Abstract
OBJECTIVE: The purpose of this study was to compare the level and relative ratio of estrogen, progesterone, and prolactin in patients with Sjögren's syndrome and healthy controls. STUDY DESIGN: Serum samples were collected from 17 SS patients and 19 age-, sex- and race-matched controls. All subjects were postmenopausal females who were not currently on hormone replacement therapy. Prolactin levels were measured using ELISA and progesterone and estrogen were measured using EIA. RESULTS: Mann-Whitney U test revealed a significantly higher levels of prolactin among patients than controls (11.41 ng/ml vs. 6.74 ng/ml, p=0.003) with significantly higher prolactin/ progesterone (18.88 vs. 8.14, p=0.02) and estrogen/ progesterone (71.51 vs. 42.02, p=0.05) ratios. No significant differences were observed in the levels of estrogen and progesterone between patients and controls. CONCLUSION: Abnormal levels and relative ratios of hormones may play a role in the pathogenesis of Sjögren's syndrome.
