ㅍ신 기능 이상은 간경화 환자에서 중요한 문제이다. 이러한신 기능 이상은 복수 생성에 중요한 역할을 할 뿐 아니라, 간경화 환자들의 예후 인자로도 매우 중요하여 간 이식의 선별기준이 된다. 간신증후군(hepatorenal syndrome)은 순환 기능부전으로 인해 말기 간 질환에서 흔하게 발생하는 발생하는가역적인 신부전이다[1]. 간 질환의 합병증 중 가장 심한 것의 하나로 간주되며, 일반적으로 급성 간부전과 복수성 간경화 환자에서 발생한다. 병태 생리학적으로 간신증후군에서신장 기능 장애는 내인성 신장 질환이 없이 조직학적으로는정상이거나 아주 약간의 이상 소견만 관찰되며, 신장 피질의혈관 수축으로 인해 신장내 나트륨의 저류와 사구체 여과율의 감소, 핍뇨가 발생하는 것으로 이해되고 있다[2]. 일반적으로 대부분의 환자에서 이와 같은 형태의 신부전의 자연 경과는 치명적인 결과에 이르게 된다. 알부민과 바소프레신 유도체의 병합 치료, 간 이식에 의해 혈관 손상이 회복될 수있는 것으로 알려져 있다.
Abstract
Hepatorenal syndrome is a functional renal failure occurred in end-stage liver disease. It is regarded as one of the most serious complications of liver disease; commonly occur in patients with cirrhosis or acute liver failure. Pathophysiologically, portal hypertension induced vasoconstriction in the renal cortex reduces glomerular filtration rate. There are no intrinsic renal diseases or histological abnormalities. In most patients, the natural course of the renal failure leads to fatal consequences, even though various treatment options have been provided. Liver transplantation and combination therapy of albumin and vasopressin analogs can restore the damage of the blood vessel.
