Abstract:

Objective: To investigate the clinical manifestations, electromyographic abnormalities and laboratory characteristics of primary Sjögren′s syndrome (pSS) complicated with peripheral neuropathy and to analyze the risk factor of pSS complicated with peripheral neuropathy. Methods: A retrospective analysis was performed on 132 pSS patients who met the 2002 American-European Consensus Group criteria for pSS at Tongji Hospital from January 2015 to September 2017. The patients were categorized into group with peripheral neuropathy (pSS-PNS) and group without peripheral neuropathy (pSS-nPNS). The clinical manifestations, corresponding examinations and laboratory characteristics of the two groups were compared. The data were analyzed by t test, χ2 test and logistic regression analysis. Results: A total of 132 patients with pSS were enrolled in this study, including 12 males and 120 females. The ratio of male to female was 1∶10. Among them, 21 patients suffered from peripheral nervous system involvement and the prevalence rate was 15.9%(21/132). There were no significant differences in gender composition, age, onset age and course between the two groups. Compared with the group without peripheral neuropathy, joint swelling and pain (71.4% and 44.1%, P=0.02) were more common in the group with peripheral neuropathy, and CD8 [(21.25±13.11)% and(26.65±9.44)%, P=0.02] decreased significantly, ratio of CD4/CD8(2.80±1.45 vs 1.91±1.12, P=0.04) increased significantly. ESSDAI (European League Against Rheumatism Sjögren′s Syndrome Disease Activity Index) score [(4.71±0.46) and (2.80±0.17) ] was significantly higher in pSS-PNS group. ESSDAI (OR=1.836, 95%CI 1.169-2.883, P=0.008) was an independent risk factor for pSS with peripheral neuropathy. Conclusions: The clinical manifestations of pSS complicated with peripheral neuropathy are diverse, and the disease activity is high. High disease activity is an independent risk factor for Sjögren′s syndrome complicated with peripheral neuropathy.
