Urinary glycosaminoglycan excretion in systemic sclerosis subsets compared with normal controls

Urinary glycosaminoglycan (GAG) excretion was studied in 30 patients with established systemic sclerosis and compared with 30 normal controls. There was no significant difference in excretion values in the patient group as a whole, but in the group defined as 'incomplete CREST' urinary GAG values were lower than the group with 'diffuse disease' and controls.
