We aimed to investigate potential associations between human leukocyte antigen (HLA) class I and class II alleles and the development of anaphylactic/anaphylactoid reactions in patients with multiple sclerosis (MS) treated with natalizumab.
HLA class I and II genotyping was performed in patients with MS who experienced anaphylactic/anaphylactoid reactions and in patients who did not develop infusion-related allergic reactions following natalizumab administration.
A total of 119 patients with MS from 3 different cohorts were included in the study: 54 with natalizumab-related anaphylactic/anaphylactoid reactions and 65 without allergic reactions. HLA-DRB113 and HLA-DRB114 alleles were significantly increased in patients who developed anaphylactic/anaphylactoid reactions (p M-H = 3 × 10(-7); odds ratio [OR]M-H = 8.96, 95% confidence interval [CI] = 3.40-23.64), with a positive predictive value (PPV) of 82%. In contrast, the HLA-DRB1*15 allele was significantly more represented in patients who did not develop anaphylactic/anaphylactoid reactions to natalizumab (p M-H = 6 × 10(-4); ORM-H = 0.2, 95% CI = 0.08-0.50), with a PPV of 81%.
HLA-DRB1 genotyping before natalizumab treatment may help neurologists to identify patients with MS at risk for developing serious systemic hypersensitivity reactions associated with natalizumab administration.
我们旨在研究人类白细胞抗原(HLA)I 类和 II 类等位基因与接受那他珠单抗治疗的多发性硬化症(MS)患者发生过敏/过敏样反应的潜在相关性。
对发生过敏/过敏样反应的 MS 患者和接受那他珠单抗治疗后未发生输注相关过敏反应的患者进行 HLA I 类和 II 类基因分型。
本研究共纳入了来自 3 个不同队列的 119 名 MS 患者:54 名患者发生了那他珠单抗相关的过敏/过敏样反应,65 名患者未发生过敏反应。发生过敏/过敏样反应的患者 HLA-DRB113 和 HLA-DRB114 等位基因明显增加(p M-H = 3×10(-7);优势比[OR]M-H = 8.96,95%置信区间[CI] = 3.40-23.64),阳性预测值(PPV)为 82%。相反,未发生那他珠单抗过敏/过敏样反应的患者 HLA-DRB1*15 等位基因明显更为多见(p M-H = 6×10(-4);OR M-H = 0.2,95%CI = 0.08-0.50),PPV 为 81%。
在开始那他珠单抗治疗之前进行 HLA-DRB1 基因分型可能有助于神经科医生识别出具有发生与那他珠单抗给药相关的严重全身性过敏反应风险的 MS 患者。
