Session Title: Miscellaneous Rheumatic and Inflammatory Diseases Poster II
Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose: To study the clinical characteristics of IgG4-RD patients in China
Methods: Patients were recruited from a prospective cohort study of IgG4-RD in Peking Union Medical College Hospital between 2011 and 2016, who were followed-up for more than 6 months. The demographic characteristics, organ involvements, the laboratory examinations and treatment were analyzed
Results: A total number of 346 patients were enrolled, including male 230 (66.5%), female 116 (33.5%).The age of disease onset was 53.8 ± 14.2 years old. The mostly common related organ onset was lymphadenopathy (56.4%), submandibular glands (52.6%). Other affected organs included: swelling of the lacrimal glands (46.5%), autoimmune pancreatitis (38.4%), pulmonary involvement (28.0%), sclerosing cholangitis (25.4%), naso-sinusitis (23.4%), salivary swelling were (21.7%), retroperitoneal fibrosis (19.9%), large arteries involvement (9.5%), kidney involvement (6.9%), skin lesions (6.4%), Rarely involved organs were thyroid glands, pituitary glands, gastrointestinal tract, pachymeningitis, pericardium, sclerosing mediastinitis and orchid. The majority of patients had multi-organ involvement, 74.3% of patients with 3 and more organs involvement 18.2% and 7.5% of patients with 2 and single organ involvement respectively. The average IgG4-RD responder index (IgG4-RD RI) was 13.21±5.7. History of allergy was found in 172(49.7%) patients. Of the laboratory tests, elevated serum IgG4 levels were found in 285(94.1%) patients, and positively correlated with IgG4-RD RI. Of treatment, 33.5% patients received treatment of glucocorticoids, 52.6% patients were treated with glucocorticoids combined with immunosuppressors, 3.2% patients were treated with immunosuppressors, and 9.0% patients received no drugs at baseline evaluation. Most patients improved after regular drug treatment.
Conclusion: IgG4-RD is a systemic fibro-inflammatory disease with multiple organs involvement. The mostly common related organs respectively were lymph node, submandibular glands, and pancreas. Glucocorticoids and immunosuppressors were effective treatment strategies of IgG4-RD.
