초록

Terlipressin은 vasopressin 유사약제이지만 그에 비해 부작용이 적게 발생하여 안전하게 사용되는 혈관수축제로 간경변에서의 정맥류 출혈이나 간신증후군 치료에 일차적으로 사용되고 있다. Terlipressin은 vasopressin과 다르게 V2 수용체보다 V1 수용체에 주로 작용하기 때문에 V2 수용체와 관련된 항이뇨 작용이나 나트륨뇨 배설항진이 거의 일어나지 않는다고 알려졌다. 그러나 실제 임상에서 terlipressin에 의해 SIAD가 발생하고 그로 인해 저나트륨혈증이 생긴 예가 다양하게 보고되고 있다. 본 증례에서는 terlipressin 투여로 인해 SIAD가 발생한 것으로 생각되며 그 결과 중증의 저나트륨혈증과 그로 인한 경련발작을 일으켰으나 terlipressin을 중단하고 수분 섭취를 제한하는 등의 SIAD에 준한 치료 후에 증상이 모두 호전된 예를 경험하였기에 이를 문헌고찰과 함께 보고하는 바이다.

Terlipressin has splanchnic vasoconstrictive effects, and is generally used for the management of gastroesophageal variceal bleeding secondary to liver cirrhosis. Terlipressin is a synthetic arginine vasopressin (AVP) analog containing a nonapeptide sequence. Terlipressin has increased selectivity for the V1 receptor, compared with AVP; hence, it is considered to be a safe vasoconstrictor. However, side effects such as hyponatremia and seizure, although very rare, have been reported. Hyponatremia related to terlipressin may be caused by the syndrome of inappropriate antidiuresis (SIAD), which is a disorder of sodium and water balance characterized by hypotonic hyponatremia without elevation of the antidiuretic hormone level. Here, we report a case of hyponatremic seizure induced by an infusion of terlipressin in a 52-year-old female who had isolated gastric variceal bleeding secondary to alcoholic liver cirrhosis.
