Study Notes
Hepatorenal Syndrome (HRS)
- HRS is considered a functional type of renal impairment, meaning it is reversible and not caused by structural damage to the kidneys.
Causes and Risk Factors
- The primary cause of HRS is a complication of advanced liver disease, typically cirrhosis.
- Risk factors for developing HRS include advanced liver disease, cirrhosis, ascites, and bacterial infections.
- HRS is often associated with decompensated liver cirrhosis.
Types of HRS
- There are two types of HRS: Type 1 and Type 2.
- Type 1 HRS has a more rapid and severe course, leading to a rapid deterioration of kidney function.
- Type 2 HRS has a more indolent course, with a slower progression of kidney disease.
Characteristics and Pathophysiology
- HRS results from a combination of factors, including splanchnic vasodilation, decreased effective arterial blood volume, and increased renal vasoconstriction.
- The main characteristic of HRS is a marked impairment of renal function, often in the absence of structural kidney damage.
- HRS can lead to a mortality rate of up to 80% in patients with Type 1 HRS.
Improving Outcomes
- Early diagnosis and treatment are crucial to improve outcomes in HRS.
- Treatment typically involves managing the underlying liver disease, as well as providing supportive care to improve renal function.
