In a cross-sectional study of 130 patients (main diagnosis: rheumatoid arthritis, n = 41, osteoarthritis, n = 39; ankylosing spondylitis, n = 28) we measured the concentrations of hyaluronan (HA) and the N-terminal propeptide of type-III collagen (NP III P) in urine and evaluated the relationship with their serum levels. Increased HA levels in serum correlated with increased urinary excretion (r = 0.69 for patients with active rheumatoid arthritis). Only patients with rheumatoid arthritis showed significantly elevated HA concentrations in urine (mean = 1,493 micrograms/mmol creatinine). Because of relatively wide fluctuations in urinary HA in normals (mean = 944, standard deviation 818 micrograms/mmol creatinine) and only modest differences between groups, the diagnostic accuracy of urinary HA measurements is inferior to serum determinations. NP III P showed no significant differences between patients and controls (means 10.5 to 15 micrograms/mmol creatinine). Obviously, renal excretion is of minor importance in the metabolism of HA and NP III P. The possible diagnostic usefulness of determinations of these parameters in serum is not enhanced by measurements in urine.

D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010003	Osteoarthritis	A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.
