6-Mercaptopurine-induced Recurrent Acute Pancreatitis in Children With Acute Lymphoblastic Leukemia/LymphomaHalalsheh, Hadeel MD; Bazzeh, Faiha MD; Alkayed, Khaldoun MD; Salami, Khadra MD; Madanat, Faris MDJournal of Pediatric Hematology/Oncology: August 2013 - Volume 35 - Issue 6 - p 470–472 doi: 10.1097/MPH.0b013e318271c92f Clinical and Laboratory Observations Abstract Author Information Two children with acute lymphoblastic leukemia/lymphoma developed recurrent acute pancreatitis during treatment; the etiology was presumed to be secondary to 6-mercaptopurine (6MP). Both had no further attacks after discontinuation of 6MP. Acute pancreatitis secondary to 6MP is extremely rare in acute leukemia/lymphoma although it has been reported in patients with other conditions like inflammatory bowel disease; the reason for this difference is not clearly understood.
