title: Increased beta 2-microglobulin in both parotid and submandibular/sublingual saliva from patients with Sjögren's syndrome.
abstract: Samples of unstimulated saliva from patients with sialoadenopathy were collected by microcapillary tube (1 microliter), and their beta 2-microglobulin (B2-MG) content determined by a sandwich enzyme immunoassay. A higher than normal (control) concentration of the globulin was present in both parotid and submandibular/sublingual saliva from the patients with Sjögren's syndrome but not in the samples from the patients with sialoadenitis or diabetes mellitus. The increase in B2-MG in saliva from patients with Sjögren's syndrome may reflect that immunolopathological events are important in the degeneration of both glands in this disease. Therefore, the determination of B2-MG in saliva may be a simple, non-invasive technique for confirming the diagnosis of Sjögren's syndrome as an autoimmune disease.
