ABSTRACT

Objective:

To detect the factors related to hemocytopenia and interstitial lung disease (ILD) secondary to primary Sj?gren's syndrome (pSS) in in-patients.

Methods:

Clinical characteristics of patients with pSS hospitalized in China-Japan Friendship Hospital from March 2014 to October 2020 were retrospectively analyzed. Patients were divided into different groups according to hemocytopenia and ILD. Chi-square test and Mann-Whitney U test were used to compare data in subgroups, and logistic regression were used to detect factors related to hemocytopenia and ILD secondary to pSS.

Results:

Five hundred and seventy-one inpatients with pSS were included in this study and the female male ratio was 8∶1. Two hundred and seventy five of included patients had hemocytopenia (48.2%) and 180 patients had ILD (31.5%). Compared with patients without hemocytopenia, patients with hemocytopenia had higher ratio in low C3 [ OR=2.326, 95% CI(1.483, 3.650), P<0.01] and elevation of erythrocyte sedimentation rate (ESR) [ OR=1.912, 95% CI(1.233, 2.964), PP<0.01) . Compared with patients without ILD, patients with ILD showed higher ratio in male[ OR=2.509, 95% CI(1.269, 4.959), P<0.01) and fatigue [ OR=5.190, 95% CI(5.190, 13.931), P<0.01) , lower positive rate of anti-SSA antibody [ OR=0.392, 95% CI(0.230, 0.668), P<0.01) and anti-CENPB [ OR=0.337, 95% CI(0.145, 0.782), P<0.01] antibodies, and lower ratio in low C3[ OR=0.332, 95% CI(0.189, 0.582), P<0.01].

Conclusion:

Low C3 and high ESR may be risk factors for developing hemocytopenia in patients with pSS. Men with pSS may be susceptible to ILD, while pSS patients with ILD may have lower ratio in positive anti-SSA antibody, positive anti-CENPB antibody and low C3. All of these findings are yet to be validated by future prospective cohort studies.
