A 58-year-old man was admitted to our hospital. Laboratory data showed severe liver injury and that the patient was positive for immunoglobulin M anti-hepatitis A virus (HAV) antibodies. He was also complicated with severe renal dysfunction and had an extremely high level of serum hepatocyte growth factor (HGF). Therefore, he was diagnosed with severe acute liver failure with acute renal failure (ARF) caused by HAV infection. Prognosis was expected to be poor because of complications by ARF and high serum HGF. However, liver and renal functions both improved rapidly without intensive treatment, and he was subsequently discharged from our hospital on the 21st hospital day. Although complication with ARF and high levels of serum HGF are both important factors predicting poor prognosis in acute liver failure patients, the present case achieved a favorable outcome. Endogenous HGF might play an important role as a regenerative effector in injured livers and kidneys.
Core tip: Renal involvement with hepatitis B and C is well described. However, the mechanism of hepatitis A-associated acute renal failure (ARF) is uncertain. Although the prognosis of hepatitis A is generally good, complication with ARF can have a negative impact. Hepatocyte growth factor (HGF) is a predictive factor for acute liver failure. Fulminant hepatic failure patients with high serum HGF have high mortality. By contrast, HGF is also an important factor accelerating tissue regeneration of injured organs, including the liver and kidneys. Here, we describe a patient with acute hepatitis A who achieved a favorable outcome despite complications with both ARF and high serum HGF.
