Mach等对56例干燥综合征患者及18例健康者,着重进行了唾液内IgA、IgG和IgM的定量分析。作者观察到,习惯用于诊断本征的各种临床试验价值并不一致,唾液腺导管X线造影最为可靠。唾液腺活检虽然很有价值,但可能由于淋巴样浸润的局限性,而并非特异性。作者认为,唾液内IgG和/或IgM的存在,如结合临床分析,与唾液腺导管X线造影具有同样的特异性。仅见于健康人的IgA,在本征患者中大多增 Mach and other 56 cases of Sjogren’s syndrome and 18 healthy subjects, focusing on quantitative analysis of IgA, IgG and IgM in saliva. The authors observed that the values ​​of various clinical trials customarily used for the diagnosis of eigenmas were inconsistent and that salivary gland duct radiography was the most reliable. Salivary gland biopsy, while valuable, may not be specific due to the limitations of lymphoid infiltration. The authors concluded that the presence of IgG and / or IgM within saliva, as with clinical analysis, is as specific as salivary duct radiography. Only seen in healthy people IgA, most of the increase in the intrinsic patients
