摘要 目的调查HIV-1感染人群抗病毒治疗后HIV-1辅助受体的利用情况。方法从安徽、河南两地选择109例接受抗病毒治疗的HIV-1感染者和45例未接受抗病毒治疗的HIV-1感染者作为研究对象,通过周围血单个核淋巴细胞(PBMCs)共培养方法,分离培养HIV-1临床毒株,利用酶联免疫吸附法检测培养上清HIV-1的P24含量,通过表达趋化因子CCR5和CXCR4的Ghost细胞系检测病毒辅助受体利用,对治疗人群中HIV-1辅助受体利用因素进行探讨,并与治疗因素进行分析讨论。结果从治疗人群中分离了45株病毒,其中22株病毒(48.89%)利用CCR5辅助受体,是R5嗜性毒株;21株病毒(46.67%)利用CXC4/CCR5辅助受体,为双嗜性(X4/R5)毒株;有2株(4.44%)仅利用CXCR4辅助受体,为x4嗜毒株。从未治疗人群中分离了109株病毒,其中96株(88.07%)利用CCR5辅助受体(R5嗜性毒株);13株(11.93%)为X4/R5双嗜性毒株。HIV-1CXC4/CCR5辅助受体利用率在两组中的差异有统计学意义(χ^2=27.30,P〈0.05)。治疗方案一(齐多夫定、去羟肌苷、奈韦拉平三联用药)治疗后HIV-1CXCA/CCR5的利用率为59.09%(13/22),治疗方案二(司他夫定、去羟肌苷、奈韦拉平三联用药)治疗后HIV-1CXCA/CCR5的利用率为43.48%(10/23),二者对HIV-1辅助受体利用的影响差异没有统计学意义(χ^2=1.10,P=0.30)。结论在HIV-1感染者中,接受抗病毒治疗人群中HIV-1CXCR4/CCR5利用率高于未治疗人群。 Objective To investigate HIV-1 co-receptor usage in patients experienced anti-retroviral therapy (ART) in Anhui and Henan province of China. Methods A total of 45 HIV-1 infected individuals who have experienced ART and I09 un-experienced ART patients from Anhui and Henan province,which were called as treatment group and treatment-negative group, were selected as study subjects. HIV-1 strains were isolated from peripheral blood mononuclear cells of whole blood from patients. HIV-1 p24 in the culture supernatant was measured using a commercial enzyme-linked immunosorbent assay(ELISA) kit. HIV-I co- receptor usage was identified using Ghost cell lines expressing CD4 and the chemokine receptor CCR5 or CXCR4. Results Among 45 HIV strains from the treatment group,22 (48.9%) strains used CCR5 as a co- receptor (R5 tropic strain),21 (46. 7% ) strains used CXCR4/CCR5 as a co-receptor (X4/R5 duel tropic strain) ,and 2(4. 4% ) used only CXCR4 as a co-receptor(X4 tropic strain). In 109 strains from treatment- negative group,96 (88. 1% ) strains used CCR5 as a co-receptor(R5 tropic strain),13( 11.9% ) strains used CCRS/CXCR4 as a co-receptor use (X4/R5 strain ). A significant difference was found between two groups in X4 co-receptor usages(χ^2= 27.30, P 〈 0. 05 ). Furlhermore, after treated with AZT + DDI + NVP, the HIV-l CXC4/CCR5 utilization was 59. 09% ( 13/22), meanwhile after treated with D4T + DDI + NVP, the HIV-1 CXCA/CCR5 utilization was 43.48% (10/23),which the difference was not statistical significant ( χ^2 = 1. 10, P = O. 30). Conclusion HIV-1 CXCRd/CCR5 co-receptor utilization was higher in ART patients than treatment-negative patients.
