Thyrotoxic periodic paralysis

中文百科

甲状腺毒性周期性麻痹症

甲状腺毒性周期性麻痹症英语:Thyrotoxic periodic paralysis,简称TTP)是一种甲状腺机能亢进(甲状腺过度活跃)下的病况,特征是病发时会有肌肉无力的症状。病发时一般还会出现低钾血症(血液中含钾量过少)。若呼吸肌无力导致呼吸衰竭或钾水平低下导致心律不整(心跳频率不规则),则患者可能有生命危险。若不接受治疗的话,实际上这种病一般是会周期性发作的。

这种病况与某些离子信道的编码基因出现基因突变有关,而离子信道负责的是电解质(如钠和钾)的跨细胞膜运送。最主要的相关信道为L型钙信道α1亚基内向整流性钾信道2.6;因此这种病被归分为离子信道疾病。相信是信道的异常导致钾在高甲状腺激素的情况下流入细胞中,此时一般还会有另一种沉淀剂。

The non-selective beta blocker propranolol can rapidly improve the symptoms of hyperthyroidism, including attacks of TPP.
Carl Friedrich Otto Westphal

Thyrotoxic periodic paralysis (TPP) is a condition featuring attacks of muscle weakness in the presence of hyperthyroidism (overactivity of the thyroid gland). Hypokalemia (a decreased potassium level in the blood) is usually present during attacks. The condition may be life-threatening if weakness of the breathing muscles leads to respiratory failure, or if the low potassium levels lead to cardiac arrhythmias (irregularities in the heart rate). If untreated, it is typically recurrent in nature.
