What type of pancreatitis is associated with the presence of IgG4 secreting plasma cells?
IgG4-related sclerosing cholangitis is commonly associated with type I autoimmune pancreatitis39. If untreated, it can progress to end-stage liver disease and is extremely difficult to differentiate from primary sclerosing cholangitis. The histology includes obliterative phlebitis and transmural fibrosis.

What is the function of IgG4?

IgG4 antibodies possess exclusive structural and functional characteristics suggesting anti-inflammatory and tolerance-inducing effects.
How do you test for IgG4?
No single test can be used to diagnose IgG4-RD; instead, diagnosis depends on a combination of medical information, including history, physical findings, imaging, and laboratory results, supported by histopathology.

Can IgG4 be cured?
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.
