Bromfenac sodium (Duract) is a phenylacetic acid-derived nonsteroidal anti-inflammatory agent introduced in the United States in 1997 and withdrawn in 1998. We describe the first case of fulminant hepatic failure associated with this agent treated successfully with liver transplantation. Similarities to hepatotoxicity with related agents is discussed.

Barrett's epithelium is a recognized premalignant condition for esophageal adenocarcinoma. Nonsteroidal antiinflammatory drugs (NSAIDs) decrease the relative risk of colon cancer in humans and the esophageal tumor load in carcinogen-treated mice. Previous studies provided conflicting results for COX-2 activity in Barrett's mucosa. Pinch mucosal biopsies were collected from Barrett's and adjacent normal esophageal mucosa from 17 patients with Barrett's esophagus. Low-grade dysplasia was found in seven patients. COX-2 protein was undetectable in normal esophageal mucosa. COX-1 protein expression did not vary between normal and Barrett's epithelium. Increased COX-2 protein was detected in Barrett's epithelium in seven patients (41%) but did not differ with or without dysplasia (43% vs 40%). In conclusion, COX-2 protein is increased in 41% of patients with Barrett's epithelium compared to normal esophageal mucosa but did not differ with or without dysplasia. COX-2 induction may be an early event in the development of Barrett's esophagus.
