AbstractPatients with chronic inflammation often show decreased serum levels of trace elements. This study aimed to investigate serum levels of selenium and zinc in patients with uveitis. Twenty-four patients (13 female, 11 male) with a mean age of 40.6 +/- 15.5 yr were included in this study. According to their underlying disease, they were divided into acute (n = 13) or chronic (n = 11) uveitis. Selenium and zinc determination was performed by atomic absorption spectroscopy in EDTA blood samples. Patients with acute or first-time uveitis showed selenium and zinc concentrations within the normal range. In contrast to this, patients with chronic recurrent uveitis tend to result in decreased selenium and zinc levels. Especially selenium showed a remarkable reduction in serum concentration below the normal range. Furthermore, there was a tendency to decreased trace element concentrations with increasing age. A sex dependency could not been found. Especially patients with chronic, recurring uveitis show remarkable decreased selenium concentration in the EDTA-blood. Further studies should investigate possible positive effects of therapeutic selenium and zinc supplementation in patients with chronic, recurrent uveitis.
