SEVERE HYPERTRIGLYCERIDEMIA IN PREGNANCY: A CASE REPORT AND REVIEW OF THE LITERATURE

Lipid Disorders and Pregnancy

Practicing endocrinologists are likely to confront 2 major issues that occur with dyslipidemias during pregnancy. The most dramatic is the development of severe hypertriglyceridemia leading to acute pancreatitis. The second is the approach to treatment of familial hypercholesterolemia, a common genetic disorder. This article reviews the normal physiology and the pathophysiology of lipoproteins that occurs with pregnancy and then discusses the approaches to prevention and/or treatment of dyslipidemia in pregnancy with a focus on lifestyle and acceptable drug therapies.

Approach to the Management of Hypertriglyceridemia Complicated With Acute Pancreatitis in Pregnancy: A Case Report

This is a case of a 32-year-old woman, Gravida 3 para 2, previous two cesarean sections, who presented to our emergency department at 24+3 weeks of gestation complaining of severe epigastric pain radiating to the back. She was diagnosed with severe hypertriglyceridemia complicated with acute pancreatitis and was managed by a multi-disciplinary team, which included obstetrics, gastroenterology, endocrinology, hematology, nutrition, and ICU team. Initially, conservative treatment was employed for her management. She was placed on nil per oral status and initiated on a normal saline infusion at a rate of 150 ml/hour, along with insulin infusion at 0.1 unit/kg/hour and dextrose (D5) at 80 ml/hour. Additionally, she received omeprazole, meropenem, clexane (40 mg once daily subcutaneous injection), iron, vitamin supplements, and analgesics as required. Subsequently, due to the failure of the initial conservative medical management, the patient was admitted to the ICU. Plasmapheresis was performed after the insertion of a vascath, using 3000 ml of albumin 5% as replacement fluid and oral calcium. Following this, she was prescribed Omacor (Omega 3) at a dosage of 2 grams orally twice daily, along with a low carbohydrate and fat diet, to manage her triglyceride levels. After the removal of the central line, her triglycerides increased to 14.3 mmol/L, leading to the initiation of fenofibrate at a daily dose of one tablet. With persistent elevation to 16.4 mmol/L, Lipitor at 40 mg once daily was introduced. Following this intervention, her triglyceride levels stabilized, and her overall condition improved. She was discharged at 25+1 weeks with a prescribed regimen, and scheduled follow-ups were arranged in the endocrine and obstetrics clinics. At 36 weeks of gestation, she presented to the emergency room with abdominal, back, and leg pain. Fetal distress, indicated by fetal tachycardia (170-180 bpm) on cardiotocography, prompted an urgent category 1 cesarean section, which proceeded without complications.

EASL Clinical Practice Guidelines on the management of liver diseases in pregnancy

Liver diseases in pregnancy comprise both gestational liver disorders and acute and chronic hepatic disorders occurring coincidentally in pregnancy. Whether related to pregnancy or pre-existing, liver diseases in pregnancy are associated with a significant risk of maternal and fetal morbidity and mortality. Thus, the European Association for the Study of Liver Disease invited a panel of experts to develop clinical practice guidelines aimed at providing recommendations, based on the best available evidence, for the management of liver disease in pregnancy for hepatologists, gastroenterologists, obstetric physicians, general physicians, obstetricians, specialists in training and other healthcare professionals who provide care for this patient population.

A case of eruptive xanthomas associated with pregnancy unmasking a G188E heterozygous mutation of the lipoprotein lipase gene: A case report

A case of eruptive xanthomas with exceptionally high levels of blood triglycerides without any complication during pregnancy is reported. Eruptive xanthomas may develop in the setting of severe hypertriglyceridemia. Clinically, patients present with small and smooth papules with a characteristic yellow hue. The condition can also be associated with morbid systemic complications. Estrogen replacement therapy is a known cause of secondary hypertriglyceridemia. Estrogen increase in pregnancy is associated with a physiologic elevation of blood triglycerides in order to provide sufficient nutrition for the fetus. However, in the setting of primary dyslipidemia, severe hypertriglyceridemia can occur. The case presented here was explained by a partial primary lipoprotein lipase deficiency with a heterozygous G188E mutation of the LPL gene. The delivery by induced labor and the introduction of fenofibrate led to a rapid decrease of triglycerides and a resolution of cutaneous lesions without any complication for the patient or her baby.

Hypertriglyceridaemia in pregnancy: an unexpected diagnosis and its management

A woman in her 30s with gestational diabetes presented at 36 weeks’ gestation with reduced fetal movements and diminishing insulin requirements. In view of her gestation, she was induced and incidentally found to have profound hyponatraemia. Further biochemical investigations confirmed severe hypertriglyceridaemia and hypercholesterolaemia. This raises the possibility of secondary causes such as familial dysbetalipoproteinemia and polygenetic hypertriglyceridaemia. She was successfully managed by aggressive dietary modification. This involved a supervised fast followed by a fat-free diet. A fenofibrate was proposed but declined due to our patient’s wish to breastfeed. Management required considerable input from the multidisciplinary team. Treatment options to consider are aggressive dietary restriction of fat or the addition of a cholesterol-lowering medication, such as a fibrate. In refractory cases, a supervised fast may be required or, in cases where complications have arisen, apheresis. The patient and her baby made a good recovery with no long-lasting health implications.

Case Report: Management of a Patient With Chylomicronemia Syndrome During Pregnancy With Medical Nutrition Therapy

Background: Hypertriglyceridemia (HTG) during pregnancy may be accompanied by acute pancreatitis, hyperviscosity syndrome, and preeclampsia. HTG during pregnancy should be managed by a multidisciplinary team; however, no clinical guidelines exist for severe gestational HTG.

Case Presentation: We herein present a case of a 36-year-old in the first pregnancy (G1P0Ab0), with a history of severe HTG-induced necrotizing pancreatitis 9 years earlier. There was no family history of HTG. During these years, she did not follow any appropriate diet or medical therapy for HTG. She became pregnant in May 2019, without preconception counseling. Eruptive and tuberoeruptive xanthomas appeared in the 27th week of pregnancy. Serum triglycerides (TGs) and fasting blood sugar (FBS) were 6,620 and 124 mg/dL, respectively, indicating HTG and gestational diabetes (GDM). After admission for the management of severe HTG, she was put on parenteral nutrition with dextrose water 5% and infusion insulin therapy without receiving any enteral carbohydrate for 2 days. Following that, a very low-fat diet and omega-3 fatty acids (1,200 mg/day) were started. After 4 weeks, TG levels reached 1,000 mg/dL, and her self-monitoring blood glucose levels showed appropriate blood glucose for pregnancy. She underwent a successful elective cesarean section in the 39th of pregnancy.

Conclusion: This case report demonstrates that HTG during pregnancy could be managed by medical nutrition therapy (MNT).

Treatment of Severe Hypertriglyceridemia During Pregnancy With High Doses of Omega-3 Fatty Acid and Plasmapheresis

Objective

Severe hypertriglyceridemia carries increased health risks, including the development of pancreatitis. The objective of this study was to report on management of 2 cases with severe gestational hypertriglyceridemia.

Cases

In case 1, a 33-year-old pregnant woman presented with serum triglyceride level of 14 000 mg/dL after discontinuing hypolipidemic medications. She was treated with Lovaza 12 g/day, and serum triglyceride remained near normal at level of less than 800 mg mg/dL until delivery. In case 2, a 28-year-old patient (29^th week gestation) presented with acute pancreatitis and triglycerides >4000 mg/dL. She was treated with Gemfibrozil, Lovaza, insulin infusion, subcutaneous heparin, and escalated to plasmapheresis. She successfully delivered a baby at the week of 36^th and her triglyceride level was 304 mg/dL after that.

Discussion

Case 1 was treated with high-dose Lovaza and case 2 was treated with plasmapheresis successfully. Triglyceride levels were reduced to less than 500 mg/dL until delivery of healthy babies in both cases.

Conclusion

Omega-3 fatty acids and plasmapheresis may be effective and safe to treat pregnant women with severe hypertriglyceridemia and pancreatitis.
