Stalled scale-up of opioid agonist therapies for HIV prevention in Kazakhstan: history, policy, and recommendations for change
HIV incidence and mortality are increasing in Eastern Europe and Central Asia and are concentrated in people who inject drugs. Maintenance with opioid agonist therapies (OAT) like methadone or buprenorphine is the best treatment for opioid use disorder and a key HIV-prevention strategy in the region. In Kazakhstan, the scale-up of methadone has been minimal since methadone’s introduction in 2008 and has been supported through international charitable organizations. As the Republic of Kazakhstan is designated to assume financial and administrative oversight of OAT, legislative gains can ensure treatment continuity and scale-up. Here, we review legislative barriers to OAT scale-up in Kazakhstan using an implementation science lens. We review legislative, political, and cultural barriers that undermine the efficient distribution and allocation of medications and impose burdensome clinical and administrative demands on patients and clinicians. Legislative reform is required to support further OAT expansion. We therefore provide policy recommendations to overcome these barriers to increase access to this life-saving, life-prolonging, evidence-based medical treatment. Minimally, these include increased numbers of clinical sites and patients at these sites; re-engineering OAT delivery across the country and directly to patients; introducing newer formulations of OAT; and creating an open bidding process to procure treatment medications

Knowledge and attitudes towards ambulatory treatment of tuberculоsis in Kazakhstan
Background
Ambulatory based treatment of tuberculosis has been recently introduced in Kazakhstan. We sought to assess the attitudes of the general population, TB patients and their household members towards ambulatory TB treatment and identify how knowledge of TB is associated with these attitudes.
Methods
New pulmonary TB cases and their household and community controls were recruited from three regions of Kazakhstan in 2012–2014. 1083 participants completed audio computer-assisted self interviews to assess their knowledge of TB and attitudes towards ambulatory care. Mixed effects logistic regression models were used to identify factors associated with attitudes toward ambulatory TB treatment.
Results
The proportion of people who considered ambulatory TB treatment as appropriate was very low (24.9%). Positive attitudes towards ambulatory TB treatment were significantly associated with region of residence, higher level of education, family support and experience with TB. The association between sufficient tuberculosis knowledge and favorable attitude toward ambulatory treatment was stronger among community controls compared to TB patients and their family members.
Conclusions
This study provides insight into attitudes toward ambulatory TB treatment among different groups and the specific influence of TB knowledge on these attitudes. Our findings can inform the process of integration of new TB treatment strategies and the development of appropriate education and advocacy programs in the general population
Vitamin D Receptor Gene Polymorphisms in Susceptibility to Tuberculosis in the Kazakh Population in Almaty and Almaty Area
Introduction: Vitamin D receptor (VDR) plays an important role in activating the immune response against various infectious agents. It is known that the active metabolite of ligand receptor Vitamin D (1,25 – dihydroxyvitamin D) is encoded by VDR and helps mononuclear phagocytes to suppress the intracellular growth of M. tuberculosis. The VDR gene harbors approximately 200 polymorphisms, some of which are linked to differences in receptor Vitamin D uptake and therefore can be considered as candidate disease risk variants. The relation between VDR gene polymorphisms and susceptibility to TB has been studied in different populations. There is not a great deal of information regarding the association of these SNPs with TB risk in the Kazakh population. The four most commonly investigated VDR polymorphisms in association with different diseases, including susceptibility to tuberculosis, are located in exon 2 (rs2228570 or FokI), intron 8 (rs1544410 or BsmI and rs7975232 or ApaI), and exon 9 (rs731236 or TaqI). The aim of our study was to determine whether these four VDR gene single nucleotide polymorphisms were associated with TB and whether they were a risk for the development of TB in the Kazakh Population in Almaty city and Almaty area.Methods: This study was a hospital-based case-control analysis of 283 individuals (99 TB patients and 184 healthy controls). Genotyping was performed by Taqman SNP allelic discrimination using commercial TaqMan SNP Genotyping assays. Statistical analysis was conducted using SPSS Version 19.0 software.Results: Genotype frequencies for the Kazakh population are close to world (HapMap) data on Asian populations. FokI and ApaI polymorphisms genotypes tend to be associated with TB risk under the co-dominant model [OR=1.18; 95%CI: (0.68, 2.07), p=0.15] for FokI and [OR=1.33; 95%CI: (0.61, 2.91), p=0.6] for ApaI. No significant association between the disease and TaqI, BsmI genotypes was observed.Conclusions: In summary, we explored potential associations between SNPs in the VDR (FokI, ApaI) gene and susceptibility to tuberculosis in the Kazakh Population, which requires further detailed analysis with a larger sample size and greater geographic diversity including other regions of Kazakhstan
Implications of Mobility Patterns and HIV Risks for HIV Prevention Among Migrant Market Vendors in Kazakhstan
Objectives. We examined the relationships between mobility characteristics and sexual risk behaviors among male and female migrant market vendors in Almaty, Kazakhstan. Methods. Participants completed a structured interview covering sociodemographics, mobility characteristics, sexual behaviors, and biomarkers for HIV, HCV, and syphilis. We used multivariate analyses to examine associations between mobility patterns and HIV risks after adjusting for sociodemographics. Results. Longer duration of a participant's last trip outside Almaty increased the odds of reporting multiple sexual partners. More frequent travel to visit family or friends was associated with multiple sexual partners and unprotected sex with steady partners. More frequent travel to buy goods in the past year was associated with multiple sexual partners. Men who traveled more often to buy goods were more likely to have purchased sex within the previous 90 days. Conclusions. Relationships between mobility patterns and sexual risk behaviors underscore the need for HIV-prevention strategies targeting the specific transmission dynamics that migrant vendors are likely to present

The Financial Lives and Capabilities of Women Engaged in Sex Work: Can Paradoxical Autonomy Inform Intervention Strategies?
INTRODUCTION- Despite growing attention to structural approaches to HIV prevention, including economic empowerment interventions for key populations, few studies examine the financial lives of women engaged in sex work (WESW) and even fewer examine the financial lives of those who also use drugs. The purpose of this paper is to examine the financial status, sex work involvement, and individual and structural vulnerabilities of women involved in sex work and drug use in Kazakhstan. METHODS- We used baseline data from Project Nova, a cluster-randomized controlled trial that tested the efficacy of a combined HIV risk reduction and microfinance intervention for WESW in two cities in Kazakhstan. We collected data on income, savings, debt, sex work, drug use, homelessness, food insecurity, HIV status, attitudes towards safety, and financial knowledge from 400 participants through computer-assisted self-interview techniques. Descriptive statistics were utilized to describe and characterize the sample and aforementioned measures. RESULTS- Findings illustrate the paradoxical nature of sex work, wherein women may achieve economic independence despite the great adversities they encounter in their daily lives and work. The majority of women (65%) in this study reported being the highest income earner in the household, caring for up to 3 dependents, and demonstrated entrepreneurial characteristics and aspirations for the future. However, many were still living below the poverty line (72.5%), as well as experiencing high levels of homelessness (58%) and food insecurity (89.5%). CONCLUSION- Study findings underscore the need for better understanding of the existing capabilities of WESW and those who use drugs, including financial autonomy and community supports, that may guide the design of programs that most effectively promote women’s economic well-being and ensure that it is not at the expense of wellness and safety. Designing such programs requires incorporating a social justice lens into social work and public health interventions, including HIV prevention, and attention to the human rights of the most marginalized and highest risk populations, including WESW and those who use drugs

Association of gender-based violence with sexual and drug-related HIV risk among female sex workers who use drugs in Kazakhstan
Background: Little is known about the prevalence of intimate partner violence (IPV) or client violence, and associated HIV risk among women who engage in sex work (WESW) and use drugs in Kazakhstan, despite a growing HIV epidemic. Methods: Women who reported engaging in sex work and using illicit drugs were recruited from Almaty and Temirtau, Kazakhstan between 2015 and 2017. A cross-sectional analysis was conducted to determine prevalence and correlates of physical and sexual violence perpetrated by intimate partners and clients. Associations between each type of violence with sexual and drug-related HIV risk behaviors were assessed with negative-binomial and logistic regression models, respectively. Results: Of the 400 women, 45% and 28% reported recent IPV and client violence, respectively. IPV and client violence was associated with a greater number of sex work clients [IPV: adjusted incidence rate ratio (aIRR)physical: 1.86, 1.28–2.71; aIRRsexual: 2.28, 1.56–3.35]; [client violence: aIRRphysical: 2.20, 1.44–3.42; aIRRsexual: 2.54, 1.72–3.83], and client violence was associated with greater frequency of condomless sex with clients [aIRRphysical: 2.33, 1.41–4.03; aIRRsexual: 2.16, 1.35–3.56]. Violence was not associated with injection drug use, despite exchanging sex for drugs being associated with higher odds of violence. Conclusion: HIV prevention programs for WESW in Kazakhstan should consider multi-sectoral approaches that address economic hardship and relationship-based components, in addition to violence reduction
Identifying risk factors associated with smear positivity of pulmonary tuberculosis in Kazakhstan
Background
Sputum smear-positive tuberculosis (TB) patients have a high risk of transmission and are of great epidemiological and infection control significance. Little is known about the smearpositive populations in high TB burden regions, such as Kazakhstan. The objective of this study is to characterize the smear-positive population in Kazakhstan and identify associated modifiable risk factors.
Methods
Data on incident TB cases’ (identified between April 2012 and March 2014) socio-demographic, risk behavior, and comorbidity characteristics were collected in four regions of Kazakhstan through structured survey and medical record review. We used multivariable logistic regression to determine factors associated with smear positivity.
Results
Of the total sample, 193 (34.3%) of the 562 study participants tested smear-positive. In the final adjusted multivariable logistic regression model, sex (adjusted odds ratio (aOR) = 2.0, 95% CI:1.3–3.1, p < 0.01), incarceration (aOR = 3.6, 95% CI:1.2–11.1, p = 0.03), alcohol dependence (aOR = 2.6, 95% CI:1.2–5.7, p = 0.02), diabetes (aOR = 5.0, 95% CI:2.4–10.7, p < 0.01), and physician access (aOR = 2.7, 95% CI:1.3–5.5p < 0.01) were associated with smear-positivity.
Conclusions
Incarceration, alcohol dependence, diabetes, and physician access are associated with smear positivity among incident TB cases in Kazakhstan. To stem the TB epidemic, screening, treatment and prevention policies should address these factors

The Silk Road Health Project: How Mobility and Migration Status Influence HIV Risks among Male Migrant Workers in Central Asia
Objectives
We examined whether mobility, migrant status, and risk environments are associated with sexually transmitted infections (STIs) and HIV risk behaviors (e.g. sex trading, multiple partners, and unprotected sex).
Methods
We used Respondent Driven Sampling (RDS) to recruit external male migrant market vendors from Kyrgyzstan, Uzbekistan, and Tajikistan as well internal migrant and non-migrant market vendors from Kazakhstan. We conducted multivariate logistic regressions to examine the effects of mobility combined with the interaction between mobility and migration status on STIs and sexual risk behaviors, when controlling for risk environment characteristics.
Results
Mobility was associated with increased risk for biologically-confirmed STIs, sex trading, and unprotected sex among non-migrants, but not among internal or external migrants. Condom use rates were low among all three groups, particularly external migrants. Risk environment factors of low-income status, debt, homelessness, and limited access to medical care were associated with unprotected sex among external migrants.
Conclusion
Study findings underscore the role mobility and risk environments play in shaping HIV/STI risks. They highlight the need to consider mobility in the context of migration status and other risk environment factors in developing effective prevention strategies for this population

Association of Violence Against Female Sex Workers Who Use Drugs With Nonfatal Drug Overdose in Kazakhstan
Importance: Female sex workers (FSWs) who use drugs face increased risk of intimate partner violence (IPV) and nonpartner violence (NPV). The association between violence and drug overdose is unknown.
Objective: To examine the association between IPV, NPV, and nonfatal drug overdose among FSWs who use drugs in Kazakhstan.
Design, Setting, and Participants: This cross-sectional study included 400 adult FSWs in Kazakhstan who reported illicit drug use in the past year, exchanged sex for money or drugs, and reported having unprotected sex in the past 90 days. Baseline data were collected from February 2015 to May 2017 from Project Nova, an HIV prevention study among FSWs who use drugs in Kazakhstan. Data analysis was conducted from April 2019 to March 2020.
Exposures: Lifetime and recent (past 90 day) experiences of physical, sexual, and psychological IPV and NPV using the Revised Conflict Tactics Scale. Subtypes of violence were identified using exploratory factor analysis.
Main Outcomes and Measures: Lifetime and recent incidence of nonfatal overdose; sociodemographic characteristics as well as lifetime and recent sex work and drug use behaviors were also collected.
Results: The 400 participants had a mean (SD) age of 34.1 (8.4) years. Most experienced food insecurity (358 [89.5%]) and homelessness (232 [58.0%]) in the past 90 days; one-third (130 [32.5%]) reported a history of incarceration. Most (359 [89.7%]) experienced some form of violence; 150 (37.5%) reported a lifetime nonfatal overdose, of whom 27 (18.0%) reported nonfatal overdose in the past 90 days. Lifetime severe physical violence (adjusted odds ratio [aOR], 1.27; 95% CI, 1.02-1.59; P = .03), engagement in sex work for more than 10 years (aOR, 2.54; 95% CI, 1.50-4.28; P < .001), and a history of incarceration (aOR, 4.34; 95% CI, 2.58-7.32; P < .001) were associated with greater odds of nonfatal overdose. Engaging in sex work for more than 10 years (aOR, 3.97; 95% CI, 1.36-11.61; P = .01) and a history of incarceration (aOR, 3.63; 95% CI, 1.39-9.48; P = .008) were associated with greater odds of recent nonfatal overdose.
Conclusions and Relevance: In this study, violence against FSWs who use drugs in Kazakhstan was associated with increased odds of nonfatal overdose. Harm reduction programs for women should consider including services to address gender-based violence and the needs of women after incarceration
