Hypertriglyceridemia Induced Pancreatitis Due to Brentuximab Therapy: First Case Report

Brentuximab vedotin is used for relapsed classical Hodgkin’s lymphoma and mature T-cell lymphomas. We present a unique case of severe hypertriglyceridemia after one dose of single-agent brentuximab therapy. A Middle-Eastern male with a history of primary progressive cutaneous gamma/delta T-cell lymphoma was started on single-agent brentuximab vedotin therapy. Two weeks after single dose brentuximab therapy, he complained of severe epigastric pain, nausea, vomiting and was admitted to the intensive care unit with acute pancreatitis. Physical examination revealed an acutely ill patient with abdominal tenderness and laboratory data showed triglyceride levels of 3175 mg/dL, glycated hemoglobin (HbA1C) 9%, lipase 145 U/L and glucose 594 mg/dL. Computed tomography scan of the abdomen and pelvis confirmed acute interstitial pancreatitis. With medical management patient triglyceride levels decreased and the patient improved. This is the first case report in literature depicting, brentuximab induced hypertriglyceridemia leading to acute pancreatitis. It is a serious complication and can be lethal. Therefore, it is critical to maintain a high index of suspicion for hypertriglyceridemia induced pancreatitis after single dose brentuximab therapy.
