Comparative Study
Infection in patients with severe alcoholic hepatitis treated with steroids: early response to therapy is the key factor.
In severe (Maddrey score >or=32) alcoholic hepatitis (AH), infection is classically viewed as a contraindication for corticosteroids, although specific data are lacking. This study's aims were (1) to evaluate the incidence of infection in patients with severe AH before and after corticosteroid treatment; (2) to determine whether infection contraindicates corticosteroids; and (3) to focus on predictive factors of development of infection. ⋯ Severe AH is associated with high risk of infection. Infection screening is warranted but should not contraindicate steroids. In terms of mechanisms, nonresponse to steroids is the key factor in development of infection and prediction of survival.

Routine laboratory tests that reflect intravascular volume status can play an important role in the early assessment of acute pancreatitis (AP). The objective of this study was to evaluate accuracy of serial blood urea nitrogen (BUN) versus serial hemoglobin (Hgb) measurement for prediction of in-hospital mortality in AP. ⋯ In a large, hospital-based cohort study, we identified serial BUN measurement as the most valuable single routine laboratory test for predicting mortality in AP.

Recommendations for patients with Barrett's esophagus (BE) include endoscopic surveillance with esophagectomy for early-stage cancer, although new technologies to ablate dysplasia and metaplasia are available. This study compares the cost utility of ablation with that of endoscopic surveillance strategies. ⋯ Endoscopic ablation could be the preferred strategy for managing patients with BE with HGD. Ablation might also be preferred in subjects with LGD or no dysplasia, but the cost effectiveness depends on the long-term effectiveness of ablation and whether surveillance endoscopy can be discontinued after successful ablation. As further postablation data become available, the optimal management strategy will be clarified.
