Jul 10, 2022 · Here, we report that several months after the second vaccination, SARS-CoV-2-specific antibodies were increasingly composed of non-inflammatory IgG2 and particularly IgG4, which were further boosted by a third mRNA vaccination and/or SARS-CoV-2 variant breakthrough infections. The pathogenesis, clinical manifestations, diagnosis, and differential diagnosis of IgG4-RD are presented in detail separately, as is the treatment of type 1 AIP and IgG4-related sclerosing cholangitis. It has various normal functions in the body, but in IgG4-related disease, immune cells that produce IgG4, along with other related cells, accumulate abnormally in certain organs and damage them.

IgG4-related disease (IgG4-RD), formerly known as IgG4-related systemic disease, is a chronic inflammatory condition characterized by tissue infiltration with lymphocytes and IgG4 -secreting plasma cells, various degrees of fibrosis (scarring) and a usually prompt response to oral steroids. There was no significant difference in clinical features and outcomes between groups, with the exception of older age and greater pancreas involvement in IgG4-related patients.

Dec 5, 2025 · Learn about IgG4-Related Disease, its causes, symptoms, organs affected, diagnosis, and treatment options. Therefore, we aimed to evaluate the diagnostic value of gene expression analysis to differentiate orbital autoimmune diseases and Ten patients were classified as IgG4-related and 25 as non-IgG4-related. These conditions, where the body's immune system mistakenly attacks its own cells, affect a range of organs and systems within the body. Understand risk factors, management & prognosis.

Dec 15, 2017 · Background: Hepatic inflammatory pseudotumor (IPT) is classified into 2 types based on IgG4 stain: IgG4-related and non-IgG4-related; the two types differ not only in their pathological characteristics, but also in the clinical features. This article provides a list of autoimmune diseases. Mar 1, 2024 · Granulomatosis with polyangiitis (GPA) is likely the most common mimicker of IgG4-RD in the orbit, particularly because in addition to some overlapping histopathologic and immunophenotypic features, GPA also quite frequently displays ophthalmic manifestations (about half of patients), either as ocular or ocular adnexal/orbital inflammatory Oct 1, 2020 · IgG4 antibodies are found in a range of different diseases, including IgG4-related diseases, allergy, cancer, rheumatoid arthritis, helminth infection and IgG4 autoimmune diseases, where they may be pathogenic or protective.
