title: Albumin dialysis reduces portal pressure acutely in patients with severe alcoholic hepatitis.
abstract: OBJECTIVE
  In patients with alcoholic hepatitis (AH), inflammation contributes to the severity of portal hypertension. This study evaluates the acute effects of albumin dialysis, using the Molecular Adsorbents Recirculating System (MARS), on portal pressure in AH.
  
  
  METHODS
  Eleven patients with AH and portal hypertension were treated with MARS (n=8) or haemofiltration (n=3). All patients had associated organ failure manifested by hepatic encephalopathy (Grade 2 or more) or renal failure. Hepatic venous pressure gradient (HVPG) was measured before, during and after the treatment session.
  
  
  RESULTS
  A rapid significant reduction of HVPG was observed by 6 h (falling by > or =20% in 7/8 patients, reaching 12 mmHg in 6/8), which was sustained up to 18 h after stopping dialysis. Similar rapid sustained improvements of systemic haemodynamics were also observed. No changes occurred in three patients receiving haemofiltration alone.
  
  
  CONCLUSIONS
  Albumin dialysis produces clinically significant, acute reduction in portal pressure but the mechanism by which this effect is achieved is not clear. Our results suggest that MARS may be a useful adjunct in management of portal hypertension, particularly in patients with severe AH with associated organ failure.
