RATIONALE: Immunoglobulin G4-related disease (IgG4-RD) is a systemic condition involving various organs and vessels including the pancreas, bile duct, salivary glands, periorbital tissues, kidneys, lungs, lymph nodes, meninges, and aorta. Recently, some cases of IgG4-RD have been reported, in which only pulmonary lesions were present. It is not known whether IgG4-RD can be diagnosed on the basis of pulmonary lesions only, because increases in serum IgG4 levels and infiltration of IgG4-positive plasma cells into the lung tissue also occur in other inflammatory conditions...

IgG4-related disease (IgG4-RD) which is a protein disorder presented as a mass in the right carotid triangle in a 30 year male patient, who underwent battery of tests is described. The radiologist opined the mass as paraganglioma and the spindle shaped character of the mass also suggested neurogenic tumor in differential diagnosis. Reference to vascular surgeon also opined the same, and adviced for incisional biopsy. Histopathology report suggested IgG4-RD and immunochemistry confirmed the final diagnosis...

IgG4-related disease (IgG4-RD) is a rare form of autoimmune sclerosing disease, characterised by elevated serum IgG4 and tissue IgG4 levels, specific histopathological findings, multiorgan involvement and adequate response to glucocorticoid treatment. The low incidence and the heterogeneous nature of the disease has made consensus on diagnostic criteria for IgG4-RD difficult. Whether sclerosing mesenteritis (SM) is considered a manifestation of IgG4-RD is strongly debated. We present the case of a patient with a history of rheumatoid arthritis who presented with a calcified abdominal mass...

IgG4-related disease (IgG4-RD) is a systemic fibro-inflammatory disease. This disease may be associated with elevated serum and tissue IgG4 levels. Early treatment prevents fibrosis and organ damage. We retrospectively studied the clinicopathologic correlation and outcome of treatment in IgG4-RD. This single-center retrospective study was done using electronic records of patients subjected to assay of serum IgG4 levels in our laboratory by nephelometry. There were 473 patients with suspected IgG4-RD. Of them, 41 patients fulfilled comprehensive diagnostic criteria for IgG4-RD and 432 had diseases other than IgG4-RD...

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...

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 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...

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)...

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...

A 59-year-old man presented with multiple dark red erythemas with induration, anemia, and polyclonal hypergammaglobulinemia. A skin biopsy revealed the infiltration of lymphocytes and plasma cells and he was initially diagnosed with multicentric Castleman's disease (MCD). Glucocorticoid treatment was only partially effective. Four years later, the patient's bilateral lacrimal glands gradually became enlarged and a biopsy revealed dense lymphocyte and plasma cell infiltration with an IgG4+/IgG+ plasma cell ratio of 70%...

PURPOSE: Immunoglobulin G4-related disease (IgG4-RD) is a relatively newly defined disease entity that refers to a group of immune-mediated disorders that have certain histopathologic, serologic, and clinical features in common. IgG4-RD is often associated with elevated serum IgG4. The discovery of IgG4-RD highlights the scarcity of literature examining elevations in other IgG subclasses and their potential associations to disease. In this retrospective chart review study, we aim to address that gap, by exploring disease associations in patients with isolated IgG subclass elevations...

BACKGROUND: IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory disorder that can affect most organs. To date, there have been no detailed assessments of pulmonary function in patients with IgG4-RD. In this study, we investigated pulmonary function in IgG4-RD patients and evaluated the value of pulmonary function tests (PFTs) in diagnosing IgG4-related respiratory disease (IgG4-RRD). METHODS: This was a retrospective study of 17 patients with IgG4-RD...

A 48-year-old man was admitted for evaluation of abnormal shadows on chest radiograph. Chest computed tomography (CT) showed cysts, nodules, and cervical and axillary lymphadenopathies. Elevated serum levels of IgG4 and interleukin (IL)-6 suggested IgG4-related disease (IgG4-RD) or multicentric Castleman's disease (MCD). Histologic findings of the cervical lymph node and right lung S(6) biopsies revealed numerous IgG4-positive plasma cells. Although CT findings of the lungs were atypical for IgG4-RD, consistent histologic findings, clinical symptoms, and laboratory data made us conclude IgG4-RD...
