OBJECTIVES: To assess the prevalence of abnormal smell and taste perception in people with primary SS and the effect on quality of life (QoL). METHODS: Twenty-eight participants with SS and 37 controls were enrolled in a cohort-matched, prospective, cross-sectional study. Smell and taste thresholds were measured using standardized, validated tests. QoL was assessed by the Short Form 12 (SF-12). RESULTS: Smell threshold was reduced by 1 point (P = 0.002; 95% CI 0.35, 1.54) and taste threshold was reduced by 3.5 points (P < 0.001; 95% CI 1.80, 5.22) in the SS group compared with controls. The physical and mental components of SF-12 were reduced by 14.2 points (P < 0.001; 95% CI 9.47, 19.02) and 7.5 points (P = 0.002; 95% CI 2.97, 12.02), respectively, in the SS group compared with controls. Taste threshold was significantly correlated with both the physical (r = 0.48; P < 0.001) and the mental (r = 0.30; P = 0.015) components of SF-12. Smell threshold correlated with the physical (r = 0.457; P < 0.001), but not the mental component (r = 0.154; P = 0.222) of SF-12. CONCLUSIONS: Clinically important impairment of chemosensory perception occurred in the SS group compared with age- and gender-matched controls. Assessment using SF-12 suggests that this impairment contributed to the reduced health-related QoL that characterized these individuals.
