Hypertriglyceridemia-induced pancreatitis in pregnancy: case review on the role of therapeutic plasma exchange

Abstract

Summary

Gestational hypertriglyceridemia-induced pancreatitis is associated with significant maternal and fetal morbidity and mortality. We report a case of gestational hypertriglyceridemia-induced pancreatitis in a primigravida at 31-weeks gestation, complicated by impending preterm labor and metabolic acidosis requiring hemodialysis. This was successfully managed with therapeutic plasma exchange (TPE), followed by i.v. insulin, low-fat diet, and omega-3. Triglyceride levels stabilized after TPE and the patient underwent an uncomplicated term delivery. In pregnancy, elevated estrogen and insulin resistance exacerbate hypertriglyceridemia. Management is challenging as risks and benefits of treatment options need to be weighed against fetal wellbeing. We discuss management options including a review of previous case reports detailing TPE use, dietary optimization, and delivery timing. This case emphasizes the importance of multidisciplinary care to optimize maternal and fetal outcomes.

Learning points

• Gestational hypertriglyceridemia-induced pancreatitis has high morbidity.

• A multidisciplinary team approach is a key as maternal and fetal needs must be addressed.

• Rapid lowering of triglycerides is crucial and can be achieved successfully and safely with plasma exchange.

• A low-fat diet while ensuring adequate nutrition in pregnancy is important.

• Timing of delivery requires consideration of fetal maturity and risk of recurrent pancreatitis.
