AIM: Several studies have implicated increased risk of malignancy in patients with immunoglobulin G4-related disease (IgG4-RD). Hence, we first evaluated the risk and the type of malignancy in Korean IgG4-RD patients. METHOD: Clinical and laboratory results of patients fulfilling the comprehensive diagnostic criteria for IgG4-RD were retrospectively collected between January 2006 and November 2015. One hundred and eighteen patients were included, and 35 were classified as having definite, 83 as possible/probable IgG4-RD...

Patients with IgG4-related disease (IgG4-RD) often have elevated serum IgG4 levels. Here, we aimed to evaluate the diagnostic performances of elevated serum IgG4 concentration and IgG4/IgG ratio for IgG4-RD. We retrospectively analyzed 1381 patients subjected to serum IgG subclass testing to differentiate IgG4-RD from other diseases at Peking University People's Hospital from 2012 to 2016. This sample included 133 IgG4-RD patients and 1248 non-IgG4-RD patients. Serum IgG subclass concentrations were measured using Siemens reagents...

We present the case of a 55-year-old woman admitted for a coronary artery bypass operation because of three-vessel coronary artery disease based on angiographic findings and clinical symptoms. Unexpected intraoperative findings with diffuse tissue thickening of the ascending aorta and coronary arteries indicated an alternate pathogenesis rather than coronary artery atherosclerosis. Histopathologic findings and clinical evaluation could confirm IgG4-related disease (IgG4-RD). IgG4-RD is a newly recognized fibroinflammatory condition that can present in a variety of organs and is characterized by common histopathologic features...

Autoimmune pancreatitis (AIP) is a rare form of chronic pancreatitis, classified into 2 subtypes - AIP type 1 and AIP type 2. We present a case of a 31-years-old female admitted to our institution with upper abdominal pain and obstructive jaundice. Endoscopic retrograde cholangiopancreatoscopy (ERCP) revealed stenosis of intrapancreatic distal bile duct. Diffuse parenchymal enlargement and typical features of AIP were shown by computed tomography (CT) and endoscopic ultrasonography (EUS). The patient´s serum IgG4 was elevated at 3...

IgG4-related sclerosing disease of the larynx (IgG4-SD) is a recently described immunodependent systemic pathology characterized by diffusive or focal inflammatory infiltration of the affected organs and tissues by plasma cells expressing IgG4; it is accompanied by the subsequent development of obliterative phlebitis and fibrosclerosis associated with the increase of the serum IgG4 level. According to the recently published materials, the disease can also develop in the respiratory system. The present article describes the first documented case of IgG4-related sclerosing disease with the isolated lesion of the larynx...

RATIONALE: IgG4-related disease (IgG4-RD) is a newly recognized systemic disease. The typical pathological finding in the kidney is abundant IgG4-positive plasma cell infiltration with characteristic storiform fibrosis in the interstitium. Antibodies of the IgG4 subclass have been linked to certain autoimmune diseases including antiproteinase 3 (PR3) anti-neutrophil cytoplasmic antibody (ANCA) of the IgG4 subclass. Here, we report a rare case of kidney injury with concurrent typical IgG4-related tubulointerstitial nephritis and IgG4 subclass of myeloperoxidase (MPO) ANCA-positive necrotizing crescentic glomerulonephritis...

PURPOSE: To investigate the change of serum IgG4 concentrations correlated with clinical evolution in patients with ocular adnexal marginal zone B cell lymphoma associated with IgG4-related ophthalmic disease (IgG4-ROD). METHODS: Three consecutive patients with histopathologically confirmed ocular adnexal marginal zone B cell lymphoma associated with IgG4-ROD were evaluated. Two patients received radiotherapy and 1 patient received steroid therapy. Treatment outcome was evaluated by clinical symptoms, radiologic examination, and change of serum IgG4 level in these patients...

IgG4 related thoracic aortitis is a recent addition to the differential diagnosis for inflammatory aortic disease - a condition which is often underappreciated until complications arise such as aneurysmal formation or aortic dissection. Currently, IgG4 aortitis remains a post-surgical diagnosis reliant on positive immunohistochemistry findings. Management is guided by the extent of disease involvement, which can be gauged by serum IgG4 levels and radiological findings. Options include surgical resection, corticosteroid therapy and steroid-sparing agents to prevent relapses...

PURPOSE OF REVIEW: IgG4-related disease (IgG4-RD) is an immune-mediated disease of unknown cause. It predominantly affects the biliary tract [IgG4-associated cholangitis (IAC)] and pancreas [autoimmune pancreatitis (AIP)] of mostly elderly men. Accurate diagnostic tests are lacking. Patients benefit from predniso(lo)ne treatment. However, disease relapse is often seen. This review will address pathophysiological aspects and advances in diagnostic and therapeutic strategies. RECENT FINDINGS: The role of IgG1 and IgG4 in the pathophysiology of IgG4-RD was studied in mice which showed more intense organ damage of pancreas and salivary glands when IgG1 rather than IgG4 of patients with IgG4-RD was injected...

Pathologists are likely to encounter IgG4-related disease in several organ systems. This article focuses on helping pathologists diagnose IgG4-related disease in the hepatobiliary system. Missing the diagnosis can result in unnecessary organ damage and/or unnecessary surgical and cancer therapy. In the liver, tumefactive lesion(s) involving the bile ducts with storiform fibrosis and an IgG4-enriched lymphoplasmacytic infiltrate are highly concerning for IgG4-related disease. The recent identification of oligoclonal populations of T cells and B cells in IgG4-related disease may lead to molecular tests, new therapeutics, and a greater mechanistic understanding of the disease...

Large-vessel vasculitis (LVV) is a group of diseases mainly comprised of giant-cell arteritis (GCA), Takayasu arteritis, and a series of rare diseases like Behçet's disease, IgG4-related disease, infectious aortitis, and other unfrequent entities. Besides clinical and laboratory features, Doppler sonography (DS) can assist in establishing the diagnosis. Its diagnostic sensitivity has been evaluated in various studies, most of them, however, in temporal arteritis (TA) respectively in LVV with involvement of the temporal artery...

IgG4-related disease is a systemic, inflammatory disorder typically involving multiple organ systems. Several eponymous conditions described previously in the clinical and radiology literature are now recognised to be part of the IgG4-related disease spectrum. This includes multiple manifestations in the head and neck region, which are the subject of this review. Imaging can occasionally suggest the specific diagnosis of IgG4 disease. More commonly, it will be included in a limited differential diagnosis that requires clarification with the aid of image-guided biopsy...

Non-infectious aortitis may be caused by several distinct systemic rheumatologic diseases. In some patients, aortitis is identified either pathologically or radiologically in the absence of clinical evidence of a systemic vasculitis. By consensus nomenclature, such cases are referred to as clinically isolated aortitis (CIA). Some systemic disorders may initially present as CIA including giant cell arteritis (GCA), IgG4-related disease, infectious aortitis, and granulomatosis with polyangiitis. CIA most commonly occurs in women of European descent over the age of 50 and, thus, mirrors the gender, age, and geographic distribution of GCA...

The inflammatory pseudotumour of the head and neck is a benign lesion, extremely rare outside the cranial orbits. A case is presented of an inflammatory pseudotumour not associated with the IgG4-related disease. The pseudotumour was found as a solitary mass in the infratemporal fossa of a young woman who complained of otalgia and hearing loss. A clear image of the lesion was obtained using an (18)F-fluoro-deoxy-glucose ((18)F-FDG) PET. After the histopathological diagnosis, and treatment with corticosteroids, a second (18)F-FDG PET was performed...

IgG4-related disease is a relatively newly described entity with findings that historically have been confused with a variety of other diseases with markedly different treatments and prognoses, including Sjogren's syndrome and MALT lymphoma. We present a case of IgG4-related disease of the salivary glands and review the literature on sonographic findings of IgG4-related disease. By connecting sonographic features of IgG4 disease with common ancillary features of IgG4 disease in other sites (pancreas, hilar lymph nodes, biliary tree, thyroid, and retroperitoneum), radiologists can play a pivotal role in the early diagnosis and identification of IgG4-related disease...

Vascular and/or perivascular involvements of sclerotic inflammation (perivasculitis) are a complication of immunoglobulin G4-related disease (IgG4-RD). We sought to examine clinical manifestations of perivasculitis by computed tomography (CT) in patients with elevated serum IgG4 levels, and then to evaluate some potential predictors of perivasculitis in definite IgG4-RD patients. From a database of patients with serum IgG4 measurements, we selected 81 patients with elevated serum IgG4 levels (≥135 mg/dl)...

A 76-year-old man had a hypopituitarism including adrenal insufficiency, hypogonadism and hypothyroidism. Based on various findings including the swelling of the pituitary gland, increase of serum IgG4 level and abundant IgG4-positive plasma cell infiltration in immunostaining of the pituitary gland, we diagnosed this subject as IgG4-related hypophysitis. In general, a high-dose glucocorticoid treatment is effective for IgG4-related disease. His clinical symptom, laboratory data and adrenal insufficiency were almost improved without any therapy...

Primary sclerosing cholangitis (PSC) is a disease of the biliary tract, which has been documented in the literature since 1867. This disease has a strong predilection for affecting men and can be seen in individuals as young as 2 years of age. PSC has a strong associated with inflammatory bowel disease, more commonly with ulcerative colitis, and is also part of the clinical spectrum of IgG4-related diseases. Small-duct PSC, a variant of PSC, also has an association with inflammatory bowel disease. The exact pathogenesis of PSC is not well understood at present, however, is likely a combination of a genetic predisposition with alteration of the molecular structure of the gut...

IgG4-related disease (IgG4-RD) is a recently recognized disease entity characterized by high serum IgG4 concentrations and infiltration of IgG4+ plasma cells with hyperplastic ectopic germinal centres at affected sites. Although the underlying immune mechanism of this disease remains unclear, T cells are abundantly present at affected sites and key players in IgG4-RD pathogenesis. The role of T cell subsets has been investigated thoroughly in this disease. Recent advances in this field have clarified the importance of T follicular helper cells...
