RESUMO

Hypertriglyceridemia (HTG) is a common cardiovascular risk factor characterized by elevated triglyceride (TG) levels. Researchers have assessed the genetic factors that influence HTG in studies focused predominantly on individuals of European ancestry. However, relatively little is known about the contribution of genetic variation of HTG in people of African ancestry (AA), potentially constraining research and treatment opportunities. Our objective was to characterize genetic profiles among individuals of AA with mild-to-moderate HTG and severe HTG versus those with normal TGs by leveraging whole-genome sequencing data and longitudinal electronic health records available in the All of Us program. We compared the enrichment of functional variants within five canonical TG metabolism genes, an AA-specific polygenic risk score for TGs, and frequencies of 145 known potentially causal TG variants between HTG patients and normal TG among a cohort of AA patients (N = 15,373). Those with mild-to-moderate HTG (N = 342) and severe HTG (N ≤ 20) were more likely to carry APOA5 p.S19W (odds ratio = 1.94, 95% confidence interval = [1.48-2.54], P = 1.63 × 10-6 and OR = 3.65, 95% confidence interval: [1.22-10.93], P = 0.02, respectively) than those with normal TG. They were also more likely to have an elevated (top 10%) polygenic risk score, elevated carriage of potentially causal variant alleles, and carry any genetic risk factor. Alternative definitions of HTG yielded comparable results. In conclusion, individuals of AA with HTG were enriched for genetic risk factors compared to individuals with normal TGs.

RESUMO

BACKGROUND AND AIMS: To study the role of gene mutations in the development of severe hypertriglyceridemia (HTG) in patients with hyperlipidemic acute pancreatitis (HLAP), especially different apolipoprotein A5 (APOA5) mutations. METHODS: Whole-exome sequencing was performed on 163 patients with HLAP and 30 patients with biliary acute pancreatitis (BAP). The pathogenicity of mutations was then assessed by combining clinical information, predictions of bioinformatics programs, information from multiple gene databases, and residue location and conservation. The pathogenic mutations of APOA5 were visualized using the software. RESULTS: 1. Compared with BAP patients, pathogenic mutations of APOA5 were frequent in HLAP patients; among them, the heterozygous mutation of p.G185C was the most common. 2. All six pathogenic mutations of APOA5 identified in this study (p.S35N, p.D167V, p.G185C, p.K188I, p.R223C, and p.H182fs) were positively correlated with severe HTG; they were all in the important domains of apolipoprotein A-V (apoA-V). Residue 223 is strictly conserved in multiple mammals and is located in the lipoprotein lipase (LPL)-binding domain (Pro215-Phe261). When Arg 223 is mutated to Cys 223, the positive charge of this residue is reduced, which is potentially destructive to the binding function of apoA-V to LPL. 3. Four new APOA5 mutations were identified, namely c.563A > T, c.667C > T, c.788G > A, and c.544_545 insGGTGC. CONCLUSIONS: The pathogenic mutations of APOA5 were specific to the patients with HLAP and severe HTG in China, and identifying such mutations had clinical significance in elucidating the etiology and subsequent treatment.

RESUMO

INTRODUCTION AND OBJECTIVES: TPE drastically reduces serum triglyceride (sTG), but its role in the treatment of hypertriglyceridemia-induced acute pancreatitis (HTG-AP) or at risk of developing it, is not well established. The objectives were to assess the effectiveness and safety of TPE in the treatment of severe HTG (sHTG), as well as to evaluate the severity of HTG-AP treated with TPE. MATERIALS AND METHODS: Observational-retrospective-single-center study, in which a descriptive analysis of sHTG treated with TPE was conducted, with the aim of treating HTG-AP or preventing its recurrence. TPE was performed if sTG≥ 1000 mg/dL after 24 hours of admission. RESULTS: 42 TPE were performed to treat 35 sHTG in 23 patients: 29 HTG-AP, and 6 sHTG with previous HTG-AP. Among the patients, 37% (13/55) were women, with 37 ± 14 years-old, 74.3% had normal BMI (25/35), 34% (12/35) were drinking > 40 g/alcohol/day and 54% (19/35) were diabetics. TPE significantly reduced the baseline sTG (4425 ± 2782 mg/dL vs. 709 ± 353 mg/dL, p < 0.001) in a single session, achieving a mean percentage reduction of 79 ± 13%; 20% (7/35) of sHTG cases required two TPE sessions to reduce sTG to < 1000 mg/dL. Adverse effects were reported in 4/42 TPE sessions (9,5%). sHTG-AP was observed in 3% of cases (1/29), and there were no deaths. sTG at 24 hours of admission showed no relation with the severity of APs. CONCLUSION: The treatment of sHTG with TPE, with the aim of treating HTG-AP or preventing its recurrence, reduces sTG quickly and safety.

RESUMO

Background and aim: Hypertriglyceridemia is one of the leading causes of acute pancreatitis and is associated with increased morbidity and mortality. Today the recommended treatment options are fasting, hydration, if necessary antibiotics and there is not a standard recommendation to decrease triglycerides rapidly. Double Filtration Plasmapheresis (DFPP) may be an option to decrease triglycerides rapidly but its effect on the disease course is unknown. Method: In the present study, we present results of four acute pancreatitis cases associated with hypertriglyceridemia treated with DFPP. All of the patients were diagnosed as acute pancreatitis at emergency room and no complications were observed in sessions. A 76.3% reduction in triglyceride levels was observed in one or two treatment sessions. Results and conclusion: DFPP is an effective and safe option to decrease triglyceride levels rapidly but further research is needed to show the effect on mortality and morbidity.

RESUMO

BACKGROUND: Neonatal severe hypertriglyceridemia is rarely reported in the literature and there is no consensus for hypertriglyceridemia management at this age group. METHODS: The index case is a 4-week-old male infant with severe hypertriglyceridemia accidentally discovered during a circumcision surgery. His clinical and genetic characteristics and his successful management strategy are described. Furthermore, a detailed ophthalmological examination of the proband was conducted at 3 and 6 months of age using Fourier-domain-optical coherence tomography. RESULTS: Triglycerides level at presentation was extremely high 33,727 mg/dL (380.8 mmol/L). Two sessions of exchange blood transfusion on two consecutive days successfully reduced triglycerides to 382 mg/dL (4.3 mmol/L) with no adverse effects. The infant was discharged 3 days later. At discharge, the mother was advised to continue breastfeeding together with a medium-chain triglycerides formula. Satisfactory growth parameters and lipid profile values were obtained for a follow-up duration of 5 months with no reported attacks of acute pancreatitis. Lipoprotein lipase deficiency was confirmed by the detection of the LPL homozygous pathogenic variant c.805G > A; p.(Glu269Lys). Early corneal and macular lesions were detected and persisted on follow-up despite relatively good lipemic control. CONCLUSION: This case highlights the importance of the early discovery of severe hypertriglyceridemia during the neonatal period, which is needed for prompt management and prevention of severe complications. Rationalized breastfeeding can be tolerated within the diet plan of the disease with satisfactory outcomes. To our knowledge, it is the first study reporting early corneal and macular affection by severe hypertriglyceridemia in a neonate. Prolonged follow-up is needed to determine the extent of ophthalmological lesions.

RESUMO

BACKGROUND: Currently available treatments have only been partly successful in patients with severe hypertriglyceridemia, including those with high serum triglycerides above 1,000 mg/dL (11.3 mmol/L), who often suffer from acute pancreatitis. Pemafibrate is a novel selective peroxisome proliferator-activated receptor α modulator (SPPARMα) which has been developed as an affordable oral tablet in Japan. We herein report the first three patients with severe hypertriglyceridemia who were successfully treated with pemafibrate. METHODS: Three patients with fasting serum triglyceride (TG) levels above 1,000 mg/dL (11.3 mmol/L) were treated with pemafibrate (0.2-0.4 mg/day, 0.1-0.2 mg BID). RESULTS: Serum TGs decreased from 2,000-3,000 mg/dL (22.6-33.9 mmol/L) to < 250 mg/dL (2.8 mmol/L) without adverse effects in all three patients. Serum TGs in Patient 1 and 2 decreased from 1,326 mg/dL (15.0 mmol/L) to 164 mg/dL (1.9 mmol/L) and from 2,040 mg/dL (23.1 mmol/L) to 234 mg/dL (2.6 mmol/L), respectively. Patient 3 with type 2 diabetes and 12.1% (109 mmol/mol) hemoglobin A1c had a TG level of 2,300 mg/dL (26.0 mmol/L). Even after glycemic control improved, TG remained high. After pemafibrate administration, TG decreased to 200 mg/dL (2.3 mmol/L). All patients showed no serious adverse events. CONCLUSIONS: Pemafibrate demonstrated potential efficacy and safety for severe hypertriglyceridemia which may contribute to the prevention of acute pancreatitis, in a manner that can be easily prescribed and used as an oral tablet.

RESUMO

BACKGROUND: To investigate the dynamic change of lipid profile under double filtration plasmapheresis (DFPP) in severe hypertriglyceridemia-induced acute pancreatitis (sHTGP) patients and ascertain the association between these changes and the clinical prognosis. METHODS: sHTGP patients admitted within 72 h after disease onset were included, and all the patients received DFPP within 24 h after admission. Lipid profile were detected on admission, consecutive 4 days after DFPP and at discharge. RESULTS: There were 47 sHTGP patients enrolled in this study. At admission, all the parameters of lipid profile changed significantly except for low density lipoprotein. In the first day after DFPP, the serum level of TG, cholesterol and very low density lipoprotein declined significantly, while the high-density lipoprotein (HDL) as well as apoprotein A1 elevated obviously (P < 0.05). TG maintained the downward trend in the following three days and the other parameters kept steady. Linear regression analysis showed that HDL was negatively correlated with the duration of hospitalization among three adjusted models (P = 0.043, P = 0.029, P = 0.025 respectively). CONCLUSION: There was distinct fluctuation of the lipid profile upon the burst of sHTGP and the parameters changed significantly in the first day after DFPP. Among these parameters, HDL may serve as a biomarker for disease prognosis in patients with sHTGP.

RESUMO

BACKGROUND: Hypertriglyceridemia is often observed as the result of lipid abnormality and frequently associated with other lipid and metabolic disorders. Aggravation of hypertriglyceridemia is caused by various conditions. However, severe hypertriglyceridemia is usually induced by an addition of some secondary clinical conditions such as uncontrolled type 2 diabetes mellitus (T2DM) and obesity with insulin resistance. CASE PRESENTATION: A 40-year-old man with 4-year history of dyslipidemia and T2DM visited after his interruption of therapy for about 1.5 years. His past history was acute pancreatitis. His life style was markedly disturbed, and he had a lot of risk factors for hypertriglyceridemia. Surprisingly, his serum triglyceride level was as high as 16,900 mg/dL. His aggravation and remission of hypertriglyceridemia were closely associated with the alteration of RLP-cholesterol levels in dyslipidemia and glycoalbumin and ketone body levels in T2DM. CONCLUSION: We report very severe hypertriglyceridemia, which seemed to be caused by markedly disturbed life style and poorly controlled T2DM. Total therapy with diet and drug for each disease is very important for the improvement of very severe hypertriglyceridemia. This case report suggests that very severe hypertriglyceridemia alone does not necessarily bring out acute pancreatitis, although it is very important to check pancreatitis markers in such a situation.

RESUMO

The triad of pancreatitis, hypertriglyceridemia, and diabetic ketoacidosis and its treatment has not been extensively discussed in the pediatric literature. We report a 4-year-old child with severe hypertriglyceridemia, pancreatitis, and diabetic ketoacidosis. Hypertriglyceridemia and pancreatitis with diabetic ketoacidosis can be successfully managed with insulin and hydration therapy in children. Early recognition of this triad is important as insulin requirements, recovery duration, and prognosis can be altered.

RESUMO

During pregnancy physiological changes occur in the lipid metabolism due to changing hormonal conditions: the LDL cholesterol (LDL-C), triglycerides (TG) and lipoprotein(a) [Lp(a)] increase throughout pregnancy. Common lipoprotein disorders are associated in pregnancy with two major clinical disorders: severe hypertriglyceridemia (SHTG) is a potent risk factor for development of acute pancreatitis and elevated cholesterol due to greater concentrations of LDL and remnant lipoproteins and reduced levels of HDL promote atherosclerosis. The combination of homozygous Familial Hypercholesterolemia (HoFH) and pregnancy can be a fatal condition. Therapeutic plasma exchange (TPE) may be used for an urgent need of a fast and effective lowering of TG levels in order to prevent a severe pancreatitis episode or hypertriglyceridemia-induced complications during pregnancy. LDL apheresis can decrease LDL-C and prevent complications and can be considered in the treatment of pregnancies complicated by high LDL-C. These conditions are configured in patients with HeFH who were taking statins before pregnancy (selected cases), patients already receiving apheresis before pregnancy suffering from HoFH, patients suffering from hypertriglyceridemia due to familial hyperlipoproteinemia types I and V, and cases of hypertriglyceridemia secondary to diabetes.

RESUMO

BACKGROUND: The antisense oligonucleotide against APOC3 mRNA volanesorsen was recently introduced to treat Familial Chylomicronemia Syndrome (FCS). Cases of decreased platelet count are reported among patients treated with volanesorsen. The aim of the study was to evaluate platelet function and thrombin generation (TG) assessment in FCS patients receiving volanesorsen. We performed a cross-sectional study on FCS patients treated with volanesorsen. METHODS: Changes in platelet count PLC were assessed from baseline to Tw12 and Tw36. To assess TG, samples were processed by CAT (with PPP-reagent LOW). The results were expressed by the thrombogram graphic (thrombin variation over time); LagTime; endogenous thrombin potential (ETP); peak; time to reach peak (ttpeak), StartTail and Velocity Index. Platelet aggregation was assessed by testing different agonists using the turbidimetry method. RESULTS: Four FCS patients and four matched healthy controls were included in the present study. Changes in PLC were 30% at Tw12 and 34% at Tw36. Thrombin generation results showed values in the normal range (for patients and controls, respectively, LagTime:10.42 ± 4.40 and 9.25 ± 0.99; ttPeak:14.33 ± 4.01 and 13.10 ± 0.67; StartTail: 32.13 ± 3.54 and 29.46 ± 1.69; Velocity Index: 20.21 ± 3.63 and 33.05 ± 13.21; ETP: 599.80 ± 73.47 and 900.2 ± 210.99; peak value: 76.84 ± 1.07 and 123.30 ± 39.45) and no significant difference between cases and controls. Platelet aggregation test showed values in range, with no significant difference compared to healthy controls. CONCLUSIONS: Our study showed for the first time that no significant changes in general hemostasis assessed by TG and in platelet function were observed in FCS patients receiving volanesorsen.

RESUMO

INTRODUCTION: Acute hypertriglyceridemia is considered a category III indication for plasmapheresis. The use of plasma as replacement fluid (RF) has been suggested to replace the consumed lipoprotein lipase. Heparin when used as an anticoagulant could possibly release lipoprotein lipase, thereby increasing triglyceride clearance. METHODS: The impact of RF (albumin vs fresh frozen plasma (FFP) and anticoagulant (ACD-A vs. heparin) on triglycerides following plasmapheresis in 27 patients with severe hypertriglyceridemia (SHTG) was investigated. A paired study of four patients with recurrent SHTG was conducted, evaluating continuous (Optia) versus intermittent flow plasmapheresis (Haemonetics). RESULTS: Shorter procedures positively impacted triglycerides (TG) drop post-sessions p < 0.05. In albumin sessions, patients who used heparin demonstrated significantly greater drop in TG and required less sessions than did those with citrate p < 0.05. In heparin sessions, patients who used albumin demonstrated significantly greater drop in triglycerides and required less sessions than did those with FFP p < 0.05. Three of six patients who used FFP and heparin showed a triglyceride drop of 11.7% following three sessions and a 50% drop with one albumin session. Compared with Haemonetics, Optia removed comparable volumes of plasma in less time, processing smaller blood volumes and using less citrate p < 0.05. Patients demonstrated significantly lower drop in TG and required more sessions with Haemonetics than they did with Optia p < 0.05. CONCLUSION: Shorter procedure was the main predictor for effective TG clearance. This can be achieved by continuous apheresis technology, particularly when using albumin as RF. TG removal via Optia seems to be optimized by using heparin.

RESUMO

BACKGROUND AND AIMS: Multifactorial chylomicronemia syndrome (MCS) is a severe form of hypertriglyceridemia (hyperTG) associated with an increased risk of acute pancreatitis (AP). Severe hyperTG is mainly polygenic in nature, either caused by the presence of heterozygous pathogenic variants (PVs) in TG-related metabolism genes or by accumulation of common variants in hyperTG susceptibility genes. This study aims to determine if the risk of AP is similar amongst MCS patients with different molecular causes of severe hyperTG. METHODS: This study included 114 MCS patients who underwent genetic testing for PVs in TG-related metabolism genes and 16 single nucleotide polymorphisms (SNPs) in hyperTG susceptibility genes. A weighted TG-polygenic risk score (TG-PRS) was calculated. A TG-PRS score ≥ 90th percentile was used to define a high TG-PRS. RESULTS: Overall, 66.7% of patients had severe hyperTG of polygenic origin. MCS patients with only a PV and those with both a PV and high TG-PRS were more prone to have maximal TG concentration ≥ 40 mmol/L (OR 5.33 (1.55-18.36); p = 0.008 and OR 5.33 (1.28-22.25); p = 0.02), as well as higher prevalence of AP (OR 3.64 (0.89-14.92); p = 0.07 and OR 11.90 (2.54-55.85); p = 0.002) compared to MCS patients with high TG-PRS alone. CONCLUSIONS: This is the first study to show that MCS caused by a high TG-PRS and a PV is associated with higher risk of AP, similar to what is seen in the monogenic form of severe hyperTG. This suggests that determining the molecular cause of severe hyperTG could be useful to stratify the risk of pancreatitis in MCS.

RESUMO

Hypertriglyceridemia (HTG) is a common dyslipidemia associated with an increased risk of cardiovascular disease and pancreatitis. It is well stablished that the severe cases of disease often present with an underlying genetic cause. In this study, we determined the frequency and variation spectrum of genes involved in the triglyceride metabolism in a series of Brazilian patients with severe HTG. A total of 212 patients with very high HTG, defined with fasting triglycerides (TG) ≥ 880 mg/ dL, that underwent a multi-gene panel testing were included in this research. Germline deleterious variants (i.e. Pathogenic/Likely Pathogenic (P/LP) variants) were identified in 28 out of 212 patients, reflecting an overall diagnostic yield of 13% in our cohort. Variants of unknown significance (VUS) were identified in 87 patients, and represent 80% of detected variants in this dataset. We confirm the LPL as the most frequently mutated gene in patients with severe HTG, and we had only one suspected case of familial chylomicronemia syndrome, caused by a homozygous variant in LMF1, in our cohort. Notably, we report 16 distinct and novel variants (P/LP and VUS), each of them representing a single case, not previously reported in any public databases or other studies. Our data expand our knowledge of genetic variation spectrum in patients with severe HTG in the Brazilian population, often underrepresented in public genomic databases, being also a valuable clinical resource for genetic counseling and healthcare programs in the country.

RESUMO

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.

RESUMO

BACKGROUND: Teleconsultation in the context of clinical laboratories is a valuable tool for the early detection of dyslipidemia and prevention of cardiovascular risk. Here, we describe a patient who was referred to the Lipid Unit of the Virgen Macarena Hospital due to an alert for severe hypertriglyceridemia through its teleconsultation program. CASE PRESENTATION: A comprehensive clinical and biochemical study of the patient was carried out, and genetic testing was performed on the patient and his family. The proband and his family showed mild to severe hypertriglyceridemia and various secondary factors, together with a genetic background associated with a triglyceride-raising effect. CONCLUSION: This extensive study has identified a family at high risk of cardiovascular disease and acute pancreatitis. These findings can help maximize lifestyle changes and improve the clinical management of their dyslipidemia.

RESUMO

Omega-3-acid ethyl acetate 90 capsules (containing 465 mg of eicosapentaenoic acid and 375 mg docosahexaenoic acid) is composed of highly purified omega-3 polyunsaturated fatty acid (PUFA) ethyl esters, whose lipid-lowering effect for severe hypertriglyceridemia (HTG) treatment is unclear. This study aimed to evaluate the efficacy and safety of omega-3-acid ethyl acetate 90 capsules in patients with severe HTG. In this randomized, double-blind, placebo-controlled, multicenter study, 239 patients with severe HTG were enrolled and randomized (1:1) into omega-3 group (N = 122) and placebo group (N = 117) to receive 12-week corresponding treatments. Lipid-related indexes were obtained at treatment initiation (W0), 4 weeks (W4), W8, and W12 after treatment. Adverse events and adverse drug reactions were recorded. Triacylglycerols (TAG), total cholesterol (TC), non-high-density lipoprotein cholesterol (non-HDL-C), very-low-density lipoprotein cholesterol (VLDL-C), and apolipoprotein C-III (Apo C-III) at W4, W8, and W12 were decreased in the omega-3 group versus the placebo group (all p < 0.05). Moreover, the percentage changes of TAG, TC, non-HDL-C, and VLDL-C from W0 to W4, W8, and W12, and the percentage change of Apo C-III from W0 to W4 and W8, were more obvious in the omega-3 group compared with the placebo group (all p < 0.05). However, no difference was observed in the percentage changes of HDL-C, low-density lipoprotein cholesterol (LDL-C), and LDL-C/HDL-C ratio during follow-up between groups (all p > 0.05). Additionally, there was no discrepancy in adverse events and adverse drug reactions between groups (all p > 0.05). Omega-3-acid ethyl acetate 90 capsules exhibit satisfied lipid-lowering effect with tolerable safety profile in patients with severe HTG.

RESUMO

We present a rare case of a 52-year-old male with asymptomatic severe hypertriglyceridemia exceeding 11,000 mg/dL, managed initially with oral therapy without the need for an insulin drip or plasmapheresis. However, due to non-compliance at home, the patient subsequently developed pancreatitis requiring treatment with an insulin drip. He was discharged on a regimen of fenofibrate, rosuvastatin, and omega-3, with no further episodes of symptoms. Asymptomatic patients with severe hypertriglyceridemia and a low risk of developing symptoms can be safely managed through close monitoring, statin, fibrate therapy, and lifestyle modifications, but the risk of acute pancreatitis persists with elevated triglyceride levels of over 500 mg/dL and a marked increase in risk with a triglyceride level of greater than 880 mg/dL.
