INTRODUCTION
Rapid scale-up of antiretroviral therapy rollout in Sub-Saharan African countries faces the challenge of virological failure. This could be the consequence of transmitted drug-resistant human immunodeficiency virus strains at the population level. While a pre-antiretroviral therapy genotypic test has been a major component of the human immunodeficiency virus management programme in developed nations, it is yet to be incorporated into the antiretroviral therapy programme in resource-poor countries.
CASE PRESENTATION
A 32-year-old Black African woman was seen for her six-month routine review. Her viral load after initiation of fixed drug combination of tenofovir, emtricitabine and efavirenz was 31,397 RNA copies/mL. Adherence was assessed to be good based on pharmacy pick-up dates, on-time clinic appointment records, medical file review, self-reporting and treatment supporter's report. Her viral load was repeated after another two months of close monitoring; the result showed viral load of 31,159 RNA copies/mL. She was assessed as virological failure to her first-line antiretrovirals and commenced on second-line antiretrovirals: zidovudine/lamivudine/Aluvia(®) (lopinavir and ritonavir). A human immunodeficiency virus drug genotypic testing showed she was only susceptible to zidovudine and protease inhibitors. At third month on the new regimen, her viral load was suppressed.
CONCLUSIONS
This case report demonstrates the possibility of a silent epidemic within the human immunodeficiency virus pandemic in resource-poor settings like Eastern Cape, South Africa. We described a case of early virological failure in a highly motivated young woman. Although, a pre-antiretroviral therapy genotypic test is yet to be incorporated into a human immunodeficiency virus programme in resource-poor countries, the need for it might become evident as the programme expands. Close monitoring of the viral load of patients according to national guidelines will enable early detection of a failing regimen and prompt intervention can be instituted to prevent morbidity and mortality. There is an urgent need to strengthen the human immunodeficiency virus programme in resource-poor countries to prevent the emergence of an epidemic of transmitted drug-resistant human immunodeficiency virus strains within the existing human immunodeficiency virus pandemic.
引言
撒哈拉以南非洲国家快速扩大抗逆转录病毒疗法的推广面临病毒学失败的挑战。这可能是人群层面传播的耐药人类免疫缺陷病毒毒株导致的结果。虽然治疗前的人类免疫缺陷病毒基因检测在发达国家一直是人类免疫缺陷病毒管理项目的主要组成部分,但在资源匮乏国家尚未纳入抗逆转录病毒疗法项目。
病例报告
一名32岁的非洲黑人女性前来进行六个月的常规复查。她在开始使用替诺福韦、恩曲他滨和依法韦仑的固定药物组合治疗后,病毒载量为每毫升31,397个RNA拷贝。根据药房取药日期、按时就诊记录、病历审查、自我报告和治疗支持者的报告,评估其依从性良好。在密切监测的另外两个月后,再次检测她的病毒载量;结果显示病毒载量为每毫升31,159个RNA拷贝。她被评估为一线抗逆转录病毒药物治疗病毒学失败,并开始使用二线抗逆转录病毒药物:齐多夫定/拉米夫定/克力芝(洛匹那韦和利托那韦)。一项人类免疫缺陷病毒药物基因检测显示,她仅对齐多夫定和蛋白酶抑制剂敏感。在新方案治疗的第三个月,她的病毒载量得到了抑制。
结论
本病例报告表明,在南非东开普等资源匮乏地区的人类免疫缺陷病毒大流行中可能存在隐匿性流行。我们描述了一名积极性很高的年轻女性早期病毒学失败的病例。虽然治疗前的人类免疫缺陷病毒基因检测在资源匮乏国家尚未纳入人类免疫缺陷病毒项目,但随着该项目的扩大,对其的需求可能会变得明显。根据国家指南密切监测患者的病毒载量将有助于早期发现治疗失败的方案,并能及时采取干预措施以预防发病和死亡。迫切需要加强资源匮乏国家的人类免疫缺陷病毒项目,以防止在现有的人类免疫缺陷病毒大流行中出现传播耐药人类免疫缺陷病毒毒株的流行。
