Antibodies to the acetylcholine receptor and HLA antigens have been studied in patients with myasthenia gravis occurring in association with penicillamine treatment. The properties of the antiacetylcholine receptor in these patients differed from those in patients with idiopathic myasthenia gravis in terms of specificity and affinity. These patients had an increased prevalence of HLA Bw35 and DR1 compared to controls and a decreased frequency of B8 and DR3 compared to patients with idiopathic myasthenia gravis. Likewise, they had a decreased frequency of DR4 compared to patients with rheumatoid arthritis. These data provide supportive evidence for a role for penicillamine in the induction of myasthenia gravis in genetically predisposed individuals.
对与青霉胺治疗相关的重症肌无力患者,已开展了针对乙酰胆碱受体和HLA抗原的抗体研究。这些患者体内抗乙酰胆碱受体的特性在特异性和亲和力方面与特发性重症肌无力患者不同。与对照组相比,这些患者中HLA Bw35和DR1的患病率增加;与特发性重症肌无力患者相比,B8和DR3的频率降低。同样,与类风湿关节炎患者相比,他们DR4的频率降低。这些数据为青霉胺在遗传易感性个体中诱发重症肌无力所起的作用提供了支持性证据。
