Ustekinumab-induced autoimmune hepatitis: a case report.

Ustekinumab is a fully human monoclonal antibody that binds to interleukin (IL)-12/23. Ustekinumab-related liver injury (UST) is rare. There is limited data available on the potential for ustekinumab-liver interaction.

[Alpha-fetoprotein-producing poorly differentiated gastric adenocarcinoma: hepatoid carcinoma?].

We report the case of a 42-Year-old man with a poorly differentiated gastric cancer revealed by a very high level of serum alpha-fetoprotein-protein, associated with liver metastasis, and treated by chemotherapy. We discuss the possible diagnosis of hepatoid carcinoma.

[Acute tubular necrosis with acute renal failure during the first month of treatment with 5-amino-salicylate (Pentasa(R))].

We report a case of acute tubular necrosis in a patient with Crohn's disease treated by 5-amino-salicylate (Pentasa(R)) since one month. Normalization of renal biological parameters occurred rapidly after treatment withdrawal. This case raises the question of the optimal modalities of monitoring of renal function during treatment with 5-amino-salicylate.
