In approximately 51–70% of people with this disease, serum Ig G4 concentrations are elevated during an acute phase. It is a relapsing–remitting disease associated with a tendency to mass forming, tissue-destructive lesions in multiple sites, with a characteristic histopathological appearance in whichever site is involved. Field of vision test plaquenil Hydroxychloroquine autophagy Stone characterized IgG4 as “kind of a wimpy antibody” incapable of driving the disease process because it is a noninflammatory immunoglobulin. This has led to speculation that IgG4 functions as what he termed an “antigen sink,” attempting to bind antigen at sites of inflammation. 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. IgG4-related disease is usually treated with systemic steroids like prednisone. Immunosuppressive medications azathioprine or mycophenolate mofetil and biologics rituximab or bortezomib may be used in those who don't respond to steroids or for longer-term management. Ig G4-related disease has been described as an indolent condition. Inflammation and the deposition of connective tissue in affected anatomical sites can lead to organ dysfunction, or even organ failure, if not treated.

INTRODUCTION IgG4-related disease IgG4-RD is an emerging systemic inflammatory disease involving nearly all organs eventually leading to fibrosis. Prompt and adequate treatment to prevent irreversible organ damage is therefore pivotal. To evaluate the treatment outcomes, we studied a well-defined cohort of patients with IgG4-RD. IgG4-related disease IgG4-RD is a systemic autoimmune disorder characterized by elevated serum immunoglobulin Ig G4 levels and tumorlike fibroinflammatory masses with distinctive histopathologic features that almost always include infiltrates of IgG4 + plasma cells. IgG4-related disease IgG4-RD is considered a systemic, chronic and inflammatory disorder that is characterized by the enlargement of involved organs, elevated levels of IgG4 and abundant infiltration of plasmacytes with IgG4 and fibrosis in involved organs.
