Abstract:
Objective To analyze the clinical characteristics of IgG4-related disease (IgG4-RD)so as to improve the understanding of IgG4-RD in China.Methods IgG4-RD patients were recruited from Peking Union Medical College Hospital between January 2011 and January 2016.All patients were followedup for more than 6 months.The demographic characteristics,symptoms,organ involvements,laboratory examinations and treatment efficacy were evaluated and analyzed.Results A total of 346 patients were finally enrolled,including 230 males (66.5％) and 116 females (33.5％).The mean age of disease onset was (53.8 ± 14.2) years old.The mostly common involved organs were lymph nodes (56.4％) and submandibular glands (52.6％).Other affected organs and manifestations included:swelling of the lacrimal glands (46.5％),autoimmune pancreatitis (38.4％),pulmonary involvement (28.0％),sclerosing cholangitis (25.4％),naso-sinusitis (23.4％),parotid gland swelling (21.7％),retroperitoneal fibrosis (19.9％),large arteries involvement (9.5％),kidney involvement (obstructive nephropathy caused by retroperitoneal fibrosis was excluded) (6.9％),skin lesions (6.4％).Rare features consisted of thyroid glands,pituitary glands,gastrointestinal tract,pachymeningitis,pericardium,sclerosing mediastinitis and orchitis.The majority of patients had multi-organ involvement,such as 74.3％ patients with 3 and more,18.2％ and 7.5％ patients with 2 and single organ involvement respectively.The average IgG4-RD responder index (IgG4-RD RI) was 13.21 ±5.70.History of allergy was found in 172 (49.7％) patients.As to the laboratory tests,elevated serum IgG4 levels were confirmed in 285 (94.1％) patients,which was positively correlated with IgG4-RD RI.There were 33.5％ patients receiving monotherapy of glucocorticoid,52.6％ treated with glucocorticoids combined with immunosuppressive agents,4.9％ patients with immunosuppressant only,and 9.0％ patients with mild disease not receiving medication.The majority (336,97.1％) patients improved the above regimens.Conclusion IgG4-RD is a systemic fibro-inflammatory disease with multiple organ involvement.The mostly common involved organs include lymph node,submandibular glands,and pancreas.Glucocorticoids and immunosuppressive agents were effective for IgG4-RD.
