Long-term follow-up of patients with primary biliary cirrhosis on colchicine therapy.

| Abstract |
We followed up a group of patients with primary biliary cirrhosis who participated in a 4-yr prospective, double-blind controlled trial of colchicine therapy for 4 additional years. All were placed on open label colchicine (0.6 mg twice daily) after the trial was concluded. Of the original group of 28 patients treated with colchicine, 8 died and 5 received transplants (3 of the 5 died). Of the original placebo control group eight patients died and six received transplants (1 of the 6 died). Surviving patients on long-term colchicine therapy (mean period = 8.1 yr, range = 5.3 to 9.1) showed reduction of mean serum alkaline phosphatase from 5.1 times the upper limit of normal values to 1.9 times (p less than 0.01). Mean ALT fell from 1.8 to 1.2 times the upper limit of normal (p = 0.05), and mean serum total bilirubin remained stable (1.6 mg/dl vs. 1.5 mg/dl). Major complications of cirrhosis developed in four patients in the colchicine group and five patients in the original control group. The only side effect of colchicine was diarrhea, which was noted in three patients. The diarrhea resolved with reduction in the dose of colchicine. Colchicine is a safe and inexpensive drug for the long-term treatment of primary biliary cirrhosis. The biochemical parameters of disease activity (alkaline phosphatase and ALT) remain improved after long-term follow-up, and bilirubin values remain stable. However, complications of cirrhosis, deaths and transplantations were not prevented. The clinical usefulness of colchicine in the treatment of primary biliary cirrhosis seems to be limited.
