Asociación entre los marcadores lipídicos en la infancia/ adolescencia y los eventos cardiovasculares en la adultez: una revisión sistemática / Association between lipid markers in childhood/ adolescence and cardiovascular events in adulthood: A systematic review

Introducción. La asociación entre los marcadores lipídicos en la infancia/adolescencia y la incidencia de eventos clínicos cardiovasculares en la adultez está poco explorada en la literatura. El objetivo de esta revisión sistemática fue analizar la evidencia disponible sobre este tema. Población y métodos. Esta revisión sistemática se realizó de acuerdo con las guías PRISMA. Se realizó una búsqueda bibliográfica para detectar los estudios que evaluaron la asociación entre los niveles lipídicos en la edad pediátrica y la incidencia de eventos cardiovasculares en la edad adulta. No hubo restricciones idiomáticas ni geográficas en la búsqueda. Resultados. En total, cinco estudios observacionales (todas cohortes prospectivas) que incluyeron 43 540 pacientes fueron identificados y considerados elegibles para este estudio. Cuatro estudios evaluaron el nivel de triglicéridos; todos reportaron una asociación significativa entre este marcador en la edad pediátrica y los eventos cardiovasculares en la adultez. Un estudio reportó la misma asociación con el nivel de colesterol total, mientras que otro evidenció el valor predictivo de la lipoproteína (a) para el mismo desenlace clínico. Un solo estudio evaluó el colesterol asociado a lipoproteínas de alta densidad (C-HDL), sin encontrar una relación con el punto final de interés. El análisis del colesterol asociado a lipoproteínas de baja densidad (C-LDL) arrojó resultados contradictorios, aunque la asociación fue significativa en los estudios con un tamaño muestral más grande y con un mayor número de eventos durante el seguimiento. Conclusión. Los datos de esta revisión sugieren que las alteraciones de los marcadores lipídicos en la infancia y la adolescencia se asocian con un mayor riesgo cardiovascular en la adultez temprana y media.

Introduction. The association between lipid markers in childhood/adolescence and the incidence of clinical cardiovascular events in adulthood has been little explored in the bibliography. The objective of this systematic review was to analyze available evidence on this topic. Population and methods. This systematic review was conducted in accordance with the PRISMA guidelines. A comprehensive bibliographic search was done to find studies assessing the association between lipid levels in childhood and the incidence of cardiovascular events in adulthood. There were no language or geographic restrictions. Results. A total of 5 observational studies (all prospective cohorts) including 43 540 patients were identified and considered eligible for this study. Four studies assessed triglyceride levels; all reported a significant association between this lipid marker in childhood and cardiovascular events in adulthood. A study reported the same association with total cholesterol level, while another showed the predictive value of lipoprotein (a) for the same clinical outcome. Only one study assessed high-density lipoprotein cholesterol (HDL-C), but it did not find an association with the endpoint of interest. The analysis of lowdensity lipoprotein cholesterol (LDL-C) showed contradictory results, although the association was significant in the studies with a larger sample size and a higher number of events during follow-up. Conclusion. According to this review, alterations in lipid markers in childhood and adolescence are associated with a higher cardiovascular risk in early and middle adulthood.

Método indirecto para la verificación del intervalo de referencia del perfil lipídico / Indirect method for the verification of the lipid profile reference range

Introducción: La dislipidemia es uno de los problemas más frecuentes en los niños y adolescentes y su estudio es importante debido a su fuerte correlación con la enfermedad cardiovascular aterosclerótica en adultos. Muchos países desarrollaron valores de referencia nacionales investigando los lípidos séricos utilizando datos basados en la población nacional propia. Nuestro objetivo fue verificar el intervalo de referencia del perfil lipídico calculando las curvas de percentiles a través del método indirecto en nuestra población pediátrica. Materiales y métodos: Se analizaron los resultados de nuestra base de datos utilizando el método indirecto. Luego de aplicar filtros y criterios de exclusión se calcularon los percentiles 25, 50, 75, 95 y 99 para colesterol total (CT), colesterol HDL (C-HDL), colesterol no HDL (C-no-HDL), triglicéridos (TG) y colesterol LDL (C-LDL) y para el C-HDL además se calculó el percentil 10. El valor de referencia para el cambio (RCV) se utilizó para determinar si existía diferencia clínicamente significativa entre los valores de percentiles obtenidos y los utilizados en el consenso de la SAP. Resultados: No se evidenció diferencia clínicamente significativa contra los valores propuesto por la SAP, excepto para los TG para las edades 1,5,7 años en el percentil 95 y para la edad de 8 años en el percentil 75 y 95; para el C-HDL en el percentil 10 para las edades 1,16 y 17 años. Discusión: Se obtuvieron los percentiles de los lípidos y se compararon con los valores de referencia utilizados por el consenso en el que están basados las guías (AU)

Introduction: Dyslipidemia is one of the most common problems in children and adolescents and its study is important because of its strong correlation with atherosclerotic cardiovascular disease in adulthood. Many countries have developed national reference values investigating serum lipids using data based on their own national population. Our aim was to verify the lipid profile reference range by calculating percentile curves through the indirect method in our pediatric population. Materials and methods: The results of our database were analyzed using the indirect method. After applying filters and exclusion criteria, the 25th, 50th, 75th, 95th, and 99th percentiles were calculated for total cholesterol (TC), HDL cholesterol (HDL-C), non-HDL cholesterol (non-HDL-C), triglycerides (TG), and LDL cholesterol (LDL-C); for HDL-C, the 10th percentile was also calculated. The reference change values (RCV) were used to determine whether there was a clinically significant difference between the percentile values obtained and those used in the consensus of the Argentine Association of Pediatrics (SAP). Results: There was no clinically significant difference with the values proposed by the SAP, except for TG for ages 1, 5, and 7 years at the 95th percentile and for age 8 years at the 75th and 95th percentile; and for HDL-C at the 10th percentile for ages 1, 16, and 17 years. Discussion: Lipid percentiles were obtained and compared with the reference values used by the consensus on which the guidelines are based (AU)

Vitamin d levels and lipid profile in patients undergoing bariatric surgery / Níveis de vitamina d e perfil lipídico em pacientes submetidos à cirurgia bariátrica

ABSTRACT BACKGROUND: Vitamin, mineral, and metabolic deficiencies occur in the postoperative period of bariatric surgery, in the short and long term, and are worrisome intercurrences. AIMS: To evaluate the association of serum vitamin D levels with the lipid profile in obese patients undergoing bariatric surgery. METHODS: Case series of patients assisted from 2010 to 2018, in a private hospital of medium and high complexity, who underwent bariatric surgery using sleeve gastrectomy or Roux-en-Y gastric bypass techniques, monitored by the same surgeon. Sociodemographic, clinical, laboratory, and anthropometric data were collected preoperatively and at 6, 12, and 24 months after surgery. RESULTS: A total of 156 individuals, mostly female (75.6%) were monitored. The most frequent comorbidities were hepatic steatosis (76.3%) and hypertension (48.27). Regarding preoperative vitamin D levels, only 18.9% of the population had a satisfactory level (≥30 ng/mL). There was a reduction in weight and an improvement in the lipid profile after surgery. Significant correlations were observed between the lipid profile and vitamin D concentration only in the sample submitted to the Roux-en-Y gastric bypass technique: negative correlation between total cholesterol and vitamin D two years after surgery; positive correlation between triglycerides and vitamin D one year after surgery; and negative correlation between high-density lipoprotein and vitamin D two years post-surgery. CONCLUSIONS: It is essential to routinely monitor vitamin D levels and lipid profile pre- and postoperatively in order to avoid damage associated with this vitamin deficiency.

RESUMO RACIONAL: Deficiências vitamínicas, minerais e metabólicas ocorrem no pós-operatório de cirurgia bariátrica, a curto e longo prazo, sendo intercorrências preocupantes. OBJETIVOS: Avaliar a associação dos níveis séricos de vitamina D com o perfil lipídico, em pacientes obesos submetidos à cirurgia bariátrica. MÉTODOS: Série de casos de pacientes atendidos de 2010 até 2018, em hospital privado de média e alta complexidade, submetidos à cirurgia bariátrica pelas técnicas da gastrectomia vertical e derivação gástrica em Y de Roux, acompanhados pelo mesmo cirurgião. Foram coletados dados sociodemográficos, clínicos, dados laboratoriais e antropométricos no pré-operatório, 6 meses, 12 meses e 24 meses após cirurgia. RESULTADOS: Foram acompanhados 156 indivíduos, maioria sexo feminino (75,6%), comorbidades mais frequentes foram esteatose hepática (76,3%) e hipertensão (48,27). Em relação aos níveis de vitamina D pré-operatórios, apenas 18,9% da população apresentaram níveis satisfatórios (=30 ng/mL). Observou-se redução do peso e melhora do perfil lipídico pós-cirúrgico. Sobre as correlações entre o perfil lipídico e concentração de vitamina D foram observadas correlações significativas apenas na amostra que passou pela técnica cirúrgica derivação gástrica em Y de Roux: correlação negativa entre o colesterol total e vitamina D após 2 anos de cirurgia; correlação positiva entre triglicerídeo e vitamina D 1 ano pós-operatório; e correlação negativa entre HDL e vitamina D 2 anos pós-operatório. CONCLUSÕES: é essencial acompanhar os níveis de vitamina D e perfil lipídico no pré e pós-operatório de forma rotineira a fim de evitar danos relacionados a deficiência dessa vitamina.

Efeitos da suplementação de óleo de abacate sobre o perfil lipídico e índices aterogênicos em intervenção duplo-cego e randomizada em pacientes com síndrome metabólica / Effects of avocado oil supplementation on lipid profile and atherogenic indices in a double-blind and randomised intervention in patients with metabolic syndrome

Introdução: A síndrome metabólica é definida como um conjunto de condições clínicas que acometem cerca de 25% da população mundial e 29,6% dos brasileiros. Essa síndrome está relacionada ao aumento dos desfechos cardiovasculares, que podem ser preditos através do perfil lipídico. Compostos bioativos, tais como os ácidos graxos monoinsaturados (MUFA), são fortes aliados na prevenção desses desfechos. Um alimento importante por conter compostos bioativos e MUFA em abundância é o abacate. Há, porém, poucos estudos avaliando o efeito do óleo puro/virgem de abacate sobre o perfil lipídico em humanos com síndrome metabólica, e seus efeitos sobre os índices aterogênicos inexistem. Objetivo: O estudo buscou avaliar a suplementação de óleo de abacate sobre os níveis lipídicos e índices aterogênicos em pacientes portadores de síndrome metabólica. Método: 31 indivíduos adultos e obesos foram randomizados em grupo controle (óleo de soja) e grupo intervenção (óleo de abacate). Estes foram avaliados nos períodos pré e pós-intervenção (12 semanas) através de anamnese clínica e avaliação nutricional. Resultados: Observou-se que tanto o grupo controle quanto o grupo intervenção tinham a ingestão de lipídeos e gordura saturada maior que o recomendável. Quanto ao perfil lipídico e índices aterogênicos, não foi observada diferença significativa entre os períodos pré e pós. Conclusão: Os resultados podem ter se dado pela ausência do controle alimentar, sobrecarga de medicamentos, duração da intervenção, modo de administração e dose do suplemento. Logo, são necessários estudos futuros sobre os efeitos do óleo de abacate nessa população, que controlem melhor essas variáveis.

Introduction: Metabolic syndrome is defined as a set of clinical conditions that affect approximately 25% of the world's population and 29.6% of Brazilians. This syndrome is related to increased cardiovascular outcomes, which may be predicted by the lipid profile. Bioactive compounds, such as monounsaturated fatty acids (MUFAs), are strong allies in preventing these outcomes. Avocado is an important food because it contains abundant bioactive compounds and MUFAs. However, few studies evaluated the effects of pure/virgin avocado oil on the lipid profile in humans with metabolic syndrome, and its effects on atherogenic indices are not known. Objective:This study evaluated avocado oil supplementation on lipid levels and atherogenic indices in patients with metabolic syndrome. Method: Thirty-one obese adults were randomised into a control group (soybean oil) and an intervention group (avocado oil). These groups were evaluated in the pre- and post-intervention periods (12 weeks) via clinical anamnesis and nutritional assessment. Results: The control group and the intervention group had higher intakes of lipids and saturated fat than recommended. For the lipid profile and atherogenic indices, no significant difference was observed between the pre- and postintervention periods. Conclusion: These results may have been due to the absence of dietary control, medication overload, intervention duration, mode of administration and dose of the supplement. Therefore, future studies on the effects of avocado oil are needed in this population to better control these variables.

Predictive Effects of Different Insulin Resistance Indexes on Diabetes Risk in Hypertensive Population / 中国医学科学院学报

Objective To explore the roles of different insulin resistance indexes[triglyceride-glucose (TyG),triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C),and metabolic score for insulin resistance (METS-IR)]and combinations of two indexes in predicting diabetes risk in hypertensive population. Methods The survey of hypertension was conducted for the residents in Wuyuan county,Jiangxi province from March to August in 2018.The basic information of hypertensive residents was collected by interview.Blood was drawn on an empty stomach in the morning and physical measurements were carried out.Logistic regression model was employed to analyze the relationship between different insulin resistance indexes and diabetes,and the area under the receiver operating characteristic curve was used for evaluating the predictive effects of each index on diabetes risk. Results A total of 14 222 hypertensive patients with an average age of (63.8±9.4) years old were included in this study,including 2616 diabetic patients.The diabetic hypertensive population had higher TyG (t=50.323,P<0.001),TG/HDL-C (Z=17.325,P<0.001),and METS-IR (t=28.839,P<0.001) than the non-diabetic hypertensive population.Multivariate analysis showed that each insulin resistance index was positively correlated with diabetes risk.The area under curve of each insulin index was in a descending order of TyG (0.770)> METS-IR (0.673)> TG/HDL-C (0.620).The difference in the area under curve between two indexes was statistically significant[TyG vs.TG/HDL-C (Z=42.325,P<0.001);TyG vs.METS-IR(Z=17.517,P<0.001);METS-IR vs.TG/HDL-C (Z=10.502,P<0.001)]. Conclusions Elevated insulin resistance indexes can increase the risk of diabetes.TyG and the combination of indexes outperform TG/HDL-C and METS-IR in the prediction of diabetes.

Lower Baseline LDL Cholesterol Affects All-cause Mortality in Patients with First Percutaneous Coronary Intervention / 生物医学与环境科学（英文）

OBJECTIVE@#Foreign studies have reported that coronary artery disease (CAD) patients with high baseline low-density lipoprotein cholesterol (LDL-C) may have a good prognosis, which is called the "cholesterol paradox". This study aimed to examine whether the "cholesterol paradox" also exists in the Chinese population.@*METHODS@#A total of 2,056 patients who underwent the first percutaneous coronary intervention (PCI) between 2014 and 2016 were enrolled in this retrospective cohort study and classified into two groups based on baseline LDL-C = 2.6 mmol/L (100 mg/dL). The outcomes of interest included major adverse cardiovascular events (MACE), all-cause mortality, recurrent nonfatal myocardial infarction, unexpected coronary revascularization, or any nonfatal stroke.@*RESULTS@#All-cause mortality occurred in 8 patients (0.7%) from the low-LDL-C group and 12 patients (2.4%) in the high-LDL-C group, with a significant difference between the two groups (adjusted hazard ratio: 4.030, 95% confidence interval: 1.088-14.934; P = 0.037). However, no significant differences existed for the risk of MACE or other secondary endpoints, such as unexpected revascularization, nor any nonfatal stroke in the two groups.@*CONCLUSION@#In this study, a high baseline LDL-C was not associated with a low risk of clinical outcomes in CAD patients undergoing first PCI, which suggested that the "cholesterol paradox" may be inapplicable to Chinese populations.

Geographic Variations in the Prevalence, Awareness, Treatment, and Control of Dyslipidemia among Chinese Adults in 2018-2019: A Cross-sectional Study / 生物医学与环境科学（英文）

OBJECTIVE@#To investigate the spatial patterns of the prevalence, awareness, treatment, and control rates of dyslipidemia at the provincial level in China.@*METHODS@#A national and provincial representative cross-sectional survey was conducted among 178,558 Chinese adults in 31 provinces in mainland China in 2018-2019, using a multi-stage, stratified, cluster-randomized sampling design. Subjects, as households, were selected, followed by a home visit to collect information. Both descriptive and linear regression procedures were applied in the analyses.@*RESULTS@#The overall prevalence of dyslipidemia was 35.6%, and wide geographic variations of prevalence, treatment, and control rates of dyslipidemia were identified among 178,558 eligible participants with a mean age of 55.1 ± 13.8 years. The highest-lowest difference regarding the provincial level prevalence rates were 19.7% vs. 2.1% for high low-density lipoprotein cholesterol, 16.7% vs. 2.5% for high total cholesterol, 35.9% vs. 5.4% for high triglycerides, and 31.4% vs. 10.5% for low high-density lipoprotein cholesterol. The treatment rate of dyslipidemia was correlated with the socio-demographic index ( P < 0.001), urbanization rate ( P = 0.01), and affordable basic technologies and essential medicines ( P < 0.001).@*CONCLUSION@#Prevailing dyslipidemia among the Chinese population and its wide geographic variations in prevalence, treatment, and control suggest that China needs both integrated and localized public health strategies across provinces to improve lipid management.

The impact of LDL-C/HDL-C ratio on severity of coronary artery disease and 2-year outcome in patients with premature coronary heart disease: results of a prospective, multicenter, observational cohort study / 中华心血管病杂志

Objective: To explore the relationship between low density lipoprotein cholesterol (LDL-C)/high density lipoprotein cholesterol (HDL-C) ratio with the severity of coronary artery disease and 2-yeat outcome in patients with premature coronary heart disease. Methods: This prospective, multicenter, observational cohort study is originated from the PROMISE study. Eighteen thousand seven hundred and one patients with coronary heart disease (CHD) were screened from January 2015 to May 2019. Three thousand eight hundred and sixty-one patients with premature CHD were enrolled in the current study. According to the median LDL-C/HDL-C ratio (2.4), the patients were divided into two groups: low LDL-C/HDL-C group (LDL-C/HDL-C≤2.4, n=1 867) and high LDL-C/HDL-C group (LDL-C/HDL-C>2.4, n=1 994). Baseline data and 2-year major adverse cardiovascular and cerebrovascular events (MACCE) were collected and analyzed in order to find the differences between premature CHD patients at different LDL-C/HDL-C levels, and explore the correlation between LDL-C/HDL-C ratio with the severity of coronary artery disease and MACCE. Results: The average age of the low LDL-C/HDL-C ratio group was (48.5±6.5) years, 1 154 patients were males (61.8%); the average age of high LDL-C/HDL-C ratio group was (46.5±6.8) years, 1 523 were males (76.4%). The number of target lesions, the number of coronary artery lesions, the preoperative SNYTAX score and the proportion of three-vessel coronary artery disease in the high LDL-C/HDL-C group were significantly higher than those in the low LDL-C/HDL-C group (1.04±0.74 vs. 0.97±0.80, P=0.002; 2.04±0.84 vs. 1.85±0.84, P<0.001; 13.81±8.87 vs. 11.70±8.05, P<0.001; 36.2% vs. 27.4%, respectively, P<0.001). Correlation analysis showed that there was a significant positive correlation between LDL-C/HDL-C ratio and preoperative SYNTAX score, the number of coronary artery lesions, the number of target lesions and whether it was a three-vessel coronary artery disease (all P<0.05). The 2-year follow-up results showed that the incidence of MACCE was significantly higher in the high LDL-C/HDL-C group than that in the low LDL-C/HDL-C group (6.9% vs. 9.1%, P=0.011). There was no significant difference in the incidence of all-cause death, cardiac death, myocardial infarction, stroke, revascularization and bleeding between the two groups. Cox multivariate regression analysis showed that the LDL-C/HDL-C ratio has no correlation with 2-year MACCE, death, myocardial infarction, revascularization, stroke and bleeding events above BARC2 in patients with premature CHD. Conclusion: High LDL-C/HDL-C ratio is positively correlated with the severity of coronary artery disease in patients with premature CHD. The incidence of MACCE of patients with high LDL-C/HDL-C ratio is significantly higher during 2 years follow-up; LDL-C/HDL-C ratio may be an indicator for evaluating the severity of coronary artery disease and long-term prognosis in patients with premature CHD.

Association between Serum Uric Acid to HDL-Cholesterol Ratio and Nonalcoholic Fatty Liver Disease Risk among Chinese Adults / 生物医学与环境科学（英文）

OBJECTIVE@#The aim of this case-control study was to explore the association between serum uric acid to high density lipoprotein cholesterol ratio (UHR) and the risk of nonalcoholic fatty liver disease (NAFLD) in Chinese adults.@*METHODS@#A total of 636 patients with NAFLD and 754 controls were enrolled from the Affiliated Hospital of Qingdao University, China, between January and December 2016. All patients completed a comprehensive questionnaire survey and underwent abdominal ultrasound examination and a blood test. NAFLD was diagnosed using ultrasonography after other etiologies were excluded. Logistic regression and restricted cubic spline model were conducted to evaluate the relationship of UHR with NAFLD risk.@*RESULTS@#The multivariable adjusted odds ratio (95% confidence interval, CI) for NAFLD in the highest versus lowest quartile of UHR was 3.888 (2.324-6.504). In analyses stratified by sex and age, we observed significant and positive associations between UHR and the risk of NAFLD in each subgroup. In analyses stratified by body mass index (BMI), a significant and positive association was found only in individuals with a BMI of ≥ 24 kg/m2. Our dose-response analysis indicated a linear positive correlation between UHR and the risk of NAFLD.@*CONCLUSION@#UHR is positively associated with the risk of NAFLD and may serve as an innovative and noninvasive marker for identifying individuals at risk of NAFLD.

Rosuvastatin acts on the lymphatic system to improve atherosclerosis / 中华心血管病杂志

Objective: To investigate whether rosuvastatin acts on lymphatic system and influences lymphatic system-mediated reverse cholesterol transport to play an anti-atherosclerosis role. Methods: Forty-eight apolipoprotein E-/- mice fed a high fat diet were used to construct the atherosclerosis model. They were randomly divided into 4 groups with 12 rats in each group. They were treated with rosuvastatin, vascular endothelial growth factor-C (VEGF-C) and rosuvastatin+VEGF-C inhibitors as experimental group, and no intervention measures were given in control group. After 8 weeks, aortic plaque area, high density lipoprotein cholesterol (HDL-C) content in lymph fluid, the function of popliteal lymphatic drainage of peripheral Evans blue, and the ability of lymphatic system to transport peripheral cell membrane red fluorescent probes to label high-density lipoprotein (HDL) were detected. Subsequently, the effects of rosuvastatin on proliferation, migration and tubular function of lymphoendothelial cells and the expression of scavenger receptor class B type 1 (SR-B1) on lymphoendothelial cells at different concentrations were detected. Results: Compared with the control group, Rosuvastatin and VEGF-C could reduce the area of aortic atherosclerotic plaque (P<0.05). In addition to rosuvastatin plus VEGF-C inhibitor, the intra-aortic plaque area increased (P<0.05). Compared with the control group, Rosuvastatin could increase the content of HDL-C in lymphatic fluid (P<0.05), enhance the drainage function of lymphatic vessels, and enhance the capacity of HDL in the transport tissue fluid of lymphatic system. Compared with the control group, VEGF-C increased the content of HDL-C in mouse lymph fluid (P<0.01), enhanced the drainage function of popliteal lymphatic canal, and enhanced the ability of lymphatic system to transport HDL. With the addition of VEGF-C inhibitor on the basis of rosuvastatin, the content of HDL-C in lymph fluid was reduced, the drainage of popliteal lymphatic canal was interrupted, and the ability of lymphatic system to transport HDL was reduced. Western blotting showed that rosuvastatin increased the protein expression of SR-B1. Conclusion: Rosuvastatin can promote the proliferation, migration and tube formation of lymphatic endothelial cells. At the same time, SR-B1 expression on lymphatic endothelial cells is promoted, thus enhancing the lymphatic system mediated cholesterol reversal transport and playing the role of anti-atherosclerosis.

Associations between various lipid components and premature myocardial infarction: a cross-sectional study / 中华心血管病杂志

Objective: Hyperlipidemia is closely related to premature acute myocardial infarction (AMI). The present study was performed to explore the correlation between various blood lipid components and the risk of premature AMI. Methods: This is a cross-sectional retrospective study. Consecutive patients with acute ST-segment elevation myocardial infarction (STEMI), who completed coronary angiography from October 1, 2020 to September 30, 2022 in our hospital, were enrolled and divided into premature AMI group (male<55 years old, female<65 years old) and late-onset AMI group. Total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), non-HDL-C, lipoprotein (a) (Lp (a)), apolipoprotein B (ApoB), apolipoprotein A-1 (ApoA-1), non-HDL-C/HDL-C and ApoB/ApoA-1 were analyzed. The correlation between the above blood lipid indexes and premature AMI was analyzed and compared by logistic regression, restricted cubic spline and receiver operating characteristic curve (ROC). Results: A total of 1 626 patients with STEMI were enrolled in this study, including 409 patients with premature AMI and 1 217 patients with late-onset AMI. Logistic regression analysis showed that the risk of premature AMI increased significantly with the increase of TG, non-HDL-C/HDL-C, non-HDL-C, ApoB/ApoA-1, TC and ApoB quintiles; while LDL-C, ApoA-1 and Lp (a) had no significant correlation with premature AMI. The restricted cubic spline graph showed that except Lp (a), LDL-C, ApoA-1 and ApoB/ApoA-1, other blood lipid indicators were significantly correlated with premature AMI. The ROC curve showed that TG and non-HDL-C/HDL-C had better predictive value for premature AMI. Inconsistency analysis found that the incidence and risk of premature AMI were the highest in patients with high TG and high non-HDL-C/HDL-C. Conclusion: TG, non-HDL-C/HDL-C and other blood lipid indexes are significantly increased in patients with premature AMI, among which TG is the parameter, most closely related to premature AMI, and future studies are needed to explore the impact of controlling TG on incidence of premature AMI.

Relationship between atherogenic index of plasma and childhood asthma / 中国当代儿科杂志

OBJECTIVES@#To explore the relationship between atherogenic index of plasma (AIP) and childhood asthma.@*METHODS@#This retrospective study included 86 children with asthma admitted to the Changzhou Second People's Hospital Affiliated to Nanjing Medical University from July 2020 to August 2022 as the asthma group and 149 healthy children undergoing physical examination during the same period as the control group. Metabolic parameters including total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and blood glucose, as well as general information of the children such as height, weight, body mass index, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, and feeding history, were collected. Multivariable logistic regression analysis was used to study the relationship between AIP, triglycerides, and high-density lipoprotein cholesterol and asthma. The value of AIP, triglycerides, and high-density lipoprotein cholesterol for predicting asthma was assessed using receiver operating characteristic (ROC) curve analysis.@*RESULTS@#The AIP and triglyceride levels in the asthma group were significantly higher than those in the control group, while high-density lipoprotein cholesterol was significantly lower (P<0.05). However, there was no significant difference in total cholesterol and low-density lipoprotein cholesterol between the two groups (P>0.05). Before and after adjusting for height, weight, presence of specific dermatitis, history of inhalant allergen hypersensitivity, family history of asthma, feeding method, and blood glucose, multivariable logistic regression analysis showed that AIP, triglycerides, and high-density lipoprotein cholesterol were associated with asthma (P<0.05). ROC curve analysis showed that the optimal cutoff value for predicting asthma with AIP was -0.333, with a sensitivity of 80.2%, specificity of 55.0%, positive predictive value of 50.71%, and negative predictive value of 82.85%. The area under the curve (AUC) for AIP in predicting asthma was significantly higher than that for triglycerides (P=0.009), but there was no significant difference in AUC between AIP and high-density lipoprotein cholesterol (P=0.686).@*CONCLUSIONS@#AIP, triglycerides, and high-density lipoprotein cholesterol are all associated with asthma. AIP has a higher value for predicting asthma than triglycerides and comparable value to high-density lipoprotein cholesterol.

A cross-sectional study on the prevalence rate and influencing factors of non-alcoholic fatty liver disease in overweight/obese children / 中国当代儿科杂志

OBJECTIVES@#To investigate the prevalence rate of non-alcoholic fatty liver disease (NAFLD) in overweight/obese children who visit a hospital, and to explore the influencing factors of NAFLD, in order to provide a basis for the prevention of NAFLD in overweight/obese children.@*METHODS@#Overweight/obese children who visited Hunan Children's Hospital from June 2019 to September 2021 were recruited. The prevalence rate of NAFLD was examined. Logistic regression analysis was used to explore the factors influencing the development of NAFLD [non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH)]. Receiver operating characteristic curve analysis was used to evaluate the predictive value of the influencing factors for NAFL and NASH.@*RESULTS@#A total of 844 overweight/obese children aged 6-17 years were enrolled. The prevalence rate of NAFLD in overweight/obese children was 38.2% (322/844), among which the prevalence rates of NAFL and NASH were 28.8% (243/844) and 9.4% (79/844), respectively. Multivariate logistic regression analysis showed that the increase of waist-to-hip ratio (WHR) and low high-density lipoprotein cholesterol (HDL-C) were associated with the development of NAFL and NASH (P<0.05). The receiver operating characteristic curve analysis showed that the combined measurement of WHR and HDL-C had a predictive value for NAFL (area under the curve: 0.653, 95%CI: 0.613-0.694), and for NASH (area under the curve: 0.771, 95%CI: 0.723-0.819).@*CONCLUSIONS@#The prevalence rate of NAFLD in overweight/obese children who visit a hospital is high. WHR and HDL-C are associated with the development of NAFLD and the combined measurement of WHR and HDL-C has a certain value for predicating the development of NAFLD.

¿Es el colesterol no-HDL un indicador de riesgo cardiovascular en las personas con diabetes mellitus? / Is non-HDL cholesterol a risk marker for cardiovascular atherosclerotic disease in diabetes mellitus?

La diabetes mellitus tipo 2 (DM2) es un factor de riesgo cardiovascular (FRCV) mayor. La DM confiere dos a cuatro veces más riesgo cardiovascular (RCV). El riesgo es aún más elevado en el paciente con DM2 que ha sufrido un infarto agudo de miocardio (IAM) o un accidente cerebrovascular (ACV). La dislipidemia de la DM2 consiste en triglicéridos elevados de ayuno, con mayor excursión posprandial, bajos niveles de HDLc, y alteraciones cuantitativas y cualitativas de LDLc y HDLc. El control glucémico apropiado en DM2 mejora en gran medida las alteraciones lipoproteicas. La terapia hipolipemiante es clave para reducir el RCV en la DM2. La reducción del RCV que se consigue con estatinas se basa en la reducción del LDLc y sus efectos pleiotrópicos. En pacientes que persisten con el perfil lipídico alterado, a pesar de dosis altas de estatinas, se debe considerar el agregado de otros agentes hipolipemiantes para reducir las lipoproteínas aterogénicas.

Type 2 diabetes (T2D) is a major cardiovascular risk factor (CVRF). Diabetes confers two to four times more cardiovascular risk (CVR). The risk is even higher in patients with T2D who have suffered an acute myocardial infarction (AMI) or cerebrovascular accident (CVA). The dyslipidemia of T2D consists of high fasting triglycerides, with greater postprandial excursion, low levels of HDLc and qualitative alterations of LDLc and HDLc. Appropriate glycemic control in T2D greatly improves lipoprotein abnormalities. Lipid-lowering therapy is key to reducing CVR in T2D. The CVR reduction achieved with statins is based on the reduction of LDLc. In patients who persist with an altered lipid profile despite highdose statins, the addition of other lipid-lowering agents to reduce atherogenic lipoproteins may be considered.

Impacto de la cuarentena por COVID-19 en el perfil metabólico de personas con infección por VIH en Argentina / Impact of COVID-19 related lockdown on the metabolic profile of people with HIV infection in Argentina

INTRODUCCIÓN: Para mitigar la propagación del SARS-CoV-2 se requirió de un confinamiento generalizado. Las autoridades argentinas impusieron aislamiento social preventivo durante 234 días (20 de marzo al 9 de noviembre de 2020), modificando el estilo de vida de la población. OBJETIVOS: Examinar la influencia de las medidas de bloqueo en el perfil metabólico de pacientes infectados por VIH en Argentina. PACIENTES Y MÉTODOS: Estudio de cohorte retrospectivo de 10.239 pacientes en seguimiento en una clínica de atención privada de personas con infección por VIH. Se incluyeron pacientes adultos con terapia antirretroviral (TARV) en curso que tuvieran una determinación de glucemia, colesterol total, colesterol HDL y trigliceridemia antes de la cuarentena (Pre-C: segundo semestre 2019) y una segunda determinación durante la misma (Intra-C: mayo 2020). Se excluyeron los pacientes con cambios en la TARV con impacto metabólico, los que iniciaron o suspendieron hipolipemiantes o hipoglucemiantes y mujeres embarazadas. Las variables categóricas se compararon mediante la prueba de la χ2 o la prueba exacta de Fisher y las continuas mediante la prueba t o la prueba de Mann-Whitney según correspondiera. Se consideró significativo un valor de p a dos colas < 0,05. RESULTADOS: Se incluyeron 540 individuos. La mediana de edad fue de 47 años y 74,6% fueron de sexo masculino. La mediana de índice de masa corporal fue 26,1 y 94,6% tenían bajo riesgo cardiovascular. Hubo un aumento significativo en el porcentaje de pacientes con hiperglucemia (Pre-C 5,2% vs Intra-C 8,5%, p 0,04), hipertrigliceridemia (Pre-C 33,9% vs Intra-C 40,7%, p 0,02) e hipercolesterolemia LDL (Pre-C 12,6% vs Intra-C 17,2%, p 0,04). CONCLUSIÓN: Nuestros resultados sugieren que la cuarentena, al menos en sus fases iniciales, puede tener un impacto negativo en el perfil metabólico de esta población.

BACKGROUND: The spread of SARS-CoV-2 required widespread lockdown to mitigate the pandemic. Argentine authorities imposed preventive social isolation for 234 days (March 20th to November 9th 2020). This measure led to major changes in the population's lifestyle. AIM: To examine the influence of COVID-19 lockdown measures on the metabolic profile of HIV-infected patients in Argentina. METHODS: Retrospective cohort study of 10,239 HIV-infected patients under follow up in a private clinic for HIV care. Adult patients with ongoing antiretroviral therapy (ART) and a baseline determination of blood glucose, total cholesterol, HDL-cholesterol and triglycerides done before lockdown (BL: second semester of 2019) and a second determination during lockdown (DL: May 2020) were included. Patients with recent changes in ART that may have metabolic impact, those starting lipid/glucose lowering agents and pregnant women were excluded. Categorical variables were compared using the χ2 test or Fisher's exact test, and continuous variables using the t-test or the Mann-Whitney test. A two-tailed value of p < 0.05 was considered significant. RESULTS: 540 individuals were included, median of age was 47 years and 74.6% were male. Median body mass index was 26.1 and 94.6% had low cardiovascular risk. There was a significant increase in the percentage of patients that met criteria for hyperglycemia (BL 4.8% and DL 8.5%, p < 0.001). We also observed significant (p < 0.001) increase in median (IQR) BL vs DL values in LDL-cholesterol [109 (90-128) vs 118 (97-139) mg/dL]; and triglycerides [120 (87-172) vs. 132 mg/dL (96-184)]. The proportion of patients with hyper-LDL cholesterolemia according to individual cardiovascular risk increased from 12.6 to 17.2% (p = 0.04). CONCLUSION: Our results suggest that quarantine, at least in its initial phases, may have a negative impact on the metabolic profile of this population.

The effect of kefir consumption on the lipid profile for individuals with normal and dyslipidemic properties: a randomized controlled trial / O efeito do consumo de kefir no perfil lipídico em indivíduos com propriedades normais e dislipidêmicas: um ensaio clínico randomizado

ABSTRACT Objective This research was conducted as a prospective, self-controlled, eight-week clinical trial to investigate the effect of kefir consumption on the lipid profile of individuals with normal and dyslipidemic properties. Methods Kefir microorganisms given to volunteer subjects were determined using classical microbial count methods and qReal-Time Polymerase Chain Reaction. The study was carried out with 23 volunteer hospital health personnel between the ages of 20 and 55 who met the research criteria and did not have any health problems. The volunteers regularly consumed kefir on an empty stomach for four weeks. In the last stage, the eight-week study was completed by making blood and anthropometric measurements of the subjects, who continued to be studied without kefir consumption for four more weeks. Results Considering the changes in the serum lipid profiles of 13 individuals with dyslipidemic symptoms during the 4-week period they consumed kefir, Total Cholesterol values decreased by 9.15% compared to initial values, LDL-Cholesterol values decreased by 10.64%, HDL-Cholesterol values decreased by 6.9%, and triglyceride values decreased by 2.46%. The changes in the serum lipid profiles of 13 individuals with dyslipidemic findings at the end of an eight-week study were a 5.71% decrease in total cholesterol values (p<0.018) considered statistically significant, as well as a 5.31% decrease in LDL-Cholesterol values (p<0.021); the HDL-Cholesterol results were found to be significant with an 8.58% decrease in the values (p<0.035) and insignificant with a 17.21% increase in the triglyceride values (p<0.926). We concluded that regular kefir consumption was effective in both women and men in lowering total cholesterol and LDL-Cholesterol from blood lipid profiles, especially in individuals with dyslipidemic symptoms, while this effect was not observed in normal individuals. Conclusion Kefir can positively affect the total cholesterol and LDL-Cholesterol blood parameters of dyslipidemic individuals with high serum lipid values.

RESUMO Objetivo Esta pesquisa foi conduzida como um ensaio clínico prospectivo e autocontrolado de oito semanas para investigar o efeito do consumo de kefir no perfil lipídico de indivíduos com propriedades normais e dislipidêmicas. Métodos Microrganismos kefir dados a voluntários foram determinados usando métodos clássicos de contagem microbiana e de reação em cadeia da polimerase em tempo real. O estudo foi conduzido em 23 profissionais de saúde de hospitais voluntários, com idades entre 20 e 55 anos, que atendiam aos critérios da pesquisa e não apresentavam problemas de saúde. Os voluntários consumiram kefir com o estômago vazio regularmente durante quatro semanas. No último estágio, o estudo de oito semanas foi concluído com medidas de sangue e antropométricas dos indivíduos, que continuaram a ser avaliados sem consumo de kefir por mais quatro semanas. Resultados Considerando as mudanças nos perfis lipídicos séricos de 13 indivíduos com sintomas dislipidêmicos durante o período de quatro semanas em que consumiram kefir, os valores de colesterol total diminuíram em 9,15% em comparação com os valores iniciais; os valores de LDL-Colesterol diminuíram em 10,64%, os valores de HDL-Colesterol diminuíram em 6,9% e os valores de triglicerídeos diminuíram em 2,46%. Ao final de um estudo de oito semanas, o resultado foi considerado estatisticamente significativo, com queda de 5,71% nos valores de colesterol total (p<0,018); de 5,31% nos valores de Colesterol-LDL (p<0,021) e de 8,58% nos valores de HDL-Colesterol (p <0,035), e insignificantes com aumento de 17,21% nos valores de triglicerídeos (p<0,926). Como resultado do estudo, concluiu-se que o consumo regular de kefir foi eficaz em mulheres e homens na redução do colesterol total e do LDL-Colesterol dos perfis de lipídios no sangue, especialmente em indivíduos com sintomas dislipidêmicos, enquanto esse efeito não foi observado em indivíduos normais. Conclusão O kefir pode afetar positivamente os parâmetros sanguíneos do colesterol total e do LDL-Colesterol de indivíduos dislipidêmicos com altos valores de lipídios séricos.

Early predictive value of high density lipoprotein cholesterol for secondary acute kidney injury in sepsis patients / 中华烧伤杂志

Objective: To investigate the changes of high density lipoprotein cholesterol (HDL-C) in sepsis patients and its early predictive value for secondary acute kidney injury (AKI) in such patients. Methods: A retrospective case series study was conducted. From June 2019 to June 2021, 232 sepsis patients who met the inclusion criteria were admitted to the Second Hospital of Hebei Medical University, including 126 males and 106 females, aged 24 to 71 years. According to whether complicating secondary AKI, the patients were divided into non-AKI group (n=158) and AKI group (n=74). Data of patients between the two groups were compared and statistically analyzed with independent sample t test or chi-square test, including the sex, age, body mass index (BMI), body temperature, heart rate, primary infection site, combined underlying diseases, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score and sepsis-related organ failure assessment (SOFA) score at admission, and the serum levels of C-reactive protein (CRP), procalcitonin, creatinine, cystatin C, and HDL-C measured at diagnosis of sepsis. The multivariate logistic regression analysis was performed on the indicators with statistically significant differences between the two groups to screen the independent risk factors for developing secondary AKI in 232 sepsis patients, and the joint prediction model was established based on the independent risk factors. The receiver operating characteristic (ROC) curve of the independent risk factors and the joint prediction model predicting secondary AKI in 232 sepsis patients were drawn, and the area under the curve (AUC), the optimal threshold, and the sensitivity and specificity under the optimal threshold were calculated. The quality of the above-mentioned AUC was compared by Delong test, and the sensitivity and specificity under the optimal threshold were compared using chi-square test. Results: The sex, age, BMI, body temperature, heart rate, primary infection site, combined underlying diseases, and CRP level of patients between the two groups were similar (P>0.05). The procalcitonin, creatinine, cystatin C, and scores of APACHE Ⅱ and SOFA of patients in AKI group were all significantly higher than those in non-AKI group (with t values of -3.21, -16.14, -12.75, -11.13, and -12.88 respectively, P<0.01), while the HDL-C level of patients in AKI group was significantly lower than that in non-AKI group (t=6.33, P<0.01). Multivariate logistic regression analysis showed that creatinine, cystatin C, and HDL-C were the independent risk factors for secondary AKI in 232 sepsis patients (with odds ratios of 2.45, 1.68, and 2.12, respectively, 95% confidence intervals of 1.38-15.35, 1.06-3.86, and 0.86-2.56, respectively, P<0.01). The AUCs of ROC curves of creatinine, cystatin C, HDL-C, and the joint prediction model for predicting secondary AKI in 232 sepsis patients were 0.69, 0.79, 0.89, and 0.93, respectively (with 95% confidence intervals of 0.61-0.76, 0.72-0.85, 0.84-0.92, and 0.89-0.96, respectively, P values all below 0.01); the optimal threshold were 389.53 μmol/L, 1.56 mg/L, 0.63 mmol/L, and 0.48, respectively; the sensitivity under the optimal threshold were 76.6%, 81.4%, 89.7%, and 95.5%, respectively; the specificity under the optimal threshold values were 78.6%, 86.7%, 88.6%, and 96.6%, respectively. The AUC quality of cystatin C was significantly better than that of creatinine (z=2.34, P<0.05), the AUC quality and sensitivity and specificity under the optimal threshold of HDL-C were all significantly better than those of cystatin C (z=3.33, with χ2 values of 6.43 and 7.87, respectively, P<0.01) and creatinine (z=5.34, with χ2 values of 6.32 and 6.41, respectively, P<0.01); the AUC quality and sensitivity and specificity under the optimal threshold of the joint prediction model were all significantly better than those of creatinine, cystatin C, and HDL-C (with z values of 6.18, 4.50, and 2.06, respectively, χ2 values of 5.31, 7.23, 3.99, 6.56, 7.34, and 4.00, respectively, P<0.05 or P<0.01). Conclusions: HDL-C level in sepsis patients with secondary AKI is significantly lower than that in patients without secondary AKI. This is an independent risk factor for secondary AKI in sepsis patients with a diagnostic value being superior to that of creatinine and cystatin C. The combination of the aforementioned three indicators would have higher predicative valuable for secondary AKI in sepsis patients.

Relationship between pesticide exposure and lipid metabolism in population / 中华劳动卫生职业病杂志

Objective: To investigate the effect of pesticides and herbicides on lipid metabolism. Methods: In November 2020, Based on the data of the national health and Nutrition Survey (NHANES) (2011-2014) , select the population aged 20~65 who have demographic information, pesticide use and data of four lipid metabolism indicators [total cholesterol (TC) , triglyceride (TG) , high density lipoprotein cholesterol (HDLC) and low density lipoprotein cholesterol (LDLC) ] (n=3039) . The subjects were divided into insecticide group (320 people) and non insecticide group (2719) according to the use of insecticides, and herbicide group (156 people) and non herbicide group according to the use of herbicides. Results: Among the 3039 subjects, the males and female were 1509 (49.7%) and 1530 (50.3%) respectively. The males age was (39.7±12.0) years and the females age was (40.2±12.0) years The concentration of HDLC in the NHANES (55.4±15.0) mg/dl was lower than that of (58.2±14.2) mg/dL in the non herbicide group (P<0.05) (b=-0.044, P<0.05) . The results showed that the use of herbicides was related to the decrease of HDLC and the increase of LDLC and LDLC/HDLC in female population (b=-0.050, 0.062, 0.067, all P<0.05) . Conclusion: Herbicide exposure can cause the change of lipid metabolism, and the effect on female population is more obvious.

Correlation of serum lipids levels of Alzheimer's disease patients with sex, age and apolipoprotein E gene polymorphism / 中华预防医学杂志

Objective: To explore the correlation of serum lipids levels of Alzheimer's disease (AD) patients with sex, age and apolipoprotein E (Apo E) gene polymorphism. Methods: The retrospective study method was used, and 407 AD patients (142 males and 265 females, aged 52-91 years) were selected from Beijing Tiantan Hospital from January 2015 to August 2021 as the research target, and 894 healthy persons (339 males and 555 females, aged 52-94 years) who did body examination were selected as the control group. The AD patients were divided into four age groups according to the age interval of 10 years, including 85 aged 50-59 years, 163 aged 60-69 years, 119 aged 70-79 years, and 40 aged more than 80 years. The serum lipids levels were detected by biochemical analyzer, including triglycerides (TG), cholesterol (CHO), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoproteinA1(Apo A1) and apolipoprotein B (Apo B). ApoE gene polymorphism were detected by PCR fluorescent probe method. Mann-Whitney U test and Kruskal-Wallis H test were used to compare the serum lipids levels in each group. Results: The levels of serum CHO and LDL-C were 3.30(1.41,4.82) mmol/L and 1.76(1.39,2.78) mmol/L in AD patients, and 4.84(4.24, 5.56) mmol/L and 2.91(2.36, 3.57) mmol/L in control group, and the levels of serum CHO and LDL-C of AD patients were significantly lower than control group (Z=-15.172,Z=-14.583 , P<0.001, P<0.001). The levels of serum HDL-C and Apo B were 1.84(1.30, 3.88) mmol/L and 1.17(0.85, 1.57) g/L in AD patients, and 1.39(1.18, 1.64) mmol/L and 0.93(0.81, 1.09) g/L in control group, and the levels of serum HDL-C and Apo-B of AD patients were significantly higher than control group (Z=-12.249 , Z=-9.706 , P<0.001, P<0.001). There was no significant difference in TG and Apo A1 between 2 groups (Z=-1.577 , Z=-0.408 , P=0.115, P=0.683). The levels of TG, CHO, LDL-C in female AD patients were significantly higher than male patients (Z=-2.737 , Z=-3.963 , Z=-4.417, P=0.006, P<0.001, P<0.001). There were significant differences in TG, CHO, HDL-C, LDL-C, Apo A1 and Apo B among AD patients of all age groups (Z=11.263 , Z=10.060 , Z=40.246 , Z=10.451 , Z=24.315 , Z=19.922 , P=0.010 , P=0.018 , P<0.001 , P=0.015 , P<0.001 , P<0.001). The serum CHO and LDL-C levels were positively correlated with age (rs=0.160, rs=0.174, P=0.001, P<0.001), and HDL-C, Apo A1 and Apo B levels were negatively correlated with age (rs=-0.312, rs=-0.272, rs=-0.146, P<0.001, P<0.001, P=0.003), and there was no correlation between TG level and age in AD patients (rs=0.086, P=0.082). There were 3 cases (3.33%) of E2, 43 cases of E3 (47.78%) and 44 cases of E4 (48.89%) in AD patients, and 22 cases (12.72%) of E2, 117 cases of E3 (67.63%) and 34 cases of E4 (19.65%) in control group. There was significant difference in Apo E genotype distribution between AD patients and control group (χ²=26.381 , P<0.001). Apo E4 was the most common genotype in AD patients, and the proportion was 48.89%. Except for Apo A1(Z=7.821 , P=0.020), there was no significant difference in TG, CHO, HDL-C, LDL-C and Apo B levels among all patients with different genotypes (Z=3.732 , Z=1.677 , Z=1.455 , Z=1.619 , Z=2.202 , P=0.155, P=0.432, P=0.483, P=0.445, P=0.333). Conclusion: The levels of CHO and LDL-C decreased while the levels of HDL-C and Apo B increased in AD patients. The dyslipidemia in AD patients might be correlated with age, but not sex and Apo E genotypes.
