IgG4-related disease (IgG4-RD) is a rare, chronic inflammatory condition that may involve nearly every organ system. Originally identified as a cause of autoimmune pancreatitis, its characteristic histological and clinical features have been found in a wide variety of inflammatory presentations, including the eye and orbit. Here we describe an example of a case of IgG4-RD initially presenting as scleritis and vitritis, with further progression to multifocal bilateral orbital involvement. Tissue biopsy of an orbital mass was highly characteristic of IgG4-RD histology and a rapid clinical response to corticosteroids was observed...

OBJECTIVE: Immunoglobulin (Ig) G4-related aortic aneurysms (IgG4-AAs) are a special aortic aneurysm among IgG4-related diseases (IgG4-RDs), which are inflammatory and fibrous conditions characterized by tumorous swelling of affected organs and high serum IgG4 concentrations. Recently, IgG4-RD pathogenesis was shown to be associated with T-helper-2 (Th2) and regulatory T (Treg) dominant cytokine production, such as interleukin (IL)-4, IL-10, and IL-13. IL-6 is a key proinflammatory cytokine contributing to lymphocyte and plasmacyte maturation and to atherosclerosis and aneurysm development...

BACKGROUND: In the Netherlands, acellular pertussis vaccines replaced the more reactogenic whole-cell pertussis vaccines. This replacement in the primary immunization schedule of infants coincided with a significant increase in pronounced local adverse events (AEs) in 4 years old children shortly after the administration of a fifth diphtheria, tetanus, acellular pertussis and inactivated polio (DTaP-IPV) vaccine. The objective of this study was to investigate possible differences in vaccine antigen-specific immune responses between children with and without a pronounced local AE after the fifth DTaP-IPV vaccination...

Autoantibodies against ion channels are the cause of numerous neurologic autoimmune disorders. Frequently, such pathogenic autoantibodies have a restricted epitope-specificity. In such cases, competing antibody formats devoid of pathogenic effector functions (blocker antibodies) have the potential to treat disease by displacing autoantibodies from their target. Here, we have used a model of the neuromuscular autoimmune disease myasthenia gravis in rhesus monkeys (Macaca mulatta) to test the therapeutic potential of a new blocker antibody: MG was induced by passive transfer of pathogenic acetylcholine receptor-specific monoclonal antibody IgG1-637...

Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the oesophagus. Recognized as a distinct entity only two decades ago, the emergence of the disease along with the availability of new technologies has rapidly opened new research avenues and outlined the main features of the pathogenesis of EoE. Yet, each advance in our understanding of the disease has raised new questions about the previous consensus. Currently, new subsets of the disease challenge our diagnostic criteria. For instance, it was believed that EoE did not respond to proton pump inhibitor (PPI) therapy; however, it has now been shown that a substantial proportion of EoE patients indeed respond to PPIs...

IgG4-related disease is a recently discovered pathological entity, histologically characterised by fibrosis and IgG4-positive plasma cell infiltration. This condition may virtually involve every site of the organism, with a various range of clinical presentations. The most commonly affected organ is the pancreatic gland, but it can also involve the biliary tract, salivary and lacrimal glands, kidneys, orbital tissues, lymph nodes, lungs and many others. More recently, IgG4-related disease has been demonstrated to involve, in rare cases, also the central nervous system, with a pattern mainly characterised by hypertrophic pachymeningitis...

RATIONALE: IgG4-related disease is a newly recognized fibroinflammatory disorder, characterized by tumefactive lesions, storiform fibrosis and IgG4-positive plasma cells infiltration. IgG4-related sclerosing cholangitis (IgG4-SC) is the most common extrapancreatic manifestation of IgG4-related disease, but it is frequently associated with autoimmune pancreatitis(AIP). Only few case was reported to be diagnosed with IgG4-SC in the absence of AIP, with a striking male preponderance. Here we report a female case of isolated IgG4 related sclerosing cholangitis mimicking cholangiocarcinoma...

In South Africa few studies have examined the effects of the overlap of HIV and helminth infections on nutritional status. This cross-sectional study investigated the interaction between HIV and intestinal helminths coinfection with nutritional status among KwaZulu-Natal adults. Participants were recruited from a comprehensive primary health care clinic and stratified based on their HIV, stool parasitology, IgE, and IgG4 results into four groups: the uninfected, HIV infected, helminth infected, and HIV-helminth coinfected groups...

We herein report a case of Rosai-Dorfman disease (RDD) overlapping with IgG4-related disease (IgG4-RD), which presented as diffuse interstitial lung disease with a perilymphatic pattern, followed by submandibular gland and eyelid swelling. The pathological findings of the submandibular gland biopsy specimen were indicative of IgG4-RD alone. We diagnosed the patient with RDD with overlapping IgG4-RD. However, the optimal method for differentiating between these two entities is still controversial. It is important that clinicians are aware that RDD should be included in the differential diagnoses of diffuse interstitial lung disease with a perilymphatic pattern and that RDD can overlap with IgG4-RD...

Neutralizing antibodies may affect interferon (IFN)-β treatment efficacy, but mechanisms of neutralizing anti-drug antibody (ADA) evolution are not fully elucidated. We investigated the relationship between ADA titers, IgG subclass profile, and binding affinity with the development and persistency of neutralizing ADA in relapsing-remitting multiple sclerosis (MS) patients treated with subcutaneous IFN-β. A total of 94 patients, who had blood sampling at months 6, 12, 24, and 36 during IFN-β therapy, were included into this retrospective study and stratified to the following: non-neutralizing, transient, and persistent neutralizing ADA status...

Allergen immunotherapy (AIT) is an immune modulating treatment for allergic diseases. Although highly effective, some patients do not respond to the treatment. To date there are no surrogate biomarkers that are predictive of the clinical response to AIT. More and more is known about the underlying immunological mechanism involved in AIT. Through modulation of both innate and adaptive immune responses, involving reduced ILC2 and enhanced Treg and Breg induction and functionality, along with induction of IgG4 antibody production which have the capacity to inhibit both allergen-induced basophil responsiveness and CD23-mediated IgE-facilitated allergen presentation, the result is an immune skewing towards a more balanced Type I response...

Pachymeningitis is a fibrosing and inflammatory process, which involves the dura mater. Some pachymeningitis are cranial and induce headaches and cranial nerve palsies. Others are spinal and responsible for nerve roots or spinal cord compression. MRI shows contrast enhancement thickening of the dura mater. Etiologies are infectious (syphilis, tuberculosis, etc.) or inflammatory (sarcoidosis, granulomatosis with polyangiitis, IgG4-related disease, idiopathic). Corticosteroids are the main treatment. The use of immunosuppressive drugs or rituximab is yet to be determined and probably adapted to each etiology...

Submandibular gland is an important human function organ. With the wide application of sialoendoscope and new understanding of IgG4 related sialadenitis, a lot of submandibular glands which were previously considered to be removed are preserved. However, some submandibular glands which might be preserved are still unfortunately sacrificed. Therefore, we advocate the popularization and promotion of new knowledge and techniques and should pay more attention to the protection of the function organ of submandibular gland...

BACKGROUND AND OBJECTIVES: Helicobacter pylori (H.pylori) plasminogen binding protein (PBP) has been proposed as an antigen triggering autoimmune pancreatitis (AIP), the pancreatic manifestation of IgG4-related disease (IgG4-RD). We investigated exposure to H. pylori infection, cytokine response and immunological memory to H. pylori PBP in a prospective IgG4-RD cohort in the UK. METHODS: Clinical and endoscopic evidence of peptic ulceration, serological H. pylori exposure and serum IgG4 levels were obtained in 55 IgG4-RD patients and 52 disease controls (DC) with autoimmune or inflammatory conditions with an elevated serum IgG4...

Dynamics of three MET antibody constructs (IgG1, IgG2, and IgG4) and the IgG4-MET antigen complex was investigated by creating their atomic models with an integrative experimental and computational approach. In particular, we used two-dimensional (2D) Electron Microscopy (EM) images, image class averaging, homology modeling, Rapidly exploring Random Tree (RRT) structure sampling, and fitting of models to images, to find the relative orientations of antibody domains that are consistent with the EM images. We revealed that the conformational preferences of the constructs depend on the extent of the hinge flexibility...

IgG4 related disease is a recently recognized chronic fibrotic, inflammatory condition, caused by infiltrating IgG4 positive plasma cells that can cause tumor like disease in almost any organ in the body. Typical histopathology is lymphoplasmocytic infiltration of IgG4 positive cells, storiform fibrosis and obliterative phlebitis. Glucocorticoids alone or in combination with B-cell depletion with rituximab causes often good, lasting response. We present here a lady with recurrent lung infiltration that simulated pneumonia and later tumor of the lung...
