Little clinical data support specific recommendations for the amount of nutritional support. The American College of Gastroenterology (ACG) recommends 35 calories/kg to 40 calories/kg of body weight per day and a protein intake of 1.2 g/kg to 1.5g/kg per day.5 In an average, 70-kg patient, this is 2,450 to 2,800 calories a day. For patients who are not able to meet these nutritional needs by mouth, enteral feeding with a small-bore (Dobhoff) feeding tube can be used, even in patients with known esophageal varices.
Most of these patients have anorexia and nausea and do not meet these caloric recommendations by eating. Nutritional support is a low-risk intervention that can be provided on almost all inpatient medical care areas. Hospitalists should be attentive to nutritional support early in the hospitalization of these patients.
Corticosteroid therapy is recommended by the ACG for patients with alcoholic hepatitis and a Maddrey’s discriminant function greater than 32.5 There is much debate about this recommendation, as conflicting data about efficacy exist.

A 2008 Cochrane review included clinical trials published before July 2007 that examined corticosteroid use in patients with alcoholic hepatitis. A total of 15 trials with 721 randomized patients were included. The review concluded that corticosteroids did not statistically reduce mortality compared with placebo or no intervention; however, mortality was reduced in the subgroup of patients with Maddrey’s scores greater than 32 and hepatic encephalopathy.6 The review concluded that current evidence does not support the use of corticosteroids in alcoholic hepatitis, and more randomized trials were needed.
Another meta-analysis demonstrated a mortality benefit when the largest studies, which included 221 patients with high Maddrey’s scores, were analyzed separately.7 Contraindications to corticosteroid treatment include active infection, gastrointestinal bleeding, acute pancreatitis, and renal failure. Other concerns about corticosteroids include potential adverse reactions (hyperglycemia) and increased risk of infection. Prednisolone is preferred over prednisone because it is the active drug. The recommended dosage is 40 mg/day for 28 days followed by a taper (20 mg/day for one week, then 10 mg/day for one week).
Some data suggest that if patients on corticosteroid therapy do not demonstrate a decrease in their bilirubin levels by Day 7, they are at higher risk of developing infections, have a poorer prognosis, and that corticosteroid therapy should be stopped.8 Some experts use the Lille model to decide whether to continue corticosteroids. In one study, patients who did not respond to prednisolone did not improve when switched to pentoxifyline.9
Patients discharged on corticosteroids require very careful coordination with outpatient providers as prolonged corticosteroid treatment courses can lead to serious complications and death. Critics of corticosteroid therapy in these patients often cite problems related to prolonged steroid use, especially in patients who do not respond to therapy.10
Pentoxifylline, an oral phosphodiesterase inhibitor, is recommended by the ACG, especially if corticosteroids are contraindicated.5 In 2008, 101 patients with alcoholic hepatitis were enrolled in a double-blind, placebo-controlled trial comparing pentoxifylline and placebo. This study demonstrated that patients who received pentoxifylline had decreased 28-day mortality (24.6% versus 46% receiving placebo). Of those patients who died during the study, only 50% (versus 91% in the placebo group) developed hepatorenal syndrome.11 However, a Cochrane review of all studies with pentoxifylline concluded that no firm conclusions could be drawn.12
