Abstract:
:The composition of glycosaminoglycans (GAGs) was analyzed in skin samples of eight patients suffering from localized scleroderma, i.e., three having generalized morphoea and five localized morphoea plaques. From each patients, biopsies were obtained from sclerotic and perilesional areas, and from clinically uninvolved skin of the same region. In the perilesional areas hyaluronic acid concentration was increased (p less than 0.05), while it was decreased (p less than 0.01) in sclerotic areas. Dermatan sulfate concentration was increased in the perilesional (p less than 0.05) as well as in the sclerotic (p less than 0.01) areas. Chondroitin 4/6 sulfate was increased in the sclerotic areas (p less than 0.05). Heparan sulfate showed no changes. No major differences were found in the total concentrations of uronic acid and hexosamine. This study demonstrates that changes in GAG composition in localized scleroderma follow previously described sequences of events of inflammation and fibrosis of connective tissue.
