Renal failure is common in patients who are dying from end-stage cirrhosis,
developing in 40-80% of all patients. Where there is no anatomical or path
ological cause for the renal failure, it is termed the hepatorenal syndrome
. When the hepatorenal syndrome develops, it will only recover when there i
s some degree of improvement in liver function. Thus for most patients this
will occur only after liver transplantation, although the transplantation
mortality is increased in this group. Hepatorenal syndrome is a common comp
lication of alcoholic hepatitis, and this group is unusual in that with tim
e and abstinence, significant recovery of liver function may occur. There i
s therefore a need for supportive therapy to allow time for some recovery o
f liver function in patients with alcoholic hepatitis and hepatorenal syndr
ome. Similarly, patients may need support whilst waiting for liver transpla
ntation. This article reviews the pathophysiology and treatment of hepatore
nal syndrome.
