Human leukocyte antigen B (HLA-B) is responsible for presenting peptides to immune cells and plays a critical role in normal immune recognition of pathogens. A variant allele, HLA-B*57:01, is associated with increased risk of a hypersensitivity reaction to the anti-HIV drug abacavir. In the absence of genetic prescreening, hypersensitivity affects ~6% of patients and can be life-threatening with repeated dosing. We provide recommendations (updated periodically at http://www.pharmkgb.org) for the use of abacavir based on HLA-B genotype.
人类白细胞抗原 B(HLA-B)负责向免疫细胞呈递肽,在正常的病原体免疫识别中发挥关键作用。一个变异等位基因 HLA-B*57:01 与对 HIV 药物阿巴卡韦产生过敏反应的风险增加有关。在没有遗传预筛选的情况下,过敏反应影响约 6%的患者,并且随着重复给药可能会危及生命。我们根据 HLA-B 基因型提供了使用阿巴卡韦的建议(定期在 http://www.pharmkgb.org 更新)。
