RESUMEN
Objective To compare the rates of regimen modification between patients with different initial antiretroviral therapy, and to investigate risk factors associated with drug toxicity-related regimen modification.Methods A two-years retrospective cohort study was conducted in 14 060 patients who initiated antiretroviral treatment with Zidovudine (AZT)/Tenofovir disoproxil (TDF)+Lamivudine (3TC)+Efavirenz (EFV) since 2012.There were 5 126 patients initiated TDF+3TC+EFV therapy (TDF group) and 8 934 patients initiated AZT+3TC+EFV therapy (AZT group).Chi-square test was used to compare the rate of first-line regimen modification and the rate of toxicity-related regimen modification between two groups.Cox proportional hazard model was used to investigate the risk factors associated with regimen modification.Results A total of 14 060 acquired immunodeficiency syndrome patients were observed for a median period of 1.85 person-years.There were 2 795 patients who changed their initial antiretroviral regimen and the rate of initial regimen modification was 19.9%.Two hundred patients who changed their initial regimen due to pregnancy were excluded.There were 2 070 patients in AZT group who changed their initial regimen with a rate of 23.5%.Among them, 1 652 patients changed their regimen due to drug toxicity and the rate was 18.8%.There were 525 patients in TDF group who changed their initial regimen with a rate of 10.4% and the rate of toxicity-related regimen modification was 6.2%.The differences between two groups were statistical significance (χ2=366.68 and 416.89, respectively, both P45 years old, BMI<18.5 kg/cm2 and baseline CD4+ T cell count<200/mL were risk factors associated with regimen modification.
RESUMEN
Objective To compare the differences of CD4 +T lymphocyte (CD4) counts between patients aged 18 and over,to explore the effect of age on treatment,36 months after having received the China National Free AIDS Antiretroviral Treatment on HIV/AIDS.Methods Through the National ART Information Ssystem,we selected those HIV/AIDS patients who initiated the ART 36 months after the ART,between January 1,2010 and December 31,2012 in Guangzhou,Liuzhou and Kunming.Patients were divided into age groups as 18-49,50-59 and 60 or over year olds,at the baseline of treatment.Under different levels of baseline CD4 counts,we chose the baseline and different time-point of CD4 counts as dependent variables,applied mixed linear model to analyze the effects of age,viral suppression,gender,baseline CD4/CDs ratio and initial treatment regimen.Results A total of 5 331 HIV/AIDS patients were recruited.No differences were found on age group ratios between different levels of baseline CD4 counts.At the level of baseline CD4＜200 cells/μl,both the 50-59 and 60 or above years old groups had lower CD4 counts than the 18-49 year-old group,within 36 months after the initiation of ART.However,at the baseline CD4 level of 200-350 cells/μl,no signiftcant differences on CD4 counts between the 50-59 year-old and 18-49 year-old groups were noticed.CD4 counts seemed lower in the 60 and above year-old group than in the 18-49 year-old group.Conclusion Age might serve as an influencing factor on CD4 counts within 36 months after the initiation of ART,suggesting that earlier initiation of ART might be of help to the recovery of immune function in the 50-59 year-old group.

RESUMEN
Objective To investigate the prevalence of malnutrition in human immunodeficiency virus ( HIV )‐infected children in China , and to explore and analyze the factors associated with malnutrition .Methods A cross‐sectional study was conducted by the antiretroviral treatment database of children .HIV‐infected children aged between 0 - 15 years old who initiated antiretroviral treatment were collected between January 1st , 2010 and December 31st , 2014 . Z‐score of height and weight were calculated by WHO Anthro (plus) software .Univariate and multivariate Logistic model analyses were performed to determine the factors associated with acute /chronic/mixed malnutrition .Results Baseline data of the 3 138 HIV‐infected children showed that 1 645 patients (52 .42% ) had malnutrition before antiretroviral treatment ,with acute ,chronic and mixed malnutrition of 8 .76% (275) ,39 .77% (1 248) and 3 .89% (122) ,respectively according to the type of malnutrition .Multivariate analysis showed that baseline CD4 + cell count < 200 cells/μL was the risk factor associated with acute malnutrition (aOR =2 .27 ,95% CI :1 .68 - 3 .06) ;rural settings (aOR = 1 .30 ,95% CI :1 .11 - 1 .53) ,baseline CD4 + cell count < 200 cells/μL (aOR = 1 .98 ,95% CI :1 .65 - 2 .38) ,baseline CD4 + cell count between 200 to 350 cells/μL (aOR = 1 .38 ,95% CI :1 .13 - 1 .69) and having AIDS‐related diseases (aOR = 1 .34 ,95%CI :1 .13 - 1 .59) were risk factors associated with chronic malnutrition ;and age of 11 - 15 years (aOR =2 .38 ,95% CI :1 .46 - 3 .88) ,baseline CD4 + cell count < 200 cells/μL (aOR = 4 .99 ,95% CI :3 .04 -8 .21) and having AIDS‐related diseases (aOR = 2 .45 ,95% CI :1 .65 - 3 .66) were risk factors associated with mixed malnutrition .Conclusions The prevalence of malnutrition in untreated HIV‐infected children remains high .All three types of malnutrition are associated with immunodeficiency .Early diagnosis and early treatment should be improved in HIV‐infected children through antiviral therapy to reduce the destruction of HIV to immune system .At the same time ,intensified monitoring of the nutritional status and nourishing undernourished children should be strengthened to reduce the prevalence of malnutrition .
RESUMEN
Objective To observe the analgesic effects of dexmedetomidine combined with dif-ferent-doses of sufentanil in patients undergoing spine surgery.Methods Sixty patients(ASA grade Ⅰor Ⅱ degree,age 18-70 years)undergoing spine surgery were randomly assigned into three groups ac-cording to PCA formulation(n =20):3 μg/kg sufentanil group (group S1),1.5 μg/kg dexmedetomi-dine+ 2 μg/kg sufentanil group (group S2 )and 1.5 μg/kg dexmedetomidine + 1 μg/kg sufentanil group (group S3).The same anesthesia method was applied among three groups.Patient-controlled intravenous analgesia pump was applied before 30 minutes prior to the end of surgery.The drugs in each group were diluted to 1 50 ml and infused by a pump at a rate of 3 ml/h with a patient-controlled analgesia (PCA)bolus of 0.5 ml and lock time of 30 minutes.VAS and Ramsay scores at 2 h(T0 ),4 h (T1 ),8 h(T2 ),12 h(T3 ),24 h(T4 )and 48 h(T5 )after surgery were estimated.Postoperative nausea and vomiting,bradyrhythmia and hypersomnia were also recorded.Results Compared with group S1, VAS of groups S2 and S3 was significantly decreased at T1-T5 (P <0.05).There were also no signifi-cant difference in the incidence of postoperative nausea and vomiting,bradyrhythmia and hypersomnia among three groups.Conclusion Dexmedetomidine of 1.5 μg/kg can significantly reduce the dosage of sufentanil on postoperative analgesia in patients undergoing spine surgery,and decrease the rate of postoperative nausea and vomiting without any bradyrhythmia and hypersomnia.
RESUMEN
Objective To analyze the progress and characteristics of China' s "Free AIDS treatment strategy" since the implementation of the national "four free and one care" policy against AIDS 12 years ago.Methods Retrospective cohort study and cross-sectional analysis had been conducted in this study.368 449 cases that had received the ‘free antiviral therapy’ from 2002 to 2014 were selected from the National Treatment Database.Data from the baseline (initial time of ART,CD4 cell count,and antiretroviral regimen) and from the follow-up program (dates and status of follow-up,CD4 cell counts) were gathered and analysed by SAS 9.3.Results The number of cases that having received new treatment was increasing year by year,accounting for 75.4％ of all the cases identified from 2010 to 2014.Constituent ratios of patients with baseline CD4 cell count ＜200 cells/μl and clinical diagnosis of AIDS were decreasing from 81.0％ in 2006 to 39.7 ％ in 2014.Status on drug optimization showed that:3TC replaced DDI,EFV replaced NVP and TDF replaced D4T,making the utilization rates as 99.5％,75.7％,and 60.6％,respectively,by 2014.Regions that were covered by the treatment accounted for 75.4％ of all the counties/districts involved.The previous CDC-led AIDS treatment program and mode of management had been transferred to the hospital-based model.Proportion on the twice-CD4-testing model had been 75.2％ since 2010,with the rate of virological detection increased from 70.8％ in 2010 to 87.4％ in 2014 and the virological unsuccessful testing rate decreased from 17.6％ in 2010 to 11.8％ in 2014.Among all the patients,the 1,5 and 10 year survival rates appeared as 92.2％,80.5％ and 69.6％,respectively.For patients with baseline CD4 cell counts as ＜50 cells/μl or ＞350 cells/μl,the corresponding survival rates showed as 81.6％,69.9％,60.9％ and 97.9％,89.8％,81.0％,respectively.Conclusion China's HIV/AIDS free anti-retroviral therapy program appeared as a national treatment cohort which involved large number of participants,with new patients joining in,annually.Criterion on drug optimization and treatment were consistently following the recommendation and guidelines set by WHO.Management program on treatment had gradually turned to hospital-based,with follow-up and laboratory testing programs guaranteed,ended up with satisfactory treatment effects.
