Severe Hypertriglyceridemia: An indication for apheresis?

ObjectiveSevere hypertriglyceridemia is associated with a number of severe complications such as acute pancreatitis. Rapid lowering of excessively elevated triglyceride (TG) levels is therefore a primary medical goal in these patients. According to previous reports, immediate apheretic treatment might be an interesting option in order to rapidly lower excessively elevated TG levels.MethodsA review of the current available literature was therefore conducted in order to provide an overview of the present data on apheretic treatment for patients with severe hypertriglyceridemia.ResultsA single session of plasmapheresis proofs capable of lowering TG levels by up to 70%, producing clear clinical and laboratory improval. The best clinical benefit concerning reduction in morbitity and mortality can be achieved when apheresis is used as early as possible. Even repetitive use of apheresis is reported. There is controversy on technical details, such as different apheresis techniques (plasma exchange versus double-membrane filtration), slightly favoring plasma exchange.ConclusionsIn patients with severe hypertriglyceridemia plasmapheresis seems to be a safe and useful tool in rapidly lowering excessively elevated TG levels. Apheresis can be used to rapidly decrease triglyceride levels, and thus remove the causative agent for continuing damage. The indications are medical emergencies such as hypertriglyceridemic pancreatitis with excessively elevated TG levels (TG > 1000 mg/dl). If indicated, it should be used as early as possible.
