What antibodies are typically seen in high titers in patients with chronic active hepatitis?

In patients with chronic active hepatitis, the presence of high titers of anti-smooth muscle antibodies is indicative of an autoimmune component often associated with autoimmune hepatitis. These antibodies target smooth muscle, and their detection helps in the diagnosis of autoimmune hepatitis, where the immune system mistakenly attacks the liver tissue.

The presence of these antibodies correlates with liver inflammation and may lead to significant liver damage if left untreated. Anti-smooth muscle antibodies are commonly found in conjunction with other autoimmune markers, contributing to a broader profile that informs the diagnosis and management of the disease.

Other antibodies listed—such as anti-mitochondrial antibodies and anti-nuclear antibodies—are associated with different autoimmune conditions and liver diseases but are not specifically indicative of chronic active hepatitis in the same way that anti-smooth muscle antibodies are. Anti-thyroid antibodies pertain to thyroid dysfunctions and are unrelated to hepatic conditions directly.
