Clinical Characteristics of Geographic Tongue in Patients with Primary Sjögren's Syndrome
To analyze the clinical characteristics of geographic tongue in patients with primary Sjögren's syndrome (pSS).
Method
2
Patients with pSS treated in the China-Japan Friendship Hospital from December 2018 to October 2021 were enrolled and divided into different groups according to the presence of geographic tongue or the severity. Phi correlation analysis,Chi-square test, and Mann-Whitney
test were used to analyze the clinical characteristics of patients with geographic tongue.
Result
2
A total of 182 pSS patients were included in this study,including 75 (41.2%) patients with geographic tongue and 107 (58.8%) without geographic tongue. Partial exfoliation was more common than total exfoliation, and the anterior part of the tongue was the most common exfoliation site. The number of patients with severe geographic tongue was more than those with mild-to-moderate geographic tongue. Compared with pSS patients without geographic tongue,those with geographic tongue were more common in fissured tongue (92.0%/41.1%,

P

φ

φ

φ
=0.469),negatively associated with phlegm-dampness syndrome (
φ

φ

0.4). There was no statistical difference in the disease activity index between patients with or without geographic tongue and severity.
Conclusion
2
More than 40% of pSS patients had geographic tongue accompanied by fissured tongue. Geographic tongue is positively associated with Yin deficiency syndrome and Qi deficiency syndrome,and negatively associated with phlegm-dampness syndrome, indicating that treatment should be based on tonifying Qi and nourishing Yin. Compared with pSS patients without geographic tongue, those with geographic tongue may have higher positive rate of some immune indicators,which deserves further exploration.
