The medical and surgical treatment of finger clubbing and hypertrophic osteoarthropathy. A blind study with colchicine and a surgical approach to finger clubbing reduction.

Abstract

In fourteen patients affected with pachydermoperiostosis (PDP), or primary hypertrophic osteoarthropathy, the efficacy of colchicine (0.5 mg day for one month) versus placebo on the main clinical features of the disease (finger clubbing, arthritis and pachydermia) was evaluated. In addition, in one patient the usefulness of surgical reduction of clubbed fingertips was investigated. Colchicine did not demonstrate any appreciable effect on finger clubbing (expressed in degrees) or pachydermia, while an effect on arthralgia (as evaluated by the Ritchie Index and Pain Scale) was observed. The surgical treatment of clubbed fingertips failed to show a satisfactory and stable reduction of the fingertips; two months after surgery the nail matrix apparently produced new tissue, once again enlarging and deforming the finger. These results suggest that low dose colchicine cannot be considered the drug of first choice for the treatment of PDP, while higher dosages, although effective, are not tolerated because of the severe side effects. An effective medical and surgical treatment for PDP will be found only when the pathogenetic mechanisms of the disease are clarified.
