Utility of salivary gland biopsy in diagnosing Sjogren's syndrome in a POTS patient population

Purpose POTS patients undergo labial salivary gland biopsies (LSGB) for histologic confirmation of Sjogren's syndrome (SS). Predictive features of positive results are unknown. Methods 161 POTS patients underwent LSGB. Their charts were reviewed for antibody and diagnostic testing results. Results Only 11% (17/161) of POTS patients were SS positive. There were more positive ANA antibodies in those with positive LSGB (65% v 28%, p = .0026)....
