RESUMO

BACKGROUND Close observation, statins, fibrate treatment, and lifestyle changes can safely manage asymptomatic individuals with severe hypertriglyceridemia (HTG) and minimal risk of symptom development. However, the risk of medication-induced liver injury in patients taking statin-fibrate makes management more challenging, and may require hospital admission and close monitoring with follow-up. CASE REPORT We present a rare case of a 43-year-old man with asymptomatic severe HTG exceeding 11.370 mg/dL with mixed hyperlipidemia, managed initially with high-intensity statins and fibrate. However, due to the concurrent use of statin and fibrates, the patient subsequently developed an acute liver injury. Hence, the oral medications had to be stopped, and the patient was admitted to the hospital for an insulin drip. Even during the hospital course, the patient's triglyceride (TG) levels showed resistance to the recommended dose of insulin and he required a higher insulin dose. He was discharged on fenofibrate and subcutaneous insulin to keep the TG level under 500. Fibrate was stopped, and high-intensity statin was used as primary prevention with lifestyle modifications. CONCLUSIONS This instance highlights the necessity of increased cognizance and cooperative endeavors in handling severe asymptomatic HTG. Our results highlight the significance of further research into the management of severe asymptomatic HTG in cases of injury to the liver. This work adds essential knowledge to the ongoing discussion about managing a rare case complicated by acute liver injury.

RESUMO

BACKGROUND: Elevated lipoprotein(a) (Lp[a]) concentrations are associated with increased cardiovascular event risk even in the presence of well-controlled low-density lipoprotein cholesterol levels, but few treatments are documented to reduce this residual risk. OBJECTIVES: The aim of this post hoc analysis of REDUCE-IT (Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial) was to explore the cardiovascular benefit of icosapent ethyl (IPE) across a range of Lp(a) levels. METHODS: A total of 8,179 participants receiving statin therapy with established cardiovascular disease or age ≥50 years with diabetes and ≥1 additional risk factor, fasting triglyceride 1.69 to 5.63 mmol/L, and low-density lipoprotein cholesterol 1.06 to 2.59 mmol/L were randomized to receive 2 g twice daily of IPE or matching placebo. Relationships between continuous baseline Lp(a) mass concentration and risk for first and total (first and subsequent) major adverse cardiovascular events (MACE) were analyzed, along with the effects of IPE on first MACE among those with Lp(a) concentrations ≥50 or <50 mg/dL. RESULTS: Among 7,026 participants (86% of those randomized) with baseline Lp(a) assessments, the median concentration was 11.6 mg/dL (Q1-Q3: 5.0-37.4 mg/dL). Lp(a) had significant relationships with first and total MACE (P < 0.0001), while event reductions with IPE did not vary across the range of Lp(a) (interaction P > 0.10). IPE significantly reduced first MACE in subgroups with concentrations ≥50 and <50 mg/dL. CONCLUSIONS: Baseline Lp(a) concentration was prognostic for MACE among participants with elevated triglyceride levels receiving statin therapy. Importantly, IPE consistently reduced MACE across a range of Lp(a) levels, including among those with clinically relevant elevations.

RESUMO

OBJECTIVES: Identifying patients with severe hypertriglyceridemia (HTG) who are prone to developing hypertriglyceridemic pancreatitis (HTGP) is essential for facilitating preventative interventions. This research aims to explore which part of the HTG patients is easy to develop into HTGP. MATERIALS AND METHODS: An observational cohort study was conducted in patients with serum triglycerides (TGs) ≥ 5.65 mmol/L. Propensity score matching (PSM) and logistic regression were used to adjust for potential confounding factors. Receiver operating characteristic (ROC) curves were applied to evaluate the predictive potential for HTGP. RESULTS: A total of 283 patients were included finally with a PSM cohort consisting of 55 HTGP matched with 77 non-HTGP. In multivariate logistic regression analysis, fatty liver (FL) (odds ratio, 2.535; P = 0.019) showed statistically significant association with HTGP, whereas statin use was correlated with a lower rate of HTGP (odds ratio, 0.203; P = 0.009). Finally, the ROC analysis showed that the TGs threshold thought to be causal of HTGP in patients with FL was significantly lower (9.31 vs 14.67 mmol/L) than that in patients without FL. CONCLUSIONS: Although with lower TGs levels, patients with FL are much more prone to generate HTGP, and our findings suggest a potential role of statin as protective agents against HTGP.

RESUMO

Introduction: Hypertriglyceridemia is the most prevalent dyslipidemia in patients with chronic kidney disease (CKD). However, research about fibrate treatment in CKD patients is limited, and assessing its benefits becomes challenging due to the frequent concurrent use of statins. Thus, this study is aimed to investigate the role of fibrate in CKD stage 3 patients with hypertriglyceridemia who did not receive other lipid-lowering agents. Methods: This study enrolled patients newly diagnosed CKD3 with LDL-C<100mg/dL and had never received statin or other lipid-lowering agents from Chang Gung Research Database. The participants were categorized into 2 groups based on the use of fibrate: fibrate group and non-fibrate group (triglyceride >200mg/dL but not receiving fibrate treatment). The inverse probability of treatment weighting was performed to balance baseline characteristics. Results: Compared with the non-fibrate group (n=2020), the fibrate group (n=705) exhibited significantly lower risks of major adverse cardiac and cerebrovascular events (MACCEs) (10.4% vs. 12.8%, hazard ratios [HRs]: 0.69, 95% confidence interval [CI]: 0.50 to 0.95), AMI (2.3% vs. 3.9%, HR: 0.52, 95% CI: 0.37 to 0.73), and ischemic stroke (6.3% vs. 8.0%, HR: 0.67, 95% CI: 0.52 to 0.85). The risk of all-cause mortality (5.1% vs. 4.5%, HR: 1.09, 95% CI: 0.67 to 1.79) and death from CV (2.8% vs. 2.3%, HR: 1.07, 95% CI: 0.29 to 2.33) did not significantly differ between the 2 groups. Conclusion: This study suggests that, in moderate CKD patients with hypertriglyceridemia but LDL-C < 100mg/dL who did not take other lipid-lowering agents, fibrates may be beneficial in reducing cardiovascular events.

RESUMO

Hypertriglyceridemia and decreased high-density lipoprotein cholesterol (HDL-C) persist despite statin therapy, contributing to residual atherosclerotic cardiovascular disease (ASCVD) risk. Asian subjects are metabolically more susceptible to hypertriglyceridemia than other ethnicities. Fenofibrate regulates hypertriglyceridemia, raises HDL-C levels, and is a recommended treatment for dyslipidemia. However, data on fenofibrate use across different Asian regions are limited. This narrative review summarizes the efficacy and safety data of fenofibrate in Asian subjects with dyslipidemia and related comorbidities (diabetes, metabolic syndrome, diabetic retinopathy, and diabetic nephropathy). Long-term fenofibrate use resulted in fewer cardiovascular (CV) events and reduced the composite of heart failure hospitalizations or CV mortality in type 2 diabetes mellitus. Fenofibrate plays a significant role in improving irisin resistance and microalbuminuria, inhibiting inflammatory responses, and reducing retinopathy incidence. Fenofibrate plus statin combination significantly reduced composite CV events risk in patients with metabolic syndrome and demonstrated decreased triglyceride and increased HDL-C levels with an acceptable safety profile in those with high CV or ASCVD risk. Nevertheless, care is necessary with fenofibrate use due to possible hepatic and renal toxicities in vulnerable individuals. Long-term trials and real-world studies are needed to confirm the clinical benefits of fenofibrate in the heterogeneous Asian population with dyslipidemia.

RESUMO

Hypertriglyceridemia is a rare but significant cause of pancreatitis in children. Hypertriglyceridemic pancreatitis is often correlated with more severity and complications like pancreatic necrosis. Therefore, proper management and prevention of further episodes is essential. The authors report a case of a child with hypertriglyceridemic pancreatitis who was managed with intravenous insulin. According to various case reports and case series, intravenous insulin has been found to be effective in hypertriglyceridemic pancreatitis in adults. Few case reports in children also have mentioned use of intravenous insulin in diabetic ketoacidosis with hypertriglyceridemia. The authors found intravenous insulin to be highly effective in management of pancreatitis due to severe hypertriglyceridemia in the present child.

RESUMO

BACKGROUND: A French intersociety consensus on behalf the Société Française de Médecine Vasculaire and the Société de Chirurgie Vasculaire et Endovasculaire was proposed in 2021 for the management of patients with lower extremity peripheral artery disease (LEAD). Recent studies have been published and an update of this consensus about the management of low-density lipoprotein cholesterol (LDLc) and hypertriglyceridemia was required. METHODS: A steering committee of 12 vascular physicians and surgeons defined questions of interest about LDLc and hypertriglyceridemia management. A French expert panel voted the proposals. Consensus was considered to have been achieved if more than 80% of the responses corresponded to either "Agreement" or "Disagreement". RESULTS: Among the 56 experts who were asked to participate, 46 (82%) accepted. After the first round of the Delphi procedure, the 4 proposals reached consensus. The following suggestions and recommendations were approved: 1. For LEAD patients treated by the highest tolerated statin dose ± ezetimibe and who have an LDLc ≥0.70 g/L, we recommend adding a proprotein convertase subtilisin/kexin type 9 inhibitor. 2. For LEAD patients treated by statin and who have elevated triglyceride level between ≥150 mg/dL and ≤500 mg/dL, we suggest adding Icosapent Ethyl. 3. Before adding Icosapent Ethyl in LEAD patients treated with statin, we suggest looking for symptoms that may suggest atrial fibrillation. 4. For LEAD patients treated by Icosapent Ethyl and who have symptoms that suggest atrial fibrillation, we recommend performing an electrocardiogram. CONCLUSIONS: This update will help clinicians to improve LEAD patient management.

RESUMO

HDL particles vary in lipidome and proteome, which dictate their individual physicochemical properties, metabolism, and biological activities. HDL dysmetabolism in nondiabetic hypertriglyceridemia (HTG) involves subnormal HDL-cholesterol and apoAI levels. Metabolic anomalies may impact the qualitative features of both the HDL lipidome and proteome. Whether particle content of bioactive lipids and proteins may differentiate HDL subclasses (HDL2b, 2a, 3a, 3b, and 3c) in HTG is unknown. Moreover, little is known of the effect of statin treatment on the proteolipidome of hypertriglyceridemic HDL and its subclasses. Nondiabetic, obese, HTG males (n = 12) received pitavastatin calcium (4 mg/day) for 180 days in a single-phase, unblinded study. ApoB-containing lipoproteins were normalized poststatin. Individual proteolipidomes of density-defined HDL subclasses were characterized prestatin and poststatin. At baseline, dense HDL3c was distinguished by marked protein diversity and peak abundance of surface lysophospholipids, amphipathic diacylglycerol and dihydroceramide, and core cholesteryl ester and triacylglycerol, (normalized to mol phosphatidylcholine), whereas light HDL2b showed peak abundance of free cholesterol, sphingomyelin, glycosphingolipids (monohexosylceramide, dihexosylceramide, trihexosylceramide, and anionic GM3), thereby arguing for differential lipid transport and metabolism between subclasses. Poststatin, bioactive lysophospholipid (lysophosphatidylcholine, lysoalkylphosphatidylcholine, lysophosphatidylethanolamine, and lysophosphatidylinositol) cargo was preferentially depleted in HDL3c. By contrast, baseline lipidomic profiles of ceramide, dihydroceramide and related glycosphingolipids, and GM3/phosphatidylcholine were maintained across particle subclasses. All subclasses were depleted in triacylglycerol and diacylglycerol/phosphatidylcholine. The abundance of apolipoproteins CI, CII, CIV, and M diminished in the HDL proteome. Statin treatment principally impacts metabolic remodeling of the abnormal lipidome of HDL particle subclasses in nondiabetic HTG, with lesser effects on the proteome.

RESUMO

Hypertriglyceridemia is a type of dyslipidemia characterized by high triglyceride levels in the blood and increases the risk of cardiovascular disease. Conventional management includes antilipidemic medications such as statins, lowering LDL and triglyceride levels as well as raising HDL levels. However, the treatment may be stratified using omega-3 fatty acid supplements such as eicosatetraenoic acid (EPA) and docosahexaenoic acid (DHA), aka fish oil derivatives. Studies have shown that fish oil supplements reduce the risk of cardiovascular diseases; however, the underlying mechanism and the extent of reduction in CVD need more clarification. Our paper aims to review the clinical trials and observational studies in the current literature, investigating the use of fish oil and its benefits on the cardiovascular system as well as the proposed underlying mechanism.

RESUMO

PURPOSE OF REVIEW: The role of the inhibition of ANGPTL3 in severe or refractory hypercholesterolemia is well documented, less in severe hyperTG. This review focuses on the preclinical and clinical development of ApoC-III inhibitors and ANGPTL3, 4, and 3/8 complex inhibitors for the treatment of severe or refractory forms of hypertriglyceridemia to prevent cardiovascular disease or other morbidities. RECENT FINDINGS: APOC3 and ANGPTL3 became targets for drug development following the identification of naturally occurring loss of function variants in families with a favorable lipid profile and low cardiovascular risk. The inhibition of ANGPTL3 covers a broad spectrum of lipid disorders from severe hypercholesterolemia to severe hypertriglyceridemia, while the inhibition of ApoC-III can treat hypertriglyceridemia regardless of the severity. Preclinical and clinical data suggest that ApoC-III inhibitors, ANGPTL3 inhibitors, and inhibitors of the ANGPTL3/8 complex that is formed postprandially are highly effective for the treatment of severe or refractory hypertriglyceridemia. Inhibition of ANGPTL3 or the ANGPTL3/8 complex upregulates LPL and facilitates the hydrolysis and clearance of triglyceride-rich lipoproteins (TRL) (LPL-dependent mechanisms), whereas ApoC-III inhibitors contribute to the management and clearance of TRL through both LPL-dependent and LPL-independent mechanisms making it possible to successfully lower TG in subjects completely lacking LPL (familial chylomicronemia syndrome). Most of these agents are biologicals including monoclonal antibodies (mAb), antisense nucleotides (ASO), small interfering RNA (siRNA), or CRISPR-cas gene editing strategies.

RESUMO

Chemotherapy-induced hypertriglyceridaemia (HTG) is a potential serious adverse event. Severe HTG with triglycerides (TG) >11.3 mmol/L (1000 mg/dL) can cause acute pancreatitis in addition to cardiovascular diseases such as coronary artery disease. While the association of capecitabine (5-fluorouracil (5-FU) prodrug) with clinically relevant HTG is a well-known adverse reaction, 5-FU is not typically associated with HTG. We here report the case of a patient who developed 5-FU-associated grade 4 HTG with TG level raising up to 37.1 mmol/L (3286 mg/dL) occurring after the ninth cycle of adjuvant FOLFOX (Fluorouracil and Oxaliplatin) chemotherapy. Fenofibrate treatment and diet were started. Chemotherapy was postponed and then resumed for two additional cycles. However, severe HTG recurred shortly after. Chemotherapy was therefore permanently stopped. Approximately 8 weeks after chemotherapy discontinuation, TG fell back to range at 2.1 mmol/L (189 mg/dL) allowing interruption of fenofibrate without HTG recurrence at 3 months.

RESUMO

Antipsychotic medications increase the risk of abnormal glucose metabolism. However, in clinical practice, it is difficult to predict this risk because it is affected by medication-related and background factors. This study aimed to identify the risk factors for abnormal glucose metabolism during antipsychotic treatment. We conducted a multicenter, prospective, cohort study in patients with schizophrenia, schizoaffective disorder, or bipolar disorder. Of these patients, those with prediabetes or possible diabetes were excluded. Finally, 706 patients were included in the analysis. The hazard ratio (HR) for each factor was calculated for events of progression to hyperglycemia using time-dependent Cox regression analysis stratified according to facility type and adjusted for available background and drug-related factors. Treatments with olanzapine (HR = 2.06, 95% confidence interval [CI] = 1.05-4.05), clozapine (HR = 4.25, 95% CI = 1.56-11.60), and chlorpromazine (HR = 4.48, 95% CI = 1.21-16.57), overweight and obesity (HR = 1.57, 95% CI = 1.02-2.41), and hypertriglyceridemia (HR = 1.72, 95% CI = 1.02-2.88) were associated with a significantly higher occurrence of hyperglycemic progression. The number and daily dose of antipsychotics were not associated with their occurrence. Our study demonstrated that more careful monitoring is necessary during olanzapine, clozapine, and chlorpromazine treatment because of the higher occurrence of abnormalities in glucose metabolism. Furthermore, patients with obesity or hypertriglyceridemia warrant monitoring for the occurrence of abnormal glucose metabolism, regardless of the type of antipsychotic medication.

RESUMO

We present the inhibitory properties of the Solanum nigrescens anthocyanin fraction (SNAF) and its major constituents on alpha-glucosidase (AG), pancreatic lipase (PL), HMG-CoA reductase, and ornithine decarboxylase (ODC). The effect of SNAF was simultaneously evaluated in ICR male mice exposed to triglyceride charge test (TCT). HPLC-MS profiling revealed the presence cyanidin-3-O-rutinoside-5-glucoside (CRG), delphinidin-3-(p-coumaroyl)-rutinoside-5-glucoside (DCRG), and petunidin-3-(cis-p-coumaroyl)-rutinoside-5-glucoside (PCRG) as major constituents of the fraction. SNAF, CRG, and specially PCRG, induced strong non-competitive inhibition on PL (IC50 , 33-86 µg mL-1 ). The results of TCT confirmed their capacity to ameliorate (p <0.001) hypertriglyceridemia during postprandial and interdigestive stages. SNAF, CRG, DCRG, and PCRG caused negligible growth inhibition (MIC>600 µg mL-1 ) on beneficial bacteria whereas SNAF and DCRG exerted inhibitory activity on Helicobacter pylori ATCC 53504 (MIC,187-64 µg mL-1 ). Additional exploration revealed that SNAF and DCRG produced non-competitive activity on H. pylori urease, which facilitates bacterial growth under acidic conditions.

RESUMO

Severe hypertriglyceridemia (sHTG), defined as a triglyceride (TG) concentration ≥ 500 mg/dL (≥ 5.7 mmol/L) is an important risk factor for acute pancreatitis. Although lifestyle, some medications, and certain conditions such as diabetes may lead to HTG, sHTG results from a combination of major and minor genetic defects in proteins that regulate TG lipolysis. Familial chylomicronemia syndrome (FCS) is a rare disorder caused by complete loss of function in lipoprotein lipase (LPL) or LPL activating proteins due to two homozygous recessive traits or compound heterozygous traits. Multifactorial chylomicronemia syndrome (MCS) and sHTG are due to the accumulation of rare heterozygous variants and polygenic defects that predispose individuals to sHTG phenotypes. Until recently, treatment of sHTG focused on lifestyle interventions, control of secondary factors, and nonselective pharmacotherapies that had modest TG-lowering efficacy and no corresponding reductions in atherosclerotic cardiovascular disease events. Genetic discoveries have allowed for the development of novel pathway-specific therapeutics targeting LPL modulating proteins. New targets directed towards inhibition of apolipoprotein C-III (apoC-III), angiopoietin-like protein 3 (ANGPTL3), angiopoietin-like protein 4 (ANGPTL4), and fibroblast growth factor-21 (FGF21) offer far more efficacy in treating the various phenotypes of sHTG and opportunities to reduce the risk of acute pancreatitis and atherosclerotic cardiovascular disease events.

RESUMO

BACKGROUND AND AIM: Elevated triglyceride (TG) levels seem to identify subjects at increased cardiovascular risk, independent of LDL-C levels. We sought to evaluate the predictive role of hypertriglyceridemia, defined as TG levels ≥150 mg/dl, in very high risk (VHR) patients with chronic coronary syndromes (CCS) treated with statins. METHODS AND RESULTS: Using the data from the STable Coronary Artery Diseases RegisTry (START) study, an Italian nationwide registry, we assessed the association between the TG levels and baseline clinical characteristics, pharmacological treatment and major adverse cardio-cerebrovascular events (MACCE) at 1 year in a large cohort of statin-treated patients at VHR. Of the 4751 consecutive patients with CCS enrolled in the registry and classified as VHR, 2652 (55.8%) had TG values available (mean 120.6 ± 54.9) and were treated with at least a statin at baseline: 2019 (76.1%) with TG < 150 and 633 (23.9%) with TG ≥ 150 mg/dl. At 1 year from enrolment, MACCE occurred in 168 (6.3%) patients, without differences between the two groups of TG (5.9 vs 7.6%; p = 0.14). At multivariable analysis, hypertriglyceridemia did not result as independent predictor of the MACCE (hazard ratio: 1.16; 95% confidence intervals: 0.82-1.64; p = 0.42). CONCLUSIONS: In the present large, nationwide cohort of consecutive CCS patients at VHR with statin-controlled LDL-C levels, hypertriglyceridemia was present in around 24% of cases and did not result as predictor of MACCE at 1 year. Further studies with a longer follow-up and larger sample size are needed to better define the prognostic role of TG levels when intensive LDL lowering therapies are used.

RESUMO

OBJECTIVE: To characterize the time course of triglyceride (Tg) lowering in hypertriglyceridemic (HTg) pancreatitis according to the initial Tg values, causes, and interventions. METHODS: Patients hospitalized from October 2013 through December of 2018 with a diagnosis of pancreatitis associated with HTg (Tg level, ≥500 mg/dL), in the absence of other causes, were identified by medical record review. Tg lowering was retrospectively assessed for differences in relation to the initial Tg values, use of intravenous insulin, ethanol-associated versus nonethanol-associated causes, and time to Tg values of <500 versus <1000 mg/dL. RESULTS: Sixty-six cases were identified, and 45 had multiple measurements for time-course evaluation. Those with initial Tg values of <4000 mg/dL achieved Tg levels of <1000 mg/dL in <3 days, whereas 18.8% with higher values took 5-9 days. Insulin therapy was associated with a longer duration of HTg, whereas ethanol was associated with a shorter duration. Tg clearance in ethanol-associated HTg appeared independent of insulin treatment. Time to Tg levels of <500 mg/dL versus <1000 mg/dL was significantly longer when the initial Tg levels were >2000 mg/dL. CONCLUSION: A threshold of 4000 mg/dL for the initial Tg levels in HTg pancreatitis appears to separate patients who are likely to achieve Tg levels of <1000 mg/dL in <3 versus >3 days, independent of cause or treatment. Insulin therapy is appropriate for patients with hyperglycemia but appears unnecessary for those with isolated ethanol-associated HTg. A threshold Tg level of <1000 mg/dL appears more practical than that of <500 mg/dL for resuming nutritional intake.

RESUMO

BACKGROUND: Hypertriglyceridemia (HTG) increases the risk of cardiovascular disease and pancreatitis, and its prevalence varies across populations. OBJECTIVE: To determine the prevalence of moderate-to-severe hypertriglyceridemia (msHTG, 500-879 mg/dl) and severe hypertriglyceridemia (sHTG, ≥ 880 mg/dl) in a primary care population in Catalonia, Spain, and to categorize them according to presence/absence of factors potentially causing HTG. METHODS: Retrospective analysis of clinical and laboratory data in SIDIAP (Information System for the Development of Primary Care Research) from 2010, 2013, 2016, and 2019. We considered medications with hypolipidemic effects and those potentially increasing TG levels. We developed logistic regression models adjusted by age and sex to calculate the probability of having ms/sHTG according to covariates of interest. RESULTS: In the study years, 36.2‒42.0% of the >3.5 million active primary care users had ≥1 TG determination. Prevalence for msHTG was 0.7% and for sHTG 0.2% among those with recorded TG. In 2019, 54.7% were female; median (IQR) age was 62.5 (49.4‒73.7) years. Prevalence was higher in 36‒50-year-old persons (1.3% msHTG, 0.4% sHTG) and men (1.1% msHTG, 0.3% sHTG). Most cases were associated with secondary and <20% with non-secondary causes, the latter being most prevalent in young patients. The secondary causes more strongly associated with msHTG/sHTG were obesity, uncontrolled diabetes mellitus (DM) and gamma-glutamyl transferase >100 U/L. CONCLUSION: The prevalence of msHTG was 0.7% and that of sHTG was 0.2% between 2010 and 2019 among individuals with recorded TG. msHTG/sHTG most often affected men around their fifties and people with obesity and uncontrolled DM. Most msHTG and sHTG cases were associated with the presence of secondary causes.

RESUMO

PURPOSE OF REVIEW: To provide an insight into the new pharmacological options for the treatment of severe hypertriglyceridemia (sHTG). RECENT FINDINGS: sHTG is difficult to treat. The majority of the traditional pharmacological agents available have limited success in both robustly decreasing triglyceride levels and/or in reducing the incidence of acute pancreatitis (AP), the most severe complication of sHTG. Therapeutic options with novel mechanisms of action have been developed, such as antisense oligonucleotides (ASO) and small interfering RNA (siRNA) targeting APOC3 and ANGPTL3. The review discusses also 2 abandoned drugs for sHTG treatment, evinacumab and vupanorsen. The ASO targeting APOC3, volanesorsen, is approved for use in patients with familial chylomicronemia syndrome (FCS) in Europe. Olezarsen, an N-acetylgalactosamine (GalNAc)-conjugated ASO with the same target, seems to have a better safety and efficacy profile. siRNA targeting APOC3 and ANGPTL3, namely ARO-APOC3 and ARO-ANG3, are also promising for the treatment of sHTG. However, the ultimate clinical goal of any sHTG treatment, the decrease in the risk of AP, has not been definitively achieved till now by any pharmacotherapy, either approved or in development.
