Sialochemistry was undertaken to detect subclinical involvement of salivary glands in patients with rheumatoid arthritis (RA). The concentrations of salivary sodium and IgA were significantly elevated in 24 percent of the RA patients. Eighty per cent of the patients with elevated sodium and IgA concentrations had keratoconjunctivitis sicca as well. No correlation between serum and salivary IgA levels was found. The results indicate that salivary sodium and IgA levels can be used for detection of subclinical salivary gland involvement and for follow-up of RA patients.
开展唾液化学分析以检测类风湿性关节炎（RA）患者唾液腺的亚临床受累情况。24%的RA患者唾液钠和IgA浓度显著升高。钠和IgA浓度升高的患者中，80%也患有干燥性角结膜炎。未发现血清和唾液IgA水平之间存在相关性。结果表明，唾液钠和IgA水平可用于检测唾液腺的亚临床受累情况以及对RA患者进行随访。
