IgG4-related sclerosing cholangitis (IgG4-SC) is a chronic inflammatory disorder that affects the biliary ducts within and outside the liver. This complex condition is characterized by the presence of progressive inflammation, fibrosis, and stricture formation which can lead to serious complications such as biliary obstruction, ductal destruction, cirrhosis, and in severe cases, liver failure.

Unlike primary sclerosing cholangitis, IgG4-SC is an autoimmune disorder. It involves the aberrant action of IgG4 antibodies, which mistakenly attack and damage the bile ducts. This results in the significant inflammation and scarring (fibrosis) that are hallmarks of this illness.

This disorder typically manifests in individuals in the sixth to seventh decades of life and shows a predilection for affecting males. Occasionally, it is associated with other immune-mediated conditions such as autoimmune pancreatitis, which frequently coexists with IgG4-SC.

Patients may experience symptoms akin to those observed in other conditions affecting the biliary tract, such as jaundice, unexplained weight loss, and abdominal discomfort. These symptoms can often mirror those found in primary sclerosing cholangitis or cholangiocarcinoma, making accurate diagnosis challenging.

To diagnose IgG4-SC, healthcare providers may employ a variety of investigative tools. Cholangiography—a specialized imaging technique to visualize the bile ducts—is integral to the evaluation process. Additionally, elevated serum levels of IgG4 antibodies can support the diagnosis, although they are not universally present in all affected individuals. Histological examination of biopsy specimens is crucial for confirming the diagnosis, as it reveals the distinctive cellular changes associated with this condition.

Treatment for IgG4-SC typically involves the use of corticosteroids, with prednisone being a commonly prescribed agent. These medications aim to reduce inflammation and prevent further damage to the bile ducts, with complete remission as the ultimate goal of therapy. In cases where corticosteroids are ineffective, other immunosuppressive agents such as rituximab may be considered to manage the disease.
