Objective@#To explore the survival status and influencing factors on former plasma donors (FPD) living with HIV/AIDS after initiation of antiretroviral therapy (ART) during 2002-2017 in Henan province.@*Methods@#A retrospective study was conducted, using data from the ART database of national comprehensive HIV/AIDS information system. The inclusion criteria on patients would include HIV/AIDS cases with current residence in Henan province, route of infection being blood-borne (plasma collection), initiation of ART between 2002 and 2017, and 15 year-olds or above. According to the time of initation on antiviral treatment, observation was carried on between January 1, 2002 and December 31, 2017. Outcome of observation was defined as death caused by AIDS or related diseases. Life Table was used to estimate the survival rate and Kaplan-Meier method was used to draw the survival curve. Log-rank test was used to compare the univariate intergroup survival rates while Cox proportional hazards regression model was used to analyze the influencing factors on survival status among deaths due to AIDS or related diseases. Excel 2010 software and SPSS 23.0 software was used for data cleaning and statistical analysis.@*Results@#A total of 25 825 HIV/AIDS patients were enrolled in this study. During the follow-up period, the overall mortality was 3.9/100 person year (8 354/214 796.3), among all the patients. The accumulate survival rates of 1 year, 4 years, 8 years, 12 years and 16 years after the initiation of ART were 91.2%, 80.1%, 71.2%, 65.7% and 61.5%, respectively. The results from the multivariate Cox proportional hazards regression model analysis showed that male vs. female (aHR=1.46, 95%CI: 1.39-1.53); aged 45-49 years group and aged 60 and older years group of initiating ART vs. aged 15-44 years group of initiating ART respectively (aHR=1.47, 95%CI: 1.40-1.54; aHR=2.50, 95%CI: 2.22-2.81); other marital status vs. being married or under cohabitation (aHR=1.29, 95%CI: 1.21-1.36); baseline CD4+T cells counts (CD4)<50, 50-199 and 200-349 cells/μl respectively vs. baseline CD4≥350 cells/μl (aHR=4.50, 95%CI: 4.14- 4.89; aHR=2.49, 95%CI: 2.31-2.69; aHR=1.44, 95%CI: 1.33-1.56); number of opportunistic infections at baseline were one case, 2-3 cases and 4-5 cases respectively vs. non opportunistic infections cases at baseline (aHR=1.17, 95%CI: 1.06-1.29; aHR=1.47, 95%CI: 1.35-1.59; aHR=1.74, 95%CI: 1.60-1.89); taking TMP-SMZ vs. not taking TMP-SMZ (aHR=0.69, 95%CI: 0.65- 0.73).@*Conclusions@#The 16-year accumulate survival rate was 61.5% among FPD living with HIV/AIDS after initiation of ART, during 2002 to 2017 in Henan province. The risk factors for FPD death case would include: being males, aged 45 and older years at the initiation of ART, baseline CD4<350 cells/μl and the number of baseline opportunistic infections cases ≥1.

Objective: To understand the disease progression and human leukocyte antigen (HLA) gene polymorphism of HIV-infected persons without disease progress for long term, also known as long-term non-progressors (LTNPs), in Henan province. Methods: A retrospective study was conducted in 48 LTNPs with complete detection and follow-up information during 2011-2016 in Henan. Changes of CD(4)(+)T cells counts (CD(4)) and viral load (VL) during follow-up period were discussed. Polymerase chain reaction-sequence-specific oligonucleotide probe (PCR-SSOP) was used for the analyses of HLA-A, HLA-B and HLA-DRB1 alleles between LTNPs and healthy controls. Results: From 2011 to 2016, forty-eight LTNPs showed a decrease of the quartile (P(25)-P(75)) of CD(4) from 601.00 (488.50-708.72)/μl to 494.00 (367.00-672.00)/μl, and the difference was significant (P<0.05). The increase of the quartile (P(25)-P(75)) of log(10)VL from 3.40 (2.87-3.97) to 3.48 (2.60-4.37), but the difference was not significant (P>0.05). HLA polymorphism analysis revealed that HLA-B*13:02 and HLA-B*40:06 were more common in LTNPs (P<0.05), while HLA-B*46:01 and HLA-DRB1*09:01 were more common in healthy controls (P<0.05). Conclusions: The CD(4) of LTNPs in Henan showed a downward trend year by year. HLA-B*13:02 and B*40:06 might be associated with delayed disease progression for HIV infected persons in Henan.

<p><b>OBJECTIVE</b>To understand the prevalence of informing doctors of the HIV infection status during medical care seeking and influential factors among people living with HIV/AIDS.</p><p><b>METHODS</b>The study was conducted among people living with HIV/AIDS in 7 provinces in China, including those receiving HIV test, HIV counsel and HIV infection treatment. The data were analyzed with software SAS 9.2. Chi-square test was used to compare the informing rates in patients with different characteristics. Univariate and multivariate logistic regression analyses were conducted to identify the influential factors.</p><p><b>RESULTS</b>Of the 2 432 HIV/AIDS patients, 49.7% (716/1 442) didn't inform the doctors of their HIV infection status actively. The non-active informing rate was 51.9% (559/1 077) in males, 62.9% (212/337) in age group 18-30 years old, 58.1% (555/955) in those with a educational level >primary school, 65.7% (241/367) in those working in private/joint companies or the self employed and 62.5% (197/315) in those living in small cities. The non active informing rate was highest in those infected through sexual contact (66.3%, 275/415). Multivariate logical regression analysis indicated that those infected through illegal blood donation would like to inform of the HIV infection status actively (OR=0.083, 95% CI: 0.049-0.141) , but those working in private/joint companies or the self employed would like not to inform of the HIV infection status actively (OR=1.531, 95% CI: 1.017-2.304).</p><p><b>CONCLUSION</b>The non active informing rate of HIV infection status was high in people living with HIV/AIDS.

<p><b>OBJECTIVE</b>To understand the one-year effect of HCV/HIV co-infected patients who had received AIDS second-line antiretroviral treatment after failure virologically, on the first-line therapy.</p><p><b>METHODS</b>HCV and HIV antibody positive patients who had experienced virological failure but received at least one-year AIDS first-line treatment, were recruited from May to October 2012 in Xincai, Queshan and Weishi of Henan province. 6-months and 12-months follow-up programs were carried out after the regimen had been changed to AIDS second-line antiretroviral treatment, CD4⁺ T lymphocyte count, HIV-1 virus load and HIV-1 drug resistance were performed.</p><p><b>RESULTS</b>Eighty-one cases of eligible patients were selected and followed by an amelioration of CD4 median at 6-month and 12-month follow-up period. Data showed that the baseline, 6-months and 12-months CD4 medians were 266 cells/µl, 275 cells/µl and 299 cells/µl (χ² = 8.214, P = 0.009). The ratio of HIV virus load suppression patients at 6-months and 12-months follow-up increased to 46.84% and 50.00%, respectively. Frequencies of HIV drug resistance also decreased at the baseline, 6-months and 12-months, with ratios as 66.67%, 26.58% and 27.63% (χ² = 29.362, P = 0.000), respectively. Ratios of patients that holding NRTI and NNRTI drug resistance appeared coinstantaneous decrease at the baseline, 6-months and 12-months, as 51.85%, 18.99% and 17.11% (χ² = 14.230, P = 0.005). At the baseline, the ratios of patients resisted to 3TC, ABC and FTC were all more than 50%, with AZT, D4T and DDI between 41%-44% while TDF appeared as 33.33%, then all of them declined to 12%-18% at the 6-month and 12-month follow-up periods. 65.43% of the patients resisted to both NVP and EFV but declined to 24%-27% at 6 months and 12 months.</p><p><b>CONCLUSION</b>HCV/HIV co-infected patients experienced virological failure of AIDS first-line therapy were ameliorated after changing to use second-line antiretroviral treatment for 6-months, but did not show constant positive effect at the 12-month end point.</p>

<p><b>OBJECTIVE</b>This study was aimed to investigate the ways of spousal notification and its associated factors among HIV discordant couples.</p><p><b>METHODS</b>A face-to-face questionnaire survey was conducted in Henan, Yunnan, Sichuan provinces and Guangxi Zhuang Autonomous Region in China. Information including democratic characteristics, knowledge and behaviors correlated with HIV infections and ways of HIV infectious status notification was collected. 'Data information system' on AIDS prevention and control was used to collect information on the transmission route.</p><p><b>RESULTS</b>A total of 770 pairs of HIV discordant couples were studied, among which 414 (53.77%) HIV positive respondents reported as self-notification, with another 44.68% were notified by medical staff. Factors associated with ways of notification included gender, nation, transmission route, and education level. HIV positive respondents who were female, under Han nationality, being paid blood donors, having had higher education level, were more likely to inform their HIV negative spouse by themselves.</p><p><b>CONCLUSION</b>Nationality and HIV transmission route of the HIV positive individuals were found as significant factors associated with ways of spousal notification. Therefore, HIV discordant couples notification should be strengthened, especially in the Minority-living areas and areas where HIV transmission was predomint through sexual contact and/or via injected drug use.</p>

<p><b>OBJECTIVE</b>To compare the HIV suppression rate after initiating antiretroviral treatment(ART) among AIDS patients at different immunological levels and to analyze the related factors.</p><p><b>METHODS</b>Data on AIDS patients initially starting antiretroviral therapy during 2008 and 2013 were collected from Chinese HIV/AIDS integrated control system. All the participants were divided into early treatment group(baseline CD4(+)T cell counts between 351/µl and 500/µl) and conventional treatment group(baseline CD4(+)T cell counts ≤ 350/µl). The rates of comprehensive virologic suppression at different time nodes after the initiation of ART were analyzed accordingly. Unconditional logistic regression model was adopted to examine the factors associated with the failure of viral suppression after 6 months after initiation of ART.</p><p><b>RESULTS</b>A total of 16 103 cases were selected, among which, 1 581 cases were early treatment group, and 14 522 cases were conventional treatment group. A total of 9 428 cases were males, 6 675 cases were females, and the sex ratio was 1.41: 1. The age was 47.2 ± 11.7, and 71.55% (11 522/16 103) of cases were married or cohabiting, 57.22% (9 214/16 103) were transmitted by blood. 81.26% (13 086/16 103) were cures in the township or village treatment institution, and 77.17% (12 426/16 103) received the ART regimen as Stavudine(D4T) or Zidovudine(AZT)+Lamivudine(3TC)+Nevirapine(NVP) or Efevirenz(EFV). After 0.5, 1, 2, 3, 4, 5 and 6 years after the initiation of ART, the rates of virologic suppression in the conventional treatment cohort were 72.6% (3 008/4 144), 73.9% (4 758/6 443), 74.1% (3 641/4 915), 74.9% (2 819/3 766), 76.1% (1 729/2 272) and 78.2% (492/629), respectively. While the rates of viral suppression in the early treatment cohort at the same time nodes were 65.5% (315/481), 65.4% (448/685), 68.8% (223/324), 66.0% (155/235), 71.4% (110/154) and 61% (30/49), respectively, and the differences between the two groups were significant (P < 0.05) except at the fourth year. Non-conditional logistic regression analysis showed that in the conventional treatment group, factors associated with low HIV suppression rate were male (OR = 1.23, 95%CI:1.07-1.42) , longer time interval from confirmed HIV infection to received ART (OR = 1.26, 95%CI:1.16-1.36) , using D4T/AZT+ DDI +NVP/EFV as initial treatment regimen (OR = 3.00, 95%CI:2.26-3.98) and nearly missing doses for 7 days at treatment of six months (OR = 1.97, 95%CI:1.22-3.18) and factors associated with high HIV suppression rate were infected through homosexual transmission route (OR = 0.57, 95%CI:0.35-0.90) and treated in the county level medical institution or above (OR = 0.61, 95%CI:0.50-0.75) . Among early treatment group, cases who received treatment at county level medical institution or above had high HIV suppression rate (OR = 0.43, 95%CI:0.23-0.80) and objects with longer time interval from confirmed HIV infection to receive ART had low HIV suppression rate (OR = 1.43, 95%CI:1.09-1.88).</p><p><b>CONCLUSION</b>The viral suppression efficacy among AIDS patients with different baseline immunologic levels after treatment was similarly satisfactory. AIDS cases who received ART at county level medical institution or above had better viral suppression effect and patients with longer time interval from confirmation to treatment had poor HIV suppression effect.</p>
