Immunoglobulin G4-related disease: autoimmune pancreatitis and extrapancreatic manifestations*

We present a case of immunoglobulin G4 (IgG4)-related disease with pancreatic and extrapancreatic involvement, including the biliary and renal systems. Given the importance of imaging methods for the diagnosis of IgG4-related disease and its differentiation from pancreatic adenocarcinoma, we emphasize important abdominal computed tomography and magnetic resonance imaging findings related to thi...

Hilar cholangiocarcinoma associated with immunoglobulin G4‐positive plasma cells and elevated serum immunoglobulin G4 levels

Immunoglobulin G4 (IgG4)-related disease is a fibroinflammatory systemic disorder with multiorgan involvement. Proximal bile duct involvement results in IgG4-related sclerosing cholangitis, which is characterized by a lymphoplasmacytic infiltrate with abundant IgG4-positive plasma cells and fibrosis. Differentiating between cholangiocarcinoma and IgG4-sclerosing cholangitis can present a diagno...

Experimental neonatal colibacillosis in cows: immunoglobin classes involved in protection.

Pregnant cows were vaccinated with one of four vaccine preparations to induce passive immunity in their offspring against a homologous oral challenge with Escherichia coli strain B-44. Quantitative assays of specific antibody in colostral whey from both immunized and nonimmunized dams revealed that immunoglobulin G, immunoglobulin A (IgA), and immunoglobulin M (IgM) with anti-O (somatic) activi...
