Salivary Gland Tumors Diagnosis and Treatment

Primary Sjögren syndrome (pSS) is an autoimmune disorder characterized by ocular and oral dryness or systemic manifestations.To evaluate efficacy and harms of rituximab in adults with recent-onset or systemic pSS.Randomized, placebo-controlled, parallel-group trial conducted between March 2008 and January 2011. Study personnel (except pharmacists), investigators, and patients were blinded to treatment group. (ClinicalTrials.gov: NCT00740948).14 university hospitals in France.120 patients with scores of 50 mm or greater on at least 2 of 4 visual analogue scales (VASs) (global disease, pain, fatigue, and dryness) and recent-onset (< 10 years) biologically active or systemic pSS.Randomization (1:1 ratio) to rituximab (1 g at weeks 0 and 2) or placebo.Primary end point was improvement of at least 30 mm in 2 of 4 VASs by week 24.No significant difference between groups in the primary end point was found (difference, 1.0% [95% CI, -16.7% to 18.7%]). The proportion of patients with at least 30-mm decreases in at least two of the four VAS scores was higher in the rituximab group at week 6 (22.4% vs. 9.1%; P = 0.036). An improvement of at least 30 mm in VAS fatigue score was more common with rituximab at weeks 6 (P < 0.001) and 16 (P = 0.012), and improvement in fatigue from baseline to week 24 was greater with rituximab. Adverse events were similar between groups except for a higher rate of infusion reactions with rituximab.Low disease activity at baseline and a primary outcome that may have been insensitive to detect clinically important changes.Rituximab did not alleviate symptoms or disease activity in patients with pSS at week 24, although it alleviated some symptoms at earlier time points.
