Key result
Exchange transfusion plus dietary lipid control rapidly lowers severe hypertriglyceridemia in infant LPL deficiency.
Why the study?
Lipoprotein lipase deficiency presentations are heterogeneous, there are no standardized acute treatment protocols, and the necessity of invasive management of severe hypertriglyceridemia is not established.

Manual whole-blood exchange transfusion followed by strict dietary restriction of long-chain fatty acids successfully managed severe hypertriglyceridemia and compensated shock in an infant with lipoprotein lipase deficiency.

May support acute triglyceride reduction via exchange transfusion in infantile LPL deficiency; hypothesis-generating case report that leaves open need for validation.
Lipoprotein lipase (LPL) deficiency is an autosomal recessive disorder causing hypertriglyceridemia. Presentations are heterogenous and there are no standardized acute treatment protocols. Long-term management consists of strict dietary control. We report a case of LPL deficiency in an infant presenting with gastrointestinal bleeding and compensated shock, with a more severe presentation than previously published cases. Preliminary diagnosis was based on lipemic blood appearance. Intensive care resuscitation was required. Triglyceride levels peaked above 200 times the upper limit of normal. Insulin infusion provided no benefit. A whole-blood exchange transfusion led to a sustained reduction in triglyceride levels. Diagnosis was confirmed by genetic testing. Despite the magnitude of hypertriglyceridemia, there were minimal end-organ sequelae. The necessity of invasive management of severe hypertriglyceridemia is not established. This case highlights the range of presentations in inherited metabolic disease, and the limited evidence for acute management strategies.

Rose et al. (2026) conducted a case report in Lipoprotein lipase deficiency (n=1). Whole-blood exchange transfusion and low-LCFA diet was evaluated on Reduction in triglyceride levels. Manual whole-blood exchange transfusion and strict dietary lipid control successfully reduced severe hypertriglyceridemia in an infant with lipoprotein lipase deficiency.
