Abstract

Objectives: To describe primary Sjögren's disease (SjD) patients presenting no or low level of dryness and to compare them with SjD patients with oral or ocular dryness features.

Methods: All patients diagnosed with SjD according to AECG or ACR/EULAR criteria in our tertiary reference centre were included. Patients with high or low subjective symptoms or objective signs of dryness were compared.

Results: Overall, 509 patients were included for the comparison of patients with high (n=456) or low (n=53) level of subjective dryness and 472 for the comparison of patients with (n=359) or without (n=113) high objective dryness. Compared with patients with subjective dryness, patients without high subjective dryness were significantly younger (median 49 (39-62) years vs 58 (47-67) years, p<0.01), diagnosed earlier (median time from first symptoms to diagnosis 2 (0.5-4.5) years vs 4 (1-9.25), p=0.0056), more frequently anti-SSA positive ((83% vs 64%, p=0.008) and had less focal sialadenitis in minor salivary gland biopsy (69% vs 83%, p=0.02).The patients without high level of objective dryness (n=113) were also younger (51 (41-60) vs 58 (47-67) years, p<0.001) and were more frequently anti-SSA positive (79% vs 63%, p=0.002).In both groups, no difference was observed regarding disease activity.

Conclusions: Among the patients with SjD, those without high subjective or objective dryness features had a younger profile, a faster diagnosis which may result from a more acute onset, were more frequently anti-SSA positive than patients with high dryness features.
