Quality of life and psychological status in patients with primary Sjögren's syndrome and sicca symptoms without autoimmune features.

Objective: To compare pain, fatigue, and sicca symptoms; quality of life; and psychological status between patients with primary Sjögren's syndrome (SS) and those with sicca symptoms but no autoimmune features (sicca asthenia polyalgia syndrome [SAPS]), and to determine whether a psychological pattern can be detected in patients with SAPS, which could suggest psychological distress as the cause.

Methods: This cross-sectional, prospective study included 111 patients with primary SS according to the American-European Consensus Group criteria and 65 SAPS patients with no focus on lip biopsy and no anti-SSA/SSB antibodies. Pain, fatigue, and sicca symptoms were assessed using visual analog scales; quality of life was assessed using the Short Form 36 (SF-36); and psychological distress by the Symptom Checklist-90-Revised (SCL-90-R) questionnaire.
