Fulminant hepatic failure following overdose of the vitamin A metabolite acitretin.

Hepatotoxicity associated with the therapeutic ingestion of the vitamin A metabolite acitretin is well recognized. No reported cases of hepatic dysfunction as a consequence of acitretin overdose are, however, present. Here for the first time we report a case of fulminant hepatic failure following an intentional overdose of 600 mg of acitretin. The patient fulfilled the King's College Hospital poor prognostic criteria by 66 h after overdose, but demonstrated a rapid improvement thereafter and did not require liver transplantation. Given the known association between psoriasis and depression, and the possible association of acitretin with psychiatric illness, this is an important potential adverse event.

Primary prophylaxis of variceal hemorrhage: a randomized controlled trial comparing band ligation, propranolol, and isosorbide mononitrate.

BACKGROUND & AIMS: This randomized controlled trial compared variceal band ligation (VBL), propranolol (PPL), and isosorbide-5-mononitrate (ISMN) in the prevention of first esophageal variceal bleed. METHODS: Over a 6-year period, 172 patients with cirrhosis, grade II or III esophageal varices that had never bled, were recruited; 44 into VBL, 66 into PPL, and 62 into ISMN. Baseline patient characteristics: age, 55 +/- 11 years; Child-Pugh score, 8 +/- 2; 65% alcohol-induced cirrhosis; follow-up period, 19.7 +/- 17.6 months (range, 0.13-72.1 months), were comparable in the 3 groups. RESULTS: On intention-to-treat analysis, variceal bleeding occurred in 7% of patients randomized to VBL, 14% to PPL, and 23% to ISMN. The 2-year actuarial risks for first variceal bleed were 6.2% (95% confidence interval [CI], 0.0%-15.0%) for VBL, 19.4% (95% CI, 0.1%-32.4%) for PPL, and 27.7% (95% CI, 14.2%-41.2%) for ISMN. A significant number of patients reported side effects with drug treatment (45% PPL and 42% ISMN vs. 2% VBL; P = 0.00), resulting in withdrawal from treatment in 30% of PPL and 21% of ISMN patients. There were no statistically significant differences in mortality rates in the 3 groups. In as-treated analysis, there was a statistically significant difference in actuarial risk for bleeding at 2 years between VBL and ISMN (7.5%, 95% CI, 2.5%-10.6% vs. 33.0%, 95% CI, 15%-49%, respectively, log rank test P = 0.03) but not between VBL and PPL. CONCLUSIONS: VBL was equivalent to PPL and superior to ISMN in preventing first variceal bleed. The side-effect profile for pharmacotherapy was considerable.
