Urinary Excretion of Acid Mucopolysaccharides and Hydroxyproline in Psoriasis

Abstract
The urinary output of acid mucopolysaccharide and hydroxyproline was determined in control and in psoriatic patients. The excretion of both was increased in nummular psoriasis by an amount which was statistically significant, while in psoriasis pustulosa and arthritic psoriasis the excretion of acid mucopolysaccharide increased further and the excretion of hydroxyproline dropped to normal values.
