Biologic therapy has revolutionized the management of chronic inflammatory diseases, including inflammatory bowel disease (IBD). Before the initiation of therapy, it is critical to rule out prior infection of chronic hepatitis B virus (HBV) and tuberculosis (TB). However, screening for human immunodeficiency virus (HIV) is not as routinely completed. We present a case of a 56-year-old male on ustekinumab for the management of Crohn's disease, found to have undiagnosed human immunodeficiency virus (HIV) with progression to acquired immunodeficiency syndrome (AIDS).

We present a rare case in which malignant catatonia led to acute liver failure (ALF). A 19-year-old male was admitted for psychosis and developed ALF with a peak aspartate aminotransferase and alanine aminotransferase of 5,728 U/L and 7,735 U/L, respectively, and a peak international normalized ratio of 7.1. Liver biopsy showed significant confluent necrosis involving >70% of the liver tissue. He was listed for a liver transplant but was ultimately taken off of because of significant improvement with treatment by Nacetylcysteine infusion. Through our research, we found that symptoms of hepatitis can be seen with psychotic disorders, but ALF is rare.
