ABSTRACT
Objective To explore the efficacy and side effects of highly active antiretroviral therapy (HAART) in human immunodeficiency virus (HIV)-infected patients with different CD4+ cell counts.Methods The clinical data of HIV-infected patients who accepted TDF (tenofovir disoproxil fumarate) + 3TC (lamivudine) + EFV (efavirenz) treatment were retrospectively collected in Jiangmen region.All patients were divided into group A(350/μl ≤ CD4 + ＜ 500/μ1),group B (200/μl ≤ CD4 + ＜ 350/μl) and group C(CD4+ ＜ 200/μl)according to their CD4+ cell counts.The efficacy and side effects in different groups were compared.Results A total of 132 clinical cases was collected,including 32 cases in group A,42 cases in group B,and 58 cases in group C.No statistically difference was found among three groups in terms of gender,age,or route of transmission.CD4 + cell counts after treatment was significantly higher than that before treatment in each group (P ＜ 0.05).The increase of CD4 + cell counts in groups A,B,and C was 75.6 ± 52.1,80.5 ± 58.7,and 97.5 ± 78.7 after 6-month HAART,respectively ; and 71.4 ± 58.9,110.8 ± 71.6,and 113.7 ± 88.3 after 12-month HAART,respectively.Statistical analysis showed no significant difference among three groups (P ＞ 0.05).The incidence of side effects in groups A,B,and C was 4/32,14/42,and 32/58 in 3-month HAART,respectively; and 1/32,8/42,and 22/58 in 3 ～ 12 month HAART,respectively.Statistical analysis showed significant difference among three groups (group C ＞ group B ＞ group A,P ＜ 0.05).Conclusions It was effective to begin the anti-retroviral treatment in all stages.The incidence of side effects may be less if anti-retroviral treatment began in early period.
ABSTRACT
Objective To explore the effect of anti-retroviral therapy on interleukin(IL)-7/IL-7R in human immunodeficiency virus(HIV) infected patients in China.Methods Cases were divided into 2 groups:HIV-infected group (35 cases),and control group (30 cases).IL-7 in serum,IL-7R(CD127) expression in CD4 +T cells,and CD4 +T cells count were detected and compared between two groups before and after treatment for 1 year.Results IL-7 level in the serum of HIV infected group before treatment [(8.98 ±3.77) pg/ml] was significantly higher than that in control group [(3.84 ±0.86) pg/ml] (P ＜0.05).The counts of CD4+T cells [(202.65 ± 121.54)/μl],CD4 + CD127 + T cells [(60.25 ± 11.75) ％],and CD8 + CD127 + T cells [(46.27 ± 12.10)％] in HIV-infected group were significantly lower than those in control group [(766.99 ± 103.21)/L,(76.89 ± 20.01) ％,(81.27 ± 12.35)％] (P ＜0.05).After anti-retroviral therapy (ART),IL-7 level in the serum of HIV-infected group[(5.55 ± 1.35) pg/ml]was decreased,and CD4+T cells [(450.58 ± 15)/μl],CD4 + CD127 +T cells [(69.82 ± 15.24)％],and [CD8 + CD127 + T(59.23± 14.73) ％] cells was increased in HIV-infected group,with a significant difference between two groups (P ＜0.05).Conclusions ART could improve the IL-7 level in the serum and IL-7R(CD127)expression in CD4 +T cells of HIV-infected patients.However,they still cannot become normal level.
