RESUMEN

It remains unclear if China's current HIV antibody testing algorithm misses a substantial number of HIV infected individuals. Of 196 specimens with indeterminate or negative results on HIV western blot (WB) retrospectively examined by HIV-1 nucleic acid test (NAT), 67.57% (75/111) of indeterminate WB samples, and 16.47% (14/85) of negative WB samples were identified as NAT positive. HIV-1 loads in negative WB samples were significantly higher than those in indeterminate WB samples. Notably, 86.67% (13/15) of samples with negative WB and double positive immunoassay results were NAT positive. The rate of HIV-1 infections missed by China's current HIV testing algorithm is unacceptably high. Thus, China should consider using NAT or integrating fourth generation ELISA into current only antibodies-based HIV confirmation. J. Med. Virol. 88:1462-1466, 2016. © 2016 Wiley Periodicals, Inc.

RESUMEN

BACKGROUND: Outcomes of methadone maintenance treatment (MMT) in the management of opioid dependency can be impaired by poor adherence and retention, concomitant drug use, poor adjustment of methadone dosage, and low levels of awareness regarding methadone among drug users, among other factors. This study investigated the effects of intensive blended treatment literacy and psychoeducation on treatment compliance, methadone dose, and heroin use among MMT clients in China. METHODS: A total of 492 MMT clients who tested positive for urine morphine at least once during a 12-week intervention period preceding the study were recruited from 16 MMT clinics. Employing a client-centred approach, a blended treatment literacy and psychoeducation intervention was then implemented between March and June 2014, comprising (1) intensified methadone treatment literacy sessions; (2) participatory goal setting; (3) continuous adherence monitoring and support; and (4) engagement of both peers and doctors in delivering psychoeducation. Wilcoxon signed-rank test was used to compare urine morphine positive rates, daily methadone dosage, and the number of days that clients successfully accessed methadone before and during the intervention. RESULTS: During the intervention, urine morphine positive rates reduced to 27% from 49.3% previously; p < 0.001. In response to client needs, methadone dosages increased among 74% of participants, remained unchanged among 12.0%, and reduced among 13.4% during the intervention. In addition, the average daily methadone dose increased from 63.0 to 72.6 mg; p < 0.001, while the average number of days that clients successfully accessed methadone increased from 69.4 to 73.9 over a period of 12 weeks; p < 0.001. CONCLUSIONS: Blended treatment literacy and psychoeducation delivered by a combination of peers and doctors was associated with reduced heroin use, improved treatment adherence, and higher methadone doses among our sample of MMT clients.

RESUMEN

Effective health care models to scale up combination antiretroviral therapy (ART) are needed in rural southwestern China. We aimed to evaluate the ART treatment outcomes and their associations with patients' demographic characteristics and pre-treatment clinical features in a scaled-up provincial ART program serving eight heavily HIV-affected prefectures in Yunnan Province. We abstracted information from a computerized database for adults initiating ART between July 2007 and September 2008. Survival functions of mortality and treatment failure were calculated by age group, gender, transmission mode, and baseline CD4 count. Multivariable Cox regression analyses were conducted to find independent associations of various demographic and baseline clinical features with outcome variables. Of the 1967 patients in the mortality analysis, there were 110 deaths, of which 16 were coded as accidents or suicides. Adjusted hazard ratios (AHR) associated with mortality were greater for patients with baseline CD4 counts <100 cells/µl vs. patients with CD4 counts ≥200 cells/µl, for male vs. female, for single vs. married, and for those acquired HIV through injection drug use (IDU) vs. other modes of transmission. Successful treatment was 81.3% at six months after treatment started. Immunologic treatment failure was associated with baseline CD4 counts but not with demographic characteristics. Overall loss to follow-up rate was 2.1%. Collaboration between clinics and community networks are distinctive features of Yunnan's model for scaling up ART across a diverse, poor, and rural population. This study finds that the strategy can succeed even if 40% of the patients have a history of IDU.

RESUMEN

BACKGROUND: Oral pre-exposure prophylaxis (PrEP) is recommended as an additional prevention choice for men who have sex with men (MSM) at substantial risk of HIV. The aim of this study was to evaluate the extent, and reasons, for MSM's willingness to use oral PrEP in Wuhan and Shanghai, China. METHODS: Between May and December 2015, a cross-sectional survey was conducted among 487 MSM recruited through snowball sampling in physical locations frequented by MSM and through social media applications. Exploratory factor analysis was used to group reasons for being willing or not willing to use PrEP. Chi-square tests were used to explore bivariate associations between groupings of reasons for being willing or unwilling to use PrEP, and key sociodemographic and sexual-behavioral characteristics of MSM. RESULTS: Overall, 71.3% of respondents were willing to use PrEP. The most commonly reported reasons for being willing to use PrEP were preventing HIV infection (91.6%), taking responsibility for own sexual health (72.6%) and protecting family members from harm (59.4%). The main reasons for being unwilling to use PrEP were being worried about side effects (72.9%), the necessity of taking PrEP for long periods of time (54.3%) and cost (40.4%). Individual characteristics that influenced the type of reasons given for being willing or unwilling to use PrEP included being married to a woman, having a regular sex partner, rates of condom use with regular and casual sex partners, and the number of casual sex partners. CONCLUSION: The introduction of PrEP in China could benefit from promotion campaigns that emphasize its role in preventing HIV infection, in taking responsibility for own sexual health, and in protecting family members from potential harm. To reduce uptake barriers, it will be essential to provide accurate information to potential PrEP users about the mild and short-term nature of side effects, and the possibility of taking PrEP only during particular periods of life when the risk of HIV exposure might be highest.

RESUMEN

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.

RESUMEN

BACKGROUND: Conducted in Wuhan China, this study examined follow-up and health markers in HIV patients receiving care in two treatment settings. Participants, all men who have sex with men, were followed for 18-24 months. METHOD: Patients in a "one-stop" service (ACC; N = 89) vs those in standard care clinics (CDC; N = 243) were compared on HIV treatment and retention in care outcomes. RESULTS: Among patients with CD4 cell count ≦350 cells/µL, the proportion receiving cART did not differ across clinic groups. The ACC was favored across five other indicators: proportion receiving tests for CD4 cell count at the six-month interval (98.2% vs. 79.4%, 95% CI 13.3-24.3, p = 0.000), proportion with HIV suppression for patients receiving cART for 6 months (86.5% vs. 57.1%, 95% CI 14.1-44.7, p = 0.000), proportion with CD4 cell recovery for patients receiving cART for 12 months (55.8% vs. 22.2%, 95% CI 18.5-48.6, p = 0.000), median time from HIV confirmation to first test for CD4 cell count (7 days, 95% CI 4-8 vs. 10 days, 95% CI 9-12, log-rank p = 0.000) and median time from first CD4 cell count ≦350 cells/µL to cART initiation (26 days, 95% CI 16-37 vs. 41.5 days, 95% CI 35-46, log-rank p = 0.031). Clinic groups did not differ on any biomedical indicator at baseline, and no baseline biomedical or demographic variables remained significant in the multivariate analysis. Nonetheless, post-hoc analyses suggest the possibility of self-selection bias. CONCLUSIONS: Study findings lend preliminary support to a one-stop patient-centered care model that may be useful across various HIV care settings.
