I also have both Raynaud's and Dupuytrens. I got a raging case of Raynauds quite suddenly about 15 years ago (living in Florida, no less!) and developed very aggressive Dupuytren's within 2 years after that. Still have both afflictions obviously - it was in the high 50's (F) this morning (winter in Florida) and I wore wool gloves to get from home to car to office - truly cold weather is torture. As for medical studies linking the 2 diseases, there really isn't anything substantial in the medical literature. This is all I could find (I'm a science librarian). Kristen

Concerning the question whether a correlation between the vasospasm and morphological changes in the neuro-myo-arterial glomerular (Hoyer-Grosser-Organ) exists also in Dupuytren disease, a series of 18 patients with Dupuytren and 5 patients with Raynaud disease were studied by finger venous occlusion plethysmography and finger tip biopsies. No typical histological changes were found in Dupuytren's Contracture, particularly none in the 13 cases (70%) which had a latent vasospasm and none in the 5 cases (30%) which had a normal plethysmogram, whereas in all the patients with Raynaud disease the typical morphological changes of wall, lumen and morphometric counts of the "Suquet-Hoyer" canals were found in correspondance to the abnormal plethysmogram. According to these results the vasospasm of Dupytren and Raynaud disease seems to be pathogenetically different.

May never know about a connection.....More males get Dups...More females get Raynauds..
