RESULTS: Besides xerostomia and xerophthalmia, fatigue, polyuria and bone pain were found in 7 patients. Osteoporosis occurred in 6 cases and renal insufficiency in 3 cases. Immunoglobulin was increased in 7 cases, including 7 with IgG increase and 4 with IgG, IgA and IgM increase. All patients showed different degrees of ionic disorder and vitamin D deficiency. Renal glycosuria and amino acid urine were found in all 7 patients. All patients were treated with glucocorticoid combined with immunosuppressive agents.
