A double-blind randomized controlled trial of colchicine in patients with hepatitis B virus-related postnecrotic cirrhosis.
ABSTRACT The preliminary results of a prospective double-blind controlled trial of colchicine in 100 patients with hepatitis B virus-related cirrhosis are reported. The patients, 94 males and 6 females, aged 32-80, were assigned to receive either 1 mg of colchicine or an identical placebo orally on a daily basis. The duration of the follow up ranged from 15 to 51 months (median 26 months). Seventy percent had histological proof of cirrhosis. On entry, 80 patients were in Child-Pugh class A, 19 were in class B, and one was in class C. Compared to the placebo group, there was no improvement in the colchicine group after a 24-month follow up in any of the biochemistry data, for example, serum albumin, alkaline phosphatase, alanine and aspartate aminotransferase, bilirubin, and prothrombin time. The difference in the cumulative survival rates at 51 months did not reach statistical significance (p = 0.8) in either group. There was no histological improvement in 30 patients who were willing to undergo repeated liver biopsies. No trend toward improvement of the hepatic pressure gradient was observed in these patients. The serum levels of aminopropeptide of type III procollagen increased significantly in patients in both groups after 24 months of therapy (1.07 +/- 0.06 vs. 1.36 +/- 0.06 U/ml in the colchicine group, 0.93 +/- 0.09 vs. 1.25 +/- 0.07 U/ml in the placebo group; p < 0.05). In addition, neither the clinical deterioration of cirrhosis nor death was prevented in patients receiving colchicine therapy. This report indicates that colchicine has no effect in the treatment of HBV-related postnecrotic cirrhosis.

ABSTRACT: Colchicine is an anti-inflammatory and anti-fibrotic drug. Several randomized clinical trials have addressed the question whether colchicine has any efficacy in patients with alcoholic as well as non-alcoholic fibrosis and cirrhosis. The objectives were to assess the efficacy of colchicine evaluated in randomized trials on mortality, liver related mortality, liver related complications, liver fibrosis markers, liver histology, alcohol consumption, quality of life, and health economics in patients with alcoholic and non-alcoholic fibrosis or cirrhosis. Interventions encompassed peroral colchicine at any dose versus placebo or no intervention. The trials could be double-blind, single-blind or unblinded. The trials could be unpublished or published as an article, an abstract, or a letter, and no language limitations were applied. All analyses were performed according to the intention-to-treat MEDLINE, The Cochrane Controlled Trials Register, The Cochrane Hepato-Biliary Group Controlled Trials Register and full text searches were combined. Combining the results of 14 randomized clinical trials including 1138 patients demonstrated no significant effects of colchicine on mortality (odds ratio (OR): 0.91; 95% confidence interval (CI) 0.64, 1.31), liver related mortality (OR: 0.98; CI 0.56, 1.74), complications (OR: 1.06; CI 0.65, 1.73), and the other outcomes. Colchicine was associated with a significantly increased risk of adverse events (OR: 4.41; CI 2.24, 8.70; p< 0.001). Colchicine should not be used for liver fibrosis or liver cirrhosis irrespective of etiology. Future trials on colchicine for liver diseases ought to be large.Liver International 04/2001; 21(2):129-36.

ABSTRACT: Liver fibrosis is a common pathway leading to cirrhosis, which is the final result of injury to the liver. Accurate assessment of the degree of fibrosis is important clinically, especially when treatments aimed at reversing fibrosis are being evolved. Liver biopsy has been considered to be the "gold standard" to assess fibrosis. However, liver biopsy being invasive and, in many instances, not favored by patients or physicians, alternative approaches to assess liver fibrosis have assumed great importance. Moreover, therapies aimed at reversing the liver fibrosis have also been tried lately with variable results. Till now, there has been no consensus on various clinical, pathological, and radiological aspects of liver fibrosis. The Asian Pacific Association for the Study of the Liver set up a working party on liver fibrosis in 2007, with a mandate to develop consensus guidelines on various aspects of liver fibrosis relevant to disease patterns and clinical practice in the Asia-Pacific region. The process for the development of these consensus guidelines involved the following: review of all available published literature by a core group of experts; proposal of consensus statements by the experts; discussion of the contentious issues; and unanimous approval of the consensus statements after discussion. The Oxford System of evidence-based approach was adopted for developing the consensus statements using the level of evidence from 1 (highest) to 5 (lowest) and grade of recommendation from A (strongest) to D (weakest). The consensus statements are presented in this review.Hepatology International 07/2009; 3(2):323-33. · 2.64 Impact Factor
