IgG4-related ophthalmic disease

IgG4-related disease is a fibro-inflammatory condition with tendency to form tumors with inflammatory infiltrate with IgG4 rich plasma cells and elevation of IgG4 level in serum, which may affect virtually every organ and tissue in the organism. IgG4-related ophthalmic disease may present as dacryoadenitis, myositis, other orbital tissues, hypophysitis or pachymeningitis causing cranial neuropathies. The diagnosis of IgG4-related disease is based on a typical clinical scenario, supportive laboratory data, expected radiological characteristics and distinct histopathological and immunohistochemical features. Corticosteroid followed by the use of long-term immunosuppressive therapy is the most commonly attempted treatment.     

IgG4相关性眼病研究进展

IgG4相关性疾病是一种近几年才被认识的疾病,病因尚不明确。以同时或逐步出现的一种或多种组织和器官中大量IgG4阳性淋巴浆细胞浸润、席纹状纤维化、闭塞性静脉炎为特征,可伴有血清IgG4水平升高。当累及眼部时称为IgG4相关性眼病。任何眼附属器均可受累,多见于泪腺、眼眶脂肪、眶下神经、眼外肌和眼睑。本文将对近年来IgG4相关性眼病的流行病学特点、病理特点、临床表现、影像特点、诊断和治疗方面的最新进展作一综述。     

A clinicopathological study on IgG4-related ophthalmic disease

AIM: To investigate clinicopathological features of immunoglobulin G4-related ophthalmic disease (IgG4-ROD), and analyze the recurrence rates following systemic corticosteroid administration. METHODS: We retrospectively searched clinical features, laboratory and histological findings based on the medical records of 21 patients with IgG4-ROD. All the patients examined in this study underwent surgical resection in the ocular adnexal lesions and underwent histological evaluation. This study further investigated clinical and histopathological features of 15 patients who received systemic corticosteroid after the resection. RESULTS: The mean age of the patients consisting of 7 males (33%) and 14 females (67%) was 61y. Fourteen patients were diagnosed as definitive, and 2 and 5 patients were probable and possible IgG4-ROD, respectively. Eyelid swelling was an initial symptom in 11 patients (52%) who did not show systemic involvements at a diagnosis. Fifteen patients received systemic corticosteroid administration, and all showed remission of inflammation. Among them, 10 patients did not recur, whereas 5 patients (33%) recurred during tapering. There were no significant difference between patients with or without recurrence in clinicopathological features. CONCLUSION: In this study, female patients are more predominant in IgG4-ROD. While inflammation recurs in one-third of patients, this study do not identify factors associated with recurrence after systemic corticosteroid administration.

Unusual involvement of IgG4-related sclerosing disease in lacrimal and submandibular glands and extraocular muscles

Chronic sclerosing sialadenitis, also known as Kuttner tumor, is a chronic inflammatory disease of the salivary glands that is reported in a few cases in medical literature. Recent reports suggest that certain aspects of sclerosing diseases, including chronic sclerosing sialadenitis or dacryoadenitis, should be classified under immunoglobulin G4 (IgG4)-related sclerosing disease based on immunohistochemical studies. This study reports an unusual case of IgG4-related sclerosing disease appearing simultaneously in the lacrimal glands, submandibular glands, and extraocular muscles. A 56-year-old male presented with complaints of bilateral eyelid swelling and proptosis that began two years ago. Computed tomography confirmed that bilateral submandibular enlargements also existed five years ago in the subject. Orbital computed tomography and magnetic resonance imaging revealed bilateral lacrimal gland enlargement and thickening of extraocular muscles. Typical findings of chronic sclerosing dacryoadenitis were revealed upon pathologic exam of the right lacrimal gland. Immunostaining revealed numerous IgG4-positive plasma cells. Through these clinical features, we make a diagnosis of IgG4-relataed sclerosing disease in the subject.

IgG4相关性疾病眼部病变的临床及影像学特征分析

目的 探讨IgG4相关性疾病眼部病变的临床及影像学特征。设计 回顾性病例系列。研究对象 25例在2010年10月-2014年5月期间首诊于眼科并经实验室和（或）活组织检查证实的IgG4相关性疾病患者。方法 回顾性分析25例患者眼部病变的临床及影像学表现。主要指标 临床表现,眼眶MRI,生长抑素受体SPECT/CT显像（SRS）。结果 25例患者双眼睑肿胀、眼球突出为主要临床表现,其中23例为双眼受累,22例患者有≥2个器官受累,眼外受累器官多见于鼻部（19例）和涎腺（13例）。眼眶MRI主要表现为弥漫性泪腺增大（22例）、眼外肌增粗（14例）、眶周软组织浸润（10例）等。SRS显示治疗前眼眶摄取示踪剂显著增高（UR=1.87±0.43）;经免疫抑制治疗后活动期眼眶示踪剂摄取减少（UR=1.51±0.24）。结论 IgG4相关性疾病的眼部病变具有较典型的临床特征,泪腺弥漫性增大为眼眶MRI最常见表现,SRS能客观反映受累眼眶的免疫活动程度,对临床疗效评价有较好的价值。 （眼科,2015, 24： 309-312）       

Adjunctive Orbital Radiotherapy for Ocular Adnexal IgG4-related Disease: Preliminary Experience in Patients Refractory or Intolerant to Corticosteroid Therapy

Abstract

Purpose: To present the clinical outcomes of combined orbital radiotherapy and systemic corticosteroid for patients with refractory ocular adnexal IgG4-related disease.

Methods: We retrospectively reviewed 3 patients with histopathologically confirmed ocular adnexal IgG4-related disease who had been refractory or intolerant to corticosteroid therapy and treated with adjunctive orbital radiotherapy (2000 cGy; 10 fractions). Clinical improvement was assessed by monitoring the patient's ability to taper corticosteroid to discontinuation and by follow-up radiologic examination.

Results: All 3 patients had a favorable response to adjunctive radiotherapy with improvement of the clinical symptoms and radiologic abnormalities. Systemic corticosteroid was tapered and discontinued in all patients successfully. There were no adverse effects of treatment or recurrence after a mean follow-up of 19 months.

Conclusion: Adjunctive radiotherapy can help to achieve stable disease and cessation of systemic corticosteroid in patients with refractory ocular adnexal IgG4-related disease.
