Four patients with rheumatoid arthritis (R.A.) developed myasthenia gravis after taking penicillamine. In one patient withdrawal of the drug was followed by spontaneous remission of the myasthenia, and in two the dose of anticholinesterase was subsequently reduced. In the fourth patient continuing penicillamine treatment was associated with increasingly severe myasthenic features, but on withdrawal of the drug these resolved. As myasthenia gravis rarely complicates R.A. its onset in these patients shortly after the start of penicillamine treatment suggested that penicillamine may have precipitated this condition.
四名类风湿性关节炎(R.A.)患者在服用青霉胺后患上了重症肌无力。其中一名患者停药后重症肌无力自发缓解,另外两名患者随后抗胆碱酯酶药物剂量减少。第四名患者继续使用青霉胺治疗时,重症肌无力症状日益严重,但停药后症状消失。由于重症肌无力很少并发类风湿性关节炎,这些患者在开始服用青霉胺后不久就出现这种疾病,提示青霉胺可能诱发了该病。
