Rheumatoid arthritis affects primarily the synovial joints, but is often accompanied by extra-articular manifestations, including lacrimal and salivary gland involvement. The aim of the present study was to estimate the prevalence of ocular and oral sicca symptoms and reduced lacrimal and salivary flow in rheumatoid arthritis and the relation between sicca symptoms and objective measures of lacrimal and salivary flow.
We examined 88 consecutive hospitalized patients with rheumatoid arthritis and 88 age- and gender-matched healthy controls. The examination included the standardized questionnaire for keratoconjunctivitis sicca and xerostomia which forms part of the European criteria for Sjögren's syndrome, the Schirmer's I test and measurement of unstimulated whole salivary flow rate.
A significantly higher proportion of patients (40.9%) reported ocular sicca symptoms than healthy matched controls (8.0%). Further, a significantly higher proportion of patients (44.3%) reported oral sicca symptoms compared to controls (13.6%). 48.9% of the patients had low Schirmer I score, compared to 20.5% of controls. Reduced salivary flow was found in 27.3% of patients, compared to 9.1% of controls. The differences in lacrimal and salivary flow between patient and control group were statistically significant. The minimum prevalence of secondary Sjögren's syndrome was 14.8%. Weak association was observed between sicca symptoms and the objective measures of lacrimal and salivary flow in patients, and no association was detected in control subjects.
Sicca symptoms and reduced lacrimal and salivary flow were common manifestations in rheumatoid arthritis and should be given adequate consideration during management of patients with rheumatoid arthritis.
类风湿关节炎主要影响滑膜关节,但常伴有关节外表现,包括泪腺和唾液腺受累。本研究旨在评估类风湿关节炎患者眼部和口腔干燥症状及泪液和唾液流量减少的发生率,以及干燥症状与泪液和唾液流量客观测量之间的关系。
我们检查了 88 例连续住院的类风湿关节炎患者和 88 名年龄和性别匹配的健康对照者。检查包括角膜结膜炎干燥症和口干的标准化问卷,这是干燥综合征欧洲标准的一部分,还包括 Schirmer I 试验和非刺激性全唾液流量测量。
有明显更高比例的患者(40.9%)报告眼部干燥症状,而健康匹配对照者(8.0%)则较低。此外,有明显更高比例的患者(44.3%)报告口腔干燥症状,而对照组为(13.6%)。与对照组(20.5%)相比,48.9%的患者 Schirmer I 评分较低。在患者中发现唾液流量减少的比例为 27.3%,而对照组为 9.1%。患者组和对照组之间的泪液和唾液流量差异具有统计学意义。二级干燥综合征的最低患病率为 14.8%。在患者中观察到干燥症状与泪液和唾液流量的客观测量之间存在弱关联,但在对照组中未检测到关联。
干燥症状和泪液及唾液流量减少是类风湿关节炎的常见表现,在管理类风湿关节炎患者时应给予充分考虑。
