Abstract
OBJECTIVE
To assess the prevalence of parotid gland swelling (PGS), and its association with features of Sjögren's syndrome (SS) and other causes of sialadenosis in a Latin-American cohort of primary SS.
METHODS
We included 668 patients from Argentina, Brazil, Mexico, and Paraguay. We retrospectively registered demographics, disease duration, oral/ocular symptoms, serology and scored the basal ESSDAI. We defined PGS as a recurrent or persistent increase of volume of any parotid glands during adulthood (self-reported and/or physical examination). We registered the presence of diabetes mellitus, dyslipidaemia, body mass index, and alcohol consumption. We used logistic regression analysis reporting OR and 95% CI.
RESULTS
PGS was present in 242 patients (36.2%): 78 previous to SS diagnosis, 86 concomitantly, 73 during follow-up, and five unknown. At the multivariate analysis, PGS was associated with RF (OR 2.47, 95% CI 1.1-6.5, p= 0.0001), basal articular ESSDAI domain (OR 1.63, 95% CI 1.01-2.6, p= 0.04), and alcohol consumption (OR 2.42, 95% CI 1.41-4-15). Patients with PGS during the follow-up had a higher prevalence of alcohol consumption (45.3%) compared with the remaining PGS cases (26.8%; OR 2.41 95% CI 1.2-4.7), or patients without parotid gland swelling (15.6%; OR 3.8 95% CI 1.7-8.2) in all the adjusted models.
CONCLUSION
PGS generally precedes or presents concomitantly with SS diagnosis, and is related to RF and articular activity. Alcohol consumption is an additional factor in PGS, especially during follow-up. The meaning of this last finding as well as its prognostic implications remains to be elucidated and deserves further evaluation in prospective studies.
