RESUMEN
Objective@#To understand the characteristics of HIV/AIDS epidemic in Guangxi Zhuang Autonomous Region (Guangxi) with a purpose to accurately provide scientific basis for prevention and control measures, 2010-2017.@*Methods@#Data were retrieved from case reporting cards of Guangxi during 2010 to 2017 through National HIV/AIDS Comprehensive Response Information Management System. Data was analyzed using epidemiological methods such number of cases, proportion and rate. χ2 test was used for statistical analysis.@*Results@#The HIV positive rate was 12.53 per ten thousand (85 182/67 959 000) in Guangxi during 2010 to 2017. The number of newly diagnosed HIV/AIDS cases and the number of death yearly respectively increased by 22.34%(2 602/11 648) and 32.83% (952/2 900) in 2011 compared with 2010, and both showed a six-year continuous downward trend (the number of newly diagnosed cases respectively 12 229 cases, 10 877 cases, 9 460 cases, 9 190 cases, 8 848 cases, 8 680 cases, and the number of death respectively 3 888 cases, 3 316 cases, 2 914 cases, 2 717 cases, 2 595 cases, 2 600 cases) from 2012 to 2017. But proportion of late discovery remained above 50.00% (50.53%-57.06%) for eight-years continuously. The ratio of male and female was 2.47 ∶ 1 (60 639/24 543). The ratio of males and females aged 50 and over was 2.71∶1 (28 654/10 557). Proportion of the cases in 25-49 years old group and 50 years old group accounting for 47.40%(40 377/85 182) and 46.03% (39 211/85 182) respectively. The occupation was farmers accounting for 68.40% (58 262/85 182), housekeeping, housework and unemployment accounting for 11.21% (9 546/85 182), student accounting for 0.86% (729/85 182). Heterosexual transmission accounted for 90.60% (77 171/85 182, homosexual transmission accounted for 3.13% (2 669/85 182), injection drug use transmission accounted for 4.60%(3 924/85 182) and mother-to-child transmission accounted for 0.73% (619/85 182).@*Conclusions@#The number of newly diagnosed cases and the number of death yearly showed a continuous downtrend for six-years from 2012 to 2017. However, proportion of late discovery remained above 50.00% for eight-years. The major route of infection was heterosexual transmission. With the change of HIV/AIDS newly epidemic mode in Guangxi, there are many new challenges for HIV/AIDS prevention and control work. Strategy of targeted intervention modes should be innovated for a new breakthrough.
RESUMEN
Objective To understand the characteristics of HIV infected persons without long term disease progress [also known as long term non-progressors (LTNPs)],and related factors in Guangxi Zhuang Autonomous Region (Guangxi).Methods Data of persons living with HIV and receiving no antiretroviral therapy in Guangxi by the end of 2016 were collected from the national HIV/AIDS comprehensive control and prevention information system of China.Results By the end of 2016,there were 313 LTNPs in Guangxi,accounting for 2.3 ％ of those being reported for more than 10 years,5.4％ of those being reported for more than 10 years and surviving,and 26.6％ of those being reported for more than 10 years,surviving and receiving no antiretroviral therapy.Among the LTNPs,87.2％(273) were men,94.9％ (297) were aged ≤ 40 years,32.3％ (101) were farmers,55.6％ (174) were single,divorced or widowed,69.3％ (217) were of Han ethnic group,68.1％ (213) were injecting drug users,and 52.1％ (163) were from custody facilities.Multiple logistic regression analysis indicated that factors associated with delayed disease progression included age ≤40 years (compared with age ＞40 years,aOR=1.55,95％ CI:1.31-3.12) and injection drug use (compared with sexual transmission,aOR=1.23,95％ CI:1.10-1.74).Conclusions A number of LTNPs existed in HIV-infected individuals in Guangxi.Further research are needed to identify the related factors,and it is necessary to conduct large sample size studies on host immunology,genetics and the virology of HIV to explore the related mechanism.

RESUMEN
Objective To investigate the effect of baseline CD4+T cell count (CD4) on drop-out of antiretroviral therapy (ART) in HIV infected persons.Methods Retrospective cohort was conducted in this study.HIV infected persons aged≥ 18 years and receiving free ART for the first time in Guangxi Zhuang Autonomous Region (Guangxi) from 2008 to 2015 were selected from the antiretroviral treatment database of National Comprehensive HIV/AIDS Information System,with follow-up conducted till May 30,2016.Cause-specific Cox proportional hazard models were used to evaluate effect of different CD4 on the drop-out of ART in the HIV infected persons.Results A total of 58 502 eligible study participants were included in this retrospective cohort study.The average drop-out ratio was 4.8/100 person-years.After controlling the following baseline covariates:age,sex,marital status,route of HIV infection,WHO clinical stage before ART,initial/current ART regiment,ART regiment adjustment,and year of initiating ART for potential confounding,the adjusted HR of drop-out for HIV infected persons with 200-cells/μl,351-cells/μl and ≥500 cells/μl were 1.110 (95％CI:1.053-1.171,P＜0.001),1.391 (95％CI:1.278-1.514,P＜0.001) and 1.695 (95％CI:1.497-1.918,P＜ 0.001),respectively,in risk for drop-out compared with those with baseline CD4 ＜200 cells/μ 1.Among the HIV infected persons,56.0％ (1 601/2 861) of drug withdrawal was due to poor compliance with medication.Conclusions With the increase of baseline CD4 when initiating ART,the risk for the drop-out in HIV infected persons increased significantly.To further reduce the drop-out of ART,it is important to take CD4 into account in initiating ART and to strengthen the health education on treatment compliancy and training for healthcare providers.
RESUMEN
Objective To understand the dynamic variation of BMI and influencing factors among HIV/AIDS patients receiving highly active anti-retroviral therapy (HAART) in Liuzhou,Guangxi Zhuang Autonomous Region (Guangxi).Methods HIV/AIDS patients receiving HAART for the first time since 1 January 2013 were selected.Data on BMI was analyzed among patients receiving HAART at baseline,6 months and 12 months after treatment.By using the general linear model repeated measures of analysis of variance,BMI dynamic variations and influencing factors were described and analyzed.Results The average BMI of 2 871 patients at baseline,6th months and 12th months appeared as (20.65 ±3.32),(20.87 ± 3.22) and (21.18 ± 3.20),respectively,with differences all statistically significant (F=18.86,P＜0.001).BMI were increasing over time with treatments (F=37.25,P＜0.001).Main influencing factors were noticed as:age,sex,marital status,baseline data of CD4+T cells and the WHO classification on clinical stages.Conclusions Higher proportion of BMI malnutrition counts was seen among patients before receiving HAART in Liuzhou.BMI of the patients that were on HAART seemed being influenced by many factors.It is necessary to select appropriate treatment protocols on different patients so as to improve the nutritional status of the patients.
