Hyperprolactinemia in Reiter's syndrome.

Objective. Accumulated evidence suggests that certain immunoregulatory hormones including prolactin (PRL) may play a role in the pathogenesis and disease expression of certain autoimmune diseases, Our objective was to investigate the possible role of PRL in the pathogenesis and disease expression of the spondyloarthropathies, including Reiter's syndrome (RS). Methods. Basal levels of PRL (serum) were determined by radioimmunoassay in patients with various types of spondyloarthropathies, patients with acute anterior uveitis (AAU), and healthy controls, Clinical manifestations at the time of serum collection were correlated with PRL levels
