Hypertriglyceridemia is an increasingly recognized cause of acute pancreatitis in children, requiring acute interventions like dietary restriction and insulin, though pediatric-specific guidelines remain poorly established.
This review highlights that while hypertriglyceridemia-induced acute pancreatitis is increasingly recognized in children, evidence-based management guidelines are lacking and largely extrapolated from adult data.
Severe hypertriglyceridemia (HTG) is a known metabolic cause of acute pancreatitis (AP) in pediatric patients. The incidence of hypertriglyceridemia-induced acute pancreatitis (HTG-AP) is less well established in pediatric compared to adult patients. Studies in adults suggest that higher risk of AP occurs when triglyceride levels (TG) are >1,000 mg/dL. Most common etiologies for severe HTG in pediatric patients are either from primary hypertriglyceridemia, underlying genetic disorders of lipid and TG metabolism, or secondary hypertriglyceridemia, separate disease or exposure which affects TG metabolism. Most common theories for the pathophysiology of HTG-AP include hydrolysis of TG by pancreatic lipase to free fatty acids leading to endothelial and acinar cell damage and ischemia, as well as hyperviscosity related to increased chylomicrons. Though there are varying reports of HTG-AP severity compared to other causes of AP, a steadily growing body of evidence suggests that HTG-AP can be associated with more severe course and complications. Therapeutic interventions for HTG-AP typically involve inpatient management with dietary restriction, intravenous fluids, and insulin; select patients may require plasmapheresis. Long term interventions generally include dietary modification, weight management, control of secondary causes, and/or antihyperlipidemic medications. Though some therapeutic approaches and algorithms exist for adult patients, evidence-based management guidelines have not been well established for pediatric patients.
Grisham et al. (Thu,) conducted a review in Hypertriglyceridemia-induced acute pancreatitis. Management of hypertriglyceridemia-induced acute pancreatitis was evaluated. Hypertriglyceridemia is an increasingly recognized cause of acute pancreatitis in children, requiring acute interventions like dietary restriction and insulin, though pediatric-specific guidelines remain poorly established.
