Treatment of cirrhosis with colchicine. A double-blind randomized trial.

As part of a double-blind, randomized, controlled trial to evaluate the effect of colchicine on liver cirrhosis, 43 cirrhotic patients were assigned to either a placebo (20 patients) or a colchicine (23 patients) treatment group. Colchicine 1 mg and an indistinguishable placebo were administered orally on a daily dose 5 days a week. In the colchicine group, 12 were males and 11 females, while in the control group 13 were males and 7 females. The time elapsed between diagnosis and inclusion in the study was 14.1 mo for the controls and 14.5 mo for the patients on colchicine. Mortality related to the liver disease occurred in 4 patients on colchicine and 8 patients on placebo. Although the probability of surviving in the colchicine group was greater than that of the placebo, the difference did not reach statistically significant levels. Of the colchicine-treated patients, in three a remarkable decrease in liver fibrosis was observed in serial biopsies. In two other patients, carcinoma of the liver developed. Six of the survivors on colchicine have improved clinically, noticing disappearance of ascites and edema, as well as a decrease in the size of the spleen. All the survivors on placebo continue to show clinical deterioration. In contrast to the usual drop of serum albumin seen in the cirrhotic patients, those receiving colchicine increased and maintained their serum albumin levels throughout the study. Serum proline values were elevated only in the alcohol cirrhotic patients. Serum alkaline phosphatase increased only in those patients receiving colchicine. The results indicate that in some cases, liver fibrosis could be modified by treatment with antifibrotic drugs. The use of colchicine at present should remain within controlled studies.
