Abstract:
Objective To analyse the clinical features and risk factors of interstitial lung disease in primary SjSgren's syndrome (pSS).Methods A retrospective study was employed.All 130 pSS patients who were hospitalized during 2004 to 2006 were enrolled into this study.Thirty-seven clinical and laboratory variables were used as the research factors and interstitial lung involvement as the related factor.The data were analyzed with the Logistic regression model.Results of 130 patients,22(16.9%) had interstitial lung involvement.Twelve patients were asymptomic when pulmonary involvement was detected.Variables in the univariate analysis which were significantly associated with lung fibrosis were age,exocrine glands(including parotid,sublingual gland and submandibular gland) swelling,oral ulceration and fever.Positive rate of antiU1RNP antibody in group of lung damage was significantly higher than non-lung damage group [5/22(22.7%)vs 6/108 (5.6%),P=0.021].In the Logistic regression model.variables which were significantly associated with pulmonary involvement were exocrine glands swelling (OR=3.739,95%CI 1.069～16.079,P＜0.05).oral ulceration (OR=3.739,95%CI 1.069～16.079,P＜0.05)and fever (OR=3.067,95%CI 1.198～20.067,P＜0.05).Conclusions This study indicates that some of the pulmonary damages of pSS are subclinical.Exocrine glands swelling,oral ulceration and fever are the risk factors for interstitial pulmonary involvements in pSS.
