Acute Pancreatitis Induced by Polatuzumab-Vedotin-Piiq in Combination With Bendamustine and Rituximab for Diffuse Large B-Cell Lymphoma

While alcohol and gallstones have been considered the most common causes of pancreatitis, we investigate two uncommon etiologies such as drug-induced and viral-induced. Pancreatitis, an inflammatory process, can lead to many complicated outcomes such as acute respiratory failure, sepsis, and death. Examining drug-induced pancreatitis poses a large challenge for physicians as majority of the data is extrapolated from case reports. This is made even more difficult for patients who are on large chemotherapeutic regimens which include multitude of drugs and various side effects. Besides patient medication regimens, other etiologies of pancreatitis must be ruled out such as viruses. We examine a case of a 48-year-old female undergoing treatment for diffuse large B-cell lymphoma with various chemotherapeutic agents and positive cultures for varicella zoster virus (VZV) presenting with diffuse epigastric abdominal pain.
