Clinical characteristics of IgG4-related disease: analysis of 29 cases
① 29例临床诊断IgG4相关疾病,其中男∶女=1.64∶1;②颌下腺肿大、多发淋巴结肿大是IgG4相关疾病最常见的症状表现,肺、肝、泪腺/眼睑、胸膜、心包膜、胰腺、皮肤、胆道、腮腺、肾脏、乳腺等多器官均可受累;③29例患者血清IgG4介于57.3~2 000.0 mg/dL,约93.1% IgG4-RD血清IgG4升高,IgG升高比例为53.8%;④29例患者中10例予糖皮质激素和/或免疫抑制剂治疗后病灶缩小,IgG4降低,预后得到改善。
To analyze the clinical characteristics of IgG4-related disease (IgG4-RD) and to explore the clinical significance of serum IgG4 elevation in auxiliary diagnosis of IgG4-RD.
Methods
2
Clinical data of the patients diagnosed with IgG4-RD in our hospital from January 2010 to November 2020 were collected
and their clinical manifestations
involved organs
results of laboratory examinations
histopathology and treatment were retrospectively analyzed.
Results
2
① Among the 29 cases eventually enrolled
there were 18 males and 11 females
with a ratio of male to female of 1.64; ② Submandibular gland enlargement and multiple lymph node adenopathy were the most common symptoms. And multiple organs such as the lung
liver
lacrimal gland/eyelid
pleura
pericardium
pancreas
skin
biliary tract
parotid gland
kidney and breast were also afflicted; ③ Their serum IgG4 level ranged from 57.3 to 2 000.0 mg/dL. About 93.1% of them had elevated IgG4 level
and 53.8% got IgG elevation; ④ Ten cases were treated with glucocorticoid and/or immunosuppressant
and they got shrunk lesions
dropped IgG4 level and good prognosis.
Conclusion
2
IgG4-RD is more common in middle-aged and elderly men
involving multiple organs
with various initial symptoms and clinical manifestations. Serum IgG4 is an important indicator for the diagnosis of IgG4-RD
but vasculitis
tumor diseases
infectious diseases
Castleman disease and other connective tissue diseases should be carefully excluded.
