Asparaginase (ASP) and steroids are a main part of treatment for ALL, in both front-line and relapse setting. It is known, that ASP can cause several toxicities such as hypersensitivity, pancreatitis, as well as severe lipid and coagulation disturbances. Administered steroids can result in diabetes, obesity, hyponatremia and also mild hyperlipemia, which can intensify side effects of asparaginase. When triglyceride elevation is greater than 1000 mg/dl, the risk of pancreatitis is significantly increased. We report two patients who were hospitalized in Department of Pediatric Hematology, Oncology and Transplantology, Medical University of Lublin in Poland and developed severe hypertriglyceridemia after receiving asparaginase and steroid therapy for acute lymphoblastic leukemia. These patients were treated using plasmapheresis. This procedure was performed with a venous catheter in the femoral vein and 5% albumin or fresh frozen plasma as the replacement fluid. We analysed the laboratory and clinical data of these children. Plasmapheresis was well tolerated in both cases and a decrease of hypertriglyceridemia was quickly observed. However, the girl developed pancreatitis. In our opinion, plasmapheresis appears to be safe and effective in reducing hypertriglyceridemia. We could recommend that this procedure should be performed early, as soon as the triglyceride level is above 1000 mg/dl, in order to prevent severe complications. Patients should continue chemotherapy without ASP. It is important to regularly monitor of the lipid profile, pancreatic enzymes and coagulation during ASP and steroids therapy.
