Cell-controlling factors in Dupuytren's contracture.

Abstract

The search for the causative factors in Dupuytren's disease has historically progressed form gross anatomical dissection, through microscopical tissue studies, to the biochemistry of the collagen produced. But these elements are merely the end products of cellular activity - not revealing the factors responsible for the changes in cellular activity. Recent biochemical investigations suggest that a number of conditions including localized microvascular ischemia and high alcohol concentrations transform the "benign" xanthine dehydrogenase of endothelial cells to the oxygen-free radical-releasing xanthine oxidase. Oxygen-free radicals are highly reactive species with half-lives in the order of milliseconds capable of both damaging the surrounding peri-microvasculature and stimulating fibroblast proliferation. It is this stimulation of fibroblast proliferation in the palmar fascia that is the key event in the pathogenesis of Dupuytren's contracture.
