Introduction: The prevalence of hypertriglyceridemia (HTG) is increasing. Elevated triglyceride (TG) levels are associated with an increased cardiovascular disease (CVD) risk. Moreover, severe HTG results in an elevated risk of pancreatitis, especially in severe HTG with an up to 350-fold increased risk. Both problems emphasize the clinical need for effective TG lowering.
Areas Covered: The purpose of this review is to discuss the currently available therapies and to elaborate the most promising novel therapeutics for TG lowering.
Expert Opinion: Conventional lipid lowering strategies do not efficiently lower plasma TG levels, leaving a residual CVD and pancreatitis risk. Both apolipoprotein C-III (apoC-III) and angiopoietin-like 3 (ANGPTL3) are important regulators in TG-rich lipoprotein (TRL) metabolism. Several novel agents targeting these linchpins have ended phase II/III trials. Volanesorsen targeting apoC-III has shown reductions in plasma TG levels up to 90%. Multiple ANGPLT3 inhibitors (evinacumab, IONIS-ANGPTL3-L, ARO-ANG3) effectuate TG reductions up to 70% with concomitant potent reduction in all other apoB containing lipoprotein fractions. We expect these therapeutics to become players in the treatment for (especially) severe HTG in the near future.

Article Synopsis
- The case involves a 21-month old girl with severe hypertriglyceridemia during cardiac surgery for a ventricular septal defect.
- A milky liquid was found in the bypass circuit, leading to tests that confirmed high triglycerides, necessitating careful management during surgery.
- The child recovered well, demonstrating the importance of quickly recognizing and addressing hypertriglyceridemia to prevent complications in pediatric heart operations.

Department of Gastroenterology and Hepatology, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, China.
Article Synopsis
- The study analyzed data from 2013 to 2021 on patients with acute pancreatitis (AP) in a Chinese city, revealing an increase in cases linked to hypertriglyceridemia and alcohol consumption while the prevalence of biliary-related AP remained stable.
- An increase in severe acute pancreatitis (SAP) cases was noted, with a rise in prevalence from 4.97% to 12.2% over the years, and male patients were found to have a higher occurrence of AP compared to females.
- Additionally, the median length of stay and hospitalization costs significantly decreased, while the overall in-hospital mortality rate remained constant throughout the study period.
Clinical and molecular characterization of familial chylomicronemia in Saudi patients: a retrospective study.

Department of Pediatrics, King Faisal Specialist Hospital & Research Centre, Riyadh, Saudi Arabia.
Article Synopsis
- - Familial chylomicronemia syndrome (FCS) is a rare but severe form of hypertriglyceridemia, with over 100 cases identified at a specific center aimed at supporting clinicians and enhancing knowledge in disease management.
- - A study of 29 pediatric patients revealed common symptoms such as milky blood samples, family history of hypertriglyceridemia, and acute pancreatitis, with gemfibrozil and fenofibrate proving effective in lowering triglyceride levels.
- - The findings suggest anti-triglyceride medications, particularly fibrates, are safe and effective in managing FCS in kids, with gemfibrozil showing superior results compared to fenofibrate and both drugs causing minimal side effects
Comparison of baseline clinical characteristics and patterns of visual field defects between high-tension and normal-tension glaucoma.
Br J Ophthalmol
November 2024
Department of Glaucoma, Sun Yat-Sen University Zhongshan Ophthalmic Center, Guangzhou, Guangdong, China
Article Synopsis
- The study aimed to compare the clinical characteristics and visual field defects between high-tension glaucoma (HTG) and normal-tension glaucoma (NTG) among patients in the LiGHT China trial.
- A total of 622 patients with open-angle glaucoma were analyzed, revealing that NTG patients tended to be older, predominantly female, and had higher rates of hypertension and ischaemic heart disease compared to HTG patients.
- While both groups showed similar severity in overall visual field defects, NTG exhibited notably greater asymmetry in visual field loss, which was correlated with fluctuations in daytime intraocular pressure.
