S-adenosylmethionine in alcoholic liver cirrhosis: a randomized, placebo-controlled, double-blind, multicenter clinical trial.

BACKGROUND/AIM: The efficacy of S-adenosylmethionine (AdoMet) in the treatment of liver cell injury has been demonstrated in several experimental models. The aim of this study was to investigate the effects of AdoMet treatment in human alcoholic liver cirrhosis. METHODS: A randomized, double-blind trial was performed in 123 patients treated with AdoMet (1200 mg/day, orally) or placebo for 2 years. All patients had alcoholic cirrhosis, and histologic confirmation of the diagnosis was available in 84% of the cases. Seventy-five patients were in Child class A, 40 in class B, and 8 in class C. Sixty-two patients received AdoMet and 61 received placebo. RESULTS: At inclusion into the trial no significant differences were observed between the two groups with respect to sex, age, previous episodes of major complications of cirrhosis, Child classification and liver function tests. The overall mortality/liver transplantation at the end of the trial decreased from 30% in the placebo group to 16% in the AdoMet group, although the difference was not statistically significant (p = 0.077). When patients in Child C class were excluded from the analysis, the overall mortality/liver transplantation was significantly greater in the placebo group than in the AdoMet group (29% vs. 12%, p = 0.025), and differences between the two groups in the 2-year survival curves (defined as the time to death or liver transplantation) were also statistically significant (p = 0.046). CONCLUSIONS: The present results indicate that long-term treatment with AdoMet may improve survival or delay liver transplantation in patients with alcoholic liver cirrhosis, especially in those with less advanced liver disease.

The value of Hughes-Cardiff classification in the management of perianal Crohn's disease.

PURPOSE: The aim of this study was to assess the value of Hughes' pathogenic classification in the prognosis and management of perianal Crohn's disease (CD). PATIENTS AND METHODS: This classification differentiates between purely inflammatory lesions and their mechanical or septic complications, and defines the presence of ulceration (U), fistula (F) and stricture (S), which are assigned a score of 0, 1 or 2 according to the severity and associated conditions, proximal intestinal involvement and disease activity (A, P and D). Of a series of 96 patients with CD, 12 underwent 16 procedures involving anesthesia to treat symptomatic anal lesions. Patients presenting with severe pain were explored and treated by surgical drainage or, in cases in which there was no demonstrable sepsis, by gentle dilation or infiltration with steroids. For superficial, non-specific fistulas, conventional fistulotomy was performed, and long-term seton drainage was implanted for complex fistulas. Strictures were treated by gentle dilation. Uncontrolled sepsis or proctocolitis was managed by proximal stoma creation or proctocolectomy. RESULTS: The association of cavitating ulcers (U2) and contiguous active rectal involvement (P1) was a contraindication for rectal preservation, making proctectomy or stoma creation the most feasible therapeutic option. The etiology of most, but not all, complex fistulas (F2) was the progressive cavitation of U2, whilst F1 was either of cryptoglandular origin or the result of epithelialized fissures (U1). The treatment was also adjusted to this association, and it was confirmed that most of the severe lesions (F2) and S2) were secondary to U2. CONCLUSIONS: Hughes' pathogenic classification: 1) makes it possible to set up an easily stored registry of anal and perianal Crohn's disease; 2) identifies predefined lesions, allowing the individualization of therapeutic procedures and the comparison of results, and 3) provides prognostic information.

Laparoscopy in fever of unknown origin - study of seventy cases.

Laparoscopy was performed on 70 patients with FUO after clinical review and when bacteriological, serological and radiological investigations had failed to reveal the diagnosis. Laparoscopy proved helpful in making the diagnosis in 68.4% of these patients; in 44.2% it provided a definite diagnosis, and in 24.2% it contributed significantly to the establishment of a diagnosis. Laparoscopy was of most use (76.6%) in those patients with physical signs or biochemical results suggestive of an abdominal disorder. In the absence of such sign laparoscopy was helpful in only 20.0% of patients. There was no mortality, and morbidity was insignificant. It is our conclusion that laparoscopy can be recommended in FUO, particularly in patients with signs of abdominal disease.
