Treatment of severe hypertriglyceridemia through therapeutic plasma exchange in patients with acute pancreatitis or at risk of developing it. / Tratamiento de la hipertrigliceridemia grave mediante recambio plasmático terapéutico en pacientes con pancreatitis aguda o en riesgo de padecerla.

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.

Early detection of severe hypertriglyceridemia using teleconsultation in a clinical laboratory setting.

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.

Hipertrigliceridemia asociada a resistencia a la insulina en niños con obesidad / Hypertriglyceridemia associated with insulin resistance in children with obesity

RESUMEN Introducción: La hipertrigliceridemia se ha vinculado con la resistencia a la insulina. Objetivos: Evaluar la relación y capacidad predictiva de la hipertrigliceridemia para la resistencia a la insulina en niños obesos. Métodos: Se realizó un estudio transversal y analítico en niños de 6 a 14 años con obesidad, atendidos en el Hospital Belén de Trujillo entre 2014 y 2019. Se analizaron 58 historias clínicas elegidas aleatoriamente. La resistencia a la insulina se midió mediante el índice Homeostasis Model Assessment (HOMA) (≥3). Se usaron análisis descriptivos, correlacionales y cálculos de Odds Ratio (OR), además de indicadores de predicción como sensibilidad y especificidad. Resultados: De los 58 niños estudiados, el 58,6% presentaba niveles elevados de triglicéridos y el 74,1% mostró resistencia a la insulina. Hubo una correlación significativa entre los niveles de triglicéridos y el índice HOMA (coef.: 0,543; p<0,001). Los niveles elevados de triglicéridos (OR=18,91; IC 95%: 3,67-97,36; p<0,001), glicemia en ayunas (OR=46,20; IC 95%: 5,39-396,06; p=0,010), de insulina en ayunas (OR=52,89; IC 95%: 6,11-457,55; p<0,001) y la presencia de acantosis nigricans (OR=36,17; IC 95%: 4,28-305,98; p<0,001) se asociaron significativamente con la resistencia a la insulina. La hipertrigliceridemia mostró una sensibilidad del 74,4% y una especificidad del 86,7% para predecir la resistencia a la insulina. Conclusión: La hipertrigliceridemia está significativamente asociada con la resistencia a la insulina en niños obesos y tiene un rendimiento aceptable como predictor de la misma. Este factor puede servir como un marcador temprano y predictor para implementar medidas preventivas adecuadas en poblaciones vulnerables.

ABSTRACT Introduction: Hypertriglyceridemia has been linked to insulin resistance. Objectives: To evaluate the relationship and predictive capacity of hypertriglyceridemia for insulin resistance in obese children. Methods: A cross-sectional analytical study was conducted in obese children aged 6 to 14 years, treated at the Belén Hospital of Trujillo between 2014 and 2019. Fifty-eight randomly selected medical records were analyzed. Insulin resistance was measured using the Homeostasis Model Assessment (HOMA) index (≥3). Descriptive, correlational analyses, and Odds Ratio (OR) calculations were used, along with predictive indicators such as sensitivity and specificity. Results: Of the 58 children studied, 58.6% had elevated triglyceride levels and 74.1% showed insulin resistance. There was a significant correlation between triglyceride levels and the HOMA index (coef.: 0.543; p<0.001). Elevated triglyceride levels (OR=18.91; 95% CI: 3.67-97.36; p<0.001), fasting glucose (OR=46.20; 95% CI: 5.39-396.06; p=0.010), fasting insulin (OR=52.89; 95% CI: 6.11-457.55; p<0.001), and the presence of acanthosis nigricans (OR=36.17; 95% CI: 4.28-305.98; p<0.001) were significantly associated with insulin resistance. Hypertriglyceridemia showed a sensitivity of 74.4% and a specificity of 86.7% for predicting insulin resistance. Conclusion: Hypertriglyceridemia is significantly associated with insulin resistance in obese children and has an acceptable performance as a predictor. This factor may serve as an early marker and predictor to implement appropriate preventive measures in vulnerable populations.

[The importance of genetics in the study of hypertriglyceridemia]. / La importancia de la genética en el estudio de la hipertrigliceridemia.

Hypertriglyceridemia encompasses a set of lipid disorders common in clinical practice, generally defined as a fasting concentration above 150mg/dL. There are various classifications of the severity of hypertriglyceridaemia based on serum values, with levels generally considered moderate when below 500mg/dL and severe when above 1000mg/dL. Its importance lies in its association with other alterations in the lipid profile, contributing to increased cardiovascular risk and increased risk of acute pancreatitis, mainly with concentrations above 500mg/dL.

Hipertrigliceridemia grave en Argentina: prevalencia y características clínicas / Severe Hypertriglyceridemia in Argentina: Prevalence and Clinical Characteristics

RESUMEN Introducción : La hipertrigliceridemia grave (HTGG) es un desorden metabólico con múltiples causas e implicancias tera péuticas. Se desconocen hasta la fecha las características clínicas, la prevalencia y sus posibles causas en nuestra población. Objetivo : estimar la prevalencia, describir las características clínicas y causas subyacentes de la HTGG en un hospital de tercer nivel del municipio de General Pueyrredón. Materia y métodos : Estudio descriptivo y observacional realizado con pacientes ambulatorios e internados de un hospital provincial. Se incluyeron pacientes adultos con triglicéridos (TG) mayores que 885 mg/dL (10 mmol/L) evaluados desde enero de 2018 a diciembre de 2021. Se extrajeron sus historias clínicas y, luego, se los contactó para obtener medidas antro pométricas, variables sociodemográficas, antecedentes personales y familiares, causas secundarias de hipertrigliceridemia y el tratamiento recibido. Resultados : Se analizaron 16 029 muestras; 46 presentaron HTGG, lo que representa una prevalencia total del 0,28% (IC 95% 0,20-0,40%) (IC 95% 0,20-0,40%); se incluyeron 19 participantes en el análisis. La edad media fue de 48,47 años (DE ±16); el 84,2% de ellos eran hombres. La mediana de triglicéridos fue 1821 mg/dL (rango intercuartílico 917-7000 mg/dL); 17 participantes (84,97%) presentaban hipercolesterolemia (colesterol total mayor que 200 mg/dL). Casi el 50% refirió consumo de alcohol, el 55% presentaba obesidad y el 68% diabetes tipo II. Solo 9 participantes se encontraban en tratamiento, 4 con fibratos y 5 con estatinas. Conclusión : se encontró una prevalencia del 0,28%, más alta que la esperada y reportada en series previas. Por otro lado, se destaca la subutilización de medicación para el tratamiento de esta dislipidemia grave.

ABSTRACT Background : Severe hypertriglyceridemia (SHTG) is a metabolic disorder with multiple origins and management implications. Prevalence, clinical characteristics, and its possible causes are unknown in Argentina. Objective : The aim of this study was to estimate the prevalence and describe the clinical characteristics and underlying SHTG causes in a third level hospital in the municipality of General Pueyrredón. Methods : An observational, descriptive study was performed using an electronic database from a provincial Hospital. It included adult patients with triglyceride (TG) levels above 885 mg/dL (10 mmol/L) evaluated from January 2018 to December 2021. Medical records were collected, and patients were then contacted to obtain anthropometric measurements, sociodemographic variables, personal and family history, secondary causes of hypertriglyceridemia, and treatment received. Results : Among 16 029 patients analyzed, 46 presented SHTG, representing a total prevalence of 0.28% (95% CI 0.20-0.40%). Finally, 19 participants with mean age 48.47±16 years and 84.2% men were included in the analysis. Median TG level was 1821 mg/dL (interquartile range 917-7000 mg/dL), and 17 participants (84.97%) had hypercholesterolemia (total cholesterol >200 mg/dL). Almost 50% reported alcohol consumption, 55% were obese and 68% had type II diabetes. Nine participants were under pharmacological treatment, 4 with fibrates and 5 with statins. Conclusion : A prevalence of 0.28% SHTG was found, higher than that reported in other series. Another finding was the underuse of medication for this severe dyslipidemia.

Influence of enlarged waist circumference and hypertriglyceridemia in the severity of acute pancreatitis: A retrospective study.

INTRODUCTION: Acute pancreatitis is a frequent inflammatory gastrointestinal disorder with high mortality rates in severe forms. An early evaluation of its severity is key to identify high-risk patients. This study assessed the influence of waist circumference together with hypertriglyceridemia on the severity of acute pancreatitis. METHODS: A retrospective study was performed, which included patients admitted with acute pancreatitis from March 2014 to March 2021. Patients were classified into four phenotype groups according to their waist circumference and triglyceride levels: normal waist circumference and normal triglycerides; normal waist circumference and elevated triglycerides; enlarged waist circumference and normal triglycerides; and enlarged waist circumference and triglycerides, namely hypertriglyceridemic waist (HTGW) phenotype. Clinical outcomes were compared among the groups. RESULTS: 407 patients were included. Systemic inflammatory response syndrome (SIRS) and intensive care unit admission were most frequent among patients in the HTGW phenotype group, at 44.9% and 8.2%, respectively. The incidence of local complications was higher in the normal waist circumference with elevated triglycerides group (27%). On multivariable analysis, an enlarged waist circumference was related to an increase of 4% and 2% in the likelihood of developing organ failure and SIRS, respectively. Hypertriglyceridemia was an independent risk factor for both organ failure and local complications. CONCLUSIONS: HTGW phenotype was significant related to developing of SIRS. It seems that an enlarged waist circumference has a greater role than hypertriglyceridemia in the development of SIRS. Obesity and hypertriglyceridemia were both independent risk factors for organ failure. Patients with hypertriglyceridemia were more likely to develop local complications.

Nutritional recommendations in the prevention and treatment of atherogenic dyslipidemia. / Recomendaciones nutricionales en la prevención y tratamiento de la dislipemia aterogénica. Grupo de Trabajo Dislipemia Aterogénica, Sociedad Española de Arteriosclerosis.

The incorporation of a healthy diet, regular physical exercise and smoking cessation are the initial measures to reduce cardiovascular risk in patients with atherogenic dyslipidemia. In these patients, the nutritional quality of their diet should be improved, replacing foods with a greater atherogenic effect for others with a healthier effect. There is strong evidence that plant-based dietary patterns, low in saturated fatty acids, cholesterol and sodium, with a high content of fiber, potassium and unsaturated fatty acids, are beneficial and reduce the expression of cardiovascular risk factors. This document focuses on the role of nutrition in the prevention and treatment of atherogenic dyslipidemia, providing current evidence to serve as a tool for health professionals in its clinical management. To facilitate the reading of these recommendations, they are presented in a user-friendly table format, with a hierarchy of different levels of evidence.

Association of rs662799 and rs5070 genetic polymorphisms with hypertriglyceridemia and atherogenic dyslipidemia in pediatric patients in Southeast Mexico.

BACKGROUND AND AIMS: Triglycerides are the initiators of the metabolic changes that lead to atherogenic dyslipidemia (AD). The APOA5 and APOA1 genes are involved in the response and metabolism of serum lipids and lipoproteins, where single nucleotide polymorphisms (SNP) rs662799 (promoter region) and rs5070 (intronic region) have been associated with the susceptibility to dyslipidemia. Until now, few studies evaluate the association of these polymorphisms with the presentation of hypertriglyceridemia and AD among Mexican children. Therefore, the objective was to determine the association between rs662799 and rs5070 with hypertriglyceridemia and AD in a pediatric population of southeastern Mexico. MATERIALS AND METHODS: A case-control analysis was performed including 268 infants aged 2-16 years, anthropometric, clinical variables, and serum lipid profiles were analyzed. DNA was extracted from blood samples and genotyping of polymorphisms was executed with the TaqMan SNP genotyping assay. Allele and genotypic frequencies were calculated. For genetic association analysis, logistic regression models were fitted according to models of inheritance. RESULTS: The SNP rs662799 (C) was significantly associated with hypertriglyceridemia in the overdominant model (OR=3.89, p=0.001) and AD in the dominant model (OR=4.01, p=0.001). The SNP rs5070 (T) has a protective effect against hypertriglyceridemia in the additive risk model (OR=0.68, p=0.03). CONCLUSION: Polymorphism rs662799 was significantly associated with cases of hypertriglyceridemia and AD in minors in southeastern Mexico. On the other hand, rs5070 polymorphism was not associated with cases of hypertriglyceridemia or AD.

Treatment of hypertriglyceridaemia with icosapent ethyl in patients with high/very high cardiovascular risk. Consensus document of the Sociedad Española de Cardiología [Spanish Society of Cardiology] and the Sociedad Española de Diabetes [Spanish Diabetes Society].

The Working Groups of Cardiovascular Pharmacotherapy of the Sociedad Española de Cardiología and Cardiovascular Disease of the Sociedad Española de Diabetes have prepared a consensus document on the treatment of hypertriglyceridaemia in patients with high/very-high-cardiovascular risk with icosapent ethyl, a highly purified and stable eicosapentaenoic acid ethyl ester. This document is necessary since there are differences among the three main omega-3 fatty acids and there is large-scale clinical evidence with icosapent ethyl that demonstrates that in addition to its efficacy in lowering triglyceridaemia, it reduces the risk of cardiovascular events in both patients with atherosclerotic cardiovascular disease and in those with type 2 diabetes, with a good safety profile. The number needed to treat to avoid a major cardiovascular event is analysed, comparing it with other pivotal studies of pharmacological intervention in cardiovascular prevention, and an estimate of the Spanish population likely to be treated with ethyl icosapent is carried out. These recommendations are of interest to all clinicians who manage patients with lipid metabolism disorders, cardiovascular disease and diabetes.

Pancreatitis aguda por hipertrigliceridemia severa, caracterización en un hospital terciario / Acute pancreatitis due to severe hypertriglyceridemia, characterization in a tertiary hospital

La hipertrigliceridemia severa es una de las principales causas etiológicas de la pancreatitis aguda, donde la literatura internacional la posiciona como la tercera causa. Sus causas gatillantes, comorbilidades, severidad y evolución son importantes de conocer para evitar futuros episodios. En Chile, a nuestro entender, no tenemos literatura sobre esta asociación, por lo que presentamos datos de un hospital terciario, destacando 15 casos de pancreatitis aguda en 5 años de estudio, casi la mitad de ellos con antecedentes previos de hipertrigliceridemia, un porcentaje importante de los casos con cuadros graves y con complicaciones intrahospitalarias y que la diabetes mellitus tipo 2 fue la principal condición asociada a la hipertrigliceridemia severa.

Severe hypertriglyceridaemia is one of the main aetiological causes of acute pancreatitis, with international literature ranking it as the third leading cause. Its triggering causes, comorbidities, severity and evolution are important to know in order to avoid future episodes. In Chile, to our knowledge, we have no literature on this association, so we present data from a tertiary hospital, highlighting 15 cases of acute pancreatitis in 5 years of study, almost half of them with a previous history of hypertriglyceridaemia, a significant percentage of cases with severe symptoms and in-hospital complications, and that type 2 diabetes mellitus was the main condition associated with severe hypertriglyceridaemia.

Se realizó medición de peso, talla, circunferencia de cintura (CC), glicemia, perfil lipídico y presión arterial. Para el diagnóstico de SM se utilizó los criterios de Cook. Aprobado por el Comité de Ética del IICS y del Hospital de Clínicas. Para el análisis se utilizaron tablas de frecuencias, mediana y Prueba del Chi cuadrado para razón de prevalencias (RP) con nivel de significancia p p90 36%. La prevalencia de SM fue del 10,7 %. La CC >p90 con RP de 31,4 (7,6-128), y la hipertrigliceridemia con RP de 46,8(14,8-147,7), fueron los componentes preponderantes de SM. El peso elevado al nacer y no realizar actividad física, fueron identificados como factores de riesgo significativo. Conclusiones: La prevalencia de SM fue 10,7%, se relacionó con mayor peso al nacimiento, obesidad y sedentarismo.

Introduction: Metabolic Syndrome (MS) is a clinical entity that is manifested by central obesity, dyslipidemia, hyperglycemia and/or arterial hypertension and is related to the development of Type 2 Diabetes Mellitus and cardiovascular diseases. Objective: To determine the prevalence of MS in adolescents enrolled in school in the Central Department in 2021 and to evaluate their related risk factors. Materials and Methods: This was a descriptive study with an analytical component. 279 adolescents aged 10 to 16 years old from 6 randomly chosen schools were included. A survey on lifestyles, eating practices, family and perinatal history was performed. Weight, height, waist circumference (WC), glycemia, lipid profile, and blood pressure were measured. Cook's criteria were used for the diagnosis of MS. The study was approved by the Ethics Committee of the IICS and the University Hospital. For data analysis, tables of frequencies, median and Chi-square test were used for the prevalence ratio (PR) with a significance level of p p90 in 36%. The prevalence of MS was 10.7%. WC >p90 with a PR of 31.4 (7.6-128), and hypertriglyceridemia with a PR of 46.8 (14.8-147.7), were the predominant components of MS. High birth weight and physical inactivity were identified as significant risk factors. Conclusions: The prevalence of MS was 10.7%, it was related to higher birth weight, obesity and sedentary lifestyle.

Familial chylomicronemia syndrome: The first case reported in Ecuador. / Síndrome de quilomicronemia familiar: primer caso reportado en Ecuador.

Familial chylomicronemia syndrome (FCS) is a genetic entity with autosomal recessive inheritance. Mutations in genes (such as APOC2, APOAV, LMF-1, GPIHBP-1) that code for proteins that regulate the maturation, transport, or polymerization of lipoprotein lipase-1 are the most common causes, but not the only ones. The objective of this study was to report the first documented case in Ecuador. CLINICAL CASE: A 38-year-old man presented with chronic hepatosplenomegaly, thrombocytopenia, pancreatic atrophy, and severe hypertriglyceridemia refractory to treatment. A molecular analysis was performed by next generation sequencing that determined a deficiency of Lipoprotein Lipase OMIM #238600 in homozygosis. Genetic confirmation is necessary in order to establish the etiology of HTGS for an adequate management of this pathology.

[Parenteral nutrition-associated complications in patients with SARS-CoV-2 infection]. / Complicaciones asociadas a la nutrición parenteral en los enfermos con infección por SARS-CoV-2.

Introduction: Background: it is unknown whether patients with acute respiratory distress syndrome (ARDS) secondary to COVID-19 are at greater risk of developing complications associated with parenteral nutrition (PN). Aim: to describe the incidence, risk factors, and clinical impact of complications in patients with ARDS-COVID-19 receiving PN. Methods: a prospective cohort study of 87 patients with ARDS-COVID-19 infection. The incidence of complications and odds ratios of risk factors were analysed. Results: age ≥ 65 years (OR, 2.52, 95 % CI: 1.16 to 5.46), obesity (OR, 3.34, 95 % CI: 2.35 to 4.33) and treatment with propofol (OR, 2.45, 95 % CI: 1.55 to 3.35) or lopinavir/ritonavir (OR, 4.98, 95 % CI: 3.60 to 6.29) were risk factors for hipertriglyceridemia. Obesity (OR, 3.11, 95 % CI: 1.10 to 8.75), dyslipidemia (OR, 3.22, 95 % CI: 1.23 to 8.40) or treatment with propofol (OR, 5.47, 95 % CI: 1.97 to 15.1) were risk factors for intravascular catheter-related infection. No risk factors were described for hiperglycemia. Mortality was higher in patients with intravascular catheter-related infection (46.7 % vs 10.8 %, p = 0.014). Mortality risk was higher in older patients (OR, 2.74, 95 % CI: 1.08 to 6.95) or patients with intravascular catheter-related infection (OR, 3.22, 95 % CI: 1.23 to 8.40). Conclusions: the incidence of complications associated with PN in patients with COVID-19-related ARDS is frequent. The mortality risk is higher in older patients or those with catheter-related infection.

Los pacientes con obesidad (OR: 3,11, IC 95 %: 1,10 a 8,75) o dislipemia (OR: 3,22, IC 95 %: 1,23 a 8,40) y los tratados con propofol (OR: 5,47, IC 95 %: 1,97 a 15,1) presentaron mayor riesgo de infección asociada al catéter (IAC). No se observó ningún factor de riesgo relacionado con el desarrollo de hiperglucemia. La mortalidad fue mayor en los pacientes con IAC (46,7 % vs. 10,8 %, p = 0,014). El riesgo de mortalidad fue superior en los enfermos de ≥ 65 años (OR: 2,74, IC 95 %: 1,08 a 6,95) o con IAC (OR: 3,22, IC 95 %: 1,23 a 8,40). Conclusiones: la incidencia de complicaciones asociadas a la NP en pacientes diagnosticados de infección por SARS-CoV-2 es elevada. El riesgo de mortalidad es superior en los enfermos mayores de 65 años o con IAC.

Frecuencia del fenotipo de cintura hipertrigliceridémica y su asociación con anormalidades metabólicas en adolescentes de una región andina del Perú / Frequency of hypertriglyceridemic waist phenotype and its association with metabolic abnormalities in adolescents from a Andean region of Peru

RESUMEN Introducción. La cintura hipertrigliceridémica ha sido propuesta como un fenotipo con una fuerte asociación al síndrome metabólico, no se conoce la frecuencia de este fenotipo en adolescentes del Perú, incluyendo sus zonas andinas. Objetivo. Estimar la frecuencia de la cintura hipertrigliceridémica y su asociación con anormalidades metabólicas y otros factores en adolescentes peruanos de una región andina. Métodos. Estudio de fuente secundaria de diseño transversal analítico. Analizamos los datos de 397 adolescentes seleccionados aleatoriamente en dos escuelas públicas de la ciudad de Cajamarca. Se definió cintura hipertrigliceridémica como la presencia simultánea de una circunferencia de cintura incrementada (≥percentil 90 para edad y sexo) e hipertrigliceridemia sérica (≥110 mg/dL). Se realizó la estimación de la prevalencia de manera puntual y con su intervalo de confianza al 95%, también realizamos un análisis de regresión logística binaria para identificar factores asociados. Resultados. El fenotipo de cintura hipertrigliceridémica fue 2,01% (IC95%: 0,51 a 3,52). El componente más frecuente fue hipertrigliceridemia con 39,55% (IC95%: 34,61 a 44,48), mientras que la circunferencia de cintura incrementada afectó al 3,02% (IC95%: 1,21 a 4,83). El exceso de peso fue la única variable asociada con el fenotipo de cintura hipertrigliceridémica (OR ajustado: 62,7; IC95%: 6,7 a 587,9; p<0,001). Conclusiones. Dos de cien adolescentes de 11 a 17 años residentes de una región altoandina del Perú tuvieron el fenotipo de cintura hipertrigliceridémica. Dicho fenotipo estuvo asociado con el exceso de peso.

ABSTRACT Introduction. The hypertriglyceridemic waist has been proposed as a phenotype with a strong association with the metabolic syndrome. The frequency of this phenotype in adolescents from Peru, including Andes population is unknown. Objective. To estimate the frequency of the hypertriglyceridemic waist and its association with metabolic abnormalities and other factors in Peruvian adolescents from an Andean region. Methods. We performed a data secondary analysis through cross-sectional design. We analyzed 397 randomly selected adolescents from two public schools in the Cajamarca city. We defined hypertriglyceridemic waist as the simultaneous presence of increased waist circumference (≥ 90th percentile for age and sex) and serum hypertriglyceridemia (≥110 mg/dL). We estimated the point prevalence of hypertriglyceridemic waist and their 95% confidence interval, we also performed a binary logistic regression analysis to identify associated risks. Results. The phenotype of hypertriglyceridemic waist was 2.01% (95%CI: 0.51 to 3.52). The most frequent component was hypertriglyceridemia with 39.55% (95%CI: 34.61 to 44.48), while increased waist circumference affected 3.02% (95%CI: 1.21 to 4.83). Excess weight was the only variable association with hypertriglyceridemic waist phenotype (adjusted OR: 62.7; 95%CI: 6.7 - 587.9; p<0.001). Conclusions. Two of one hundred adolescents aged 11 to 17 years living in a high Andean region of Peru had the hypertriglyceridemic waist phenotype. This phenotype was associated with excess weight.

Bempedoic acid as a PPARα activator: new perspectives for hepatic steatosis treatment in a female rat experimental model. / El ácido bempedoico como activador PPARα: Nuevas perspectivas para el tratamiento de la esteatosis hepática en un modelo experimental de rata hembra.

INTRODUCTION: In its initial stages, nonalcoholic fatty liver disease presents hypertriglyceridemia and accumulation of lipids in the liver (hepatic steatosis). Bempedoic acid is an ATP:citrate lyase inhibitor that promotes a dual inhibition of the synthesis of cholesterol and fatty acids. However, its effect in the prevention / treatment of hepatic steatosis and hypertriglyceridemia has not been investigated. The aim of our work has been to elucidate whether bempedoic acid, through a mechanism other than ATP:citrate lyase inhibition, reverses these metabolic alterations. EXPERIMENTAL DESIGN: The study was carried out in female Sprague-Dawley rats fed, for three months, with a high fat diet supplemented with fructose (10% w/v) in drinking water. During the last month, bempedoic acid (30mg/kg/day) was administered to a group of animals. Zoometric and plasmatic parameters were analyzed, gene and protein expression analysis were performed in liver samples and PPAR-PPRE binding activity was determined. RESULTS: Our interventional model developed hepatic steatosis and hypertriglyceridemia. Despite an increase in total caloric intake, there was no increase in body weight of the animals. The administration of bempedoic acid significantly reduced hepatic steatosis and promoted a marked hepatocyte hypertrophy. There was a 66% increase in the liver weight of the animals treated with the drug that was not accompanied by modifications in the markers of inflammation, oxidative stress, or endoplasmic reticulum stress. Bempedoic acid activated the peroxisome proliferator activated nuclear receptor (PPARα) and its target genes. CONCLUSIONS: Bempedoic acid could be an effective therapy for the treatment of fatty liver and associated cardiovascular risk. Bempedoic acid has other mechanisms of action besides the inhibition of ATP: citrate lyase, such as the activation of PPARα, which could explain the reduction in hepatic steatosis and the increase in liver weight observed in animals treated with the drug.

Hipertrigliceridemia severa durante el embarazo

Resumen: Durante el embarazo se producen cambios a nivel de la concentración de los lípidos debido a cambios fisiológicos con el fin de favorecer una adecuada nutrición fetal, estos cambios rara vez tienen consecuencias clínicas. Se presenta el caso clínico de una gestante que a las 31 semanas de edad gestacional se le diagnostica un estado hipertensivo del embarazo, constatándose hipertrigliceridemia severa con alto riesgo de pancreatitis. Se realizó recambio plasmático terapéutico y gemfibrozilo, con buena respuesta clínica.

Abstract: During pregnancy, changes occur at the level of lipid concentration due to physiological changes in order to promote adequate fetal nutrition, these changes rarely have clinical consequences. The clinical case of a pregnant woman is presented who at 31 weeks of gestational age is diagnosed with a hypertensive state of pregnancy, confirming severe hypertriglyceridemia with a high risk of pancreatitis. Therapeutic plasma exchange and gemfibrozil were performed, with a good clinical response.

Applicability of Martin-Hopkins formula and comparison with Friedewald formula for estimated low-density lipoprotein cholesterol in e_COR study population.

INTRODUCTION: Low-density lipoprotein cholesterol (LDL) is essential in managing cardiovascular disease risk. Since 1972, the Friedewald formula has been used to estimate LDL concentration, although with some limitations. In 2013, Martin et al. proposed a similar but more accurate formula for calculating LDL. AIM: To assess the applicability of the new formula, which we have named the Martin-Hopkins formula, in the Portuguese population and compare it with the Friedewald formula using direct LDL. METHODS: Cross-sectional study, including 1689 participants from the e_COR study. We applied the Martin-Hopkins and Friedewald formulas for estimated LDL (LDL-M and LDL-F). The Friedewald formula was not applied in 12 cases due to triglycerides ≥400mg/dL. Direct LDL was measured and the accepted significance level was p<0.05. RESULTS: Of the total subjects, 50.2% were male and had a median age of 51 (34) years. LDL-D was 117.0 (44.0) mg/dL, LDL-M was 114.6 (43.7) mg/dL and LDL-F was 113.8 (43.2) mg/dL. The Spearman coefficient (ρ) between LDL-M/LDL-D was 0.987 and between LDL-F/LDL-D was 0.983, p=0.001. This strong correlation was maintained in the group with diabetes (LDL-M/LDL-D ρ=0.987; LDL-F/LDL-D ρ=0.978, p=0.001) and hypertriglyceridemia (LDL-M/LDL-D ρ=0.983; LDL-F/LDL-D ρ=0.982, p=0.001). In terms of agreement, the highest value of κ=0.90 was obtained for LDL-M when LDL-D <100mg/dL. CONCLUSION: The Martin-Hopkins formula performed well and had good applicability, showing superiority in relation to the Friedewald formula, especially for LDL-D values <100mg/dL, diabetes, and hypertriglyceridemia.
