ABSTRACT
Objective To evaluate the effect of second-line antiretroviral treatment (ART) on human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and provide reference for subsequent HIV/AIDS treatment.Methods Two hundred and twenty-eight HIV/AIDS patients received second-line ART during January 2011 and December 2015 in Zhengzhou were included.Two hundred and forty-eight who received first-line ART during this period were randomly enrolled as control group.CD4+ T cell count and HIV RNA load before and after treatment were compared with x2 test and t test when appropriate.Results There were 228 patients (137 male and 91 female) in the second-line ART group and 248 patients (176 male and 72 female) in the control group.In second-line ART group, CD4+ T cells increased from (274±200)/μL to (476±261)/μL after an average treatment of (39.5±18.8) months.The difference was statistically significant (t=12.91, P0.05).During the treatment, the rates of immunological failure were 9.6% (22/228) in second-line ART group and 12.9% (32/248) in the control group.There was no statistical difference between two groups (x2=1.251, P>0.05).Complete viral inhibition rates were 83.3% (190/228) in second-line ART group and 88.7% (220/248) in control group with no statistical difference (x2=2.881, P>0.05).Conclusions Second-line ART regimen has equivalent treatment efficacy with first-line ART.To achieve a better outcome, second-line ART regimen should be selected as an alternative option when first-line regimen fails.Compliance is the key to guarantee the success of antiviral therapy.
ABSTRACT
Objective To investigate the HIV drug resistance among HIV/AIDS patients who had received highly active antiretroviral treatment (HAATR) in Liangshan prefecture and related factors.Methods This investigation was conducted from August to October 2010.Data on epidemiology,treatment,CD4 + T cell,viral load and drug resistance tests were collected.Results 233 (73.50％) had a viral load of ＜ 1000 copy/ml,with the median CD4+T cell count as 329 cell/μl.26 samples appeared to be drug resistant,with the rate as 8.20％.Among 84 patients with antiviral therapy failure,the overall drug resistance rate was 30.95％(26/84).While 24 (28.57％) were resistant to non-nucleoside reverse transcriptase inhibitor (NNRTI) drugs.Among nucleoside reverse transcriptase inhibitors (NRTI),7 (8.33％) were resistant.1 (1.19％) had protease inhibitor (PI)resistance mutations identified.Factors that significantly associated with drug resistance would include:being injecting drug users (A OR =3.37,95 ％ CI:1.06-10.66,P =0.0390),having had chronic diarrhea ＞1 month (AOR=8.38,95％ CI:1.87-37.69,P=0.0055),having had CD4+T cell＜200(AOR=3.48,95％CI:1.29-9.39,P=0.0139),being residents from Butuo area (AOR=17.68,95％ CI:4.97-62.86,P＜0.0001 ).When comparing with other areas,data from Butuo showed that people who carried Yi ethnicity (AOR=17.35,95％ CI:2.01-149.73,P=0.0095) and were literate (having had primary or higher levels of education) (AOR=0.18,95％ CI:0.08-0.42,P＜0.0001 ),being married or having cohabited relations (AOR=8.17,95％ CI:2.35-28.39,P=0.001 ) were found to be less adherent (AOR=0.05,95％ CI:0.02-0.13,P＜0.0001) to the treatment.Conclusion Successful antiviral outcomes were seen among those AIDS patients under treatment,in Liangshan prefecture.Resistance rates were significantly different in regions.For IDUs,enforcement on subjects including prevention on drug resistance,adherence to HAART and treatment for drug addiction should be strengthened and programs being integrated.
ABSTRACT
Objective To stndy the clinical efficacy of bicyclol treatment for chronic hepatitis B.Methods 70 cases of chronic hepatitis B patients were randomly divided into 2 groups;35 cases in test group,with bicyclol 75mg daily,and 35 cases control group,in with SNMC 150mg daily patients in the 2 groups got continuous medication for 12 weeks.levels of serum aminotransferase changes before and after treatment were observed.Results Serum aminotransferase decreased more significantly in test group(P
