Abstract

Objectives

Severe and very severe hypertriglyceridemia although rare within the pediatric population occur more often among oncology patients, secondary to chemotherapeutic agents. Currently there exists minimal literature to guide management of severe hypertriglyceridemia among pediatric patients. Very-low-fat dietary restriction should be considered over nil per os (NPO) for initial management of severe hypertriglyceridemia in stable pediatric patients. Pediatricians caring for oncology patients must consider chylomicronemia as a potential etiology for presenting symptoms. Pediatric severe hypertriglyceridemia management guidelines are needed as pediatricians must currently rely on anecdotal experiences for management decisions.

Case presentation

Three children receiving treatment for acute lymphoblastic leukemia required hospitalization for very severe hypertriglyceridemia. Management varied among the cases but included: NPO or very-low-fat diet, insulin, intravenous fluids, fibrates, and omega-3 fatty acids.

Conclusions

These cases suggest that pediatric severe hypertriglyceridemia management, in the absence of pancreatitis should allow a very-low-fat diet initially rather than NPO followed by pharmacologic therapies.
