There are about 2.1 million children infected with HIV globally and about 120,000 deaths annually. Nigeria has one of the highest rates of pediatric HIV infection globally. Pretreatment HIV drug resistance data inform the choice of first- and second-line antiretroviral therapy (ART) regimens. This study investigated the prevalence of HIV drug-resistant strains among ART-naive children in Ibadan, Nigeria. A total of 20 children aged <15 years were enrolled. Demographic, clinical, and laboratory data were documented. Total nucleic acid was extracted from blood samples after which amplification of HIV-1 pol gene was done using polymerase chain reaction. Amplified gene was sequenced using big dye sequencing method. The sequenced HIV-1 pol gene was typed and analyzed for identification of mutations indicative of drug resistance across the different classes of ART. HIV-1 RNA pol gene was successfully amplified in 12/20 (60%) children. All were identified as HIV-1 and the subtypes were G and CRF 02AG, recombinant of 02_AG/G and recombinant of 02_AG/A1. Drug-resistant mutations (DRMs) were identified in 4/12 (33%). Three out of the four mutations were identified as non-nucleoside reverse transcriptase inhibitors DRM (K103N), whereas the fourth had nucleoside reverse transcriptase inhibitors DRM (M184V). Results from this preliminary study show that drug resistance among ART-naive children is a problem in Ibadan. Pretreatment drug resistance testing is desirable in children before initiation of ART to guide effective treatment.

尼日利亚伊巴丹 HIV 感染儿童预处理耐药性监测

全球约有 210 万儿童感染 HIV,每年约有 120,000 人死亡。尼日利亚是全球儿童艾滋病毒感染率最高的国家之一。预处理 HIV 耐药性数据为一线和二线抗逆转录病毒治疗 (ART) 方案的选择提供依据。本研究调查了尼日利亚伊巴丹未接受过抗逆转录病毒治疗的儿童中 HIV 耐药菌株的流行情况。共有20名年龄<15岁的儿童参加。记录了人口统计学、临床和实验室数据。从血样中提取总核酸,然后使用聚合酶链式反应扩增 HIV-1 pol 基因。使用大染料测序方法对扩增的基因进行测序。对测序后的 HIV-1 pol 基因进行分型和分析,以识别表明不同类别 ART 耐药性的突变。HIV-1 RNA pol 基因在 12/20 (60%) 儿童中成功扩增。均被鉴定为HIV-1,亚型为G和CRF 02AG、02_AG/G重组体和02_AG/A1重组体。在 4/12 (33%) 中发现了耐药突变 (DRM)。四个突变中的三个被鉴定为非核苷逆转录酶抑制剂 DRM (K103N),而第四个具有核苷逆转录酶抑制剂 DRM (M184V)。这项初步研究的结果表明,在伊巴丹,未接受过抗逆转录病毒治疗的儿童的耐药性是一个问题。在开始 ART 之前,需要对儿童进行预处理耐药性测试,以指导有效治疗。HIV-1 RNA pol 基因在 12/20 (60%) 儿童中成功扩增。均被鉴定为HIV-1,亚型为G和CRF 02AG、02_AG/G重组体和02_AG/A1重组体。在 4/12 (33%) 中发现了耐药突变 (DRM)。四个突变中的三个被鉴定为非核苷逆转录酶抑制剂 DRM (K103N),而第四个具有核苷逆转录酶抑制剂 DRM (M184V)。这项初步研究的结果表明,在伊巴丹,未接受过抗逆转录病毒治疗的儿童的耐药性是一个问题。在开始 ART 之前,需要对儿童进行预处理耐药性测试,以指导有效治疗。HIV-1 RNA pol 基因在 12/20 (60%) 儿童中成功扩增。均被鉴定为HIV-1,亚型为G和CRF 02AG、02_AG/G重组体和02_AG/A1重组体。在 4/12 (33%) 中发现了耐药突变 (DRM)。四个突变中的三个被鉴定为非核苷逆转录酶抑制剂 DRM (K103N),而第四个具有核苷逆转录酶抑制剂 DRM (M184V)。这项初步研究的结果表明,在伊巴丹,未接受过抗逆转录病毒治疗的儿童的耐药性是一个问题。在开始 ART 之前,需要对儿童进行预处理耐药性测试,以指导有效治疗。在 4/12 (33%) 中发现了耐药突变 (DRM)。四个突变中的三个被鉴定为非核苷逆转录酶抑制剂 DRM (K103N),而第四个具有核苷逆转录酶抑制剂 DRM (M184V)。这项初步研究的结果表明,在伊巴丹,未接受过抗逆转录病毒治疗的儿童的耐药性是一个问题。在开始 ART 之前,需要对儿童进行预处理耐药性测试,以指导有效治疗。在 4/12 (33%) 中发现了耐药突变 (DRM)。四个突变中的三个被鉴定为非核苷逆转录酶抑制剂 DRM (K103N),而第四个具有核苷逆转录酶抑制剂 DRM (M184V)。这项初步研究的结果表明,在伊巴丹,未接受过抗逆转录病毒治疗的儿童的耐药性是一个问题。在开始 ART 之前,需要对儿童进行预处理耐药性测试,以指导有效治疗。
