Chondroitin Sulfate, Dermatan Sulfate and Dupuytren's

Dermatan sulfate is similar to the nutritional supplement chondroitin sulfate, and used to be called chondroitin sulfate. Dermatan sulfate is unusually abundant in fascia affected by Dupuytren's. Is it the cause or is it the effect of the abnormal biology of Dupuytren's? Maybe both, as discussed in this review: http://www.dupuytrenfoundation.org/DupPDFs/2007_Kozma.pdf
