Abstract
OBJECTIVE: The objective of this study is to compare the clinical and laboratory features of Japanese patients with IgG4-related disease, with and without allergic conditions. METHODS: We retrospectively examined the clinical and laboratory features and clinical courses of 51 patients with definitively diagnosed IgG4-RD, collected from Nagaoka Red Cross Hospital between January 2004 and August 2017, with reference to the presence of allergic conditions. RESULTS: Among these patients, 43% had allergic conditions. In the allergy group, the proportion of females was significantly higher, the age at diagnosis was significantly lower, and upper body organ involvement was predominant in comparison with the non-allergy group. There was no significant inter-group difference in the absolute number of peripheral blood eosinophils, the levels of serum IgG4 and IgE, the response to steroid, or the proportion of patients who relapsed. CONCLUSION: The present findings suggest that there may be some differences in the clinical features of IgG4-RD patients according to the allergic conditions that are present, although eosinophilia and high serum levels of IgE and IgG4 are common features regardless of allergy.
