Glucocorticoids plus N-acetylcysteine in severe alcoholic hepatitis.

BACKGROUND: Mortality among patients with severe acute alcoholic hepatitis is high, even among those treated with glucocorticoids. We investigated whether combination therapy with glucocorticoids plus N-acetylcysteine would improve survival. METHODS: We randomly assigned 174 patients to receive prednisolone plus N-acetylcysteine (85 patients) or only prednisolone (89 patients). All patients received 4 weeks of prednisolone. The prednisolone-N-acetylcysteine group received intravenous N-acetylcysteine on day 1 (at a dose of 150, 50, and 100 mg per kilogram of body weight in 250, 500, and 1000 ml of 5% glucose solution over a period of 30 minutes, 4 hours, and 16 hours, respectively) and on days 2 through 5 (100 mg per kilogram per day in 1000 ml of 5% glucose solution). The prednisolone-only group received an infusion in 1000 ml of 5% glucose solution per day on days 1 through 5. The primary outcome was 6-month survival. Secondary outcomes included survival at 1 and 3 months, hepatitis complications, adverse events related to N-acetylcysteine use, and changes in bilirubin levels on days 7 and 14. RESULTS: Mortality was not significantly lower in the prednisolone-N-acetylcysteine group than in the prednisolone-only group at 6 months (27% vs. 38%, P = 0.07). Mortality was significantly lower at 1 month (8% vs. 24%, P = 0.006) but not at 3 months (22% vs. 34%, P = 0.06). Death due to the hepatorenal syndrome was less frequent in the prednisolone-N-acetylcysteine group than in the prednisolone-only group at 6 months (9% vs. 22%, P = 0.02). In a multivariate analysis, factors associated with 6-month survival were a younger age (P<0.001), a shorter prothrombin time (P<0.001), a lower level of bilirubin at baseline (P<0.001), and a decrease in bilirubin on day 14 (P<0.001). Infections were less frequent in the prednisolone-N-acetylcysteine group than in the prednisolone-only group (P = 0.001); other side effects were similar in the two groups. CONCLUSIONS: Although combination therapy with prednisolone plus N-acetylcysteine increased 1-month survival among patients with severe acute alcoholic hepatitis, 6-month survival, the primary outcome, was not improved.

Vascular involvement of the liver in Turner's syndrome.

Unexplained liver test abnormalities are frequent in patients with Turner's syndrome. This cohort study was performed to clarify the histopathologic features, causes, and long-term outcome of liver involvement in these patients. Thirty patients with persistently abnormal liver test results were followed-up for 8.8 +/- 5.2 years. Liver specimens were available in 27 patients. Marked architectural changes were present in 10 patients, including nodular regenerative hyperplasia in six, multiple focal nodular hyperplasia in two, and cirrhosis in two patients. These changes frequently were associated with obliterative portal venopathy lesions and with aortic malformations. There was mild to moderate portal fibrosis in 15 of the 17 other patients, inflammatory infiltrates in nine patients, and nonalcoholic fatty liver disease in 11 patients. Bile duct alterations resembling small duct sclerosing cholangitis were observed in 21 patients (with or without architectural changes). There was no viral, alcoholic, autoimmune, or drug-induced liver damage. Portal hypertension was observed in four patients with marked architectural changes, including three in whom refractory ascites or recurrent variceal bleeding developed, one of whom underwent transplantation. None of the patients without marked architectural changes experienced progressive or decompensated liver disease. There was no evidence of liver toxicity from estrogen replacement therapy. In conclusion, the main causes of liver involvement in Turner's syndrome are vascular disorders, probably of a congenital origin, and nonalcoholic fatty liver disease. In patients with vascular disorders, severe liver disease requiring liver transplantation may develop. Estrogen therapy does not appear to be pathogenically implicated.

[Primary malignant melanoma of the esophagus]. / Mélanome primitif de l'oesophage.

We report the case of primary malignant melanoma of oesophagus in a 63-year-old man who presented with a 8-week history of dysphagia. Esophagoscopy demonstrated a polypoid mass expanding in the mid-oesophagus without causing obstruction. Based on histological and immunohistochemical studies, the diagnosis of primary esophageal malignant melanoma was made. Radical resection was not possible because of regional tumour extension at the time of diagnosis. The patient underwent percutaneous endoscopic gastrostomy. Death occurred 4 months later because of acute respiratory failure.
