2000 - 2014年西班牙马德里感染艾滋病毒1型儿童和青少年的洛匹那韦-利托那韦治疗的效果

2019-04-12 不详 网络

儿童中最常用的蛋白酶抑制剂是洛匹那韦-利托那韦(LPV/r),可提供持久的病毒载量抑制,并增加CD4+ 细胞计数。该研究描述了西班牙15年内 使用LPV/r治疗的HIV-1感染儿童患者的病毒学结果。纳入HIV-1感染儿童和青少年的马德里队列中在2000-2014年期间接受LPV/r治疗的患者。记录LPV/r暴露之前(基线)和期间患者的流行病学-临床特征,病毒抑制,CD4 + T-CD8 + T细胞

儿童中最常用的蛋白酶抑制剂是洛匹那韦-利托那韦(LPV/r),可提供持久的病毒载量抑制,并增加CD4+ 细胞计数。该研究描述了西班牙15年内 使用LPV/r治疗的HIV-1感染儿童患者的病毒学结果。

纳入HIV-1感染儿童和青少年的马德里队列中在2000-2014年期间接受LPV/r治疗的患者。记录LPV/r暴露之前(基线)和期间患者的流行病学-临床特征,病毒抑制,CD4 + T-CD8 + T细胞计数的变化和药物敏感性。从2011年收集的样本中的病毒中鉴定出耐药性突变(DRM)。我们使用Stanford的HIVdb算法预测了携带DRM的19种抗逆转录病毒药物的药物敏感性。

结果显示,2000-2014期间接受LPV/r的534名患者中共有199名(37.3%)在第一组(组1),第二组(组2)或其他治疗组(组3)中。患者主要是西班牙人(81.9%),围产期感染(96.5%),B亚型病毒(65.3%)和2000年前诊断为HIV(67.8%)。首次接受LPV/r治疗的平均年龄为9.7岁。在使用蛋白酶抑制剂治疗后,第1组和第2组的病毒抑制率高于第3组。第1,2和3组患者的病毒抑制率分别为87.5%,68.6%和64.8%。LPV/r治疗期间可获得的耐药数据的64名患者中,27名(42.3%)对蛋白酶抑制剂出现DRM,28名(58.3%)对逆转录酶抑制剂出现DRM,21名(43.7%)对非逆转录酶-抑制剂出现DRM。达芦那韦/利托那韦,阿扎那韦-利托那韦和替拉那韦/利托那韦的敏感性最高,那非那韦最低。

总之,该研究结果表明,当蛋白酶抑制剂作为一线方案的一部分时,患者会有更好的淋巴细胞恢复,并且会有更多的患者达到病毒抑制。根据LPV/r-治疗-儿童队列中的DRM,用于拯救抗逆转录病毒治疗方案的抗逆转录病毒药物受损程度最低,主要是新的蛋白酶抑制剂。
