| Outline of Final Research Achievements |
For the definitive diagnosis of IgG4-related disease (IgG4-RD), biopsies of local lesions are recommended so as to exclude other diseases. However, performing biopsies of underlying organs is technically difficult. In this study, we examined the diagnostic utility of labial salivary gland (LSG) biopsy as a less invasive procedure. Sixty-four patients with suspected IgG4-RD by clinical findings or high serum IgG4 underwent LSG biopsy. The sensitivity, specificity, and accuracy of LSG biopsy were 55.6%, 100.0%, and 68.8%, respectively. In the IgG4-RD patients witout lesions of salivary glands, the mean number of affected organs and serum IgG4 in the positive cases for LSG biopsy were significantly higher than in the negative cases. These results suggest that LSG biopsy combined with clinical findings, including serum IgG4 and number of affected organs, may contribute towards a diagnosis of IgG4-RD patients with affected underlying organs.
