title: Relationship between plasma levels of hyaluronic acid and amyloid-associated osteoarthropathy in chronic hemodialysis patients.
abstract: Plasma levels of hyaluronic acid (HA) and acute-phase reactants were determined in chronic hemodialysis patients with or without carpal tunnel syndrome (CTS) and/or shoulder pain, which are characteristic symptoms of amyloid-associated osteoarthropathy. While levels of acute-phase reactants tended to be higher in the patients with CTS and/or shoulder pain than in patients without these symptoms, the difference was not significant. However, plasma levels of HA were significantly higher in the patients with these symptoms. Analysis of plasma levels of HA in age-matched patients also demonstrated a significant correlation between elevated levels of HA and the presence of CTS and/or shoulder pain. Among the patients with CTS and/or shoulder pain, those patients with bone cysts in the carpal bone or humeral head had significantly higher plasma levels of HA than patients without bone cysts. Thus, there appears to be a relationship between elevated plasma HA and amyloid-associated osteoarthropathy in chronic hemodialysis patients that is more specific than any correlation with levels of acute-phase reactants.
