Colchicine in the treatment of scleroderma.

We treated 10 patients with well established scleroderma with colchicine in the highest tolerated dose for one year. We could determine no clinical or laboratory improvement in any patient. Progression of disease was suggested by the development of new skin ulcers and telangiectasia, by an increase in musculoskeletal complaints, and by a significantly diminished ability to make a fist. In addition, there was deterioration of pulmonary function as demonstrated by a statistically significant fall in FEV1, and diffusing capacity. Colchicine was not of value in the treatment of scleroderma in this group of patients.
