OBJECTIVE: Antiretroviral drugs covered by medical insurance have been gradually used by people living with human immunodeficiency virus (PLWH) in recent years in China. This study aimed to analyze their willingness to pay (WTP) for antiretroviral drugs. METHODS: A mixed-methods study design involving a cross-sectional survey and in-depth interviews was conducted. A cross-sectional survey was performed to collect data on the general characteristics, economic status, antiretroviral therapy (ART) status, and WTP of PLWH in 18 Chinese cities from August 2022 to February 2023. Multivariate logistic regression was used to analyze the factors associated with WTP. Representatives of PLWH were interviewed via in-depth interviews, and the data were thematically analyzed. RESULTS: Among the 941 PLWH, 271 (28.80%) were willing to pay for antiretroviral drugs covered by medical insurance. For basic medical insurance for urban and rural residents, PLWH with the following characteristics were more willing to pay: an educational level of senior high school or technical secondary school, having an undergraduate degree or higher, frequently working away from their hometowns, and homosexual transmission. Off-farm workers and recipients of government medical aid were more unwilling to pay. For basic medical insurance for urban employees, PLWH with the following characteristics were more willing to pay: frequently working away from their hometowns; homosexual transmission; personal annual income ≥ 100,000 CNY; and adverse events of antiretroviral drugs. The main reasons for PLWH's WTP for antiretroviral drugs covered by medical insurance were that the drugs had fewer adverse events and were easier to administer. The main reasons for PLWH's unwillingness to pay were financial difficulties and privacy concerns. CONCLUSION Nearly one-third of PLWH are willing to pay for antiretroviral drugs covered by medical insurance. In the future, PLWH with a high WTP can be guided to use these drugs.

This paper aims to investigate whether good governance of a recipient country is a necessary condition and what combinations of factors including governance factor are sufficient for low prevalence of HIV/AIDS in HIV/AIDS aid recipient countries during the period of 2002-2010. For this, Fuzzy-set Qualitative Comparative Analysis (QCA) was used. Nine potential attributes for a causal configuration for low HIV/AIDS prevalence were identified through a review of previous studies. For each factor, full membership, full non-membership, and crossover point were specified using both author's knowledge and statistical information of the variables. Calibration and conversion to a fuzzy-set score were conducted using Fs/QCA 2.0 and probabilistic tests for necessary and sufficiency were performed by STATA 11. The result suggested that governance is the necessary condition for low prevalence of HIV/AIDS in a recipient country. From sufficiency test, two pathways were resulted. The low level of governance can lead to low level of HIV/AIDS prevalence when it is combined with other favorable factors, especially, low economic inequality, high economic development and high health expenditure. However, strengthening governance is a more practical measure to keep low prevalence of HIV/AIDS because it is hard to achieve both economic development and economic quality. This study highlights that a comprehensive policy measure is the key for achieving low prevalence of HIV/AIDS in recipient country.

OBJECTIVETo measure related cost, effectiveness and benefit of needle and syringe exchange (NSP) in two provinces of Southwest China.

METHODSBetween September 2012 and February 2013, program files and questionnaires were used to collect the information about cost, effectiveness and benefit of NSP during three program years (July 2009 to June 2010, July 2010 to June 2011, July 2011 to June 2012 ) in 31 counties of two provinces of Southwest China. Unit cost indicators including cost of providing per syringe and cost of covering per IDU, number of new HIV infections avoided by providing needle and syringe exchange were used to evaluate the effectiveness of NSP, and the benefit indicators included the fees for ART, hospitalization cost and follow up of new HIV infection avoided by NSP. NEAR model was used to calculate the cases averted by NSP. Chi-square test was used to analyze the different percentage of allocation areas between two provinces.

RESULTSBetween July 2009 and June 2012, 25 374 041 yuan were totally used for NSP. In province A, the top investment area was management (1 848 485 yuan) while it was comprehensive intervention (5 452 355 yuan) in province B. The cost of providing per syringe was 3.67 yuan, and it decreased from 6.96 to 4.01 in province A and decreased from 3.38 to 2.17 in province B with the increasing needles distributed. The cost of covering per IDU was 712.71 yuan and the unit cost decreased from 882.85 to 574.95 in province A and decreased from 760.48 to 625.07 in province B with the growing number of IDUs intervened. A total of 1 307 new HIV infection were avoided by providing NSP, so 19 413.96 yuan would be used to avoid per IDU infecting HIV. A total of 367 507 488 yuan of HIV/AIDS related expenditure were avoided by NSP and the cost benefit ratio was 14.48.

CONCLUSIONNSP has a good cost-benefit ratio and should be promoted.

OBJECTIVETo evaluate the cost effectiveness of HIV testing strategy in hospitals from 2006 to 2010 in Guangzhou.

METHODSAccording to the HIV test strategy costs and the number of HIV patients found in Guangzhou, following aspects were calculated as the total cost of HIV testing strategy in hospitals from 2006 to 2010 of Guangzhou, the cost of finding each HIV patient, and the cost of obtaining one quality adjusted life year (QALY) using Markov model.

RESULTSThe total HIV test strategy costs increased from 11 106.98 thousand Yuan to 25 105.58 thousand Yuan, and 4599 HIV positive patients were found due to this strategy. The cost-effectiveness of HIV testing were different in hospitals from 2006 to 2010 in Guangzhou. The lowest cost-effectiveness ratio of HIV testing strategy was 11 810 Yuan per HIV positive patient, the highest was 23 510 Yuan, and the average was 16 070 Yuan. According to the Markov model result, 7.2855 QALYs could be gained per HIV patient on average via HIV testing strategy in 113 hospitals in Guangzhou, and the cost of obtaining one QALY was 2210 Yuan.

CONCLUSIONThe cost effectiveness ratio of HIV testing strategy in hospitals in Guangzhou was significantly lower than the standard of WHO recommended, and it was cost-effective to carry out the HIV testing strategy in Guangzhou.

BACKGROUNDIn 2003, China's National Free Antiretroviral Treatment Program (NFATP) was initiated as a pilot, which covered only 100 HIV/AIDS patients. By 2011, the pilot had evolved into a nationwide program and had provided free treatment for over 150 000 patients. The objective of this study was to report and evaluate the progress of China's free antiretroviral treatment program.

METHODSThe NFATP Database was systematically reviewed and a total of 150 692 HIV/AIDS patients were included in this study. Program progress indicators including the number of treated HIV/AIDS patients, follow-up visit rate, CD4 test rate, and viral load test rate were summarized and examined over a calendar year to evaluate the progress of NFATP quantitatively and qualitatively.

RESULTSBy the end of 2011, a total of 150 692 HIV/AIDS patients had been treated through the NFATP and 122 613 of them were still on treatment. Of all patients, about 72% were enrolled during the past four years. The dominant transmission route was blood related in the early phase of the NFATP, but gradually changed to sexual contact. Besides quantitative improvements, progress indicators also demonstrated significant qualitative improvements that the program had made during the past 9 years.

CONCLUSIONSGreat achievement has been made by China's NFATP. China's experience indicates the importance of a comprehensive response to the success of its treatment program. However, to ensure the quality and sustainability of treatment in the long term, more attention and resources should be paid towards program management.

OBJECTIVETo perform cost-effectiveness analysis of interventions in female sex workers in Dehong prefecture in China, with an aim of providing evidence for rational resource allocation in female sex worker interventions in the future.

METHODSThe data of expenses for female sex worker interventions in Dehong from 2005 - 2007 were obtained through questionnaire survey. Meanwhile, the data from baseline survey in 2004, from surveillance of female sex workers from 2005 through 2007 as well as from the special survey on sexual transmission in 2007 were collected. Intervention effectiveness was estimated by using SEX 2.0 Tool recommended by UNAIDS. The cost-effectiveness ratio is calculated as the total cost divided by the number of estimated non-HIV patients due to these interventions.

RESULTSThe total cost for female sex worker interventions is 916 400 RMB from 2005 through 2007, and a total of 3297 female sex workers were effectively intervened in these three years. Thus, the actual intervention cost for each female sex worker (unit cost) is 277.9 RMB. If all the intervention work is performed as required, the predicted unit cost for female sex worker intervention would be 500.5 RMB. During the period of 2005 through 2007, 69 female sex workers had been successfully prevented from HIV infection; therefore, the cost-effectiveness ratio is 13 282 RMB.

CONCLUSIONIntervention among female sex workers is highly cost-effective.

OBJECTIVETo evaluate the feasibility and effectiveness of needle and syringe exchange program among a community of injecting drug users (IDUs) on AIDS prevention.

METHODSA quasi-experiment design was used in a controlled community intervention study. Needle and syringe exchange program was implemented for 10 months in IDUs of an intervention community, including peer education and health education, provision of free needles and syringes, and collecting back of used needles and syringes by trained peer educators and local health workers, whereas no intervention measure in a control community was instituted. Interviews with IDUs were conducted before and after intervention with a snowballing strategy to evaluate its effectiveness.

RESULTSA total of 428 and 429 IDUs were interviewed with structured questionnaire before and after intervention in intervention and control communities, respectively. Results revealed that awareness of HIV-related knowledge increased from 29.4% to 58.7% in the intervention community. Multivariate logistic regression analysis showed that awareness of HIV-related knowledge was higher in those who had read health education materials (OR = 2.93, 95% CI 2.12 - 4.04). As compared with the baseline data, frequency of sharing needles and syringes in past 30 days in the intervention community decreased from 48.9% to 20.4% in before intervention community (chi(2) = 41.02, P = 0.001), whereas there was no significant change in the control community. The causes of sharing needles and syringes in the intervention community included 'disable to get needle and syringe during the night', 'lack of needle and syringe when injecting at friend's home', 'not daring to buy needle and syringe for fear of being arrested' and 'no money to buy needle and syringe', declined markedly.

CONCLUSIONSNeedle and syringe exchange program was feasible and effective in reducing their risky drug injecting behavior among IDUs in communities. Such strategy should be adopted in the country to reduce rapid spread of HIV.

OBJECTIVETo investigate the anti-HIV effects of ampelopsin and its interaction with HIV-1 coreceptor CXCR4.

METHODSThrough anti-virus experiments in vitro, the inhibitory effect of ampelopsin on HIV-1 infection was verified. Chemotaxis assay was performed to show the ability to induce PBMCs migration by ampelopsin, RANTES and SDF-1alpha. Fluorescence labelling monoclonal antibody was utilized to observe the interaction of ampelopsin and CXCR4. Mice immunosuppressant model was also established to detail the role ampelopsin played in regulating cellular immunological functions.

RESULTSAmpelopsin could protect sensitive cells against HIV-1 infection and dramatically reduce HIV-1 antigen P24 expression. HIV-1SF33 attaching to MT-4 cells was interfered by ampelopsin, and the EC50 was 0.175 mg/mL for cellular protection and 0.024 mg/mL for P24 inhibition. At co-cultivating phase, EC50 was 0.229 mg/mL and 0.197 mg/mL respectively. Furthermore, the EC50 was 0.179 mg/mL and 0.348 mg/mL in acute infection. Human PBMCs migration was induced after being challenged with ampelopsin or chemokines, and synergistic action was observed during co-treatment. Ampelopsin alone resulted in maximal chemotaxis at 1 mg/mL. HIV-1 co-receptor CXCR4 on the surface of PBMCs was decreased by internalization, which indicated the effect of ampelopsin on CXCR4. About 70% CXCR4 was reduced by ampelopsin at 1 mg/mL. Ampelopsin also augmented cellular immunological functions in immunosuppressive mice.

CONCLUSIONAmpelopsin displays a strong inhibitive role during HIV-1 absorption, incubation and acute infection. These results are coincident with its immune enhancement.
