was associated with a lower likelihood of membership in the medium-risk class. Greater relationship communication was associated with increased risk of membership in the high-risk latent class for MWID.

CONCLUSIONS

Future research must investigate if increasing risk reduction and safe sex self-efficacy could reduce drug and sexual risk behaviors and HIV transmission among PWID and their intimate partners. Interventions are needed that reduce power inequities within relationships as a method of increasing self-efficacy, particularly among women.

Differences by sex in associations between injection drug risks and drug crime conviction among people who inject drugs in Almaty, Kazakhstan

BACKGROUND

The criminalization of drug use leads to high rates of drug crime convictions for engaging in injection drug use behaviors, introducing barriers to HIV prevention and drug treatment for PWID. Females (FWID) face unique vulnerabilities to HIV compared to males (MWID) in Kazakhstan. This study examined sex differences in associations between HIV/HCV infection, HIV knowledge, injection drug risk behaviors, and conviction for a drug crime in a sample of people who inject drugs (PWID) in Almaty, Kazakhstan.

METHODS

Analyses were performed on baseline data from 510 PWID and stratified by males (MWID) (329) and females (FWID) (181) from Kazakhstan in a couples-focused HIV prevention intervention. Logistic regression analyses using mixed effects (AOR) examined associations between HIV/HCV infection, HIV knowledge, injection drug risk behaviors, drug use severity, drug treatment history and conviction for a drug crime.

RESULTS

About three quarters of PWID reported drug crime conviction (73.92%, n = 377). HCV infection was associated with increased odds of drug crime conviction for FWID (AOR = 4.35, CI95 = 1.83-10.31, p < .01) and MWID (AOR = 3.62, CI95 = 1.09-12.07, p < .01). HIV transmission knowledge was associated with increased odds of conviction for MWID (AOR = 1.19, CI95 = 1.00-1.41, p < .05). Injection drug risk knowledge was associated with lower odds of conviction (AOR = .75, CI95 = .59-.94, p < .05) for FWID. Receptive syringe sharing (AOR = 3.48, CI95 = 1.65-7.31, p < .01), splitting drug solutions (AOR = 4.12, CI95 = 1.86-7.31, p < .05), and injecting with more than two partners (AOR = 1.89, CI95 = 1.06-3.34, p < .05) was associated with increased odds of conviction for FWID. Receptive syringe or equipment sharing with intimate partners was associated with conviction for both MWID (AOR = 1.90, CI95 = 1.03-3.92, p < .05) and FWID (AOR = 1.95, CI95 = 1.02-3.70, p < .05). For FWID, injection drug use in public spaces was associated with conviction (AORME = 3.25, CI95 = 1.31-7.39, p < .01). Drug use severity was associated with increased odds of conviction for FWID (AOR = 1.29, CI95 = 1.09-1.53, p < .001) and MWID (AOR = 1.24, CI95 = 1.09-1.41, p < .001). Ever receiving drug treatment was associated with conviction for MWID (AOR = 2.31, CI95 = 1.32-4.12, p < .01).

CONCLUSION

High-risk behaviors, HCV infection and more severe substance use disorders are associated with drug crime conviction for PWID, particularly FWID. Structural interventions are necessary to increase the engagement of PWID with drug crime convictions in HIV prevention and substance abuse treatment.

The prescription opioid epidemic: a review of qualitative studies on the progression from initial use to abuse

Most research designed to answer the “why” of the prescription opioid epidemic has relied on structured interviews, which rigidly attempt to capture the complex reasons people use opioids. In contrast this systematic literature review focuses on peer-reviewed studies that have used a qualitative approach to examine the development of an opioid-use disorder from the point of initial exposure. Rather than simply providing a “high,” opioids reportedly relieve psychological/emotional problems or provide an escape from life stressors. As use continues, avoidance of withdrawal sickness becomes an overriding concern, with all other benefits playing minor roles in persistent use. These studies indicate that terms used in structured interviews, such as “nontherapeutic use” or variations thereof, poorly capture the complex range of needs opioids satisfy. Both quantitative/structured studies and more qualitative ones, as well as more focused studies, have an important role in better informing prevention and treatment efforts.

Reducing opioid overdose in Kazakhstan: A randomized controlled trial of a couple-based integrated HIV/HCV and overdose prevention intervention "Renaissance"

OBJECTIVES

To evaluate the efficacy of a couple-based integrated HIV/HCV and overdose prevention intervention on non-fatal and fatal overdose and overdose prevention behaviors among people who use heroin or other opioids in Almaty, Kazakhstan.

METHODS

We selected 479 participants who reported lifetime heroin or opioid use from a sample of 600 participants (300 couples) enrolled in a randomized controlled trial (RCT) conducted between May 2009 and February 2013. Participants were randomized to either (1) a 5-session couple-based HIV/HCV and overdose prevention intervention condition or (2) a 5-session Wellness Promotion and overdose prevention comparison condition. We used multilevel mixed-effects model with modified Poisson regression to estimate effects of the intervention as risk ratios (RR) and the corresponding 95% CIs.

RESULTS

About one-fifth (21.9%) of the sample reported that they had experienced an opioid overdose in the past 6 months at baseline. At the 12-month follow-up, both the intervention and comparison conditions reported significant reductions in non-fatal overdose and injection heroin/opioid use and significant increases in drug treatment attendance and naloxone use to prevent death from overdose. However, we found no differences between the study arms on any of these outcomes. There were three intervention condition participants (1.3%), compared to seven comparison condition participants (2.9%) who died from opioid overdose during the 12-month follow up period although this difference was not significant.

DISCUSSION

There were no significant conditions on any outcomes: both conditions showed promising effects of reducing non-fatal overdose and overdose risks. Integrating overdose prevention into a couple-based HIV/HCV intervention may be an efficient strategy to target the syndemic of opioid overdose, HIV and HCV in Kazakhstan.

Between Synergy and Travesty: A Sexual Risk Syndemic Among Pregnant Latina Immigrant and Non-immigrant Adolescents

Substance use, intimate partner violence, and depression contribute to sexual risk individually, yet have not been evaluated as a syndemic for adolescents. Using data from 772 pregnant Latina adolescents, we evaluated these factors as a syndemic and tested the moderating role of immigration. Bivariate analyses showed syndemic score (OR = 1.40, p = 0.02) and severity (OR = 1.68, p = 0.006) were predictors for multiple sex partners, and syndemic score predicting STIs (OR = 1.15, p = 0.05). Syndemic severity remained significant in multivariate analyses for multiple sex partners (OR = 1.53, p = 0.04). Moderation analyses showed higher syndemic severity was associated with more condom use among immigrants (OR = 1.75, p = 0.04) and less condom use (OR = 0.07, p = 0.011) among those with separated orientation. Higher syndemic severity also predicted greater odds for multiple partners (OR = 2.40, p = 0.01) among immigrants. This evidence suggests a sexual risk syndemic exists among Latina adolescents. Research should continue exploring this phenomenon, particularly exploring the role immigration plays for sexual health.

Social Determinants of HIV/HCV Co-Infection: A case Study from People Who Inject Drugs in Rural Puerto Rico

•

Co-infection correlates with age, longer period of drug use, medical insurance coverage and sexual identity.

•

LGBT PWID are vulnerable to co-infection. Stigma, commercial sex and violence compounds risk.

•

Culturally sensitive prevention strategies focused on this particular population should be implemented to avoid co-infection.

Intersecting epidemics of HIV, HCV, and syphilis among soon-to-be released prisoners in Kyrgyzstan: Implications for prevention and treatment

BACKGROUND

Central Asia is afflicted with increasing HIV incidence, low antiretroviral therapy (ART) coverage and increasing AIDS mortality, driven primarily by people who inject drugs (PWID). Reliable data about HIV, other infectious diseases, and substance use disorders in prisoners in this region is lacking and could provide important insights into how to improve HIV prevention and treatment efforts in the region.

METHODS

A randomly sampled, nationwide biobehavioural health survey was conducted in 8 prisons in Kyrgyzstan among all soon-to-be-released prisoners; women were oversampled. Consented participants underwent computer-assisted, standardized behavioural health assessment surveys and testing for HIV, HCV, HBV, and syphilis. Prevalence and means were computed, and generalized linear modelling was conducted, with all analyses using weights to account for disproportionate sampling by strata.

RESULTS

Among 381 prisoners who underwent consent procedures, 368 (96.6%) were enrolled in the study. Women were significantly older than men (40.6 vs. 36.5; p=0.004). Weighted prevalence (%), with confidence interval (CI), for each infection was high: HCV (49.7%; CI: 44.8-54.6%), syphilis (19.2%; CI: 15.1-23.5%), HIV (10.3%; CI: 6.9-13.8%), and HBV (6.2%; CI: 3.6-8.9%). Among the 31 people with HIV, 46.5% were aware of being HIV-infected. Men, compared to women, were significantly more likely to have injected drugs (38.3% vs.16.0%; p=0.001). Pre-incarceration and within-prison drug injection, primarily of opioids, was 35.4% and 30.8%, respectively. Independent correlates of HIV infection included lifetime drug injection (adjusted odds ratio [AOR]=38.75; p=0.001), mean number of years injecting (AOR=0.93; p=0.018), mean number of days experiencing drug problems (AOR=1.09; p=0.025), increasing duration of imprisonment (AOR=1.08; p=0.02 for each year) and having syphilis (AOR=3.51; p=0.003), while being female (AOR=3.06; p=0.004) and being a recidivist offender (AOR=2.67; p=0.008) were independently correlated with syphilis infection.

CONCLUSION

Drug injection, syphilis co-infection, and exposure to increased risk during incarceration are likely to be important contributors to HIV transmission among prisoners in Kyrgyzstan. Compared to the community, HIV is concentrated 34-fold higher in prisoners. A high proportion of undiagnosed syphilis and HIV infections presents a significant gap in the HIV care continuum. Findings highlight the critical importance of evidence-based responses within prison, including enhanced testing for HIV and sexually transmitted infections, to stem the evolving HIV epidemic in the region.

Policy responses to HIV/AIDS in Central Asia

The countries of Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) are confronted with one of the fastest growing HIV/AIDS epidemics worldwide, largely driven through injecting drug use. This article, based on a review of academic and grey literature, explores how they have responded. We find major similarities and differences across the region. At one extreme is Turkmenistan, which denies that there is any problem, does not offer harm reduction services or HIV/AIDS treatment and does not report any meaningful data to the international community. Uzbekistan is also pretty closed to outside influences, has discontinued its opioid substitution project and shares with Turkmenistan the legal prohibition of male-to-male sex. Kyrgyzstan originally led many progressive approaches in the region and, like neighbouring Tajikistan, has received substantial assistance by international agencies, in particular the Global Fund. Kazakhstan, with a much higher gross domestic product per capita, has taken on the financing of harm reduction activities through its national budget and has liberalised its drug policies. Yet, across the region punitive approaches to injecting drug use and people living with HIV/AIDS persist as do stigma and discrimination, while coverage with harm reduction programmes and treatment services is still low although with substantial variation across countries.

"There's nothing here": Deindustrialization as risk environment for overdose

BACKGROUND

Applying the "risk environment" approach proposed by Rhodes (2002, 2009), this study considers the diverse contextual factors contributing to drug overdose in a deindustrialized region of the United States. The Monongahela Valley of Pennsylvania, once a global center of steel production, has suffered a mass exodus of jobs, residents, and businesses since a national manufacturing crisis erupted in the early 1980s; more recently, it has seen a dramatic uptick in accidental drug poisoning deaths. Where recent local and national media attention to overdose has focused on suburban areas and middle class victims, this study concentrates instead on the deteriorating mill city of McKeesport, Pennsylvania.

METHODS

Eighteen clients of the city's sole drug treatment facility participated in in-depth interviews concerning their direct experience with accidental overdose. Specifically, participants were asked to describe their own most recent overdose event and/or the last overdose they had personally witnessed. They were also asked to speculate upon the roots of the local overdose epidemic, while venturing possible remedies.

RESULTS

In relating their overdose experiences, participants characterized a micro-level risk environment that was hidden behind closed doors, and populated by unprepared, ambivalent overdose "assistants." Tasked with explaining a geographic concentration of overdose in and around McKeesport, interviewees referenced the hopelessness of the area and its lack of opportunity as driving the use of heroin, with many explicitly suggesting the need for jobs and community reinvestment to reduce fatalities.

CONCLUSION

While state and county efforts to ameliorate overdose mortality have focused upon creating an open market in naloxone, this study suggests the need for interventions that address the poverty and social isolation of opiate users in the post-industrial periphery.

HIV prevention and treatment strategies can help address the overdose crisis

Since the 1990s, effective HIV prevention and treatment strategies have been coordinated and implemented in the United States, resulting in substantial reductions in HIV-related death and HIV transmission among people who use injection drugs. During the same period, despite substantial long-term funding of War on Drugs policies, opioid addiction, driven by increased prescription opioid use and heroin accessibility, has made overdose the leading cause of accidental injury death in the United States. This commentary describes how the prevention and treatment successes among people who use drugs in the HIV/AIDS epidemic can be applied to address the opioid overdose crisis.

Endogenous opiates and behavior: 2013

This paper is the thirty-sixth consecutive installment of the annual review of research concerning the endogenous opioid system. It summarizes papers published during 2013 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides, opioid receptors, opioid agonists and opioid antagonists. The particular topics that continue to be covered include the molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors related to behavior, and the roles of these opioid peptides and receptors in pain and analgesia; stress and social status; tolerance and dependence; learning and memory; eating and drinking; alcohol and drugs of abuse; sexual activity and hormones, pregnancy, development and endocrinology; mental illness and mood; seizures and neurologic disorders; electrical-related activity and neurophysiology; general activity and locomotion; gastrointestinal, renal and hepatic functions; cardiovascular responses; respiration and thermoregulation; and immunological responses.
