Autoimmune hepatitis with eosinophilic infiltration responsive to anti-interleukin-5 receptor treatment: a case report and literature review.

Inflammatory tissue damage plays a role in the onset, progression, and exacerbation of various chronic autoimmune and metabolic diseases such as autoimmune hepatitis. Here we present a case of autoimmune hepatitis with liver eosinophilic infiltrate in a severe eosinophilic asthma patient who failed conventional immunosuppressive treatment and showed improvement in gastrointestinal symptoms after anti-interleukin-5 receptor treatment. Our case highlights the potential role of eosinophils in initiating or worsening liver inflammation in autoimmune liver disease. The link between eosinophilic inflammation, barrier damage, and chronic autoimmune diseases should be considered in clinical practice. [ABSTRACT FROM AUTHOR]
