The spectrum continues with diuretic-resistant ascites, where the kidneys are unable to excrete sufficient sodium to clear the fluid even with the use of diuretic medications. Most individuals with type 2 HRS have diuretic-resistant ascites before they develop deterioration in kidney function. Signs and symptoms
Both types of hepatorenal syndrome share three major components: altered liver function, abnormalities in circulation, and kidney failure. As these phenomena may not necessarily produce symptoms until late in their course, individuals with hepatorenal syndrome are typically diagnosed with the condition on the basis of altered laboratory tests. Most people who develop HRS have cirrhosis, and may have signs and symptoms of the same, which can include jaundice, altered mental status, evidence of decreased nutrition, and the presence of ascites. Specifically, the production of ascites that is resistant to the use of diuretic medications is characteristic of type 2 HRS. Oliguria, which is a decrease in urine volume, may occur as a consequence of kidney failure; however, some individuals with HRS continue to produce a normal amount of urine. As these signs and symptoms may not necessarily occur in HRS, they are not included in the major and minor criteria for making a diagnosis of this condition; instead HRS is diagnosed in an individual at risk for the condition on the basis of the results of laboratory tests, and the exclusion of other causes. Causes
Hepatorenal syndrome usually affects individuals with cirrhosis and elevated pressures in the portal vein system (termed portal hypertension).
