IgG4 related lung disease

Kyoko Otani, Dai Inoue, Tomoo Itoh, Yoh Zen
AIMS: The diagnosis of IgG4-related disease (IgG4-RD) requires a multidisciplinary approach, in which histology plays an important role. Although a diagnosis was previously established using surgically resected specimens, there is increasing clinical demand to diagnose this systemic condition by biopsies. The present study aimed to elucidate how useful transbronchial lung biopsies (TBLBs) are for this diagnostic purpose. METHODS AND RESULTS: The study cohort consisted of 20 consecutive patients diagnosed with IgG4-RD in other organs who underwent TBLBs for potential pulmonary involvement...

IgG4-related disease (IgG4-RD) is a chronic and systemic disease that can involve multiple organs. The most commonly involved organs include the salivary glands, orbital adnexal structures, paranasal sinus, thyroid, lungs, breasts, aorta, pancreas, biliary ducts, kidneys, retroperitoneum, lymph nodes, prostate, pituitary, and endocranium. Due to increased disease research, several new site-specific nuances of IgG4-RD have been described. The authors have reviewed the recent literature and briefly summarize the infrequent organ involvement of IgG4-RD...

The present study aimed to compare clinicopathologic features between idiopathic multicentric Castleman's disease (n=22) and IgG4-related disease (n=26). Histology was analyzed using lymph node and lung biopsies. The expression of IL-6 mRNA in tissue was also examined by in situ hybridization and real-time PCR. Patients with idiopathic multicentric Castleman's disease were significantly younger than those with IgG4-related disease (p<0.001). Splenomegaly was observed in only idiopathic multicentric Castleman's disease (p=0...

IgG4-related disease is an inflammatory condition characterized by high levels of IgG4. It affects salivary and lacrimal glands, pancreas, lymph nodes, lungs or kidney. The diagnosis is based on identifying a histological pattern with a dense lymphocyte and plasmacyte infiltration, focal fibrosis or phlebitis, finding more than 10 IgG4 positive cells per high power field and/or IgG4/IgG ratio in plasma higher than 40%. We present a patient with Mikulicz's disease who meets histological findings required for the diagnosis of IgG4 related disease...

Immunoglobulin G4-related disease is a rare immune-mediated condition that often causes serious diagnostic problems. Symptoms are unspecific, and several organs can be involved. To date, IgG4-related lung disease has seldom been reported in literature. Nevertheless, a variety of pulmonary involvement has been described, which can mimic malignancy. The gold standard for the diagnosis is the identification of typical histopathological features, even if diagnostic biomarker such as serum IgG4 concentration can be an indicator for a more aggressive course of the disease...

OBJECTIVE: Serum immunoglobulin (Ig) G4 elevation has been associated with several pathological conditions other than IgG4-related disease (IgG4-RD). In cystic fibrosis (CF), an elevation of specific IgG4 has been associated with colonization and infection by Pseudomonas aeruginosa. IgG4 elevation may be a marker of chronic infection or inflammatory stimulation. The aim of this study was to explore the prevalence of elevated IgG4 levels in CF and its correlation with the major clinical and microbiological features found in CF patients...

IgG4-related diseases represent a heterogeneous group of conditions characterised by elevated serum IgG4 levels and fibrotic or sclerosing changes in the affected organs or systems accompanied by IgG4-positive plasma cells. A disease associated with IgG4 may affect virtually any organ - salivary glands, periorbital tissue, kidneys, lungs, meninges, aorta, prostate, pericardium or skin. Histopathological findings are uniform, characterised by a major lymphoplasmocytic infiltrate and the presence of IgG4-producing plasma cells, irrespective of the affected site...

In common variable immunodeficiency, lung manifestations are related to different mechanisms: recurrent pneumonias due to encapsulated bacteria responsible for diffuse bronchiectasis, diffuse infiltrative pneumonia with various patterns, and lymphomas, mostly B cell extranodal non-Hodgkin type. The diagnosis relies on significant serum Ig deficiency and the exclusion of any primary or secondary cause. Histopathology may be needed. Immunoglobulin (IgG) replacement is crucial to prevent infections and bronchiectasis...

Immunoglobulin G4 (IgG4)-related disease (IgG4-RD) is an immune-mediated condition characterized by infiltration of the involved organs by IgG4-bearing plasma cells. The prevalence of autoimmune diseases, associated with or occurring in patients with human immunodeficiency virus (HIV) infection, has been increasing. We describe a 58-year-old man with an undiagnosed HIV infection, which presented as chronic cervical lymphadenopathy with an elevated serum IgG4 and a very high IgE. Histologically, lymph nodes showed expanded sinusoids and burnt-out germinal centers with increased plasmacytic infiltration and collagen fiber deposition...

Immunoglobulin G4 (IgG4)-related systemic disease (IgG4-RSD) is a new systemic entity associated with autoimmune pancreatitis (AIP). Other organ involvements take the form of sclerosing cholangitis, sclerosing cholecystitis, sclerosing sialadenitis, retroperitoneal fibrosis, and interstitial nephritis. Recently, lung diseases related to IgG4 have been described to occur with or without other organ involvement. These diseases include interstitial lung disease (ILD), pulmonary inflammatory pseudotumor, and lymphomatoid granulomatosis...

As an idiopathic interstitial pneumonia, desquamative interstitial pneumonia (DIP) is an uncommon form of interstitial lung disease and is considered to be a smoking- or dust inhalation-related interstitial pneumonia in the majority of cases. However, the details regarding immunoglobulin G4 (IgG4)-related lung disease remain unclear and controversial. We herein report the first case of DIP complicated with IgG4-related lung disease. Even if a patient has a smoking history, we emphasize the importance of exploring the association between DIP and IgG4-related lung disease to clarify the pathogenesis of these two disorders...

Lung cancer is the leading cause of cancer-related death worldwide. The most common type, non-small cell lung cancer (NSCLC), is further divided into two main types, squamous cell and non-squamous cell (which includes adenocarcinoma). Nivolumab, a fully human IgG4 programmed death-1 immune checkpoint inhibitor antibody, has shown not only an overall survival advantage when compared to docetaxel, but also a relatively good side-effect profile among patients with previously treated advanced squamous and non-squamous NSCLC...
