Igg4 Related Sclerosing Disease
Igg4 related sclerosing disease. An elevated serum titer of immunoglobulin G4 IgG4 the least common 3 to 6 of the 4 subclasses of IgG is a surrogate marker for the recently characterized IgG4-related sclerosing disease. IgG4 related disease IgG4-RD is an immune mediated condition presenting with mass forming lesions that lead to permanent organ injury and death if left untreated. 23 51 81-84 Biliary tract disease may also be seen in some cases without pancreatic involvement.
Immunoglobulin G4 IgG4-related disease is a systemic autoimmune disease with pancreatic and extrapancreatic abdominal manifestations. The extrapancreatic organs that may be involved. Activated regulatory T cells secrete transforming growth factor-β which is responsible for the fibrosis seen in IgG4-related disease 8.
This report describes 2 cases with skin involvement a feature not well. IgG4-related sclerosing cholangitis A form of sclerosing cholangitis that is clinically distinct from primary sclerosing cholangitis may occur as part of the IgG4-RD. IgG4-related disease unifies a variety of seemingly disparate conditions that share a common pathophysiology conditions now considered part of IgG4-related disease include type 1 autoimmune pancreatitis lymphoplasmacytic sclerosing pancreatitis eosinophilic angiocentric fibrosis affecting orbits and upper respiratory tract.
IgG4-related sclerosing disease and suggested that autoimmune pancreatitis is in fact a part of that disease spectrum. This IgG4-related sclerosing cholangitis is the most common extrapancreatic manifestation of type 1 AIP IgG4-related present in over 70 percent of such patients. Based on histological and immunohistochemical examination of various organs of patients with autoimmune pancreatitis AIP a novel clinicopathological entity of IgG4-related sclerosing disease has been proposed.
Immunosuppressive medications azathioprine or mycophenolate mofetil and biologics rituximab or bortezomib may be used in those who dont respond to steroids or for longer-term management. IgG4-related disease is usually treated with systemic steroids like prednisone.

IgG4-related sclerosing disease is a syndrome characterized by the involvement of a wide variety of tissues by lymphoplasmacytic infiltrates and sclerosis elevated serum IgG4 titer and increased IgG4 plasma cells in tissues. It is a multi-organ fibro-inflammatory condition with tumefactive lesions of unknown etiolog.
