The role of conjunctival epithelial cell xanthine oxidoreductase/xanthine oxidase in oxidative reactions on the ocular surface of dry eye patients with Sjögren's syndrome.
Previous papers examined lipid peroxidase levels and myeloperoxidase activity as products of oxidative and inflammatory reactions in the tear fluid of patients suffering from dry eye. The aim of the present paper was to investigate whether the enzymes xanthine oxidoreductase/xanthine oxidase known to generate reactive oxygen species contribute to oxidative reactions on the ocular surface. Xanthine oxidoreductase/xanthine oxidase were examined immunohistochemically as well as histochemically in conjunctival epithelial cells of patients suffering from dry eye. Patients with verified autoimmune dry eye (Sjögren's syndrome) participated in our study; normal eyes served as controls. Conjunctival epithelial cells were obtained by the method of impression cytology using Millicell membranes. The results revealed a pronounced expression, as well as activity of xanthine oxidoreductase/xanthine oxidase in the conjunctival epithelium of dry eye. It is suggested that reactive oxygen species which are generated by this enzymatic system, contribute to oxidative reactions on the eye surface of patients with ocular manifestations of autoimmune disease (Sjögren's syndrome).

Hypokalaemic alkalosis, acquired Gitelman's and Bartter's syndrome in chronic sialoadenitis.
Two patients with chronic sialoadenitis had features of Bartter's and Gitelman's syndrome, respectively. The main complaints were leg paraesthesiae and acute arthritis. A good response to oral K+ supplementation, allopurinol and low-dose prednisone was obtained. The features of Sjögren's-related renal diseases are reviewed. Topics: Adult; Aged; Alkalosis; Allopurinol; Anti-Inflammatory Agents; Antimetabolites; Bartter Syndrome; Calcium; Chronic Disease; Dose-Response Relationship, Drug; Female; Humans; Hypokalemia; Magnesium; Potassium; Prednisone; Sialadenitis; Sjogren's Syndrome; Syndrome | 1997 |
