Abstract:

Objective To verify the effect of triamcinolone acetonide(TA) and normal saline(NS) irrigating salivary glands on long-term relief of xerostomia in patients with Sjögren’s syndrome(SS). Methods A total of 49 SS patients were randomly divided into control group (no irrigation, n=16), NS group(NS irrigation, n=17) and TA group(TA irrigation, n=16). The examinations of the unstimulated whole salivary flow(UWS), chewing-stimulated total salivary flow(SWS), citric acid-stimulated parotid flow(SPF), clinical xerostomia score(CODS), xerostomia scale(XI) and EULAR SS patient-reported index(ESSPRI) were conductedat 1 week before irrigation(0W) and 8 weeks(8W), 16 weeks(16W), 32 weeks(32W) and 40 weeks(40W) after irrigation. Results The follow-up of 14 cases in each group was completed. Compared with 0W, the SWS and SPF of 8W, 16W, 24W and 32W were increased after TA and NS irrigation(P<0.05), but there was no significant difference at 40W(P>0.05). Compared with 0W, ESSPRI(oral dryness domain) was decreased in TA and NS groups at 8W, 16W and 24W and 32W(P<0.05). The SWS and SPF of the TA group at 16W, 24W and 32W were higher than those of the control group(P<0.05). The CDOS in the NS group at 8W, 24W, and 32W were lower than those of the control group(P<0.05). Conclusion TA and NS irrigation of the major salivary glands can continuously relieve xerostomia in SS patients for 32 weeks.
