Jazzar A, et al. - Researchers determined if selected tests of salivary gland function and structure [unstimulated whole salivary flow rate (UWSFR), parotid flow rate (PFR), clinical oral dryness score (CODS) and ultrasound score (USS)] can discriminate SS from non-SS sicca patients. In addition, they investigated the efficacy of these tests in differentiating patients in different subgroups of SS. In 244 patients [comprising of SS patients (n=118), SS patients at higher risk of lymphoma (n=30) or with lymphoma (n=26), and non-SS sicca disease controls (n=70)], they determined UWSFR, PFR, CODS and USS. As per outcomes, salivary gland tests including USS seem to have the potential for differentiating between SS and non- SS dry mouth, especially the subgroups of SS with lymphoma or at higher risk of developing lymphoma.
