We describe a 21-year-old Italian male affected by hypokalemic tetraparesis with acute onset. In the emergency ward, the patient was agitated, with tachycardia (140/min) and systolic hypertension (180/70 mm Hg). He was not able to flex the lower extremities against a light resistance and furthermore, he was hypotonic and without tendon reflexes. One hour later he developed strength deficit of the upper extremities as well. Biochemical analyses revealed severe hypopotassemia (2.1 meg/l). After administration of 140 meq potassium phosphate, the patient began to improve, and 12 h after the onset he was able to walk normally. Successive investigations documented an undiagnosed case of Graves' disease. Thyrotoxic hypokalemic paralysis has been observed almost only in Asians, however, with this case and others reported, we believe that it should be considered as a cause of muscular paralysis also in Caucasians.
我们描述了一名21岁的意大利男性，突发低钾性四肢轻瘫。在急诊病房，患者烦躁不安，伴有心动过速（140次/分钟）和收缩期高血压（180/70 mmHg）。他无法抵抗轻微阻力屈曲下肢，此外，他肌张力减退且无腱反射。1小时后，他的上肢也出现了肌力减退。生化分析显示严重低钾血症（2.1 mmol/l）。给予140 meq磷酸钾后，患者开始好转，发病12小时后他能够正常行走。后续检查确诊为一例未诊断出的格雷夫斯病。甲状腺毒症性低钾性麻痹几乎仅在亚洲人中观察到，然而，通过该病例及其他报道，我们认为在白种人中也应将其视为肌肉麻痹的一个病因。
