BMC Med 2024; 22:18. [PMID: 38185665 PMCID: PMC10773040 DOI: 10.1186/s12916-023-03203-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 11/29/2023] [Indexed: 01/09/2024] Open
Abstract
BACKGROUND Methadone maintenance treatment (MMT) has been implemented in China for nearly two decades, with a significant decrease in the number of participants in recent years. However, there is a lack of comprehensive research focusing on the long-term effectiveness in the context of this decline, especially from the perspectives of MMT participants themselves. This study aims to address this gap by examining the benefits and challenges experienced by long-term MMT participants in China, to uncover potential causes of the decrease in participant numbers and to improve the effectiveness of the program. METHODS We conducted semi-structured interviews with 21 long-term MMT participants (treatment duration ≥ 5 years) recruited through purposive sampling from 6 MMT clinics in the Guangdong Province, China, between December 2021 and August 2022. Thematic analysis was employed to analyze the transcribed interviews. Two analysts independently coded the data, and a third researcher double-coded 20% of transcripts to ensure intercoder reliability. RESULTS Overall, participants corroborated the notable decline in MMT participants during their long-term MMT, citing death, arrest, and self-perceived abstinence from heroin, as their perceived driving factors. They reported positive changes in their health, family relationships, and social functioning. However, they identified economic hardship as their greatest challenge associated with MMT, further exacerbated by other barriers including the conflict of clinic opening hours and working schedules, discrimination from employers, and COVID-19-related restrictions. Additionally, participants identified issues with dose adjustment and emergency treatment continuation. CONCLUSIONS This study outlines the overall improvement in the quality of life of long-term MMT participants. However, it highlights the need for official guidelines for dose adjustment and emergency treatment continuation as well as the provision of health education, job referrals, and flexibility of clinic opening times to facilitate the return to society receiving participants. Establishing a follow-up mechanism for those receiving MMT is also recommended to prevent relapses to heroin and other illicit substances.

Abstract
To estimate the risk of human immunodeficiency virus (HIV) infection through sexual transmission in China from 2013 to 2017 accurately, we divide the total population into three groups, namely, men who have sex with men (MSM) group; non-marital and commercial sex group: female sex workers (FSW) and their clients (FSWC); non-marital and non-commercial sex group: general women (GW) and general men (GM). First, the risks of HIV infection among men who have contacts with infected men or infected women decrease annually. Second, the number of contacts between susceptible FSWC and infected FSW per unit time is greater than that between susceptible MSM and infected MSM, and also greater than that between susceptible FSW and infected FSWC, which suggests that the intervention for commercial sex of heterosexual men should be strengthened. Third, the effective reproduction numbers of the MSM group and non-commercial sex group decrease annually, while the effective reproduction number of the commercial sex group decreases first, then increases, because the risk of women being infected by men decreases first, then increases. Additionally, the effective reproduction number of the commercial sex group exceeds that of the MSM group after 2015, which indicates that commercial sex contributes more and more to the HIV/AIDS epidemic.

Houselessness and syringe service program utilization among people who inject drugs in eight rural areas across the USA: a cross-sectional analysis. Harm Reduct J 2023; 20:157. [PMID: 37880724 PMCID: PMC10601138 DOI: 10.1186/s12954-023-00892-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 10/16/2023] [Indexed: 10/27/2023] Open
Abstract
BACKGROUND Research conducted in urban areas has highlighted the impact of housing instability on people who inject drugs (PWID), revealing that it exacerbates vulnerability to drug-related harms and impedes syringe service program (SSP) use. However, few studies have explored the effects of houselessness on SSP use among rural PWID. This study examines the relationship between houselessness and SSP utilization among PWID in eight rural areas across 10 states. METHODS PWID were recruited using respondent-driven sampling for a cross-sectional survey that queried self-reported drug use and SSP utilization in the prior 30 days, houselessness in the prior 6 months and sociodemographic characteristics. Using binomial logistic regression, we examined the relationship between experiencing houselessness and any SSP use. To assess the relationship between houselessness and the frequency of SSP use, we conducted multinomial logistic regression analyses among participants reporting any past 30-day SSP use. RESULTS Among 2394 rural PWID, 56.5% had experienced houselessness in the prior 6 months, and 43.5% reported past 30-day SSP use. PWID who had experienced houselessness were more likely to report using an SSP compared to their housed counterparts (adjusted odds ratio [aOR] = 1.24 [95% confidence intervals [CI] 1.01, 1.52]). Among those who had used an SSP at least once (n = 972), those who experienced houselessness were just as likely to report SSP use two (aOR = 0.90 [95% CI 0.60, 1.36]) and three times (aOR = 1.18 [95% CI 0.77, 1.98]) compared to once. However, they were less likely to visit an SSP four or more times compared to once in the prior 30 days (aOR = 0.59 [95% CI 0.40, 0.85]). CONCLUSION This study provides evidence that rural PWID who experience houselessness utilize SSPs at similar or higher rates as their housed counterparts. However, housing instability may pose barriers to more frequent SSP use. These findings are significant as people who experience houselessness are at increased risk for drug-related harms and encounter additional challenges when attempting to access SSPs.

Exploring factors jointly associated with recurrent relapse and dropout of methadone maintenance treatment clients in Guangdong, China: A retrospective cohort study. Drug Alcohol Depend 2023; 243:109739. [PMID: 36535097 DOI: 10.1016/j.drugalcdep.2022.109739] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 11/14/2022] [Accepted: 11/24/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND Clients receiving methadone maintenance treatment (MMT) may experience multiple relapses, which may lead to dropout. However, previous studies mostly only explored the influencing factors of relapse or dropout separately. In this study, we investigated the influencing factors jointly associated with both recurrent relapse and dropout. METHODS This study was conducted in 16 MMT clinics in Guangdong, China. Data on the clients' demographic characteristics; drug-related behavior; HIV, HCV, and urine morphine test results; and daily methadone doses were collected. The outcomes were time to recurrent relapse and time to dropout. A joint frailty model was used to explore factors jointly associated with recurrent relapse and dropout. The hazard ratios (HRs) of the covariates in the multivariable model were adjusted, with HR > 1 indicating a faster time to recurrent relapse and dropout. RESULTS Among 1539 clients, 39.5% had ≥ 2 relapse events, and 90.8% of the clients dropped out. A high attendance rate was protective for recurrent relapse (HR50-80%=0.63, 95% CI: 0.51, 0.79; HR>80%=0.35, 95% CI: 0.28, 0.44) and dropout (HR50-80%=0.56, 95% CI: 0.47, 0.68; HR>80%=0.27, 95% CI: 0.23, 0.33). Being married (HR=0.80, 95% CI: 0.67, 0.96), having a fair relationship with family (HR=0.79, 95% CI: 0.67, 0.93) and drug injection (HR=0.80, 95% CI: 0.67, 0.96) were also protective for recurrent relapse. Female (HR=0.64, 95% CI: 0.50, 0.82) and a high methadone dose (≥60 ml/day; HR=0.79, 95% CI: 0.65, 0.96) were protective for dropout, and a longer traveling time to the clinic (>60 min; HR=1.59, 95% CI: 1.20, 2.10) was associated with an increased risk of dropout. CONCLUSIONS It is common for clients to experience recurrent relapse and dropout. The findings suggest that MMT clinics should provide holistic interventions and appropriate methadone doses for clients to improve treatment compliance.

Feasibility of a Brief Intervention to Decrease Harmful Alcohol Use Among Methadone Maintenance Treatment Clients in Shanghai: A Randomized Controlled Trial. J Addict Med 2022:01271255-990000000-00109.

Abstract
OBJECTIVES In this study, we aimed to examine the prevalence of alcohol consumption among methadone maintenance treatment (MMT) clients in Shanghai and to determine whether a brief intervention (BI) affects drinking among them. METHODS A total of 837 clients from 14 local MMT clinics were invited to complete the Alcohol Use Disorders Identification Test (AUDIT). One hundred one were included in the study and randomly assigned to the BI group or the control group. Clients in the BI group received a BI and general health education, whereas clients in the control group received the general health education only. Baseline and postintervention assessments were conducted by using the AUDIT, the Drinking Attitude Questionnaire, the Depression Module of the Patient Health Questionnaire, the Generalized Anxiety Disorder Scale, and the General Well-Being Schedule. RESULTS Two hundred fifty-nine (30.9%) reported drinking during the last year, and 103 (12.3%) met the criteria for harmful use. At the 3-month follow-up, the AUDIT scores of the 2 groups were significantly decreased, and the time effect was statistically significant ( F = 6.224, P = 0.018), but there was no group difference in AUDIT scores ( F = 1.953, P = 0.172). Both groups had a main time effect of time on the improvement of depression ( F = 8.044, P = 0.008), anxiety ( F = 9.650, P = 0.004), and general well-being ( F = 5.056, P = 0.033). However, there was no statistical difference between the 2 groups ( P > 0.05), and no statistical difference in the time ( F = 1.738, P = 0.198) and group ( F = 0.658, P = 0.424) effect of drinking attitude. CONCLUSIONS Alcohol consumption is common among MMT clients in China. Brief intervention, in its current form, could not effectively help them reduce their alcohol consumption.

Abstract
BACKGROUND The HIV epidemic in key populations such as men who have sex with men (MSM) is a public health issue of worldwide concern. China has seen an increase in newly diagnosed HIV infections through male-male sexual contact in the past decade. In a long-term cohort, how the complex behaviour pattern of MSM changed and the association with the HIV risk are unclear at present. METHODS This study was conducted from October 2011 to December 2019 in Tianjin. MSM were recruited by snowball sampling through online and offline ways. Demographic and sexual behavioural data were collected for analysis. Three indicators (condom use in last anal sex, frequency of condom use during anal sex and the number of sexual partners) were used to define the behaviour change. Participants with zero, one, and two or three risk indicators were categorised into behaviour types of 'protective', 'moderate', and 'fragile', respectively. Change in behaviour type between baseline and each visit was considered. Time-varying Cox models were performed to evaluate HIV infection risk. RESULTS Of 2029 MSM included in the study, 127 were new HIV diagnoses. The overall incidence rate was 3.36 per 100 person-years. The percentage of 'protective' and 'moderate' behaviour types had a conspicuous growth trend as the follow-up. Furthermore, the HIV incidence rate in each visit among different behaviour transition types showed a general downward trend as the number of total follow-up times increased. Individuals who remained in 'fragile' (adjusted HR (aHR): 25.86, 95% CI: 6.92 to 96.57) or changed from 'protective' to 'moderate' (aHR: 4.79, 95% CI: 1.18 to 19.47), 'protective' to 'fragile' (aHR: 23.03, 95% CI: 6.02 to 88.13), and 'moderate' to 'fragile' (aHR: 25.48, 95% CI: 6.79 to 95.40) between baseline and the last follow-up had a higher HIV risk. Gained risk indicators were associated with the increase of HIV risk (gained one indicator, aHR: 2.67, 95% CI: 1.68 to 4.24; gained two or three indicators, aHR: 4.99, 95% CI: 3.00 to 8.31) while losing just one risk indicator could halve the risk (aHR: 0.43, 95% CI: 0.21 to 0.90). CONCLUSIONS Among MSM in Tianjin, it is necessary to get timely behaviour change for those with high-incidence behaviour patterns while sustaining for those with low-incidence patterns. TRIAL REGISTRATION NUMBER Chinese Clinical Trials Registry (ChiCTR2000039500).

Abstract
Harm is a concept that permeates behavioral and public health discourses on addiction. Examining addiction recovery services in settings beyond the OECD led me to the question: What does harm mean in an un-urban, un-Western, and un-democratic space? While some emphasize the human rights potential of reducing harm, others speak to the violence of cure. My ethnographic research in a Therapeutic Community (TC) for drug treatment in Southwest China pushed me to consider how the potential for reducing the harms of illegal substance use balance with the complex psychological demands of cure. The alliance linking Sunlight Therapeutic Community with the provincial drug abuse institute and a foreign NGO was fragile. At the TC, they had difficulty weaving the Western psychological construct of the singular self through the Chinese scaffolding of institutional and cultural practices around the group. In thinking with the concepts of harm and reducing harm, I move across time and space to consider how current tensions link to and reflect: 1) the historical harms of opium imperialism; 2) reducing harm in translation; and, 3) reducing harm in the recent psycho-boom.

Abstract
BACKGROUND Hospital is an important place for HIV/AIDS screening, and a general hospital is composed of multiple departments. Different departments have different levels of understanding of HIV/AIDS, especially the sexually transmitted diseases (STD) department is the main place for HIV/AIDS screening. OBJECTIVE The study aims to validate the common knowledge that the STD department is an important place for HIV/AIDS screening by comparing the epidemiological characteristics of HIV/AIDS patients in the STD department and other departments in Tongji Hospital, which can provide a theoretical basis for the precise and differentiated control of HIV/AIDS. METHODS A total of 283,525 HIV screening cases were analyzed from January 1st 2006 to December 31st 2018 in the STD department and other departments. The epidemiological data of 226 HIV/AIDS cases were retrospectively analyzed. RESULTS Firstly, the incidence of HIV/AIDS in the population served by Tongji Hospital was higher than that in Shanghai and China. Secondly, the positive rate of HIV screening test in the STD department was ten times higher than that of other departments. Thirdly, the social-demographic characteristics of HIV/AIDS patients in the STD department were different from those in other departments. Fourthly, there were differences in age, education, marital status and number of sex partners between men who have sex with men (MSM) and men who have sex with women (MSW). Fifthly, there was no difference except age in social-demographic characteristics of MSM between the STD department and other departments. Sixthly, compared with other departments, the majority of HIV/AIDS patients in the STD department were MSM. Seventhly, syphilis and HIV co-infection were not statistically significant in HIV/AIDS patients between the STD department and other departments. CONCLUSION Firstly, the significantly higher positive rate of an HIV screening test in the STD department emphasizes its importance as a place for screening HIV/AIDS patients. Secondly, HIV/AIDS patients diagnosed in the general hospital were mainly transmitted by sexual contact, and MSM accounted for the most part of these patients. More attention should be paid to screen outpatients, especially in the STD department and young men.

Abstract
OBJECTIVE Service providers' job satisfaction is critical to the stability of the work force and thereby the effectiveness of methadone maintenance treatment (MMT) programs. This study aimed to explore MMT clinic service providers' job satisfaction and associated factors in Jiangsu, China. METHODS This secondary study used baseline data of a randomized interventional trial implemented in Jiangsu, China. A survey was conducted among 76 MMT service providers using the computer-assisted self-interview (CASI) method. Job satisfaction responses were assessed via a 30-item scale, with a higher score indicating a higher level of job satisfaction. Perceived institutional support and perceived stigma due to working with drug users were measured using a 9-item scale. Correlation and multiple linear regression analyses were performed to identify factors associated with job satisfaction. RESULTS Correlation analyses found a significant association between job satisfaction and having professional experience in the prevention and control of HIV, other sexually transmitted infections, or other infectious diseases (P = 0.046). Multiple regression analyses revealed that working at MMT clinics affiliated with Center for Disease Control and Prevention sites was associated with a lower level of job satisfaction (P = 0.014), and perception of greater institutional support (P = 0.001) was associated with a higher level of job satisfaction. CONCLUSION Job satisfaction among MMT clinic service providers was moderate in our study. Our findings suggest that institutional support for providers should be improved, and that acquisition of additional expertise should be encouraged.

A national survey of HIV knowledge, sexual practices and attitude towards homosexuality for HIV elimination among young people in China. Sex Health 2021; 18:64-76. [PMID: 33632383 DOI: 10.1071/sh20122] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Accepted: 09/04/2020] [Indexed: 11/23/2022]
Abstract
Background Elimination of HIV is a public health priority in China, but there has been reports of an upsurge in HIV among young people. A nationwide cross-sectional survey was conducted to assess the awareness of HIV knowledge, attitudes towards homosexuality and practice of sexual behaviours among Chinese aged 15-24 years. METHODS The face-to-face survey was conducted from June to August 2017, collecting data on sociodemographic characteristics, HIV-related knowledge, attitudes towards homosexuality and practice of sexual behaviours among Chinese senior high school and university students. A generalised linear model (GLM) was used to assess the different levels of HIV knowledge between groups, and identify the key contributors to HIV knowledge scores. RESULTS The survey was completed by 73.6% (1355/1840) of the students approached. The overall level of HIV-related knowledge was low (58.9%, 10.6/18); 48.0% (650/1355) supported same-sex marriage; and 6.9% (93/1355) self-identified as homosexual or bisexual. The major factors associated with higher scores [mean ± standard deviation (s.d.)] in HIV knowledge among students included: having received school-based HIV education (11.47 ± 3.51 vs 9.02 ± 4.14, P < 0.05); support for same-sex marriage (11.69 ± 3.33 vs 9.49 ± 4.29, P < 0.05) and older age (11.61 ± 2.78 vs 9.87 ± 4.17, P < 0.05). Compared with females, males were significantly more likely (all P < 0.05) to report masturbation (60.7% vs 7.6%), pornography experiences (77.4% vs 35.3%), sexual encounters (24.6% vs 12.3%), casual sex (37.0% vs 18.1%) and sex under the influence of alcohol (29.5% vs 12.8%). CONCLUSIONS There is is still much room for improvement in terms of HIV/AIDS prevention and health education for Chinese young people, and more comprehensive and diverse models of education for HIV prevention are urgently needed.

Abstract
BACKGROUND In China, body packing as a means of transporting drugs was firstly found in Yunnan province in an area that shares a border with the Golden Triangle in late 1970s. Since then, drug trafficking cases that utilize body packing as the primary mode of transportation have increased substantially. Due to a scarcity of data, however, the scope and nature of such criminal activity is not thoroughly understood. This study provides a new approach to the analysis of body packing by digitizing and analyzing court sentencing documents in China from 2006-2016. METHODOLOGY This study implements network analysis and descriptive statistics to identify the structures of drug trafficking routes involving body packing in China and aims to provide a comprehensive examination of body packing activity, including the pattern of geographic routes and the characteristics of captured body packers. A generalized inflated negative binomial model is also used to investigate the effects of legal and extra-legal factors on the length of sentence for captured body packers. RESULTS We identified three types of trafficking routes involving body packing: intra-provincial, inter-provincial, and international. Our results showed that heroin and methamphetamine are the two primary drugs trafficked by captured body packers. Network analysis revealed that among body packing routes, there are three major hubs that serve as the primary origin for the trafficking -Yunnan, Sichuan, and Myanmar- and three potential authorities- Guangdong, Xinjiang, and Sichuan-which serve as the common destinations of the drug routes. Consistent with previous studies, our research also demonstrated that heavier punishments are given in cases that involve a larger quantity of drugs and repeat offenders. Offenders who fall into special groups, such as pregnant/lactating women, the disabled, or minors, receive more lenient sentences. In addition, our analysis further revealed that the logic behind longer sentences for those offenders who confessed as opposed to those who did not, is possibly due to the concentration of imprisonment values at fifteen years, as many of the confessed body packers are sentenced to the maximum fixed term of imprisonment. CONCLUSION By narrowing the gap in knowledge on the topic of body packing, our analysis provides evidence-based strategies for fighting against body packing, specifically by identifying geographical patterns and the profiles of captured body packers.

No Increase in HIV Drug Resistance Mutations among Injecting Drug Users on Methadone Maintenance Therapy: A Prospective Cohort Study. Curr HIV Res 2020; 18:362-372. [PMID: 32652910 DOI: 10.2174/1570162x18666200712173630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2020] [Revised: 06/21/2020] [Accepted: 06/24/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Whether HIV-positive injecting drug users (IDUs) are at higher risk of developing drug resistance mutations (DRMs) after methadone maintenance therapy (MMT) than any other HIV-positive population is unclear. OBJECTIVE To compare the incidence of new DRMs in two population groups: antiretroviraltreatment (ART) HIV-positive IDUs and non-drug users. METHODS A prospective cohort of ART HIV-positive patients including IDUs who received MMT (MMT group) and non-drug users (N-MMT group) was established from April 2016 to December 2017 in Guangxi, China. RESULTS Of the 80 participants, 43 were in the MMT group and 37 were in the N-MMT group. Compared with the N-MMT group, the HRs of PIs, NRTIs and NNRTIs for new DRMs in the MMT group was 1.55 (95%CI: 0.28-8.64; P = 0.616), 1.51 (95%CI: 0.44-5.20; P = 0.512) and 0.45 (95%CI: 0.15-1.35; P = 0.155), respectively. There was no dose-response relationship between MMT and new DRMs for PIs, NRTIs and NNRTIs (P > 0.05). The new DRM incidence for NRTIs (138.23 per 104 person-months) was higher than for PIs (94.16 per 104 person-months) and NNRTIs (95.41per 104 person-months) in the MMT group, while the new DRM incidence for NNRTIs (208.24 per 104 person-months) was higher than for PIs (44.13 per 104 person-months) and NRTIs (91.78 per 104 person-months) in the N-MMT group. CONCLUSION Among ART HIV-positive patients, there is no significant difference in the incidence of new DRMs between IDUs receiving MMT and non-drug users. MMT has little impact on the development of DRMs among IDUs.

Abstract
Background Two phase I studies assessed the pharmacokinetics of buprenorphine, its metabolite norbuprenorphine, and naloxone following administration of buprenorphine/naloxone sublingual tablets in Chinese participants. Methods In the first phase I, open-label, single ascending-dose (SAD) study, 82 opioid-naïve volunteers received a single buprenorphine/naloxone dose ranging from 2 mg/0.5 mg to 24 mg/6 mg while under naltrexone block. In a second phase I, open-label, multiple ascending-dose (MAD) study, 27 patients with opioid dependence in withdrawal received buprenorphine/naloxone doses of either 16 mg/4 mg or 24 mg/6 mg for 9 consecutive days. Serial blood samples were collected after a single dose (SAD study) and at steady-state (MAD study). Pharmacokinetic parameters were calculated using non-compartmental analysis. Safety assessments included adverse events monitoring and laboratory tests. Results The pharmacokinetic profiles of buprenorphine and naloxone were consistent between single- and multiple-dose studies. Peak plasma concentrations (Cmax) were reached early for buprenorphine (0.75–1.0 h) and naloxone (0.5 h), supporting rapid absorption. In the SAD study, increases in plasma exposures to buprenorphine and naloxone were less than dose proportional, in line with previous observations in Western populations. Buprenorphine-to-naloxone ratios for Cmax and area under the curve (AUC) were constant over the dose range investigated and also consistent with Western populations data. Steady state was reached within 7 days of daily dosing, with slight accumulation over repeated doses. No serious adverse events were observed. Conclusions The present data suggest that buprenorphine/naloxone pharmacokinetic profiles in Chinese participants are consistent, overall, with those in Western populations, supporting no differences in dosing. Clinical Trial Registration The protocols were registered on the official website of the China Food and Drug Administration (CFDA): http://www.chinadrugtrials.org.cn/; Registration numbers CTR20132963 (RB-CN-10-0012), CTR20140153 (RB-CN-10-0015).

Abstract
PURPOSE OF REVIEW This study aims to review the history of the human immunodeficiency virus (HIV) infection epidemic in China. RECENT FINDINGS The HIV infection epidemic in China has evolved significantly over the past 35 years, from initially exclusively within people who inject drugs (PWID), to outbreaks due to plasma collection contamination in the mid-1990s, to now almost exclusive transmission via sexual contact. The number of newly-diagnosed cases and the number HIV-related deaths have increased each year since 2004, coinciding with a massive scale-up of both HIV testing and antiretroviral therapy initiation. The proportion of cases diagnosed later in their disease progression has remained constant. The initial outbreaks of HIV across China were identified quickly and the overall trends have been monitored. While the HIV epidemic among PWID has been well managed, the growing HIV epidemic via sexual contact has grown more complex and even more difficult to control.

Abstract
China is experiencing rapid cultural change and new forms of sociability that are accompanied by social problems and novel humanitarian interventions that have been formulated to address those problems. The pressure related to the rapid transformation of the countryside into mid-level cities has led to recreational drug-use as a means of escape. These illegal drugs have greased the wheels of what I call an affective biopolitics that has influenced Chinese citizens. Carlos Rojas argues that development in China results from the effects of discrete protocols, or practices that stem from tensions between capital and labor, governmentality and biopolitics, and nationalism and globalization. To tease out the particulars of Rojas' protocols and practices, in this article, I first review two historical periods: 1) the rise and fall of opium consumption in the early 19th century, and 2) the 21st-century psychology boom. I use these two literature reviews to set the stage to discuss my ethnographic study of Sunlight, China's first residential therapeutic community for drug users in Yunnan Province. Sunlight's residents and founders provide a unique window into local everyday drug use at a particular time in China's economic boom, from 2007 through 2015. We know much about China's opium century but very little about the contemporary context, new consumers who partake in pleasure-consuming drugs, or the reformers who address these 21st-century public health issues.

Abstract
Methadone maintenance therapy (MMT) is effective in treatment of opiate dependents. However, there is a gap between the coverage of standard MMT clinics and the need of opiate dependents. Establishment of extension clinics of methadone maintenance therapy (EMMT) will increase the coverage and improve MMT accessibility. We implemented a prospective cohort study to understand the effects of establishment of community-based EMMT clinics comparing with MMT clinics in Yunnan Province.A total of 462 opiate-dependent clients were interviewed from the community-based EMMT clinics and standard MMT clinics located in 5 counties of Mangshi, Ruili, Longchuan, Yingjiang, and Lianghe in Yunnan Province. The information on the demographic characteristics, drug risk behaviors, quality of life (QOL), and urine testing results for morphine of the clients was collected and compared between the EMMT and MMT clinics. A survival analysis method was utilized to know the retention situation of the newly enrolled clients with Kaplan-Meier method during 9 months treatment.Among the EMMT clients, 96.9% were male; 31.4% were Han; 61.4% were married; 39.0% had primary school education; 95.5% lived with their family or relatives; 96.9% who arrived the clinic less than 15 min; 52.9% had used drugs for more than 10 years; and 16.7% injected drug. After 9 months therapy, there was no difference in the changes of life quality such as physical and psychological features, social relationships, environmental function, and total QOL and well-being between those of EMMT and MMT clinics. The positive detection rate of urine-morphine testing among newly enrolled clients of EMMT clinics decreased as the period of treatment lengthened. The average time of retention for newly enrolled EMMT clients who are still receiving the treatment was 175 days. And the average time from initiations to drop-out of treatment for newly enrolled EMMT clients was 122 days. The 9-month retention rates of the clients were 52.1% and 60.9% at EMMT and MMT clinics, respectively.The effect on EMMT retention was the same as that of MMT. Establishment of EMMT clinics was an effective strategy to expand the coverage of MMT and increase the retention of opiate dependents in the rural areas of the counties.

Shen L, Assanangkornchai S, Liu W, Cai L, Li F, Tang S, Shen J, McNeil EB, Chongsuvivatwong V. Influence of social network on drug use among clients of methadone maintenance treatment centers in Kunming, China. PLoS One 2018; 13:e0200105. [PMID: 29969481 PMCID: PMC6029801 DOI: 10.1371/journal.pone.0200105] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2018] [Accepted: 06/19/2018] [Indexed: 01/01/2023] Open
Abstract
AIMS To examine drug use behavior of clients attending Methadone Maintenance Treatment (MMT) programs and its relationship with the clients' social network characteristics. DESIGN Cross-sectional study. SETTING Four MMT clinics in Kunming, Yunnan province, China. PARTICIPANTS 324 consecutive MMT clients. MEASUREMENTS A structured, self-completed questionnaire on background characteristics and existing social network. Current drug use was assessed by urine test for opiate metabolites. ANALYSIS The association between client's social network characteristics and their own current drug use behavior is analysed using multiple logistic regression adjusting for socio-demographic characteristics. Adjusted odds ratios (AOR) with 95% confidence intervals (CI) are obtained to give the strength of the associations. FINDINGS MMT clients were more likely to concurrently use heroin while attending MMT if their social network had any of the following characteristics: more than half of the members were older than them (AOR = 1.03, 95% CI = 1.00,1.06), any member had a high level of influence on them (AOR = 6.47, 95% CI = 2.86,14.65) and any member joined them in using drugs (AOR = 1.94, 95% CI = 1.04,3.63). Having a social network member who could provide emotional support (AOR = 0.11, 95% CI = 0.03,0.35), having a spouse and/or child in their social network (AOR = 0.44, 95% CI = 0.24,0.81) and having a social network member with a high level of closeness (AOR = 0.28, 95% CI = 0.09,0.90) were associated with a decreased odds of heroin use. CONCLUSION Social networks who could provide MMT clients with emotional support and a close relationship were significant factors for reducing the risk of concurrent drug use among clients attending MMT clinics in Kunming, China. Behavioral interventions should address the role of family and social network members in providing support to these clients.

Abstract
Background Opioid use is a severe problem in Iran. Despite methadone maintenance treatment (MMT) programs being one of the most important treatment strategies for reducing individual and public harms associated with opioid use, a large proportion of Iranian patients refuse to participate in such treatment programs. Methods The present study aims to explore the beliefs and attitudes toward MMT programs of opioid-dependent patients who were participating or had participated in methadone therapy. In-depth interviews were conducted with 23 opioid users between 27 and 58 years of age from Kurdistan provinces. Results Overall, six themes were discovered to be key barriers relating to methadone treatment, including financial barriers related to methadone treatment, lack of awareness about methadone treatment, negative attitudes regarding using methadone, worries about methadone’s side effects, social stigma ascribed to methadone therapy, and systemic barriers to methadone treatment. Conclusion Our study revealed that the cost of treatment is a major obstacle to attending and continuing at MMT programs and that addicts and their families are not always accurately informed about the duration of MMT programs and the side effects of methadone treatment.

Abstract
BACKGROUND Mobile health (mHealth) technologies have the potential to facilitate self-monitoring and self-management for individuals with substance use disorders (SUD). S-Health is a bilingual smartphone application based on cognitive behavioral principles and is designed to support recovery from drug addiction by trigger recognition so as to allow practice in-the-moment coping to prevent relapse. METHOD For this pilot randomized controlled study, 75 participants were recruited from methadone maintenance treatment clinics and the social worker consortium in Shanghai, China. Participants in the control group (N=25) received text messages from S-Health (e.g., HIV prevention and other educational materials). Participants in the intervention group (N=50) received both text messages and daily surveys on cravings, affects, triggers, responses to triggers, and social contexts. RESULTS At the end of the 1-month study trial, 26.2% of the intervention group and 50% of the control group had positive urine test results (p=0.06). Also, the number of days using drug in the past week was significantly lower among participants in the intervention group (Mean=0.71, SD=1.87) relative to the control group (Mean=2.20, SD=3.06) (p<0.05). The two groups did not differ in slopes (i.e., rates of change in outcomes measured weekly) based on the mixed effects model. Participants in the intervention group also preferred answering questions on the cellphone (46.8%) relative to in-person interviews (36.2%). CONCLUSIONS This pilot demonstrated the feasibility and potential benefits to deliver mobile health intervention among participants with SUD. Further research with larger samples over a longer period of time is needed to test the effectiveness of S-Health as a self-monitoring tool supporting recovery from addiction.

Abstract
Studies utilizing functional magnetic resonance imaging (fMRI) cue-reactivity paradigms have demonstrated that short-term abstinent or current methamphetamine (MA) users have increased brain activity in the ventral striatum, caudate nucleus and medial frontal cortex, when exposed to MA-related visual cues. However, patterns of brain activity following cue-reactivity in subjects with long-term MA abstinence, especially long-term compulsory drug rehabilitation, have not been well studied. To enrich knowledge in this field, functional brain imaging was conducted during a cue-reactivity paradigm task in 28 individuals with MA use disorder following long-term compulsory drug rehabilitation, and 27 healthy control subjects. The results showed that, when compared with controls, individuals with MA use disorder displayed elevated activity in the bilateral medial prefrontal cortex (mPFC) and right lateral posterior cingulate cortex in response to MA-related images. Additionally, the anterior cingulate region of mPFC activation during the MA-related cue-reactivity paradigm was positively correlated with craving alterations and previous frequency of drug use. No significant differences in brain activity in response to pornographic images were found between the two groups. Compared to MA cues, individuals with MA use disorder had increased activation in the occipital lobe when exposed to pornographic cues. In conclusion, the present study indicates that, even after long-term drug rehabilitation, individuals with MA use disorder have unique brain activity when exposed to MA-related cues. Additionally, our results illustrate that the libido brain response might be restored, and that sexual demand might be more robust than drug demand, in individuals with MA use disorder following long-term drug rehabilitation.

Abstract
This study examined the re-entry characteristics and related predictors among HIV-infected methadone maintenance treatment (MMT) clients in Guangdong, China. Data on HIV-infected MMT clients was obtained from the clinic MMT registration system in Guangdong. Of the 653 participants, only 9.0% remained in the MMT program until the end of the study. For the drop-outs, 70.0% returned to MMT at least once by the end of the study. Re-entry was independently associated with marital status (ORnever married = 2.24, 95% CI: 1.02-4.93; ORmarried currently = 2.34, 95% CI: 1.05-5.22), being unemployed (OR = 1.92, 95% CI: 1.12-3.27), lower positive percentages of urine tests (OR<40% = 4.08, 95% CI: 2.21-7.54; OR40%-80% = 2.52, 95% CI: 1.39-4.56), higher maintenance doses (OR = 3.78, 95% CI: 2.21-7.54)and poorer MMT attendance percentages (OR<20% = 282.02, 95% CI: 62.75-1268.11; OR20-49% = 20.75, 95% CI: 10.52-40.93; OR50-79% = 6.07, 95% CI: 3.44-10.73). A higher re-entry frequency was independently associated with lower education level (ORjunior high school = 0.49, 95% CI: 0.26-0.93), average drug use times less than twice (OR = 0.64, 95% CI: 0.41-1.00), lower positive percentages of urine tests (OR = 0.39, 95% CI: 0.22-0.70) and poorer percentages of MMT attendance (OR<20% = 7.24, 95% CI: 2.99-17.55; OR20-49% = 14.30, 95% CI: 5.94-34.42; OR50-79% = 6.15, 95% CI: 2.55-14.85). Re-entry and repeated re-entry were prevalent among HIV-infected MMT clients in Guangdong, underscoring the urgent needs of tailored interventions and health education programs for this population.

Abstract
Background Since 2003, a harm reduction program for injecting drug users has been rolled out countrywide in China. It entails services for condom promotion, a needle and syringe program (NSP), and methadone maintenance treatment (MMT). However, it remains unknown if and to what extent the coverage of these services at city level is related to a reduced risk of HIV infection among drug users. Methods We wished to quantify the extent to which city-level characteristics (such as NSP and MMT service coverage) and individual-level determinants (e.g., self-reported exposure to NSP and MMT services, knowledge, motivation, and skills) were associated with the risk of HIV infection among drug users. In 2006, we conducted an integrated serological and behavioral survey among drug users in five cities of Yunnan Province, China (N = 685), constructing a multilevel logistic regression model with drug users clustered within these cities. Results Drug users who reported having received NSP or MMT services were about 50% less likely to be infected with HIV than those who reported not having received them (OR 0.45, 95% CI, 0.26–0.83 for NSP and 0.48, 95% CI, 0.31–0.73 for MMT). Despite a between-city variation of HIV infection risk (ICC 0.24, 95% CI 0.08–0.54), none of the city-level factors could explain this difference. Individual-level determinants such as perceived risk of infection and use of condoms were not associated with HIV infection. Conclusions Although people who had used NSP or MMT services were less likely to be HIV infected, this study found no relationship between city-level coverage of HIV prevention programs and variations in HIV infection between cities. This may have been due to the low number of cities in the analysis. Future research should include the analysis of data from a larger number of cities, which are collected widely in China through integrated behavioral and serological surveys.

Abstract
OBJECTIVES To investigate factors associated with illicit opioid use among methadone maintenance treatment (MMT) population. METHODS Participants were recruited from Beijing (2 clinics), Shanghai (2 clinics), Guangdong (2 clinics), Chongqing (2 clinics) and Gansu (1 clinic) provinces. Information about heroin use and MMT was obtained from a self-reported questionnaire, illicit opioid use was obtained from monthly medical records. Binary logistic regression was used to investigate factors associated with illicit opioid use. RESULTS Five hundred ninety-eight eligible MMT participants were used for data analysis. Variables such as age, gender, route of heroin use and daily MMT dosages were associated with illicit opioid use. Compared with MMT participants aged <40 years, participants aged 40-44 years (P = 0.027, OR = 0.57, 95 % CI 0.35-0.94), 45-49 years (P < 0.001, OR = 0.41, 95 % CI 0.24-0.67) and ≥50 years (P = 0.008, OR = 0.52, 95 % CI 0.33-0.85) were more likely not to have illicit opioid use. Compared with male participants, females were more likely to have illicit opioid use (P = 0.044, OR = 1.53, 95 % CI 1.01-2.32). Compared with inhalation heroin abusers, abusers with route of inhalation + injection heroin use were more likely to have illicit opioid use (P = 0.009, OR = 2.00, 95 % CI 1.19-3.36). Compared with daily MMT dosages <60 mg participants, participants with daily MMT dosages >80 mg were more likely to have illicit opioid use (P = 0.003, OR = 2.37, 95 % CI 1.35-4.15). CONCLUSIONS Age, gender, route of heroin use and daily MMT dosages were associated with illicit opioid use. A tailored intervention is needed for a promotion of MMT.

Abstract
Background Current prevalence and genotype distribution of hepatitis C virus (HCV) infection remain unknown in Ningxia, northwest China. Methods From June to December 2013, 13,022 individuals were screened in Ningxia HIV/AIDS Sentinel Surveillance System, with their demographic features collected and serum samples tested for HCV antibody. Sero-positive drug users were further subjected to sequencing of NS5B and Core regions of HCV. Results The anti-HCV prevalence was 0.34 % among individuals without history of drug use, while it was 15.80 % among drug users. Of 79 NS5B sequences amplified from drug users, 64 (81.0 %) were male and 51 (64.0 %) were injection drug users (IDUs). Subtype 3a (40.5 %) and 1b (25.3 %) were the most predominant subtypes, followed in frequency by 3b (10.1 %) and 2a (7.6 %). Subtype distribution has no significant difference between injection and non-injection drug users. Based on phylogeographic analysis, HCV strains in Ningxia IDUs were mainly originated from two sites, Yunnan province (in southwest China bordering Myanmar, also known as Burma) and Xinjiang Autonomous Region (in northwest China on the border of Central Asia), which are the two major drug trafficking originates in China. Previously reported drug-resistance mutations were also scanned in this treatment-naïve population. Amino acid substitutions (C316N) associated with direct anti-viral agents (DAA) resistance were identified in the NS5B region in seven samples. Conclusion This study is the first to reveal the existence of multiple genotypes of HCV in Ningxia, an inland province in northwest China, suggesting the rapid spreading of the virus.

Abstract
OBJECTIVE We sought to explore the experiences of drug users in China who were recently diagnosed with HIV infection while engaged in methadone maintenance treatment (MMT) and to better understand their perceptions of MMT, HIV risk, and HIV prevention. METHODS We recruited clients of MMT clinics in Chongqing and Kunming who had a baseline HIV-negative test result upon entry to MMT and had been diagnosed with HIV within the past 12 months. We conducted semi-structured qualitative interviews and thematic data analysis to identify situations and factors that increased HIV risk. RESULTS Among the 27 participants who were interviewed, 15 believed their infection was due to injection drug use, 7 attributed their infection to sexual contact, and 5 were unsure as to how they became infected. High risk behaviors were common; 18 participants continued to use drugs during treatment, and 10 engaged in unprotected sex. Common themes were the difficulty of drug abstinence despite receiving MMT, social pressure to continue using drugs, and low knowledge of effective HIV prevention measures. CONCLUSION While MMT is effective in reducing drug usage and needle sharing, many clients remain at risk of HIV infection due to continued injection drug use and unprotected sex. Clients may benefit from additional counseling on HIV prevention methods as well as structural interventions to increase the availability of clean injection equipment.

Abstract
Smartphone-based interventions are increasingly used to support self-monitoring, self-management, and treatment and medication compliance in order to improve overall functioning and well-being. In attempting to develop a smartphone application (S-Health) that assists heroin-dependent patients in recovery, a series of focus groups (72 patients, 22 providers) were conducted in China, Taiwan, and the USA to obtain their perspectives on its acceptance and potential adoption. Data were analyzed according to the Diffusion of Innovation (DOI) theory of characteristics important to the adoption of innovation. Important to Relative Advantage, USA participants cited S-Health's potential ability to overcome logistical barriers, while those in China and Taiwan valued its potential to supplement currently limited services. In terms of Compatibility, participants across sites reported recovery needs and goals that such an application could be helpful in supporting; however, its utility during strong craving was questioned in China and Taiwan. Important factors relevant to Complexity included concerns about smartphone access and familiarity, individualization of content, and particularly in China and Taiwan, participants wanted assurance of privacy and security. The study results suggest a general acceptance, but also indicate cultural variations in access to therapeutic and other social support systems, legal repercussions of substance use, societal perceptions of addiction, and the role of family and other social support in recovery. Taking these factors into consideration is likely to increase diffusion as well as effectiveness of these smartphone-based interventions.

Barriers to community-based drug dependence treatment: implications for police roles, collaborations and performance indicators. J Int AIDS Soc 2016; 19:20879. [PMID: 27435714 PMCID: PMC4951535 DOI: 10.7448/ias.19.4.20879] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2015] [Revised: 04/26/2016] [Accepted: 05/02/2016] [Indexed: 12/12/2022] Open
Abstract
Introduction Worldwide, people who use drugs (PWUD) are among the populations at highest risk for HIV infection. In China, PWUD are primarily sentenced to compulsory detainment centres, in which access to healthcare, including HIV treatment and prevention services, is limited or non-existent. In 2008, China's 2008 Anti-Drug Law encouraged the development and use of community-based drug dependence rehabilitation, yet there is limited evidence evaluating the efficacy and challenges of this model in China. In this study, we explore these challenges and describe how cooperation between law enforcement and health departments can meet the needs of PWUD. Methods In 2015, we conducted semi-structured, in-depth interviews with all four staff members and 16 clients of the Ping An Centre No. 1 for community-based drug treatment, three local police officers and three officials from the local Centre for Disease Control. Interviews explored obstacles in implementing community-based drug dependence treatment and efforts to resolve these difficulties. Transcripts were coded and analyzed with qualitative data analysis software (MAXQDA 11). Results We identified three challenges to community-based drug treatment at the Ping An Centre No. 1: (1) suboptimal coordination among parties involved, (2) a divergence in attitudes towards PWUD and harm reduction between law enforcement and health officials and (3) conflicting performance targets for police and health officials that undermine the shared goal of treatment. We also identified the take-home methadone maintenance treatment model at the Ping An Centre No. 1 as an example of an early successful collaboration between the police, the health department and PWUD. Conclusions To overcome barriers to effective community-based drug treatment, we recommend aligning the goals of law enforcement and public health agencies towards health-based performance indicators. Furthermore, tensions between PWUD and police need to be addressed and trust between them fostered, using community-based treatment centres as mediators. The preliminary success of the take-home methadone maintenance treatment pilot can serve as an example of how collaboration with the police and other government agencies can meet the needs of PWUD and contribute to the success of community-based treatment.

Abstract
Drug abuse and co-occurring infections are associated with significant morbidity and mortality. Asian countries are particularly vulnerable to the deleterious consequences of these risks/problems, as they have some of the highest rates of these diseases. This review describes drug abuse, HIV, and hepatitis C (HCV) in Asian countries. The most commonly used illicit drugs include opioids, amphetamine-type stimulants (ATS), cannabis, and ketamine. Among people who inject drugs, HIV rates range from 6.3 % in China to 19 % in Malaysia, and HCV ranges from 41 % in India and Taiwan to 74 % in Vietnam. In the face of the HIV epidemics, drug policies in these countries are slowly changing from the traditional punitive approach (e.g., incarcerating drug users or requiring registration as a drug user) to embrace public health approaches, including, for example, community-based treatment options as well as harm reduction approaches to reduce needle sharing and thus HIV transmission. HIV and HCV molecular epidemiology indicates limited geographic diffusion. While the HIV prevalence is declining in all five countries, use of new drugs (e.g., ATS, ketamine) continues to increase, as well as high-risk sexual behaviors associated with drug use-increasing the risk of sexual transmission of HIV, particularly among men who have sex with men. Screening, early intervention, and continued scaling up of therapeutic options (drug treatment and recovery support, ART, long-term HIV and HCV care for drug users) are critical for effective control or continued reduction of drug abuse and co-infections.

Abstract
Objective: To assess concurrent heroin use and correlates among Methadone Maintenance Treatment (MMT) clients in Guangdong Province, China. Method: Demographic and drug use data were collected with a structured questionnaire, and MMT information was obtained from the MMT clinic registration system in Guangdong. Human immunodeficiency virus (HIV-) and hepatitis C virus (HCV) infected status and urine morphine results were obtained from laboratory tests. Logistic regressions were employed to investigate the factors associated with concurrent heroin use. Results: Among the 6848 participants, 75% continued using heroin more than once during the first 12 months after treatment initiation. Concurrent heroin use was associated with inharmonious family relationship (OR (odds ratio) = 1.49, 95% CI (confidence intervals): 1.24–1.78), HIV positivity (OR = 1.25, 95% CI: 1.01–1.55), having multiple sex partners (OR = 1.34, 95% CI: 1.07–1.69), having ever taken intravenous drugs (OR = 0.81, 95% CI: 0.69–0.95), higher maintenance dose (OR = 1.13, 95% CI: 1.01–1.28) and poorer MMT attendance (OR<20% = 1.32, 95% CI: 1.13–1.53; OR20%– = 1.33, 95% CI: 1.14–1.54; OR50%– = 1.69, 95% CI: 1.44–2.00). Among those who used heroin concurrently, the same factors, and additionally being older (OR35– = 1.26, 95% CI: 1.11–1.43; OR≥45 = 1.63, 95% CI: 1.30–2.05) and female (OR = 1.60, 95% CI: 1.28–2.00), contribute to a greater frequency of heroin use. Conclusions: Concurrent heroin use was prevalent among MMT participants in Guangdong, underscoring the urgent needs for tailored interventions and health education programs for this population.

Abstract
BACKGROUND Despite widespread implementation of compulsory treatment modalities for drug dependence, there has been no systematic evaluation of the scientific evidence on the effectiveness of compulsory drug treatment. METHODS We conducted a systematic review of studies assessing the outcomes of compulsory treatment. We conducted a search in duplicate of all relevant peer-reviewed scientific literature evaluating compulsory treatment modalities. The following academic databases were searched: PubMed, PAIS International, Proquest, PsycINFO, Web of Science, Soc Abstracts, JSTOR, EBSCO/Academic Search Complete, REDALYC, SciELO Brazil. We also searched the Internet, and article reference lists, from database inception to July 15th, 2015. Eligibility criteria are as follows: peer-reviewed scientific studies presenting original data. Primary outcome of interest was post-treatment drug use. Secondary outcome of interest was post-treatment criminal recidivism. RESULTS Of an initial 430 potential studies identified, nine quantitative studies met the inclusion criteria. Studies evaluated compulsory treatment options including drug detention facilities, short (i.e., 21-day) and long-term (i.e., 6 months) inpatient treatment, community-based treatment, group-based outpatient treatment, and prison-based treatment. Three studies (33%) reported no significant impacts of compulsory treatment compared with control interventions. Two studies (22%) found equivocal results but did not compare against a control condition. Two studies (22%) observed negative impacts of compulsory treatment on criminal recidivism. Two studies (22%) observed positive impacts of compulsory inpatient treatment on criminal recidivism and drug use. CONCLUSION There is limited scientific literature evaluating compulsory drug treatment. Evidence does not, on the whole, suggest improved outcomes related to compulsory treatment approaches, with some studies suggesting potential harms. Given the potential for human rights abuses within compulsory treatment settings, non-compulsory treatment modalities should be prioritized by policymakers seeking to reduce drug-related harms.

Abstract
BACKGROUND Methadone maintenance treatment (MMT) reduces the harms of opioid use disorder and is being rapidly scaled-up in China. This study evaluated the real-world implementation of MMT system in Wuhan, China. METHODS Data extracted from electronic medical records collected in 2010 on 8811 patients were used to compute for each patient indices of the prescribed and consumed daily methadone doses, an adherence index, dose adjustments following missed doses, the rates of opiate positive urine tests, self-reported drug use, injection drug use (IDU), and the duration of MMT exposure. FINDINGS The modal daily doses prescribed were 60 mg and above for 68.5% of patients. Adherence was variable: 51% of patients attended less than 60% and 26% attended 80-100% of their treatment days; and patients with long MMT exposure had significantly higher adherence rates than patients with short MMT exposure. The differences between doses dispensed immediately before and after the interruption in dosing days ranged from 0 to 7 mg, independently of the length of the interruption or the prescribed dosing level. The overall rate of opiate positive tests was 20%; 45% of patients had at least one opiate positive test; 29% reported past month drug use and 53% of them reported past month IDU. Adherence and MMT exposure duration correlated significantly with the proportion of opiate negative urine tests (r=0.355, p<0.001; r=0.351, p<0.001, respectively). Treatment for males and females was comparable. CONCLUSIONS Provision of safe methadone dosing after absences and improving daily attendance are identified as priority improvement areas.

Abstract
OBJECTIVE Client adherence is vital for effective methadone maintenance treatment (MMT). This study explores the pattern and associated factors of client adherence, drop-out and re-enrolment in the Chinese MMT programme over the period of 2006-2013. METHODS This retrospective study was conducted in 14 MMT clinics in Guangdong Province, China. We employed Kaplan-Meier survival analysis to estimate the rates of drop-out and re-enrolment of MMT clients and multivariate Cox regression to identify associated factors. RESULTS Among 1,512 study participants, 79% have experienced 'drop-out' during the 7-year study period. However, 82% 'dropped-out' clients resumed treatment at a later time. Low education level (junior high or below versus otherwise, HR = 1.21, 1.05-1.40), low methadone dosage in the first treatment episode (<50 ml versus ≥50 ml, HR = 1.84, 1.64-2.06) and higher proportion of positive urine test (≥50% versus<50%, HR = 3.72, 3.30-4.20) during the first treatment episode were strong predictors of subsequent drop-outs of the participants. Among the 'dropped-out' clients, being female (HR = 1.40, 1.23-1.60), being married (HR = 1.19, 1.09-1.30), and having a higher proportion of positive urine tests in the first treatment episode (≥50% versus<50%, HR = 1.35, 1.20-1.51) had greater likelihood of subsequent re-enrolment in MMT. Clients receiving lower methadone dosage (first treatment episode <50 ml versus ≥50 ml, HR = 1.12, 1.03-1.23; the last intake before drop-out <50 ml versus ≥50 ml, HR = 1.16, 1.04-1.30) were also more likely to re-enrol. CONCLUSION Persistent cycling in-and-out of clients in MMT programmes is common. Insufficient dosage and higher proportion of positive urine samples in the first treatment episode are the key determinants for subsequent client drop-out and re-enrolment. Interventions should target clients in their early stage of treatment to improve retention in the long term.

Genotype Distribution and Molecular Epidemiology of Hepatitis C Virus in Hubei, Central China. PLoS One 2015; 10:e0137059.

Abstract
Background Little is known about the molecular epidemiology of hepatitis C virus (HCV) infection in Central China. Methodology/Principal Findings A total of 570 patients from Hubei Province in central China were enrolled. These patients were tested positive for HCV antibody prior to blood transfusion. Among them, 177 were characterized by partial NS5B and/or Core-E1 sequences and classified into five subtypes: 1b, 83.0% (147/177); 2a, 13.0% (23/177); 3b, 2.3% (4/177); 6a, 1.1% (2/177); 3a, 0.6% (1/177). Analysis of genotype-associated risk factors revealed that paid blood donation and transfusion before 1997 were strongly associated with subtypes 1b and 2a, while some subtype 2a cases were also found in individuals with high risk sexual behaviors; subtypes 3b, 6a, and 3a were detected only in intravenous drug users. Phylogeographic analyses based on the coalescent datasets demonstrated that 1b, 2a, 3b, and 6a were locally epidemic in Hubei Province. Among them, subtype 1b Hubei strains may have served as the origins of this subtype in China, and 2a and 3b Hubei strains may have descended from the northwest and southwest of China, respectively, while 6a Hubei strains may have been imported from the central south and southwest. Conclusion/Significance The results suggest that the migration patterns of HCV in Hubei are complex and variable among different subtypes. Implementation of mandatory HCV screening before donation has significantly decreased the incidence of transfusion-associated HCV infection since 1997. More attention should be paid to intravenous drug use and unsafe sexual contact, which may have become new risk factors for HCV infection in Hubei Province.

Abstract
Objective Methadone maintenance treatment (MMT) was introduced to China in 2004 to reduce the harm of injecting drug users (IDUs). However, little is known about continued drug use, especially methamphetamine (MAMP), among MMT patients. Methods A survey was conducted among patients attending five major MMT clinics in Dehong Prefecture in 2014 to investigate the heroin and MAMP use and their associated risk factors. Participants were administered with face-to-face interviews, and urine tests for morphine and MAMP. Results A total of 2,121 were eligible and participated in the study. Among them, 220 (10.4%) were only positive for morphine, 12.9% were only positive for MAMP, and 196 (9.2%) were positive for both morphine and MAMP. Compared with neither use of heroin nor MAMP during MMT, heroin use (not using MAMP) was associated with ethnicity, shorter duration of MMT, lower dose of methadone, and having had no more than two sex partners in the past year; MAMP use (not using heroin) was associated with ethnicity, longer duration of MMT, higher dose of methadone and being aged <30 years (vs. ≥50 years); use of both heroin and MAMP was associated with being Dai minority (vs. Han), a marital status of divorced or widowed, having used drugs for ≥10 years and shorter duration of MMT. Conclusion These findings indicate the complexity in the treatment of heroin users and underscore the importance in prescribing appropriate methadone dosages in order to reduce both heroin and MAMP use.

Barriers and Potential Improvements for Needle and Syringe Exchange Programs (NSPs) in China: A Qualitative Study from Perspectives of Both Health and Public Security Sectors. PLoS One 2015; 10:e0130654. [PMID: 26114556 PMCID: PMC4482722 DOI: 10.1371/journal.pone.0130654] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2014] [Accepted: 05/25/2015] [Indexed: 11/18/2022] Open
Abstract
This study explores the acceptability, the barriers to the implementation of needle and syringe exchange programs (NSPs) and the potential improvement strategies in China from the perspectives of governmental health and public security officials. Purposive sampling was used for recruitment of participants who had been involved in NSPs implementation. Semi-Structured individual interviews were conducted in Mandarin to address three aspects of NSPs: (1) participants’ attitudes towards NSPs, (2) participants’ opinions on the effectiveness and barriers of NSPs, and (3) suggestions for improving the program. Content analysis was used to analyse the translated interview data. A total of 68 participants from 12 Hunan counties were interviewed (34 from each of the Bureau of Health and the Narcotic Division). Both groups recognised the importance and effectiveness of NSPs in HIV prevention, but public security officials regarded NSPs as a temporary intervention in place of punitive measures. Most health officials (32/34) regarded the main barriers to its implementation as administrative and structural, whereas participants from Narcotics Division (n=24) questioned the legitimacy of NSPs and concerned about the poor management of drug users’ risk behaviours. Close cooperation between the health and public security sectors, engagement of the drug user community and an enabling policy environment were reportedly to be critical for potential improvements of NSPs in China. Misconceptions about NSPs encourage drug users’ addictive behaviour, and an unclear leadership and insufficient support de-motivate the participants from the Bureau of Health and the Narcotics Division to actively support the program implementation.

Abstract
BACKGROUND People who inject drugs (PWID) have a high prevalence of mental health problems (e.g., depression) which compromise the effects of HIV prevention. We investigated the prevalence of depression and associated factors among PWID in Dazhou, China. METHODS Anonymous face-to-face interviews were administered to eligible participants by well-trained doctors. The Center of Epidemiological Studies Depression Scale (CES-D) was used to measure depression, using hierarchical linear regression models. RESULTS Among the 257 participants, 7.0%, 11.3%, and 75.1% were probable cases of mild (16 ≤ CES-D < 21), moderate (21 ≤ CES-D < 25), and severe (CES-D ≥ 25) depression, respectively. Hopefulness (standardized β = -0.34, p < 0.001) and emotional family support (β = -0.21, p < 0.001) were negatively associated, whereas severity of drug dependence (β = 0.12, p = 0.034) and unmet service needs (β = 0.20, p < 0.001) were positively associated, respectively, with CES-D scores. The adjusted analysis showed that resilience was negatively associated with CES-D, but it was not selected by the stepwise model containing hopefulness and emotional family support. Protective factors (i.e., hopefulness and emotional family support) and risk factors (i.e., severity of drug dependence and unmet service needs) remained significant in the same regression model. CONCLUSION Protective and risk factors were independently associated with depressive symptoms. Integrated interventions covering basic and psychosocial needs for PWID are warranted. Such interventions should strengthen emotional family support and cultivate positive factors such as hopefulness.

Abstract
BACKGROUND AND AIMS To decrease infectious disease transmission, China is expanding methadone maintenance treatment (MMT). This study evaluated the prevalence of hepatitis C virus (HCV) infection at MMT entry, seroconversion rates after admission and potential risk factors for HCV seroconversion during MMT in Wuhan, China. DESIGN Cross-sectional survey of all patients entering MMT and prospective follow-up of patients HCV seronegative at admission. SETTING All MMT clinics in Wuhan, China. PARTICIPANTS A total of 12 755 opiate-dependent individuals entering MMT between May 2006 and June 2011; 1200 participants HCV seronegative at admission were followed. MEASUREMENTS Serological tests for HCV and self-report data on risk behaviors at MMT admission; urine toxicology results and repeated assessments of serological status and risk behaviors during treatment on patients HCV seronegative at admission. FINDINGS HCV seroprevalence at admission was 72.1% [95% confidence interval (CI) = 71.3-72.9%] and 555/1200 (46.3%, 95% CI = 43.5-49.1%) patients seroconverted to HCV during MMT. The mean time to HCV seroconversion was 3 (95% CI = 2.84-3.07) years with a cumulative seroconversion rate of 34.5 (95% CI = 31.5-36.9) per 100 person-years. Significant predictors of HCV conversion included injection drug use in the past 30 days [relative hazard (RH) 2.0, 95% CI: 1.6 - 2.4, P=0.002] and the rate of opiate-positive urine tests during MMT (RH 2.0, 95% CI = 1.3-3.1, P<0.001). CONCLUSIONS Methadone maintenance treatment patients in Wuhan, China show a high prevalence of hepatitis C virus at admission (72.1%) and a high rate of seroconversion during treatment (46.3%). Seroconversion is associated with continuing injection drug use.

Abstract
The HIV epidemic in East Asia started relatively late compared to the rest of the world. All countries or areas, except for North Korea, had reported HIV and AIDS cases, with China being the major contributor to the epidemic. Though initially driven by injecting drug use in China, East Asia did not experience an explosive spread. Strong commitment in China and early harm reduction programs in Taiwan managed to reduce transmission substantially among injecting drug users. In contrast to China and Taiwan, injection drug use has accounted just a little, if not at all, for the spread of HIV in other East Asian counties. However, following a global trend, sexual contact has become a major route of infection across the region. While much progress has been achieved in this region, with the epidemic among other key populations relatively stable, the emerging epidemic through sex between men is a growing concern. Recent estimates suggest that HIV prevalence among men who have sex with men (MSM) has reached 6.3 % in China, 7.5 % in Mongolia, and ranges between 8.1 %-10.7 % in Taiwan and between 2.7 %- 6.5 % in South Korea. In Japan, 74 % of male HIV cases were among MSM in 2012, while Hong Kong has witnessed a sharp increase of HIV cases among MSM since 2004. There is urgent need to address issues of discrimination and stigma toward homosexuality, and to strengthen the strategies to reach and care for this population.

Abstract
In 1981, when acquired immune deficiency syndrome (AIDS) was first observed among persons who inject drugs, almost all US states had laws criminalizing the possession and distribution of needles and syringes for injecting illicit drugs. We reviewed changes to these laws to permit 'syringe exchanges' and the provision of public funding for such programs. Most of the changes in law occurred during the 1990s, 5-10 years later than in many other countries. Public funding of syringe exchanges is associated with lower rates of human immunodeficiency virus (HIV) infection, greater numbers of syringes distributed (a possible causal mechanism), and greater numbers of health and social services provided. Experience in the United states may prove useful in other countries: state, provincial, and local governments may need to move ahead of central governments in addressing HIV infection among persons who inject drugs.

Abstract
AIM To describe trends in the HIV epidemic among drug users (DUs) in China from 1995 to 2011. DESIGN, SETTING AND PARTICIPANTS Data sets from China's national HIV/AIDS case reporting and sentinel surveillance systems as of December 2011 were used separately for descriptive analysis. MEASURES Changes in the geographic distribution of the number of HIV cases and HIV prevalence among injecting drug users (IDUs) and non-IDUs were examined. We also analysed changes in HIV prevalence among the broader DU population, and drug use-related behaviours including types of drugs used, recent injecting and recent needle sharing in the context of the rapid scale-up of DU sentinel sites and national harm reduction programmes. FINDINGS The HIV epidemic among China's DUs is still highly concentrated in five provinces. Here, HIV prevalence peaked at 30.3% [95% confidence interval (CI)=28.6, 32.1] among IDUs in 1999, and then gradually decreased to 10.9% (95% CI=10.6, 11.2) by 2011. We observed a rapid increase in the use of 'nightclub drugs' among DUs from 1.3% in 2004 to 24.4% in 2011. A decline in recent needle sharing among current IDU from 19.5% (95% CI=19.4, 19.6) in 2006 to 11.3% (95% CI=11.2, 11.4) in 2011 was found to be correlated with the rapid scale-up of methadone maintenance treatment (MMT; r(4)=-0.94, P=0.003) harm reduction efforts. CONCLUSIONS While HIV prevalence and needle sharing among current injecting drug users in China have declined dramatically and are correlated with the scale-up of national harm reduction efforts, the recent, rapid increased use of 'nightclub drugs' presents a new challenge.
