Therapeutic agents to inhibit tumour necrosis factor alpha (TNF-alpha) have dramatically improved the treatment options for patients with autoimmune diseases. Common side effects include an increased susceptibility towards infection. Hepatic side effects are less frequently observed. Elevated liver function tests, hyperbilirubinaemia reactivation of chronic viral hepatitis or even acute liver failure have been described. Some cases have exhibited an autoimmune phenotype with the emergence of autoantibodies and characteristic histological lesions. We report on three patients who received anti-TNF therapy for psoriasis and presented with elevated liver function tests in the further course. Histological and serum analysis revealed an autoimmune phenotype of liver injury. In light of the growing use of anti-TNF therapies, drug-induced liver injury (DILI) with an autoimmune phenotype is an important side effect. Since the pathophysiological mechanisms related to the autoimmune phenotype of liver injury during TNF-inhibition are not well understood, the cases detailed herein should help treating physicians to improve their understanding of the situation.
